16x28x6 MERV 11 Air Filter (2-Pack) - Superior Pet & Allergy Defense

Our review of this 16x28x6 air filter (actual size 15.50 in x 26.88 in x 6.00 in) finds it best suited for homeowners and small businesses looking for a balance of particle capture and airflow. The single biggest reason to buy is its MERV 11 performance, which captures a high proportion of fine dust, pet dander, and common allergens without noticeably restricting HVAC airflow. Installation is straightforward and the construction aims to last longer than disposable fiberglass alternatives.

Key Features

• Whole house replacement: Sized for furnaces, air conditioners, and heat pumps to maintain system efficiency across a home or business.
• MERV 11 filtration: Synthetic media captures up to 95% of dust and common allergens while remaining compatible with typical residential HVAC flow needs.
• Longer lasting media: Electrostatically charged pleated media with 8 pleats per ft traps smaller particles and is designed to last about three times longer than fiberglass filters.
• Durable frame: Recyclable beverage board frames with dual wire backing resist temperature extremes and improve handling vs basic cardboard frames.
• Made in the USA media: The filter media is manufactured domestically and intended for 90 day replacement intervals for best performance.
• Model compatibility: Sized and compatible with Aprilaire Space-Gard 401 and Cleaner Model 2400, plus several Lennox replacements.

Who It's For

This filter is a practical choice for households with pets, allergy sufferers, or anyone wanting improved indoor air quality without upgrading to a high-resistance filter. It suits owners of furnaces, AC units, or heat pumps that accept a 16x28x6 nominal filter and who prefer a 90 day replacement cycle.

It is less appropriate for systems that require an exact factory-recommended non-standard size or for users needing true HEPA-level filtration; those customers should choose a dedicated high-efficiency purifier or check their system compatibility before buying.

• Captures fine dust and pet dander effectively while maintaining good airflow.
• Sturdy beverage board frame with dual wire backing improves durability over plain cardboard designs.
