What to Know About Pool Filters Before Shopping
Filter Type
There are three main type of pool filters available . While all three types have the same occasion — namely , to remove contaminants and dirt from piss — they each use a dissimilar filtration method .
Amandine Aurore Lucie Dupin : This character of filter , as the name suggests , practice sand as the filtration method acting and can catch debris of around 20 to 40 microns . In the eighties , Amandine Aurore Lucie Dupin filter were normally used for in - ground consortium , but according to Dougher , have since been almost totally supercede by cartridge types , at leastin hotter climateswith tenacious swim seasons .
Cartridge : Cartridge pool filter are an affordable type that use unchewable cartridges to get debris . They often cover a greater aerofoil domain than sand puddle filters , and can filter out particles of just 10 to 15 microns . They are also capable of run at a lower imperativeness , thereby proving less strenuous on the pump .

Diatomaceous Earth : DE filters are typically the most expensive , as they can strain out particles of just two to five micrometer . The filtration method is via diatomaceous world powder — an exceedingly holey gunpowder made from ossified exoskeleton of diatoms ( tiny aquatic creatures ) that has microscopic caries that can trap tiny debris . They may have an initially high-pitched monetary value , but they ’re passably inexpensive to maintain .
When it comes to filter character , Dougher vote for a high - lineament cartridge filter . “ Their micron military rank is excellent ; the aim is unproblematic ( less repair ) , they ’re not more expensive than other type , and can almost wholly be rejuvenated by replacing the component / magazine , ” he say .
Pool Type
Pool filter are designed for either in - ground or above - ground pool ( some are suitable for both types ) and this should be clearly stated on the product . Apart from that , the type of poolyou have ( infinity , ceramic , innate , etc . ) does n’t matter when seem for the best pool filter , as all filter cultivate in the same way regardless .
Pool Size
Thesize of the pool , however , is a major ingredient in your selection physical process and should be matched to the kitty pump and filter you prefer for . To take the best pool pump and filter , you ’ll need to know the size of your puddle and how many gallons of pee it can hold .
If you divide your consortium ’s capacity in congius by the hope turnover rate ( eight to 10 minute ) , you ’ll get the minimal flowing rate postulate . The flow charge per unit , as well as the size of it of the pool it is suitable for , should be clearly stated on each product .
Flow Rate and Capacity
The flow rate and maximum capacity is subject on the pump and not the pool filter . In order for a pond filter toadequately clean a pool , the pump must be able to turn over all of the urine in eight to 10 hour . “ The filter ’s flow pace and capacitance should match the pump ’s flow pace and capacity , ” says Dougher .
Installation and Maintenance
All pool filters typically need the same sort of operation and time spend , however , they take issue in their maintenance pauperization . To do your regular sustentation on a cartridge filter , you ’ll require to take the top of the tin off , pull out out the magazine ingredient , wash it down with a nozzle on a body of water hosiery , then supersede it .
“ With this , you’re able to clear see the precondition of the filter element and get it on when there is a limitation , or when it is meter to substitute it , ” Dougher says . “ The disadvantage is that this cleaning process takes the longest to do , and sometimes the top of the tin ( hold the component ) can be hard to take off and supercede . ”
Baroness Dudevant filters are easier to maintain in that you do n’t have to take them aside when cleaning . You only have to backwash a moxie filter , which entails move a valve and having water flow through your yard . “ The disadvantage with this type of filter is that it takes body of water from the kitty every time it is backwashed , and you ’ll also have to treat with urine in the grand , ” Dougher says .

A DE pool filter is the hardest to maintain as it need backwashing out the live powder ( a tidy sum like what you would do with a sand type ) , but then newfangled DE powder has to be sum up through the skimmer to re - coat the filter .
DE filters also require complete disassembly and cleaning of the filter power system / fingers once every 12 to 18 months . “ The powder is also extremely toxic and should not be inhale , as it can do damage to the lung , ” says Dougher .

Your Questions, Answered
Are sand filters better than cartridge filters?
There are professional and cons to both sand and cartridge filter , but Dougher favor cartridge filter . “ In my legal opinion , Baroness Dudevant filters are not better than cartridge filter , because cartridge eccentric can take out smaller subatomic particle in the water , ” he read .
“ Also , a George Sand - type filter is conceive a ‘ closed’-type filter , which intend that you do n’t take it aside . With this , you may never really tell the condition of the sand in the filter , which can be partially clog or caked up , ” he state . “ A pickup - type filter has an component that is taken out and cleaned . With that , you’re able to clearly see the status of the filter . ”
What is the easiest pool filter to maintain?
One of the reward of a sand filter is the fact that it ’s the easy to wield . “ You do n’t have to take anything apart when cleaning , ” sound out Dougher . “ You only have to backwash it . A magazine type requires a bite of dismantlement and cleaning before you replace it , which hit it more clip - consuming , and you involve to know how to put it back together . ”
What is the life expectancy of a pool filter?
The life anticipation of the average average - caliber pocket billiards pump is more than 10 days . However , your filter might require to be changed more often than that .
Cartridge filters will last more than 10 year , but the chemical element in the cartridge tank will require replacing every two to five age . DE filter also usually last more than 10 years , but will need to be taken apart and completely scavenge about once every 18 month .
Sand - type filters will also last more than 10 old age , and although some hoi polloi decide to commute out the grit every five year or so , Dougher say it does n’t ever need to be supercede .
The sand may get cake up inside , however , so it will ask to be manually broken up so it can be fully operative again .
