An In-Depth Guide to the Different Types of Air Purifiers

I. Introduction

Indoor air quality has become an increasing concern in recent years. The EPA estimates that indoor air is 2 to 5 times more polluted than outdoor air. Poor indoor air quality can lead to various health issues like allergies, asthma, and chemical sensitivities.

Air purifiers provide an effective solution for cleaning the air inside your home. They work by filtering out pollutants like dust, pollen, mold, bacteria, pet dander, smoke, VOCs (volatile organic compounds), and more.

There are several different technologies used in air purifiers:

• HEPA (High Efficiency Particulate Air) filters – Most common type of air purifier filter, can capture 99.97% of particles 0.3 microns in size.
• Activated carbon filters – Absorb gases, odors, smoke, VOCs, and chemicals.
• UV-C light – Uses ultraviolet light to kill germs like bacteria and viruses.
• Ionic filters – Generate negative ions to attract and trap pollutant particles.
• Ozone generators – Produce ozone gas to oxidize and destroy contaminants.

This guide provides an in-depth look at how each type of air purifier works, their pros and cons, and popular options available.

Type	Pros	Cons
HEPA	Removes 99.97% of particles; great for allergies	No gas/odor removal; filter needs replacing
Activated Carbon	Eliminates odors and gases	Doesn’t capture particles; filter needs replacing
UV-C	Kills mold, bacteria, viruses	Doesn’t remove particles or gases
Ionic	Inexpensive; no filter replacing	Limited particle removal; potential ozone
Ozone Generator	Not recommended due to health risks

II. HEPA Air Purifiers

What is a HEPA Filter?

HEPA stands for High Efficiency Particulate Air. HEPA filters are designed to remove tiny particles from the air that can be harmful to breathe.

Particles that are 0.3 microns or larger are trapped with 99.97% efficiency. For reference, a human hair is about 100 microns wide. Common indoor air pollutants in this size range include:

• Dust
• Pollen
• Pet dander
• Mold spores
• Bacteria
• Smoke particles
• PM2.5 particulate matter

HEPA filters utilize a dense mesh of randomly arranged fiberglass fibers. As air passes through, particles are captured and retained in the filter. This removes them from the circulating air.

Pros of HEPA Air Purifiers

• Proven effectiveness – Extensively tested to meet strict performance standards. Government agencies like the Department of Energy rely on HEPA filtration.
• Removes most common allergens – HEPA is excellent at trapping dust, pollen, pet dander, mold spores and other particulate allergens. This helps reduce allergy and asthma symptoms.
• No byproducts or emissions – HEPA filters simply capture contaminants without producing any ozone or other chemicals. They don’t generate any secondary pollution.

Cons of HEPA Air Purifiers

• Doesn’t remove odors or gases – HEPA filters cannot absorb VOCs, smoke smells, chemical fumes and other gaseous pollutants. Need added activated carbon filter for this.
• Can be noisy – The fans required to pull air through dense HEPA filters can generate noise levels of 50 dB or more on higher speed settings.
• Replacement filters are required – HEPA filters become clogged after 6-12 months depending on use. Replacement filters can cost $50 to over $100.
• Larger particles first – HEPA is least efficient at capturing the smallest particles between 0.1 – 0.3 microns. Larger particles tend to clog the filter first.

Popular HEPA Air Purifier Models

• Winix 5500-2 – This is a leading air purifier for allergy and asthma sufferers. It includes true HEPA filtration, washable pre-filters, and activated carbon for odors.

III. Activated Carbon Air Purifiers

What is Activated Carbon?

Activated carbon is a highly porous material made from carbon. It has an incredibly large surface area that allows it to absorb and trap gases, chemicals and odors.

The “activation” process expands the pores and increases the surface area dramatically, creating an adsorbent material. Activated carbon is used in water filters, automotive cabin air filters, and of course, air purifiers.

In air purifiers, a layer of activated carbon is added to filtration systems. As air passes over the carbon, the pores capture VOC gases, cigarette smoke, cooking odors, pet odors, paint fumes, and other airborne chemicals.

Activated carbon removes these gaseous pollutants that standard HEPA filters cannot. The carbon also helps neutralize odors by adsorbing the molecules that cause smelly air.

