A water bottle that can filter 99.9999% of bacteria AND viruses.

Pure Clear says: 

The Pure Clear®-Active water bottle has been designed specifically for sport and outdoor activity. The water bottle is light weight yet solid and can be filled up from tap water sources such as at the gym or sports centre, toilet tap, home and even abroad. If your preference is more extreme like hiking, camping, survival and the outdoors, the patented technology within the filter gives you the ability to filter water from outdoor water sources.

The Pure Clear-Active bottle is BPA and BPS free. It is also completely free of estrogenic and androgenic activity and is recyclable, meaning it is the safest manufacturing plastic available to date. The Pure Clear-Active water bottle has a single press button to release the lid via a spring action (which is anti-rust - stainless steel) so it is simple to open should you have your hands full. Once open it showcases a silicone mouthpiece, which is soft and comfortable to drink from.

Inside the bottle itself is the filter cartridge housing and straw. The housing and straw simply twist away from the lid becoming two separate pieces. The body of the filter cartridge then twists again in the centre, which exposes the Active filter.

There is a band around the centre of the housing which has 1 - 12 marked on it to indicate the month of the year and when the filter was introduced. Simply twist the band with the corresponding number on, to point at the arrow marked on the body of the housing. You can now see when the filter was introduced and if it requires replacement.

"As the filter removes 99.9999% of all bacteria and removes 99.99% of waterborne viruses, you can take the Pure Clear-Active water bottle on holiday with you and use it down by the pool with a healthy scoop of ice inside it and stay rehydrated all day without the worry of any nasty surprises later in the day."

Wherever you are in the world, even at home it is essential to filter your water. According to an in-depth article written by the Guardian newspaper it is now common knowledge that the UK does not test our drinking water for a group of toxic manmade chemicals linked to a range of diseases including cancers.

Our Verdict

I admit I had to do a double-take when I got my hands on this water bottle; I had to ask my boss if I had this right, a bottle filter that can filter viruses? This product is potentially game-changing. It’s also incredibly reasonably priced, half that of most other brands.

Pure Clear suggests changing the filter every two months or 200L of water. Replacing the filter is incredibly easy, and each filter is reasonably priced. You do not back flush the filter! This may mean, on longer trips, you may have to carry an additional filter, which some people will be put off by.

You can use this filter anywhere and be confident you are getting safe drinking water, whether at home or abroad, in the gym or the mountains.
