Pleated filter 10 inch standard (Diameter 2,5″) also called surface filters, are thin filters that catch sediment particles on their surface. These filters are made with a wide surface area that can hold a large amount of sediment particles.

Pleated filters are typically used until their outer surface is completely covered in particles. Afterwards its then disposed of, but some high-end pleated filters can be reused.

These filters work best when dealing with uniform-size particles. If all the particles are roughly 5 microns in size. Also 5-micron pleated filter will work effectively and last a long time due to its wide surface area.

If the particles vary in size, smaller particles will slip through the filter and larger particles will quickly eat up surface area.

So for that reason make sure you have a sediment problem before choosing to use one of these filters. When you decide on what rating to go with. There are two factors to keep in mind for sediment filters. The micron number and whether the filter is nominal or absolute.

The micron number shows the smallest sediment particle the filter can trap. 1-micron filters can catch the smallest of particles. While 20- or 50-micron filters only catch the largest sediment particles.

Nominal filters catch about 85% of particles that are the size of their micron rating or larger, while absolute filters catch 99.9% of those particles. The rating you choose to use is up to personal preference; it all depends on what kind of particles are present in the water.

Filters that are excessively tight can lower water pressure, so it’s best to experiment a little to see which type is right for you.
