Nordic Pure 21x27x1CustomM13-6 Merv 13 Furnace Filter 6 Pack

Product Description

The NORDIC PURE 21x27x1CustomM13-6 is a custom-made, MERV 13 pleated air filter designed for residential and light commercial HVAC systems including forced-air furnaces and central air conditioners. Sold in a 6-pack, each filter measures an actual size of 20.5 x 26.25 x 0.75 inches with a nominal size of 21 x 27 x 1 inches. The filter media is electrostatically charged to attract and capture airborne particles, and the frame is constructed from a heavy-duty, moisture-resistant beverage board. MERV 13 filtration captures over 90 percent of airborne particles between 1 and 10 microns and 50 to 70 percent of particles between 0.3 and 1 microns. Licensed HVAC technicians and qualified service professionals install and replace these filters during routine maintenance calls.

This filter is suited for residential and commercial forced-air systems where enhanced indoor air quality is required. It is rated MERV 13, which is comparable to MPR 2200-2400 on proprietary filter rating scales. MERV 13 performance is defined by ASHRAE standards, making it appropriate for environments where occupants have allergies, asthma, or sensitivity to airborne contaminants such as pet dander, mold spores, smoke particles, bacteria, and virus carriers. Filter replacement is recommended every 1 to 3 months, with more frequent changes in high-pet or high-allergen environments. This is a custom-fabricated size; the actual dimensions govern the fit, not the nominal label.

Key Features

• MERV 13 rated per ASHRAE standards - captures over 90 percent of particles from 1 to 10 microns including pollen, dust, mold spores, pet dander, smoke, bacteria, and virus carriers
• Actual size 20.5 x 26.25 x 0.75 inches; nominal size 21 x 27 x 1 inches - verify actual dimensions before ordering
• Electrostatically charged filter media enhances particle attraction without significantly restricting airflow
• Heavy-duty, moisture-resistant beverage board frame with reinforced 2-part construction for added durability
• Media will not promote the growth of bacteria or mold on the filter surface
• Made in the USA; sold in a 6-pack

Compatibility

Custom-fabricated as an OEM-style replacement for residential and light commercial forced-air furnace and central AC systems requiring a nominal 21 x 27 x 1 inch filter slot. Verify the actual opening dimensions of your filter housing before ordering, as custom sizes cannot be returned.

Installation Notes

Filter replacement is a routine HVAC maintenance task performed by licensed technicians or qualified facility personnel. Power down the air handler or furnace at the disconnect before opening the filter access panel. Confirm airflow direction arrows on the filter frame align with the direction of air movement toward the blower. Because this is a custom-fabricated filter, measure the actual filter cavity - not the label on the existing filter - to confirm the correct size before placing an order.
