Even though you may not realize it, many systems in your home that are there for convenience and to make your life easier require some sort of filter for them to function properly. Filters are found in plumbing, irrigation, and cooling & heating applications. When you are using water, a central air system, or a sprinkler system-there is a chance that there is some sort of filter helping that equipment to run correctly.
Drinking water is also filtered as it passes through a refrigerator that has water dispensing capabilities. It also filters the water that is taken into the ice maker so that the ice that is being made doesn’t contain “floaties”. This technology has also been applied to drinking fountains that are found in some public places.
In some irrigation and sprinkler systems, the water comes from wells or other sources where
The air that goes through a central air system, whether it be to warm up or cool down the place where it is installed, needs to be filtered. If the air isn't filtered, harmful debris and some disease causing organisms can be spread to the areas where the air is being dispersed.
In all of these different applications, there are a wide variety of filters available. Some of them are as simple as only filtering out a single particle, while others are designed to remove more than one particle and some chemicals that can be found in air and water. The filters used in different applications are also made of different materials. Some are made out of plastic and soft materials, while others are made from metal so they can withstand more pressure and materials that are considered to be harsh.
