Filtrete 20x20x1 Furnace/AC Air Filter MERV 8 (MPR 700) 4-Pack — 1" Pleated Electrostatic, 90-Day

Filtrete 20x20x1 MERV 8 (MPR 700) is a pleated electrostatic air filter designed to capture lint, pollen, dust, and pet dander while maintaining good airflow for 90-day service intervals.

If you want a reliable furnace or AC filter that balances particle capture with HVAC performance, this Filtrete 4-pack offers an electrostatically charged 1-inch pleated design rated MPR 700 (equivalent to MERV 8). It’s engineered to attract and trap common household particles more effectively than non-electrostatic or washable fiberglass filters, and it’s sized to fit standard 20 x 20 x 1 filter slots (actual size 19.880 x 19.880 x 0.78 in). The package contains four filters meant for roughly 90 days of use per filter under typical residential conditions.

How does this filter improve indoor air without restricting airflow?

The Filtrete 3-in-1 technology combines pleated media and an electrostatic charge, which pulls particles from the airstream while preserving low resistance to airflow. That helps your furnace or air conditioner run efficiently and keeps ventilation effective. It outperforms basic fiberglass and washable designs at capturing small to medium particles without creating excessive pressure drop.

• Electrostatic pleated media attracts and holds particles.
• MERV 8 (MPR 700) balance of capture vs airflow for residential HVAC.
• Designed for typical 90-day replacement to maintain system efficiency.

What types of particles will the MPR 700 filter capture in my home?

MPR 700 targets common airborne irritants found around homes, reducing the concentration of lint, pollen, dust, and pet dander as air cycles through your system. While not a hospital-grade filter, it meaningfully reduces these everyday particles and helps keep vents, coils, and ducts cleaner. It’s a practical step toward fresher indoor air when combined with regular cleaning and ventilation.

• Effective on pollen and pet dander that aggravate allergies.
• Captures household dust, lint, and larger airborne particulates.
• Helps reduce buildup on HVAC components, supporting performance.

How often should I change the filter and how do I track replacements?

For a 1-inch Filtrete filter, change every 90 days under normal household conditions; households with pets, smokers, or higher dust loads may need to change it every 30–60 days. Filtrete supports replacement tracking via the Filtrete Smart App: scan the barcode, choose a 30/60/90-day cycle, and receive a notification when it’s time to swap filters. Regular replacement preserves capture efficiency and keeps your system running smoothly.

• Standard recommendation: replace every 90 days for 1-inch filters.
• Use the Filtrete Smart App barcode scan to set reminders.
• Increase frequency for pets, allergies, or heavy particulate loads.

Will this filter fit my HVAC system and will it affect performance?

The filters are labeled for nominal 20x20x1 filter slots; actual dimensions are 19.880 x 19.880 x 0.78 inches, so verify your return grille or filter cabinet accepts these actual measurements. Because it’s designed for low resistance airflow at MERV 8, most residential furnaces and air conditioners will operate without added strain. Always confirm your system’s filter size and manufacturer guidance before installing.

• Actual dimensions: 19.880 x 19.880 x 0.78 in — check your slot clearance.
• MERV 8 (MPR 700) suitable for most residential HVAC setups.
• Four filters in the pack for multiple change cycles or multiple units.

Who is this for: This Filtrete 4-pack is a good fit for homeowners and renters who want better-than-basic filtration for everyday household particles without the airflow penalties of higher-MERV industrial filters. It’s especially useful for homes with pets, seasonal pollen, or routine dust where balanced performance, easy app-based replacement reminders, and trusted brand reliability are priorities.
