Choosing The Right Water Filter

Well, you may make the point that okay, you’ve given us the top 10, well and good, but now how do we choose which is the right one for us on our next trip?

Here are a few factors to consider while shortlisting which one to go for.

Brand

Choosing a product offered by an established brand is always a bonus.

Katadyn, MSR, and LifeStraw have been in the water filtering business for many decades now and have established a reputation for themselves.

Going for these brands would mean assured quality and accountability.

However, let that not deter you from trying out some of the lesser-known products that are trying to make a name for themselves.

Water Availability

If the availability of water is scarce in the region where you plan to head out/camp, then definitely you must give importance to the storage component of the water filter.

Higher the storage, more water for you!

Water Purification Method

Well, if you’re journeying into a place where the water sources may not be all that clean or hygienic, then the technology used for filtering/purification of water comes into the picture.

You would want to choose the product having the best filter that can destroy microbes of minuscule sizes.

The carbon fiber activated carbon technology along with the filter pore size are some of the parameters that you might want to check up on before going in for the purchase.

Nature of Travel

If you’re going camping or some recreational outdoor activity then the size or weight of the water filter will not be of much concern.

But if you’re a military man or going into extreme terrain (mountaineering or trekking) you will need to lessen your load as much as possible.

It is due to this reason that it will be ideal to choose a water filter that is lightweight and travels handy.

Also, pick a sturdily built product to ensure its longevity and successful use throughout your expedition.

Final Thoughts

We feel there is a very diverse collection of military water filters available in the market today and since it is an upcoming sector, there is heavy competition among the brands.

The 10 best military water filters out there are listed above, some have the edge in portability while others in water purification methods.

But all the products meet the industry standard in water filtering, and choosing between them is purely based on your specific need and where you plan to go.

Also affecting your choice will be the geographic factors, water availability in the region, etc.

that you must remember to consider while picking a water filter.

I believe there are other lesser-known options available but these are the reliable ones and when it comes to pure water, above all else, purity and reliability are of paramount importance!