Pros of Activated Carbon Air Purifiers

• Eliminates odors – Excellent at removing cooking smells, pet odors, cigar and cigarette smoke, musty smells and other odors from the air.
• Absorbs gases & VOCs – Takes out fumes from adhesives, paints, pesticides, cleaners and other chemical sources. Reduces indoor air pollution.
• Quiet operation – Activated carbon filters have low air resistance so fans don’t need to work as hard. Units run more quietly as a result.
• Often combined with HEPA – Many air purifiers combine HEPA filtration with activated carbon. This gives you the best of both worlds.

Cons of Activated Carbon Air Purifiers

• Doesn’t remove particles – Activated carbon only filters gases and odors. To remove dust, dander, etc. it needs to be paired with a HEPA filter.
• ** eventual replacement** – The carbon’s absorption sites get filled over time and it stops working. Replacement filters needed every 6-12 months.
• Not effective for some VOCs – Doesn’t work well for formaldehyde and other small molecular VOCs. Significant sources may require dedicated gas absorber filter.
• Can release trapped odors – Gas molecules trapped in the carbon can escape back into the air later. Periodic regeneration is required.

Popular Activated Carbon Air Purifier Models

• Austin Air Healthmate Standard – A simple yet high performing unit focused on activated carbon filtration. Includes 15 lbs. of carbon and HEPA filter.
• IQAir GC MultiGas – Commercial grade system designed for chemical sensitivity and VOC removal. Has 9 lbs. of activated carbon and HyperHEPA filtration.

• Winix 5500-2 – This popular model includes activated carbon pellets to reduce odors along with true HEPA particle filtration.
• Honeywell HPA300 – An affordable room air purifier with a washable carbon pre-filter and HEPA filter for reduced operating costs.

IV. UV-C Air Purifiers

How Does UV-C Technology Work?

UV-C air purifiers use short-wavelength ultraviolet light to kill or deactivate microorganisms like bacteria, viruses, and mold.

UV-C radiation damages the DNA and RNA of these organisms, rendering them unable to reproduce or function. This creates a germicidal effect without the use of chemical biocides.

Air purifiers emit UV-C light into an internal chamber that the airflow passes through. This exposure kills mold spores, bacteria, viruses and other biological contaminants in the air.

Some UV-C systems also utilize titanium dioxide filters that are activated by the UV light. This catalyzes oxidation reactions that destroy VOCs and odors.

Pros of UV-C Air Purifiers

• Attacks biological pollutants – UV light has been proven effective at neutralizing mold, bacteria, viruses, and other living microbiological contaminants.
• No filter changes required – Since UV-C works by irradiation rather than filtration, there are no filters to replace. Reduces operating costs.
• Chemical free purification – UV purification is achieved without using ozone or other potentially hazardous chemicals.
• Odor reduction capability – Units with TiO2 filters also help remove VOCs and smoke odors as air passes through the UV chamber.

Cons of UV-C Air Purifiers

• Doesn’t remove particulate matter – UV light has no effect on dust, pollen, pet dander and other non-living particles. HEPA filter still needed for these.
• Exposure risks – Direct UV exposure can damage skin and eyes. The irradiation chambers must be shielded to prevent UV rays leaking out. Cheaper units may have inadequate shields.
• Limited air flow – The irradiation chamber and shields restrict airflow, reducing CADR ratings compared to HEPA-only air purifiers. Not suitable for large spaces.
• Bulb replacement – UV-C bulbs lose intensity over time and need replacement every 2-3 years to maintain effectiveness.

Popular UV-C Air Purifier Models

• Alen BreatheSmart Flex – A customizable unit with HEPA-FreshPlus filter and UV-C sanitization chamber with 10 UV bulbs.
• **Geniani Aircare – **Combines a True HEPA filter with UV-C light chamber containing 3 UV bulbs to kill germs.

• Envion Therapure TPP240 – Compact UV tower unit good for smaller rooms. Has UV-C, HEPA filter, and optional ionizer.

V. Ionic Air Purifiers

How Do Ionic Air Purifiers Work?

Ionic air purifiers work by charging air molecules and pollutants with electrons using an electrostatic charge field. This generates positive and negative ions that are released into the passing air stream.

The extra electrons attach to particles like dust, dander, pollen, mold and cigarette smoke. This gives them a negative charge so they are attracted to the positively charged collection plates inside the air purifier.

