Nordic Pure 16x25x4 Pleated Air Filters MERV 14 Plus Carbon 6 Pack

In this review the Nordic Pure 16x25x4 Pleated Air Filters MERV 14 Plus Carbon 6 Pack is evaluated for homeowners and renters who need higher-efficiency filtration with odor control. The bottom line: it is a good-value, made-in-USA pleated filter that removes a wide range of airborne particulates while offering a charcoal layer for mild odor reduction. Measure your existing filter before ordering because the nominal size differs from the actual size and fit is the single most important factor when choosing these filters.

Key Features

• Actual size guidance: The filter lists an actual size of 15 1/2 x 24 1/2 x 3 5/8 in so buyers can compare measurements and avoid a poor fit.
• MERV 14 filtration: High-efficiency media captures a wide range of fine particles, roughly equivalent to MPR 2800, useful for reducing dust and allergens.
• Plus carbon layer: An infused flat panel of activated charcoal helps reduce common household odors and VOCs more effectively than pleated media alone.
• Electrostatically charged media: Synthetic pleats are electrostatically charged to improve particle capture without adding excess airflow resistance in most systems.
• Made in the USA: Domestic manufacture can be important for buyers who prioritize origin and consistent quality control.

Who It's For

This pack is best for homeowners or tenants with HVAC systems that accept a 4 in nominal filter but require checking the actual size, who want stronger filtration than basic fiberglass or low-MERV pleats. It suits those who also want some odor control from an activated charcoal layer in high-traffic living areas, kitchens, or pet homes.

It is not ideal for systems that require the slightly deeper 4 3/8 in actual depth filters or equipment that is very sensitive to precise filter thickness; customers who need a deeper replacement for specific Honeywell or Lennox units should choose the 16x25x5 (4 3/8 actual depth) option instead.

Pros & Cons

Pros

• High MERV 14 performance offers strong particle capture for dust, pollen, and many allergens.
• Built-in activated charcoal panel provides added odor control versus standard pleated filters.
• Clear actual size labeling helps buyers measure and match for a proper fit.

Cons

• Actual depth is slightly less than some competing 4 in listings, and a few users report a small gap if the system expects a different actual thickness.

Our Verdict

The Nordic Pure 16x25x4 MERV 14 Plus Carbon 6 Pack is a practical choice for consumers who need high-efficiency filtration plus modest odor reduction at a reasonable price. It delivers solid particle capture and the charcoal layer adds value, but buyers must measure their existing filter slot to ensure the 15 1/2 x 24 1/2 x 3 5/8 in actual size will fit without gaps. For systems that accept the listed actual depth, it represents good value and reliable performance.

Frequently Asked Questions

Do these filters include a charcoal layer for odors?
Yes, each filter has an integrated flat panel infused with activated charcoal to help reduce common household odors.

Will this replace Honeywell 16x25x4 filters?
Possibly, but check the actual depth of your Honeywell filter; some Honeywell units use a 4 3/8 in actual depth and those require the 16x25x5 Honeywell replacement option.

What size should I measure before ordering?
Measure your current filter and compare to the listed actual size of 15 1/2 x 24 1/2 x 3 5/8 in to ensure a proper fit and avoid gaps.
