What are mold bombs, ULV, and thermal fogging?
There are three types of mold foggers – one releases fog from an aerosol can (mold bomb fogger) and the other from a small machine – ULV cold foggers and thermal foggers. They all do the same thing, which is release atomized particles into the air that kills bacteria, viruses, mold, and spores from surface areas and the air, while some even deodorize to get rid of any unpleasant mold and mildew smells.
How do they work?
They contain a mold fogging solution in liquid form. It releases it as a fog (atomized particles measured microns in size) into the air.
The particles spread throughout the room and cover all surface areas and walls. Also, when in in the air they attach themselves to mold spores, mycotoxins, bacteria, and other allergy causing particles, kills them and then weighs them down to the ground and onto surface areas. These particles can reach even the most hard-to-reach places and kills all mold upon contact.
Also, the smaller the atomized particles in the fog are, the more effective it will be.
In this article we won’t be covering thermal fogging, because it’s not as DIY friendly as the ULV and aerosol can methods – mainly because it uses a lot of heat to create atomized particles and it can therefore be a fire hazard.
Why use a mold fogger?
It kills mold spores: Once mold starts growing in your home, it will begin spreading quickly by releasing spores into the air that colonizes other areas. The chemicals that a mold bomb fogger releases kill these spores, which stops further colonization.
It kills mold in hard-to-reach places: Mold hates the light and thus usually thrives in dark areas that are out of sight and hard to reach. Crawl spaces, the inside of air conditioners, and attics are just a few examples of such places.
It’s an excellent preventative measure: You don’t always have to wait for mold to appear before taking action, because setting off a mold bomb fogger in high-risk parts of your home on occasion is a great preventative measure.
It sanitizes and disinfects: The chemicals contained in these products kill so much more than just mold and mildew. It kills up to 99% of all bacteria and viruses such as covid-19, herpes, H1N1 influenza, HIV, and so much more.
How to use a mold bomb fogger safely and correctly
1: First, check the can to see how many square meters the mold bomb can fog. If the room has more square meters than the fogger can handle, then you may want to consider using two cans.
2: Place the can in the center of the room and clear any obstructions. Close all windows and remove or cover/remove any sensitive items (paper). Also, no humans or pets are to be in the room during fogging – even if the fogging solution is non-toxic.
3: Set the fogger off as per instructions on the can. It will give you a couple of seconds to leave the room before the fog gets released. Leave the room and close the door for 2 hours while it sanitizes and disinfects.
4: Once sufficient time has passed, enter the room, open the windows and discard the can.
How to use a ULV (Ultra Low Volume) fogger safely and correctly
1: Place the ULV fogger in the center of the room, close the windows, and clear any obstructions that may be in the way. Close all windows and remove or cover/remove any sensitive items (paper).
2: Add your mold fogging solution into the tank and set your desired settings (density of the fog and timer). Set the nozzle to release the fog at a 60-degree angle and set the density of the fog on the finest possible setting.
3: Make sure no one is in the room (pets included), and start the machine. Leave the room and close the door.
4: Switch the machine off once the fogger has finished and wait approximately 30 minutes for the fog to dissipate before opening the windows.
The best mold bomb foggers
The two best mold bomb foggers are Fog U and Biocide – both are non-toxic, highly effective against mold and their spores, and safe to use around humans and pets.
Please note: Atomized particles released by mold bomb foggers float in the air for long periods of time and are easily absorbed through the lungs. It’s best not to be in the room while fogging, even if the solution used is natural and non-toxic. Open the windows and doors after fogging has been completed, and wait a little while for the fog to dissipate.
Fog U Mold Cleaner & Deodorizer
Fog U Mold Cleaner kills mold, mycotoxins, mildew, bacteria, and allergy-causing particles with natural enzymes while deodorizing.
It has a 360° nozzle that you can use as a total release fogger or spray can.
One can treats an area of up to 10′ x 10′ (800 cubic feet), provides months of protection, and is perfectly safe for use around people and pets.
To use Fog U as a mold bomb fogger, place the can in the center of the room, inside crawl space, ductwork, or wherever you need it and press down until you hear a click. Once it starts fogging, leave the room and close the door. Stay out for 2 hours.
There is no need to wash or wipe any surface areas down because the product is 100% biodegradable and non-toxic.
Biocide Mold Bomb Fogger
The alcohol-based Biocide mold bomb fogger is easy-to-use and trusted by hospitals, daycare centers, and schools.
It kills up to 99.99% of all mildew, mold, bacteria, and viruses in one single application.
