What Is a Filter?

It is a device that is typically used to take out or remove unwanted particles or material from either a gas or liquid solution. It can also be used to limit the amount of material moving through a system. Understanding how they work will help you choose the right replacement filter.

In a filter system the liquid or gas goes through the filter where particles are trapped so the substance can flow through the rest of the system with ease. There is a long list of filters for the home. Some filtration systems it will œload up. This is when the particles get caught in the filter "media" and then as these trapped particles start to build up it makes it easier to stop the smaller particles from falling through. Another system is called the multi-stage system. The majority of replacement filters fall under this category. This is when a pre-filter stops the large particles and the main one stops the smaller particles. Having the two filter systems will extend the life of your filter. Both systems work well in either the home or the business.
