Best Air Purifier For Allergies And Asthma

Indoor spaces can have significantly increased concentrations of allergens and pollutants that can cause allergies and aggravate symptoms of asthma. Air purifiers are simple, portable devices that can filter the air you breathe, removing microscopic allergen and dissolved toxic gases. 

Can air purifiers help reduce allergic reactions?

Air purifiers help remove some allergens that can trigger allergic reactions. Although there are no official recommendations for their use to prevent allergies, many medical experts and research studies have come out validating them as an effective tool.

Studies have shown that using air purifiers with appropriate HEPA or PECO filters helps reduce the concentration of particulate matter and house dust mites that are common allergens, and can be used as a therapeutic option.

Here are a few important things to keep in mind when selecting an air purifier:

What do you need to filter?

Select an air purifier with an air filter that suits your needs, depending on the size and nature of allergens that trigger your allergies. Different types of filters include:

  • HEPA filters – These remove small particles from the air.
  • UV air filters – These deactivate the microbes in the air.
  • Ion filters – These remove particles from the air using a high voltage to ionize the air. 
  • Activated Carbon: These are good for removing dissolved fumes.
  • PECO filters – These remove even the smallest particles in the air.

What is the size of the area you need to filter?

The CADR (clean air delivery rate) determines how many square feet an air purifier can reach. Make sure the CADR matches the size of the space you are planning to get the air purifier for.
