I purchased these for my daughter and her family because they have allergies and one of the children has a respiratory problem. She said the first night she used her allergies were much better...so I think it's been a great purchase

I bought this about 2 weeks ago and my whole family can feel the difference in the air quality. The only time allergies act up is when we have been outside or I've turned the filters off overnight. So now I'm leaving then on, but lowered the fan speed. Very pleased and surprised at how well they work.

These are even better than I expected! I do not need room freshener anymore. Just after a few hours of one being plugged in and running, my teenage son’s room FINALLY lost its funk smell that I have been trying to get rid of since Jr high! I have ordered 2 more so I will never have to sneeze over room fresheners again!!

With kids recently moving back home and being allergic to cats, this helped in freeing the air of the cat allergens and kitty litter dust. On top of that being allergy season , it helped withthat as well. Now i cam have my grandkids over and have a one up on allergens and stuffy noses . It was a great buy! One in living room and one In kids bedroom. Sounds just like a fan on, so not to noisy i think

Since I purchased these I have not had to take a decongestant at bedtime like I have for decades.

Prompt delivery & product cleans the air very well, and is easy to use.

One worked, other was very noisy. Having problems returning.

Compared to other models, they are loud and on a lower fan setting they’re louder.

I wish it had a remote! But I really like them

Purchased online, easy order and delivery process. Great product for the cost.
