The Best Air Purifiers for Eliminating VOCs and Formaldehyde

The Best Air Purifier for VOCs and Formaldehyde to Create a Healthy Home

Indoor air quality is often worse than outdoor air quality due to the buildup of airborne pollutants inside our homes. Volatile organic compounds (VOCs) and formaldehyde are two major indoor air pollutants that can cause health issues when exposure is high. Using an air purifier designed to remove these pollutants can greatly improve indoor air quality and protect your health.

What are VOCs?

VOCs are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Concentrations of many VOCs are consistently higher indoors (up to ten times higher) than outdoors. VOCs are emitted by a wide array of products numbering in the thousands. Examples include:

Paints and lacquers
Paint strippers
Cleaning supplies
Pesticides
Building materials and furnishings
Office equipment such as copiers and printers
Correction fluids and carbonless copy paper
Graphics and craft materials including glues and adhesives, permanent markers, and photographic solutions
Hobbies
Dry-cleaned clothing
Air fresheners
Personal care products
Disinfectants

Organic chemicals are widely used as ingredients in household products. Paints, varnishes, and wax all contain organic solvents, as do many cleaning, disinfecting, cosmetic, degreasing, and hobby products. Fuels are made up of organic chemicals. All of these products can release organic compounds while you are using them, and, to some degree, when they are stored.

Health Effects of VOCs

Exposure to VOCs can cause both short-term and long-term health effects. General symptoms include:

Eye, nose, and throat irritation
Headaches
Loss of coordination
Nausea
Damage to liver, kidney, and central nervous system

Formaldehyde is classified as a human carcinogen and benzene exposure is associated with leukemia. Other health effects include:

Eye, nose, and throat irritation
Wheezing and allergic reactions
Fatigue
Skin rashes

Some organics can cause cancer in animals; some are suspected or known to cause cancer in humans. The ability of organic chemicals to cause health effects varies greatly from those that are highly toxic, to those with no known health effects. As with other pollutants, the extent and nature of the health effect will depend on many factors including level of exposure and length of time exposed.

What is Formaldehyde?

Formaldehyde is a colorless, strong-smelling gas commonly used in pressed-wood products, composite wood products, and furniture made with pressed wood products. It is also commonly used as an industrial fungicide, germicide, and disinfectant, and as a preservative in mortuaries and medical laboratories.

Formaldehyde is naturally occurring and can also be produced in small amounts by most living organisms as part of normal metabolic processes. However, elevated levels can cause adverse health effects.

Major Sources of Formaldehyde in Homes

Pressed-wood products: plywood, paneling, particleboard, fiberboard
Furniture and furnishings made with pressed wood products
Carpet
Glues and adhesives
Permanent press fabrics
Paper products
Paint and varnish
Burning of oil, gas, kerosene, coal, or wood
Cigarette smoke
Adhesives
Foam insulation
Wallcoverings

Health Effects of Formaldehyde

Exposure to formaldehyde can cause both short-term and long-term health effects. General symptoms include:

Eye, nose, throat, and skin irritation
Wheezing and coughing
Asthma attacks
Fatigue
Skin rashes
Severe allergic reactions

Long-term exposure to high levels of formaldehyde is associated with an increased risk of cancer. The National Cancer Institute (NCI) determined that exposure to formaldehyde may cause leukemia, particularly myeloid leukemia, in humans.

How an Air Purifier Can Remove VOCs and Formaldehyde

Traditional air purifiers are only moderately effective at removing VOCs and formaldehyde from the air. The most effective type of air purifier for removing these pollutants uses activated carbon filtration. Activated carbon has a massive surface area due to its porous structure which allows it to adsorb and trap VOCs, formaldehyde, and other gaseous pollutants.

Other effective technologies include:

Photocatalytic Oxidation (PCO) – Uses UV light and a titanium dioxide coated filter to oxidize organic pollutants and convert them into harmless compounds like carbon dioxide and water.
PECO – A proprietary technology that uses free radicals generated by UV light to oxidize pollutants.

An air purifier combining activated carbon with PCO or PECO will provide the most thorough removal of VOCs and formaldehyde.

