Frequently Asked Questions
How often should I change MERV 13 furnace filters?
For most households, change 1" MERV 13 pleated filters every 60–90 days. Thicker 2" filters can often last 3–6 months or longer depending on household dust, pets and smoke exposure. Inspect filters monthly during high-use seasons and replace when visibly dirty or if airflow seems reduced.
Can a MERV 13 filter damage my HVAC system?
Not usually — MERV 13 is safe for many residential systems, but some older or low-capacity HVAC units may struggle with higher-resistance filters. If your manufacturer or HVAC pro recommends a lower MERV, follow that. Check airflow after installing a higher-MERV filter and replace more frequently if the system shows strain.
Should I buy multipacks or use subscription delivery?
Multipacks typically lower per-filter shipping cost and ensure you have spares on hand. Subscriptions add convenience and can lock in regular deliveries; before subscribing, confirm the seller ships the exact actual size you need and that the cadence matches your preferred change interval.
