Filtrete 11.68 x 23.68 x 0.81 in Air Filter – MERV 11, MPR 1000, Allergens & Pet Dander, 4-Pack

Cleaner, fresher air for your home with Filtrete

The Filtrete 11.68 x 23.68 x 0.81 in air filter combines a proven electrostatic design with a 3‑in‑1 filtration approach. Engineered to pull in and trap a wide range of particles, it supports a healthier-feeling living space while helping your HVAC system breathe easier through cleaner air and steadier airflow.

With a 1000 Microparticle Performance Rating (MPR) and a MERV 11 rating, this filter targets both visible dust and the tiny irritants that often go unnoticed. The result is air that can feel crisper as you go about daily activities—from cooking to lounging to playtime with pets.

What this Filtrete filter captures

• Household dust and lint
• Pollen and mold spores
• Dust‑mite debris and pet dander
• Smoke, smog, and bacteria particulates

Key benefits you may notice in daily life

• Improved indoor air quality with each pass through the filter
• Smoother, more consistent airflow through your HVAC system
• Reduced buildup of dirt in ducts and on components, potentially supporting system efficiency
• Easy maintenance with a 3‑month replacement cadence (adjust to your environment)

Designed by 3M engineers, the Filtrete media is electrostatically charged to attract particles like tiny magnets. While performance varies with home conditions, many households notice a more comfortable breathing environment and less frequent surface dust accumulation between replacements.

Practical use and setup

This 4‑pack is suitable for furnaces, air conditioners, or any standard HVAC system needing a 1‑inch pleated filter. For added convenience, compatible Filtrete apps can help you set replacement reminders and track filter life, turning maintenance into a simple routine.
