Pool Filters

The key to a healthy, clean pool starts with your filtration system. Your pool filter’s purpose is to collect fine particles of waste from the pool water, which helps keep the pool water clean and crystal clear. We offer many different filtration systems for both above ground and inground pools.

How sand filters work

Sand filters are the most popular type of pool filter because they are easy to maintain, and are very affordable.

Sand filters use a very fine particle sand called Mystic White Silica Sand to filter dirt and debris out of the pool water. A sand filter will filter particles as small as 20-22 microns!

No chemicals are needed to clean the sand inside the sand filter. When the sand inside the tank becomes dirty, the pressure gauge will rise 6-10 PSI higher than normal running pressure. When this happens, the sand needs to be cleaned or “backwashed”.

How cartridge filters work

Cartridge filters fall in the middle of the road when it comes to price and filtration. When it comes to filtering smaller particles, cartridge filters are superior to sand filters since they can filter particles as small as 10 – 15 microns! Another benefit of cartridge filters is that they are more affordable than D.E. filters.

Cartridge filters have replaceable elements inside that are easily changed. With a cartridge filters you don’t have to handle heavy bags of filter sand or worry about diatomaceous earth (D.E.) needed for D.E. filters.

How D.E. filters work

Although they do require the most maintenance, D.E. filters provide the best form of pool filtration, and clearest water in the industry. They can filter particles as small as 1-3 microns!

Diatomaceous earth (D.E.) filters have elements inside the filter tank that need to be coated by D.E. to filter dirt and debris out of the pool water. To do this, D.E. must be added to the filter system by pouring it into the skimmer basket. The amount of D.E. used will vary based on the filter manufacturer, tank size, and water cleanliness.

When should you replace your pool filter?

No matter what type of pool filter you have, there are some common problems that may require you to replace your pool filter over time, including:

How to clean your sand filter

Backwashing causes the water flow inside the filter to reverse, sending any dirt and debris in the sand out to waste, leaving only the clean sand inside the tank. You will generally have to change the sand inside the filter every 2-3 seasons. Sand filters are great for someone looking for an affordable filtration system that requires minimal maintenance during the swimming season.

How to clean your cartridge filter

With proper care, the replaceable elements used in your cartridge filter can last two seasons. These replaceable elements are easy to clean – simply rinse them from the inside out with a garden hose. If your cartridge filter’s replaceable elements aren’t regularly rinsed then they can become extremely dirty or stained, in which case you may need to use chemicals to clean them.

How to clean D.E. filters

Like sand filters, when the pressure gauge rises 6-10 PSI higher than normal running pressure, the elements need to be cleaned. D.E. Filters are cleaned by either backwashing or regenerating.
To regenerate the D.E. filter you first draining the dirty D.E. (which is removed from the filter and disposed of). When this is done, fresh D.E. will need to be added through the skimmer.
