Steri pens don't filter the water, they disinfect the water. My recommendation is for the Sweetwater filter, I have one and I like it. It is relatively lightweight, relatively easy to pump, and is effective as any of the other offerings. FWIW, my background is in water quality science and I did my graduate school dissertation on waterborne pathogens.

It does not endorse any one product but presents information on the methods available and the pros/cons/limitations of each method.

Turns out, I'm not super crazy about it for our purposes. Doing some of the mountain hike/climbs in the Sierra means I'm drinking quite a bit of water throughout the day, ideally.

To fill up our large camel Baks takes three 1-liter bottles, which is the Steripen's 90 sec stir. For me and my wife, that means we have to do 6 of those everytime we want to fill up. It starts to sound easier to just get one of the new high-efficiency light-weight pumps.

Also, we have a hard time seeing the lights in the bright sunshine, which sometiems makes one wonder if they even really filtered the water.

That said, I do really like that it kills viruses too. It's lightweight, compact. And, if you just want 1-2 liters, really easy.

I'll probably get a light-weight pump too, and take one, or the other, depending on the type of trip.

Type of trip is important, as well as number of people being hydrated with it. Steripens are ideal for water with fewer particulates, fast and light trips, and good for getting a quick liter or two of water. Trying to disinfect water for a group, with only one pen, is not efficient. Steripen is just another tool for certain people and certain applications.....definitely not a one size fits all solution!

Once again not a filter but I loved using the Camelbak All clear. so simple to use and I could recharge with a built in USB port. Found it really handy when there was any source of flowing water. Of course wasnt so good, if water was uber shitty and then I just tried to filter through a buff.

Very much agreed. The Steripen will be great still for certain trips, like you mention. Not sorry I bought it - just a lil bummed it didn't work out as well for certain trips.

Has anybody had experience with these:

From what I can gather, they pump fast and are very light. Sounds like the downside is they clog easy.

I've used Steripen several years and long as the water is clear (can't be muddy or floculant), it does the trick. On sunny days, I will take the surface water off of lakes above 10,500 feet without any treatment as the water is already radiated by the sun's UV.
