Filters for Above Ground Pools
One of the most important aspects of owning an above ground pool is to find the appropriate filtrations system suitable for your needs. Taking the time to determine which filter is best for you and your pool will pay off in the long run. Stick with quality brands to prevent premature mechanical issues and possible safety issues. There are 3 main criteria to consider when purchasing a filter for your above ground pool. This criteria includes pool size (is your pool small, medium or fairly large?), filter type (would you rather have a sand filter or one that uses cartridges?) and cleaner type (robotic, suction or pressure side?)

The first thing you will need to do is determine the correct size that will work with your particular above ground pool. Above ground pool pumps range anywhere from ½ HP to 1 ½ HP. Keep in mind that if you purchase a filter will too much horsepower you will end up having too much water movement. Even worse, you could potentially overflow your pool! To determine how much horsepower your pool will need you simply need to take a look at the size of your pool. A fairly small above ground pool will need a smaller filter, a large pool with of course need a larger filter. Manufacturers have specified pool filters based on size. In general, a 1HP filter is enough to clean the water of an average size above ground pool.
Once you have figured out how much horsepower your pool filter will need its time to decide which type of filter you would like for your above ground pool. The two main types of filters are those that use sand and those that use cartridges. This is a purely personal decision.

So now you have decided which filter you need, but what about the cleaners? The three main cleaners (suction side, robotic and pressure side) all have their own pros and cons. Suction side cleaners are less expensive and one of the most common. You attach suction side cleaners to the plumbing system. Keep in mind that they can not handle large debris or a lot of debris in general. Pressure side cleaners are built to capture debris themselves rather than go through the plumbing. These cleaners are also ideal to distribute chemicals. Robotic cleaners are completely independent of any of the pool’s plumbing as well as the filter. Robotic cleaners collect all of the debris and excess material in your pool within a bag.
