What is sediment?

Frequently Asked Water Filter Questions AnsweredOne simple definition of sediment is matter suspended in a liquid that will (given time) settle to the bottom. It is naturally occurring material that is broken down by weathering and erosion, and then transported elsewhere by various forces–in our case, water. It ranges from very fine silt through sand and dirt, and includes gravel, stones and even large boulders. You may have any combination of types of sediment, but it is usually determined by the speed of the water in which it is transported. Common particles suspended in drinking water include sand, dirt, rust, loose scale, clay or organic material such as decomposing vegetation.

Sediment is a frequent problem in the drinking water supply.

Sediment can damage plumbing and appliances over time. For example, rust particles can cause brown, yellow or orange spots on clothing, fixtures and toilets. Scale can build up in hot water heaters and washing machines, reducing flow rate and shortening appliance life. Sediment can also negatively impact the taste and quality of your drinking water.

WaterFilters.NET offers a wide range of sediment filters to meet your specific needs based on water quality in your area. To filter sediment effectively, be sure to choose a water filter housing that is adequately sized. A larger housing is consistently a better selection. Flow rates will be better, pressure loss will be less, time between cartridge replacements will be longer, and overall water filter cost will be lower per square inch. For whole house applications, do not use the 5″ x 2.5″ or the 10″ x 2.5″ water filter housings; they are designed only for smaller applications like recreational vehicles or  “point of use” drinking water systems designed to supply a single faucet.

Here are some examples of water filter housings big enough for whole house sediment filtration: 20″ x 4.5″, 10″ x 4.5″ and 20″ x 2.5″. For untreated water (like private wells), consider a sediment filter with the common five micron rating: 20″ x 4.5″ spun polypropylene water filter and 10″ x 4.5″ string wound polypropylene water filter. For better flow and lower pressure loss, select a pleated polyester sediment water filter. The pleats give the filter more surface area than a poly string wound or poly spun water filter.

For treated (city) water you could use any of the filter types already mentioned, but you could also consider pleated cellulose, like a 20″ x 2.5″ pleated cellulose water filter. Pleated cellulose water filters are generally the most economical and effective choice for treated water. For certain situations with larger sediment  particles over 75 microns, there are also RUSCO water filters. RUSCO filters are not typically used as whole house sediment filters, but are commonly used to filter irrigation water to protect sprinkler heads from clogging. RUSCO’s most popular feature is reusability, but they are not designed for sediment smaller than 75 microns.
