Excellent Value & Improved Air Quality
I recently replaced my old HVAC filter with the BNX TruFilter 20x25x1 Air Filter (MERV 8), and I’m really impressed. Installation was super simple — it fit perfectly and slid right into my system with no fuss. The build feels sturdy and well-made, not flimsy like some cheaper filters. Since using it, I’ve noticed a significant decrease in dust buildup around my house, and my air feels cleaner overall. With a MERV 8 rating, it does a great job capturing common airborne particles like dust, pollen, and pet dander — which has been especially helpful since I have pets. For the price, this is a great quality filter that performs better than expected. Definitely recommend it if you want an affordable way to improve your home’s air quality without spending a lot.

Great quality
These BNX TruFilter MERV 11 air filters work really well. The quality feels solid and well-made, and they fit perfectly in our HVAC system. Installation was easy and the filters hold their shape, unlike some cheaper ones that bend or collapse. We noticed an improvement in air quality pretty quickly — less dust in the house and fewer allergy symptoms, especially with pets. I also appreciate that they’re made in the USA and come in a convenient 6-pack, which makes replacing filters on schedule much easier. Airflow is still good while providing solid filtration. Overall, great value for the price and a reliable choice for homes with pets, allergies, or dust issues. Would definitely repurchase.

Good quality for what you pay for.
Good quality for the price and not flimsy like the cheap ones Walmart sell, plus the price is lot better. Fits my furnace with no problems and the size is exactly the same. Will buy more when need to.

Fit is tight, but great filter
We almost returned this 6-pack because the fit was surprisingly snug. My husband and I tried four times to get it properly seated in our wall vent, pushing and adjusting each corner until it finally clicked into place. Once installed, however, it's been fantastic. The air from our vents feels noticeably fresher, and my husband's allergy symptoms have lessened. We also appreciate that it's made in the USA and the frame feels sturdier than some flimsy ones we've used before. Despite the initial installation hassle, the performance makes it worth it, and we'll definitely keep using them.

Superior Air Filtration That Noticeably Improves Indoor Air Quality
After struggling with seasonal allergies and indoor air quality issues for years, discovering the BNX TruFilter MERV 13 air filters has been transformative for my home environment. These American-made filters have genuinely improved my quality of life, and I notice a significant difference in how I feel when I'm at home compared to before using them. The MERV 13 rating is the perfect balance of filtration efficiency and airflow. These filters capture an impressive range of airborne particles including pollen, mold spores, pet dander, dust mites, and even some bacteria and viruses. Since installing them in my HVAC system, I've experienced a dramatic reduction in allergy symptoms, fewer dust accumulations on furniture, and an overall fresher feeling to the air throughout my house. The difference is noticeable within just days of installation. The electrostatic pleating technology is what sets these filters apart from standard options. The pleated design dramatically increases the surface area available for filtration compared to flat filters, which means better particle capture without restricting airflow through your HVAC system. My heating and cooling system runs just as efficiently with these MERV 13 filters as it did with the basic filters I used previously, which was a concern I had before making the upgrade. The American manufacturing is a quality indicator I genuinely appreciate. These filters are consistently well-constructed with sturdy frames that don't bend or collapse during installation or use. The pleats are evenly spaced and properly secured, and the filters maintain their shape and effectiveness throughout their entire service life. I've used cheaper imported filters that would arrive damaged or fall apart within weeks, but these BNX filters are built to last. The six-pack quantity provides excellent value and convenience. Having multiple filters on hand means I can maintain a regular replacement schedule without needing to remember to reorder constantly. I mark my calendar to change filters every three months, and having the supply ready eliminates any excuse for延迟ing this important maintenance task.

Great value and good product
I have been buying these type of filters for years, and they are efficient, long lasting ( I change them every 3 months whether they need it or not, as they still look good), and they are a good value. I have a cat who naturally sheds kitty glitter everywhere, so the air quality these provide is necessary.

I tried these in my work furnace. I do notice that there is a lot more dust on the furniture than there was with the previous filters. So not the greatest in my book.

I was surprised to see that the filters are encased in cardboard. For these reason I cannot use it as I needed a more solid frame construction and not something that could get damp and warp/mold
