SuperHandy Backpack Mist Duster
Best Mold Fogger for Mobility
This portable backpack fogger is one that you can rely on. It has a 20-feet horizontal spray range and a 4.9 to 6.5-feet vertical spray range, so it’s suitable for smaller places, but you can use this outdoors, too. This versatile mold fogger is great for controlling mold and mildew, as well as a variety of other things.
For example, you can use this to disinfect hotels, schools, homes, theatres, malls, hospitals, and much more. It’s designed for indoor fumigation. However, it’s also designed for pesticides outdoors in yards, gardens, greenhouses, and farms.
You can also use this to water fruit and flowers. It’s an all-in-one product that you’ll get a lot of use out of, whether you’re using it personally or commercially!
When you’re using it, you’ll be thankful you purchased such a comfortable and lightweight option that is easy to wear for a few hours at a time.
What We Like
Indoor and Outdoor Use
As mentioned, this is a top choice for its indoor and outdoor capabilities. Whether you’re disinfecting, sanitizing, or even just watering items — you can use this wherever you go!
Lightweight at 10 Pounds
Wearing this backpack is a breeze, not just because it’s comfortable but because it’s lightweight at 10.43 pounds. A huge bonus is that it has a generous tank capacity of three gallons and a cushioned air mesh pad for maximum airflow, making fogging comfortable.
Easy to Use
Even for beginners, this is an excellent product to start with. It’s easy to dilute your solution according to the product label with this tank. It has markings and a funnel, so you can easily fill it up without heat, exhaust, or loud noises.
Of course, you should use PPE when applicable since residual liquid can rise afterward. This can lead to irritated skin, respiratory issues, or other problems, depending on your solution.
Delivers a Fine Mist
This delivers a fine mist with droplets of zero to 50 microns. This helps to minimize dust and keep up humidity which is ideal for asbestos abatement.
What We Don't Like
Noisy and Irritating
Some customers find the machine a bit too loud. To help you decide, does this outweigh the advantages? Think it over.
The Cord Is Annoying
You lose some flexibility when you choose a corded option over a battery-powered one. If you need more wiggle room, this one might get on your nerves.
|Attachments Included||ULV fogger|
|Item Weight||10.43 pounds|
|Tank Size||3 gallons|
|Particle Size||0 – 50 microns|
Smith Performance Sprayers FT982 Electric Thermal Fogger
Best for Dry Fogging
This fogger will easily blow you away (not literally). It’s an electric thermal fogger that runs on a 110-volt power supply. It easily fogs any material suitable for thermal fogging, whether oil-based or water-based.
The Smith Performance Sprayer also can create a dry fog. This means that the microscopic particles it produces won’t leave behind moisture. 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.
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.
What We Like
Dry Fogging Feature
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.
Ease of Use
This fogger is incredibly easy to use with its well-placed controls and simple, one-structure build. This allows you to use it with one hand easily.
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.
Heats Quickly, Lasts a While
This machine heats up in only a few minutes. You’ll get ours of use out of it before you need to refill it.
Impressive and Complete Coverage
This device atomizes the chemical to create a super fine fog. It can get into nooks, crannies, and other tiny spaces, providing complete coverage.
What We Don't Like
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 Included
As this is an electric fogger, there is the problem of an extension cord. This needs to stay plugged in, so you’ll have to drag the cord around to keep it powered and running.
|Type||Electric thermal fogger|
|Item Weight||6 pounds|
|Tank Size||0.75 gallons|
|Particle Size||10 – 50 microns|
Concrobium 200-620810 Mold Control Fogger

It comes with a concise list of instructions on how to use the device. Use alongside Concrobium Mold Control Formula to effectively eliminate and prevent mold without harmful chemicals.
Using the cold fogging method, this device creates a very light and even mist. The generated mist sufficiently covers the room it’s being used in. It’s terrific for indoor use, shooting the spray as far as 20 feet.
What We Like

