Frequently Asked Questions

What size air filter do I need?

Check the size printed on the frame of your old filter, or measure the length, width, and depth in inches (round up if needed). Aerterra filters are labeled by nominal size, like 16x25x1, so you can match it directly to your return vent or furnace opening.

How often should I replace my Aerterra filter?

Most 1-inch filters should be replaced every 60–90 days, depending on your home's air quality, pets, and HVAC usage. Thicker 4-inch filters typically last 6–9 months. A subscription ships a fresh filter automatically on the schedule that fits your home.

What does the MERV rating mean?

MERV (Minimum Efficiency Reporting Value) measures how well a filter captures airborne particles, on a scale of 1–16. Higher MERV ratings capture smaller particles like pet dander, smoke, and bacteria. We offer MERV 8, 11, and 13 options depending on how much filtration your home needs.

What are Aerterra filters made from?

Aerterra filters are made from renewable, plant-based corn fiber media grown by American farmers, replacing traditional petroleum-based filter materials, so you get cleaner air with a smaller environmental footprint.

Can I subscribe and save?

Yes. Choose Subscribe & Save at checkout to set your own delivery frequency, get free shipping on every order, and pause, swap, or cancel anytime from your account.

Not sure this filter fits your system?

Message our team before or after you order and we'll help you confirm the right size for your HVAC system or return.
