The purpose of fogging and spraying is to improve living conditions temporarily — lasting several weeks, or maybe a couple of months at a time.
Spraying and fogging are not complete solutions for all mold growth.
No product will truly eradicate all existing mold growth. However, continual cleaning and applications of the proper products can somewhat improve living conditions in a compromised environment. Of course, regular cleaning and maintenance can also help prevent mold from beginning in the first place.
Companies who claim that their products can eradicate mold issues entirely should not be trusted.
Prior to remediation (or leaving a home), regular cleaning and fogging can make a bad situation somewhat more tolerable and possibly safer.
These products can be applied via foggers and sprayers to combat mold growth on surfaces.
These products can be applied using sprayer bottles, cloths, or foggers and allowed to dry on surfaces or wiped clean.
Concrobium is best for severely moldy situations, in hard-to-clean crawl spaces, attics, HVAC systems, & moldier homes. This is due to more aggressive anti-mold action and the fact that Concrobium is designed to remain on surfaces long-term, killing and sealing mold underneath a layer of hardened product.
How It Works:
Concrobium actually encapsulates and suffocates (& crushes) mold, killing it.
The product is designed to invisibly remain on surfaces indefinitely, acting as a mold deterrent.
Apply via sprayer, cloth, or fogger and leave on surface indefinitely.
Concrobium highly recommends reapplying another coat if you wipe up residue, to prevent more mold growth.
NOT an all-purpose cleaner and disinfectant.
Benefect Decon 30
Benefect Decon 30 is best for non-porous, hard surfaces where mold growth can be properly removed — as well as prevention.
How It Works:
100% natural, essential oil-based thymol is the active ingredient. It is a potent disinfectant.
How To Apply:
Apply via sprayer, cloth, or fogger and leave on surface for at least 30 seconds before wiping up.
- Benefect claims there is no need to remove the product by wiping it — even on food-prep surfaces. The product will dissipate.
For all-purpose cleaning and disinfecting.
Vital Oxide is best for non-porous, hard surfaces where mold growth can be properly removed — as well as prevention.
HOW IT WORKS:
Powerful ammonium compounds oxidize and disinfect surfaces, safely.
Vital Oxide claims there is no need to wipe up — even on food-prep surfaces. The product will dissipate over a few weeks.
HOW TO APPLY:
Apply via sprayer, cloth, or fogger and leave on surface -or- wipe up after several minutes.
For all-purpose cleaning and disinfecting.
Any room or building that causes an immune reaction.
HOW IT WORKS:
This product uses citrus seed extracts.
EC3 doesn’t really make specific claims about disinfection.
EC3 is marketed specifically for mold — whereas Benefect and Vital Oxide are all-purpose cleaners and disinfectant.
HOW TO APPLY:
EC3 Mold Solution needs to be diluted with water and then “misted” by a spray bottle or fogger.
It makes 1 gallon of product — similar to the others on this list.
EC3 recommends using HEPA vacuum after application to remove spores.
NOT an all-purpose cleaner and disinfectant. Company claims: “EC3 is used to manage mold counts indoors” — but no claims of disinfection are made.
My favorite: Benefect Decon 30.
Cordless Electrostatic Sprayers
Electrostatic spraying is a remarkable technology that uses electricity to deliver a perfectly-even coating while using very little product.
These electrostatic sprayers achieve perfectly-even coverage, while using much less product, and now offer easy, cordless operation.
These sprayers seem to be made by one manufacturer and sold by various companies under their different brand names.
The technology is fabulous: Electrostatic spraying allows you to entirely coat a surface — perfectly and evenly — while using minimum product (whether disinfectant cleaner or paint or something else).
People who use these sprayers rave about how well they disinfect rooms, as well as the fantastic usability.
Quality Of Product
Unfortunately, there’s one downside: there are reports that these units are breaking too frequently. The manufacturers’ warranty is for 1-year, and I worry that this isn’t long enough for the price tag.
At this time, I hesitate to recommend this product — even though I really want to.
