How to Use a Dehumidifier in a Montreal Apartment (Visitor Guide): Simple Settings, Where to Place It, How Long to Run It, and How to Reduce Musty Smells

Primary keyword: Montreal dehumidifier

Quick answer: For most Montreal apartments, set a dehumidifier to about 45–50% humidity, place it in the dampest room (often the bathroom, laundry area, or basement-level space), and run it with windows closed. Empty the tank when the “FULL” light turns on. This is one of the fastest ways to reduce that musty smell after rain or long showers.

FAQ

What humidity setting should I use?

For most apartments, 45–50% is a good comfort target that also reduces musty smells.

Should I run it with windows open?

Why does it stop and show FULL?

The water tank is full (or not seated). Empty it, reinsert it fully, and restart.
