Nordic Pure 20x25x5 Honeywell Replacement MERV 10 Plus Carbon - Odor

In this review of the Nordic Pure 20x25x5 Honeywell Replacement air filters, the bottom line is simple: these are a practical choice for homeowners who need reliable dust capture and light odor control without spending on top-tier commercial filters. The reviewer found the dual-layer pleated construction with an activated carbon layer effective at reducing dust, pet hair and mild VOC odors, and notes the importance of measuring the existing filter since the actual size differs from the nominal size. Overall, this pack suits people after solid filtration and value rather than premium hospital-grade performance.

Key Features

• Actual vs Nominal Size: The filter lists a nominal size of 20 x 25 x 5 H but an actual size of 19 7/8 x 24 7/8 x 4 3/8 so measuring your filter slot ensures proper fit.
• MERV 10 Filtration: MERV 10 material provides effective removal of common household dust and larger particulates while maintaining acceptable airflow for most residential systems.
• Carbon Layer for Odors: The pleated plus carbon design uses an activated carbon layer fused to the media to attract and hold odorous gases and light VOCs for improved indoor air smell control.
• Honeywell Replacement Fit: Designed to replace Honeywell 20x25x4 filters and similar units with an actual depth near 4 3/8 in, making swap-in replacement straightforward when sizes match.
• Made in the USA: Manufactured domestically, which can be important for buyers who prefer US-made HVAC components.
• Pack Size and Value: Sold as a 2 pack, it provides immediate replacements at a lower price than many brand-name single filters, offering solid value for routine maintenance.

Who It's For

This filter is best for homeowners and renters with forced-air HVAC systems who want an upgrade from basic fiberglass filters without the airflow restrictions of higher MERV ratings. It is a sensible pick for households with pets or moderate dust accumulation that also want some odor reduction from cooking or cleaning chemicals.

Those who need hospital-grade filtration, strong chemical filtration for heavy VOC sources, or an exact nominal-to-actual depth match without measuring should look elsewhere. Also measure the filter slot carefully, since several users report the actual depth can make the filter feel slightly long for a nominal 20x25x5 slot.

Pros & Cons

Pros

Cons

• Actual dimensions differ from the nominal size and some customers report it can be slightly too long for certain 20x25x5 openings, so measuring is essential.

Our Verdict

The Nordic Pure 20x25x5 Honeywell Replacement MERV 10 Plus Carbon filters are a practical, value-minded choice for typical homes that need improved dust capture and light odor control.

For routine HVAC maintenance and modest odor reduction, these filters represent good value.
