We all know the importance of water for people's survival: you can survive for 3 weeks without food, but you can only survive for 3 days without water. Therefore, for the travellers, outdoor water holding appliances and water purification equipment are also very important. Today, let's talk about this topic.
Plastic sports water bottles, thermos cups, water bottles for running pockets and even bottled water bought in supermarkets are all commonly used water containers for outdoor sports or short-distance outdoor activities. They are very common and easy to buy.
Outdoor kettles, military kettles, and even multifunctional kettles with integrated stoves and lunch boxes are also very good. They can be put together to save space.
This kind of water bottle is usually not common in the market, but some special outdoor products franchise stores or a universal treasure are also available.

Nowadays, there are many soft kettles made of silicone and other materials on the market. The biggest advantage of this type of kettle is that the volume decreases with the consumption of water. After all the water is consumed, the volume is usually very small. Portable. When you actually use it outside, you can choose to use the water first to minimize the load.
Like the soft kettle, it has an advantage in volume, and the volume can be reduced as the water in it is consumed. When you are outdoors, you can put it in the hydration bag of your backpack to cool your back when it is hot. Usually this kind of water bag comes with (or can be matched with) a suction nozzle, which is also very convenient to drink.

Of course, the filter water bottle can also be used to hold water, but its more valuable function is that it can also filter at the same time, which we will talk about below.
Because the 3L clean water we prepared can’t actually last long, the outdoor water purifier can solve the problem that we cannot replenish water in time when we travel long distances, especially when taking some remote routes. Since water is a key element for survival, it is recommended to have conditions, or to prepare 1-2 sets of water purification equipment in your backpack.
At present, outdoor water purifiers on the market can be divided into the following categories according to their functional principles: ceramic filter element filtration, fiber filter element water purification, ultraviolet lamp sterilization, iodine resin sterilization, activated carbon filter element water purification, etc. According to its power mode, it can be divided into: pump type (piston type, electric pump, hand pump), gravity leakage type, straw type, kettle type (squeeze type), etc.
Water bottle/bag type (squeeze type)
The appearance is like an ordinary kettle/bag. When using, put the water to be purified into the kettle (cup), and use the air pressure generated by the airbag/pot body to make the water in the kettle flow through the filter element with water purification function, and the bacteria in the water , Suspended pollutants and other harmful substances are removed, and the safe drinking water that can be consumed directly from the outlet of the water purifier.
Miniwell's L620 type, Pureeasy's sport, travel, and bottle in the katadynUltra-light series are kettle/bag outdoor water purifiers.
Pump type (piston type)
Immerse the water inlet of the piston-type (pump-type) outdoor water purifier into the water to be purified, and pump the rainwater, stream water and other natural water that needs to be purified into the water purifier through manual push or repeated movement of the electric piston. The water purification filter element removes harmful substances such as bacteria and suspended pollutants in the water, and safe drinking water that can be directly drunk flows out continuously from the water outlet. The domestic miniwell individual L610 and L800, the Swiss Katadyn Mini, hiker, pocket, etc. and the American MSR Miniworks and Hyperflow all belong to this type.
This type of outdoor water purifier is generally larger and heavier than other types, but after all, it is an outdoor water purifier, which is still very portable compared to a household water purifier.
Pump type water purifier
Both the SteriPEN series and MSR's ExpeditionMiox are pen-type water purifiers and generally require batteries.
Miniwell's L630G, MSR's Autoflow, Katadyn's DripGravidyn and Camp, etc. belong to the gravity leakage type, and gravity leakage outdoor water purifiers generally use ultrafiltration or ceramic filter elements as the main water purification technology. It is suitable for many people. The biggest advantage of this water purifier is that it saves the manpower for water purification. It can be filtered by using gravity when hung at a high place. Generally, the water output is not small.

The straw-type water purifier is also very portable. Usually it is smaller, lighter, and very portable. It is especially suitable for walking travellers, but this type of water purifier is not suitable for multiple people to share. Of course, some can be connected to a water bag or The purified water is squeezed from a plastic cup and shared with your peers, but the simplest and most direct way is to drink directly from the water source.
Miniwell's L600 and L630, Denmark's Lifestraw, are all straw-type water purifiers.
