What Are The Different Types Of Pool Filters Available
A pool filter is essential equipment of a swimming pool which ensures that the water in your swimming pool stays clean and is at a right hygiene level. There are three main types of filters where you can choose one by the cost, efficiency and other factors. No matter which pool filter you want, every filter does the primary task of filtering the water in your swimming pool. All the three filters have their own way of filtering the water. As an essential part of a swimming pool, what does a pool filter do? So, let us see what the job of a pool filter is?
Why a pool filter?
Three different pool filters and each one quite significant, why? When the water passes through the pool filter, it traps all the large debris and dirt in it. The water in your swimming pool will in cleaned in this way. The cleaned water goes back to the swimming pool through an outlet pipe. Now, let’s move on to the three types of swimming pools. First comes the sand pool filter!
The sand pool filter
The sand pool filter is the most common type of pool filter, and it is the least expensive filter in the market. Most of the older pool systems would have these types of pool filters. The amount of sand in a sand filter depends upon the size of the tank in the sand filter where a filter with a smaller tank will have a small amount of sand and a filter with a larger tank vice versa. You can’t use just any type of sand because there is a specified type of sand which you can use.
The water gets filtered by moving through the top of the sand filter to the bottom of the sand filter. Dirt and debris will get collected in the sand filter, and they remain in the tank till you backwash the entire system. A sand filter performs a few numbers of functions. When the water is getting filtered the filter on the filter mode. If you want to backwash the filter, then you can set it on the backwash mode. You can remove the dirt and debris from the filter will get removed by backwashing the filter.
Back washing is the vice versa of water filtering. Water flows from bottom to top and removes the debris and dirt collected in the filter. The sand will have to be replaced in every three to five years. Replacing can depend on the usage of the pool and maintenance. If the sand is not replaced in the specified time, the pool filtration would not be adequate. Now let us go through the second type of pool filter.
The Diatomaceous earth filter
This functions more like a sand filter, but the one big difference is the filter media used in the Diatomaceous earth filter. You get Diatomaceous earth powder coated grids inside the DE filter. The DE filter can trap lower level microns so that the water will get well cleaned. You can backwash the DE filter too, but when you backwash a DE filter a significant amount of Diatomaceous earth powder will get washed off. Therefore you must add DE powder after the backwashing so the filter will function well. Diatomaceous earth is considered as has harmful to the environment so be careful when backwashing your filter.
It is true that the DE filter is the best of all three types of filters, but still, it gives a lot of trouble in maintenance than the other two. Better give some thought before purchasing a DE filter. After all, the best comes with a few flaws too. Now, let us move on to the cartridge filter.
The cartridge filter
Now, here we come to the last type of filter. Cartridge filters come with a vast variety to choose. They come with multi-element filters as well as single element cartridges. Pool builders are more likely to install a filter multi-element filter with four cartridges for the well-functioning of the pool filter. The cartridges of the cartridge filter trap the dirt and debris in the water. This too can vary according to the size of the swimming pool. They usually come with plastic or PVC wrapped and pleated from spun polyester. The clean water gets collected at the centre of the cartridge filter while the dirt and the debris gets collected outside.
It is better to clean a cartridge filter at least two or three times every three years. The cleaning can last around one hour where you can take the cartridges out if you want. Cartridge filters will last for around eight years if you use them in the best way and replacement is not difficult at all. Once it is replaced, it would work as a brand new filter. There won’t be any trouble as from the sand filter or the DE filter.
Which one is the best?
Well, now you know all the three filters and the significant differences among all the three. Every filter has its advantages and disadvantages, so it is up to you to choose. Consider the type of your swimming pool. How often you are going to use and consult the ideas of the pool builders and come to a conclusion. Hope you enjoy your swimming pool with choosing the best pool filter
