Where I go to uni, the water don't taste so great (at least not up to the Yorkshire Water standards that I've become accustomed to in my 22 years of life); with this first-world problem laying heavily on my mind, I endeavoured to buy a water filter.

I did the necessary research first to find a good product, but being someone fixated on the aesthetic qualities of technology, I found the Brita Elemeris filter to be one of the better-looking models; it has a very simple and modern design that I like. The device also comes with a meter that tells you when to replace the temp. filter, which is very helpful.

This was a good decision - my water is now much fresher and tastier as a result. Having it constantly refrigerated is the best way to keep it, though you will have to keep washing it to ensure it's clean. This isn't a problem as it's very simple to dismantle the product and you have the option to put it in the dishwasher, providing you're even lazier than I am.

The only really annoying thing is making space for it in your fridge - we share one fridge between six of us at Uni, so I don't always have room to store the filter. Make sure you do actually have the required space in the fridge beforehand. However, the size does mean that the jug stores a lot of water (3.5 litres; it is an 'XL' after all), which is an obvious bonus.
