There are some important factors to consider when using an air purifier around pets:

  • Choose the right size air purifier – Make sure to pick an air purifier appropriately sized for the room based on the CADR (clean air delivery rate). Under-sized units will not clean the air effectively.
  • Select the proper filter types – The best air purifiers for pets have a HEPA filter to remove allergens and an activated carbon filter to reduce odors and chemicals.
  • Don’t use ionizing air purifiers – Ionizing air purifiers can produce trace amounts of ozone, which can be harmful to pets. Look for non-ionizing HEPA air purifiers instead.
  • Keep pets away during cleaning – Follow manufacturer’s instructions and keep pets out of the room when cleaning the filters to avoid direct exposure to accumulated allergens and pollutants.
  • Follow maintenance guidelines – Replace filters based on the manufacturer’s recommendations to keep the air purifier working properly. Monitor for any reduced airflow or odd smells that could indicate a filter needs replacement.
  • Consider the noise level – Make sure to choose an air purifier with a noise level that won’t disturb or stress pets. Some air purifiers are designed to be ultra quiet for pet owners.
  • Don’t obstruct air flow – Position the air purifier so furnishings, curtains, or other objects do not block the air intake or outlet, reducing its effectiveness.
