Filtrete 16x25x1 AC Furnace Air Filter, MERV 11, MPR 1000, Micro Allergen Defense, 3-Month Pleated 1-Inch Electrostatic Air Cleaning Filter, 4 Pack (Actual Size 15.69 x 24.69 x 0.81 in)
Overview
This Filtrete 16x25x1 MERV 11 furnace/AC filter (MPR 1000) is a pleated, electrostatic 1-inch HVAC filter sold as a 4-pack for routine home use. It’s engineered to trap a broad range of particles — from large dust and pollen to smaller pet dander, smoke and some smog — using Filtrete’s Micro Allergen Defense media. Each filter’s actual dimensions are 15.69 x 24.69 x 0.81 inches, so measure your slot before buying. Designed for three-month replacement cycles, the 4-pack gives roughly a year of coverage for a single system when changed quarterly. This product is a practical upgrade for homeowners and renters seeking improved indoor air quality without swapping to thicker filters or standalone purifiers.

Pros & Cons
Pros
- MERV 11 / MPR 1000 rating captures a wide range of particles including pet dander, smoke, pollen and household dust.
- Electrostatic pleated media increases particle capture efficiency without excessively restricting airflow.
- 4-pack provides value and convenience—about 12 months of quarterly replacements for one system.
- Slim 1-inch profile fits most standard residential filter slots and is easy to install.
- Made by 3M/Filtrete, a reputable brand with consistent manufacturing quality.
Cons
- 1-inch thickness gives less dust-holding capacity than 2- or 4-inch filters, so it can clog faster in dusty or pet-heavy homes.
- Not a true HEPA filter; may not be sufficient alone for households with severe asthma or allergy sufferers needing higher-grade filtration.
- Actual dimensions (15.69 x 24.69 x 0.81 in) are slightly under nominal size—some tight slots may need careful measurement.
- Higher filtration (MERV 11) can modestly increase blower load on older HVAC systems; check compatibility if system is aged.
Recommendations
- Homeowners with pets who want to reduce pet dander and hair throughout living spaces.
- Families who live in areas with seasonal pollen or light smoke and want improved whole-house filtration.
- Renters or homeowners who prefer low-maintenance disposable filters replaced every 90 days.
- Anyone upgrading from a basic fiberglass or MERV 6–8 filter seeking better filtration without switching to thicker filters.
