JH Cockerell only recommends DIN-19643 standard filters

Effective filtration is the critical element for pool water treatment and can only be achieved with commercial filters, designed and manufactured to a recognised standard.
JH Cockerell only recommends filters designed to the DIN-19643 standard, in order to achieve healthy pool water with a probability bordering on certainty. No other filters can provide the same level of protection to keep swimmers safe and healthy.
According to State Health Department Guidelines: “Effective filtration is essential pre-treatment to effective disinfection.”
