Nordic Pure 20x24x4 Pleated Air Filter MERV 14 Plus Carbon - Odor

Our review of the Nordic Pure 20x24x4 Pleated Air Filter MERV 14 plus carbon finds it best suited for homeowners who want high-efficiency particle capture with an added layer of odor control. The bottom line: this replacement filter provides high MERV 14 filtration comparable to MPR 2800 while the activated carbon panel helps reduce common household odors and VOCs. It is a sturdy, American-made option that balances airflow and contaminant capture, though buyers should measure their filter slot against the listed actual dimensions to ensure a precise fit.

Key Features

• MERV 14 filtration: Captures very small airborne particulates to improve indoor air quality and protect HVAC components.
• Activated carbon panel: Attracts and holds odorous gases and common VOCs for basic odor control in living spaces.
• Electrostatically charged media: Enhances particulate capture without excessively restricting airflow through the system.
• Reinforced construction: Metal mesh support grid bonded to pleats and a moisture resistant beverage board frame for durability.
• Made in the USA: Manufactured domestically, which supports consistent build quality and standards.

Who It's For

This filter is a good fit for homeowners with allergy or asthma concerns who need high-efficiency filtration and also want some odor reduction from cooking, pets, or household chemicals. It is particularly appropriate for systems that accept 4 in nominal filters and where maintaining reasonable airflow is important.

Those who should look elsewhere include people who require medical-grade filtration beyond MERV 14 or those who have HVAC slots that demand a precise 20 x 24 x 4 nominal fit without measuring - some customers reported variance between nominal and actual dimensions, so confirm the actual size before purchase.

Pros & Cons

Pros

• High filtration efficiency equivalent to MPR 2800, improving capture of fine particulates.
• Built-in activated carbon adds a layer of odor and VOC adsorption for everyday household smells.
• Sturdy construction with metal mesh and moisture resistant frame for longer service life in typical conditions.
• Made in the USA, reflecting consistent manufacturing standards.

Cons

• Actual dimensions are slightly smaller than the nominal 20 x 24 x 4 spec, so measuring is essential to ensure proper fit.
• Carbon panel provides basic odor control but is not a substitute for specialized VOC remediation in industrial or heavy-smoke situations.

It represents good value for typical residential HVAC systems, provided buyers confirm the actual dimensions before ordering to ensure the correct fit.

Frequently Asked Questions

Will this filter remove household odors?
Yes, the integrated activated carbon panel helps attract and hold many common household odors and some VOCs, though it is intended for routine odor reduction rather than heavy industrial fumes.

Is this the same as a 20 x 24 x 4 filter?
Nominally yes, but the actual size is 19 3/8 x 23 3/8 x 3 5/8 in, so measure your filter slot and compare to the actual dimensions to ensure a proper fit.

Can this filter affect HVAC airflow?
The electrostatically charged synthetic media is designed to balance filtration and airflow, but any high-MERV filter can slightly increase resistance compared with lower-rated filters; check your system specifications if airflow is critical.
