In theory, this type of air filter can remove at least 99.97% of dust, pollen, mold, bacteria, and any airborne particulate matter with a size of 0.3 microns (µm).
Air filters
are essential for our indoor environment. They protect the occupants and equipment of a building from the effects of poor indoor air quality, dust, particles, and contaminants. Moreover, they protect your air conditioning system from unnecessary maintenance and malfunctions.Installing inefficient air filters can result in wasted energy, additional maintenance costs, damaged equipment, and unproductive workers. There are many types of air filters on the market, but the most cost-effective isn't always the cheapest. Many people only consider the starting price as a factor when buying an air filter, but the real cost is the long-term cost of using an air filter. Here's a look at some of the most common high-efficiency air filters, their benefits and applications.
High efficiency air filters are designed to capture particles that are much smaller than those captured by standard filters. This means that they can remove more dust, pollen, mold spores, bacteria, and other airborne particulate matter from the air. They also reduce system energy consumption and don't need to be replaced as often as cheaper filters. While they may be more expensive initially, they save you money in the long run.
The most common type of high efficiency air filter is the HEPA filter. HEPA stands for High Efficiency Particulate Air and is a type of filter that is designed to capture particles that are 0.3 microns or larger in size. This type of filter is used in many commercial and industrial applications such as hospitals, laboratories, and clean rooms. It is also used in residential air conditioning systems to improve indoor air quality.
Another type of high efficiency air filter is the vacuum filter. These filters are designed to capture very small particles such as dust mites and other allergens. Vacuum filters are usually marketed as HEPA-type filters but do not have the same filtration efficiency as true HEPA filters. To ensure that a HEPA filter works efficiently, it must be inspected and changed at least every six months in commercial environments.
In residential environments, depending on the overall quality of the ambient air, these filters can be changed every two to three years. The F200 Media air filter from Honeywell is up to 97% more efficient at removing airborne particulates than a standard one-inch air filter and maintains high airflow in the heating and cooling system to operate at maximum efficiency. Finally, there is a method for determining the efficiency of a filter based on the size of the particles called high pressure drop testing. This test measures the resistance to airflow when exposed to particles of a known size in an air stream.
A high pressure drop means that there is greater resistance to airflow so the air pressure on the outlet side of the filter is considerably lower than on the inlet side. High efficiency air filters offer many advantages including improved indoor air quality, reduced energy consumption, and lower maintenance costs. They are an important part of any home or business's HVAC system and should be inspected and changed regularly for optimal performance.
