Air Purifiers

Just to clarify a prior question, I had; I’ve heard that ionized air can be potentially harmful (i.e. free radicals) so I want to avoid air cleaners that ionize air. The 3M Filtrete electrostatic polyolefin-based filters (very common in furnace filters, and now as part of a standalone air purifier) are pre-charged with a static charge to attract dirt, dust, and particles of inflowing air.

My question is, as non-ionized (regular) air travels through the filter (via a simple fan, there is no ionizer involved) is there any way that it could pick up any of the charge on the electrostatic filter, or that the air can become somewhat ionized in any way or form after it leaves the filter? Now, AFAIK, air doesn’t conduct charges well, so my guess would be no, but I’d like to have an expert opinion.

I live in an older house (about 1100 sq. ft.). We have a terrible mold problem. I’ve been using a HEPA system, but the filters are .00 each, and it takes three of them. I’m interested in hearing from anyone who has experience with the Ionic Pro Turbo air purifier, as to how well it performs, or what is the best, affordable, air purification system.
In the meanwhile, I think I found a better solution. I bought two 20 inch, square, window fans (.85 each). Then, I bought two 20X20 3M Ultra Allergen Filterete furnace filters (.75 each), and simply put them on the back side of the fan.

Man, does it ever filter. It puts out a lot of air, and the filters catch allergenic particles such as mold, and even smoke. So far, it works great. And it sure beats paying 0, for an air purifier, (which is basically just a fan with an allergenic furnace type filter on it anyway), and .00 for replacement filters!

My furnace and central air share the same ducts. How often should I change the filter? (I use the 3M Filtrete brand).

The home inspector said once every 3 months, the guy who installed the central air said once a month.

Filtrete cabin air filters help capture dust, pollen and other particles from the air passing through the filter into your car’s interior and are designed to help eliminate particles measuring 5 microns or more in diameter and 50% of smaller particles from the air entering the passenger compartment.
