Most types of filters are built to be tossed. You use them for a few months, throw them away, and repeat. The Filtrete™ Refillable Air Filter changes that model and makes it easier for homeowners to save money on refills.

Instead of throwing out the entire thing, you keep the reusable air filter frame and just change out the collapsible filter insert. When they told us about this product, Filtrete highlighted that this one change reduces waste by 20% and lets you reuse 70% of the product. GOOD, RIGHT?

It may seem like a small shift, but over time, it makes a big difference for your wallet... and the environment.

Reusable Frame. Lower Cost. Less Waste.

Traditional filters are one-and-done. That adds up—more waste, more money, more hassle. This system does it differently. The reusable frame is built to last up to 20 years. You only replace the filter insert when needed, and each refill takes up 75% less space than a typical air filter. The refills also cost less than comparable traditional filters.

Less waste means fewer filters in landfills. Less bulk means easier storage. And over time, reusing the frame means serious savings. The packaging is 100% curbside recyclable too, so you're not adding extra trash there either.

Still Delivers Clean, Quality Air

This isn’t just about cutting waste; it’s still a high-performing filter. The reusable filter captures 42% more microparticles than the MERV 12 minimum. It's CERTIFIED Asthma & Allergy Friendly®, which means it was tested by a third party and shown to remove:

  • Over 95% of pollen
  • 92.5% of dust mite allergens
  • 85% of cat allergens
  • 50% of fine microparticles like smoke and smog

It comes in two filtration levels: MPR 1550 and MPR 1000, so you can choose what works best for your home. And each refill lasts up to 12 months. That’s fewer filter changes per year, with the option to get smart alerts through the Filtrete app.

Makes Sense for Long-Term Living

This isn't just a refillable filter—it’s a longer-term solution. Filtrete expects that the frame itself should last as long as your HVAC system. That’s up to two decades of reusing, not rebuying.

Here’s what makes it work:

  • Frame is built to last up to 20 years
  • Refills are collapsible, taking up 75% less storage space
  • Reduces disposable waste by 20% compared to traditional filters
  • Saves money over time with lower-cost refills
  • Curbside recyclable packaging
  • Available in common sizes (16x25x4 and 20x25x4)

The $90 starter kit comes with the reusable frame and two MPR 1550 refill filters to get you going. Refills are available for $45-60, depending on the product. It’s available now at Amazon, Walmart, and Lowe’s.
