Review on EnviroKlenz Home Office Air Purifier by Ryan Foxz

We purchased three of these units for our business about two years ago Hometown. Initially, they worked flawlessly – quietly and efficiently. Then, one by one, the engines began to hum loudly. We replaced the first failed motor under warranty - we sent a noise recording and Enviroklenz sent us a brand new unit. But then the REPLACEMENT failed too. Now, after two years, despite recommended maintenance (change of filters etc.), they are all very noisy. We have contacted Timilon/Enviroklenz but I have no hope. These products are simply defective.
