The best Halloween fog machines, ranked on output against the circuit they share
A fog machine is a heater with a pump. The wattage on the box decides whether it runs beside your lights or trips the breaker they share.
By Sawyer V. · Published
Fog is the cheapest special effect in Halloween decorating and the one most likely to take the rest of the display down with it. Every fog machine works by pumping fluid through a heated block, and the heater is where almost all of the wattage goes — which makes a fog machine one of the largest single electrical loads in a yard.
So this page ranks on output against draw. Five machines below, compared on the watts, the published fog output, the tank size and the remote, with the amp arithmetic that tells you whether each one can share a circuit with your lights.

- A published output figure and a published tank size — the two numbers that decide how long the fog lasts
- At 3.3 A it shares a display circuit with lights and a projector without drama
Watch out
- A 15 ft wired remote means someone standing near the machine; the wireless controller is extra
- One pint is a short night at full output — keep a second bottle of fluid by the door

#2 — Filling a whole front yard
BORGOVA 1000 W fog machine, 1 L tank, timer
5,000 CFM and a 1 L tank, with a timer
8.5
/ 10
The pick for a big yard, costed properly. Put it on its own circuit and it does more than anything else here; share it with the lights and you will be resetting a breaker.

Good
- The only machine here that publishes output, throw range, tank size and a timer together
- A 1 L tank is roughly twice the pint on the Froggy's, which matters over a three-hour evening
Watch out
- 8.3 A is more than half the 12 A continuous budget on a 15 A circuit — it needs a circuit of its own or very little else on it
- 5,000 CFM on a small porch is a whiteout, not an atmosphere
Specs from the Amazon listing (ASIN B0CMWF21KV), verified 2026-09-11.
#3 — Triggering from inside the house
VIRFUN 400 W fog machine, wireless and wired remote
Remote range up to 45 ft
8.5
/ 10
The pick if you want to time the fog to a trick-or-treater arriving. The remote range is the feature; the missing tank size is the catch.
Published specifications

How we ranked these
Published output first, because it is what you are buying. Then circuit friendliness, because a machine that trips the breaker produces no fog at all. Then tank size, remote and how completely the listing documents itself. Amp figures are our arithmetic from the published wattage at 120 V; nothing here was measured by us.
| Machine | Watts | Amps at 120 V | Output | Tank | Remote |
|---|---|---|---|---|---|
| Froggy’s Fog 400 | 400 | 3.3 | Up to 2,000 CFM | 1 pint | 15 ft wired |
| BORGOVA 1000 | 1,000 | 8.3 | 5,000 CFM | 1 L | Wireless + timer |
| VIRFUN 400 | 400 | 3.3 | About 2,000 CFM | Not stated | Wireless + wired, 45 ft |
| FANSTGEQ 1000 | 1,000 | 8.3 | About 5,000 CFM | Not stated | Wireless + manual |
| 1byone 400 | 400 | 3.3 | Not stated | Not stated | Wired |
Amps are our arithmetic: published watts divided by 120 V. Output is the manufacturer's own figure; there is no common test standard behind CFM claims in this category.

