ZeroWater 500ml Steel Bottle with UV-C Cap

£44.99

When you’re out and about this summer is so crucial to stay hydrated, and with ZeroWater’s steel bottle and UV cap, you can be sure that the water you are drinking is safe, germ-free, and always cold.

Looking first at the bottle, it’s a nice matte grey colour with a smooth-to-the-touch feel. ZeroWater’s branding on the side is stylish in complimentary white and blue lettering. It’s a sturdy bottle and is even dishwasher proof, unlike many brands of water bottles, making it easy and quick to wash up. The bottle has a double wall insulation design which keeps liquids cool for 24 hours, and hot for 12. The bottle is designed with a chic simplicity, is BPA free and even leak-proof – making it a great and stylish addition to any summer travel plans.  

I was particularly interested in the UV-C Cap design which boasts that it can keep your bottle clean and fresh by periodically blasting the bottle’s contents with ultraviolet rays. These rays sterilize the bottle through a 2.5-minute process from the bottle cap. Then once an hour the bottle is repeatedly sterilised for 20 seconds through the cap’s UV-C rays. The cap is said to remove all TDS (total dissolved solids) from your water which can include minerals, salts, metals, chemicals, fluorides, and runoff pollutants. It is meant to be particularly great at removing any excess TDS from your tap water. The filtration system, therefore, I supposed to leave you with germ-free water, for healthy hydration. One perk of this system is that it should also leave your bottle clean and without odour too!

When I tested out the bottle it worked great and kept my water cold while out and about for a long day in the sun. The UV cap did its thing all day, and while I didn’t notice any giant change to the water taste, and I do not own a chemistry set to test the water mineral level it seemed to do exactly what it said. It gives great peace of mind that while your water is in the bottle all day it is not developing any germs and will be there to provide you with clean and healthy hydration when you need it. If you are looking for a new water bottle and want one that you can ensure will keep your water germ free all day, this is a great choice to test out. However – I must note that is bottle does not filter water or remove chemicals, metals or plastic contaminants, so is only recommended for use with water sources which are already drinkable either from a water filtration system or from a household tap.

Pros:

- Keeps liquids cold for 24 hours and hot for 12

- UV Cap sterilized bottle contents hourly for peace of mind

- Removes all TDS through the filtration system

Cons:

- Cannot be sure if completely effective
