In the Edmonton area, you should typically change your furnace filter every 1 to 3 months—but it depends on your home and lifestyle:
Every 1 month if you have multiple pets, allergies, or live in a dusty area
Every 2 months for average homes with one pet or light allergies
Every 3 months in smaller homes with no pets and minimal dust
More often during heavy-use seasons, like winter (heating) and summer (if you use central AC)
Filter size and quality also play a role—smaller or lower-MERV filters usually need changing more frequently.
If you’re tired of remembering when to replace them, our ProComfort Dual and ProHeating Memberships offer an Air Filter Delivery Add-On. We’ll deliver the right filters to your door on schedule—so your home stays clean, your air stays fresh, and your HVAC system runs at its best without any guesswork.
