How Often Is Cleaning of ESP Air Purifier Required?
RE: About Every Three Weeks Depending Upon Your Atmospheric Conditions.

Is The ESP Air Purifier with Ozonizer Considered As An Ozone Generator?
RE: No. Ozone Generators Produce Large Amounts of Ozone and It is Considered
These Unsafe For Household Use. The ESP Air Purifier with Ozonizer Electrosta-
tically Removes Particles From The Air and Release Only Trace Amounts of
Ozone.

 My ESP Air Purifier with Ozonizer was Making A “Cracking” Sound and
Now It Does Not Seem To Be Cleaning The Air Any More. Is It Broken?
RE: No. The ESP Air Purifier with Ozonizer Needs To Be Cleaned. When Too
Much Dirt Accumulates on The Collector and Electrostatic Wire, The Power
to The Collector Turns-Off, But The Fan Will Continue to Run. Clean The Unit
and It Should Then Operate Normally.
