True product
Great price for a 12 pack. Works very good. Had a problem with coughing a lot. But, since these Merv 13 Trufilters, I have no more issues
User
Clean cool air.
Very good filters. Used them to keep dirt/dust out of home and out of the of furnace. Would not change now, used long enough to determine these are really good filters.plus they are MERV 11. Buying bulk(6) saves money Better filters and at great price.

This captures the things you’ll be glad you missed when you change the filter
I live in an apartment where they supply us with filters, but they’re the kind you can basically see-through, if you know what I mean. I’m in downtown Dallas so there’s plenty of particles in the air. This filter captures them, instead of recirculating them back into my place. The MERV number is a great balance that doesn’t put too much pressure on the AC unit landing with a perfect balance of clean cool air, or in the winter, warm clean air. When I change the filter, I’m amazed at what I have been fortunate enough to miss breathing in. I highly recommend these.. i did quite a bit of comparisons and find this to be a great value.

Noticeable improvement in air quality!
These BNX TruFilter MERV 13 filters are excellent! The air quality in my home has noticeably improved since I started using them. They catch so much more dust, pet dander, and allergens than basic filters. The construction feels sturdy and they fit perfectly. Great value for the quality — highly recommend for anyone who wants cleaner indoor air!

Cleaner air on the way!
Air quality is important so get a product that provides that for your family. We have pets and these really filter out what comes with them. You will see improvement in your air quality with the first use. Added plus .. made in America! When the Canadian firefighters smoke came through, these really helped to filter that smell out. That was an unexpected plus. Easy to install and great for allergy sufferers.

Quality and Saving Money
I don't know what's so special about furnace filters. The prices keep going up and now they're at a point of being a budget buster, so I said enough of this silly game. These are great filters and saved me a lot of money in the process. They are made from thick cardboard and so are durable and have no visible deficiencies. That leaves me with about $30 to spend of something fun. I'm done with the big box stores raising prices - this is such an easy way to take a stand and save some money. Kudos to BNX for making a great product and keeping the price reasonable!

Excellent Filter
Immediately noticed a difference in the airflow! Upstairs A/C slim duct system is working very efficiently. 10/10 would recommend.

Buen producto, mal envío.
Muy buen producto! Se ve de buena calidad, pero el empacado utiliza empaque que no protege los filtros. Tristemente llegó dañado y no se ve que puedan llegar en buena calidad. Amazon me apoyó con una devolución inmediatamente 👍
