Nordic Pure 16x25x4 Pleated Air Filter MERV 15 Plus Carbon

Our review of the Nordic Pure 16x25x4 Pleated Air Filter MERV 15 Plus Carbon concludes it is a strong choice for homeowners who need high-efficiency filtration and odor reduction in a single, easy-to-install pack. The biggest reason to buy is its combination of MERV 15 performance and an activated carbon panel that targets airborne particles and odors. The filter is designed for users who measure and match actual filter dimensions rather than relying on nominal sizes, and it is made in the USA, which adds to its appeal for buyers prioritizing domestic manufacture.

Key Features

• Nominal and actual sizes: The filter lists a nominal size of 16 x 25 x 4 and an actual size of 15 1/2 x 24 1/2 x 3 5/8 so buyers can measure their slot and ensure a correct fit.
• MERV 15 filtration: Equivalent to MPR 2800, this level of filtration captures very small particles and improves indoor air quality for allergy and asthma-conscious households.
• Plus carbon panel: An added flat panel infused with activated charcoal helps reduce common household odors in addition to particulate capture.
• Electrostatic media: The synthetic electrostatically charged media enhances particle attraction and extends effective filtration compared with plain mechanical filters.
• Made in the USA: Domestic manufacture may be important for buyers who prioritize local production and consistent quality control.

Who It's For

This filter is best for homeowners and renters who can accurately measure their existing filter slot and need high-efficiency removal of fine particles and some odor control, such as those with pets or strong cooking smells. It suits HVAC systems that accept a 4 in nominal depth filter where the actual depth of roughly 3 5/8 in will fit without leaving gaps.

Those who should look elsewhere include users who expect the nominal size to match the filter frame exactly without measuring, and systems that require the thicker 4 3/8 in actual depth commonly used by some brands; in that case, the 16x25x5 option with a different actual depth is recommended.

Pros & Cons

Pros

• High-efficiency MERV 15 performance useful for reducing fine airborne particles.
• Integrated activated carbon panel adds basic odor control beyond particle filtration.
• Electrostatically charged synthetic media increases particle capture without requiring denser pleats.

Cons

• Actual dimensions differ from nominal size and are smaller by roughly 1/2 in depth and width in some cases, so precise measurement is required to avoid gaps.

Our Verdict

The Nordic Pure 16x25x4 Plus Carbon is a sensible pick for anyone who measures their filter slot and wants near top-tier particulate filtration plus basic odor control.

Frequently Asked Questions

Will this filter fit my 16x25x4 slot?
Only if you measure your slot and confirm it accepts the actual size of 15 1/2 x 24 1/2 x 3 5/8 in; do not rely on the nominal label alone.

Does the carbon panel remove odors?
The flat activated charcoal panel provides basic odor reduction for common household smells but is not a replacement for specialized odor control systems.

Is this the same as an MPR 2800 filter?
Nordic Pure MERV 15 is stated to be equivalent to MPR 2800, offering similar particle capture performance.
