Having your own pool is a glorious feeling but maintaining it requires some effort on your part because above ground pool filters need periodic cleaning.
The pool will not continue to look beautiful no matter how much money you spend to buy one, if you don't take care of it.
Clean pool water is very essential to ensure safe and healthy swimming conditions in your pool.
You need to consider all of the pollutants and contaminants that exist in the air and surroundings that are constantly entering the pool and are harmful to people's health.
A whole host of pollutants in the form of pollen, spores, bacteria, dust, debris from the outside and sweat, body oils, lotions from people inside the water all combine to contaminate the water.
They are an essential part of the pool to remove pollutants, debris and other organic matter.
Keeping the filter in excellent working condition to remove the debris quickly and efficiently is very important.
This is the only way to make sure that your pool water is safe to swim in.
Swimming pool sanitation depends on above ground pool filters.
While pool pumps help to re-circulate the water, the filters help to strain all impurities out of the water.
Above ground pool filters are vital for filtration and cleaning systems in swimming pools.
As the water passes through the filter, all the contaminants and debris get trapped in the filter, which you need to keep constantly keep clean.
When choosing pool filters you need to buy them according to the size of your pool.
The store sales person can help you, so make sure you take along pool specifications when buying above ground pool filters.
Some of the above ground pools come with filters at the time of buying a new pool.
In that case you can make a note of the model number in a safe place.
Mobile phones are good for storing such information.
When choosing above ground pool filters you have a choice of three types: sand filters, diatomaceous earth filters and cartridge filters.
A brief overview of each of these above ground pool filters is in order.
Sand filters: probably the oldest and most widely used of all pool filters.
The water flows from top to bottom through the filter and an under-drain that is situated in the bottom of the filter returns the water to the pool.
When the water filters through, the filter is fitted with slots that prevent the sand from entering the pool.
Debris and other contaminants get trapped in or on top of the sand bed, allowing clean water, free of debris to enter the pool.
The sand used in these above ground pool filters is a special kind known as #20 silica and can be cleaned by reversing the water flow to backwash the filter.
Diatomaceous earth filters provide the best level of filtration; it is a porous powder having microscopic openings that allow water to flow through trapping debris as small as 2 microns, preventing it from flowing back into the pool.
Cartridge above ground pool filters are known to be more effective than sand filters because they cover a larger surface area than sand filters.
They trap small particles effectively and are actually capable of twice as much filtration than sand filters.
