Nordic Pure 20x24x1 Pure Carbon Pleated Odor Reduction Filters - 6

In this review the Nordic Pure 20x24x1 Pure Carbon Pleated Odor Reduction furnace filters are examined for homeowners and small offices wanting cleaner, less odorous indoor air. The bottom line: these filters are best for people who want reliable odor control plus particle capture without messy loose carbon, because the pleated, carbon-infused media provides significantly more odor-absorbing surface than a flat panel while maintaining airflow. The review highlights build quality, actual sizing, and how they perform as either standalone filters or pre-filters in higher-efficiency systems.

Key Features

• Pleated carbon media: The pleated design offers three times the carbon media versus a flat panel, increasing contact time with airflow for better odor reduction.
• Carbon-infused media: Naturally derived charcoal is infused into the non-woven polyester so there are no loose carbon particles to make a mess in the filter housing.
• Durable frame: A heavy duty, moisture-resistant beverage board frame gives the filter steady support and helps resist damage during handling and installation.
• Support grid: A bonded metal mesh grid supports the pleats, helping the media hold shape and maintain consistent airflow through the filter life.
• Anti-microbial media: The filter media will not support mold or bacteria growth, which helps preserve indoor air quality in damp conditions.
• Made in the USA: Domestic manufacturing offers consistent build quality and traceability for buyers who prefer US-made products.

Who It's For

These filters suit homeowners and small-office managers who want both particulate capture and odor/VOC reduction from a single, simple filter. They are particularly useful in spaces with cooking, pet, or mild chemical odors where activated carbon can make a noticeable difference and where maintaining airflow is still important.

People who need a very high MERV rating for severe allergy or medical-grade filtration should look elsewhere or use these as a pre-filter ahead of a higher-efficiency secondary filter. Also measure carefully: some buyers reported confusion about nominal versus actual size, so double-check the actual dimensions before buying.

Pros & Cons

Pros

• Good odor reduction from increased carbon content in the pleated media.
• Clean handling thanks to carbon-infused media that avoids loose particles.
• Sturdy construction with moisture-resistant frame and metal mesh support grid.
• Manufactured in the USA, reflecting consistent build quality.

Cons

• Actual dimensions are slightly smaller than the nominal size, which has caused fit questions for some buyers.
• MERV rating and filtration efficiency are discussed inconsistently by customers, so those needing a specific MERV level should verify suitability.

Frequently Asked Questions

Will these filters control pet and cooking odors?
Yes, the activated charcoal-infused pleated media is designed to absorb odors and VOCs commonly associated with pets and cooking.

Are there loose carbon particles in the box?
No, the carbon is infused into the non-woven media so customers should not find messy loose carbon in the filter or housing.

Do these replace high-MERV filters?
They are suitable for odor control and general particle capture but those needing very high MERV filtration should use these as pre-filters or choose a filter with a specified higher MERV rating.