This electrostatic process causes the charged particles to clump together and become large enough to be captured on the plates. Some ions exit the unit to attach to out-of-reach particles as well.

Pros of Ionic Air Purifiers

• Inexpensive – Ionic purifiers are one of the most budget-friendly options since they don’t require expensive HEPA filters. Lower operating costs.
• Silent operation – With no fans or mechanical filters, most ionic purifiers run completely silently.
• Ozone free – Many ionizers now use needlepoint ion generation which does not produce dangerous ozone gas as a byproduct. Look for “ozone free” models.
• No maintenance – Ionic filters don’t need replacement like HEPA filters. Just occasional cleaning of collection plates.

Cons of Ionic Air Purifiers

• Limited particle removal – Ionic purifiers only remove about 30% of larger particles and 10% of fine particles. Not effective enough to be a sole air cleaner for many situations.
• Dirty plates – Collection plates become coated with particles and need frequent cleaning to remain effective. Plates may need weekly cleaning.
• Potential ozone production – Poor quality ionizers, especially older ones using corona discharge, can generate hazardous levels of lung-damaging ozone.
• Charged particle emissions – Some negatively charged particles may get re-released into the room air instead of being collected. There are health concerns over effects of inhaling charged particles.

Popular Ionic Air Purifier Models

• Winix Plasmawave 5300 – A newer unit that uses ozone-safe needlepoint plasmawave ion generation combined with basic carbon filtration.
• Oion Technologies B-1000 – Compact ozone-free ionizer good for travel. Uses radio-frequency transmitted ions to charge particles.
• Pure Enrichment PureZone – Budget ionizer and HEPA filter combination unit. Plates need frequent cleaning.
• Envion IonAir – Retro-looking ionizer tower designed for smaller rooms. Has 3 fan speed settings and optional UV-C.
• Sharper Image Ionic Pro – Oscillating compact ionic air purifier with touch controls and PM2.5 particle sensor.

VI. Ozone Air Purifiers

What is Ozone and How Do Ozone Generators Work?

Ozone is an unstable toxic gas made up of three oxygen atoms (O3). While ozone exists naturally in the upper atmosphere, at ground level it is classified as an air pollutant.

Ozone generators produce ozone artificially using corona discharge or UV light methods. The strong oxidizing power of the O3 molecules destroys bacteria and odors. But it also damages lung tissue lining when inhaled.

Most health organizations recommend avoiding ozone generators since potential harms outweigh benefits. Ozone does not effectively clean and purge indoor spaces of pollutants either, as was once believed.

Pros of Ozone Air Purifiers

• Attacks odors – The oxidizing potential of ozone may have some effectiveness at removing stubborn odors that linger even after cleaning.
• Inexpensive – Basic ozone generators are cheap since they have no filters and few parts.

Cons of Ozone Air Purifiers

• Health hazards – Multiple studies have shown health risks of ozone, especially for children and those with asthma or respiratory conditions. Short term effects include chest pains, coughing, throat irritation and lung damage.
• No particulate filtration – Ozone does not remove dust, pollen, pet dander, mold and other common airborne particles.
• Ineffective pollution removal – Ozone has low reactivity with many chemicals like VOC gases. It does not cleanse rooms of pollutants as marketed.
• Property damage potential – Ozone can degrade rubber, plastic and fabrics, causing damage to belongings. Many materials are not ozone resistant.

Examples of Ozone Generator Air Purifiers

• Ozone generators are not commonly found anymore due to health concerns, but a few models still exist:
• EcoQuest Fresh Air – Uses coronal discharge to produce ozone. EcoQuest claims their “activated oxygen” process is safe but many health agencies disagree.
• OdorStop OS2500 – An industrial style ozone generator that creates very high ozone concentrations advertised to remove smoke odor. Too high for safe residential use.
• Airthereal MA10K-PRO – Despite marketing as an ionizer, it uses UV bulbs to generate ozone rather than the safer needlepoint method.
• Ecozone Ozone Generator – Among the most affordable ozone machines but puts out an alarming amount of ozone at up to 7,000 mg/hr.

