Register your air conditioner once. FilterDrop looks up the right filter size and sends it on your manufacturer's recommended schedule — so you never have to think about it again.
Three steps to never thinking about your AC filter again.
Tell us your AC brand, model, and install year. We look up the right filter size and replacement schedule automatically.
Choose 30, 60, or 90-day delivery based on your household's needs. Cancel or pause any time.
The right filter ships to your door on schedule. No reminders, no guessing — just cleaner air.
All plans include the right-sized filter for your unit, free shipping, and a unit profile dashboard.

When you register your AC unit, you can optionally contribute anonymized data to help HVAC contractors and manufacturers improve their products and services. Always opt-in, always anonymized, and you can opt out any time from your dashboard.
