I am not an X-Spurt, this story is a personal experience and the info is what I found readily available on the net.


About 4yrs ago a friend with a pre & post daycare school for kid business had a major water incursion over a holiday weekend. The leak caused major mold infestation and she was in a tizzy of how to get rid of the mold and get back in business.

The mold abatement company had air dryers and mold cleaning services, but she couldn't afford to tear the walls down and still be inspected by the county's health department as "kid-safe".

side note: She had just completed 4 months retrofitting the building for her business and had only been open for less than a month. Her last building had dropped her lease.

She asked me about ionizers. They would do the trick but were they a hazard?

There is a problem. Ionizers create ozone and there are EPA standards for ozone exposure.

In the above story, the mold abatement company was able to use a combination of filters, dryers, and ionizers while the building was empty and forced air flush the building in the morning. Not the fastest but it enabled the business to get back in operation, fairly quick.

Do your own homework..

I have an apt house with two apt's which have central HVAC systems. I use either the #11 or #13 filters from here. If I had a central HVAC for my place, I'd use a #13
I have window units though.

My understanding of UV light is that it won't treat the air cause it's moving past too fast, but you have it shine on the filter. It will kill the virus if it's on something like dust particle stuck on a filter. I'd assume that a free floating virus would still pass through. Better then nothing I suppose.

Below is a link to something that appears to be new technology. Can not speak as to it being any good or not. It's supposed to treat the air as it passes in spite of the air flow.
