FAQs on Replacing Your Water Filter

Why do I need to change my water filter?

Like any type of filter (car, air, oil etc), they eventually clog and stop working – they need to be replaced to maintain optimal performance.

The GWFL water filter is installed to remove chemicals and impurities. Those chemicals and impurities are absorbed into the carbon in the water filter. After approximately 2 years, the water filter will be saturated with those contaminants. Although water will still come through your tap, there is a substantial risk of leaking chemicals and bacteria back into your drinking water.

My water is ‘clean’, why do I need to change my water filter?

The question is less to do with the quality of the water or how “clean” it is – your water filter also filters out dirt, sand, sediment which will eventually clog your water filter.

I can’t taste the chemicals coming through my water filter, does it still need changed after 2 years?

Just because you can’t taste the likes of chlorine and heavy metals in your water doesn’t mean it is ok to drink. We also recommend the GWFL under sink water filter is replaced after 2 years because bacteria will have started to grow and it will be leaking into your water.

Is this just a money making thing?

The amount of filtration that your water filter can do is based on volume of water, science and number of people in a household, not £s. The GWFL water filter has the capacity to filter approximately 12,000 litres of mains water, which an average household will use generally within 3 years. 

Changing your inline Glacier GWFL water filter is much more cost effective than spending money on cartridges that need changed every month or every 6 months.
