Nordic Pure 16x25x5 Honeywell Replacement MERV 10 Filter - Carbon

In this review the Nordic Pure 16x25x5 Honeywell replacement filter is evaluated for homeowners and renters who need reliable particulate and odor control without specialty HVAC service. The bottom line: this pleated MERV 10 plus carbon filter is best for people who want stronger dust removal than basic fiberglass filters and some odor adsorption from the activated carbon layer. Our review finds it offers consistent fit for many furnaces when you measure the actual size, good value for ongoing replacements, and solid performance for everyday dust and VOC reduction.

Key Features

• Actual vs nominal sizing: The filter uses an explicit actual size of 15.75 x 24.75 x 4.38 in so buyers can measure their slot to confirm proper fit and avoid common mismatches.
• MERV 10 filtration: Captures a wide range of household particles while maintaining airflow suitable for most residential HVAC systems.
• Activated carbon layer: A fused carbon material is included to attract and hold odorous gases and some VOCs, improving home air freshness beyond particle capture alone.
• Replacement for Honeywell 16x25x4: Presented as compatible with Honeywell 16x25x4 and similar filters that have an actual depth near 4.38 in, simplifying shopping for OEM-style replacements.
• Made in the USA: Manufactured domestically, which may appeal to buyers seeking locally made components and consistent production standards.
• Value packaging: The 1 pack format suits those replacing a single filter at a time and evaluating fit before committing to multi-packs.

Who It's For

This filter is a solid choice for occupants with dust allergies who need better particle capture than basic filters, and for households that notice mild odors where an activated carbon layer can help. It also suits DIY homeowners who measure their filter slot and want a dependable OEM-style replacement.

It is not the best option for people who require hospital-grade filtration or HEPA-level particle removal, nor for systems that strictly need a different actual depth. If you cannot confirm the actual size of your existing filter, measure first rather than relying on nominal dimensions.

Pros & Cons

• Clear actual size listing helps reduce fit errors when installers measure the physical filter slot.

Frequently Asked Questions

Will this filter fit my 16 x 25 slot?
Check the physical filter slot and compare to the actual size 15.75 x 24.75 x 4.38 in; the nominal 16 x 25 x 5 in label is not the true measurement.

Does the carbon layer remove odors?
The activated carbon layer helps adsorb some odorous gases and VOCs but is not a substitute for specialized odor removal systems for heavy contamination.

Is this equivalent to MPR 1000?
Yes, Nordic Pure lists the MERV 10 rating as equivalent to MPR 1000, suitable for general residential particle control.
