Nordic Pure 20x25x4 Pleated Air Filters MERV 14 Plus Carbon - 2 Pack

In this review the Nordic Pure 20x25x4 Pleated Air Filters MERV 14 Plus Carbon 2 Pack is assessed for homeowners who want stronger particle capture and mild odor reduction without changing HVAC hardware. The bottom line: these filters deliver solid filtration performance thanks to a MERV 14 pleated media and an activated charcoal panel, making them a good fit for houses where dust, pet dander and common household odors are a concern. The review also flags fit issues: measure your current filter, because the listed nominal size differs from the actual size and that can affect installation.

Key Features

• Actual size guidance: The filter lists an actual size of 19 1/2 x 24 1/2 x 3 5/8, so measuring your filter pocket first reduces the chance of a loose or too-small fit.
• MERV 14 performance: High-efficiency pleated synthetic media captures a wide range of airborne particulates for better indoor air quality compared with lower-rated filters.
• Plus carbon panel: A flat panel infused with activated charcoal helps reduce common household odors and light VOC smells in addition to particulates.
• Compatibility note: Nordic Pure states MERV 14 is equivalent to MPR 2800 and provides guidance when replacing other brands or depths to avoid ordering the wrong actual depth.
• Made in the USA: The filters are manufactured domestically, which can be important for buyers preferring local production and quality control.

Who It's For

This product is aimed at homeowners with central furnaces or air handlers who need stronger filtration than basic fiberglass or low-MERV pleats, and who want some odor reduction from a charcoal panel. It suits people with allergies, pets or dusty environments who can accommodate a deeper pleated filter in their system.

It is not ideal for anyone who cannot accept a difference between nominal and actual sizes or who requires an exact 4 3/8 in actual depth; those users should measure their existing filter and consider Nordic Pure sizes specified for that actual depth to avoid a loose fit.

Pros & Cons

Pros

• Good particulate removal with MERV 14 media for homes with allergy or dust concerns.
• Activated charcoal panel provides extra odor control compared with standard pleated filters.
• Easy to slide into place if your filter pocket matches the actual dimensions; customers reported straightforward installation.

Cons

• Actual size differs from nominal size and some customers report a loose fit or the filter being noticeably smaller than expected, so careful measurement is required.

Our Verdict

The Nordic Pure 20x25x4 MERV 14 Plus Carbon two-pack is a strong choice for homeowners who need higher-efficiency particulate capture plus mild odor control at a reasonable price; it represents good value when the actual dimensions match the filter slot. Measure the existing filter first and choose the correct actual depth variant if your system uses a deeper 4 3/8 in actual filter to avoid fit issues.

Frequently Asked Questions

Will this filter fit my 20 x 25 x 4 slot?
Measure your current filter and compare to the listed actual size of 19 1/2 x 24 1/2 x 3 5/8 in; this product uses that actual size not the nominal size.

Does the charcoal panel remove household odors?
The flat panel with activated charcoal helps reduce common odors and light VOC smells but is not meant to eliminate strong industrial odors.

Is this the same depth as Honeywell 4 3/8 in filters?
No; Honeywell 4 3/8 in actual depth filters require a different Nordic Pure size listed for 4 3/8 actual depth to ensure correct fit.
