Air filters are essential for maintaining a healthy indoor environment, protecting occupants and building equipment from the effects of poor air quality, dust, particles and pollutants. While there are many types of air filters on the market, the most cost-effective one is not always the cheapest. High-efficiency air filters are more expensive but offer several beneficial features, such as reduced system energy consumption and less frequent replacements. The Aprilaire Media air purifier is a quiet, economical and low-maintenance air filtration system that uses a simple and extraordinarily effective HEPA-type filter medium.
It can capture particles as small as one micron with 95% efficiency and particles larger than five microns with 99% efficiency. Sentry Air Systems manufactures custom HEPA filters designed to fit your application and filtration equipment according to size specifications, efficiency and joint placement. Honeywell's F200 Media air filter is up to 97% more efficient at removing particles in the air than a standard one-inch air filter. It also maintains a high airflow in the heating and cooling system to operate at full efficiency.
An ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) filter refers to a fibrous filter that is up to 95% efficient on particles as small as 0.5 microns. MERV stands for Minimum Efficiency Reporting Value and is a measure of a filter's effectiveness in trapping and retaining particles. When choosing air filters to place in your oven, air conditioner or heat pump, pay special attention to their efficiency ratings. This is a method for establishing the efficiency of a filter based on particle size and is determined by testing the filter's performance when exposed to particles of a known size in the air stream. Installing high-efficiency air filters can save you energy in the form of wasted energy, additional maintenance costs, damaged equipment and unproductive workers.
They don't need to be replaced as often as cheaper filters, making them more cost-effective in the long run. Cleaner indoor air creates a more comfortable work environment for your employees and a better shopping experience for your customers.
