Nordic Pure 20x25x1 MERV 14 Plus Carbon Pleated Air Filters 6 Pack

Our review of the Nordic Pure 20x25x1 MERV 14 Plus Carbon filters finds them best for homeowners who want high-efficiency particulate removal plus basic odor control. The biggest reason to buy is the combination of a MERV 14 filtration performance with an activated carbon panel, which captures fine dust, allergens and many household odors while keeping acceptable airflow for most residential systems. Measure your existing filter slot and compare to the listed actual size before ordering.

Key Features

• Actual and nominal size: The filters list a nominal 20 x 25 x 1 but the actual dimensions are 19 1/2 x 24 1/2 x 3/4 in, so measuring the filter slot ensures proper fit.
• MERV 14 performance: High-efficiency media captures a wide range of airborne particulates to improve indoor air quality and reduce dust levels.
• Activated carbon panel: A flat panel infused with activated charcoal helps attract and hold odorous gases and volatile organic compounds for fresher air.
• Electrostatically charged media: Permanently charged synthetic fibers act like a magnet to help dust cling to the filter, improving capture without excessive airflow restriction.
• Anti-microbial media: Filter media is treated to resist bacteria and mold growth, supporting a healthier environment.
• Made in the USA: Manufactured domestically, which may be important to shoppers prioritizing local production.

Who It's For

This filter is aimed at homeowners and renters with forced-air HVAC systems who need stronger particulate removal than typical basic pleated filters, and who also want some level of odor control from released gases and household smells. It suits users concerned about allergens, pet dander, and smoke or cooking odors who are able to check fit by measuring their filter compartment.

People who should look elsewhere include systems that require an exact 1 in thickness for a snug seal or those with very restricted blower capacity; because the actual thickness is 3/4 in, some users reported a slightly smaller fit. Also, if you need industrial gas removal rather than residential odor reduction, a specialized carbon treatment would be preferable.

Pros & Cons

Pros

• High-efficiency MERV 14 media captures fine dust and many allergens.
• Added activated carbon helps reduce common household odors and VOCs.
• Permanently electrostatically charged material improves particle capture without excessive pressure drop.
• Anti-microbial treatment reduces risk of bacterial or mold growth on the media.

Cons

• Actual size is 19 1/2 x 24 1/2 x 3/4 in, and a few customers found the fit slightly smaller than expected.
• Carbon panel provides moderate odor control but is not a substitute for heavy chemical or industrial gas filtration.

Frequently Asked Questions

Will this filter fit my 1 in slot?
Check your filter compartment and measure the opening; the listed nominal size is 20 x 25 x 1 in but the actual filter measures 19 1/2 x 24 1/2 x 3/4 in.

Does the carbon remove strong chemical odors?
The activated carbon panel helps with common household odors and some VOCs, but it is not designed for heavy industrial chemical removal.

How often should I change these filters?
Replacement frequency depends on use and environment; for best performance check every 1-3 months and replace sooner in high dust or pet environments.
