The Replacement filters maintain the high levels of filtration that The Healthy House™ Whole House water filters offer, maintaining healthier drinking, cooking and bathing water. The number required in each separate unit are as follows:
1 x pre-filter in the WW4 and WW5
The Pre-filter removes excessive impurities before the main filter and hence prolongs the life of that filter and ultimately saving you money.
The pleated pre filter for your whole house unit has been designed to be more efficient at reducing dirt, sand, sediment, silt, rust, scale and other particles from incoming water supplies. The large surface area is able to deliver high flow rates, maintain excellent dirt-holding levels and deliver extremely low pressure drops.
