How to Buy the Best Pool Filters
Here, we will share some of the essential tips that will help you in buying the best pool filter.
1. Size and Volume
If you want a pool filter to work effectively then determining the size of the pool is crucial. A pool filter should be used at least twice in 24-hours to eliminate all the impurities of the water.
In case of commercial pools, the same has to be done at least 4 times in a day. You can only calculate the pool turnover rate when you know exact size and volume of the pool.
This information will help in selecting right model that will work effortlessly for a specific pool type.
Here are some steps that you can follow to find the befitting product.
- Step 1: In order to calculate total volume of the pool, there formulas are different as per the pool shape. Square or rectangular pool formula: length x width x depth. Circular pool formula: radius x 3.14 (pi) x depth.
- Step 2: If you have to calculate the capacity in gallons then you can do it multiplying 7.48 with the total pool volume.
- Step 3: Flow rate of water can be calculated by the formula: Pool Capacity/turnover rate. The TR refers to the total time needed to circulate body of water equals to the pool capacity.
It is essential to pick a filter whose flow rate is synonymous with the flow rate of the pool.
2. Type of Pool Filters
There are three prime types of pool filters that are popular among buyers. Let’s take a comprehensive look:
DE Filter: Well, if you have high budget and want to buy the best pool filter system then Diatomaceous Earth (D.E.) filter should be your choice.
This will not allow even the slightest particle of 5-micron to pass through and is the most performance-savvy filter among all others.
The tank is equipped with grids or fingers coated with crumbly white powder. This powder is derived from the remains of aquatic organisms known as diatoms.
Plus, the powder used here is heat treated for the filtration process. The pressure gauge tells when the backwashing is required.
It is important to add more DE powder after each cleaning. You are recommended to clean the filter with hand, at least once in a year.
The benefit of this filter is that it is extremely efficient. The powder can easily be added through pool skimmer.
As far as the drawbacks are concerned, this one will cost extremely high and demand a lot of cleaning. Plus, the DE powder is toxic and should not be inhaled.
Sand Filter: These are most budget-friendly filters among all others. Also, this does not demand a lot of maintenance. This is a considerable choice for large pools because it does not clog as much as its counterparts.
As far as the working mechanism is concerned, the pool pump sucks the water in from the skimmers and then transfer it to the large filtration tank where there is sand. This helps in grabbing the particles that are 20-microns or higher in size.
The sand used in the tank is of high-quality and has rough edges that holds the contaminants passing through the filter.
After continual usage, the performance of the filter is hampered because the edges get softer and eventually become incapable of holding impurities.
The benefits are that the filter is economically priced and does not demand any maintenance for many years. However, the drawbacks are that the building pressure will affect the efficiency of the filter.
Cartridge Filter: These filters are relatively expensive than the sand filters. But, these are quite easy to maintain. They are more suitable for smaller pools.
The tank is comprised of plastic cylinder with pleated polyester filter media and is capped on all the sides. Water comes inside the tank through these pleats which is capable of grabbing debris as small as 10 microns.
These are not as expensive and completely energy efficient. After grabbing all the contaminants, you will then have to clean the cartridge. Well, that’s pretty easy as you can simply remove the cartridge from the filter and clean it with water.
You can sometimes use filter cleaner or soak it in diluted muriatic acid and thoroughly clean the cartridge.
The benefit is that these can capture up to 10 microns of debris and are more efficient. Also, backwashing requires less water wastage. But, the life is smaller than the sand filters plus, it may ask for deep cleaning once or twice in a year.
Our recommendation of the best cartridge pool filter is the Intex 28633EG pool filter as it has high-brand value, great performance and is available on the most-affordable price.
Well, its evident from the description above, the sand filters are for budget buyers. Cartridge filters are for the people with smaller pools. And people who don’t mind spending hefty amount of money but want the most efficient filters should buy DE filters.
3. Top Mounted or Side Mounted Valve
Top mounted valve poses less installation charges on the users plus, these are easy to maintain while the side mounted will cost largely. The processing does not differ a lot in either cases so its up to you how you want to install the filtration system.
How to Clean the Pool Filter

For the other kind, there is a handle at the filter top which is knocked and DE is removed along with the debris. Turn the pump off and then follow the below steps:
- Use 5 seconds to open and shut the top air valve
- Now, restart and see of the PSI has gone down more than 2 PSI
- If such has happened, you can go to the next step or repeat 1 until its done