Do HEPA Air Purifiers Really Work? The Truth Revealed

Do HEPA air purifiers really work? The truth revealed

HEPA (High Efficiency Particulate Air) air purifiers can be highly effective at removing harmful particles from the air when used properly. HEPA filters are designed to capture 99.97% of particles sized 0.3 microns or larger, including dust, pollen, mold spores, bacteria, and more. Here’s a closer look at how HEPA air purifiers work and why they can make a real difference in indoor air quality.

How HEPA Air Purifiers Work

HEPA air purifiers draw air through a fine mesh filter that traps particles as air passes through. The filters have dense folds of fiberglass or synthetic material that particles cannot penetrate. As air is forced through these tightly packed layers, particles are captured on the fibers.

Only air purifiers certified to meet strict HEPA standards can remove 99.97% of 0.3-micron particles in a single pass. True HEPA filters exceed the 300 Grade standard defined by the Institute of Environmental Sciences and Technology.

Why Size Matters

HEPA filters are designed to capture the smallest particles that can be inhaled deep into the lungs. Research shows that exposure to fine particulate matter 2.5 microns or smaller (PM2.5) poses the greatest health risks.

PM2.5 refers to particles 30 times smaller than the width of a human hair. These minuscule particles can slip past our body’s defenses and penetrate deep into the lungs, entering the bloodstream. HEPA filtration targets these harmful tiny particles.

Effectiveness for Allergies and Asthma

HEPA air purifiers excel at removing allergens like pollen, mold spores, pet dander, and dust mites. By eliminating these triggers from the air, HEPA filters can provide relief for allergy and asthma sufferers.

A study published in the Annals of Allergy, Asthma & Immunology demonstrated that HEPA air cleaners dramatically reduced asthma symptoms for children sensitive to dust mites. The air purifiers lowered asthma medication use by 79%.

Capturing Viruses, Bacteria, and More

In addition to allergens and asthma triggers, HEPA filters capture airborne viruses, bacteria, smoke, and other bioaerosols. HEPA air purifiers installed in hospitals have been shown to reduce infections in high-risk areas.

During wildfires or in areas with high pollution, HEPA filters can remove hazardous fine particles from smoke and smog. The ultra-fine particle trapping abilities make these filters helpful for protecting indoor air quality.

Considerations for Effectiveness

To realize the full benefits of HEPA filtration, consider these factors:

Room size – Choose an appropriately sized unit for the room.
Air changes per hour (ACH) – Look for a clean air delivery rate (CADR) that will filter the room’s air at least 2-4 times per hour.
Proper maintenance – Replace filters as needed to maintain performance.
Whole-home systems – For maximum air purification, install HEPA filters in central HVAC systems.

The Bottom Line

HEPA air purifiers absolutely can make a noticeable difference in removing allergens, pollutants, viruses, and ultrafine particles from the air when properly matched to room size and well maintained. By trapping the smallest respirable particles, HEPA filters can significantly improve indoor air quality.

The Hidden Dangers of Ionized Air Purifiers

Ionized air purifiers have become increasingly popular in recent years as people look for ways to improve the air quality in their homes. While these devices do help reduce dust, dander, and other pollutants, some studies suggest they may also create potentially harmful byproducts. In this in-depth article, we’ll examine the side effects of ionized air purifiers and help you make an informed decision about using one in your home.

How Ionized Air Purifiers Work

Ionized air purifiers use a process called corona discharge to charge airborne particles with negative ions. These charged particles then cling to surfaces like walls, floors, curtains, and tabletops, causing the particles to drop out of the air. This can quickly reduce the number of irritants like dust and pet dander floating in the indoor air.

To generate these ions, ionized purifiers use thin electrically charged plates which alter the charge of air molecules as they pass by. The now charged negative ions then exit the purifier and attach themselves to the pollutant particles.

The Benefits of Ionized Air Purifiers

There are several potential benefits that make ionized air purifiers popular:

They efficiently remove very small particles from the air, including some viruses and bacteria.
They can quickly improve perceived air quality as particles drop out of the air rapidly.
They do not require expensive HEPA filters that need regular replacement.
They are often inexpensive to purchase compared to other types of air purifiers.

For people who want an affordable way to reduce airborne allergens and particles, ionized purifiers can seem like an excellent solution.

Potential Ionized Air Purifier Side Effects

However, ionized air purifiers also have some significant drawbacks and potential side effects that consumers should be aware of.

