Need Lightweight Water Filter for Backpacking

I want to upgrade my old dinosaur. Any suggestions? Thanks!

I have partner who uses the MSR HyperFlow Microfilter. Very light and fast: https://www.msrgear.com/water/hyperflow-microfilter. The pore size is 0.2 (0.45 is what microbiologists use to capture bacteria), so it is plenty small enough to filter out protozoa and bacteria. If you are planning on using this abroad, I would add a chlorine dioxide tablet or drops to deactivate virus particles.

I use a Sawyer mini filter: https://sawyer.com/products/sawyer-mini-filter/.

What's your dinosaur and what about it would you like to improve?

My dinosaur is a Katadyn Hiker - similar to the MSR Hyperflow. MSR claims a much faster flow rate for theirs, but that's not enough for me to spend money on an upgrade. I usually pump a liter or two at a time, which takes me one or two minutes. Cutting that to ten or twenty seconds wouldn't improve my quality of hiking.

I just got a Katadyn BeFree water filter. It's a squeeze filter like the sawyer, but WAY faster and the bag is soft rather than rigid. I used a sawyer last year which was great, super light weight and all, but it's flow is pretty slow and takes a lot of squeezing. I've used the BeFree twice in the field now and I love it. Certainly worth looking in to.

I have an old MSR. I believe the model name is "airspring accumulator." It works fine and has served me well. I'm looking for something ultralight. I'm not worried about saving 20 seconds in the backcountry, LOL.

I want to hear some real world reviews on the MSR TrailShot. You should buy one!

I don't use one. It's the lightest option I've found.

Makes it so you are less likely to carry the water as well so it saves more than just a few ounces.

You are quite a rare American. The rest are minions, so if they say don't drink the awesomely fresh clean cold superiorly filtered water that basically flows straight out of the mountain because it will make you sick, then they are not going to drink it.

The lightest weight option is the tablets btw.

Lol, If you travel overseas the water is likely to get better, you will find that most bar the odd few mountainous regions on the planet are in a far more pristine condition than the USA regions.

Giardia isn't something to fear, I have had it. If it is your time to get it you will get it. Most likely from some place like at home or from bottled water, because unless you have some sort of mega weakness in your immune system or are a little light headed and get water from a swamp or some other no Brainer place then you will be fine.

LOL, I'm the last person you need to lecture about Giardia spp. I did my graduate research and dissertation on waterborne pathogens, including Giardia spp., one of only three researchers in the U.S. pursuing that line of research at the time. I worked as a water quality scientist at a pioneering laboratories and agencies in water quality in the United States.

I mention chlorine dioxide specifically for virus particles. Protozoans are large and easy to filter out. The one time I became ill from drinking untreated water was due to a virus. Giardia is all but non existent in municipal drinking water supplies in the U.S., bottled water ditto. Bacteria are a big concern in bottled water, however.

This is true... people do not think for themselves. I have encountered people filtering water that literally is coming from a spring right out of the ground. Better safe than sorry he said. I told him to filter what comes out of the faucet then because that has more bacteria than whatever was coming out of that mountain. He eventually got tired and stopped filtering.

Yes tablets lightest. If I am in an area with cows I have taken tablets and they work fine and weigh nothing.

FWIW, I am very careful about where I get my water. If it is literally melting off a snow bank, then I do not disinfect it. Streams, lakes, etc., I use chlorine dioxide tablets. The ONE time I became sick was when I was drinking snow melt that had collected in a small rock basin. It had just snowed, then melted, so it had to be fine so I thought, so I did not treat it. As I drank, I looked over and then saw mice bathing in the water. I was sick for months, had every test done and the doc concluded it was some kind of virus.
