Nordic Pure 18x25x1M11MiniPleat-3 Merv 11 Mini Pleat Filter

Product Description

The NORDIC PURE 18x25x1M11MiniPleat-3 is a MERV 11 Tru Mini Pleat air filter sold in a 3-pack, designed for residential and light commercial HVAC systems including forced-air furnaces and central air conditioners. The filter media is self-supporting synthetic polyester fiber housed in a heavy-duty, moisture-resistant two-part beverage board frame. With 2.5 times more pleats than standard flat-panel filters, the increased surface area improves particle capture efficiency while maintaining adequate airflow across the system. The nominal size is 18x25x1; the actual size is 17.5 x 24.5 x 0.75 inches. HVAC technicians and service professionals should always verify actual dimensions before installation.

This filter is suited for residential homes and commercial spaces where improved indoor air quality is a priority. It captures lint, household dust, pollen, pet dander, dust mites, mold spores, smoke particles, virus carriers, and allergens at a MERV 11 rating, equivalent to MPR 1000-1200. It is particularly effective in environments with elevated particulate loads such as during renovations or home improvement projects. Replacement is recommended every 2-3 months depending on operating conditions and environment.

Compatibility

Designed as an OEM-style replacement for residential and light commercial HVAC systems requiring a nominal 18x25x1 filter. Always verify the actual filter opening dimensions against the actual size of 17.5 x 24.5 x 0.75 inches before installation, as nominal and actual sizes differ across equipment manufacturers.

Installation Notes

Filter installation should be performed by a qualified HVAC technician or experienced service professional. Always shut down the HVAC system at the thermostat and disconnect power at the breaker before removing or installing any air filter. Confirm airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Follow local mechanical codes and manufacturer guidelines for filter maintenance intervals.
