Buying online from Filterbuy is the most reliable way to handle home air filter replacement without leaving the house. Local stores usually stock only common sizes and a limited range of MERV ratings, so selection and quality can be inconsistent.

Reordering is simple from your order history, and you can save with multi-packs or set Auto Delivery so replacements arrive on schedule.
Most homes place the return filter in one of two spots: a return grille on a wall or ceiling in a hallway or living area, or a filter slot or door at the indoor unit in a closet, attic, basement, or garage. Some homes have more than one return. Check each location.
Use the nominal size printed on the frame. If there is no label, measure the opening in inches and round to the nearest whole number, then order that nominal size. Nominal and actual sizes differ slightly by design. If the fit is loose or air can bypass the edges, order a custom size for a snug, efficient seal.
Choose from standard or custom sizes for a precise seal, then select the MERV level your system supports (8 for everyday dust and pollen, 11 for pets or allergies, 13 for higher filtration in compatible systems). If household smells are a concern, the Odor Eliminator option adds activated carbon.
Every Filterbuy filter is made in the USA and ships fast and free, and you can keep changes on schedule with convenient Auto Delivery.
Check monthly and replace every 1–3 months. Change sooner with pets, allergies, smoke events, or heavy dust. Staying ahead of home air filter replacement keeps airflow steady, protects equipment, and helps your HVAC system perform as designed.
