Using Ozone to Clean up Toxins

Effectiveness of Ozone Generators

Ozone kills mould on surfaces, eliminates many VOCS and odours such as perfume. It can also remediate smoke smell in certain materials. It is most effective at high levels which people refer to as “shock treatments”.

I’m using the PT101-2K Ozone Generator (covers 3500 sq. ft. for odours, 400 sq ft for mould) which I recommend.

My Camplite trailer became contaminated when the countertop went mouldy. I washed down the walls and aired it out, but porous materials including the bedding and flooring were still a big concern of mine.

The floor and plastics also still gave off a chemical smell.

Other sensitive people were reacting to the chemical smell.

My Results

– Chemical smell in trailer reduced after a few treatments

– Can go into trailer without any reaction now but there was also lots of airing out for months

– Smell removed from funky smelling fabric (towel that had a smell that washing would not remove)

– Removed fragrance from clothing, but not dry cleaning chemical smell

Results From my Network on Healclick and Facebook:

One Healclick user found it really useful in the car. She says: “I was reacting very badly to the car and it smelled like perfumed cleaning chemicals. I just couldn’t be in the car unless I really had to. Now the smell is gone.” I have heard the same experience on Facebook as well – ozone helping a lot with fragrance in a car. Two other Healclick users found it useful to shock a room or tent, and to “flash” belongings before any toxins could take hold. These two Healclick users I know well and they are extremely reactive to mould.

I think this is very useful if fragrance and smoke smell are your big concerns. It is very good to clean up some VOCs as well. I wish I had this when I first bought the Camplite to get rid of the new chemical smell and could have made it usable a lot sooner. I will also continue to use this on funky smelling clothing, to flash the trailer after people use it, and on friends cars and trailers as needed. I will update the post as I continue to use it.

You have to be sure you are using it safely and understand the limitations –


– Ozone is a toxic gas. People and pets should not be in the building when an ozone machine is on

– Ozone cannot remove carbon monoxide or formaldehyde (EPA)

– Ozone needs to be 5-10 x above safe levels for humans to impact bacteria and mould (Shoemaker)

– The place should be aired out after using ozone to make sure that the gas is not inhaled. Ozone is unstable and will quickly dissipate. If other VOCs form (see below) then it is necessary to air out the place for a while.

– One reason government health sites do not recommend the machines is that the shock treatment used to get rid of toxins is a very harmful level if inhaled. Even the low levels recommended by some manufacturers is probably harmful to anyone sensitive to toxins. So there is a risk if someone does not know how to use it safely. It is possible they are also wary because of the negative reaction outlined below. In many conventional houses it might not be possible to avoid all those reactions.


– It cannot get into pourous materials to remove mould or chemicals (EPA)

– It will not help with chlorinated hydrocarbons (vinyl, plastics etc.) (EHC)

– Kills mould spores but does not denature the toxins (EHC). Once the mould is killed it should be HEPA vacuumed up.

– May not work on clothes and shoes (Shoemaker)

Negative Reactions

Ozone reacts negatively with some compounds creating more VOCS. Some of the substances it reacts to are:

– New carpets (EPA)

– Active tobacco smoke (EPA)

– Terpenes (to form formaldehyde) (CDH)

– Styrene (EHC)

– Floor finish that contains pinine (Shoemaker)

Side Effects

High doses of ozone used to really clear out toxins will also degrade or harm certain materials such as:

– Plants

– Rubber

– Coating of electrical wires

– Fabric

– Some Artwork
