MERV (Minimum Efficiency Reporting Value)is a standard used to measure the efficiency of air filters. This value was developed by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) to evaluate a filter's ability to capture particles of different sizes.

Operating environment: Maximum temperature of 60℃ for continuous useMaximum humidity at the moment of use: 100%RH(unclean dew)Application: General application in central air conditioning and central ventilation system, gas turbine and air compressor prefiltrationAir conditioning filter screen provid

What is HVAC?An acronym for Heating, Ventilation and Air Conditioning, HVAC refers to systems in a home or building that produce safe, clean and comfortable air within a space.•Heating: The "H" in HVAC stands for heating, and as one might guess, this system heats the air in your home. Generally, thi

An HVAC filter is a filter used in heating, ventilation and air conditioning systems. Filters improve efficiency and longevity by protecting HVAC systems from dust and air particulates. Therefore, it is an integral part of the system, but often overlooked. In addition to protecting HVAC systems from
