Does anyone else use an air purifier?

The Atmosphere Air Purifier Recently Passed Rigorous Scientific Testing to Become the First Asthma & Allergy Friendly Certified Air Purifier.

This certification process is very thorough and difficult, but scientists have developed the Atmosphere Air Purifier to meet the strictest guidelines for air purity.

I use this for my allergies. Its a great product.

The price has DROPPED by a huge amount on this Air Purifier since I bought it.
That means its now affordable enough to also have my main floor cleared of pollen, bacteria, dust mites, viruses, smoke, and other airborne impurities too. Amazing! It removes up to 99.99% of airborne pollutant particles that pass through the system.
Passing the certification standard also means this air cleaner does not contribute to ozone levels in your home.
One has made a huge difference upstairs and the price reduction means downstairs will now be covered too.
