Clean Comfort HS29-208 Steam Humidifier | Installation in Montreal, Laval, Longueuil, South Shore and North Shore
Is it the right size for your home?
It produces 28.7 gallons of steam a day, enough to humidify about 3,400 sq ft (our estimate). Pick your home's living area.
It's the right size.
For a 1,500 to 2,500 sq ft house, it's within its range. It will run at part load on ordinary days and keep a reserve for the coldest days.
AirGreen estimate. Clean Comfort publishes no area in sq ft for this model. For an average-construction home, we count 120 sq ft per gallon a day, the ratio in AprilAire's and Lennox's tables. Older or leaky house: go one size up; our estimator confirms it on site.
What it does, in numbers
$135
Electricity per winter
It rarely runs at full output
Same period for every line, November 1 to March 31 (150 days), at Hydro-Québec's Rate D second tier (11.142 ¢/kWh). At full output it costs $0.42 an hour.
Full output with a heat pump. It heats its own water, so it doesn't depend on the air temperature in the ducts.
Output and current: manufacturer's spec (28.7 gal/day at 208 V and 18.3 A), hence 3.8 kW. Cost per winter: 2,000 sq ft house with 9 ft ceilings, 0.35 air changes per hour (the same basis as our air exchangers), −5 °C and 75% humidity outside on average, 35% targeted indoors, minus the moisture a family of four already produces. A leakier house, or a higher setting, costs more.
What you should know about this one
Published, verifiable figures, not brochure claims.
28.7 galWhat it produces per day, at full output
About 109 litres of water turned into steam in 24 hours. The control runs it to match the humidity you set: it rarely runs flat out, except in very cold weather.
SteamIt doesn't depend on warm air
An evaporative humidifier needs warm air to evaporate the water from its pad. Behind a heat pump, which blows cooler air than a furnace, it produces less. This one heats its own water: same output, whatever the system.
0No pad to replace every fall
The electrodes and the cylinder wear according to water hardness. We check them at the yearly service, along with the rest of the system.
208 VBuilt for 208 V
The 208 V version draws 18.3 A and needs a 25 A breaker; its HS29-240 twin draws 15.9 A on 20 A. Same output: 28.7 gal/day.
AutoIt adapts to your water
Automatic fill and drain; its auto-adaptive routine sets the flushing to suit the house's water.
30 to 80 psiThe water pressure it needs
It works with water pressure from 30 to 80 psi. Every HS model shares the same 11.4 × 6.9 × 21.4 in. cabinet.
UpkeepWhat gets replaced, and when
HSP-2573990 cylinder, the same as the HS22.
35%The humidity to aim for in winter, at most
At −7 °C, no more than 35%; at −18 °C, no more than 25%. Above that, the moisture condenses on the windows. The control adjusts for you if it has an outdoor sensor.
5 yearsThe parts warranty
Parts are covered for 5 years by the manufacturer. We register the warranty in your name at start-up.
What it needs on site
A steam humidifier needs an electrical circuit of its own. Our estimator checks the panel, the water supply and the drain before ordering.

Clean Comfort HS29-208: 28.7 gal/day of steam, built for 208 V
The HS29-208 is a steam humidifier from Clean Comfort's HS series. An electrode cylinder makes the steam, which is injected into the ducts; furnace heat plays no part, which suits a home behind a heat pump. It gives 28.7 gal/day. Clean Comfort publishes no area; by our estimate, it suits about 3,400 sq ft for average construction.
Why a 208 V version
On 208 V it draws 18.3 A for 3.8 kW and needs a 25 A breaker. Its twin, the HS29-240, draws 15.9 A on 20 A, for the same output. You pick the version that matches your supply. It shares the HSP-2573990 cylinder with the HS22 and the 11.4 × 6.9 × 21.4 in. cabinet of every HS unit, at 16 lb.
On site and for upkeep
Plan for a dedicated 25 A, 208 V circuit, a water line at 30 to 80 psi and a drain. Fill and drain are automatic; the auto-adaptive routine adjusts the flushing to the water. The cylinder is replaced when it is worn out.
In-home estimate
No installed price without seeing the house. Our estimator checks the heating system, room in the panel for a 25 A, 208 V circuit, the water and the drain, then we give you a price. Service in Montréal, Laval, Longueuil, the South Shore and the North Shore. Call 514 316-2973.
