Filtrete 20x25x1 Furnace AC Air Filter, 4-Pack MPR 700 (MERV 8) — 1" Pleated Electrostatic, 3-Month Life

Filtrete 20x25x1 MPR 700 is a 1-inch pleated, electrostatically charged HVAC filter that captures lint, pollen, dust and pet dander while maintaining healthy airflow for up to 90 days per filter.

If you want a reliable, no-fuss replacement filter for your furnace or air conditioner that balances particle capture with system airflow, this Filtrete 4-pack is built for routine home use. Each pleated filter uses an electrostatic charge to attract and hold particles that ordinary non-electrostatic or washable filters can miss. The pack gives you a three-month service interval per filter under typical household conditions, plus compatibility with Filtrete's Smart App for replacement reminders.

How does this filter improve everyday indoor air quality?

The electrostatically charged media draws in and traps airborne particles as air cycles through your HVAC system. It’s designed to remove common household contaminants without significantly restricting airflow, which helps maintain heating and cooling efficiency.

• Electrostatic pleated media for enhanced particle attraction.
• MPR 700 (equivalent to MERV 8) for capturing pollen, pet dander and dust.
• Pleated design increases surface area compared to flat filters.
• Recommended 90-day replacement to sustain performance.

Will it fit my system and affect HVAC performance?

The listed actual size is 19.880 x 25.563 x 0.8125 inches; confirm your unit accepts a 20x25x1 filter before ordering. Because the filter is a 1-inch pleated design with balanced resistance, it’s suitable for most residential furnaces, air handlers and window AC units that specify a 1-inch filter.

• Check your system’s filter slot for the 20x25x1 dimension.
• 1-inch nominal thickness is compatible with common residential HVAC systems.
• Designed to maintain adequate airflow while trapping particles.

How often should I replace the filter and how can I remember?

Filtrete recommends replacing these 1-inch pleated filters every 90 days under normal household conditions. If you have pets, allergy sufferers, or higher indoor pollution, consider checking and replacing filters more frequently.

• Factory-specified 3-month replacement interval for typical use.
• Shorten replacement cycles for pets, renovation dust, or high pollen seasons.
• Scan the barcode in the Filtrete Smart App to set 30/60/90-day reminders and get notifications.

What makes Filtrete different from basic fiberglass or washable filters?

Unlike flat fiberglass or washable filters, Filtrete’s pleated, electrostatically charged media provides more capture surface and an active attraction mechanism for small particles. This results in better particle retention while still allowing sufficient airflow for routine HVAC operation.

• Pleated construction increases filtering area versus fiberglass panels.
• Electrostatic charge helps trap smaller particles that slip past non-electrostatic media.
• Rated by MPR and MERV systems (MPR 700 corresponds to MERV 8) for performance clarity.

Who is this for: Homeowners and renters looking for an affordable, regularly scheduled air filter that improves capture of everyday particles without overburdening HVAC systems. It’s a practical choice for households with seasonal allergies, pets, or anyone wanting a straightforward upgrade from basic flat or washable filters. If you need higher-efficiency filtration for specialized health or industrial needs, consider higher MPR/MERV options appropriate for your system and professional guidance.
