- When does Filterbuy run sales?
- Filterbuy discounts tend to appear around seasonal HVAC changeovers in spring and fall, plus Black Friday and Cyber Monday. Multi-pack and subscription pricing is where the savings usually sit, so compare per-filter cost rather than pack price.
- Where is Filterbuy cheapest?
- It varies by size and MERV rating. Filterbuy's own site often wins on bulk multi-packs, while Amazon and big-box retailers can be lower on single filters or when shipping is factored in. Check the price history on each product page before buying.
- What are Filterbuy's best products?
- The MERV 13 pleated filters are the most popular, since they capture smoke, pollen and fine dust without the airflow drop of HEPA. The 24x30x1 and 24x30x2 two-packs suit standard return grilles, and the 24x36x2 fits larger openings.
- What is Filterbuy's return policy?
- Filterbuy accepts returns on unused filters in original packaging, typically within 30 days, and custom or made-to-order sizes are usually final sale. Confirm the window on the order page, since it can differ by retailer.
- How often should Filterbuy filters be replaced?
- Every 90 days is the standard for 1-inch filters; 2-inch filters can last longer, and homes with pets or heavy dust need changes sooner. A MERV 13 filter loads faster than MERV 8, so check it monthly.
- Are there Filterbuy discount codes?
- Deal.ai doesn't list Filterbuy discount codes. It checks what Filterbuy products actually cost at every store, so a real markdown shows on this page as a deal as soon as it starts, and each product's page has its price history to tell a sale from its usual price.
