This purifier (PR20) is great, I have had the older one (BZ2000) for about 15 years, and it died. Bought one first of the year 2020, was using it and let my granddaughter use it for a month, so I bought another one. They are great, nice go come into the house and it smells fresh and clean. It is a little prices, but it does the work that biozone claims.
Couldn't resist ordering the PR20 at the same time. It's still awesome, how something so small and maintenance-free can work so well. My asthma hates it; I love it. Thanks for such a great product. I want one for my car.
Dear Airfree, As a longstanding sufferer from dust mites, hay fever and many other things, I think Airfree is fantastic. In the past, I had to close up the house and lie in a dark room for hours to feel better.
After much research and many mistake purchases of lesser units, Biozone 2000 (PR20) is my first choice for an air filter/ cleaner for my home-office. I have one on each floor running full time and love them.
