Filtrete 16x20x1 AC Furnace Air Filter MERV 12 - Allergy Relief

In this review the Filtrete 16x20x1 AC Furnace Air Filter (2-pack) is evaluated for homes seeking better indoor air quality and allergy relief. The bottom line: this MERV 12, MPR 1500 pleated filter is best for households with pets, allergy sufferers, or anyone wanting finer particle capture than standard fiberglass filters. It consistently traps microscopic particles like pollen, pet dander and some bacteria and virus-carrying particles while remaining easy to install and maintain in typical HVAC systems.

Key Features

• MERV 12 / MPR 1500: Provides higher efficiency capture of microparticles such as pollen, pet dander and smoke compared with lower-rated filters.
• 3-in-1 Filtrete technology: Designed to attract and capture both large and small particles without severely restricting airflow in most residential systems.
• Certified asthma & allergy friendly: Independently certified to help reduce common triggers for asthma and allergy sufferers in the home.
• 3-month pleated design: The 1-in pleated filter is intended for replacement about every 90 days under normal conditions to maintain optimal HVAC performance.
• Enabled with Dash Replenishment: Optional sensor reordering can automatically place replacement orders when filters reach end of life, reducing the risk of running a dirty filter.
• Outperforms fiberglass: Captures significantly more small particles than basic fiberglass filters, improving perceived air cleanliness and reducing dust buildup.

Who It's For

This filter is best for families and individuals who want a clear improvement in indoor air quality and who deal with allergens, pet dander or smoke. People with ventilation systems that accept 1-in filters and who are willing to replace filters every three months will benefit most.

It is not the best choice for systems that require thicker 4-in or 5-in filters for longer service intervals, or for those who cannot accommodate slightly larger actual size differences; some users report fit issues on odd-sized or nonstandard inlets, so double-check your opening before purchase.
