Welcome to the Filter King affiliate programme
Filter King manufactures and ships HVAC air filters direct to US consumers — over 1,000 stocked sizes plus custom orders, made in the USA, free shipping on every order.
About Filter King
Founded in 2016 and based in Miami, Florida, Filter King operates four US manufacturing sites and delivers to customers nationwide with an average lead time of 48 hours. We serve homeowners, HVAC contractors, landlords, and commercial buyers across the US.
Air filters are replaced every 1–3 months. That makes every referral you send us a repeat customer — not a one-time sale.
What makes us different
Most filter retailers stock 50–100 sizes. We stock over 1,000 — plus we manufacture custom sizes for any non-standard dimension. That means we can serve the significant share of homeowners who can't find their size anywhere else. If your audience owns a home, there's a good chance we have their filter.
