Swimming Pool Filters


So what’s up with pool filters these days? Trying to decide which is right for you? Basically there are three types of filters. Sand filters, Cartridge Filters and Diatomaceous
Earth filters, more commonly referred to as “DE Filters”. Each of these filters will work quite well
but they each have their own drawbacks. Sand filters are very common. They will “catch” dirt and debris as small
as 30 microns. These big round domes of sand are easy to
use and allow for quick backwashing, which sends water backwards thru the sand bed and
out to waste which helps give the sand a quick cleaning. Downside is you lose some of your pool water
doing this backwash and will have to replace it. If you live in an area with water limitations
or a weak well, it might not be the best choice. While it’s the slowest filter it can be
tweaked to catch smaller bits of debris if you add a small amount of DE to it. You can find directions for this on the TFP
website. One common myth we’ve heard told is that
you need to “change your pool sand routinely”. Poppycock! That sand has held up a bazillion years before
going into your filter, and will be just as good for years to come assuming you haven’t
gummed it up with various pool store potions. A good cleaning of the sand once in a while
is all it needs. Next up on our filter review is the Cartridge
Filter. They’re good at getting even smaller bits
out of the water than the sand filter- 10 microns.! It’s a good choice for those who want to
limit pool water loss. To clean the filter you take the panels out
and spray them down with a hose. One handy tip is if you oversize your cartridge
filter you can usually go longer between cleanings. You may need to occasionally replace panels
if the fabric gets torn. Lastly, there is the DE Filter. It’s a serious filter, grabbing debris as
small as 3-5 microns! You have to use it with pool specific DE powder,
not the agricultural type. When it needs cleaning it can be a bit more
work than the other types of filter, because it is catching so much more debris. DE filter owners swear that it makes the water
sparkle! Each filter should have a filter pressure
gauge on it. We recommend cleaning the filter once the
internal pressure of the filter – the PSI, raises 25% over your clean filter pressure. If you have questions, come ask them at Trouble
