Alen A350W

The Alen A350 and A375UV air purifiers offer complete air filtration removing allergens like dust and pet dander as well as common household odors and gases. During our testing both models removed over 90% of the particles in the air on the first...

Not our quietest air purifiers: The noise level on the Alen A350 and A357UV air purifiers is not unreasonable but it also is not whisper quiet. The first two speeds are relatively quiet and speed 3's quietness is subjective depending on your noise...

I searched all over for a good air purifier and found that this model is the 2nd best purifier. Since I put this in my kid's room she stopped coughing. The unit is bit noisy if you put the level to two but you'll get used to it after the first few...

Noticed an immediate improvement in air quality, could actually breathe out of my nose in the morning.
