You may never have thought about it, but it’s a key decision for the future of your pool. The filter you choose for your pool is very important, as the water quality depends on it. The operation of a pool filter or purifier is quite simple, going through three phases.
-
Suction. At the beginning of the process, the water is drawn in by the skimmer and transported to the tank.
-
Filtration. The water passes through the filter where impurities are separated.
-
Return. Clean water is returned to the pool.
There are several types on the market, and below we will see the main ones:
– Sand filters. The tank of this type of filter or purifier is made of silica sand, which filters the water. They are a favorite for many because they require almost no maintenance, and the filter can last up to 7 years, although it is advisable to change it every 4 or 5 years. Currently, in addition to silica sand, other media are also used, such as activated glass, which we have discussed previously.
– Cartridge filters. This type of filter requires more maintenance since it uses replaceable filters, which last between 6 and 12 months and must be cleaned at least once a week to remain effective. They tend to lose filtering power over time. They are considered the ideal filter for polyester and/or above-ground pools.
– Diatomaceous earth filters. Composed of fossilized microscopic organisms that filter water. They are capable of trapping even the tiniest particles of dirt with great efficiency. They even remove oils and sunscreens. They are the most effective and recommended for large swimming pools.
For greater efficiency and better maintenance of larger, more expensive filters, there are air blower pumps for filter backwashing. These will extend the life of your filter and ensure optimal performance.
Now you know about the main types of filters available. Consider your pool’s characteristics and your preferences, and choose the one that’s right for you. Have questions and need our help? Come visit us or contact us for a free consultation.
