Nordic Pure 20x20x5 Honeywell Replacement MERV 8 Plus Carbon - Odor

Our review of the Nordic Pure 20x20x5 Honeywell Replacement MERV 8 Plus Carbon filters finds them best suited for homeowners who want reliable dust filtration plus basic odor control without a high-cost specialty cartridge. The bottom line: these are practical, well built furnace filters with a true actual size listed so buyers can double-check fit, and the fused carbon layer helps reduce pet and cooking smells while keeping common airborne particles at bay. For someone replacing traditional 5 filters with an actual 4 3/8 depth, these are a sensible, value-oriented choice.

Key Features

• Actual size clarity: The filter lists an actual size of 19 5/8 x 19 7/8 x 4 3/8 in so buyers can measure and ensure a proper fit rather than relying on the nominal 20 x 20 x 5 label.
• MERV 8 performance: The MERV 8 rating provides effective removal of common household dust, lint, and pollen, improving indoor air quality for many typical homes.
• Plus carbon layer: The pleated plus carbon construction traps odorous gases and vapors, making these filters useful for reducing pet and cooking smells.
• Compatible replacement: Designed to replace Honeywell 20x20x4 style filters and MPR 800 equivalents for straightforward swap-in replacement.
• Made in the USA: Domestic manufacturing offers reassurance about consistent build quality and sourcing.
• Economical pack size: Sold as a 2 pack, they provide a practical, lower-cost way to maintain filtration on a regular schedule.

Who It's For

These filters are aimed at homeowners and renters who need a dependable, mid-level filter that balances particle capture with odor reduction. If you have pets, cook frequently, or want to cut down on visible dust without upgrading to a high-MERV or specialty HEPA system, this is a useful option.

Those who need medical-grade filtration, capture of ultrafine particles, or official allergy clinic recommendations should look for higher MERV or HEPA-rated solutions. Also check your appliance slot depth carefully - these are actual 4 3/8 in filters and may not fit units that strictly require a full 5 in.

Pros & Cons

Pros

• Clear actual sizing reduces fit surprises and simplifies replacement.
• The carbon layer noticeably reduces common household odors like pets and cooking.
• Solid build quality and easy installation make them user-friendly.
• Good value as an economical alternative to OEM parts.

Cons

• Actual depth is 4 3/8 in which may differ from nominal 5 in and could cause confusion if not measured first.
• MERV 8 is not sufficient for households needing very high filtration for smoke or fine allergy particles.
