Nordic Pure 18x27x1CustomM7+C-6 Merv 7 Carbon Filter

Product Description

The NORDIC PURE 18x27x1CustomM7+C-6 is a custom-cut, MERV 7 plus carbon pleated air filter designed for residential and light commercial HVAC systems. It combines electrostatically charged synthetic filter media with an activated carbon layer to capture airborne particulates and reduce common household odors in a single pass. The actual dimensions are 17.5 inches by 26.5 inches by 0.75 inches, fitting a nominal 18x27x1 filter slot. Sold in a six-pack, this filter is manufactured in the USA and built into a reinforced two-part frame for added structural rigidity. HVAC technicians and homeowners install it in furnaces and central air handlers where a custom slot size is required.

This filter is suited for residential forced-air heating and cooling systems where the return air opening requires a non-standard filter size. The MERV 7 rating targets particles in the 3 to 10 micron range, making it appropriate for households dealing with dust, pollen, pet dander, lint, mold spores, and similar common allergens. The added carbon layer addresses odor reduction beyond what standard MERV 7 media alone provides. Because this is a custom-fabricated product cut to the nominal 18x27x1 specification, it is not a stock size and is manufactured to order. HVAC service professionals and property managers sourcing filters for non-standard equipment should confirm the actual slot measurement before ordering.

Key Features

• MERV 7 rating captures 50 to 70 percent of airborne particles between 3 and 10 microns, including dust, pollen, pet dander, and mold spores
• Activated carbon layer reduces common household odors beyond standard particulate filtration
• Electrostatically charged synthetic media enhances particle attraction without significantly restricting airflow
• Reinforced two-part frame provides added durability compared to standard single-frame construction
• Custom-fabricated to nominal 18x27x1 dimensions with an actual size of 17.5 x 26.5 x 0.75 inches
• Made in the USA; sold in a six-pack

Compatibility

Designed as a custom-size OEM-style replacement filter for residential and light commercial forced-air HVAC systems requiring a nominal 18x27x1 filter slot. Confirm the actual opening dimensions before ordering, as custom sizes are non-returnable.

Installation Notes

Installation is performed by HVAC technicians or qualified service personnel. Always shut down the air handler or furnace at the disconnect or breaker before removing or installing the filter. Confirm airflow direction marked on the filter frame matches the direction of airflow in the system before seating the filter. Nordic Pure recommends replacing this filter every 30 to 90 days depending on environmental conditions and system usage; higher-dust or higher-occupancy environments will require more frequent changes.
