Nordic Pure 13x20x1ExactCustomM13+C-12 Merv 13 Carbon Filter

Product Description

The NORDIC PURE 13x20x1ExactCustomM13+C-12 is a custom-cut, MERV 13 plus carbon pleated air filter designed for residential and light commercial AC and furnace systems. Built from electrostatically charged synthetic media, it captures airborne particulates down to 0.3 microns while the integrated carbon layer helps reduce odors. Each filter measures an actual 13 x 20 x 0.75 inches and ships in a 12-pack. The reinforced 2-part frame adds structural durability to support consistent airflow over the full service life of the filter. Licensed HVAC technicians and knowledgeable DIYers install this filter in forced-air systems where standard nominal sizing does not fit.

This filter is suited for residential and light commercial forced-air HVAC systems that require an exact custom fit in place of standard nominal sizes. The 13 x 20 x 1 nominal slot is a less common dimension, making the custom-cut construction critical for a proper seal and maximum filtration efficiency. The carbon-enhanced media addresses applications where odor control is a priority alongside particulate capture, such as homes with pets, cooking activity, or smoke exposure. Twelve filters per box supports a full year or more of regular filter changes on a 30-to-90-day replacement schedule.

Key Features

• MERV 13 rating captures over 90% of airborne particles between 1-10 microns and 50%-70% of particles between 0.3-1 microns, including dust, pollen, pet dander, mold spores, smoke, bacteria, and viruses
• Integrated carbon layer reduces common household odors from cooking, pets, and smoke
• Electrostatically charged synthetic media attracts and holds fine particulates without restricting airflow
• Reinforced 2-part frame provides added structural durability for consistent performance over time
• Custom-cut to exact dimensions (actual size: 13 x 20 x 0.75 inches) for a proper seal in non-standard filter slots
• Made in the USA

Compatibility

Custom-made to the exact dimensions listed; designed as a direct fit for forced-air AC and furnace systems with a filter slot requiring an actual dimension of 13 x 20 x 0.75 inches. Verify your current filter actual size with a tape measure before ordering. Custom sizes are non-returnable.

Installation Notes

Installation is performed by licensed HVAC technicians or qualified DIYers. Power down the furnace or air handler at the disconnect or thermostat before removing the old filter. Confirm airflow direction marked on the filter frame aligns with the direction of airflow in the system. Replace every 30 to 90 days depending on indoor air quality conditions and system run time.
