The NORDIC PURE 17x29x1ExactCustomM8+C-6 is a custom-made, pleated MERV 8 Plus Carbon air filter designed for residential and light-commercial HVAC systems, including forced-air furnaces and central air conditioning units. Each filter is hand-fabricated to exact measurements of 17 x 29 x 0.75 inches actual size, combining mechanical filtration with activated carbon media to reduce airborne allergens and common household odors. Licensed HVAC technicians and knowledgeable homeowners install these as direct replacements when standard nominal sizes do not fit the filter slot. This listing includes 6 filters per box.
This filter is suited for residential forced-air systems where a non-standard filter opening requires a custom-cut solution. Because each unit is manufactured to the exact dimensions entered at time of order, it is critical that the installer measure the existing filter opening or the current filter to the nearest 1/8 inch before ordering. The MERV 8 Plus Carbon rating makes these filters appropriate for homes with moderate dust, pet dander, pollen, and odor concerns. Filters in this 1-inch thickness category are typically replaced every 30 to 90 days depending on system runtime and indoor air quality conditions.
Designed as a custom exact-size replacement filter for residential and light-commercial forced-air furnace and central AC systems with a filter opening requiring a 17 x 29 x 1 nominal slot where standard sizes do not fit. Measure the actual filter opening to the nearest 1/8 inch before ordering, as custom sizes are non-returnable.
HVAC technicians or qualified installers should power down the air handler or furnace at the disconnect switch before removing or inserting any filter. Confirm airflow direction arrows on the filter frame align with the direction of airflow toward the blower. For 1-inch filters, plan for replacement every 30 to 90 days based on operating conditions and indoor air quality. Because this is a custom-made product, verify exact slot dimensions with a tape measure before ordering - returns are not accepted on custom sizes.
