Best Sand Filters Buying Guide

Sand filters are part of the purifier and therefore, do not work alone. They are more expensive than cartridge ones; however, they require less maintenance, and for this reason, they are an excellent long-term choice. To choose the best sand filter, you will need to calculate the volume and flow of water.

You have to take into consideration that the purification process is long: typically, a complete cycle lasts 8 hours. Once you have calculated the volume and water flow of your swimming pool, choose a filter with a larger capacity, so as not to find

The filter is made in total accordance with CE / RoHS standards and is mounted on a resistant plastic base. Designed to clean swimming pool water, it can filter the dirt present in it, such as algae, insects and much more.

Few reviews are available. However, they are all very positive. Although it is not considered 100% professional, the pump works very well and excellently does its job with an excellent result. It is also appreciated as it cleans the pool.

What Is a Sand Filter?

Sand filters are the most used elements for the filtration of water with low or medium loads of contaminated items, which require retention of particles up to twenty microns in size. The particles found in the water are retained during their passage through the sand filter.

Once the filter has absorbed the impurities, it can be restarted by washing it against the current. The quality of the filtering depends on various parameters: the shape of the filter, at what height the filter bed is located, the characteristics and the particle size of the filtering mass or the speed at which it filters.

What Is the Swimming Pool Water Cycle?

What we call “cycle” is the passage of all the water in the pool through the filter. The duration of this process changes according to several factors: the size of the swimming pool (therefore, based on the quantity of water), the power of the pump and the capacity of the filter itself during the process.

When choosing the maintenance components for our swimming pool, all these factors must be taken into account, so that the duration of a complete cycle is not excessive. Usually, it takes 8 hours for a residential pool.

How Do Sand Filters Work?

Sand filters clean the water they process from impurities: in this way, the water gets rid of microbes. The water arrives at the purifier through pipes and, once filtered, it is sent back to the pool thanks to a pump that makes the whole mechanism work.

Sand filters work in a closed circuit. The water enters the ducts located on the side, and the bottom then passes through the sand filter, where the particles remain trapped by the silica crystals: the water then comes out clean. Once cleaned, there will be no hygiene problems.

What Types of Pool Filters Are There?

Sand filters are the most used in swimming pool cleaners. In this article, we have focused on them; however, there are also other types of filters and purifiers that you need to know well to make sure you choose the best model. Here is a table with the various types of filters on the market:

What Type of Sand Filter Do I Need Based on The Size of My Pool?

Having a removable pool is not like having a fixed one. Demountable pools usually have less water capacity, and for this, it is better to look for the easiest to maintain filter system: sand or cartridge filters. Both are easy to assemble and usually have silent motors.

If you are looking for a filter for a large swimming pool, perhaps familiar to several people, the sand filter is the most suitable. If you have your private pool at home and want to have clean water every day, the best option is always the sand filter, because it requires little maintenance.

Which Sand Is Used for Filters?

Sand filters use special silica sand, specially produced for them. It is a material highly resistant to chemical corrosion, tough and which does not dissolve in water. Therefore, all these features make it an ideal component for filtering and cleaning swimming pool water.

How Long Should I Keep the Filter in The Swimming Pool?

The power of the filters you are going to install is measured in m3 / h or the equivalent in litres. As you know, 1m3 equals 1000 litres of water. For this, a pump with a flow of 8m3 / h will be able to filter water and circulate up to 8000 litres of water per hour. You need to calculate the volume and divide it by the flow.

In this way, a swimming pool of 8 × 4 meters, with a depth of 1.5 meters, will have a total capacity of 48000 litres. If your pump has a flow of 10m3 / h, it will take 4.8 hours to clean the pool thoroughly. If the capacity increases, you will need a shoe with a higher power.
