How to Clean Your Car of Mold After Living in a Moldy House

Why is it important to clear your cars of mold? Cars are a source of contamination that you need to address in order to fully heal from CIRS.

Thankfully, we were able to clear our cars after recently living in a moldy home, which contaminated both our cars with mold. There were times I wasn’t sure we could clean them enough, but it was successful. We did not have to sell either car. It was a lot of work and shear endurance, but it worked!

How did we do it?

1) We purchased an ozone machine to 1st ozone the cars. We closed up the car and let the ozone machine run for 2 hours. Then, we let the car sit, closed up, for about 1 day. Car and ventilation system was turned off while ozoning the car.

2) We removed filters from the car’s ventilation system. You can do this before or after ozoning it. From what I understand, ozone passes through the filters and permeates everything.

3) Next, we fogged with EC3 by Micro Balance the entire car and ventilation system. We fogged at the inlet of the car vent system on the exterior, often found near front windshield; the car ventilation system was turned on, set on exterior air mode. Then, we set the air control on recirculation mode and fogged the interior of the car. We fogged the ventilation system and the inside of our car several times. Then, we turned our car on high fan mode and high heat in order to circulate and dry out the car.

4) Then, we replaced the car ventilation filters with a dual hepa and carbon filter. I believe they are made for most car models.

Tips: Fogging with EC3 or ozone treatment alone did not clean our cars fully. The reason, ozone destroys the mold spores but leaves the mycotoxins. EC3 destroys the mycotoxins as well as mold spores. EC3 alone did not permeate the car enough to clean out the ventilation system without the ozone treatment. A friend of mine pre the existence of EC3 had to sell both cars because ozone alone would not clear her cars of mold. Thankfully, there is EC3 now. When we ozoned our car and then fogged it with EC3, our car became happy for us.

  1. our vehicle is a 2007 and has NO rechangeable filters. do you know if this procedure would work just as well in that case? I recently ran a UV/ozone for 1 & 1/2 hours and it helped a lot, despite the fact that I could not run the AC system during the treatment. I was not expecting it to do as much as it did to the AC system. Thank you for this article!

    1. Hi, Glad the article was helpful! Whether a car has air filters or not shouldn’t matter for ozone treatment. From what I understand, ozone passes through the filters and permeates everything in the ventilation system and car. Our car and ventilation system was turned off while ozoning the car. Have a blessed day!
