The function of all water filters is the same in its ways.

Let’s check out some significant types of portable water filters with their pros and cons.

1. Straw Portable Water Filters

If you are looking for the lightest portable water filter, there is nothing best as Straw water filters available now.

Just like the name, the screens usually look like large straws, and they work as the straws as well.

If you want to use filters, you just have to get close to the water source and draw in water with the help of the straw.

It is fascinating to know that you can bring water from any source like lake, pond, river, or puddle.

However, it is essential to know that the filter requires a more powerful draw to work, but the process of filtration is very easy and straightforward.

People will glad to know that Straw filters use cartridges that are made out of the hollow fibre membrane.

Moreover, these fibres are tightly woven together. Water can easily pass through a lot of fibre layers before reaching the actual straw you are drawing on.

Furthermore, fibres of the filtration unit are also very porous, but the holes in the tissues are tiny.

Any of the membranes of this unit use holes that are 0.2 microns wide. In this way, one hundred thousand smaller, a 2 cm hole allows the water to pass.

The water passes through these holes to the straw. All the bacteria, viruses, and parasites in the water are more significant than the mess.

That’s why they will be trapped and won’t be able to pass.

In short, all the elements that float in the water are too large to pass. In this way, you can get rid of all types of contaminants present in water.

Pros of Straw Portable Water Filter

  • These filters efficiently remove all sediment and debris present in water
  • The screen can remove all the particles that cause the water to taste and smell bad
  • It can easily remove bacteria, viruses, protozoa, parasites present in water

Cons of Straw Portable Water Filters

  • The holes present in the membrane get clogged due to sediment, and bacteria over time
  • The screen is not very efficient to remover dissolved contaminants such as chlorine, heavy metals, and pharmaceuticals in water
2.Pump Portable Water Filters

First of all, it is essential to know that Pump filters are not extremely small, but they can also fit in a backpack easily without taking up too much space.

If you want to use the screen, you have to connect a lead line to the water source.

Connect another route to a water recipient.
You also have to use a small hand pump to draw the water.

Many pump filters rely on ceramic filters.
Some of them also use fibre filters, and some use one of these filtration techniques with the collaboration of an activated carbon filter or even a block activated carbon. 

However, the fibre filters work as same as the straw filter’s hollow membrane filters work.

They mechanically stop the contaminants from reaching your water.

However, ceramic filters also provide mechanical filtration, and these are also porous.

Their surfaces are covered in 0.5 – 1-micron holes. The water passes from these small holes and blocks all the contaminants.

One of the best advantages of using ceramic filters is that they can quickly stop the asbestos that is responsible for contaminating your water.

The most crucial thing that you have to keep in mind is, some bacteria are enough to pass through the ceramic filter and take place in your water.

Furthermore, the ceramic filter cannot stop organic compounds from contaminating your water.

For this purpose, some manufacturers use it with the combination of an activated carbon filter.

It has millions of microscopic pores between the carbon atoms.

It is fascinating to know that each gram of activated carbon presents a surface area of up to 2,000 square meters.

Pros of Pump Portable Water Filters

  • Pump filters improve the water’s smell and taste
  • An activated carbon filter has to be changed only once a year
  • All the essential minerals in the water are safe by this filter

Cons of Pump Portable Water Filters

  • This filter is a breeding ground for the trapped bacteria if it’s not changed in time
  • It is essential to know that pores in the carbon granules are astronomical and they cannot stop some bacteria species
3.Bottle Portable Water  Filters

Bottle filters have the great advantage of being useful when there is no other source to drink the water.

All you have to do is simply remove the filter cartridge and use it as an ordinary drinking bottle.

You can get safe and healthy water from any source of water.

When you have to drink water from the most contaminated source, then you can simply put in the filter cartridge and use your bottle as a filter.

However, the bottle filters rely on fibre filters to clean the water.

Some of the models of bottle filter also use solid block activated carbon filters instead.

The models of bottle filters that use fibre filters work the same as the straw filters, but there is no dipping of straw in a water source.

You are going to use a bottle as a recipient. In this way, the straw can filter out the contaminants and allow only clean water to reach.

However, the models that use an activated carbon block filter to clean the water also use a similar technology that works more precisely.

In this technique, the activated carbon is compressed to create a uniform matrix.

It will allow the activated carbon to absorb more contaminants and chemicals that reduce the size of their pores.

Hence, it makes it more efficient at trapping bacteria and parasites.

Pros of Bottle Portable Water Filters

  • Bottle filters have a great ability to reduce heavy metals like chromium, arsenic, and other contaminants in the water.
  • It can effectively block all the bacteria and viruses from reaching your drinking water
  • Bottle filter also allows beneficial minerals to remain in the water

Gravity water filters are best for campers, trekkers, and emergency peppers.

There is no need for any electricity or constant water supply to operate.

Gravity filters models are also perfect for those who like to travel in the areas where clean water is not available.

The water filters are made out of two containers placed above each other.

If you want to use these filters, you just have to pour water in the first container.

The gravity pull allows the water to passes through filter mediums and ends up in the other vessel that id placed lower.

However, the second container features a tap that you can use to refill your water recipient easily.

Gravity filters rely on the combination of ceramic and activated carbon filters.

These filters are beneficial to clean the water.
