Nordic Pure 16x25x5 Honeywell Replacement Filter - MERV 12 + Carbon (2 Pack)

Overview

Elevate your indoor air quality with the Nordic Pure 16x25x5 Honeywell replacement filter, engineered with a dual material design that pairs dense MERV 12 filtration with an activated carbon layer. This combination helps target odorous gases and vapors while preserving strong airflow for steady comfort in homes and small workplaces.

Important sizing note: Almost ALL furnace filters have a different "actual size" than the nominal size printed. For the best fit, measure your current filter and compare it to the product’s actual size. Nordic Pure 16x25x5 Honeywell replacements list an actual depth of 4 3/8 inches, a common variance you may encounter across brands. The specified actual dimensions are 15 3/4 x 24 3/4 x 4 3/8 (15.75 x 24.75 x 4.38) to help you verify compatibility with your HVAC cabinet.

What makes this filter stand out

The filter media blends a high-efficiency MERV 12 pleated layer with a carbon-backed layer. This dual-action design aims to maintain robust airflow while providing odor control and adsorption of volatile compounds, giving you a more neutral air experience without sacrificing filtration performance.

Construction and durability

Nordic Pure builds with a heavy-duty, moisture-resistant beverage board frame that resists warping in damp environments. A metal mesh support grid is bonded to the pleats, offering added rigidity to help the filter retain its shape during operation and replacement cycles.

The 12-month to 6-month replacement cadence is guidance for typical use; actual timing depends on system load, environmental factors, and equipment location. The media design, combined with the carbon layer, can contribute to a longer-lasting filtration feel by reducing odors and maintaining steady airflow.
