Review: Good quality with reasonable cost - This is a high-quality air filter with reasonable cost that really prevents all types of dust in my household. I have consistently renewed my purchase of this product each year.
Review: 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.

## Questions & Answers

**Q: What is the best air filter for my home?**
A: The best air filter depends on size or dimensions, filtration rating (MERV, MPR, FPR), and quality your AC unit requires. Our filters capture up to 98% of microscopic airborne particles (3-10 um) with industry leading low pressure drop.

**Q: How do I replace my air filter?**
A: Confirm the size of your air filter. Remove plastic wrapping on your new filter and locate the arrows to indicate the direction of air flow. Open your air vent cover, insert the new filter with the arrows facing correctly, then shut air vent cover.

**Q: What does MERV mean in air filters?**
A: MERV stands for Minimum Efficiency Reporting Values which reports a filter's ability to capture microscopic particles ranging from 0.3 and 10 microns (µm). The higher the MERV level, the more efficient it is at filtering microscopic particles.

**Q: What is the difference between Nominal Size and Actual Size of Air Filters?**
A: The nominal size is a rounded number to the nearest whole or half inch, (ex: 20 x 20 x 1). The Actual Size is the exact measurement that shows the filter's actual dimensions (ex: 19.75 x 19.75 x .75). All Air Filters display both sizes.

**Q: What quantity of air filters should I buy?**
A: This is dependent on each customers unique air filter requirements. Our selection includes pack sizes that range from 1 to 12 filters. Each filter last up to 3 months depending on various aerosol conditions such as, dust, smoke, and pets.
