The 3 Best Pool Sand Filters To Buy in 2019- Pro’s & Con’s

Introduction to the Pool Sand Filter

Swimming should be an enjoyable experience. Every time you look at your swimming pool or go inside it, you need to be happy and feel motivated to stay in the water, but this is not as easy as it sounds. Maintaining a swimming pool is a quite a hard task but you have to do it otherwise your swimming pool will become too gross to look at leaving alone swimming in. At the core of keeping your swimming pool clean are pool filters. These instruments are essential as they help in getting rid of all the contamination be it from the wind, the materials around/on the pool or even the individuals swimming in it.

There are dozens of pool filters in the market which is a great thing as they come in all shapes, sizes and price tags meaning everyone can afford them. It is also important to note that there are different types of pool filters including sand, cartridge, and D.E filters. In this particular review, we will be looking at sand filters, and we will also go as far as telling you the best pool sand filters in the market at the moment. Before all that, let’s first have a look at how sand filters work and how/whether they are better than the other two.

For everyone who doesn’t have a lot of time or money to spend on maintaining their swimming pools, sand filters are usually the most recommended. These filters are highly effective and quite affordable compared to the other two types of filters, and that is why they are the most commonly used. Sand filters are also ideal for individuals with in-ground pools.

As the name suggests, pool sand filters usually contain a large bed of sand through which the particles coming from the pump are trapped and filtered out. These filters look like a big ball that measures 2 to four feet in diameter. This system can filter up to 20 microns particles meaning that it won’t let any large particles go through. Unfortunately, this pool sand filter won’t be able to prevent the small fine particles from passing through. Once the water has passed through the sand bed and left the impurities behind, it will go out using the drain pipe found at the bottom of the filter.

Sand filters are also quite popular because they are easy to maintain. Cleaning these filters involves backwashing the sand bed to remove all the trapped dirt and debris. Additionally, the sand used in these filters is usually sufficient and will remain useful for up to 7 years before you are forced to replace it. As you can see, therefore, acquiring these filters is not very costly and maintaining them is even more affordable.

Pros of Sand Filters

  • At an average price of $250 for above-ground filters and $750 for in-ground filters, sand filters are, perhaps, the most affordable pool filters in the market
  • Maintaining the filters is a simple matter of backwashing and rinsing
  • The sand used in filtering dirt and debris is easy to acquire, and it also lasts for many years (up to 7 years)


  • They only trap up to 20 microns, and hence these filters will still allow some impurities to get through
  • The more you use the filter or, the dirtier the pool, the more the pressure is required for filtering. This is because the sand bed gets filled with debris thus making it even harder to filter incoming water
  • A lot of water will be wasted when backwashing and rinsing it
