To keep your swimming pool water sparkling and clean you need the
correct balance of at least three separate elements. The
in your swimming pool, the circulation systems controlled by your
Swimming Pool Pump,
and the filtration system controlled by your filter of choice.
Aqua-pool-warehouse offers complete and efficient solutions for great
water quality that your swimming pool deserves. The preference among the
filter types varies by different regions of the country, and by the
suitability for the particular pool. We would like to mention that
a pool can be properly maintained with any of the filter systems
described and that the suitability of a filter to a pool may be more related to the size of the filter rather than
the type of the filter. A grain of table salt is about 90 microns and
the human eye cannot see anything less than 35 microns. The size of the filter itself will matter more
than its type or even its manufacturer. The larger the filter, the
better the filtration system for your swimming pool. We offer only the
best brands with tested and industry leading products and all the
main types of filters in the market. Most filters are stocked in our own
warehouse for quick and efficient delivery.
Sand Pool Filter
Sand Pool filters are the most common types of filters used in the pool industry. They are
the accepted standard in commercial applications or large pool facilities
and is an effective economic solution for your pool filtrations needs.
Sand Filters use especially created sand as the filtration medium and water is pushed through
the medium. The dirt particles get trapped between the sand where the sharp edges of the sand catch the dirt.
On comparison with the other filter types, sand filters usually remove particles
only as small as 20 to 25 microns. Sand filters are the least effective
method in terms of particle size. As the filter sand gets clogged with
debris, it becomes more efficient and catches more dirt but pressure
also increases and the water flow drops. Thus it must be cleaned and
repacked by backwashing the sand.
Backwashing is a process where you run the filter in
reverse through the use of a valve and flush out the dirt. The frequency
of the backwashing is directly proportional to the size of the filter in
respect to the pool. Backwashed water is usually wasted water and this
is another drawback of maintaining a sand pool filter. If the sand gets
too dirty the sand medium can be replaced easily and inexpensively. Sand
filters are are super reliable, inexpensive and has been around the
Cartridge Pool Filter
Cartridge pool filters utilizes a cartridge as the filtration
medium. Usually very popular for most spas and many smaller above ground
pools, the cartridge filter is rapidly gaining popularity among in ground
pool users as well. Cartridge filters use cartridges made of synthetic
filter materials. Cartridges don't clog up as quickly and usually have more available area to
filter. This allows cartridge filters to not reduce water flow like
Sand and DE filters. Cartridge filters put less back-pressure on the pump and hence you get more flow and turnover for an equivalent pump size.
Another advantage is that cartridge filters require little maintenance.
Most often cartridges simply need to be rinsed off and eventually
replaced. Cartridge filters are considered to be between sand and DE
filters and can filter out particles as small as 10 microns. The use of
a clarifier can greatly help cartridge filter perform efficiently. A
great choice where water is a considerable expense
DE Pool Filter
DE filters can take out particles as small as 3 to 5 microns.
Diatomaceous earth are fossilized exoskeletons of tiny diatoms. They are
used to coats grids that are used in the filter to house the DE material
and so filter out debris. Diatom filter area is sized between sand and
cartridge filters. The pressure will still build up as in sand filters
and so DE filters require backwashing usually through the use of a
valve. A multiport valve usually works wonderfully for backwashing
purposes. No other filter type comes close to the performance of a DE
