Katadyn Vario Water Filter

Katadyn Vario Water FilterIt is a portable pump with a 0.5-liter flask and a charcoal filter. The system is like stationary home cleaners. You manually pump the water which, after passing through the filter, accumulates in the flask.

The difference from the similar analog of Lifestraw is a combination of ceramic, charcoal, and glass filters. Each of these filters performs its function and detains different kinds of particles, viruses, and bacteria.

This becomes crucial in places with a dry climate. There are no large ponds and the water is heavily contaminated. According to users, it cleans even the dirtiest water from the swamp.

The total capacity is 2000 liters. It will be enough for several expeditions to the unexplored wilderness areas.

The price of this model is rather high due to its cleaning speed and materials in the filter. But it is not overpriced, because it is a filter from the pioneer company in the market – Katadyngroup. Unlike LifeStraw, the brand Katadyn has no army roots. But is a pioneer in the production of portable water filters.

The most remarkable detail. Per-minute the device is able to purify up to 2 liters of water, which passes through 3 stages of treatment. This is a record for compact models.

Survivor Filter PRO

Survivor Filter PRO Are you going to furrow the dearest corners of Africa or India and want to forget about problems with clean water?

The best filter station in our top will cope with this task – it will clean even the dirtiest water. Considering the pleasant, it is the most profitable investment for such extreme journeys.

Filters are not afraid of dirt. You can say about this model with a unique three-stage water purification system. It is like the one used in stationary household filters.

It works in the following way: the first external pre-filter stops the largest particles, preventing them from reaching the next stages. By doing so, it ensures the durability of the structure and serves as a natural load.

Thus, it allows you to immerse the tube deep in water. The second stage allows the liquid to pass through the classic carbon filter. In the third stage, water passes through a special “eternal” membrane filter.

It sifts out the remaining particles. Even if their size is 0.01 micron, which is one of the best on the market. In total, we get the ideal system for cleaning any, even the most neglected source with whole bacterial civilizations.

The throughput capacity is 200 ml per minute. Don’t forget that the filter isn’t foldable and certainly not a pocket filter.

Thus, you will have to provide a separate place in your camping backpack for it. Unlike the same LifeStraw, this model may seem too oversized. But the advantages are obvious: more than one filter from the top has not achieved a better result.

LifeStraw Personal Water Filter for Hiking

LifeStraw Personal Water Filter for HikingThis is one of the most popular models of filters among similar ones. Where did you get such popularity from? The first thing that attracts you is its compact size and ergonomic design.

The filter is in the form of a small tube. The device works on the principle of a cocktail straw with a built-in cleaning system, turning any muddy pond into a life-giving source. You can use it only as a personal tourist filter.

The purification process looks like this: you collect water from a natural source into a flask or any other container.

Then put the Personal Water Filter into it and slowly pull the liquid to be cleaned through the tube. This is quite simple.

It protects the device from all kinds of bacteria from LifeStraw. So with it, you can forget about E. coli and other unpleasant microorganisms waiting for you in hot and humid climates. But it will not clean the water from chemicals, salts, viruses, heavy metals and will not cut the unpleasant taste either.

Extreme enthusiasts have even treated sewage in one of the metropolises with the help of a device. So this gadget will surely cope with rainwater or spring water. It grabs the filter’s purification capacity for 1000 liters.

The best model in the category is also due to its simple design. It cleans the filter elementary at any time, unlike some other models. They are not at all disassembled.

FAQ for portable water filters buyers:

What will a 1-micron water filter remove?

A 1-micron filter will remove particles which you can’t see with the naked eye but is far less likely to reduce lead and heavy metals, or parasitic cysts giardia cryptosporidium. In fact, there are even smaller filters available for those.

Do any water filters remove viruses?

Generally speaking, a water filter is designed to remove waterborne protozoa and bacteria, but not viruses. A water purifier is designed to remove protozoa, bacteria, and viruses, offering a higher level of defense.

Can you drink any water with LifeStraw?

With the LifeStraw, you can drink directly from a water source (such as a stream, mud puddle, or lake), but keep in mind the ground might be soggy. Although the LifeStraw has been tested up to 422 gallons (1600 liters), you’re supposed to stop using it after 1000 liters.

Which Sawyer vs LifeStraw is better?

Whereas LifeStraw’s technology has been rated to 0.2-micron pore size, the Sawyer Mini rates at 0.1. Though both products meet EPA drinking water standards, the Sawyer Mini is the slightly superior water filtration technology. LifeStraw filters out “99.9999%” of bacteria and “99.9%” of protozoa.

Can you filter seawater into drinking water?

Desalination is the process of purifying saline water into potable freshwater. Basically–turning ocean water into drinkable fresh water. Reverse osmosis and distillation are the most common ways to desalinate water. Reverse osmosis water treatment pushes water through small filters leaving the salt behind.
