20x20x1 (19_1/2x19_1/2) Nordic Pure Tru Mini Pleat MERV 11 Air Filters 4 Pack

Nordic Pure MERV 11 Tru Mini Pleat AC Furnace Air Filters deliver excellent filtration for homes and commercial spaces. These mini-pleat air filters have 2.5 times more pleats than standard filters, offering greater surface area to effectively capture and remove harmful airborne particles. The increased pleats enhance efficiency without restricting airflow, saving money on HVAC maintenance and extending filter life. Thanks to their larger filtration area, Tru Mini Pleat filters can last longer than the traditional pleated filters. Constructed with a durable 2-part, moisture-resistant beverage board frame and self-supporting synthetic polyester fiber media, Nordic Pure filters effectively attract unwanted particles like lint, household dust, pollen, pet dander, smoke particles, and allergens.  For consistently fresh and clean air, especially during renovations or home improvements, we recommend replacing your HVAC filter every 2-3 months, depending on your environment. Important Note: Furnace filters often have different Actual Sizes (exact measurements) compared to Nominal Sizes (printed sizes). Always measure your current filter and compare it to our Actual Size to ensure a proper fit.