The circuit arithmetic, before anything else
This site uses one rule for every continuous load: keep it at or under 80 percent of the circuit rating. On an ordinary 15 A household circuit that is 12 A, or 1,440 W, and a Halloween display is a continuous load for five or six hours a night.
The arithmetic
- 15 A circuit x 0.8 = 12 A continuous = 1,440 W
- 400 W fog machine / 120 V = 3.3 A = 28% of the budget
- 1,000 W fog machine / 120 V = 8.3 A = 69% of the budget
- 12 A - 8.3 A = 3.7 A left for everything else on that circuit
A 400 W machine shares a display circuit comfortably. A 1,000 W machine leaves 3.7 A for everything else — roughly one inflatable blower and a few light strings — and needs a circuit mostly to itself.
The practical consequence: if you want the big fog, find the big fog its own outlet on a separate breaker. The method for working out which outlets share a breaker, and what else is on them, is on Halloween yard display power, and the rule itself on how many amps.
Output claims, and how far to trust them
CFM — cubic feet per minute — is the only output figure this category publishes, and it is a manufacturer claim with no shared test behind it. Compare it within a wattage class rather than across brands with any precision.
What the numbers do tell you is the class. The 400 W machines publish around 2,000 CFM; the 1,000 W machines publish around 5,000. That two-and-a-half-times difference is real and visible: a 400 W machine makes a patch of fog around a feature, and a 1,000 W machine makes a yard of it. On a porch, the bigger machine is too much.
Tank size and the length of an evening
Two listings publish their tank. The Froggy’s Fog holds a pint and the BORGOVA holds a liter.
The arithmetic
- 1 US pint = 16 fl oz = about 473 mL
- 1 L = 1,000 mL
- 1,000 / 473 = 2.1
The BORGOVA carries just over twice the fluid. No listing publishes consumption per minute, so we do not print a run time — but a bigger machine also empties a tank faster, so keep a second bottle of fluid by the door either way.
Fog goes where the wind goes
Outdoors, fog is a weather problem. On a still night it pools in low ground and hangs around a feature; with any breeze at all it streams sideways and disappears. Put the machine upwind of what you want to shroud, not beside it.
The other physical fact worth knowing: heated fog rises as it leaves the nozzle. Fog that hugs the ground needs chilling, which is a different kind of machine, and none of the five here claim to do it. What these make is a haze at head height that settles as it cools.
Fog is what makes light visible
On its own, fog in the dark is invisible. Put a light through it and every beam becomes a solid object — which is why a fog machine is the cheapest upgrade to a display that already has a spotlight or a projector.
Aim a colored light across the fog rather than into it, and keep the light low. The method is on Halloween display lighting, and the projector choice on Halloween projectors. Fog around a graveyard of foam tombstones is the classic pairing for a reason.
The remote, and who is holding it
A 15 ft wired remote means standing within 15 ft of the machine. That is fine if the machine sits by the door; it is useless if the machine is out in the yard. The VIRFUN publishes a wireless range of up to 45 ft, which is the difference between firing it from behind the front door and firing it from a bush.
The BORGOVA’s timer is the other answer: bursts on a schedule, nobody holding anything. That is the right mode for a display that runs all evening; on-demand is the right mode for timing fog to someone arriving.
Rain, cords and where the machine sits
None of the five publishes a weather rating. That puts every one of them under cover — on a porch, under an overhang, or inside a ventilated box — and never directly on wet ground. Plug into a GFCI outlet on an outdoor-rated cord, and keep the connection off the grass. The general rules are on outdoor light safety and extension cords.
Indoors, fog from these machines can set off some smoke alarms. Keep it well away from detectors, or keep it outside where it belongs.
Putting it away in November
Store the machine empty, upright and dry, with the remote bagged and taped to it, and the fluid in a sealed bottle rather than in the tank. Then it goes in with the rest of the season — Halloween decoration storage covers the awkward shapes this one sits beside.
Questions
›How many watts should an outdoor Halloween fog machine be?
400 W for a porch, a walkway or a single feature; 1,000 W for a whole front yard. The 400 W machines here publish around 2,000 CFM and the 1,000 W machines around 5,000. Size it to the space, and cost the wattage against your circuit before you buy.
›Can a fog machine run on the same circuit as Halloween lights?
A 400 W machine draws 3.3 A, which shares a 15 A display circuit comfortably. A 1,000 W machine draws 8.3 A — 69 percent of the 12 A continuous budget — and leaves very little for anything else. Give the big machine its own breaker.
›How long does a fog machine tank last?
No listing here publishes a consumption rate, so we do not print a run time. Two publish their tank: one pint and one liter. A bigger machine empties its tank faster, so keep a spare bottle of fluid on hand either way.
›Can you use a fog machine outside in the rain?
None of the five here publishes a weather rating, so keep every one of them under cover and off wet ground, plugged into a GFCI outlet on an outdoor-rated cord.
