Best Mold Foggers
A mold fogger is an applicator, not a mold killer. You pour a liquid solution into its tank and the machine atomizes it into a fine mist that reaches surfaces a spray bottle cannot. Of the fogger machines we checked, three currently have a working Amazon buy box: the Concrobium Mold Control Fogger (already our top pick, 4.4 out of 5 from 331 ratings), the Createch Commander Tri-Jet ULV Fogger (corded, 4.5 out of 5 from 368 ratings), and the Vectorfog DC20+ (battery powered, but only 10 ratings so far). None of them include mold solution in the box.
The Catch: A Fogger Is an Applicator, Not a Solution
Every machine on this page does the same job: it turns a liquid into a fine, ultra-low-volume (ULV) mist so it can settle evenly across a whole room instead of just the one wall you can reach with a spray bottle. None of them come with mold control solution in the box. Concrobium's own product listing describes the fogger as a way to "apply Concrobium Mold Control solution evenly," and Createch's listing for its Tri-Jet fogger says its adjustable mist setting suits "small crevices typical of Concrobium applications." Read: buy the machine, then buy (or already own) a fogger-safe solution to put in it.
We also checked whether a single-use, no-machine-needed option exists. BioCide Labs' Mold Bomb aerosol fogger, a total-release can you set off once and discard, showed no working buy box on Amazon as of this check, with the listing marked unavailable. That leaves reusable ULV machines as the reliably purchasable route right now, which is what this page ranks.

The 3 Picks, Ranked
- Best overall: Concrobium Mold Control Fogger, adjustable flow and a track record on this site
- Best for sustained whole-room jobs: Createch Commander Tri-Jet ULV Fogger, made in USA with a 5-year warranty
- Best cordless: Vectorfog DC20+ ULV Fogger, battery powered with the longest spray distance, but weigh the thin review count
Concrobium Mold Control Fogger
Listed at $349.99 on Amazon, 4.4 out of 5 stars from 331 ratings, in stock with an active buy box. Adjustable Low, Medium, and High flow atomizes Concrobium Mold Control solution (sold separately) into a fine mist that coats basements, attics, crawl spaces, and cavities a trigger spray cannot reach. Read our full Concrobium Mold Control Fogger review for the step-by-step process and the honest cons.
Createch Commander Tri-Jet ULV Fogger
Listed at $389.99 on Amazon, 4.5 out of 5 stars from 368 ratings, in stock with an active buy box. Createch has built fogging and atomizing machines for over 30 years, and this corded unit runs an adjustable 10 to 50 micron droplet size, made in the USA with a 5-year manufacturer warranty. The listing itself names mold control as an intended application and calls out settings sized for "concrobium applications," so it is built with the same solution in mind as our top pick.
Vectorfog DC20+ ULV Fogger
Listed at $626.55 on Amazon, in stock with an active buy box. A 21.6V rechargeable battery and 1250W motor power this handheld unit for up to 45 minutes of runtime with no cord, an adjustable 5 to 50 micron mist, and a spray distance up to 26 feet, the longest reach of the three. The honest caveat: only 10 ratings so far, at 3.7 out of 5, a much thinner track record than the other two picks. Weigh that against the convenience of not being tethered to an outlet in a crawl space.

Which One Should You Actually Buy
Match the machine to the job, and remember every one of them ships without solution:
You already trust Concrobium, or you want the pick with the longest track record on this site. Get the Concrobium Mold Control Fogger. It pairs directly with the EPA-registered, bleach-free Concrobium Mold Control solution, and we have a full step-by-step review of how to run it.
You are treating a big, damp basement or a post-leak attic on a repeat basis. The Createch Commander Tri-Jet is corded, so it runs as long as your outlet does, and its higher rating count gives you more owner data points to go on. Made-in-USA build and a 5-year warranty matter if you expect to use this more than once.
You need to fog a space with no outlet, like a detached shed or a crawl space you cannot run a cord into. The Vectorfog DC20+ is battery powered and reaches further, but go in knowing only 10 buyers have rated it so far. If that is too thin a sample for a $600-plus purchase, rent a corded unit for a one-time job instead.
Skip a fogger machine entirely if your mold problem is one visible patch under about 10 square feet (a spray bottle of the same solution does the job for a fraction of the price), if the growth has rooted into porous drywall or wood (that needs cutting out and replacing, not fogging), or if you have not yet fixed the moisture source (fog a leaky room and the mold returns, fix the leak first).
Whichever fogger you choose, wear an N95 respirator, gloves, and goggles, remove or cover paper products and electronics before you start, and let the mist settle for 15 to 20 minutes before you go back in to wipe surfaces. This page provides cleaning and PPE guidance only, not medical advice.

Get Early AccessFrequently Asked Questions
Does a mold fogger kill mold by itself?
No. A fogger is an applicator, the same way a paint sprayer is not paint. You pour a liquid mold control solution into the machine's tank, and the fogger atomizes it into a fine mist that coats walls, floors, and ceilings evenly. The mold-killing work is done entirely by the solution you choose, not the machine.
What solution should I put in a mold fogger?
Use a liquid labeled safe for fogging or ULV application, such as Concrobium Mold Control, which is EPA-registered and bleach-free. Check your specific fogger's manual before adding any chemical, since not every machine is built for the same solutions. Plain water alone will not treat mold, it just tests the equipment.
Is a fogger better than a spray bottle?
For one visible patch of mold under about 10 square feet, a trigger spray of the same solution is cheaper and just as effective. A fogger earns its price when the job is a whole room, an attic, a crawl space, or wall and ceiling cavities you cannot reach by hand. Match the tool to the size of the space, not the size of your budget.
Are total-release mold bombs the same as a fogger?
No. A total-release aerosol, sometimes called a mold bomb, is a single-use can you set off and discard. A ULV fogger is a reusable machine with an adjustable flow rate that you refill and reuse. As of this writing, the leading single-use mold bomb aerosol was out of stock on Amazon with no working buy box, so a reusable fogger plus a bottle of solution is the more reliably purchasable route.
Do I need protective gear to run a fogger?
Yes. Wear an N95 respirator, gloves, and goggles, since working in a moldy space disturbs spores and fogging fills the air with fine mist. Leave the room during and immediately after fogging, and let the mist settle for 15 to 20 minutes before you go back in to wipe surfaces. This app and this guide provide cleaning and PPE guidance only, not medical advice.
