The
swimming pool filters you choose to clean your pool can have a large
effect on how enjoyable your time in the pool is for you and your
guests.
Filters are actually available in three main options. There is no
right or wrong type of filter that you should buy, but it is important
to try to make sure that you are getting the one that fits your pools
needs.
• Sand filter – Graded sand is used as the medium in
these types of filters. Basically the process is that water is able
to enter into the filter through the diffuser. After this occurs,
the debris and other contaminants are trapped in the grains of sand.
In the meantime, the pool water continues to be able to flow though
the filter.
• Cartridge filter – The cartridge filter uses something
similar to a paper-like cartridge as the filter medium. These filters
are effective because they anywhere from 300-500 square feet of medium
in order to simply be able to make sure that the pool water is filtered.
This allows for only having to clean and replace the cartridge once
every six months or so.
• Diatomaceous earth – This is a different kind of filter,
but equally useful. Basically these kinds of filters use sedimentary
rock to serve as the medium. These DE filters tend to run at a higher
water pressure than most cartridge or sand filters. This may lead
to inefficiency and flow loss inside of the pool if you don’t
have an adequate pump.
Each of these swimming pool filters has advantages and disadvantages.
Your responsibility is to try and figure out which is best for you.
