Knoxville, Tennessee swimming pool contractors explain three pool filter styles
When it comes right down to it, a pool filter is one of the most important components in your swimming pool. Why? The pool filter can be considered the heart of the pool because without it your water will become dirty, bacteria and algae filled and you won’t be able to enjoy it.
The pool contractors from Tipton Pools explain that the pool filter is responsible for helping maintain the 
cleanliness of the water by removing debris and dirt and helping circulate the cleaning supplies that have been added to the pool water.
There are three basic types of pool filters from which to choose and the style you ultimately decide upon is based on myriad factors including personal preference, price and ease of use. Here is a breakdown of the three types:
- A sand filter. This uses sand to keep the water clean and to filter out impurities from the water. The water is moved through the filter, debris is captured and the clean water is pushed back into the pool. A sand filter can become costly in the fact that the book needs to be backwashed when the filter is cleaned.
- Cartridge filters use fine “material” aka filters to clean the dirt and debris from the water. The water, again, flows through the filter, impurities are captured and held in the filter and the cleaned water is released back into the pool. These filters are relatively easy to clean.
- A diatomaceous earth filter (DE) is considered the most efficient filter on the market, but it also brings with it the highest price tag. These filters capture the smallest bacterial particles within the DE. Diatomaceous earth is made up of fossilized exoskeleton of diatoms. These filters also require backwashing on occasion.
Spend time with your pool contractor to understand the advantages and disadvantages of the various types of filters.
