The MERV 13 (A, K, A. The best filter) is our top-of-the-line model. It is electrostatically charged and made from materials that are more efficient than standard pleated polycotton filters or fiberglass filters. In fact, it is so effective that it can filter particles smaller than one micron in size.
Recently, recommendations and mandates cite MERV-13 air filters as the starting point for reducing infection risks in public buildings. The filtration industry uses the ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) national testing standards, known as MERV, or Minimum Efficiency Report Value, to measure the efficiency of air filters. Some manufacturers use an electrostatic charge to temporarily increase the MERV value of their air filters. However, this charge dissipates over time, reducing the MERV value of the air filter.
It's important to replace filters regularly because older air filters are less effective at removing bacteria and dirt from the air, which will worsen indoor air quality and increase energy costs. A MERV 13 air filter provides the greatest possible protection without compromising the reliability of the HVAC system fan. If someone needs a clean indoor environment for health reasons, a MERV 13 air filter is the best option. BNX MERV 13 air filters are made with a special electrostatically charged filter medium that can effectively remove up to 95% (3 to 10 microns) of harmful microscopic particles from the air that can aggravate allergies, asthma and other respiratory problems.
We recommend replacing the filter regularly to ensure that the air is kept clean, energy costs are reduced, and that the air conditioner is operating properly. For an even more efficient filter with mini-folds and odor reduction technology, choose the Filter King Titanium – the most efficient Filter King filter on the market. Tobacco smoke particles that stay in the air long after smoking are usually less than a micron tall, making these filters ideal for superior residential and commercial use and for smoking rooms. Considering the threat posed by COVID-19 and other germs, changing a building's air filter to a HEPA is a much more effective step than simply a MERV 13, considering the small size of the virus (0.06 to 0.12 microns); the more efficient the filter, the better. In some buildings with limited capacity to hold deeper air filters due to many smaller units rather than a few larger ones, if there is no applicable mandate but you may be asked to follow guidelines requiring a MERV-13, then it is highly recommended to consider a MERV-9A air filter to achieve a higher level of overall filtration performance over a longer period of time.
