Nordic Pure 18x24x1 MERV 12 Pleated Plus Carbon Filters - Odor Control

In this review the Nordic Pure 18x24x1 MERV 12 Pleated Plus Carbon filter is evaluated for homeowners and renters who need stronger filtration and odor control without sacrificing airflow. The bottom line: this 12-pack is best for people who want a long-running pleated filter rated roughly equivalent to MPR 1500-1900 that also captures odors via an activated carbon layer. It is a practical, well-constructed option made in the USA, but buyers should measure their filter slot carefully because the listed nominal size differs from the actual framed dimensions.

Key Features

• MERV 12 filtration: Captures a wide range of airborne particulates, offering improved indoor air quality for homes with pets or higher dust loads.
• Activated carbon layer: Adsorbs common odorous gases and vapors so rooms smell fresher when the system runs.
• Pleated electrostatic media: Permanently charged material helps attract and hold fine dust while maintaining good airflow through the system.
• Sturdy frame and support: Beverage board frame and bonded metal mesh give the filter shape stability and moisture resistance during use.
• Actual vs nominal size guidance: Actual dimensions are 17 1/2 x 23 1/2 x 3/4 in, and the listing warns buyers to measure their filter slot to ensure a correct fit.

Who It's For

This filter pack is a sensible choice for households that need both particulate filtration and odor reduction, such as homes with smokers, strong cooking smells, or pets. It is also appropriate for people who want a higher-grade filter (MERV 12 equivalent to MPR 1500-1900) that still allows reasonable airflow in central HVAC systems.

Those who should look elsewhere include people whose furnaces or filter slots require exact nominal sizing without any variation, or anyone needing specialized HEPA-level filtration for severe allergies. Also measure the slot first, since some customers report mixed fit results against the 18 x 24 x 1 nominal label.

Pros & Cons

Pros

• Effective mix of particulate capture and odor control thanks to the combined MERV media and carbon layer.
• Solid build quality with a moisture-resistant beverage board frame and metal mesh support.
• Good airflow characteristics relative to filtration level, making it compatible with many central HVAC systems.

Cons

• Actual size is 17 1/2 x 23 1/2 x 3/4 in while the nominal label reads 18 x 24 x 1, so careful measurement is required to avoid fit issues.

Our Verdict

Frequently Asked Questions

Will this filter reduce odors from cooking and pets?
Yes. The activated carbon layer adsorbs many common odorous gases and vapors, helping reduce smells when the system cycles.

Does MERV 12 restrict airflow in a typical home system?
MERV 12 offers higher filtration but Nordic Pure designs this pleated media to maintain reasonable airflow; still check your system compatibility if it is sensitive to restrictive filters.

Why do some customers report fit issues?
The product lists a nominal size of 18 x 24 x 1 in but the actual framed dimensions are 17 1/2 x 23 1/2 x 3/4 in, so measure your filter slot and compare to the actual size before installation.
