Is a sand or cartridge filter better?
Cartridge filters can screen out twice as much dirt and debris as a sand filter. Its larger filtration area allows the water to progress through the cartridge removing smaller particles. Maintenance is much easier in that there is no need for a back-washing step.
Why are sand filters better for pools?
Pool sand filters use a lot more water than pool filter cartridges when cleaning. The backwashing cycle will use anywhere between 300 to 600 liters of water. This is one big thing that cannot be ignored and, in this category, pool filter cartridges are the clear winner.
Are all sand filters the same?
Every filter does the same thing. The media that it uses to do that job (sand, cartridges, etc.), is really the only difference.
What kind of sand goes under an above ground pool?
Mason sand, sometimes called mortar sand, can normally be found at any sand/gravel yard or masonry supply yard. It is usually measured in yards. It is very fine and should not contain any rocks or pebbles. This will create a very smooth bottom and is the most popular method to use when installing an above ground pool.
Which is the best sand filter for a above ground pool?
SAND FILTERS Sand Filters are generally the most compact and affordable option to filter an in-ground or above ground pool. Sand Filters use specially designed Pool Filter Sand that removes the dirt and debris as water pushes through the media. The cleaned water then flows back into the pool out through the bottom end of the filter.
What’s the difference between a sand and cartridge filter?
A sand filter will only filter down to 20 microns while a cartridge filter will filter down to 10 microns, half the amount. This means that a cartridge filter system will be able to rid your pool of more particles (dirt and debris) leaving it cleaner and more sparkling.
How long does a sand filter last in a pool?
As water flows into the filter it passes through the sand. The dirt and other particles become trapped in the sand allowing clean filtered water to return back into the pool. Sand filters remove particles as small as 20 microns. The filter sand can last 5-10 years between changes giving you a very economical filtration system.
What happens when you backwash a sand filter?
As particles become trapped in the sand it restricts the water from flowing back to the pool. Your pressure gauge will start to increase as the filter sand clogs up with dirt and debris. This is your signal to perform a backwash. Backwashing will send out the dirty water through another port on the valve usually labeled “waste”.

What’s the difference between sand and water filters?
Water filters through these slotted pipes, and then goes up the center pipe to be returned to the pool. Sand filters are capable of filtering particles about 20-40 microns in size, which technically makes them the least effective among the three pool filter types in terms of the particle size removed.
How big of a sand filter do you need?
If you have had a sand filter for a while, you are most likely already aware that the standard filter media to use is called #20 silica sand. This sand is about .45-.55mm in size and is capable of filtering out debris about 20-40 microns in diameter. As a reference, the diameter of the average human hair is 60-80 microns.
