Nordic Pure 20x25x4 Pleated Air Filter – MERV 12 with Carbon, 2-Pack

Overview

Enhance your built in air system with the Nordic Pure 20x25x4 Pleated Air Filter with Carbon. This dual layer design blends a MERV rated filtration media with an activated carbon layer to address both particle capture and odor considerations. The filter is designed to fit 20x25x4 slots when measured accurately, with an actual size of 19.5 x 24.5 x 3.63 inches for proper fit guidance.

Why this filter stands out

The filter uses a fusion of MERV rated material and carbon to support layered filtration and odor control. It also features a thicker surface area that translates into more material for air to pass through, which can contribute to a more balanced air feel in busy living spaces. The 19.5 x 24.5 x 3.63 inch actual size helps you avoid fit issues in many standard HVAC slots.

• Dual material fusion combines MERV rated media with a carbon layer for layered performance.
• 33% more surface area for potential odor control and fresher air cues.
• Heavy duty, moisture resistant beverage board frame for durability in varied environments.
• Metal mesh support grid bonded to the pleats adds rigidity and longevity.
• MERV 12 rating aligns with common HVAC standards and is comparable to MPR 1500-1900.
• Made in the USA, supporting domestic manufacturing and consistent supply.

Fit, maintenance, and planning

Nominal size is 20 x 25 x 4, but the actual size is 19.5 x 24.5 x 3.63. Always measure your air filter for exact size and compare to the actual size to ensure a proper fit. If you are replacing a Honeywell or Lennox 20x25x4 Plus Carbon or a filter with an actual depth of 4 3/8, consider our 20x25x5 option for the correct depth.

• We recommend changing filters every 3–6 months to maintain efficiency and economy.
• This product is sold as a 2 pack for easy replacement planning.

Overall, Nordic Pure 20x25x4 with carbon offers a practical approach to support regular HVAC maintenance while aiming to contribute to a fresher indoor environment. While outcomes can vary by system and usage, the design focuses on delivering solid filtration performance and odor management possibilities.
