Nordic Pure 20x24x1 MERV 13 Plus Carbon Pleated Filters 4 Pack

In this review the Nordic Pure 20x24x1 MERV 13 Plus Carbon pleated filters are evaluated for homeowners and allergy sufferers who want stronger particle capture plus odor control. The bottom line: these filters combine a high-efficiency electrostatically charged pleated media with an added activated charcoal panel to trap fine dust, smoke and VOCs while maintaining airflow, making them a solid choice for anyone concerned about indoor air quality. Measure your existing filter against the listed actual size before buying to ensure a correct fit.

Key Features

• Actual size clarity: The filter lists an actual size of 19 1/2 x 23 7/16 x 3/4 in so customers can compare measurements for a proper fit.
• MERV 13 filtration: The electrostatically charged synthetic pleated media captures fine particles such as dust, pollen and some smoke for cleaner indoor air.
• Activated carbon layer: A flat panel infused with activated charcoal helps attract and hold odorous gases and VOCs to reduce unwanted smells.
• Support and durability: The pleats are reinforced with a bonded metal mesh and a heavy duty beverage board frame for moisture resistance and longer life.
• Made in the USA: Manufactured domestically, which many buyers prefer for perceived quality and local support.
• Recommended replacement: Nordic Pure suggests changing 1 in filters every 30-90 days depending on use and conditions to maintain performance.

Who It's For

These filters are best for households that want superior particulate capture plus some odor control, for example homes affected by smog, smoke or persistent cooking smells, and for people who prioritize air quality around allergies and respiratory concerns. The combination of a MERV 13 pleated media and an activated charcoal panel makes them useful where both particles and odors are an issue.

They are less suitable for systems that require exact nominal sizing without measurement: several customers note concerns about the final measured size, so anyone who cannot confirm fit or has an unusual filter slot may prefer to measure carefully or select a different thickness. Installers should confirm the actual dimensions before purchasing.

Pros & Cons

Pros
