Humidifiers make many homes in Alberta’s dry climate more comfortable, but how do they work and what should you know before buying one? Whether you’re adding a humidifier to your HVAC system for the first time or replacing an old unit, the Action Furnace team is here to help you learn more about these simple but often essential systems.
We’ve worked with whole home and steam humidifiers for years, and we’re happy to share our professional expertise with you to help make buying your next humidifier an easier process. Learn about humidifier prices, installation times, maintenance, and more below.
How Does a Humidifier Work?
The basic science behind an evaporative humidifier is really simple:
- The humidifier’s tank contains water, which is used to soak the filter and make it damp.
- Your HVAC’s fan blows air through the damp filter, causing the water on it to vapourize.
- The water vapour then enters the air circulating throughout the home.

There are two main kinds of evaporative humidifiers—flow-through and drum versions. Flow-through humidifiers move fresh water through the system on a continuous basis to keep the filter wet, which drains away afterwards. Drum humidifiers are designed for the filter to soak up standing water from a pan.
Some humidifiers introduce variations on this concept. For instance, steam humidifiers use electricity to heat up the water in the tank until it evaporates, warming the air as well as adding moisture to it.
What Should You Consider When Buying a Humidifier?
Because the air in Alberta homes is typically so dry, adding a humidifier to your HVAC is a great way to make the interior more comfortable. But to get the most from your new humidifier, you’ll want to consider the following:
Humidifier Size
Humidifiers are designed with a range of capacities to accommodate the needs of different buildings. There are two main points you’ll need to consider to determine the right size humidifier for your home:
How Big Is Your Home?
The size of the area you’re trying to add moisture to plays a key role in how much capacity your new humidifier will need. Use the chart below to find out how much water your humidifier should hold to work properly in an average home:
| Home Size (square ft) | 1000 | 1500 | 2000 | 2500 | 3000 |
| L per day of water | 11.35 | 20.82 | 30.28 | 39.75 | 49.21 |
To figure out how many litres of water per day your humidifier uses, you’ll need to know its output (generally measured in ml/hr). Then convert this number to L and multiply it by 24.
How Insulated Is Your Home?
The chart above assumes your home is average, but the capacity your humidifier will need can vary depending on how well or poorly insulated it is.

Here’s the chart for homes with loose insulation:
| Home Size (square ft) | 1000 | 1500 | 2000 | 2500 | 3000 |
| L per day of water | 15.14 | 26.50 | 37.85 | 49.59 | 60.95 |
And here’s the chart for tightly insulated homes:
| Home Size (square ft) | 1000 | 1500 | 2000 | 2500 | 3000 |
| L per day of water | 5.30 | 12.11 | 18.55 | 24.98 | 31.42 |
The charts above apply to whole-home humidifiers connected to your HVAC system. Not sure how well insulated your home is, or how to figure out how much water per day the humidifier you’re considering uses? Contact our comfort advisors and let us recommend a humidifier that will meet your home’s needs.
Humidifier Type
You’ll also want to give some thought to the kind of humidifier you purchase. We’ve touched on the two main kinds of whole-home humidifiers above—evaporative and steam humidifiers—but which one is best for you?
Evaporative Humidifiers
Evaporative humidifiers generally cost less up front than steam humidifiers, but aren’t quite as efficient. They also need to be cleaned on a more regular basis to prevent the accumulation of mould (although cleaning is easy).
Flow-Through vs. Drum Humidifiers
In our experience, most Calgary homeowners opt for flow-through humidifiers instead of drum models, since the constant flow of water through the system flushes out minerals and helps them stay clean for longer periods of time. Drum humidifiers are more prone to mould buildup as well, so they need to be cleaned more regularly.
Steam Humidifiers
Investing in a steam humidifier requires less maintenance in the long run and will use less water over time, although they typically cost more at the front end.
Where to Install Your Humidifier
Whole home humidifiers are generally connected to your home’s furnace. The humidifier will either be connected to the cold-air return duct or the hot air supply duct, depending on what kind of humidifier it is. When you contact us to have a new humidifier installed, we’ll be able to tell you the best way to connect it to your existing HVAC system.
Whole Home vs. Portable Humidifiers
Not all humidifiers are whole home versions—some humidifiers are standalone units with their own water tanks, which are generally plugged into electrical outlets and set up in the rooms they’re intended to moisturize. But these portable units lack the ability to add moisture effectively throughout the air in a home, meaning you’ll use a lot of electricity just to improve the comfort in a small space. We recommend investing in a whole home humidifier for the most comfortable and cost-effective experience.
Humidifier Cleaning & Maintenance
You’ll have to do some maintenance to keep your humidifier in good condition, depending on the kind you have. Here are the basics:
- Every week or two while your humidifier is in use, power it down and remove the filter.
- Visually inspect the filter for mould, which can indicate that it’s time to replace it with a new one.
- Place the humidifier pad into a bucket of white vinegar or a solution of bleach and water. Let it stand for 20 minutes to an hour.
- Scrub the inside of the humidifier with a soft-bristled brush afterwards and rinse it out, allowing all components to dry before using the humidifier again.
