Do you own a swimming pool? If yes, I bet you have ever asked yourself about the best pool filter, which is undeniably one of the most essential parts of pool maintenance. This article has all the information you need to know about it.
The principal purpose of a filter is to collect contaminants that get into the pool such as dust, algae, leaves, and bacteria. A filter plays a significant role in keeping your swimming pool clean and ensures that your equipment is functioning properly.
The effectiveness of a filter is determined by the size of particles it can collect. The particles are referred to as microns. If you are a new pool owner or you have an old pool filter, it’s time to buy a new one.

Types of Pool Filters
This is a circular filter which has a pleated filter material. This type of filter can capture debris as small as 10-15 microns. These types of filters are very easy to maintain, and they normally do a good job of keeping the water clean. They should be replaced at least once per year. The cost of replacing the cartridge depends on the size or square footage of the cartridge.
Sand filters remove impurities from water by use of sand to collect debris. Once the debris accumulates, the filter will require a backwash. You can do this by running the water in the opposite direction through the filter. They can filter debris between 20-40 microns and are not as good as cartridge filters. Sand filters are easy to maintain as they only need to be backwashed once after several weeks. The sand can be changed once after 3 or 4 years. These types of filter are bulky and hefty.
The DE Filter ( Diatomaceous Earth)
It contains grids inside which are coated with DE powder. They also have a filter media where mined and fossilized exoskeletons of tiny diatoms are used in powder to cover the grids. This filter can trap debris as small as 2-5 microns.
What Do You Have To Consider When Selecting The Best Pool Filter For Your Pool?
1. Calculate the volume – When choosing a filter for your pool, the first thing you should consider is the amount of water to be filtered. You can follow the following formulas when calculating the volume of your pool.
- For a rectangular pool – Multiply the width by the length and by the average depth.
- For a circular pool- Multiply the radius by 3.14 by the average depth.
2. Calculate the capacity –calculate the number of gallons of water that the pool can hold. To do this, multiply the pool volume by 7.48 ( which is the number of gallons of water in a cubic foot of volume)
3. Calculate the flow rate – This is the amount of water flowing past a given point at a specific time. It is usually measured in gallons per minute(GPM) or gallons per hour(GPH.)
To determine the flow rate, divide the capacity of the pool by the turnover rate which is the time needed to circulate a body of water equal to the size of the pool.
4. Decide the type of filter you prefer – Which is your favorite filter: sand, cartridge or diatomaceous earth filter? You should be able to determine this from your poolside experience.
5. Make sure you oversize the filter –When selecting a pool filter, it is important to understand that as the debris are removed from the water, the filter medium usually becomes clogged, and the filter will need a greater flow to clean an equal amount of water. Therefore, it is necessary to go for a larger filter than indicated by our calculations of flow requirements.