Ozone Generation

One major concern is that some ionized purifiers produce ozone gas, a lung irritant that can cause multiple symptoms. Ozone is created as a byproduct of the ionization process. While inhaling small amounts of ozone likely won’t cause noticeable issues in most people, prolonged exposure can create the following problems:

Chest pain, coughing, and shortness of breath
Reduced lung function
Aggravation of conditions like asthma and bronchitis
Increased oxidative stress, which may accelerate aging and disease

Children, the elderly, and those with chronic respiratory conditions or weakened immune systems face the greatest risks from ozone exposure. Even in healthy adults, breathing ozone over time can potentially cause permanent lung damage.

Production of Ultrafine Particles

In addition to ozone, some research indicates ionizing purifiers also generate ultrafine particles that are small enough to penetrate deep into the lungs. These tiny particles then deposit in the airways and alveoli, potentially causing inflammation or other lung changes. Studies have linked long-term exposure to fine particulate matter with:

Declines in lung function
Development of asthma
Exacerbation of COPD
Increased respiratory infections
Higher risk of lung cancer

While more research is needed, these early findings suggest ionizing technology may create new indoor air pollution while reducing other particles. This unintended side effect could pose health risks, especially for sensitive groups.

Charged Particle Fallout

As mentioned earlier, ionized air purifiers work by charging particles which then cling to surfaces like walls, floors, and other objects. While this removes irritants from the air, it deposits them onto surfaces within a room.

Some studies have found this can significantly increase allergen exposure in a home. The charged particles hold very tightly to surfaces and objects, making them difficult to remove with casual cleaning. Vacuuming, dusting, and washing may not be enough to fully eliminate the layered deposits. So while the air seems cleaner, allergen exposure continues through regular contact with contaminated surfaces.

Safer Alternatives to Ionized Air Purifiers

Given the potential ionized air purifier side effects, many consumers understandably have concerns about using these devices. Fortunately, there are several effective and safer alternatives:

HEPA Air Purifiers

HEPA (high efficiency particulate air) filters can remove up to 99.97% of particles sized 0.3 microns and larger. This includes dust, pollen, pet dander, mold spores, bacteria, and some viruses. Unlike ionizers, HEPA purifiers use simple mechanical filtration that doesn’t generate any dangerous byproducts. They are highly effective at reducing both airborne particles and surface allergens in a space.

Activated Carbon Purifiers

Activated carbon filters adsorb gaseous pollutants like volatile organic compounds (VOCs), smoke, and fumes. Using a purifier with both HEPA and carbon filtration provides protection against particulate matter, gases, and odors. This dual approach helps ensure you’re breathing the cleanest air possible.

Photocatalytic Oxidation

Photocatalytic oxidation (PCO) uses UV light along with a titanium dioxide coated filter to break down organic pollutants. PCO can destroy a wide range of gases, bacteria, viruses, and VOCs at the microscopic level through an oxidation reaction. Combining PCO with HEPA filtration offers comprehensive whole-home air purification.

Air purifiers using these alternative technologies have been shown to effectively clean the air without generating any concerning byproducts like ozone or ultrafine particles.

Recommendations for Safer Use

If you already own an ionized air purifier or are considering purchasing one, there are several steps you can take to reduce potential side effects:

Only run the ionizer when necessary – don’t leave it on 24/7.
Follow the manufacturer’s maintenance guidelines to keep the plates clean for lower ozone production.
Place the purifier away from areas where people spend a lot of time, like bedrooms.
Install an ozone detector to monitor levels.
Use the ionizer along with HEPA filtration to capture any particles generated.
Consider using an alternative purification technology instead.

Taking these precautions can help minimize exposure to ozone and any other byproducts produced by your ionized air purifier.

The Bottom Line

Ionized air purifiers certainly have benefits in terms of reducing airborne allergens and particles. However, the potential risks from ozone production, ultrafine particles, and surface contaminants have raised health concerns. There are safer, non-ionizing alternatives available that avoid these side effects. If you do choose an ionizer, take steps to reduce byproduct exposure, especially for vulnerable groups like children and those with respiratory conditions.

With a better understanding of the pros and cons, you can make an informed decision about the best air purification options for your home and health.

Frequently Asked Questions

Are ionized air purifiers bad for your health?

