Nordic Pure 20x20x5 Furnace Filter MERV 14 Plus Carbon

In this review the Nordic Pure 20x20x5 (actual 19 5/8 x 19 7/8 x 4 3/8 in) replacement furnace filters are evaluated for homeowners who want better particulate and odor control without changing their system. The bottom line: this two-pack with a MERV 14 rating and an activated charcoal panel is best for anyone seeking noticeably cleaner air and reduced household odors, provided you measure your current filter first since the actual size differs from the nominal label.

Key Features

• Actual size clarity: The filter lists the true dimensions 19 5/8 x 19 7/8 x 4 3/8 in so buyers can measure and confirm fit before purchase.
• MERV 14 performance: High filtration captures a wide range of airborne particles, making it useful for homes with allergies or pets.
• Activated carbon layer: The Pleated Plus Carbon design helps reduce common household odors and volatile organic compounds for fresher indoor air.
• Replacement compatibility: Designed to replace Honeywell 20x20x4 filters and other units with a similar actual depth of 4 3/8 in for an OEM-style swap.
• Made in the USA: Domestic manufacturing gives reassurance about quality and consistent construction.
• Two-pack value: Sold as a pair, it provides a straightforward spare for the next filter change cycle.

Who It's For

This filter is aimed at homeowners and renters who need enhanced filtration beyond basic fiberglass filters and who also want odor reduction from an activated charcoal panel. It suits families with mild to moderate allergy concerns, pet owners, or anyone sensitive to cooking and household smells.

It is not the right choice for someone who cannot confirm the actual filter depth beforehand or for systems that require a true 5 in depth rather than a nominal 5 that measures 4 3/8 in. Always measure the existing filter and compare to the listed actual size to avoid fit issues.

Pros & Cons

Pros

• High-efficiency MERV 14 media removes fine particulates that lower-rated filters miss.
• Carbon-infused panel helps neutralize common household odors and VOCs.
• Clear actual dimensions reduce the chance of buying the wrong size when measured correctly.
• Well-made and easy to install according to customers who report good fit and build quality.

Cons

• Actual dimensions are smaller than the nominal 20 x 20 x 5 label, and some buyers find the size discrepancy surprising if they do not measure first.
