The portable water filter you select will be driven by your primary intended use

If you want a compact water filter perfect for hiking, backpacking, and trekking, a water filter straw will be the way to go. If you are on the road in a camper or RV a countertop portable water filter may be the tool for you. 

Additionally, you need to check the efficiency of your new filter. 

If you are going to use your filter when you’re out camping, then you need to make sure that it can remove as much bacteria as possible, as natural sources of water tend to be contain more harmful bacteria and parasites. 

There are four main types: straw filters, pump filters, squeeze filters, and gravity filters, but UV filters are becoming more and more popular. 

They each have their own pros and cons and are best suited for certain situations. Gravity filters, for example, aren’t great for getting water from shallow sources, but can easily filter a lot at once. 

On the other hand, straw filters are light and compact and can be used with almost any water source.

Portable Water Filter Benefits

I love having a portable water filter because it means that I have access to clean water when I’m on the go. 

I backpack as often as possible and have used many portable water filters over the years.

A high quality water filter does a great job at removing particles and sediment from the water and can even filter out some chemicals and contaminants. 

While I believe in preparing for a grid down situation, which is one great reason to have a portable water filter, I also like having one on hand when I’m camping or out in the woods.

These handy filters are very versatile. 

With a portable water filter you won’t ever have to worry about whether or not you will have access to clean drinking water.

What to Look For

When making your selection always check out the sieve size. 

This is usually labeled with the micron size of the filter. 

Survival grade filters are going to have much smaller pores in the sieves, which will help them to easily filter out more contaminants. 

The maximum sieve pore size you should get is 0.2 microns so you can easily sieve out most contaminants.

You also need to consider how much water your filter is rated to handle. 

This will affect how often you use your filter, as well as how long it will last. 

When you choose a filter that is rated up to a higher amount of gallons, then you won’t have to worry about it failing you when you’re out in the woods.

How to Best Use Your New Portable Water Filter

It’s important that you use your water filter correctly so that you don’t accidentally ingest any contaminated water. 

While these water filters are all fairly easy to use, I recommend reading the instructions on your new portable water filter to ensure proper filtration.

That being said, I believe that any time you are concerned with the quality of your water, you need to make sure that you use your new portable water filter. 

This will help you to filter out contaminants. Even if the water looks clear, there can be pollutants or bacteria in the water that can make you sick.


Make sure to only select your portable water filter from a reputable source. 

When dealing with water quality, this isn’t a place to go cheap.

It’s also very important that you make sure to replace your portable water filter when it has filtered its set amount of gallons. 

Failing to do so will cause your water filter to not work the way that it should, which can put you in danger of drinking contaminated water.