To use it, simply place the can in the center of the room, remove the cap and push down on the tab until you hear a click. The can will then start fogging.
Also, it’s recommended to stay clear of the room for 2 hours. The best part is that it’s not necessary to clean any of the surface areas afterward, and it deodorizes too.
The best ULV foggers
EC3 Sanitizer Fogger and Mold Solution Concentrate Bundle
The EC3 Sanitizer Fogger from MicroBalance sprays an ultra-thin mist that fills and covers indoor spaces.
It’s a high-quality ULV fogger that comes with a 1-year warranty that covers defects and mechanical issues, but the best part is that the fogger comes with a bottle of fogging solution, so you don’t have to buy one separately.
The included solution is also from MicroBalance and is made from 100% natural ingredients, is non-toxic, and has citrus seed extracts as its base ingredient.
SwanSoft ULV Fogger Machine
The SwanSoft ULV Fogger Machine is a high-quality ULV fogger that you can use for mold and pest control.
It’s designed to be carried around as you fog because of its durable high-density polypropylene body so it can handle being bumped around. Also, the buckle and shoulder pad makes it comfortable to carry around for extended periods.
The tank can hold 1.85 gallons of mold control or pesticide solution and a full tank covers around 4,000 sq. ft.
The ULV fogger weighs 9.68 pounds and has dimensions of 18.6 x 11.89 x 8.9 inches.
Curtis- Dyna Tornado Flex Fogger
The Curtis-Dyna Tornado Flex Fogger is the best ULV fogger on this list – and also the most expensive.
It fogs atomized particles as small as 5 microns in size which means it infiltrates even the smallest cracks and kills more mold spores and mycotoxins. It also features a large formulation filter and allows you to have precision control of the output spray because of its advanced metering valve.
The fogger is multi-purpose too because you can put pesticide solutions in it as well if you want to eradicate pests.
You can use it as a total release fogger or attach the 18″ hose and walk around with it as you fumigate.
It’s ideal for use in residential homes, warehouses, hotels, schools, and anywhere else you can imagine.

The product is made in the USA, weighs 8 pounds, and has dimensions of 11 x 16 x 8 inches.
How to choose the best mold fogging solution
If you decide to use a ULV fogger instead of a mold bomb, then you should choose which chemical to use. After all, a fogging device is only as effective as the mold fogging solution used with it.
There are many chemicals to choose from. Some are toxic, while others don’t kill mold, and instead merely encapsulate it to prevent it from spreading spores around.
Also, be very careful with what you use. For example, hydrogen peroxide is an excellent mold killer and is safe to use in liquid form. However, when turned into a mist, it can damage items and cause serious respiratory problems. So always be sure that the fogging solution you choose has been specifically formulated for use in a fogger.
But the best mold fogging solution is one that is natural, non-toxic, and that kills mold, including its spores. It’s safer for humans and pets and your home/possessions won’t get damaged or covered in a layer of poison.
The two best mold fogging solutions we could find are the EC3 Mold Solution Concentrate and Concrobium Mold Control.
Please note: Atomized particles produced by ULV foggers float in the air for long periods of time and are easily absorbed through the lungs. It’s best not to be in the room while fogging, even if the solution used is natural and non-toxic. Open the windows and doors after fogging has been completed, and wait a little while for the fog to dissipate.
EC3 Mold Solution Concentrate
The EC3 Mold Solution Concentrate from Micro Balance is the best mold fogger solution you will find.
Not only does it consist entirely of 100% natural ingredients (citrus seed extracts, vegetable glycerine, and distilled water), but it also kills mold, spores (mycotoxins), and bacteria while deodorizing. It’s safe for use on all materials.
The key ingredient is the citrus seed extracts. Independent lab studies have shown that when applied to mold and mycotoxins in small dosages, it changes the cell structure and cell membranes. In higher dosages, it causes loss of homeostasis, membrane damage, and cell death.
The product, which is made in the USA, comes in 16 oz. bottle and makes 1 gallon after being diluted. You can put the solution into a fogger, a spray bottle, or even wash moldy clothes with it.
Concrobium Mold Control
Concrobium is an odorless and safe mold control solution that can be used on all types of surfaces, materials, and fabrics.
It also works great as a mold fogger solution in ULV fogging devices.
The solution contains no harsh chemicals and its active ingredient is Sodium Carbonate – so it’s perfectly safe for use around pets and humans.
For best results, do not dilute with water or add any other solutions to the Concrobium solution when using it in a fogger.
