Purisoo: Portable water filter can help you drink clean water anywhere

Even if you're in a polluted water source, just with Purisoo, an innovative portable water filter will help you get a glass of clean water right away to quench your thirst.

One of the top problems that people face today is clean water security. In the context that natural freshwater resources are gradually scarce, there are still many places on Earth, water is so seriously polluted that it can be drunk and living.

To temporarily resolve the polluted water situation in the short term, people invented water filters of all sizes, maybe even as small as a portable drinking water bottle.

There are currently two popular ways to filter water: use a portable pump filter or bottles with a built-in filter. However, both of these devices have limited points and it is difficult to meet the demand for drinking water for each individual for a long time.

Originating from this concern, Korean start-up named Purisoo has created a portable water filter capable of absorbing water inside, purifying and creating pure drinking water for users.

The design of Purisoo bottle is quite compact with the size of 7.62 x 27.94cm, weighs 567 grams and is suitable to carry anywhere and anytime. Bottles using filters from well-known brands such as LifeStraw, Katadyn and Sawyer should ensure maximum quality.

The filter integrated bottle is gradually gaining popularity, but the disadvantage of this bottle is the need to pour untreated water through a filter funnel. This can cause dirty water and bacteria to settle at the top of the bottle, making it dangerous to drink.

However, Purisoo solved this problem by separating filters and water storage. Understandably, the water will be pumped into the three-layer filtration system before flowing into the clean water range for drinking. The final drink will be taken at the end of the bottle.

Just turning the bottle over was able to drink clean water.

One advantage of this device is that there is an extra 1 meter extension tube that draws water from hard-to-reach sources.

Purisoo has the same working principle as a pump without having to carry an internal pump. Even so, Purisoo still has drawbacks when the water capacity is not large, only about 0.4 liters instead of over half a liter like many current bottles.

Purisoo's internal filter has a long life span, about 1000 liters of water for each use before replacement.

Currently Purisoo is just Kickstarter project and has a starting price of about 69 USD (about 1.5 million VND) including bottle + filter + extension tube.
