Nordic Pure 16x20x4 Pleated MERV 13 Plus Carbon Filters - 6 Pack

In this review the Nordic Pure 16x20x4 Pleated Air Filters MERV 13 Plus Carbon are evaluated for homeowners who want higher particle capture plus mild odor control without changing filter depth. The bottom line: these filters are a solid choice for those who need MERV 13 filtration and an activated carbon layer in a common nominal 16 x 20 x 4 package, but buyers must measure their furnace slot since the actual size differs from the nominal size.

Key Features

• Actual vs nominal size: The filter lists an actual size of 15 1/2 x 19 1/2 x 3 5/8 in so users can confirm fit before purchase to avoid loose gaps or tight fits.
• MERV 13 performance: The synthetic pleated media provides fine particle capture equivalent to MPR 2200-2400, which helps reduce airborne particulates and allergens in living spaces.
• Plus carbon layer: A flat panel infused with activated charcoal adds mild odor adsorption for common household smells without adding significant airflow restriction.
• Electrostatically charged media: The pleated synthetic material uses static charge to attract and hold smaller particles for improved filtration efficiency.
• Made in the USA: The filters are manufactured domestically, which can be important for buyers prioritizing locally made HVAC parts.

Who It's For

These filters suit homeowners and renters who run central HVAC systems and want elevated particle filtration plus some odor control in a 16 x 20 x 4 nominal size. They are a good option for allergy-prone households that need MERV 13 performance and prefer synthetic, pleated filters with activated carbon.

Measure the existing filter before ordering: because the actual size is 15 1/2 x 19 1/2 x 3 5/8 in, people with furnace slots that require a deeper actual depth (for example 4 3/8 in) should choose the 16x20x5 replacement referenced by the brand instead.

Pros & Cons

• High capture efficiency with MERV 13 equivalent media for finer particle removal and allergy relief.
• Added activated carbon for basic odor reduction in homes with routine cooking or pet smells.

Frequently Asked Questions

Do these filters fit every 16 x 20 x 4 slot?

How effective is the carbon layer?
The flat panel of activated charcoal provides light to moderate odor adsorption for common household smells but is not intended to replace specialty odor-control systems.

Are these filters equivalent to MPR 2200-2400?
Yes, Nordic Pure states the MERV 13 media is equivalent to MPR 2200-2400 for particle capture.
