does the CB249A-HCQ-DP 9KG need a filter or is it included

The CB249A-HCQ-DP 9KG unit does not come with a built-in water filter. It is recommended to use a separate water filtration system to ensure the quality of the water used, especially if you are using it in conjunction with equipment like ice makers or other water-consuming appliances. For optimal performance, you might consider adding a dedicated water filter system to your setup. For example, you could utilize the Bromic WF Water Filter System, which includes all necessary components for installation and effectively reduces chlorine, dirt, and rust. Alternatively, the Blue Seal FILTERMAX systems, such as the EF30 (20 Litres) or EF40 (40 Litres), might also be great options. They are designed for excellent water filtration and offer features like easy cleaning and a reusable filter bag. If you're looking for advice on which system to incorporate, feel free to ask, and I can assist further!
