By Admin on Fri 26 May 2017 in Water Filtration FAQ's

Water filters for domestic use typically fall into 2 distinct categories

Point of entry units (POE) - This type of unit treats the incoming water supply before distribution throughout the household.

Point of Use (POU) - These units typically range from under the sink type filters, tap filters etc. filter pitchers), faucet filters, and under-the-sink units. Some filters use more than one kind of filtration technology. Whenever trying to choose the right filter for use within your household always opt for a certified product.

For the majority of UK residents a standard activated carbon water filter should be more than sufficient for most filtration jobs, however certain pollutants such as perchlorate if found to be present within the water supply then a standard carbon filter wont do.
