Nordic Pure 25x25x1 MERV 13 Plus Carbon Pleated Air Filters - 2 Pack

In this review the Nordic Pure 25x25x1 MERV 13 Plus Carbon pleated air filters are evaluated for homeowners and allergy sufferers who need high-efficiency filtration plus basic odor control. The bottom line: these filters deliver MERV 13 particle capture with an added activated carbon panel that helps reduce common household odors while maintaining good airflow, making them a practical choice for furnaces and HVAC systems where both dust removal and odor mitigation matter.

Key Features

• Actual dimensions: The filters measure 24 1/2 x 24 1/2 x 3/4 in, so users should measure their filter slot and compare to the actual size for a proper fit.
• MERV 13 efficiency: Equivalent to MPR 2200-2400, the MERV 13 rating captures fine airborne particulates that commonly trigger allergies and reduce indoor air quality.
• Activated carbon panel: A flat panel infused with activated charcoal attracts and holds odorous gases and VOCs, helping diminish household smells.
• Electrostatically charged media: Permanently charged synthetic material improves dust capture by helping particles cling to the filter fibers without excessive airflow restriction.
• Durable construction: Heavy duty, moisture-resistant beverage board frame and bonded metal mesh support provide extra sturdiness and pleat support for reliable service life.

Who It's For

These filters are aimed at homeowners, renters, and anyone maintaining a residential HVAC or furnace system who wants higher-efficiency particle removal plus some odor control. They are particularly useful for people with allergies or households with pets where both fine dust and odors are a concern.

They are not intended for specialty medical or clean-room environments that require HEPA-level filtration, and customers who need a thicker filter depth than 1 in should look for models with greater thickness to match their system's filter slot.

Pros & Cons

Pros

• High-efficiency MERV 13 media captures fine dust and common allergens for improved indoor air quality.
• Built-in activated carbon panel provides basic odor reduction for everyday household smells and VOCs.
• Sturdy beverage board frame and metal mesh support make the filters feel durable and hold pleat shape during use.
• Electrostatically charged synthetic material enhances dust attraction without overly restricting airflow.

Cons

• Actual size is 24 1/2 x 24 1/2 x 3/4 in, so buyers must measure; a few customers noted size variation compared with nominal sizing.

Frequently Asked Questions

Will these filters reduce pet odors?
Yes, the activated carbon panel helps attract and hold many common pet odors and household VOCs, though very strong or chemical smells may need specialized filtration.

Do these replace 1 in filters?
The nominal size is 25 x 25 x 1 in but the actual thickness is 3/4 in (24 1/2 x 24 1/2 x 3/4 in), so confirm your filter slot before ordering.

How long do they last?
Longevity depends on use and indoor air conditions, but the sturdy frame and electrostatically charged media are designed for typical monthly to quarterly replacement intervals used with MERV 13 filters.
