Nordic Pure 19x21x1ExactCustomM7-12 Merv 7 Filter 12pk

Product Description

The NORDIC PURE 19x21x1ExactCustomM7-12 is a custom-cut, pleated AC furnace air filter rated MERV 7, sold in a 12-pack. Each filter measures an actual 19 x 21 x 0.75 inches and is built around a heavy-duty, moisture-resistant beverage board frame with electrostatically charged filter media. The electrostatic charge helps attract and hold airborne particles, and the media is engineered to resist bacterial and mold growth on the filter surface. MERV 7 corresponds to approximately MPR 600 on competing rating scales, and all efficiency ratings follow the ASHRAE standard. Licensed HVAC technicians and qualified service professionals typically handle commercial installations, while homeowners commonly perform residential filter changes.

This filter is suited for residential and light commercial forced-air HVAC systems including gas furnaces, electric furnaces, and central air conditioning units. It is a custom-made product, hand-fabricated to the exact nominal dimensions of 19 x 21 x 1 by cutting down or combining standard filter frames. Tape may be used in construction depending on the final size configuration. Because this is a custom size, technicians and homeowners should measure the existing filter slot carefully before ordering. The 12-pack format supports bulk stocking for properties requiring frequent filter rotation or multi-unit service schedules.

• Electrostatically charged pleated media outperforms fiberglass panels and resists bacterial and mold growth on the filter surface
• Reinforced 2-part moisture-resistant beverage board frame provides durability and supports consistent airflow
• Made in the USA
• 12-pack quantity reduces per-unit cost and supports a 1-to-3-month replacement schedule

Compatibility

Designed as a custom OEM-style replacement filter for residential and light commercial forced-air HVAC systems accepting a nominal 19 x 21 x 1 inch filter. Verify the actual slot dimensions before ordering, as custom sizes are non-returnable.

Installation Notes

Power down or set the thermostat to off before replacing a furnace or air handler filter. Note the airflow direction arrow printed on the filter frame and orient the replacement to match. Filters in this size category are typically serviced by homeowners or HVAC technicians during routine maintenance calls. Nordic Pure recommends replacement every 1 to 3 months, with more frequent changes in homes with pets, high dust loads, or occupants with allergies.