In the meantime, I’m hoping more similar products will enter the market.
Foggers work almost as well as electrostatic sprayers — but they’ll use more chemical/product.
They are usually placed in a room for a session, rather than used as a handheld.
Many foggers seem to be made by one manufacturer and sold by various companies under different labels.
This has great reviews — but looks very similar to the “TriJet”, which is cheaper.
This has all the same qualities as the rest of the foggers.
I’ve seen some reports of questionable construction on these.
B&G Ultra Lite 2400 Fogger
This might be the most rugged, well-built option.
The upgraded model (2600) has a hose for more portable spraying:
B&G Flex-A-Lite 2600
“TriJet” ULV Fogger
Great reviews, usually cheaper than the Concrobium, despite most likely being the exact same product.
All of these can be carried by hand and applied to specific areas — but you’ll probably need an extension cord.
The BioBalance Fogger
There’s another fogger out there: The BioBalance Fogger. This product may be well-made. However, I have a few reservations about the product for these reasons:
- BUNDLED — You cannot purchase the product on the website without also buying their $100 cleaning product.
- OVERHYPE — The BioBalance website speaks as though fogging is a total, complete solution for mold growth.
- OVERHYPE — They claim their product will kill mold inside walls from a single treatment.
All of these claims lead me to not trust the company. Therefore even though it’s possible their products might be great, these observations do not invoke trust. I’d love to be proven wrong. Perhaps they can address these issues at some point.
Ozone is a potent oxidizer, second only to fluorine gas in nature. It breaks down chemicals on contact and is powerfully antimicrobial against all manner of microbial life on surfaces and in the air.
Ozone breaks down mold’s mycotoxins and noxious VOC’s, as well as retards its growth. Ozone will kill bugs and break down the toxic chemicals in industrial and home products.
Understand Ozone Output
Ozone generators usually describe their output in terms of milligrams per hour.
A more powerful ozone generator will create 7000-10,000mg of ozone in one hour.
7000-10,000mg is appropriate for:
- Larger living spaces.
Smaller units will create 3000mg per hour.
3000-5,000mg is appropriate for:
- Single rooms
Like the other products listed above, ozone machines seem to be often made by the same manufacturer and marketed as different brands.
Unfortunately, ozone machines tend to come and go online. It’s also possible the current American trade war is temporarily affecting the availability of products, too. Hopefully, this improves and we can start recommending products again.
Fortunately, I’ve had good results with about 5 different ozone machines on Amazon.
I recommend you spend in the $80-100 (US) price range for a generator. You don’t get much benefit paying for more expensive products — the more expensive items aren’t any more durable. Based on my experience with these products, it will likely last you for 18 months to 2 years. After that, the ozone plates can be replaced for roughly $20. It may be a hassle to disassemble the machine and replace the plates.
How Frequently Should I Ozone?
In a very moldy situation, all spaces should be ozoned weekly. Move the generator from room to room, close the doors, and treat the space for 30 minutes to 2 hours, depending on the size of the room. Treat moldy spaces more aggressively, for longer durations each session.
For prevention, ozone each space once per month. In prevention, shorter durations for each session are adequate.
Be Sure To Ventilate Afterward
“Air out” the space after ozone treatment.
This is critical to remove the chemicals that have been broken down by ozone. Sometimes harmful chemicals break down to even more harmful chemicals. They must not become trapped in the space.
If the smell of the ozone is bothersome, the only real answer is to aggressively air out the space for many hours at a time.
Put box fans in windows and create a cross-flow to turn over the indoor air. For especially sensitive people, it can take days for a room to become tolerable again.
Sometimes, the materials in a room can determine how strong the ozone smell lingers. Oftentimes, porous items that are heavily contaminated with mold fumes will absorb the ozone smell the most.
What About This Style?
You may have seen many products that look like this.
The upside? They can release small amounts of ozone continually, which can retard mold growth.
However, they are usually quite limited in their air purification capabilities.
A better purchase will be a quality air purifier or wall-outlet mini-ozone generator.