What We Don't Like
Could Have Damaged Nozzles
While this is a great fogger, some reviewers report that the nozzle arrived damaged. In this instance, you would need to call the company for a replacement.
Not the Most Secure Device
The fastening clips on the device aren’t the strongest. After a few uses, they might come loose. Then liquid can leak out.
|Type||ULV cold fogger|
|Item Weight||8 pounds|
|Tank Size||1 gallon|
|Particle Size||10 – 30 microns|
Treasure Hunter Silver Bullet Non-Thermal Mold Fogger
Best for Smaller Spaces
The Triple Jet Cold ULV is a durable product you can rely on. Made by Ten Green Fingers, it’s outfitted with stainless steel. The body is made of sturdy aluminum.
This device uses the cold fogging mechanism, meaning 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 40 feet. This makes it better suited for both smaller and bigger spaces. You can adjust the valve to fit your need.
Although this fogger works great outdoors or indoors, you may have to move around with it a lot. This is because it’s rather small and handy at 5.72 pounds.
The Ultra Low Volume non-thermal fogger has an adjustable flow rate to keep you in control of the misting and comes with a warranty.
What We Like
Small and Portable
This fogger is small and doesn’t take up much space. It’s not very heavy (5.72 pounds) and can easily be carried from room to room. Therefore, you can store it and use it regularly without stress.
Compatible With Oil and Water-Based Solutions
This is a cold fogger, so it doesn’t restrict you to water-based solutions. You can put in an oil-based solution, which would make a fine mist without causing problems for the machine.
Value for Money
This has been loved by many considering its multi-functionality and its price point. Many had pointed out that it does its job pretty well without a fuss.
Not only does this control mold and mildew, but it also sterilizes, delivers pest control, and can output Concrobium Mold Control.
What We Don't Like
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 need to move around with the fogger.
Design Isn’t Durable
Despite the robust pump and stainless steel elements, the overall design isn’t super durable. Customers found it was already buckling under pressure after only a few hours. The seal isn’t great, and the fastening clips aren’t tight enough.

What We Like
Easy to Use With Convenient Switch
This fogger is incredibly easy to use with a simple on/off toggle switch. Once you turn it on, it jets the mist away from you, giving you plenty of time to leave the area.
Great for Crawl Spaces
It’s ideal to use this fogger for crawl spaces. All you need to do is turn it on directly facing the opening of the crawl space. The powerful motor will jet the mist up to 30 feet in.
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.
You can use this for removing mold and mildew. But it’s also great for removing insects and other pests, eliminating odors, and sanitization.
High Standard Construction
This fogger is made in the USA and comes with a five-year warranty. You can assure that this is made with high standards and is backed by a reliable guarantee.
What We Don't Like
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.

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.
Besides its unpleasant appearance and smell, mold is also hazardous to your health. Therefore, it’s vital to eliminate mold and mildew from your living space as soon as you notice it.
1. 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 eye, skin, and throat irritation.
Those with preexisting health issues, such as chronic lung disease, can have 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 them (1).
2. 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 present in different areas of the home, and you have a divine environment for mold growth. As such, mold has no difficulty spreading around homes.
Having mold feed on various materials throughout the home leads to this material getting stained or destroyed.
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 spores that you can’t see. Damaged material must 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.
A thermal fogger uses heat to vaporize chemical solutions. The heated barrel helps to produce tiny particles in large numbers, making fog or clouds that can reach into cracks.
They often have a tank carrying 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 that 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)
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 and can be operated remotely.
- More energy-efficient.
- Safe to use indoors since they don’t heat up.
- You can apply fungicides via this type of fogger and use them on crops.
- Release invisible fog, making it hard to see what you are doing.
- Large droplet sizes ranging from five to 30 microns are less effective in penetrating cracks.
- Take longer to cover large areas compared to thermal foggers.
Why Should You Use a Mold Fogger?
Sadly, it’s only the tip of the iceberg when you finally notice mold growth anywhere. 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.
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.
- Properly clean the room you plan to mist with the fog first.
- Make sure you remove anything that could end up damaged if they get damp, such as books and fabric.
- Put your chosen mold-killing solution into the tank of your mold fogger.
- Set the flow rate you prefer on the fogger.
- 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.
- Turn on your fogger and run it for as long as you may feel is necessary. Ensure it’s not long enough for the vapor to leave puddles or run down the walls.
- After you turn off your fogger, allow the room to soak up the fog for 30 minutes.
- Open your windows and place fans around 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.
Safety Tips for Using a Mold Fogger
When using a mold fogger, there are some critical steps to ensure you stay safe during the process. Some of them are:
- Read the instructions on how to mix your solution properly to avoid chemical accidents.
- Wear a mask and a protective suit to protect yourself from the chemicals being sprayed.
- Keep children and pets away from the area being misted.
- Try not to mist too long to avoid puddles and moisture drips on walls.
