Ken,

Costly tests can tell you but baring those, I think that is a good way to

see that particulate matter in air is low, so agreed. I think people here

are mostly concerned with mycotoxins that wouldn't show up that way.

However if air particle volume is down, that would mean source of mycotoxin

producing microbes are down and so should follow mycotoxin level would be

down or will be. It seems logical but don't know for certain. However

are not must mycotoxins so air clear of particulate matter

would be good sign of healthy air quality I would assume too.

Carl,

How often do you have to clean filters in a Hepa? I've heard problem with

them is that they collect particles so they are only as good as how much

they can hold before they aren't able to collect anymore. I would think new

one in home previously didn't have one would have to have new filter

replaced fairly soon in the beginning.

I think Ken is referring to not seeing individual particles but collective

particles being enough to create a hazy in air. I would think that could be

particles smaller than an individual could see. However I still have air

quality problems with home and I have no sunbeams in house, although I know

what he is referring to. I
