Best Swimming Pool Filter For Your Needs

by Pool Builders on 12-19-2008 in Articles

In order for you to choose the best type of swimming pool filter for your needs, you will firstly have to know what types of pool filters are available. The three most common types of swimming pool filters are Cartridge, Sand and Diatomaceous Earth Filters (DE filters).

Cartridge Filters

Cartridge pool filters operate using paper to filter debris out of the water. As the name suggests, paper cartridges are installed inside the filter housing. Cartridge filters are easy to maintain and can be cleaned by simply removing the filter medium spraying the filter paltes using a hosepipe. Properly cared for cartridge filters could last for three to five years. To insure you get maximum use out of your filter, make sure you follow a strict maintenance routine. Occasionally the paper cartridge filter plates will require replacement. The filter cartridge prices can range from moderate to expensive.
 
Sand Filters
 
Sand Pool Filters are the most commonly used in residential pools. They work by filtering the water though silica sand which captures the debris from the swimming pool water. Sand filters are considered to be the least efficient at cleaning the water and require more maintenance than cartridge filters. Although the sand in the filter only needs to be replaced every two to six years, maintaining sand filters can be time consuming. Backwashes are an essential part of sand filter pool maintenance as the force of the outgoing water helps to flush out the filtration sand.
 
Diatomaceous Earth Filters (DE Filters)

Diatomaceous Earth Pool Filters are also known as DE Filters. DE filters use diatomaceous earth to clean the swimming pool water. The diatomaceous earth is purchased in a powder form and then added to the filter or directly into the pool when required. Diatomaceous earth powder is a pre-mixed compound and should be used by mixing it with water and slowly add the mixture into the pool. Most DE filter owners add the mixture to the pool by pouring it through the skimmer. This helps the mixture to be evenly delivered throughout the pool as the currents from the skimmer transport the mixture. Make sure the filter is on so the mixture can circulate around the entire pool. The filter grids act as the filter medium and they are the basis of the DE filter. This type of pool filtering method is actually using biological filtration to clean the pools water. DE filter grids can be cleaned by pressure cleaner or by soaking them in water. DE Filters are an efficient and natural method of filtering swimming pool water.
 
Conclusion

The type of pool filtration system that you require will depend on the type of swimming pool and the size of your pool. The most common type of swimming pool filter is cartridge filters as they are efficient and cost effective when compared to DE and sand filters. If you are looking for a natural method then a diatomaceous earth filter will be suit your needs.  Other matters that could influence your filter choice will be the pools location and the amount of dirt that actually falls into the pool. Purchasing a pool filter is the first step, but to ensure that the filter operates at optimal level it will require occasional filter/pump maintenance. Owning and enjoying the benefits of a swimming pool can be fun and rewarding. Take the time to purchase the right swimming pool filter for your needs as it will pay off in the long run.
