Nordic Pure 20x24x4 MERV 15 Plus Carbon Filters 6 Pack - Superior

In this review the Nordic Pure 20x24x4 MERV 15 Plus Carbon filters are evaluated for homeowners and light commercial users who need high-efficiency particle removal plus odor control. The bottom line: these filters deliver robust capture of airborne particulates while the activated carbon layer reduces many household odors, making them a solid choice for anyone seeking high MERV filtration and improved indoor air quality. Measure your filter slot carefully because the actual size differs slightly from the nominal size.

Key Features

• Nominal and actual sizing: The nominal size is 20 x 24 x 4 in, with an actual frame size of 19 3/8 x 23 3/8 x 3 5/8 in so customers should compare the actual measurements to their filter slot for a correct fit.
• MERV 15 performance: Rated MERV 15 and equivalent to MPR 2800, these filters capture very small airborne particles for noticeably cleaner air in living spaces and commercial units that accept high-MERV media.
• Activated carbon layer: A flat panel infused with activated charcoal attracts and holds odorous gases and vapors, helping reduce common household smells while maintaining airflow.
• Durable construction: The frame uses heavy duty, moisture resistant beverage board and a bonded metal mesh support grid for pleat stability and long service life.
• Antimicrobial media: Electrostatic synthetic media resists bacteria and mold growth, contributing to a healthier indoor environment over the filter lifespan.

Who It's For

The filters are best suited to homeowners with allergy or sensitivity concerns, small commercial spaces that can accept MERV 15 rated filters, and anyone who wants both particle removal and odor control in one unit. They appeal to buyers who prioritize capture efficiency, a solid build, and an activated carbon option rather than basic fiberglass filters.

Those who should look elsewhere include users whose HVAC slots require exact nominal dimensions without deviation, or installations that cannot support a higher-MERV, thicker media due to reduced airflow or system restrictions. Also, if only seasonal minimal filtration is required, a lower-MERV, lower-cost option may suffice.

Pros & Cons

Pros

• High particle capture with MERV 15 performance, suitable for fine particulates and pollen.
• Integrated activated carbon panel provides measurable odor reduction without blocking airflow excessively.
• Sturdy beverage board frame and metal mesh support make the filters feel well built and durable.
• Manufactured in the USA, which some buyers prefer for quality control.

Cons

• Actual dimensions are slightly smaller than nominal, so some users may find fit requires verification and care.
• Higher-MERV media can reduce airflow in systems not designed for thicker, dense filters.

Frequently Asked Questions

Are these filters the exact 20 x 24 x 4 size?
They are sold nominally as 20 x 24 x 4 in, but the actual frame measures 19 3/8 x 23 3/8 x 3 5/8 in, so measure your slot before ordering.

Will the carbon panel remove strong chemical odors?
The activated carbon layer helps attract and hold many household odorous gases and vapors, improving smell control, but very strong industrial odors may exceed its capacity.

Can my HVAC handle MERV 15 filters?
Many modern systems can, but check your HVAC specifications; high-MERV media can restrict airflow in older or undersized systems.
