But what does this mean exactly? How can you have access to clean whatever if the local water isn’t drinkable?

Good question. Well, there’s an answer for that. The Sawyer Mini Water Filter is your answer to clean water. This filtration device will ensure that you’re supplied with clean water so that you can travel with a worry-free mind.


The Sawyer Mini Water filter is designed to provide users with 0.1-micron absolute filtration. The guys over at Sawyer say that this process removes 99.99999% of all bacteria, including cholera, E.coli, salmonella and also removes 99.99999% of all protozoa, including cryptosporidium and giardia.

With this outstanding level of filtration, it’s an award-winning water filtration device which can filter up to 100,000 gallons of water. Let’s take a closer look at why the Sawyer Mini Water Filter is one of the best filtration systems on the market.

0.1 Micron Absolute Filtration

The water filter itself contains and a large number of small ‘U’ shaped hollow fiber micro-tubes which trap particles and allow the decontaminated water to filter through the system at a high flow rate. Through this system, it prevents water from storing, thus, reduces the chance of contamination.

The Sawyer Mini Water Filter is certified with 0.1 filtration, meaning that the pore size is not larger than 0.1 micron. With a pore size this small, the filter is reputed to be able to block bacteria such as salmonella, leptospirosis, E.coli, and Vibrio cholerae from passing through the filter.

With the filtration system, it’s passed the Environmental Protection Agency (EPA) recommended rates. You can read more about water filtation at the EPA.

100,000 Gallon filter

The Sawyer Mini Water Filter has a filter which is able to process 100,000 gallons of water. After use, you must backwash it with filtered water and the syringe that’s included with the filter.

The filtration systems membrane is strong enough to hold up against backwashing and restore up to 98.5% of the filter’s flow rate. The filter can be cleaned and reused without an expiration date as it can take up to 100,000 gallons.

By backwashing and sanitizing the filter, you don’t need to replace use disposable cartridges, saving you money and time.

Weight, Size & Build Materials

The Sawyer Mini Water Filter is the lightest and most versatile water filtration system that Sawyer produces. It only weighs 2 ounces and is able to fit directly in the palm of your hand.

This is essential, as you’ll be able to take it along with you on camping and backpacking trips without having to worry about it weighing you down. In addition, the size is perfect as it reduces the amount of space it takes up wherever it’s stored. It’s even small enough to fit into a sling bag like my patagonia atom sling that I recently reviewed.

It’s made with a hollow-fiber membrane which offers users a high flow rate when filtering the water. The water isn’t stored in the membrane which prevents the contamination of sitting water.

The filter membrane is a reusable pouch that you’ll also be able to use in a 16 fl. oz. Sawyer water filtration system as well. The syringe that comes with the filter is used to backflush the filter in order to maintain a high flow rate and prevent further contamination.

The size is 1 x 5 inches in dimensions which means it fits in the palm of your hand. So whether you’re backpacking or travelling overseas, you’ll be able to pack it in any size of backpack or suitcase. This is what’s great about the Sawyer Mini is that it’s compact in size so it doesn’t take a lot of effort to carry it with you.

You may be able to carry gallons of clean water with you and have the bottles stored in your car, however, it’s not convenient. In fact, it’s a huge hassle and takes up a lot of space in your vehicle – if you have one, that is. This is why the Sawyer Mini Water Filter is a necessity.

It provides you with the most basic need which is clean water. You no longer have to invest in gallons of water for your camping trip or having to boil water in order to clean it.
