Basic components

  • Good circulation due to their constant speed
  • Long lifespan
  • Popular

  • Consume a great deal of energy because of the same power level
  • Generating loud noise when operating

Dual Speed (Two Speed)

To be more specific, the low mode (1,725 RPMs) is utilized for filtration or essential circulation while the high mode (3,450 RPMS) is set to undertake activities such as operating the pool heater or best robotic pool cleaner for inground pool.

  • Power flexibility
  • More energy saving

I guess some of you might hear their names: Diatomaceous Earth, Sand, and Cartridge pool filters. Keep going on to figure out your right filter based on their characteristics, and strengths.

Diatomaceous Earth (D.E)

Diatomaceous earth is a kind of powder that is obtained from an algae group. These filters consist of a large container which has eight grids covered with D.E powder. Hence, it will catch all water pollutants those are as tiny as approximately 3 microns.


In comparison with other sorts of pool filters, D.E ones are the most expensive that could be up to about $600.

Filtering sensitivity

In fact, this is the outstanding feature of a diatomaceous earth filter. With the ability to catch even 3-micron contaminants, it is currently the highest ranked filter on the market.


Diatomaceous earth filters could work efficiently up to 10 years, but they require regular maintenance


Sand filters are known as the extremely simple designs, which contains a major pipe, and laterals at the bottom beside sand as a filter.

The water will be pulled down and cleaned through a massive amount of sand immediately when it goes into the filter system. All the pollutants will be kept into the sand, and the clean water will be pushed out.


Sand filters are the cheapest pool filters because of their simple design and working method. With $250, you could own a sand filter.

Filtering sensitivity

The smallest size of pollutants that a sand filter could trap is around 40 microns, which is tinier than our hair.


Seven years is the maximum time that sand filters could perform well. The remarkable feature of this filter is that it does not need regular maintenance. All you need to do is replace the sand.


It is true that a cartridge pool filter is a happy combination of a sand and D.E filter. It offers you a good filtering sensitivity, and use less water to operate. Also, cartridge filters are simply designed with four cartridges which have channels to catch the water pollutants.


Although these filters are less expensive than D.E filters, the price is still high ranging from $200 to $600.

Filtering sensitivity

They can filter out pollutants that are as tiny as 15 microns.


Unfortunately, cartridge filters could effectively operate within five years. That is much shorter than two types of pool filters mentioned above.

Overall, if you want to keep your best above ground pools for family water clean as much as possible, you should pick a D.E filter. However, if maintenance is your biggest concern, pick a sand filter. Lastly, if you like a filter that is not too expensive and does not require regular maintenance, choose a cartridge filter.
