Nordic Pure 20x20x1 MERV 13 Plus Carbon Pleated Filters - Odor Control

In this review of the Nordic Pure 20x20x1 MERV 13 Plus Carbon pleated air filters, the bottom line is straightforward: these filters are aimed at homeowners who want high-efficiency particle capture plus basic odor control without spending on costly OEM replacements. The combination of a permanently electrostatically charged synthetic media and a flat panel infused with activated charcoal means the filter both attracts fine dust and helps reduce common household odors and VOCs. Measure your filter slot against the actual size to ensure a correct fit before buying.

Key Features

• MERV 13 filtration: Captures a wide range of airborne particulates, including finer dust and pollen, for cleaner indoor air.
• Activated carbon panel: Helps adsorb odorous gases and common household vapors to reduce smells without blocking airflow.
• Electrostatically charged media: Acts like a magnet to improve dust clinging and particle retention compared with plain fiberglass filters.
• Sturdy construction: Heavy duty beverage board frame and metal mesh support provide moisture resistance and pleat support for longer life.
• Made in the USA: Domestic manufacturing offers consistent build quality and materials sourcing.

Who It's For

The Nordic Pure MERV 13 Plus Carbon is best for homeowners or renters with forced-air systems who want stronger particle filtration than basic disposable filters and also need some odor control from cooking, pets, or household chemicals. It is appropriate where higher filtration is needed for allergy mitigation or to reduce fine dust in living spaces.

It is less appropriate for systems that require exact nominal sizing without tolerance; customers who need a guaranteed manufacturer OEM fit should carefully compare the actual size 19 1/2 x 19 1/2 x 3/4 in to their filter slot, and those requiring heavy-duty industrial VOC removal should consider dedicated carbon canisters or specialty media.

Pros & Cons

Pros

• High particle capture from the MERV 13 media helps reduce dust and allergens in the home.
• Added activated charcoal panel provides a noticeable reduction in common household odors and VOCs.
• Durable frame and bonded metal mesh deliver dependable structural support across the pleats.
• Good value compared with higher-priced name-brand equivalents while maintaining quality construction.

Cons

• Actual dimensions are 19 1/2 x 19 1/2 x 3/4 in, and a minority of customers report fit discrepancies versus other brands, so measuring before purchase is advised.
• Some users report mixed impressions of airflow; while design maintains flow, very sensitive HVAC systems should monitor pressure drop after installation.

Our Verdict

The Nordic Pure 20x20x1 MERV 13 Plus Carbon filter is a strong choice for homeowners wanting improved particle removal plus light odor control at a reasonable price.

Frequently Asked Questions

Will this filter fit a 20 x 20 x 1 in slot?
Yes, but check your slot and compare to the actual size 19 1/2 x 19 1/2 x 3/4 in to ensure proper fit before purchasing.

Does the carbon layer eliminate all odors?
The activated carbon helps adsorb many common household odors and VOCs, but it is not a substitute for specialized gas-phase filters for heavy chemical exposure.

How often should I replace these filters?
Replacement depends on use and indoor conditions, but typical residential replacement intervals apply; monitor airflow and visible dust buildup to decide timing.
