How to shop for Pool filter

Pool filter is an essential device for keeping a pool clean of objects, crystal clear, healthy and at appropriate sanitizing level. It helps not only to remove foreign matter and particles from the pool water but does not allow dangerous bacteria and germs to come in the pool water. These useful devices keep the water from going septic and, therefore, stop swimmers from getting sick. They should be used for both in ground and above ground pools to keep them from algae formation and turning green. This is why it is important to purchase a high-quality filter that will last for long and will keep the pool in optimum condition in every kind of weather and at any season.

There are a variety of pool filters that are available on the market today. They differ by size and depend on the water pool capacity and filtration area. At the same time, all pool filters come in three types: sand filters, cartridge filters and diatomaceous earth (DE) filters.

Sand filters are the most popular and the oldest type out of all the three available filter kinds. They are inexpensive, easy to use and understand. This device cleans the pool water that is pulled into the filter from particles and bacteria through the sand. Filters of this kind are considered to be the least effective type as the water that has passed through the filter and flows back into the pool contains a lot of sand. In addition, the pool filter of this kind becomes full with dirt and grime after a time and it needs a pool pump to flush it out from the water.

Cartridge filters clean the pool water by means of the special filtering material. Filters of this kind are considered to be less expensive than their DE counterparts and they are relatively low-maintenance devices. These filters contain removable cartridges that are easy to clean and replace. Filtering materials can be of different quality. Inexpensive filtering material will need to be replaced frequently while high quality and expensive cartridges will operate for many years without needing replacement.

Diatomaceous earth, or DE filters are the most expensive and the highest quality pool filters. They use crushed fossil or natural substances to clean the pool water. These substances are usually thinner than sand and these filters produce the cleanest water possible. At the same time, these filters need frequent replacement that makes this filter type more expensive in maintenance and fiddly to use.

The best modern pool filter will ensure the cleanest pure pool water, eliminate possibility of diseases caused by pool bacteria and reduce power energy consumption. However, any type of the filters needs regular maintenance and keeping it clean and free from dirt, leaves and hair.
