Nordic Pure 13x21_3/4x1ExactCustomM8+C-6 Merv 8 Carbon Filter

Product Description

The NORDIC PURE 13x21_3/4x1ExactCustomM8+C-6 is a custom-made, pleated MERV 8 plus carbon air filter designed for residential and light commercial HVAC systems. Built to exact dimensions of 13 inches by 21.75 inches by 0.75 inches, this filter combines mechanical particle capture with an activated carbon layer to reduce common airborne allergens and household odors. It is sold in a 6-pack. The reinforced 2-part frame adds structural durability to support consistent airflow and filtration performance over the life of the filter. Installation is handled by homeowners or HVAC technicians servicing forced-air furnace and air conditioning systems.

This filter is intended for forced-air furnace and central air conditioning systems that require a non-standard custom fit. Because the actual dimensions are fractional, this filter is hand-cut to the exact measurements specified at the time of order. It is appropriate for residential environments where standard nominal filter sizes do not match the filter cabinet opening. MERV 8 filtration captures particles in the 3-10 micron range, making it suitable for households with dust, pollen, pet dander, or mild odor concerns. Filters in this 1-inch thickness category should be replaced every 30 to 90 days depending on environmental conditions.

Key Features

• Custom exact-fit dimensions: 13 inches x 21.75 inches x 0.75 inches - hand-made to order
• MERV 8 rating captures 70 to 85 percent of airborne particles between 3 and 10 microns, including lint, dust, pollen, pet dander, and mold spores
• Activated carbon layer helps reduce household odors alongside standard particulate filtration
• Reinforced 2-part frame provides added structural support and balanced airflow resistance
• Sold as a 6-pack, reducing reorder frequency for routine filter maintenance
• Made in the USA

Compatibility

Designed as a custom exact-fit replacement for residential and light commercial forced-air furnace and central AC systems with a filter cabinet opening that matches the nominal size of 13 x 21-3/4 x 1 inches. Because this is a custom-made size, verify actual opening dimensions with a tape measure before ordering. Custom sizes are not eligible for return.

Installation Notes

Power down the furnace or air handler at the thermostat and disconnect switch before replacing the filter. Confirm the actual filter slot dimensions with a tape measure prior to ordering, as this product is custom-cut and cannot be returned. Insert the filter with the airflow arrow on the frame pointing toward the blower. For 1-inch filters, plan to replace on a 30-to-90-day cycle based on household dust and air quality conditions.
