Nordic Pure 20x25x1 Pleated MERV 12 Air Filters 6 Pack - High

Our review of the Nordic Pure 20x25x1 pleated MERV 12 air filters finds them best suited for homeowners and small offices seeking higher-efficiency filtration without specialty equipment. The bottom line: these filters deliver improved indoor air quality by capturing finer particles than standard filters, and they come in a convenient 6 pack for regular replacement. The review notes the actual size is 19 1/2 x 24 1/2 x 3/4, so measuring your filter slot before purchase is important to ensure a proper fit.

Key Features

• Nominal and actual sizing: The package lists a nominal 20 x 25 x 1 size with an actual card frame size of 19 1/2 x 24 1/2 x 3/4, which helps buyers confirm fit before installation.
• MERV 12 efficiency: The filter rating captures smaller particles than basic filters and is comparable to MPR 1500-1900, making it useful for reducing dust and common allergens.
• Electrostatically charged media: The charge improves particle capture for dust and odors without adding extra resistance to most residential systems.
• Durable frame: A heavy duty, moisture resistant beverage board frame keeps the filter square and stable in typical HVAC housings.
• Made in the USA: Domestic manufacturing can be a deciding factor for buyers who prefer locally produced HVAC parts.

Who It's For

This filter pack is ideal for homeowners or small commercial spaces that want better filtration than standard cheap fiberglass filters provide, particularly where occupants have moderate allergies or asthma and need improved air filtration. The six-pack format also suits those who replace filters seasonally or every 1-3 months.

Those who should look elsewhere include anyone whose system requires nonstandard dimensions or ultra-high-efficiency medical-grade filtration; also check fit carefully if your filter slot tolerances are exact, since some users reported a slight size discrepancy.

Pros & Cons

Pros

• Good particle capture for residential use thanks to MERV 12 performance.
• Electrostatically charged media and a moisture resistant frame improve longevity and effectiveness.
• Six-pack offers convenient replacements and strong value for routine maintenance.

Cons

• Actual dimensions are 19 1/2 x 24 1/2 x 3/4, and a few customers found the filters a quarter-inch short for some slots, so measure before buying.
