Quality is slipping

I have been purchasing these filters for years. But this last set of filters I received looked to be assembled so fast that nothing aligned and there were gaps between the bevels.

These are replacements for the Honeywell MERV 13 filters we have been using. American made and appear excellent. I expect they will be fine, but we have just installed them. I'll know better in 3-4 months. Much less expensive.

I use 20x20 filters with box fans for cheap air filtration, so I go through them quickly, these have a higher merv for less than half the price of the filters I used to use.

Do not fit.

Even though they say the right size, they are way too small and I cannot use them. I think they are just the wrong kind of filter. Can I please return them for a refund? Please let me know how to go about the return.

24x24x4 MERV 13 Pleated Air Filter
on July 7, 2025
Posted by: Priscila B.
[This review was collected as part of a promotion.] The 24x24x4 MERV 13 Pleated Air Filter is a high-efficiency filtration solution designed for commercial HVAC systems that require superior air quality. After testing and installing multiple units in a facility with moderate to heavy air circulation demands, here's a breakdown of its performance and overall value:Performance:The MERV 13 rating offers excellent filtration, capturing airborne particles as small as 0. 3 microns. This includes allergens like pollen, dust mites, mold spores, pet dander, and even bacteria and virus carriers. Its particularly beneficial in environments prioritizing indoor air qualityoffices, churches, schools, healthcare facilities, and multi-use buildings.Build Quality:This filter features a durable pleated design with a rigid frame that holds up well under consistent airflow. The pleats are evenly spaced and well-constructed, maximizing surface area for particle capture without causing significant pressure drop. The filter media is moisture-resistant and doesnt sag or collapse under typical HVAC stress.Installation:Standard sizing ensures a snug and proper fit into most 24x24x4 filter racks or housings. Installation is straightforward and hassle-free, with clear directional airflow markings on the frame. The rigid design helps prevent bowing or bypass.Longevity:With normal use, the filter lasts approximately 36 months depending on air quality and system usage. Facilities with higher occupancy or environmental pollutants may require more frequent replacements, but the filter maintains integrity over its full lifespan.Value:While priced slightly higher than lower-rated filters (MERV 8 or MERV 11), the performance upgrade is well worth the investment, especially for facilities aiming to improve IAQ (Indoor Air Quality) and reduce strain on HVAC systems over time.Overall Rating: (4. 8/5)The 24x24x4 MERV 13 Pleated Air Filter is a reliable, high-performance choice for those needing enhanced air filtration without compromising HVAC system efficiency. Its durability, ease of use, and exceptional filtering capabilities make it a solid go-to option for professional facility management and maintenance.
