How to Find Out the Right Size?

It is important that the pool filter matches and marries with the size of your pool. If they do not reciprocate each other you would have eternal issues with your pool filter. Every pool filter whichever you may select has their limitations and it is imperative that you be prudent in your selection and also that it is the right decision. Pool filters provide details like the quantum of water that they would flow though during a set period of time. For example 57,600 gallons in 8 hours or it could be 72,000 gallons in 10 hours.

This should give you an indication as to which model and brand of pool filter that you would need to select. If your pool is anywhere near these sizes you could select one of the above brands or models to keep your pool clean, clear and healthy. There are different types of pool filters also around from which you could select. That would depend on your preferences and also the availability and other salient factors. Using the right type of filter whether it would be a cartridge, sand or diatomaceous earth would depend which of the three you would like to use in the filtration process of your pool.

Pool filter size matters

When selecting the right size of pool filter the surface area of it would also need to be considered. This is because the filtration process would collect dust and debris on it. If it is bestowed with a surface area that is below average you would need to clean the filter quite often. On the contrary if the filter surface area is expansive your cleaning cycles would be far in-between. If a model boasts that it has a filter surface area of 325 square feet or even 700 square feet that would be something that you would need to consider quite seriously.

This would apprise you of the efficiency of the filtering process. Hence the size of the pool filter for inground pool matters when you would want to select an inground pool filter. Another thumb rule that you could take into consideration would be the rate of the water flow through the pool filter. The Gallons per Minute or GPM would also help you to get a fairly good idea as to what size pool filter that you should buy. But again with three different pool filter types this equation could also change. Hence it would depend on which type you would prefer and the size of your pool.

Compromise needed

In any case it would be prudent to install the pool filter with a slightly higher capacity than your calculations because in effect when it starts operating there could be some anomalies. These cannot be corrected later on especially after installing it. Hence adding a few gallons more or buying one with little extra square feet on the filter surfaces should hold you in good stead. It may not necessarily be a case of what is good for the goose may not always be good for the gander too.

The exact calculations could go haywire and if that would be the final outcome you could be having eternal issues with the pool filter that you have installed. To be somewhat sure of what is the best pool filter for inground pools even if you have some professional inputs various other factors could come into play. Hence it would be better to be safe rather than being sorry later.

Some may not agree that a higher capacity would be needed when you could install the right one so that you may save on some initial investments. On the contrary if you lessen the load on your filter by deciding on a higher capacity you may prudently prolong the life of your inground pool filter rather than ruing after a few months or even a couple of years.

What three main types of pool filters:

The three types of pool filters available today use sand, cartridge and diatomaceous earth in the filtering process.

Sand Pool Filters

The use of Sand is very popular because it could go for about five years, with the filtration process without replacement. Sand is considered cheaper and its prolonged use would not be a strain on the purse unlike other forms of filtrations. Quite a quantum of sand is needed in the filtration process but being a five year turnaround the cost could be absorbed because five years is a very long time compared to the other filtration processes.        

  • Advantages

The cost of sand is much cheaper than using other forms hence there is a very evident cost factor involved. This is quite an important advantage especially when things are not quite well on the economic front. When contemplating of selecting a sand filter for your inground pool it would be prudent to consider some of the issues relevant to the decision.

Using a 30” tank diameter that has about 5,0 square feet of filter surface and would hold anything around 600 to 650 pounds of sand would be ideal. The pool should be just under about 20,000 gallons of water.

This could be used for about five years without any issues and with sand comparatively cheaper you would be settles for a long time without the hassle of replacing 600 plus ponds of sand. The sand would keep your filtration process at optimum levels and going for something slightly higher would be in your better interests.

  • Disadvantages

Replacing 600 plus pounds of sand could be quite a tedious and daunting task which is one factor that could stretch you to the limit. It is the enormity of the task that would be daunting apart from that sand could be a cheaper option in the long run.

Cartridge Pool Filters

The use of cartridge pool filters is quite an easy task. If your filter tank is easily accessible and the cartridge is easily removable for cleaning then it would be an easy task.

  • Advantages

Cleaning the cartridge pool filter when it is full of debris and dust has to be carried studiously if you are to have your filtering system operating at optimum level. A blocked up cartridge would not be a very conducive way to ensure keeping a clear, clean and healthy pool. Depending on the water in your pool the cartridge filter would need to be removed, cleaned up and replaced. The often you could do it would ensure a better cleaned pool at your disposal. The process is hassle free but would need to be attended to quite often but still it is not a very messy affair.

  • Disadvantages

The replacement of cartridge pool filters could be expensive and that too depending on the brand and model of the pool filter that you would install. Hence it would be prudent to apprise yourself as to the cost of cartridge pool filter replacements before you would purchase any brand on pool filter. You may find a pool filter that would be cheaper than others but when it comes to cartridge pool filter replacement it could be an expensive affair.

D.E or Diatomaceous Earth Pool Filters

Diatomaceous Earth or DE is considered the best filtration system and is becoming quite popular in many areas and among many pool owners. DE is a naturally occurring substance and is a good medium for filtration.

  • Advantages

DE filters are very efficient as they would trap particles as small as one micrometer in size which none of the other two above would be able to. It would ensure a very much cleaner, clearer and healthier swimming pool for everyone and the water would be crystal clear too. In comparison to what DE filtration would deliver the cost factor could be equally quantified. It is the best there is today and replacement of the DE is also a long time process.

  • Disadvantages

The issue with DE is that it does too much and because of this it has got into the bad books of some states in the United States where the use of DE for swimming pool filtration has been banned. The reason for this is that the cleaned up DE where all the debris, dust and other particles especially bacteria that are harmful could get into the sewage and cause untold misery to others using those waters though recycled being reused again. This has caused some anxieties and that has been the reason for the ban. There are other salient reasons too which the authorities are still in the nascent stage of finding and reasoning.
