Mechanical filtration is usually the first step in a multiple-step filtration process. At this stage, sediments, particles and other solid materials are removed from the water to prepare it for the next stages, which are usually chemical or biological filtration. It's important that the unwanted materials are all removed in the mechanical stage so that they won't have to be carried over to the other steps.
There are different kinds of filter media that can be used for mechanical filtration. The two popular choices as filter media are carbon and polyester fiber. The Blue Ribbon Pet Products Polyester Filter Fiber from Pet Store

-- and even pods, too. It can trap in dust and dirt effectively, making it ideal to use as a filter media. Because of the really close and tight cross-section of the fabric of this filter media, even very fine and tiny dirt particles and contaminants get trapped.
The Blue Ribbon Pet Products Polyester Filter Fiber is resistant to heat and fire. It can be used in temperatures as hot as 450 degrees Fahrenheit. Even at this high heat, the media will continue working just fine without any hint of damage or deterioration.
