Filtration in water boilers - why it’s important

23 Dec 19

It’s not difficult to find out if you’re in a hard water area, you only have to look in the bottom of your kettle or at the white build-up around tap heads to notice the scourge that is limescale. This chalky deposit not only affects the day-to-day functioning of products but also causes hot drinks to look and taste off-putting.

What exactly is hard water?

Hard water is simply water that has a higher concentration of dissolved minerals such as calcium and magnesium. When the water evaporates it leaves behind deposits of calcium carbonate, which, if left untreated, is notoriously hard to remove.

Around 60 percent of the UK suffers from hard water, but even if you’re in a soft water area it’s still worth considering filtration to remove particulates to provide a purer-tasting cuppa. Many of us will be in the regular habit of manually descaling our kettle or adding a special scale-fighting cleaner to the washing machine, but for products such as water boilers, this is just not convenient or effective.

Not all filtration is equal

At Instanta, our commercial water boilers and chillers have a helpful warning system in-built to notify users of limescale build-up but we’d always recommend using the best filter possible as a preventative measure. We offer a range of filters to suit different levels of scale and volume of usage, between one and five microns. The smaller the micron rating, the better the filtration. To put it into perspective, the human eye can see dust and particles that are around 75 microns in size. 

Time for a filter change?

How often you change your filter depends on usage and water condition, but we’d recommend changing it at least every six months. This will keep your product running smoothly and make sure drinks are fresh-tasting. Many of our models will alert you as to when its filter needs changing, and on premium models, a filter monitor can be installed to allow you to see the duration of filtration you have remaining.

How you change your filter depends on the model you own. Certain models have integral filtration and have been designed with a very quick and easy mechanism to allow anyone to change it. However, most of our models have a quick-release cartridges that can be easily replaced, simply check your manual for more details on how to change your filter and which filter is most suitable.

Filtration is so much more than a ‘nice to have’ accessory, it’s a key part of product maintenance, not to mention the key to pure-tasting drinks. Please contact us on 01704 501114 if you have any filtration or maintenance queries.