VII. Conclusion

There are a variety of air purifier technologies available to improve indoor air quality:

• HEPA air purifiers are the most effective at removing airborne particles like dust, dander and allergens.
• Activated carbon air purifiers excel at adsorbing odors, gases and VOCs that HEPA filters miss.

Choosing the Best HEPA Filters for Smoke

Introduction

HEPA filters are an effective way to improve indoor air quality by capturing harmful particles and pollutants. HEPA, which stands for high-efficiency particulate air, is a type of mechanical air filter that forces air through a fine mesh and traps particles as small as 0.3 microns. This includes smoke, dust, pollen, pet dander, mold spores, and bacteria.

HEPA filters work by pulling air through a tightly woven mat of glass fibers or a similar synthetic material. As the air passes through, pollutant particles get stuck on the fibers. The mesh is so fine that it can capture over 99.97% of particles 0.3 microns or larger. This means HEPA filters excel at trapping the tiny particles in smoke and other irritants that can cause health issues.

Using HEPA filters can provide several benefits when dealing with smoke:

• Improve indoor air quality by reducing smoke particles, ash, and associated odors
• Lower the health risks from smoke inhalation including eye, nose and lung irritation
• Help prevent particles from settling on surfaces and fabrics throughout the home
• Eliminate persistent smoky smells from fabrics, carpets, walls and other household items

The aim of this article is to review some of the best HEPA filters for smoke available today, compare their features and performance, and provide tips on choosing the right one for your needs. We will examine the differences between standard and true HEPA filters, the importance of combining HEPA with activated carbon, key features to look for, and recommend top-rated models on the market. With the right HEPA filter, you can effectively remove smoke from the air and enjoy cleaner, healthier indoor air quality.

How to Reduce Smoke Exposure at Home

When wildfires or other sources are causing smoky outdoor air, the smoke can easily infiltrate into your home. While HEPA filters are extremely effective at trapping smoke particles, there are also some other steps you can take to reduce smoke exposure at home:

Use Air Purifiers with HEPA Filters

• Invest in an air purifier for your home that uses true HEPA filtration. This will maximize removal of fine smoke particles.
• Choose an air purifier with a high clean air delivery rate (CADR) specifically for smoke removal (200 cfm or higher recommended).
• Place the air purifier in rooms where you spend a lot of time with the doors closed, such as bedrooms. Run it continuously on the highest fan setting during smoke events.

Seal Windows, Doors and Vents

• Use weather stripping or draft blockers to seal any gaps or cracks around windows and external doors. This prevents smoke from seeping into the home.
• Make sure all vents and openings are closed (fireplace dampers, dryer vents, etc).
• Operate the air conditioner or central heating system with recirculated indoor air rather than drawing in outdoor air.

Avoid Additional Indoor Pollutants

• Avoid activities like smoking, burning candles or incense, frying foods, and vacuuming that can generate additional indoor pollutants.
• Consider avoiding ozone generators or ionic air purifiers, as they can produce harmful byproducts that irritate the lungs.

Create a Clean Room

• Set up a designated clean room in your home with a portable air purifier and enhanced seals around windows and doors. Spend most of your time in this space when smoke levels are high outdoors.

Using air purifiers effectively along with other methods can significantly reduce smoke particles indoors and create cleaner air shelters even when outdoor air quality is poor.

Differences Between Standard and True HEPA Filters

There are some key differences between standard HEPA filters and true HEPA filters that impact their effectiveness at removing smoke particles from the air:

Particle Removal Efficiency

• Standard HEPA filters are designed to capture at least 99.97% of particles 0.3 microns in size.
• True HEPA filters capture 99.99% or more of particles 0.1 microns and larger.

Materials and Construction

• Standard HEPA filters often use loosely packed glass fibers.
• True HEPA filters use densely packed fibers and additional components to optimize air flow and maximize particle capture.

Smoke Particle Size

• The majority of smoke particles generated by fires fall within the 0.01 to 1 micron size range.
• This means true HEPA filters will capture more smoke particles compared to standard HEPA filters.

In summary, true HEPA filters are superior at trapping the fine particles present in smoke thanks to their enhanced design and materials. While standard HEPA filters still perform well, true HEPA is recommended for optimal smoke removal.

Using Activated Carbon/Charcoal Filters for Smoke Odors and VOCs

HEPA filtration excels at removing smoke particles and ash from the air, but cannot eliminate associated odors or gaseous pollutants known as volatile organic compounds (VOCs).

