Proof is in the pudding

I purchased two filters on February 18th. I've used the competitor's filter in the past, but when I ran across this brand online, I decided to give it a try. I am elderly, live in an apartment that is old (but well maintained by maintenance) and have a history of bronchitis due to allergies. I wouldn't have purchased these filters had I not been impressed with the details stated. . In short (or in long), I feel very good about my decision to purchase. So far, so good.

from traditional cheap ones to top of the line. They only last a week or two but you got to keep buying. The buying process is nice and having it auto shipped is great.

Once I figured out that these filters easily swapped out for the electric filter that came with the New Heat Pump. I was overjoyed!

With the amount of dust and dirt in the air in New Mexico I need a good filter and I have been on a subscription since 2024 but purchased these Merv 13 filters longer than that and love them. I get them cheaper than any place in town and will continue to get them as long as I am responsible for doing the filters in our house.
