Cleaner air, everyday comfort

Filtrete 20x23x1 MERV 11 MPR 1000 filters are designed to help refresh the air in your home. This 4-pack of 1-inch pleated filters fits most standard furnaces, air conditioners, and HVAC systems, with an actual size of 19.68 x 22.68 x 0.81 inches. By combining strong filtration with steady airflow, these filters aim to contribute to a fresher, more comfortable living space between replacements.

What makes Filtrete different

Built with Filtrete 3-in-1 technology, this filter pulls in and traps a broad range of particles while allowing cleaner air to pass through. The combination of MPR 1000 and MERV 11 means the filter can handle a wide spectrum of contaminants from everyday dust to smaller irritants found in household air.

  • Exclusively designed Filtrete 3-in-1 technology to capture particles while preserving airflow
  • High filtration rating (MPR 1000, MERV 11) targeting microparticles as small as 0.3 microns up to larger debris
  • Captures common household particulates such as dust, pollen, and pet dander
  • Asthma and allergy-friendly certification signals a focus on cleaner indoor air

Maintenance you can manage

For consistent performance, change the filter every 90 days. A 4-pack helps keep a ready supply on hand, reducing the guesswork when it’s time for maintenance. The Filtrete Smart App lets you scan the packaging barcode and set 30-, 60-, or 90-day reminders so you’re alerted when it’s time to replace.

  • 90-day replacement is recommended to maintain airflow and filtration efficiency
  • Smart App reminders help you track filter life without manual logs
  • 4-pack provides ongoing value and convenience for multiple units or seasonal use
  • Suitable for furnaces, air conditioners, and whole-HVAC systems

Where you’ll notice the difference

Designed for everyday homes, these filters work across seasons and settings, keeping airflow steady while filtering a broad range of particles. The actual size fits typical filter housings, making replacement straightforward.