That’s where using activated carbon or charcoal filters comes in. These work through a process called adsorption:

• Activated carbon/charcoal filters contain a highly porous media with an extremely large surface area.
• As air passes through, smoke odors, VOCs, and other gaseous pollutants are trapped on the surface of the carbon through chemical attractions.
• This effectively removes them from the air without generating any byproducts.

The large surface area packed into a small carbon filter allows it to adsorb large volumes of gaseous contaminants.

Some key benefits of activated carbon/charcoal filtration for smoke odors and VOCs:

• Eliminate smoky or burnt smells from the air
• Remove irritating VOCs like formaldehyde that can cause eye, nose and throat irritation
• Prevent residual odors from being absorbed into walls, carpets, furniture and other household items
• Carbon filters don’t generate any byproducts or harmful side effects

Look for an air purifier that combines both true HEPA and activated carbon or charcoal filtration for comprehensive smoke removal. The pairing maximizes removal of all particle sizes as well as eliminates unpleasant odors and VOC exposure.

While standard HEPA filters perform well for most residential needs, upgraded versions provide longer lasting filtration, capture more ultrafine particles, and maintain airflow better over time.

Understanding HEPA Filter Ratings

Beyond the HEPA classification, filters are also rated on additional performance criteria using testing standards from organizations like AHAM, ASHRAE and IEST:

• MERV – Minimum Efficiency Reporting Value (ASHRAE 52.2) – measures filter effectiveness from 1 to 16+. HEPA filters are MERV 17 to 20.
• MPR – Microparticle Performance Rating (AHAM AC-1) – measures ability to capture 0.1 to 1 micron particles like some bacteria and smoke particles. HEPA filters typically have 2000+ MPR.
• Dust Spot Efficiency – measures ability to capture 3-10 micron particles like mold, dust and pollen spores. HEPA filters achieve 85%+.
• Initial Resistance – measures air pressure drop across filter in clean condition. Lower is better for airflow. under 1.0 inches w.g. is ideal.
• CADR Ratings – Clean Air Delivery Rate (AHAM AC-1) measures volume of filtered air delivered for dust, pollen and smoke. Higher numbers are better.

These ratings provide assurance of filtration performance for smoke, allergens, and other pollutants. High-quality HEPA filters will excel across all criteria.

HEPA Filter FAQs

How long do HEPA filters last?

Most HEPA filters are effective for 6-12 months under normal use before needing replacement. Heavy smoke, dust or pet dander can clog filters more quickly.

What are HEPA filters made of?

HEPA filters contain a dense web of tiny glass fibers or an alternative synthetic material engineered to capture extremely small particles.

Can you clean and reuse a HEPA filter?

Unfortunately HEPA filters cannot be effectively cleaned, washed or renewed once they become clogged. The tight mesh becomes damaged, reducing filtration performance.

What allergens do HEPA filters remove?

In addition to smoke, HEPA filters capture pollen, mold spores, pet dander, dust mites, bacteria and other microscopic allergens and irritants.

Why Does My Air Purifier Smell Like Burning?

If your air purifier suddenly starts emitting a burning or chemical smell, don’t panic. There are a few potential causes and solutions.

1. Dirty or Clogged Filter

The most common reason an air purifier smells like burning is a buildup of dust, hair, and other debris on the filter. Much like a clogged air vent, a dirty filter can cause the motor to overheat and give off an unpleasant burning odor.

The fix is simple – clean or replace your filter. Refer to your owner’s manual for specifics on your model. You may need to vacuum the filter, soak it in warm water, or replace it entirely. Replacing filters every 3-6 months is recommended for optimal performance.

2. Electrical Issue

If cleaning the filter doesn’t solve the burning smell, it could point to an internal electrical issue. Air purifiers contain motors, fans, and control boards that can overheat or short circuit. Pressing a reset button or unplugging the unit for a few hours may help, but a persistent burning smell likely means professional repair or replacement is needed.

3. Singed Dust

Some air purifiers use an electrostatic filter that actually attracts dust and particles to metal plates inside the unit. Over time, this collected debris can get singed by the electrical charge and create a burning odor. Cleaning the metal filter plates or replacing the electrostatic filter should take care of the issue.

