Whether your pool/spa sits outside or under the protective cover of a roof, it still collects dust, debris and other nasty things which can ruin the fun of an afternoon swim or late night soak. Those same nasty items can ruin your health.
In an effort to prevent either of those tragedies, pool and spas come equipped with inline filtration systems designed to remove unwanted items from the water. Several different types of systems are commonly used:
- Sand — Often found on aboveground pools and on commercial pools. Water passes through a body of sand and as it does so, larger particles get filtered out.
- Diatomaceous Earth — Often found on inground pools of all sizes. Cloth covered fins or ‘fingers’ coated in a silt-like, white, material which looks very much like finely ground chalk filter out unwanted solids.
- Cartridge — Often found in spas and on very small aboveground pools. Porous paper sheets filter out unwanted solids.
