Pool filtration types : Pros and cons of each system

Maintaining clean and healthy pool water is essential for fully enjoying this relaxation and leisure space. Filtration plays a crucial role in this process by removing impurities, algae, and microorganisms present in the water.

However, there are different types of pool filtration systems, each with its own advantages and disadvantages. Choosing the system that best suits your needs depends on several factors, such as pool size and type, budget, and personal preferences.

In this article, we will explore the three main types of pool filtration: 

1. Sand Filtration
2. Cartridge Filtration
3. Diatomaceous Earth Filtration 

1. Sand Filtration 

Sand filtration is the most common and economical system for pools. It uses a filter filled with crushed sand to capture impurities in the water.

Advantages: 

• Affordable purchase and maintenance cost
• Robust and durable system 
• Good filtration capacity for impurities
• Easy to use and maintain 

Disadvantages: 

• Less fine filtration compared to other systems 
• Higher water consumption during filter washing 
• Filter bulkiness 

2. Cartridge Filtration 

Cartridge filtration uses filter cartridges made of fabric or paper pleats to trap impurities.

Advantages: 

• Finer filtration than sand filtration, capturing smaller particles
• Generally smaller filter bulkiness
• Easier and less water-consuming filter washing 

Disadvantages: 

• Cost of filter cartridges
• Need for regular cartridge replacement 

3. Diatomaceous Earth Filtration 

Diatomaceous earth filtration uses diatoms, fossilized microscopic algae, to capture impurities in the water. This system offers the finest filtration of all pool filtration types.

Advantages: 

• Extremely fine filtration, capturing even the smallest particles
• Crystal clear water
• Silent operation 

Disadvantages: 

• Higher purchase and maintenance cost 
• Complexity of use and maintenance 
• Diatomaceous earth consumption requiring regular replenishment 

The choice of filtration type for your pool depends on your needs and budget. If you're looking for an economical and easy-to-use system, sand filtration is a good option. If you prioritize finer filtration and crystal clear water, cartridge or diatomaceous earth filtration may be better suited.
