Which Pool Filter is Right For You?
Introduction to filtration systems and filtration media.
Pool filters are a must-have for your pool system, but choosing a new filter can be quite difficult. The criteria for the right pool filter is dependent on your pool size, usage and location. With only a few types of filters out on the market, picking the right filter can still be difficult.
Pool filters filter out bacteria and other contaminants that are almost invisible to the naked eye. To put this into perspective, a household dust particle measures at 4 microns, with some bacteria measuring to 2 microns. Although chlorine and other sanitisers work in your pool to kill the bacteria, the pool filter is what actually removes them from the water.
There are two different types of pool filters, let’s have a look at how they vary:
Sand filters work by ‘scrubbing’ water that is pushed from the pool pump. As sand has sharp, jagged edges; the scrubbing captures the dirt or debris, leaving you with crystal-clear water. Sand filters are ideal for medium to large pool owners as they are easy to maintain and less likely to clog. Depending on your pool system as well as your pool size, we have a variety of sand filters that can cater to your needs.
Filter Media Alternatives
The standard media used in sand filters is #20 silica sand, as it can grab particles that measure 20 microns or larger. As it cannot capture the smaller particles, you’ll need to stay on top of your pool water chemistry. There are other sand alternatives to the #20 silica standard that you might feel are best for your needs:
Cartridge Filters are typically more expensive than sand filters, although they are still easy to clean and effective for medium to small pools. It works by the water flowing into the tank and through a plastic cylinder surrounded by pleated polyester filter media and capped on each end. The debris; as small as 10 microns, is captured in this filter, and the clean water flows through to the pool.
The cartridges are energy efficient and inexpensive but will require cleaning by removing them from the tank and spraying them with a hose to remove the debris and dirt.
Picking a filter will ultimately depend on your lifestyle, budget and pool size. We hope it helps a bit with the different types of filters that are out there. If there is anything further you need, speak to your local AstralPool dealer.
