The product has proved very effective in my home. It is used in the master bedroom and is efficient at removing ugly things from the air, even when used on the lower setting.
I have been using the Blueair purifier for over ten years. There was time when I stopped using it for a few months and I could feel the difference in the air quality in my living room. I spend most of the day in my living room and the air quality is highly important to me. It is important to replace the filters at the recommended time.
Pollen is almost a year round problem here in the NW woods where I live. A Blueair 600 were the first purifier I purchased, over a decade ago, and it is still running. Since then, I've purchased another. I change the filters every six months, and there's no substitute for the branded filters. Allergy Buyers Group is a great place to buy them, especially during the Labor Day Sale.
My review says it all.
Everything nice but the price!
