Loved & Recommended by Doctors

For any living space, I would strongly recommend this filter. What I like about it is that its sensor monitors air quality and automatically keeps the fan low when the air is clean. If more particles show up, the fan speeds up, but never gets too loud.

Dr. Donald G. Nicholas (Internal medicine)

By cutting smoke, traffic pollution, and fine dust, this purifier can support healthier lungs and better long-term health, which is why I recommend the 240 HEPA Air Purifier for families big and small.

Dr. Anagha Agarwal (Internal medicine)

If cooking fumes, cigarette smoke, or pet odors linger in your home, I recommend having a PuroAir 240 on hand. Its activated carbon layer is made to take in gases and chemicals.

Dr. Luis Gutierrez, DO (Family medicine)

I recommend the PuroAir 240 to families because it helps tackle the common irritants that often build up at home, like dust, smoke, pet dander, and chemical fumes from cleaners or paints.

REPLACING YOUR FILTER

We recommend replacing your air purifier filter every 3 months or 90 days.  Due to build-up of captured air pollutants, waiting longer than 90 days could decrease the effectiveness of your air purifier.  During periods of poor air quality due to increased allergens, wildfire smoke, renovation projects, etc. we recommend replacing the filter sooner.
