Nordic Pure 20x24x1 Pure Carbon Pleated Odor Reduction Filters - 3

In this review the Nordic Pure 20x24x1 Pure Carbon Pleated Odor Reduction Furnace Air Filters 3 Pack is examined for homeowners and small offices who need odor control without sacrificing airflow. The single biggest reason to consider these filters is their pleated, carbon-infused media that provides more active charcoal per filter than a flat panel design, which helps reduce common indoor odors and VOCs while still fitting many standard furnace systems. The review looks at build, fit, and everyday performance over several replacement cycles.

Key Features

• Pleated carbon media: The pleated design contains three times the carbon media versus a flat panel, increasing odor adsorption while maintaining airflow.
• Actual and nominal sizing: Labeled as a 20 x 24 x 1 nominal size, the filters measure 19 1/2 x 23 7/16 x 3/4 in actual size to fit common housings that accept slightly undersized panels.
• Carbon infused media: Carbon is bonded into the media so there are no messy loose carbon particles to shed into the ductwork or home environment.
• Durable frame and support: A heavy duty, moisture resistant beverage board frame with a bonded metal mesh grid keeps pleats supported and resists sagging in humid conditions.
• Mold and bacteria resistance: The non-woven polyester base media does not support mold or bacterial growth, helping maintain healthier indoor air during use.
• Made in the USA: Manufactured domestically, which can be important for buyers prioritizing local production and consistent quality control.

Who It's For

This filter pack is a good fit for homeowners, renters, or small office managers who want a straightforward replacement filter that reduces odors from cooking, pets, and everyday VOCs while also capturing airborne particles. It is particularly suited to systems where a single-stage filter is used or where a pre-filter is desirable before a high-efficiency secondary filter.

Users who require a precise high MERV rating or those using custom or exact tight-tolerance filter racks should double-check sizing and performance needs; customers expecting a higher MERV grade or exact full-size dimensions may want to compare specifications or consider alternate high-efficiency options.

Pros & Cons

Frequently Asked Questions

Will these filters remove household odors?
Yes, the activated carbon infused in the pleated media is designed to absorb common household odors and VOCs more effectively than a flat panel carbon filter.

Do these filters fit exactly in a 20 x 24 x 1 slot?
The filters are nominally 20 x 24 x 1, but the actual dimensions are 19 1/2 x 23 7/16 x 3/4 in, so check the filter slot clearance before purchase.

Are there loose carbon particles?
No, the carbon is infused into the media to prevent messy loose carbon from shedding into the air system.
