Frequently Asked Questions
How often should I replace furnace filters on a subscription?
Replace 1" filters every 60–90 days under normal conditions; 2" filters can often stretch to 90 days; for smokers, pets, or high pollen areas consider 30–60 day intervals. Follow your HVAC manufacturer's recommendations and check filters visually—if they look loaded, swap sooner.
Will a higher MERV rating harm my HVAC system?
Very high MERV filters can increase resistance in older or undersized blower systems. MERV 8–13 are common household ranges; consult your HVAC manual or technician before moving above MERV 13. Choosing a filter with good pleat design and not letting it become clogged helps maintain airflow.
How do I ensure I get the right size in a subscription?
Measure the filter slot and the existing filter's actual dimensions (not just nominal). Many products list actual sizes—compare those to your measured slot. When setting up a subscription, verify the ASIN and size before confirming and choose a seller or plan that allows size changes if needed.
