How We Tested

We researched and tested over 15 air purifiers in both allergy-prone homes and sealed testing spaces. Each unit was evaluated for its ability to capture airborne particles like pollen, pet dander, mold spores, and dust.

We measured CADR ratings (Clean Air Delivery Rate), HEPA filter effectiveness, noise levels, energy use, and ease of maintenance. Units were tested in rooms of various sizes, with feedback collected from allergy sufferers over a four-week period.

Bonus points were given to purifiers with smart sensors, automatic fan speed adjustments, and app connectivity.
