BNX TruFilter 20x20x1 MERV 13 (4-Pack) AC Furnace Air Filter - MADE IN USA - Electrostatic Pleated Air Conditioner HVAC AC Furnace Filters - Removes Pollen, Mold, Bacteria, SmokeOEKO-TEX STANDARD 100

I’ve been using the BNX TruFilter MERV 13 filters for a few months now, and I’m genuinely impressed with their performance. These filters are well-constructed, fit perfectly in my HVAC system, and noticeably improve the air quality in my home.What I love most is how effective they are at capturing dust, pollen, and even smoke particles. As someone with seasonal allergies, I’ve noticed a significant reduction in sneezing and congestion since switching to these. The electrostatic pleated design seems to do a great job without restricting airflow, which is a big plus.Also, the fact that they’re made in the USA and come with sustainability certifications gives me extra peace of mind. The 4-pack is a great value, and I appreciate the option to subscribe and save.Highly recommend these if you’re looking for a reliable, high-performance air filter!

These are great air filters! Well made, efficient, perfect size, prevent allergens and dust, and very well priced. I will be purchasing this product for my air filters from now on!

We have used these for the last three years, changing every three months. They are easy to install, bending slightly to slide into the bracket. They fit perfectly. We have never had a bad filter i.e. they are built well. Not enthusing about furnace filters, but these do exactly what they are supposed to do at a very reasonable price.

These filters are a good value for the money. I've ordered two different sizes and they fit as they should and are easy to install. The quality and thickness is what you'd expect for the price. I will most likely order again.

The BNX filters are great quality, well-made, clean the air of dust and allergens, made in the USA, and all at a great price. The ‘slim fit’ make them easy to install and fit perfectly in our new AC unit. We will be setting them up on subscribe and save. HIGHLY RECOMMEND!

Great filter! Fits good and is never a problem to install. The airflow direction is clearly marked. Great value for the money as they are sturdy and help with pets and allergies.

I purchased the BNX TruFilter 20x20x2 MERV 13 (4-Pack) for a home project. I built a Corsi-Rosenthal box to help clean the air in my detached garage. The filters worked perfectly for the setup. Solid construction, consistent airflow, and easy to seal with tape.I mounted the unit up high and out of the way to maximize space. Now, whenever I’m working in the garage, I turn it on and can actually feel the difference. It gives me peace of mind knowing the air I’m breathing is cleaner.If you're looking to build your own DIY purifier or just want reliable high-quality filters for your HVAC system, this is a great option.

These are good quality USA-made filters. They are well constructed, fit perfectly, work well trap a lot of airborne dust and pet hair. We have ordered BNX filters a few times and they always arrive in perfect condition. I just changed the latest filter today. I will post a photo of the filter when we change it out. They usually last us a month. I highly recommend these.
