Which factor can affect the efficiency of pool filtration?

The efficiency of pool filtration is significantly impacted by the type of filter media used. Different filter media, such as sand, diatomaceous earth, or cartridge filters, have unique characteristics that influence their ability to trap particles and contaminants from the water. For instance, diatomaceous earth offers superior filtration due to its fine structure, capturing smaller particles that other methods might miss. In contrast, sand filters may be more effective for larger debris but may allow some smaller particles to pass through.

Additionally, the filter media's surface area and the flow rate can also play a role in overall filtration efficiency. A higher surface area allows for more contaminants to be collected, leading to cleaner water. Therefore, when selecting a filtration system, the type of filter media is crucial for ensuring optimal water clarity and hygiene in a swimming pool environment.