4. Ozone Production

Certain air purifiers designed to generate ozone may emit a metallic, chlorine-like odor. While ozone can help sanitize the air, high levels can cause respiratory irritation in humans. Make sure your ozone setting isn’t too high if this is the cause of the burning smell.

When to Be Concerned

A minor burning smell that goes away quickly after cleaning the filter is no cause for alarm. However, if the odor persists after troubleshooting, unplug the unit and contact the manufacturer – prolonged overheating can lead to fire hazard.

Also be wary if the burning smell is accompanied by other symptoms like loud noises, sparks, flickering lights, or electrical shocks. Unplug the air purifier immediately and have it inspected by a professional.

FAQ

Why does my air purifier smell like chemicals?

Chemical smells from an air purifier are often caused by ozone production. Make sure the ozone setting isn’t too high if this is the case. A dirty filter or electrical issue can also cause strange chemical odors in some cases.

Is it normal for air purifiers to smell at first?

It’s common for new air purifiers to have a “new electronics” smell at first as the motor breaks in. This should fade over the first few days. Persistent or strong chemical/burning odors are not normal.

Can air purifiers catch fire?

Air purifiers are generally designed to prevent fire hazards, but malfunctions do rarely occur. Prolonged overheating, electrical shorts, and motor issues can lead to fire if not addressed promptly.

Why does my air purifier smell like poop?

Unusual smells like rotten eggs or poop are not common with air purifiers. The culprit is likely an external source, not the unit itself. Try locating and removing the odor source elsewhere in the room.

• Actively circulates and filters air – doesn’t rely on central HVAC system
• Can cover areas up to 1000 square feet or more
• Uses HEPA filters that capture 99.97% of particles 0.3 microns or larger
• Added features like UV light to kill germs and mold
• Can help reduce allergies, asthma, and symptoms from indoor pollutants

Air Filters

Air filters are filtration systems that attach to central heating and air conditioning (HVAC) units to help clean the air that circulates throughout a home. As air passes through the HVAC system, the filter traps many pollutants before releasing cleaner air through the home’s vents.

Benefits of using air filters include:

• Filters air throughout entire home via central HVAC system
• Less expensive upfront cost than buying air purifiers
• Various filter types available from basic to HEPA
• Easy to replace filters when needed
• Can reduce dust, pet dander, mold spores, and allergens in the air

Key Differences

Air Purifiers	Air Filters
Standalone units that filter individual rooms	Attach to central HVAC system to filter whole home
Continuously circulates and filters air	Filters air only as it passes through HVAC system
Typically have HEPA filters	Range of filter types from basic to HEPA
More expensive initial purchase	Lower upfront cost for filters
Require more frequent filter changes	Only need annual or semi-annual filter changes

FAQ

1. Which is better for dust and allergies?

For reducing dust and allergy symptoms, air purifiers may work better since they actively filter the air continuously. High-quality HEPA purifiers can capture 99.97% of fine particles like dust, dander, and pollen that irritate allergies.

2. Do I need an air purifier if I already have HVAC filters?

It depends on your specific air quality concerns. If you have severe allergies or sensitivities, an air purifier in problem rooms may still help reduce symptoms. For general dust and pollen control, good HVAC filters may be sufficient.

3. How often should you change air filters?

HVAC filters should be changed every 3-6 months for optimal performance. Check your filter monthly and replace when it looks dirty. Air purifier filters need more frequent changes, often every few months.

4. Can air filters remove odors?

Basic HVAC filters are not very effective at removing odors or gaseous pollutants. Activated carbon filters, which are common in air purifiers, work better to adsorb odors and chemical fumes.

5. Do air filters use a lot of electricity?

Air filters use minimal electricity, only what’s needed to circulate air through the HVAC system. Air purifiers use more power since the fan must actively cycle air continuously through the filters.

6. What filter should I use for smoke?

For smoke removal, a high-efficiency HEPA filter is best. HEPA filters are able to capture the tiny particulate matter in cigarette, fireplace, and wildfire smoke.

7. Can air filters reduce VOCs?

Basic HVAC filters do not remove VOCs (volatile organic compounds) very well. Air purifiers with activated carbon filters are better at adsorbing VOCs from sources like paint fumes, cleaning chemicals, or office equipment.
