When was the last time you changed your furnace filter? If you can’t remember, it’s probably overdue!
A clogged filter makes your HVAC system work harder, leading to higher energy bills, more dust, and even potential damage to your furnace.
So, how often should you replace your furnace filter?
The No-Guesswork Guide to Replacing Your Filter
The optimal schedule for changing your furnace filter will depend on your specific home and lifestyle, but here’s a general rule of thumb:
- Every 1-2 months: If you have pets, allergies, or a very busy household, more frequent replacements may be needed.
- Every 3 months: Most homes with standard air quality should have their furnace filters replaced at least once per season.
- Every 6-12 months: If you use high-efficiency filters or don’t run your system often, you may be able to get away with changing your filter less often.
PlumbPRO Tip: Not sure if your furnace filter is ready for a replacement? Hold it up to the light. If you can’t see through it, it’s time for a change!
What Factors Affect My Furnace Filter’s Lifespan?
Not all furnace filters need to be replaced on the same schedule. Some factors help filters last longer, while others make more frequent changes necessary.
Factors That Can Help Your Filter Last Longer
If these factors apply to your home, you may be able to replace your furnace filter less often:
- Minimal HVAC Use: Your filter won’t collect as much debris if it’s not running. Homes that don’t require year-round use of their HVAC system can benefit from longer filter lifespans.
- High-Quality Filters: HEPA or high-MERV filters can last longer than basic fiberglass ones.
- Small Household: Fewer people means less foot traffic causing dust to circulate in the air.
Factors That Can Shorten Your Filter’s Lifespan
Check your furnace filter more often if these factors apply to your household:
- Pets: Pet hair and dander can clog filters quickly, requiring replacements as often as every four weeks.
- Allergies or Asthma: Monthly replacements can be helpful if you require your air to stay fresh and allergen-free.
- Poor Air Quality: If you live in an area with poor air quality, such as near a construction site or in a particularly dry climate, your filter may clog faster.
