Nordic Pure 20x20x4 Pleated Air Filter, MERV 12, 2 Pack

Premium filtration for home comfort

Nordic Pure 20x20x4 Pleated Air Filters blend a rugged, moisture‑resistant frame with electrostatically charged media to help capture a wide range of indoor particulates. This 2‑pack is designed to support your HVAC system while maintaining clearer air between replacements. The filter’s actual size is 19.5 x 19.5 x 3.63 inches, which you should compare against your unit’s opening for an accurate fit. Understanding the difference between nominal and actual sizes helps prevent surprises during installation.

Key features and benefits

• Actual size clearly listed to enable correct fit (19.5 x 19.5 x 3.63 inches).
• MERV 12 filtration, equivalent to MPR 1500–1900, for elevated particle capture.
• Electrostatically charged synthetic media attracts and holds airborne particulates.
• Heavy‑duty moisture‑resistant beverage board frame with a bonded metal mesh for added stability.
• Made in the USA, reflecting a focus on consistent quality and supply.

What to expect in everyday use

• Particles such as pollen, fine dust, smoke residues, spores, and related irritants are more likely to be captured before circulating back into living spaces.
• The media design helps support HVAC efficiency by reducing buildup and maintaining steady airflow.
• Regular replacement helps sustain performance and energy efficiency over time.

Fit, maintenance, and usage tips

• Measure your furnace or return filter slot and compare to the listed actual size to ensure a proper seal.
• If you’re replacing a Honeywell/Lennox filter with a 4 3/8 depth, consider the 20x20x5 option to match that depth.
• Typical replacement interval is 3–6 months, depending on usage, environment, and comfort needs.
• Note: The media does not kill germs; it helps reduce microbial growth risk and minimizes the need for chemical additives.
