Nordic Pure 18x30x1M11MiniPleat-4 Merv 11 Air Filter 4-pack

Product Description

The NORDIC PURE 18x30x1M11MiniPleat-4 is a MERV 11 mini-pleat air filter sold in a pack of four, designed for use in residential and light-commercial HVAC systems including forced-air furnaces and central air conditioning units. The filter carries a nominal size of 18x30x1 and an actual size of 17.75 x 29.75 x 0.75 inches, which is the measurement that determines fit. The media is a self-supporting synthetic polyester fiber constructed with 2.5 times more pleats than standard filters, increasing usable surface area while maintaining adequate airflow across the system. The two-part, moisture-resistant beverage board frame holds its shape in high-humidity conditions common to return-air applications. Licensed HVAC technicians and knowledgeable service personnel install these filters as part of routine preventive maintenance schedules.

This filter is suited for residential homes and commercial spaces where indoor air quality is a priority. It captures lint, household dust, pollen, pet dander, dust mites, mold spores, smoke particles, virus carriers, and allergens. The MERV 11 rating makes it appropriate for environments with pets, allergy concerns, or elevated particulate loads such as post-renovation cleanups. Nordic Pure recommends replacing the filter every 2 to 3 months depending on the operating environment and system load. Each box contains four filters, making it practical for scheduled quarterly or semi-annual changeout programs.

Compatibility

Designed as an OEM-style replacement filter for residential and light-commercial forced-air HVAC systems accepting a nominal 18x30x1 filter. Always verify fit against the actual size of 17.75 x 29.75 x 0.75 inches, as nominal and actual sizes frequently differ across equipment makes.

Installation Notes

Filter installation is a routine maintenance task performed by licensed HVAC technicians or qualified service personnel. Always shut down the air handler or furnace at the thermostat and disconnect power at the breaker before removing the old filter. Insert the new filter with the airflow arrow on the frame pointing toward the blower. Nordic Pure recommends a replacement interval of every 2 to 3 months, though high-particulate environments may require more frequent changes.
