There is no individual who would like to do swimming in grimy water. You will experience all you need by simply keeping your swimming pool ever clean. But then, how can this be done? By the use of a swimming pool filter, there is no difficulty you will ever encounter in doing pool cleaning. They are responsible for keeping off bacterial and any other kind of dirt that may be in the water keeping you safe always while enjoying the swimming. There are so many pool filter options you can consider to work for your pool. Before deciding on a particular pool filter, there is a number of factors to consider helping you settle for the right one for you.

While in the market to buy a pool filter, you will come across three types of pools, i.e. the diatomaceous earth pool filter, cartilage type and also the sand filters. All you need to know is that there is no pool filter that has been designed to carry out every kind of pool application. Each of them uses a pump to help push water. Let’s first learn more about these pool filters to have a clear guide on choosing the right filter for your pool.

Sand filters

These pool filters are ideal for individuals who might be in tight budgets and don’t need spending too much of their time to maintain up their pools. They are large tanks that have been filled with filter sand like for instance zeolite and #20 silica sand. This is what helps in removing particles that are of sizes as low as 20 microns. In terms of size, these filters are larger than their counterparts the DE and cartilage filters. His provides an idea for those who will never like a filter that can take up much space. To add on this, buyers need to know that these are the least effective kind of filters since the other existing options are capable of handling smaller particles that are of a size as low as 5 microns.

How does this pool filter work? Water from the pool fills 2/3 of the tank and sand in the filter traps any debris as it moves through the filter. How is this debris taken out? This is something someone else would like to know. The dirt is collected and left in the tank till the time the system will be backwashed and then water that has been filtered returns to the pool. You can know that this filter is working at its best if you note the water pressure being strong. If the gauge pressure is strong, the pump basket housing is full of water constantly and also if you notice that the water is clear. Replacement of sand needs to be done at an interval of between 3 to 5 years to ensure proper functioning of the sand pool filter.


  • The pool filter is easily cleaned
  • This is the most affordable pool filter you will find in the market
  • Its large surface area helps to clean more dirt particles.


  • A lot of time is wasted when carrying out regular rinsing and backwashing
  • It is not such efficient as it can’t trap debris less than 20 microns
  • It creates most pressure making it less energy efficient.

Cartridge filters

These are actually the most popular pool filter for residential pools since they tend to be painless of use because of the kind of design they come with that is simple. Most of the models of this type of filter are normally tall and slim, hence, the best option for those who need to save space. They are somehow efficient than their counterparts the sand filters as they are capable of filtering small particles of size down up to 10 microns.

This cartilage has only two parts to its tank, which are the bottom and the lid. The tank houses three to four filters. The filters are made of bonded polyester or papers that have been weaved tightly to carry out their function in trapping any kind of debris. This is the type of pool filter with the most filter surface area as compared to other types in the market all along with its efficient performance even when running at slow speeds and also has less resistance.

Usually, it takes somehow more effort when cleaning this kind of filter than the DE type of filter but also less than that of the sand filter. The other thing you need to note with this filter is that backwashing is not needed with it. In a similar manner you do with replacing sand in the sand filters, for this type of filter, you will need to do cartilage replacement. You need to keep in mind that they are not the best options for those owning large pools as it will require several of them to maintain the pool water clean. or you can use water heater repair device to clean and keep your water hot and safe.


  • These are actually the easiest filters to maintain
  • They are energy efficient since they work well even at slow speeds
  • They are capable of filtering small particles of size as low as 10 microns
  • They don’t require backwashing


  • In terms of cleaning, much effort is required
  • They usually need to be cleaned more often
  • Replacement of cartilage is done at a period of between 2 to 3 years

Diatomaceous earth filters

These are technically the most advanced filters you will find in the market. They work in a similar way as the sand filters but then with a different filter media. This filter has grids covered with fine powder. The grids aid in the movement of water into the filter bottom and then up. They are actually the most efficient filters as they are capable of trapping fine particles of size as low as 3 microns.


  • Capable of filtering particles of as low as 3 microns
  • Known to provide cleanest and safest water than its counterparts
  • It is not difficult in doing recharging and also the cost of the powder isn’t much expensive.


  • Its purchase and maintenance costs are high
  • The powder used is carcinogenic in form, therefore dangerous if inhaled
  • Regular deep cleaning of grids is required.

Choosing a pool filter that will best fit your needs a lot of considerations, this is as from the pool size, time one will be willing to provide into its maintaining, the kind of debris that often enters the water, and how often the pool is used.

For those in need of low maintenance filter, you need to consider a cartilage filter as they are easily monitored and maintained. Sand filters are ideal for larger pools; on the other hand, choose a DE filter for the cleanest possible pool water.
