Nordic Pure 20x20x5 Odor Reduction MERV 8 Filter - Carbon Pleated

In this review of the Nordic Pure 20x20x5 odor reduction filter, the bottom line is simple: it is for homeowners and renters who want an economical, no-fuss replacement filter that reduces odors and captures everyday airborne particles. The reviewer found the activated carbon pleated media noticeably reduced common household smells and improved perceived air quality, while remaining easy to install and compatible as a Honeywell/Lennox replacement. Measure your existing filter first, because the unit uses an actual size that differs from the nominal stamp.

Key Features

• Actual vs nominal size: The filter lists a nominal 20 x 20 x 5 H but the actual dimensions are 19 5/8 x 19 7/8 x 4 3/8 in, so measuring first avoids fit problems.
• Activated carbon media: Naturally derived charcoal infused into the pleated media helps reduce indoor odors, smoke and VOCs for fresher-smelling rooms.
• Improved pleated design: The pleated media uses about three times the carbon content compared with flat panel carbon filters, boosting odor adsorption without loose carbon dust.
• No messy carbon particles: Carbon is infused into the polyester base so there are no loose granules to shed into ducts or vents, making installation cleaner.
• Made in the USA: Proudly manufactured in the USA, which supports local production and consistent build quality.
• MERV 8 particle capture: The filter captures dust and common allergens while also addressing odors, improving general indoor air quality.

Who It's For

This filter is ideal for people who want an OEM-style replacement that tackles both odors and dust in typical home environments, such as kitchens, living rooms, and apartments where cooking smells or smoke are occasional concerns. It suits owners of Honeywell or Lennox systems who need a pleated 5 in style filter but will accept an actual 4 3/8 in depth.

Those with severe respiratory sensitivities or who require high-efficiency particulate removal should consider higher MERV options or HEPA solutions instead, because this model balances odor adsorption with moderate particle capture rather than medical-grade filtration.

Pros & Cons

Pros

• Effective odor reduction from carbon-infused pleats improves room smell without messy loose carbon.
• Good build quality and fit for many OEM replacements, with easy installation.
• Made in the USA and offers better carbon loading compared with flat panel alternatives.

Cons

• Actual dimensions are smaller than the nominal size, so measuring the existing filter is required to ensure proper fit.
• MERV 8 provides moderate particle capture but is not intended for high-allergen or clinical filtration needs.

Frequently Asked Questions

Will this filter stop strong cooking smells?

Is the carbon loose or messy?
No, the carbon is infused into the pleated polyester media so there are no loose carbon granules during installation or use.

Does the nominal size match the actual size?
No, the nominal 20 x 20 x 5 in label differs from the actual 19 5/8 x 19 7/8 x 4 3/8 in dimensions, so measure your existing filter before purchasing.
