  • Loving this and our clean air

    This is the best purchase we have made in a long time. We have this a short time and cannot believe the difference it has made for us and with our allergies. We live in an apartment complex where just about everyone smokes and our apartment reeks of the smell of smoke and other unwanted odors. We are costantly sneezing or sick from it. The first time we used this it cleared the air and smelled clean and fresh gor the first time. It is so quiet you don't even know it's on. It goes through our entire apartment. I highly recommend this product. You won't regret purchasing it.

  • Made my home a better place!

    I live in Arizona...and we have lots of fine dust. Last year I noticed whenever I was in a room where a ceiling fan was turning or a tower fan, I had a dry hacking chronic cough. It even woke me up during the night. My husband suggested I may have dust allergies...which I have never had! After purchasing this air purifier my coughing has stopped! I will buy a second one so there is one in the den and our bedroom. It also helps to put my bed pillows in the dryer for 10 minutes on high heat once a week to kill dust mites.

  • Love it.

    this works well I have 3 in my home. I have asthma. With 4 cats in the house the air at times is pullited with cat dander, dust from the litter box. ect. These air purifiers really do a great job in cleaning the air!

  • Clean air

    I was skeptic but I can say that this purifier is awesome! I know my bedroom air feels cleaner and my husband doesn't snore as much.... lol... it's always on when I am home and when I sleep that sleep mode is very quiet , I am a light sleeper and if it wasn't it would really bother me. I like that I can wash the filter and my only complaint would be that instead of programming it to turn off I would rather have it the other way around. But I willProbably purchase another for my living room because I have bad allergies and I think it is helping me!
