Nordic Pure 16x25x5 Honeywell Replacement MERV 15 Plus Carbon

In this review the focus is on the Nordic Pure 16x25x5 (actual 15.75 x 24.75 x 4.38 in) MERV 15 Plus Carbon air filter, aimed at homeowners and light commercial users who need high-efficiency particulate removal plus odor control. The bottom line: this filter is for people who want a high-performance replacement for Honeywell 16x25x4 units and similar MPR-rated filters, delivering strong dust and allergen capture with an activated charcoal layer to reduce common household odors. Measure your existing filter and compare actual dimensions before ordering to ensure a correct fit.

Key Features

• Actual size clarity: The listing shows the actual size 15.75 x 24.75 x 4.38 in so buyers can confirm fit rather than relying on nominal dimensions.
• MERV 15 filtration: Offers high-efficiency removal of fine particulates, making it suitable for homes concerned with dust, pollen and many airborne allergens.
• Plus carbon layer: A flat panel infused with activated charcoal helps reduce common household odors and some VOCs.
• Replacement compatibility: Designed to replace Honeywell 16x25x4 and similar MPR-rated filters with an actual depth of 4.38 in for a wide range of furnaces and A/C housings.
• Electrostatic media: Pleated synthetic material is electrostatically charged to attract and retain particles more effectively than plain mechanical media.
• Made in the USA: Manufactured domestically, which may matter to buyers who prioritize local production.

Who It's For

This filter is best for homeowners with allergy concerns or dusty environments who need strong particulate removal without switching to a whole-house air purifier. It also fits light commercial units and furnace housings that accept a filter with an actual 4.38 in depth.

Buyers should measure their filter slot and compare to the stated actual dimensions before purchasing; those who cannot accommodate the slightly deeper actual depth or who require true 5 in thickness from a specific manufacturer may need to look for other options.

Pros & Cons

Pros

• High MERV 15 rating for effective removal of fine dust and allergens.
• Activated charcoal panel provides added odor control compared with standard pleated filters.
• Actual dimensions are listed, helping users confirm fit before buying.
• Good value for buyers seeking both filtration and odor reduction in a single filter.

Cons

• Actual size differs from nominal size, so incorrect fit is possible if buyers rely on nominal measurements.
• Some customers report occasional variance in dimensions between batches, so careful measurement is advised.
