Nordic Pure 25x25x1 Pure Carbon Pleated Odor Reduction Filters 6 Pack

In this review the Nordic Pure 25x25x1 Pure Carbon Pleated Odor Reduction filters are assessed for homeowners and light commercial users who need odor control without sacrificing airflow. The bottom line: these filters combine a pleated design with activated carbon to reduce smells and VOCs while still fitting standard furnace and A/C housings. The reviewer finds them best as a durable, mid-efficiency option that captures dust and helps with household odors, making them a practical choice for apartments, allergy-conscious households, or as a pre-filter in higher-performance HVAC systems.

Key Features

• Pleated carbon media: The pleated design delivers more carbon surface area to help absorb odors and VOCs while maintaining efficient airflow through the system.
• Durable frame: A heavy duty, moisture resistant beverage board frame holds the filter rigidly in place and resists degradation in damp environments.
• Support grid: Metal mesh bonded to the pleats provides extra structural support so the media keeps its shape under airflow.
• Anti-microbial media: The non-woven polyester media will not support mold or bacterial growth, improving indoor air quality over time.
• Made in the USA: Domestic manufacturing means consistent build quality and materials for each pack of filters.

Who It's For

The filters are well suited for residential users in apartments or houses who want better odor control than a flat fiberglass filter can provide; they are also useful for small businesses or industrial settings as a pre-filter to help reduce strong smells before air reaches a high-efficiency stage. Homeowners with seasonal allergy concerns who also face odor issues will find the combination of dust capture and carbon adsorption beneficial.

Those looking for high-MERV, hospital-grade filtration or true HEPA-level particle removal should look elsewhere, since these filters are approximately MERV 8 and are intended to balance odor reduction with airflow rather than maximize particle capture.

Pros & Cons

Pros

• Effective odor adsorption thanks to activated carbon infused media.
• Sturdy construction with a moisture resistant frame and metal mesh support for long service life.

Cons

• Approximately MERV 8 means it is not designed for hospital-grade or HEPA-level particle removal.

Frequently Asked Questions

Do these filters reduce household odors?
Yes, the activated carbon infused media is formulated to absorb odors and VOCs, helping reduce common household smells.

Will they fit standard 25 x 25 x 1 slots?
The nominal size is 25 x 25 x 1, while the actual dimensions are 24 1/2 x 24 1/2 x 3/4 in, so they fit most standard housings but check your slot clearance for the slightly smaller actual size.

Are these suitable for allergy sufferers?
They help capture dust and some particulates and improve air quality for many users, but they are approximately MERV 8 and not a substitute for HEPA filtration for severe allergies.
