HOW TO CLEAN A POOL FILTER
The filter in your swimming pool captures and removes dirt and debris, hair, dead bugs. It even skims out finer particles like bacteria, sunscreen, and body oils. Over time, the folds in the filter become clogged, which prevents water from flowing through easily and increases pressure within the filter. The higher the pressure, the less water volume your pump is going to be able to move because it's working harder. The harder your pump has to work, the shorter its life will be.
On top of keeping the pool water clean, the filter also makes sure pool chemicals are distributed evenly. Your hard-working filter needs the same attention you give the rest of your pool to help it run longer and more efficiently. This will, in turn, save you money, energy and time.
There are three types of filter systems: D.E. (diatomaceous earth), sand, and cartridge. D.E. filters are the most efficient, as they can trap particles as small as 3-5 microns. To put that in perspective, the smallest the naked eye can see is 35 microns.
Many DIY folks turn to trisodium phosphate (TSP) and muriatic acid to clean their pool filters. Both TSP and muriatic acid are toxic and require you to wear protective rubber gloves, goggles and a mask when cleaning.
Simple Green All-Purpose Cleaner is aggressive on heavy soils and greasy residue, but gentle enough to clean filters without harming the material. The biodegradable* formula won't leave behind harmful residue to circulate into your pool water.
It's best to clean your filter once a month during summer and every other month in the winter (if you're still running your pool).
Although cleaning with Simple Green does not require you to wear gloves, you may want to here so you don't contact whatever your filter may have sucked up.
Don't worry if you see a small amount of loose suds across the top of your pool for the next day or so - this is safe for swimmers and it will dissipate.
