What to Look for in Air Purifiers for Allergies

To choose the best air purifier that can improve indoor air quality and help reduce allergy symptoms, here are a few key factors to consider: (2)

1. True High-Efficiency Particulate Air Filters (HEPA): Choose a HEPA filter that can capture 99.97% of particles as small as 0.3 microns to help eliminate allergens like pollen, dust, mold, and pet dander.

2. Clean Air Delivery rate (CADR): CADR measures how quickly a purifier can remove allergens from the air in a specific room size. Air purifiers with higher CADR ratings often offer more efficient air cleaning.

3. Room size: Make sure the CADR matches the room size where you plan to use it for effective air purification. 

4. Multistage filtration system: Choose air purifiers with at least three filtration stages to capture a broader range of air pollutants and allergens. 

5. Particulate matter  2.5 (PM2.5): PM2.5s are fine particles that are small enough to enter the respiratory system and worsen allergy symptoms. Choose filters that capture particles with a diameter of 2.5 microns (PM2.5)  or less. 

6. Costs: Some air purifiers are more expensive than others. However, aside from the upfront costs of air purifiers, you have to consider the costs of replacement filters. If you are on a budget, choose purifiers that take longer to replace.

While air purifiers may help reduce allergens in your home and improve indoor air quality, they do not change how your immune system responds to these allergens. As a result, exposure to allergens outside the home, or to any new allergen introduced indoors, may still trigger allergy symptoms.

To reduce your overall allergy burden, it is best to treat allergies at the root while also keeping your environment as allergen-free as possible.
