Nordic Pure 20x20x1 MERV 12 Plus Carbon Furnace Filters - Odor Control

In this review of the Nordic Pure 20x20x1 MERV 12 Plus Carbon furnace filters, the bottom line is simple: these are best for households that need both higher filtration and odor control without spending on premium branded replacements. The reviewer found the dual material construction - a MERV rated pleated layer fused to an activated carbon layer - to be the defining feature because it traps dust and captures odorous gases while keeping acceptable airflow. Measure your filter slot and compare to the actual size to ensure the best fit before buying.

Key Features

• Actual size clarity: The box lists the actual filter dimension as 19 1/2 x 19 1/2 x 3/4 in so buyers can verify fit against their furnace slot before installing.
• MERV 12 filtration: The MERV 12 media captures a wide range of airborne dust and particulate matter, offering filtration roughly equivalent to MPR 1500-1900 for improved indoor air quality.
• Activated carbon layer: A bonded carbon layer helps attract and hold odorous gases and VOCs, which is useful in kitchens, pet households, or spaces with mild smells.
• Durable construction: Filters use a moisture-resistant beverage board frame and metal mesh support so pleats stay supported and the unit holds shape during use.
• Electrostatic media: Permanently charged material helps particles cling to the media, improving dust capture without significantly restricting airflow.

Who It's For

This filter is aimed at homeowners and renters who need better than basic filtration and want some level of odor control without buying separate deodorizing products. It suits people with pets, light household odors, or those sensitive to dust who want the step up to MERV 12 performance.

Those who should look elsewhere include households requiring medical-grade filtration or highly restrictive HVAC systems where even small differences in thickness matter; also check exact dimensions carefully because some customers reported fit variations compared to other brands.

Pros & Cons

Pros

• Higher filtration level removes a broad range of dust and particulate matter for cleaner air.
• Carbon layer reduces common household odors and traps VOCs effectively in typical home use.
• Sturdy frame and metal mesh support provide reliable durability and maintain pleat shape.
• Cost effective alternative to more expensive branded replacement filters.

Cons

• Actual dimensions are 19 1/2 x 19 1/2 x 3/4 in, and a few buyers reported fit differences versus other brands, so measuring before purchase is important.
• Some users had mixed impressions of airflow, with a minority noting reduced flow depending on their HVAC setup.

Frequently Asked Questions

Will this filter reduce pet odors?
Yes, the activated carbon layer helps trap common household odors and some VOCs, making it helpful for homes with pets.

Is this the same as a 20 x 20 x 1 in filter?
The nominal size is 20 x 20 x 1 in but the actual dimensions are 19 1/2 x 19 1/2 x 3/4 in, so measure your slot and compare to the actual size.

Does the MERV 12 rating affect airflow?
MERV 12 captures more particles than lower-rated filters; most systems handle it fine, but a few users reported mixed airflow impressions so verify compatibility with your HVAC before extended use.
