Nordic Pure 20x20x5 Honeywell Replacement MERV 14 Plus Carbon - Odor

In this review of the Nordic Pure 20x20x5 Honeywell Replacement MERV 14 Plus Carbon 4 Pack, the bottom line is simple: this filter is for homeowners who want strong particle removal plus basic odor control without changing their existing furnace housing. The reviewer found these filters deliver noticeably cleaner air and reduced household smells thanks to the pleated electrostatic media and an activated charcoal panel, while the clarified actual dimensions make it clear you must measure before ordering to ensure a proper fit.

Key Features

• Actual Size: The filter lists the real measurements as 19 5/8 x 19 7/8 x 4 3/8 in, which prevents surprise fit issues when replacing nominal 20 x 20 x 5 in filters.
• MERV 14 Filtration: High-efficiency MERV 14 media captures a wide range of airborne particulates, helping improve indoor air quality for allergy sufferers and dust-prone homes.
• Carbon Odor Control: The flat panel infused with activated charcoal helps reduce common household odors and volatile organics like cooking smells.
• Honeywell Replacement: Designed to replace Honeywell 20x20x4 style filters and similar MPR-rated units that actually measure about 4 3/8 in deep, making it a practical OEM substitute.
• Made in the USA: Manufactured domestically, which some buyers prefer for perceived build consistency and supply chain transparency.

Who It's For

This filter is well suited to homeowners and renters who use standard 20 x 20 nominal filter housings and want a higher-efficiency option that also addresses odors. It works best for people looking to reduce dust, pet dander and many common household smells without changing their furnace or air handler.

People who should look elsewhere include anyone whose filter slot strictly requires a true 5 in thickness rather than an actual 4 3/8 in depth, and those needing HEPA-level filtration for medical-grade air cleaning. Always measure the existing filter to confirm the listed actual size before purchase.

Pros & Cons

Pros

• High MERV 14 performance provides strong particulate capture and improved air quality.
• Carbon layer reduces odors and common VOC smells in many homes.
• Well-built pleated media and easy installation make it a practical OEM replacement option.
• Made in the USA, which some buyers prefer for consistency.

Cons

• Actual dimensions are smaller than the nominal size, so ordering without measuring can lead to a poor fit.
• Not a substitute for certified HEPA systems if the highest medical-grade filtration is required.
