Did a lot of research, settled on this air purifier. Noticed a HUGE difference on the FIRST day. I've had mine for about a year, and really really like them. I had never owned an air purifier before and thought it might even be a scam to "clean" the air. I was wrong. Once I pulled out the filter and see the gray air it sucked in, I was hooked. I bought more than 1, because we have a ton of allergy sufferers in our house. Highly recommended.
I've tried several different brands of air filters and have found the Winix to be top-notch. Sturdy, dependable, and as long as you change out the filters as they recommend, it does an excellent job at filtering odors and particulates. I have several in my offices and in my home.
I have COPD and this keeps the air clean and fresh. I would highly recommend this for anyone with breathing problems. Quiet and efficient only drawback is the price of the filters.
My air-conditioner is working so much more efficiently now that I have the air filter
