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

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!!

I purchased these due to having some severe allergy problems. I was skeptical but a few weeks after using them for 4-6 hours a day and all night there was a big improvement. We don't have pets and didn't get them to improve the smell of the house, but could tell the place smelled great after a couple hours use.

I had some Honeywell's that had run their course so when we moved into a new home, I wanted new hepa-type air cleaners. We bought the two-pack online and arrived quickly w/o incident. Within a few days, one started to sound like a train. I ordered them again w/o incident and returned the defective on and the un-opened one. Again, within a few days the new one began to get louder and louder. What's worse is, the original one that we kept, started smelling like faulty wiring. I gave the stars to Sams for excellent customer service in shipping and returning.

We really like this air purifier and use it all day. Having the blue light to help clean germs is a plus. I like that replacement filters can be bought at Walmart. It is not loud for us and I like that the fan can be adjusted and the blue light can be turned on and off.

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

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.

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.
