I wrote to you guys previously. I had mold in my HVAC system and had the coils, pan, drain and plenum cleaned twice but it still had a mold smell. Finally I fogged the HVAC system twice with Concrobium Mold Control until there was a thick visible fog throughout the house, and this got rid of the mold smell. But now I need to make sure that the smell doesn’t come back or maybe filter the air from the HVAC system so that at least the mold will be filtered before it’s distributed to my rooms. This is speculation on my part. Are there any reasonable ways to control or filter any mold in my system? I have heard some reports that filtering does more harm than good and can actually make mold grow or the filters can harbor mold??
I can’t fog that often because I had to leave my house for several days because the fogging agent hurt my lungs. And I can’t use any HVAC purifier that releases ionized oxidizers (ActiveTek or RGF) into the air because this makes me sick, as does the ozone from UV lights. The humidity in my home has been consistently between 32 to 41 percent, and I live in Roseville, CA. I plan to have the coils, pan and drain cleaned every 6 months and to change the air intake filters with a Merv 8 filter every two to three months. I’m hoping that the leftover mold smell was maybe spores in my ducting that the fogging got to. Two techs have looked in the attic and every place visible and there aren’t any signs of water damage. So do you guys have any ideas for how to keep the mold out of my system or how to filter it? I had to leave my house until I can get this resolved so I would really appreciate any ideas. Thank you so much.
