20x22x1 MERV 10 Air Filter Replacement (4-Pack) - Low Resistance

Our review of the 20x22x1 MERV 10 air filter (4-pack) finds it a practical upgrade for homeowners who want noticeably cleaner indoor air without sacrificing airflow. The single biggest reason to buy is its balanced performance: an electrostatically charged pleated media that captures microscopic particles like pollen, mold and smoke while maintaining industry leading low air flow resistance, so HVAC systems keep running efficiently. It is made in the USA with a recycled one-piece frame that reduces waste, which will matter to buyers who prefer domestic and more sustainable options.

Key Features

• MERV 10 filtration: Captures up to 85% of airborne particles including pollen, pet dander, mold spores and smoke for cleaner indoor air.
• Electrostatic pleated media: Uses electrostatically charged fibers to improve microscopic particle capture without greatly increasing resistance to airflow.
• Low air flow resistance: Designed to maintain HVAC efficiency so furnaces and air conditioners do not work harder than necessary.
• Made in USA: Manufactured by BNX Converting in Houston, TX, assuring domestic production and consistent quality control.
• Sustainable frame: One-piece recycled cardboard frame reduces environmental waste compared with multi-piece frames.
• Compatible sizing: Labeled 20x22x1 with an actual size of 19 11/16 x 21 11/16 x 3/4 to fit common HVAC filter slots.

Who It's For

This filter is a good fit for homeowners and renters looking for an affordable way to reduce common indoor allergens and particulates without upgrading to high-resistance, high-MERV filters that can impede system performance. It is especially useful for people who want a balance of particle capture and maintained airflow, and those who prefer products made in the USA and packaged with sustainability in mind.

Those who need hospital-grade filtration, extremely fine particle capture beyond MERV 10, or specialized chemical gas adsorption should look elsewhere. Likewise, systems that specify thicker or unusually sized filters will require different parts; check the actual dimensions of 19 11/16 x 21 11/16 x 3/4 before purchase.

Pros & Cons

Pros

Frequently Asked Questions

Will this filter fit my 20x22x1 slot?
Yes; the nominal size is 20x22x1 and the actual size is 19 11/16 x 21 11/16 x 3/4 in, which fits standard 20x22x1 filter housings.

How well does it capture fine particles?
With a MERV 10 rating and electrostatically charged media, it captures a large portion of pollen, dust mites, pet dander, mold spores and smoke but is not a substitute for higher MERV medical-grade filtration.

Is this product sustainably made?
Yes; it uses a one-piece recycled cardboard frame to reduce waste and is manufactured in an EPA-registered facility in Houston, TX.
