The Ultimate Guide to Pool Filtration Systems: Choosing the Best for Your Arizona Pool

When it comes to keeping your pool water crystal clear, choosing the right filtration system is crucial. In Arizona, where dust and heat are constant companions, the need for an efficient and reliable pool filter is even more critical. At AZ Valley Pools, we recommend Hayward brand equipment for its superior quality and performance. In this guide, we will delve into the three main types of pool filtration systems: Diatomaceous Earth (DE) filters, Cartridge filters, and Sand filters, highlighting their pros and cons to help you make an informed decision.


Diatomaceous Earth (DE) Filters

Overview: DE filters use a fine powder made from fossilized diatoms to capture even the smallest particles. These filters are known for their exceptional filtration capability, providing the clearest water of all filter types.


  • Superior Filtration: DE filters can trap particles as small as 2-5 microns, ensuring your pool water is exceptionally clear.
  • Efficiency: They require less backwashing compared to sand filters, which conserves water.
  • Chemical Usage: With DE filters, you generally need fewer chemicals to maintain water clarity.


  • Maintenance: DE filters require more frequent maintenance, including regular backwashing and the addition of DE powder.
  • Cost: They are generally more expensive to purchase and maintain than other types of filters.
  • Complexity: The process of adding DE powder can be more complex and time-consuming.

Cartridge Filters

Overview: Cartridge filters use replaceable cartridges to filter out debris. They are known for their ease of maintenance and high filtration efficiency, making them a popular choice for many pool owners.


  • Ease of Use: Cartridge filters are simple to maintain, requiring only periodic cleaning and occasional cartridge replacement.
  • Water Conservation: They do not require backwashing, saving significant amounts of water.
  • Efficiency: Hayward SwimClear 4030 Cartridge Filter, is our preferred model, excels in capturing fine particles and handling heavy debris loads, which is essential in dusty Arizona environments.
  • Energy Savings: Cartridge filters operate at lower pressure, which can save on energy costs.


  • Replacement Costs: The cartridges need to be replaced periodically, which can add to the overall maintenance costs.
  • Cleaning Frequency: In areas with heavy debris, such as Arizona, you might need to clean the cartridges more frequently.

Sand Filters

Overview: Sand filters use a bed of sand to filter out impurities from the pool water. They are the most common type of pool filter due to their simplicity and low maintenance requirements.


  • Simplicity: Sand filters are straightforward to use and require minimal maintenance.
  • Durability: They are durable and can last for many years with proper care.
  • Cost: Sand filters are generally more affordable both upfront and in terms of maintenance.


  • Filtration Quality: Sand filters are less effective at capturing fine particles compared to DE and cartridge filters, typically trapping particles down to 20-40 microns.
  • Backwashing: Regular backwashing is necessary, which can lead to significant water usage.
  • Efficiency: They are not as efficient as cartridge filters, which can lead to higher operational costs over time.
