Nordic Pure 12x20x1 MERV 12 Pleated Plus Carbon 6 Pack - Odor Control

In this review the Nordic Pure 12x20x1 MERV 12 Pleated Plus Carbon 6 Pack is examined for homeowners and renters who need stronger filtration with odor control. The bottom line: this pack is best for those who want a step up from basic filters, because the fused carbon layer tackles common household smells while the MERV 12 media captures fine dust and pollen. The reviewer found the build solid, air flow acceptable for most systems, and the fitted dimensions require checking against the furnace slot to avoid surprises.

Key Features

• MERV 12 filtration: Captures fine dust, pollen and many airborne particles so indoor air feels noticeably cleaner in living spaces.
• Plus carbon layer: Activated carbon is fused to the pleated media to attract and hold odorous gases and VOCs, reducing common household smells.
• Dual material construction: The MERV media bonded to carbon preserves airflow while adding odor adsorption for balanced performance.
• Durable frame: Heavy duty, moisture resistant beverage board frame gives the filter a sturdy fit and resists warping in humid conditions.
• Electrostatic charge: Permanently charged media helps particles cling to the filter fibers, improving capture without drastically increasing resistance.
• Made in the USA: Domestic manufacture provides consistent quality and materials sourced under US production standards.

Who It's For

The Nordic Pure MERV 12 Plus Carbon is suited to homeowners or apartment dwellers who want better particle removal than a basic disposable filter and also need odor control from cooking, pets, or everyday VOCs. It's a good fit where allergy reduction and improved overall air quality matter.

People with HVAC systems that require exact nominal sizing should measure their filter slot carefully and compare to the actual size listed, since some customers noted the physical dimensions can be slightly different from expectations. Those needing very high-efficiency hospital-grade filtration or specialized industrial odor treatment should look elsewhere.

Pros & Cons

• Actual size is 11 1/2 x 19 1/2 x 3/4 in so buyers must measure carefully; a few customers reported size surprises.