Some studies have raised concerns about potential adverse health effects from ionized air purifiers, especially for sensitive groups. Ozone and ultrafine particle production may cause issues when inhaled over long periods. Those with lung conditions should exercise caution with ionizers.

Do ionized air purifiers put out dirty electricity?

Ionizers may put out small amounts of electrostatic discharge or electromagnetic radiation. Whether this “dirty electricity” causes problems is still under investigation. The FDA has not found significant health effects but recommends keeping ionizers away from electronic medical devices.

Should you leave an ionized air purifier on all the time?

It’s best not to run ionized purifiers continuously – the longer they operate, the more ozone and particles may be generated. Use intermittent operation or an on/off timer. Also place the ionizer far from high-traffic areas to limit exposure.

Do ionized air purifiers produce carbon monoxide?

No, ionizers do not create carbon monoxide, which is an odorless gas produced by incomplete combustion. Ionized purifiers may generate ozone and ultrafine particles, but not carbon monoxide.

Can ionized air purifiers kill birds?

There are some reports of ionizers harming small birds like canaries. The high ozone levels may be toxic to birds in enclosed spaces. Keep ionizers away from birdcages and avoid use in rooms where birds live.

Do negative ions give you headaches?

Some people do report headaches, nausea, dizziness or fatigue from high exposure to negative ions. Manufacturers claim these symptoms will subside as your body acclimates. But negative effects may indicate you’re sensitive and should limit use.

Are ionized air purifiers worth the risk?

For most people, the potential risks of ozone exposure and lung irritation outweigh the benefits provided by ionizers. Safer non-ionizing alternatives like HEPA air purifiers provide cleaner air without side effects. Carefully consider if the risks are worth any perceived benefits.

How Big of an Air Purifier Do I Need? A Complete Guide

The size of the air purifier you need depends on the size of the room you want to purify. As a general rule, you’ll want an air purifier that can circulate air through the room’s volume at least 2-4 times per hour. Here’s a more detailed look at how to determine the right air purifier size for your space:

Step 1: Measure the Room’s Dimensions

First, measure the length, width, and height of the room in feet to determine its total volume in cubic feet. An easy formula is:

Length x Width x Height = Volume in cubic feet

For example, a room that’s 12 ft long x 10 ft wide with 8 ft ceilings would be:

12 x 10 x 8 = 960 cubic feet

Step 2: Find the ACH Rating

Next, look at the product specifications for the air purifier’s Air Changes per Hour (ACH) rating. This tells you how many times it can circulate the air in a given space per hour.

For smoke, allergens, and light odors, look for a minimum 2-4 ACH rating. For strong smells like cooking fumes or wildfire smoke, look for 4-6 ACH.

Step 3: Match Room Size to ACH

Match the room’s cubic footage to an air purifier with an appropriate ACH. Here are some general guidelines:

Room Size	Minimum ACH Needed
100 sq ft	2 ACH (can circulate 200 cu ft per hour)
200 sq ft	2 ACH (can circulate 400 cu ft per hour)
500 sq ft	4 ACH (can circulate 2,000 cu ft per hour)
1000 sq ft	4 ACH (can circulate 4,000 cu ft per hour)

For example, that 960 cu ft room from earlier would need an air purifier with at least a 4 ACH rating, able to circulate 3,840 cu ft per hour.

Other Considerations

Room layout, ceiling height, and the type of pollutant can also impact the ideal size:

Prioritize higher ACH for open floor plans
Tall ceilings may need stronger circulation
Cooking, wildfire smoke, and viruses need 4-6+ ACH

Getting the right air purifier size for your space ensures it can actually clean the air effectively. Oversized units will waste energy while undersized ones can’t fully purify the air.

Frequently Asked Questions

1. Do multiple rooms need multiple air purifiers?

Yes, you’ll need one air purifier per room you want to purify. Air purifiers only filter air within a single enclosed space.

2. Where should I place the air purifier in a room?

Put the air purifier centrally in the room and at least a few feet from walls or other obstructions. Avoid corners or alcoves for maximum air circulation.

3. How do I measure a room’s cubic footage?

Measure the room’s length, width, and height in feet then multiply them together to get cubic footage. An online calculator can also help determine cubic feet if the room has an irregular shape.

