How to Choose a Cartridge Pool Filter

If you own a swimming pool, then you understand the importance of having a reliable pool filter system. The pool filter system is designed to remove dirt, debris, and algae from the water, ensuring that the water remains clean, clear, and safe for swimming. One of the most popular types of pool filters is the cartridge filter. In this article, we will tell you everything you need to know about how to choose a cartridge pool filter.

1. What is a Cartridge Pool Filter?

A cartridge pool filter is a type of pool filter that uses a replaceable cartridge to trap dirt, debris, and other impurities from the water. The cartridge is made from polyester or other synthetic materials, and it is designed to be washed and reused several times before it needs to be replaced.

2. Advantages of a Cartridge Pool Filter

One of the main advantages of a cartridge pool filter is that it is very easy to maintain. The cartridge can be removed and washed, and there is no need for backwashing, which can save a lot of water. Cartridge pool filters are also relatively inexpensive and are usually easy to install. They are also effective at removing small particles and debris from the water and help to keep the water clear and inviting.

3. Choosing the Right Size

When it comes to choosing a cartridge pool filter, you need to make sure that you get the right size. A filter that is too small will not be able to keep up with the demands of your pool, and a filter that is too large will be a waste of money. The size of the filter you need depends on the size of your pool. You can determine the size of your pool by measuring the length, width, and depth of the pool.

4. Choosing the Right Type

Another important factor to consider when choosing a cartridge pool filter is the type. There are two main types of cartridge pool filters: single-element and multi-element. Single-element filters are the most common and come in a variety of sizes. Multi-element filters are designed for larger pools and are made of several elements that can be stacked together.

5. The Cost of a Cartridge Pool Filter

When it comes to the cost of a cartridge pool filter, there are many factors to consider. The cost of the cartridge itself can vary depending on the size and type of filter you choose. You also need to factor in the cost of installation, which can vary depending on the complexity of the job. Finally, you need to consider the ongoing maintenance cost, which includes the cost of new cartridges and any other replacement parts that may be needed.

In conclusion, choosing the right cartridge pool filter is essential to keep your pool clean and clear. When shopping for a cartridge pool filter, consider the size and type of your pool, the cost of the filter and its installation, and the ongoing maintenance cost. With the right cartridge pool filter, you can enjoy a crystal-clear pool all summer long.

Bigger is not always better when it comes to pool pumps. A pool pump that is too large can hinder filtration and can even damage a pool’s filter and/or heater. It is therefore very important to know the size of a pool before purchasing a pool pump. If there is additional equipment (such as water features) installed into the pool, it will have to be taken it into account when deciding what size pump is going to be purchased. The more equipment is installed into a pool, the more powerful the pump needs to be.
It is important to consult with a pool equipment expert, such as Poolking's Pumps, before buying a pool pump. The team at Poolking will be able to give our customers professional advice regarding the size of the pump they will need to purchase.
