Filtrete 18x18x1 Air Filter | MPR 700, MERV 8 | 2-Pack (Actual 17.81 x 17.81 x 0.81 in)

Cleaner air starts with smarter filtration

In homes that run a tight ship from floor to ceiling, a dependable air filter can make a noticeable difference in how air moves through your heating and cooling system. The Filtrete 18x18x1 filter set uses an electrostatic charge to attract and trap multiple particle types as air passes through the pleated media. Rather than relying on a single layer, this design targets many common indoor irritants while maintaining steady airflow—so your HVAC can work efficiently without added effort from you. While results will vary by space, you may experience less dust circulation and a smoother overall air experience in rooms you use most.

Key technology and filtration levels

• Electrostatic filtration attracts and captures lint, pollen, dust and pet dander as air flows through the filter.
• 3-in-1 Filtrete technology balances particle trapping with clean air movement, designed to work within your HVAC system.
• MPR 700 / MERV 8 rating signals a solid level of filtration for everyday particles while preserving airflow.
• 2-pack gives you ample coverage for ongoing replacement every 90 days per filter, simplifying maintenance.

What you get and how it’s built for your home

• Two pleated filters with an actual size of 17.81 x 17.81 x 0.81 inches, fitting many 18x18x1 slots.
• Designed for standard 1-inch HVAC filters, compatible with furnaces and air conditioners that use 18x18x1 frames.
• Electronic or app-enabled maintenance features help you manage replacement timing without guesswork.

Real‑world use cases and everyday benefits

Whether you’re dealing with seasonal pollen, pet dander, or everyday dust, these filters are built to perform without compromising airflow. In busy homes with pets or in apartments near high-traffic streets, you may notice a cleaner feel in common living areas as particles are intercepted before they circulate. The 2-pack approach keeps you prepared and minimizes the chance of running a filter with expired performance.

Tips to maximize filtration

• Change your filter at least every 90 days for optimal performance on 1-inch filters.
• Use the Filtrete Smart App to scan the barcode on the packaging and set a replacement countdown for 30, 60, or 90 days.
• Pair with regular HVAC system maintenance to support consistent airflow and system efficiency.

Note that while filtration can influence the air you move through your space, it does not cure illnesses or replace professional medical advice. This Filtrete filter aims to reduce the intake of common indoor particles, supporting a practical approach to maintaining indoor air quality through your existing HVAC system.
