Filtrete 20x30x1 Air Filter 4-Pack — MPR 700 (MERV 8), Pleated Electrostatic for HVAC

Filtrete 20x30x1 MPR 700 air filters (4-pack) are pleated, electrostatically charged HVAC filters designed to attract and trap common household particles like dust, pollen and pet dander while maintaining airflow for heating and cooling systems.

These Filtrete filters use the brand’s 3-in-1 technology and an electrostatic charge to collect more airborne particles than standard non-electrostatic pleated or washable screens. Each 1-inch filter is rated MPR 700 (equivalent to MERV 8) and comes as a convenient four-pack for quarterly replacement, helping you keep indoor air cleaner with routine changes.

What makes Filtrete MPR 700 different from basic fiberglass or washable filters?

The Filtrete MPR 700 uses an electrostatic charge and pleated media to increase particle capture without severely restricting airflow. Compared to flat fiberglass and washable options, the pleated, charged design captures more and smaller particles while preserving HVAC performance.

• Electrostatically charged media attracts particles rather than relying only on mechanical interception.
• Pleated construction expands surface area for longer life and better capture.
• MPR 700 / MERV 8 rating targets common household particles like pollen and pet dander.

How often should I change these 1-inch HVAC filters and how does the Filtrete app help?

For 1-inch filters, Filtrete recommends replacing them at least every 90 days; homes with pets or higher dust loads may need changes every 30–60 days. The Filtrete Smart App simplifies reminders: scan the barcode, pick 30/60/90 days, and receive a notification when it’s time to swap filters.

• Standard replacement interval: 90 days for typical households.
• Shorten to 30–60 days if you have pets, allergies, or heavy dust.
• Use the app barcode scan to set automatic replacement alerts.

Will these filters affect my HVAC system’s airflow or efficiency?

Filtrete pleated MPR 700 filters are engineered to balance filtration and airflow so your furnace or AC can run efficiently. Their pleated design increases media area, which helps maintain airflow while capturing more particles than thin fiberglass pads.

• Pleated media increases filter surface area to reduce pressure drop.
• Designed for typical residential HVAC systems that accept 1-inch filters.
• Changing filters regularly helps preserve system efficiency and longevity.

What types of particles will these filters capture?

These filters target common indoor particles including lint, dust, pollen and pet dander, improving overall household air cleanliness. The MPR 700 rating corresponds to strong performance on larger and many mid-sized particles without being a high-restriction high-MERV unit.

• Captures lint, dust, pollen and pet dander effectively.
• MPR 700 rating provides reliable performance for everyday indoor particles.
• Not a replacement for specialized medical-grade filters where required.

Who is this for? The Filtrete 20x30x1 MPR 700 4-pack is aimed at homeowners and renters who want a practical, quarterly-maintenance filtration upgrade over disposable fiberglass or washable filters. It suits households with pets, seasonal pollen concerns, or anyone seeking a balance between improved particle capture and continued HVAC performance—plus convenient app-based replacement reminders for busy schedules.
