The NORDIC PURE 28x34x1CustomM8+C-6 is a custom-made pleated carbon air filter rated MERV 8, sized at a nominal 28x34x1 inches with actual dimensions of 27.75 x 33.75 x 0.75 inches. It ships in a six-pack and is hand-built to the exact measurements specified at the time of order. The activated carbon layer addresses common household and light-commercial odors, while the pleated media captures airborne particles in the 3 to 10 micron range at a 70 to 85 percent efficiency rate. The reinforced two-part frame is designed to maintain structural integrity and support consistent airflow throughout the filter service life. HVAC technicians and knowledgeable homeowners install this filter in forced-air furnace and air handler systems.
This filter is suited for residential and light-commercial forced-air HVAC systems that require a non-standard custom filter size. Because it is cut and assembled to order from 1, 2, or 3 standard filter frames - with tape joining used where necessary - it fits openings that standard stock sizes cannot accommodate. Nordic Pure recommends replacing 1-inch filters every 30 to 90 days depending on local air quality, occupancy, and the presence of pets or allergens. The carbon media layer provides additional odor reduction beyond what a standard MERV 8 filter offers, making it a practical choice for installations where cooking, pet, or environmental odors are a concern.
Designed as a custom OEM-style replacement for residential and light-commercial forced-air furnace and air handler systems requiring a nominal 28x34x1 inch filter opening. Because this is a custom size, verify the actual opening dimensions before ordering. The actual filter measures 27.75 x 33.75 x 0.75 inches; the opening should accept a filter within 1/8 inch of those dimensions.
Installation is performed by licensed HVAC technicians or qualified service personnel. Power down the air handler or furnace at the disconnect or breaker before removing the existing filter to prevent unfiltered air from passing through the system during changeout. Note airflow direction arrows on the filter frame and orient the replacement filter to match before seating it in the rack. Because this is a custom-made product built to the dimensions entered at the time of order, confirm exact opening measurements with a tape measure prior to ordering - custom filters are not eligible for return.
