What is the furnace filter?
The furnace filter is a removable filter that fits somewhere in the furnace between the location of the air supply and the engine, the fan and the heating coil. The furnace filter was originally designed to protect motor and internal components from air and dust particles that can damage the furnace. For this purpose, manufacturers use a standard glass fiber furnace filter. However, the furnace filter can also serve several other purposes. Without a furnace filter, the system would be clogged with dust, which would cause the engine to work harder until it eventually overheats and stops working. Generally speaking, this is the only purpose of the standard furnace filter of glass fibers. These filters are cheap, usually below $ 5 (USD), and require replacement at least every three months to work with efficiency.
Although he originally designed as a way of protecting the mechanical furnace components, the furnace filters have been reworked in recent years because to the forefrontThey discovered concerns about the environment. Today, filters of furnaces are available to improve the quality of internal air, which will replace the standard glass fiber. These modern filters not only protect the engine of the furnace and mechanical part, but also improve the quality of the inner air by capturing dust, pollen, smoke and other internal pollutants by magnetically charged ions. The air circulates with a filter and is blown back through the holes to improve air quality.
How does the quality and power of the furnace filter increase as the price. Most Pec filters are one -off, although some are designed to be washed and reused. When selecting a furnace filter for your home, you must first know about the size of the Takes filter.
For quality selection, there is a system of evaluation called MERV that means the value of the minimum efficiency message . Generally speaking, the higher the MERV rating, the better the furnace filter will be. Regular replacement of the furnace filter can help extend the life of your furnace and improvet its evaluation of effectiveness.
To maintain the furnace system at the same time and improve the quality of the inner air, look for cheaper glass fiber filters. Most Pec filters on the market that retail more than $ 10 is designed to improve air quality to some extent. For households whose members experience allergy or respiratory problems, top, high -performance filters can help change.
