We’ll see how much stuff these things catch in 3 months. Good value for the money as replacement filters.

Slightly higher filtration levels with these as well as a lower price. Won’t be using one for a month or so, but visual inspection shows good quality construction

High filtration at a good price

I received these furnace filters as part of the companys testing program. Overall, I would say these filters are comparable to other filters of the same MERV13 spec. I have been using these filters for about a month now, and can say that I have not noticed a drastic difference in comparison to other filters I have used. I would consider this a good thing in that there is not obvious decline in quality since switching to these filters. As you can see in my third picture, the in-use filter has turned black/gray so it would appear that it is doing its job. Pricing per filter is comparable, and may even be slightly more expensive, than some brands. I do like that these are an American-made product! A few things I have noticed, these filters do not do quite as good of a job at filtering out odors as the carbon-infused MERV11 filters I have used in the past. Also, all 4 of my filters I received were sealed within the same bag. I wish they would be individually sealed to avoid dust and particle contamination during storage until they are used. Other buyers have expressed some concerns over product durability and manufacturing quality. As you can see in my pictures, the filter grooves are not uniformly spaced across the entire filter. Good filter overall. Happy to support American-made products. Will consider purchasing them again when the time comes for me to purchase more filters.

I have been buying this brand for a few years already and for the money they are solid and work well with my 3 ton centralized a/c unit. I have a cat and a dog that shed so much I wonder if they would go bald one day. I change them every month and no a/c coil issues so far.

Had smokers in the house so bought these to help remove the smell, fantastic! Well worth the extra money

Extremely well designed filter

The construction quality of the filters seems to imply that the quality of the filter media can be counted on. The filter media is supported by what appears to be an aluminum mesh mounted within a cross-linked cardboard frame fully self-supporting that fits well in my blower unit.

Mervyn 13 great quality and price.

Thankful
