Biozone Standard 500 Air Purifier

This company, "Biozone" is going out of business. The company can't keep up with the orders and returns area almost impossible. My unit did not work as described which i fond out after almost two months to get it. When I got the unit, it did not do what I expected it to. It took several more weeks of constant telephone battles to return the unit. Finally, I returned it. While I was dealing with Biozone I heard the company is going out of business. The owner of the company does on know how to run a business and cant keep up with the demand and quality control went down the tubes. I found out that there is another unit out there that is better and less expensive. I bought it and and I love it. I received it quickly and it cleaned my home beautifully. The unit, vision air purifier, is made by RGF a proven commercial company, sold by pure home air. Good luck
