Types of Pool Filters

There are three different types of pool filters – sand filter, cartridge filter, and D.E. filter. Before you start shopping, you should learn about the pros and cons of each filter to determine which one is right for you. Below we have shared some information about the three different types of pool filters.

Sand Filter

Sand filter is the most common type of pool filter. It is the least effective filter available in the market. Sand filter can filter particles ranging from 20 to 40 microns. Sand is used by these filters for filtering dirt and other organisms from the pool water. Once the dirt or debris is at full, the pressure within the filter increases, indicating that the filter needs to be backwashed.

To backwash, you would just reverse the normal flow of water through the filter. To change from filter to backwash mode, a multiport valve is used. You need to use extreme caution in backwashing your pool due to the potential for causing damage.

There are a few things you need to think about before purchasing a sand filter. The first issue is that frequent backwashing can disrupt the water chemistry and level of a pool. The pool may need to be refilled and rebalanced after being backwashed. There would be a loss of capital due to the unnecessary use of chemicals and water. Moreover, you’ll need to determine where the water will be backwashed. A sand filter valve is also required for use. The filter may or may not include the valve.

Pros of Sand Filter

  • The most affordable and compact
  • Easy to clean
  • Minimal maintenance
  • Straightforward operation

Cons of Sand Filter

  • Lower filtration ability than D.E. and cartridge filters
  • Constant backwashing will throw off the water balance and level
  • More cost on water and chemicals

Cartridge Filter

Cartridge filter is another common pool filter that uses pleated cartridges to maximize the square foot area of the filter. The greater the surface area of the filter, the more dirt it will filter out. Cartridge filters are capable of capturing particles as tiny as 10 to 15 microns. When it comes to efficiency, cartridge filters are better than sand filters but not D.E. filters. However, maintaining them is very ease.

When the cartridges get too dirty, the pressure in the filter will rise, which indicates that it is time to clean the filter. Depending on the pool water chemistry, cartridges generally need to be cleaned after every six months. Cartridges may be cleaned or replaced, and there isn’t any need to backwash this type of filter.

Cartridge filters work well at slow flow rates. A very large pool pump can push the water through the cartridge filter, bypassing the filtering stage, which makes the filter useless. It is essential to use a moderate-sized pool when using a cartridge filter. Cartridge filters generally utilize less water and unlike sand filters, they would save you money on water and chemicals.

Pros of Cartridge Filter

  • Easy to clean and replace the cartridges
  • Low maintenance
  • Easy to install

Cons of Cartridge Filter

  • Heavy debris buildup can clog the cartridges. You might have to rinse the filter more frequently
  • The price of these filters is generally high
  • Doesn’t work well with fast flow rates

Diatomaceous Earth Filter

If you want the best filter for your pool, then go with D.E. filters. They are similar to sand filters but use a different approach to filtering. In D.E. filters, fossilized remains of diatoms are used for filtering the pool. They are capable of collecting debris and microorganisms as small as 2 microns. A D.E. filter provides more thorough cleaning than both a cartridge and a sand filter.

D.E. powder coats the grids of the filter and allows water to get through them, trapping the dirt on one side. However, D.E. filters need to be cleaned through backwashing. Like other filters, you will have to monitor the pressure gauge of D.E. filters to determine when they need backwashing. These filters also require pool owners to routinely clean the elements of the filter. Soaking the grids removes all the dirt, oil, stains, and minerals from the fabric of the filter. This is the reason why D.E. filters need the most maintenance.

Pros of Diatomaceous Earth Filter

  • Exceptional filtration ability
  • If you properly care for grids, they would last for several years

Cons of Diatomaceous Earth Filter

  • D.E. media must be added to the grids after every backwash
  • Higher maintenance costs
  • It takes time to disassemble the filter grids
  • A backwash valve is required to operate this filter

Buying Guide for Pool Filter in 2023

When you are choosing a pool filter, there are some important things to consider. These include:

Consider the Size

Make sure to choose the filter that is of the right size for your pool. A filter that is too big would work fine but you will end up wasting tons of money. On the other hand, if the filter is too small, it won’t be able to meet your pool’s cleaning needs. Before you make the purchase, size the pump and the filter.

How to Size the Pump

Your first step should be to calculate the ideal pump size. The volume of your pool in gallons will be required for this. You might think of the 18,000 gallons of water that are contained in your pool. Next, you’ll need to choose a filtering rate that will allow you to get the water back to your desired temperature and pressure level as rapidly as possible.

Suppose you have set a 6-hour deadline for the filtration process to end. Divide the total volume of water in gallons by the total time needed to filter the water to determine the size of the pump. The result is then divided by 60 to get the number of minutes in an hour. The result is a rate in gallons per minute.

18,000/6= 3,000 gallons per hour

3,000/60= 50 gallons per minute (GPM)

50 GPM is the flow rate. With this number, you can start finding the right sized pump for your pool.

How to Size the Filter

Once you have calculated the size of the pump, you can start making an estimation for the filter. For sand, the estimation is easy – 1 sq. ft of filter for every 10,000 gallons of water in your pool. In the example given above, you have 18,000 gallons of water. If you are going for a sand filter, this means you should be at 1.4 sq. ft. of filter area.

However, while you should not buy a filter that is too large, you can go touch large on the filter surface area as it would put less strain on the filtration system. You could get a 2 sq. ft., and it would work well for your pool.

Consider the Cost

Pay attention to the price tag of the filter. There are some very expensive filters available in the market. They are a great option if you need something durable and reliable. However, this doesn’t mean that you have to spend a lot of money to get your hands on a good-quality filter. There are several budget-friendly models that would do a good job of cleaning your pool.

Final Thoughts

We have discussed some of the finest pool filters currently available in the market. Now, it should be easier for you to select a filter for your pool. When making a purchase, pay attention to the size of the filter and the pump to ensure that you get the right model. If you have any questions, feel free to reach out to us.
