I'm purchasing a new house and have the option of having a Honeywell air cleaner cartridge installed on both of my Trane air handlers. Installation cost is $450/unit ($900 total). It contains a charged media filter that supposedly captures 98% of 10 micron size particles and 42% of 0.3 micron sized. Here is a web site for it: There is also an electronic version of this cleaner available, but the AC consultant said that wasn't worth the extra money over this one.

Recently, I saw the inside of my 11 year old AC and it was loaded with mold. And I had mold/fungus build up in my house in past years. I'm wondering if a built-in air cleaner would have helped. So now I'm trying to figure out if it's really worth forking over the $900. Do these air cleaners really work better than just the standard filter? Are they worth the money?

If you know anything about air cleaners such as this, please share your thoughts. I have seen many advertisements for portable air cleaners but I assume one that is built-in to the air handler, such as the Honeywell, would be more effective.

No, the filter will not make any noticeable difference in the mold problem. That is a problem with indoor air pollution caused by various products that 'out gas' and lack of adequate ventilation. Do a Google search for indoor air pollution and you will get lots of sites. The Mayo Clinic has one as well as EPA but they all say about the same things. Select your building products carefully and demand good ventilation. Consider a Heat Recovery Ventilator/Air to Air Exchanger (also other names). Don't skimp on bathroom and kitchen ventilation - be sure it vents to the outside or it does no good.
