Let’s review two different types of filters so you can determine which one is right for your pool and your family. 

DE Pool Filter

What is a DE pool filter?

A DE filter, which stands for diatomaceous earth filter, utilizes a unique material known as diatomaceous earth to effectively clean and filter the water in your swimming pool. Diatomaceous earth is composed of the fossilized remains of tiny aquatic organisms called diatoms.

DE Pool Filtration

According to information provided by Pool Center, this type of filter can capture very small particles, with sizes as minuscule as three microns. This impressive capability is largely due to the fine texture of the diatomaceous earth powder that is used in the filtration process. So,  

  • The structure of DE pool filters consists of tiny hollow shells. 
  • These shells help trap dirt and debris. 
  • They ensure the pool water stays clear and clean for swimmers. 
 

When the powder is added directly to your pool skimmer, it reaches the grid, a nylon fabric. The DE then covers the grid, and it only allows water to get through, trapping the dirt on one side. When the filter cannot be cleaned anymore, which should be about a year, you may notice a slower flow rate. At this point, the system is backwashed, and you add more DE powder to the skimmer. 

Diatomaceous earth filters give the cleanest water out of the other filter options, according to Pool Supply World. 

Although maintaining a cleaner and more pristine swimming pool may indeed require a higher initial investment, it is worth noting that diatomaceous earth (DE) powder itself is quite reasonably priced when you compare it to the costs associated with other types of pool chemicals that are commonly used. 

This makes DE powder an appealing option for pool owners looking to enhance their pool’s cleanliness without breaking the bank. 

Cartridge Pool Filter

Cartridge filter uses

Cartridge filters are popular for spas and above ground pools. These filters trap particles down to five microns in size. 

Cartridge filters are made of a fine screen made from polyester material. 

  • The screen captures dirt and impurities from the water. 
  • These filters are typically housed in a small tank for effective operation.

As time passes, the filters will get dirty. This will cause more pressure in the tank. This high-pressure signal means it’s time for maintenance. Generally, this cleaning process should be performed approximately every six months. Fortunately, the cleaning procedure is quite straightforward.  

To clean the cartridges, you simply need to use a hose to rinse off the accumulated dirt and debris. This method is different from some filtration systems because it does not need any backwashing. This makes maintaining cartridge filters easy and without hassle. 

How long should a cartridge pool filter last?

These filters have a large amount of surface area and therefore work best at slow flow rates. This makes cartridge filters more energy efficient than other filtration methods, and they use less water. The downside is that these filters need to be replaced every three to five years. The good news is that your local Phoenix or Texas pool service can easily do this for you. 

What pool filter is best?

When you are trying to decide which pool filter will be the most effective for your pool, it is important to consider the various kinds of debris that tend to accumulate in your pool.  

For example, if you notice that your pool frequently accumulates tiny particles that can be difficult to see, then you might want to consider using a diatomaceous earth (DE) filter. This type of filter is specifically engineered to focus on and eliminate smaller contaminants that other types of filters may struggle to capture effectively.  

The unique structure of diatomaceous earth traps these minute particles, keeping your pool water clear and clear.  

On the other hand, if your pool tends to collect larger debris items, such as leaves, twigs, and other similar objects, then opting for a cartridge filter would be a more suitable choice.  

A cartridge filter is designed with the capability to handle and efficiently filter out these larger pieces, ensuring that your pool remains free of bulky debris that could affect the overall cleanliness and enjoyment of the water.  

By selecting the right type of filter based on the specific debris you encounter, you can maintain a more inviting and pleasant swimming environment. So, knowing what kind of debris is in your pool can help you choose the best filter for your needs. 

Frequently Asked Questions (FAQ’s)

1. Benefits of using diatomaceous earth in pools

Diatomaceous earth is natural and is composed of tiny aquatic organisms. The combination of fossilized remains from these organisms is what makes it so specific.  

Utilizing fine particulates trapped space down to 3 microns that keep bad pool purity, diatomaceous earth, DE filters indeed have this powder made specifically for trapping exhaustively small debris. 

2. Which Is More Effective: a DE Filter or a Cartridge Filter?

Both are effective; however, regarding cleanup, a DE filter would be superior because it can catch ultra-fine particles. So, it’s the cleanest water you can get. Cartridge filters are not as fine (down to 5 microns) but are much easier to maintain and more efficient with energy. 

3. How can a DE filter be cleaned?

Standard filters are cleaned by back flushing and recharged with DE powder once a year, or even when it is observed that the water flow has decreased significantly. Also, a general inspection is recommended for it to be at its optimal performance level. Need help? We’re here for all your pool maintenance and service needs.

4. How do you clean a cartridge pool filter?

A cartridge filter should be cleaned every six months. It should be removed from the unit and rinsed with a garden hose to remove muck and debris. 

5. Is DE powder expensive compared to other pool chemicals?

Not at all. DE powder is relatively affordable, especially when compared to the ongoing costs of other pool chemicals. This makes it a cost-effective option for those seeking premium water clarity.
