Due to the dry winter weather, we use humidifiers to maintain our health and the quality of interior materials such as hardwood floors. Most homes have a drum-type or drip-type humidifier mounted on the side of the furnace. It usually has a water supply from a small line connected to a nearby water line.

During the spring and fall, relative humidity levels can be set to approximately 40 per cent but should be adjusted to less during the coldest winter days. If ice or excessive condensation appears on your windows, reduce the humidity even more. It may even require turning off entirely in extreme cold temperatures, when excessive condensation or ice is forming on windows.

Over time, the repeated evaporation of water will leave mineral deposits in the humidifier. Dust and debris circulating through the furnace will also deposit in the humidifier. This debris can create  bacteria so it’s important to clean the humidifier on a regular basis.

To clean your humidifier, first turn off the water supply, and then switch the duct damper position to off, or “summer” mode.

Next, carefully remove the cover and vapour pad. Remember to inspect the drain hose and vapour pad for mineral deposits, and check their overall condition. Use your kitchen sink to soak the vapour pad in a solution of equal parts vinegar and water to clean.

Pat the vapour pad dry, before reinstalling and replacing the cover.

Finally, return the duct damper to its original position, and turn the water supply back on. That’s it, you’re done!

We recommend cleaning your humidifier seasonally.
