What is the primary reason for using cartridge filters in swimming pools?

The use of cartridge filters in swimming pools is primarily favored for practical reasons related to their efficiency and maintenance. One key aspect of cartridge filters is their capacity to manage water quality effectively in various pool sizes, particularly for smaller pools, typically under 80,000 gallons. They have become a popular choice for these pools due to their ease of use and lower maintenance requirements compared to other filtration systems, like sand or DE filters.

Cartridge filters can effectively trap debris and contaminants in the pool water, which contributes to overall sanitation. Although they do not specifically target bacterial reduction or heavy metals, they play a vital role in maintaining clearer and cleaner water in conjunction with proper sanitization practices. Their design allows for easy cleaning and replacement without needing backwashing or extensive downtime, making them a user-friendly option for pool owners needing reliable water filtration.
