Nordic Pure 20x25x4 Pleated Air Filter MERV 7 Plus Carbon - Cleaner

In this review the Nordic Pure 20x25x4 Pleated Air Filter MERV 7 plus carbon is evaluated for homeowners who want basic particulate removal with odor reduction in a single, economical filter. The bottom line: it is a practical replacement for common 20 x 25 x 4 nominal filters when the actual size of 19 1/2 x 24 1/2 x 3 5/8 fits the unit, and its added activated charcoal panel helps reduce light household odors while the MERV 7 media captures most dust and large particulates. Measure your filter slot first to avoid fit issues noted by some buyers.

Key Features

• Actual size guidance: The filter lists an actual size of 19 1/2 x 24 1/2 x 3 5/8 in so buyers can compare before ordering to ensure a proper fit.
• MERV 7 performance: The MERV 7 rating, equivalent to MPR 600, captures common household dust, pollen and lint without adding excessive airflow resistance.
• Plus carbon panel: A flat panel infused with activated charcoal helps reduce light odors from cooking or pets alongside particulate removal.
• Synthetic electrostatic media: The charged pleated material increases particle capture efficiency for everyday airborne debris in HVAC systems.
• Made in the USA: The filter is produced domestically, which may appeal to buyers prioritizing local manufacturing and quality control.
• Compatibility note: If replacing a 4 3/8 in depth filter from certain brands, the 20x25x5 option should be considered instead to match actual depth.

Who It's For

This filter is best for homeowners and renters with HVAC systems that accept a 20 x 25 x 4 nominal filter but whose filter compartment accommodates the actual dimensions of 19 1/2 x 24 1/2 x 3 5/8 in. It suits people who want a balance of dust capture and mild odor control without a high-MERV, high-restriction media.

It is not ideal for those who require high-efficiency filtration for allergy or medical reasons, or for owners of units that need a thicker 4 3/8 in actual depth filter; measure closely because several customers reported sizing and thickness confusion when they relied on nominal dimensions alone.

Pros & Cons

Pros

• Good value for routine dust capture and basic indoor air improvement in typical homes.
• Activated charcoal panel helps with light odors, adding a useful secondary benefit.
• Made of electrostatically charged synthetic media, improving particle adhesion without heavy airflow loss.
• Clear actual size labeling helps buyers match the filter to their unit when measured correctly.

Cons

• Some customers reported fit issues and perceived the thickness as smaller than expected, so measurement is essential before purchase.
• Not a replacement for high-MERV or medical-grade filtration if specialized allergen or smoke removal is required.

Our Verdict

The Nordic Pure 20x25x4 Pleated Air Filter MERV 7 plus carbon is a sensible, cost-effective choice for everyday homes that need reliable dust removal and modest odor control.

Frequently Asked Questions

What size should I measure to confirm fit?
Measure your existing filter to confirm the actual dimensions and compare to the listed actual size of 19 1/2 x 24 1/2 x 3 5/8 in.

Is this filter suitable for allergy sufferers?
It helps with everyday dust and pollen but is MERV 7, so those needing higher allergen or smoke filtration should choose a higher MERV option.

Can this replace a Honeywell 20x25x4?
Possibly, but if your Honeywell filter has a 4 3/8 in actual depth you should choose the 20x25x5 option that matches that depth.
