… OR A £95 ONE THAT CLEANS ITSELF?

LARQ £95 livelarq.co.uk

Billed as the world’s first self-cleaning water bottle and waterpurification system. It uses UV-C LED lights in the lid to kill bugs – including bacteria and viruses – living in your water and bottle.

Joseph Joseph click lid £13 connox.co.uk

One for the digital-phobes. Simply twist the lid on every refill of the 600ml bottle and a white dot appears. The more dots you accumulate – the lid can show four – the more water you’ve drunk.

Bellabeat Spring £79.99 johnlewis.com

Shake this bottle for an immediate reading of how much water remains in the flask, and therefore how much you’ve drunk. Sensors in the sleeve beam this information back to a paired smartphone app which turns your hydration data into easy-to-read graphs.

Thermos smart lid £36.80 thermos.com/ smartlid

This device features sensors in the lid and tube that detect the volume and temperature of the water. Users can hook up the bottle to other tracking devices for a personalised drinking plan.

Ulla smart hydration tracker £21 amazon.co.uk

Turn any bottle ‘smart’ with this attachable strap and sensor that flashes if it detects fewer than two sips every hour. Works with any shape, size or material and can be strapped to a drinking glass.

Equa £68.40 myequa.com

This sleek option issues reminders – the bottom of the bottle glows three times when its algorithm decides it is time for you to drink. The stainless-steel material keeps water cold for 24 hours and hot for 12 hours.
