Frequently Asked Questions
How often should I change pleated furnace filters during summer and smoke season?
Change 1" pleated filters every 30–90 days depending on MERV level, HVAC load and indoor conditions. During smoke events or heavy pet use change closer to 30 days; for light use and cleaner air, 60–90 days may be fine. Buying six-packs makes regular swaps easier.
Will a higher-MERV filter restrict my HVAC airflow?
Higher MERV filters can increase resistance in older or undersized HVAC systems. MERV 11 is effective against smoke and allergens but check your system's specifications or ask an HVAC tech if your unit is older. If you notice reduced airflow or efficiency after upgrading, switch back to a lower-MERV filter or have the system inspected.
My filter slot is tight — how do I know which product will fit?
Always use the product's listed actual size rather than nominal dimensions. Measure the slot and compare to the filter's actual size and thickness (0.75" vs 0.81" are common differences). Look for buyer notes about fit and consider a slightly smaller actual dimension if your slot is tight.
