Nordic Pure 16x20x4 Pleated Air Filters MERV 15 Plus Carbon - 6 Pack

In this review the Nordic Pure 16x20x4 Pleated Air Filters MERV 15 Plus Carbon are examined for homeowners and maintenance pros who want stronger particle capture plus odor control. The bottom line: these filters deliver high filtration efficiency and an activated charcoal layer for added odor adsorption, making them a sensible upgrade for those concerned about particles and smells; however, accurate measurement is essential because the nominal 16 x 20 x 4 label differs from the filter's actual dimensions.

Key Features

• MERV 15 performance: Captures a wide range of fine particles, providing improved indoor air quality compared with lower MERV ratings.
• Plus Carbon layer: Includes an activated charcoal panel to help reduce common household odors and VOCs that particulate-only filters miss.
• Actual size guidance: The filter lists an actual size of 15 1/2 x 19 1/2 x 3 5/8 in so users can measure their slot and avoid fit issues.
• Equivalent rating: Nordic Pure MERV 15 is equivalent to MPR 2800, so it can be matched to systems that reference MPR instead of MERV.
• Made in the USA: Manufactured domestically, which some buyers prefer for consistency and sourcing transparency.

Who It's For

These filters suit homeowners, renters, and small commercial properties seeking high-efficiency filtration plus odor reduction in a standard 16 x 20 x 4 nominal slot. They are a good choice when indoor air concerns include dust, fine particulates and occasional household smells from cooking or pets.

Measure the existing filter before ordering: customers with furnace or return vent slots that require an actual depth closer to 4 3/8 in (often used by some Honeywell or Lennox units) should consider the 16x20x5 replacement with a 4 3/8 actual depth instead, because the listed actual size here can be narrower than some slots.

Pros & Cons

Pros

• High filtration efficiency from the MERV 15 media for fine particle capture.
• Integrated carbon panel helps reduce odors beyond particle filtration alone.
• Clear actual dimensions listed so buyers can verify fit before installation.
• Made in the USA, which supports local manufacturing standards.

Cons

• Actual size has a narrower footprint than the nominal label, and some customers report the filter can be slightly too small for certain furnace slots.
• The 3 5/8 in actual depth means it is not interchangeable with 4 3/8 in depth filters without checking fit.

Our Verdict

For buyers who measure carefully and need high-efficiency particle removal plus odor adsorption, the Nordic Pure 16x20x4 MERV 15 Plus Carbon 6 pack is a practical, cost-effective choice.

Frequently Asked Questions

Will this fit my 16 x 20 x 4 slot?
Check the existing filter dimensions; the nominal label reads 16 x 20 x 4 but the actual size is 15 1/2 x 19 1/2 x 3 5/8 in, so measure the opening to ensure a correct fit.

Does the carbon layer remove odors?
Yes, the flat panel infused with activated charcoal helps absorb common household odors and some VOCs in addition to particle capture.

Is this the same as an MPR 2800 filter?
Nordic Pure MERV 15 is equivalent to MPR 2800, so it aligns with systems specified by that MPR rating.