4. Can an air purifier be too powerful?

Overpowered air purifiers are not necessarily better. Excessively strong fans can stir up pollutants and create noise. Find an air purifier matched to the room’s size.

5. Do air purifiers use a lot of electricity?

Air purifiers vary in energy use, but an efficient unit sized for the space generally costs just pennies per day to run. Larger and oversized purifiers use more electricity.

6. How often should I change the filter?

Most filters should be changed every 6-12 months. Check your model’s specs, as some have indicators to alert you when the filter needs replacement.

7. Can air purifiers reduce airborne viruses?

Do Air Purifiers Give Off Radiation? Debunking the Myth

Do air purifiers give off radiation? The truth revealed

Air purifiers do not give off harmful radiation. While all electronic devices emit some electromagnetic radiation, air purifiers operate at levels well below safety thresholds and do not pose a health risk.

How air purifiers work

Air purifiers use filters and fans to remove pollutants from the air. Some models may also use ultraviolet light or negative ions to help clean the air. But none of these technologies emit dangerous radiation.

Types of air purifiers

Type	How it Works
HEPA filter	Traps particles like dust, pollen, and smoke
Activated carbon filter	Absorbs gases like VOCs and odors
UV light	Kills mold, bacteria, and viruses
Ionizer	Emits negative ions to attract particles

Do air purifiers emit radiation?

Some air purifiers use UV light or ionizers that could theoretically emit radiation. However, they operate well below hazard levels.

UV light air purifiers

UV light air purifiers contain a UV-C light bulb that emits short-wave ultraviolet radiation. This UV light kills microbes like mold, bacteria, and viruses by damaging their DNA and preventing them from reproducing. However, the UV light is contained inside the sealed purifier where people cannot be exposed to it. UV air purifiers do not leak harmful radiation.

Ionizer air purifiers

Ionizer air purifiers emit negative ions, which are oxygen molecules with an extra electron. These ions cause particles like dust and pollen to stick together and precipitate out of the air. Ionizers do emit some ozone, a form of oxygen that can irritate lungs at high levels. However, ionizers sold today must meet strict ozone emission standards of less than 50 parts per billion.

Are air purifiers safe?

Yes, air purifiers are completely safe when used as directed. All air purifiers sold in the US must meet Electrical Safety standards from organizations like UL and ETL. This includes limits on the electromagnetic radiation they can emit. While air purifiers give off some radiation inherent to all electronics, it is far below amounts that could impact human health.

Frequently Asked Questions

Do HEPA air purifiers emit radiation?

No. HEPA air purifiers use fans and filters to clean the air. They do not emit any harmful radiation.

Do ionizer air purifiers give you cancer?

No. Ionizer air purifiers emit ozone, but at levels far below safety limits when compliant with regulations. There is no evidence ionizers cause cancer.

Is it safe to sit near an air purifier?

Yes. Air purifiers produce less EMF radiation than other common household electronics like televisions, cell phones, and WiFi routers. You can safely sit or sleep near an air purifier without risk.

Do UV air purifiers leak UV light?

No. The UV light is fully contained inside a sealed chamber. No UV radiation can escape the air purifier.

Should you leave an air purifier on all night?

Yes, many air purifiers are designed to run 24/7. Just follow the manufacturer’s instructions. Letting it run overnight can continuously clean the air while you sleep.

Do air purifiers reduce dust?

Yes. Air purifiers efficiently remove dust, dander, pollen, and other airborne particles from the room. This helps reduce settled dust over time.

Do air purifiers help with allergies?

Yes. By removing allergens like pollen and pet dander, air purifiers can provide relief for allergy sufferers.

The bottom line

Air purifiers do not emit harmful radiation. While they generate low levels of EMF inherent to all electronics, it is not enough to impact health. Air purifiers utilize contained UV light and regulated ozone emission ionizers. When used as directed, air purifiers are completely safe.

Do HEPA Filters Actually Remove Viruses from the Air We Breathe?

Do HEPA Filters Remove Viruses?

With illnesses like COVID-19 and the flu spreading through the air, many people wonder if using a HEPA filter can help protect them from airborne viruses. HEPA filtration can capture some viral particles, but it should not be relied on as a complete solution. This article will examine how effective HEPA filters are against viruses and what precautions are still needed even when using these specialized filters.

