    Took some adjustment, but it works well

    • Familiarity: I've put it through the wringer

    After spending $100 on my steripen ultra, I didnt want to dish out too much on filtering out particulates. Being in heavily polluted parts of appalachia, I tend to be pretty picky with my water sources, and sometimes standing water is actually a better option. The filter didnt fit over the lip of my water bottle, so I ended up turning utilizing a two stage system to avoid getting untreated water on the lip. I collect the water in a collapsible bottle and then pour that through the filter cone to avoid cross-contamination. It might be a bit bulky and inefficient, but Im not trying to be sexy when treating water in the back country. Its effective, light-weight, inexpensive, and I havnt gotten sick. Pretty much exactly what I was looking for.

    Could be better

    • Familiarity: I've used it several times

    So basically I use this and iodine tabs to get my water on the trail, this does a nice job of filtering out any pieces from the water. The screen flows rather slow though, and it the cone does not fit all that well into the Platypus brand water bottles (if you can call those bottles). The two pieces of the cone are hard to get together.

    My son has one too, and he uses the Steri-Pen with it in a Nalgene bottle and it fits tight in the bottle and the pen fits tight in the cone.

    Overall, it could be better, but it does the job and it takes up only a small amount of room in a pack.

    Must Have

    • Familiarity: I've put it through the wringer

    Its a must have for filtering water with any kind of debris in it. My only pet peeve, is that I wish they made it more compact and lighter. The rubber/plastic is kind of bulky. I've seen others trim it down for the trail.

    A great companion to SteriPEN

      ok, so we all know the limitations of SteriPEN, the major one being that it's weak against murky/cloudy water. so assuming you've conceded to the fact, for the purposes of treating "clear" water, this is a great companion to the SteriPEN. Because most "clear" water source in nature will have some visual sediments that you'd rather not consume. The FitsAll does exactly that of removing those visible "ants." But don't go thinking that this will solve the issue of turbid water. One thing to note when using this is to ensure you're pouring around the push tab (also make sure the push tab is pulled open) and not through the hole/opening of the push tab as the water that goes through it won't get filtered through the filter screen.

      A great companion to SteriPEN

      Okay for large particulates, but almost pointless

        As I said it is great for large particulate matter, but doesn't really clear up the turbidity even after multiple filters. For its limited application it works rather well; however, after melting down 3.5 liters worth of snow in Yosemite, filtering it all twice, we were still left with slightly turbid and gritty water. I gave it three stars only because it does work, albeit in a limited capacity.

        Good product, but I don't use it

          I don't want to talk bad about the product because it does what it claims to do and does it well. My only thing is that the places I have been, I could use a bandana instead which is lighter and I carry anyway. Dual purpose gear is great when you are trying to go light. With this, it just takes up space and weight I wouldn't otherwise need. That being said, if I go someplace and I am unfamiliar with the water quality, I would probably throw this in my bag.

          Good add on for Steripen users

            Yeah, you could use a bandanna to pre-filter smut from the water. However, there is a feature on this that ROCKS. You can completely immerse a bottle with the pre-filter intact, open the little air valve, and fill quickly under water. You can also pour water into it for filtering, if you prefer to do it that way.

            Quick tip, which Hydro Photon included in their directions. If you put water in it, and it doesn't seem to be filtering through, make sure to pre-wet the filter and give the surface of it a rub with your fingers to fully saturate it. Then it will start passing water.

            The mesh is so fine it holds water when dry. At least I found that to be the case. This mates up perfectly with a Gatorade bottle, which is my preferred bottle. You could also do soda/water bottles with the funnel attached.

            Can you completely immerse it? I thought that you need to make sure that the water doesn't go through the hole in the air valve/pop up thing in the middle.

            I'm thinking you might be able to dip it into the water and allow water to spill over the edges as long as you kept the air valve out of the water. I don't own one of these yet.
