Say goodbye to pesky mold growth!

Mold is one thing that almost no one is a stranger to. This multicellular fungus relies heavily on moisture and somehow makes its way everywhere. It shows up in different places both indoors and outdoors as long as sufficient moisture is available.

As well as being a danger to your health and your home, mold is a terrible eyesore. It’s not uncommon that it defaces anything it grows on. It also stinks up the place with a musty smell that will have you wrinkling your nose in disgust.

Mold is certainly not something you want in your home. So we’ve taken it upon ourselves to find the best mold foggers on the market to help you get rid of it.

Why Should You Remove Mold?

Mold is one of the worst things to find growing in your home. It develops so fast that you might not even notice it until it becomes a problem you can no longer ignore.

Apart from its unpleasant appearance and smells, mold can also be hazardous to your health. Therefore, it’s vital to eliminate mold and mildew from your living space as soon as you notice it.

Health Hazard

Granted, not everyone is sensitive to mold. However, those with allergies will face many health challenges of varying degrees of seriousness.

Mold reproduces by releasing microscopic spores that float around in the air before finding a place to rest. These spores can trigger allergies and lead to things like eye irritation and throat irritation. In some cases, skin irritation may even result.

Those with preexisting health issues, such as chronic lung disease, can end up with more severe problems like lung infections. Mold spores can also trigger asthma attacks for asthmatic patients.

Children and pets are also much more sensitive to mold spores and can end up with respiratory problems when exposed to it (1).

Structural Damage

Like all living things, mold needs nutrients to grow. It gets these necessary nutrients by feeding on organic matter.

Organic material is present in almost everything, from wood to clothes to drywall. Add to this some moisture, which is present in different areas of the home, and you have a perfect environment for mold growth. As such, mold has no difficulty spreading around homes.

While this is a good thing for the mold, it’s terrible for us. Having mold feed on various materials throughout the home leads to this material getting stained or destroyed.

If mold grows in your walls and floors, before long, they will begin to rot and fall apart. This is because the mold is literally eating into them (2).

If allowed to fester for long, mold can very well render a whole building structurally unsound and unfit to live in.

What Is a Mold Fogger?

A mold fogger is a device that turns mold remedial solutions from liquid to fog. While one could put such mold-killing solutions into spray bottles and mist the affected areas, foggers are more effective.

A mold fogger — by turning mold killing solutions into vapors — evenly distributes the solution. As such, it covers every single inch of the room, including the cracks and crevices we cannot reach manually.

It works by using heat to vaporize the liquid solution, which fills the room with a thick fog. Or by what is called “cold fogging,” which simply uses air pressure to vaporize the solution.

The solution will kill mold and mold spores that you can’t see. Damaged material then needs to be removed afterward to prevent the mold from returning.

Types of Mold Foggers

There are two types of foggers: thermal foggers and ultra-low volume foggers.

Thermal Foggers

A thermal fogger uses heat to vaporize chemical solutions. The heated barrel helps to produce tiny particles in large numbers, making a fog or cloud that can reach into cracks.

They often have a tank that can carry up to 40 ounces of solution with a pump that transports the solution to the heating chamber. The vapor is then expelled from the front with a nozzle.

  • Release thick and visible clouds, which enable you to see what you’re doing.
  • The size of a droplet in the released cloud can be as small as 0.5 microns, so it can penetrate small areas.
  • Use less solution to cover more areas than ULV foggers.
  • Require high energy to function.
  • There is a risk of fire because of the use of heat.

Ultra-Low Volume Foggers (ULV)

Shop This Product

Also known as a “cold fogger,” this device uses air pressure to turn chemical solutions into a mist, which is then sprayed.

With ULV sprayers, you can adjust the size of the particles for different applications.

  • Easier to operate.
  • Energy-efficient.
  • Safe to use indoors.
  • Release invisible fog, making it hard to see what you are doing.
  • Large droplet sizes ranging from 5–30 microns — less effective in penetrating cracks.
  • Take longer to cover large areas compared to thermal foggers.

Why Should You Use a Mold Fogger?

When you finally notice mold growth anywhere, sadly, it’s only the tip of the iceberg. Mold spores are microscopic, which means that you don’t see them.

Also, since mold spores are in the air, using a spray bottle is ineffective. It will definitely not kill them all.

To exterminate them, therefore, you must evenly distribute the mold-killing solution. This ensures that it fills the room, including the air where mold spores might be.

This fogger will easily blow you away. It’s an electric thermal fogger that runs on a 110-volt power supply. It easily fogs any material suitable for thermal fogging — be it oil-based or water-based.

The Smith Performance Sprayer also has the ability to create a dry fog. This means that the microscopic particles it produces won’t leave behind moisture. This means you can fog without fear of moisture pooling anywhere.

It’s very easy to use. You’ll find a trigger under the handle to turn it on and off and a knob to easily activate dry fogging. This is super comfortable as you can operate with the same hand you carry the fogger with.

Its durable aluminum container can hold up to 0.75 gallons of solution at a time. This comes with latches for extra security and to avoid tipping.

The device heats up pretty quickly. You can get it working right after preheating for a minimum of two minutes and still get it working right.

Why We Love It

Dry Fogging

It’s a wonderful feature to be able to fog without having moisture pooling at the nozzle. With the dry fog, you don’t have to worry about moisture showing up in puddles on the floor or dripping down walls.

Keep In Mind

Careful Handling

The Smith Performance needs to be handled with the same care as needed for a hot kettle. It should not be allowed too close to the body, or it could cause a slight burn.

Extension Cord

As this is an electric fogger, there is the problem of an extension cord. This needs to stay plugged in, which means you’ll have to drag the cord around to keep it powered and running.

This device uses the cold fogging mechanism, meaning that it can use either oil or water-based solutions.

It has three counter-rotating nozzles that spray a fine mist of solution, which goes up to 25 feet. This makes it better suited for smaller spaces. The powerhead can be adjusted to the angle required.

Although this fogger works great both outdoors or indoors, you may have to move around with it a lot. This is because it’s rather small and can’t shoot long distances.

Control it with a timer, and don’t worry about the solution running out as it can run dry without damage. The Fogmaster has an adjustable flow rate to keep you in control of the misting and comes with a five-year warranty.

Keep In Mind

No Hose Attachment

This fogger doesn’t have a hose attachment, so you cannot direct the flow of the mist. If you want to direct its flow, you would need to move around with the fogger.

If this is not enough, you can still go around to the opening on the other end of the crawl space and repeat the action. The mist circulating will take care of whatever is left in the middle.

Keep In Mind

Not Easy to Carry Around

This fogger is not the best for fogging on the go unless you have it in a vehicle. It is best used in one spot as it can be cumbersome to carry around.

How to Use a Mold Fogger

Mold foggers are easy to use. Once you understand how they work, you should have no trouble operating them.

  1. Properly clean the room you plan to mist with the fog first.
  2. Make sure that you remove anything that could end up damaged if they get damp, such as books and fabric.
  3. Put your chosen mold-killing solution into the tank of your mold fogger.
  4. Set the flow rate you prefer on the fogger.
  5. Place your fogger in the ideal position for spreading the fog all over the room. The center of the room is typically the best place for this.
  6. Turn on your fogger and run it for as long as you may feel is necessary. Just ensure it’s not long enough for the vapor to leave puddles or run down the walls.
  7. After you turn off your fogger, allow the room to soak up the fog for 30 minutes.
  8. Open your windows and place fans all over the room to help dry it.

As long as your chosen solution works, you can rest easy knowing that this has fixed your mold problem.