What Are HEPA Filters and How Do They Work?

HEPA stands for “high efficiency particulate air.” To qualify as true HEPA, a filter must remove a minimum of 99.97% of particles that are 0.3 microns in size during testing. This capability makes HEPA filters useful against viruses, but they have limitations.

Particle Size	Removal Efficiency
0.3 microns	99.97%
0.1 microns	99.99%

HEPA filters capture particles through a combination of techniques:

Interception – particles following the air flow path collide with filter fibers and stick.
Impaction – particles too large to avoid fibers get trapped in them.
Diffusion – smallest particles bounce around and adhere to fibers.
Electrostatic attraction – filter materials attract and hold particles.

This mesh of dense fibers catches even very tiny particles like viruses as air passes through. Better filters have more uniform fibers to maximize particle capture.

Can HEPA Filters Remove Viruses Like COVID-19 and Flu?

HEPA filters can capture airborne viral particles, including SARS-CoV-2 (the virus causing COVID-19) and influenza. However, viruses present some challenges:

Small size – Many viruses are smaller than 0.3 microns. HEPA filters are less effective on these tiny particles.
Aerosol transmission – Viruses can travel in aerosols, remaining airborne longer than larger droplets.
Infectious dose – It may take only a few virus particles to cause infection and illness.

Despite these difficulties, HEPA filters still significantly reduce airborne viruses. Studies estimate they remove over 99% of virus-containing droplets and particles. Portable HEPA air purifiers can supplement HVAC filters to improve air cleaning throughout a building.

HEPA Filter Limitations Against Viruses

While HEPA filters capture most viral particles, they cannot completely eliminate the risk of airborne transmission:

Not 100% effective – A small number of viruses can pass through, especially smallest ones.
Bypass – Unfiltered air can bypass filter if not properly sealed.
Saturation – Filters get overloaded as particles accumulate.
Recirculation – Filters do not remove viruses already present in the air.

Additionally, viruses deposited on the filter can remain infectious for hours to days depending on the specific type. Proper handling and disposal is important to avoid transmission from used filters.

Virus	Survival Time on HEPA Filter
SARS-CoV-1	72 hours
MS2 bacteriophage	8-12 hours

Best Practices for HEPA Filtration Against Viruses

While HEPA filters have limitations, they remain a useful part of a complete infection control strategy when implemented properly:

Right filter ratings – Choose true HEPA rated filters, which are 99.97% efficient at 0.3 microns.
Combined ventilation – Supplement with outdoor air intake and exhaust ventilation.
Portable purifiers – Use HEPA purifiers to boost filtration in high-risk areas.
Monitor performance – Check differential pressure across filter to detect any damage or leaks.
Change filters – Replace per manufacturer instructions, typically every 6-12 months.
Proper installation – Ensure tight filter fit to prevent bypass leakage.
Control humidity – Keep relative humidity below 65% to avoid viral particle aggregation.

In critical spaces like hospitals, the highest-rated HEPA filters along with supplemental disinfection techniques are recommended. Commercial buildings should consult HVAC professionals on selecting appropriate filtration levels.

Other Precautions to Take with HEPA Filtration

HEPA filters reduce airborne viruses, but cannot entirely prevent transmission on their own. Even venues using HEPA filters need additional precautions like:

Face masks – Wear tight-fitting masks like N95s, KN95s, or KF94s.
Social distancing – Keep at least 6 feet between people.
Occupancy limits – Reduce density in indoor spaces.
Ventilation – Bring in outdoor air; avoid stagnant recirculation.
Surface cleaning – Disinfect high-touch surfaces frequently.
Hand hygiene – Wash hands thoroughly and often.
Respiratory etiquette – Cover coughs and sneezes.

A “Swiss cheese” model with layered interventions will reduce overall transmission risks more than any single measure alone. HEPA filters serve as an important component when combined with additional evidence-based precautions.

Conclusion

HEPA filtration can capture most airborne viruses in a space, lowering infection risk. However, it has limitations and should not be the sole protective measure. True HEPA filters, properly installed and maintained, remain useful as part of a multifaceted infection control approach. Supplementing with portable purifiers, adequate ventilation, and other hygiene practices is key for protecting public health against illnesses like COVID-19 or influenza.
