Filtrete 23.5x23.5x1 AC Furnace Air Filter – MERV 11, MPR 1000, Micro Allergen Defense, 3-Month Pleated Filter, 6 Pack (Actual Size 23.188x23.188x0.81 in)

Cleaner indoor air starts with Filtrete Micro Allergen Defense

The Filtrete 1000 MPR Micro allergen reduction filter is designed to help your home feel fresher with every pass. Its electrostatic fibers act like tiny magnets, drawing in a wide range of airborne particles and keeping them from circulating back into living spaces. This 1 inch pleated filter is built to work with your furnace, air conditioner, or HVAC system while you enjoy a consistently clear airflow.

How it works

The filter combines positively and negatively charged fibers to attract both large and fine particles. This electrostatic action helps capture smaller particles that non electrostatic filters may miss, contributing to a cleaner in-home environment over time.

• Electrostatic design attracts and captures dust, pollen, pet dander, smoke, and more
• 1000 MPR and MERV 11 rating target a broad range of particles
• Designed to outperform many non electrostatic fiberglass and washable options

Indoor air quality can be two to five times more polluted than outdoor air in some homes. With each pass, this filter aims to reduce the concentration of common irritants, helping you maintain a healthier-feeling living space.

What it captures

Filtrete targets a broad spectrum of particles including household dust, pollen, dust mite debris, mold spores, pet dander, smoke, smog, and bacteria. The 3-in-1 Filtrete technology is designed to pull in both large and tiny particles so cleaner air can flow through your system.

• Large particles such as lint and dust are captured
• Smaller allergens like pollen and dander are reduced
• Air passed through the filter can feel cleaner and fresher

Maintaining HVAC efficiency is a practical benefit. A clean filter helps your system breathe more easily, potentially reducing strain on motors and maintaining steady airflow. For this 1 inch filter, replacement every 90 days is recommended, though conditions at home can vary.

Real world use and convenience

Perfect for homes with pets, during high pollen seasons, or in urban settings, this six pack provides ongoing replacements for busy households. The package supports a straightforward swap in standard units, keeping maintenance manageable over time. A handy feature is the Filtrete Smart app, which can remind you when it is time to replace by scanning the barcode on the packaging and setting a countdown.

Designed to fit your system

Nominally sized at 23.5x23.5x1 inches, the filter set you receive is built for typical residential HVAC setups. In practice, the actual size is 23.188x23.188x0.81 inches, ensuring compatibility with many standard houshold units while maintaining a snug fit.
