    Anyone know if UK Smart bottles, and Evernew or Platypus bladders are compatible with BeFree filter tops?

    Not much info online except BPL, apparently they work on Hydrapak which make the BeFree soft bottles. The opening is 23mm ish...

    Or any other reusable supermarket bought water or juice bottles?

    Threads are 42mm. ive not found any supermarket bottles in a good enough size yet. I carry the 1L bag it came with and a 3L hydrapak seeker.

    Thanks @paul - I thought 23mm sounded a bit narrow for the size of it.

    I think even if there was a couple of 500m bottles that fit it would work for me. I wonder if Source Convertube adaptors would help

    some of the lucozade wide top bottles might fit but ive not got to testing them yet.

    I have recently bought one of these. It has such a fast flow rate that I intend to use the the 1l bag it comes with as my sole dirty bottle and just fill up my normal bottles from it while at source. Why do you want to attach it to another bottle?

    Was considering using it on 500-750ml bottles in a strap bottle holster rather than bottle filling . I prefer semi solid bottles in holsters to soft bottles.

    Something like these might work...all were 750ml

    On one of the more recent Mittencamper videos he's complaining that no matter how he cleans his Befree its flow rate reduces to clogged mini rate. He might be a little impatient though.

    Sorry to go off topic, but how do you "tag" someone in a thread, e.g. as PaulB has just tagged me with the @ in front of the name? I tried "copy" over the name of the person on their profile pic but when I pasted it, it arrived without the @ and when I typed in an @ it came out a different colour and not linked to the name. There must be another way.

    And can tags have wide mouths that fit a Katadyn befree?

    Just type @, then at least the first 3 letters of the user, then click the username that comes up in the pop-up. :)

    Nope.
    They are generally 37mm, not 42mm

    (from right to left, 27mm, 37mm, 42mm and 55mm)
    BTW
    The BeFree filter uses a standard 27mm cap on the outlet side.

    You might have an issue with the bottle collapsing, air will not backflow through the filter, so to reinflate you'll need to unscrew the filter to let air back in.
    The Hydrapak stash is semi solid (the two ends are solid, but the walls are collapsible.

    The 42mm cap is pretty rare, the only other bottle I've found with it is some of the Nalgene bottles, but as they are solid, they are no good.

    Anyone used the BeFree a LOT, like weeks?

    Juggling longevity over flexibility for the Sierra?

    The Sawyer is the logical choice, but the flow rate of the BeFree is great.

    Also thanks Ken. I was on the verge of buying a Katadyn, but this has made me think again. I draw much of my water from tarns, and it contains a relatively high proportion of suspended matter.

    Like others, I was getting a little tired of the Sawyer Mini's flow rate, but at least it's reliable. As long as you take the backflushing syringe in your pack as well, that is. Originally I would leave this behind, thinking I could just backflush between trips, to save 32g. This summer, however, I had virtually no flow by day 3 of a hike so learned my lesson! Thereafter I took it, and I was surprised to see just how much gunge was expelled on the initial backflush when used during the hike.

    I'm therefore satisfied that on anything more than a simple day hike for one person (when weight's not such an issue anyway), the backflushing syringe must be carried, which raises the true (dry) weight of the Sawyer Mini from 40g to 72g.

    It takes me 15-20 minutes faffing to filter the 'evening supply', which in my case means filling a 2L platypus bottle (dinner, breakfast, and associated drinks) plus another litre bottle for 'extras'. Not brilliant, but when you remind yourself of what the system actually enables, it's pretty amazing.

    @dovidola
    There are a number of ways to cut the faff;

    Don't bother with the syringe...a bottle top with a Sawyer sized hole in it turns your water bottle into a backflusher.
    Trap some fine woven cloth between the Sawyer and the supply, makes an effective pre-filter for turbid water. Parachute nylon is great. Roll up disposable ciggy filters can also work well.
    Filter on demand.
    Gravity filter.
    Boil turbid water....you can boil 3-4 litres of doggy froggy boggy filter clogging water for the syringe weight in fuel.
    For bladder systems, a paper inline petrol filter keeps the Sawyer rocking a good flow for weeks without attention for less then the syringe weight

    Doing all this, I've once chosen to backflush in the field since switching to Sawyer inlines from Aquagurad and that's in many hundreds of nights out. I still carry a bottle cap with a hole, and a strip of treatment tabs in the FAK just in case of failure.

    Thanks @Teepee I was going to ask if there was a lighter DIY option than the supplied syringe. So all I need do is cut a hole in a bottle cap, the hole being a compatible diameter with the Sawyer's nozzle, then put that cap on a squeezy bottle (like my platypus) of clean water, then squeeze water back through the filter to backflush? Will that provide as much flushing force as the syringe?

    Agreed it makes sense to carry a strip of backup tabs (mine also live in the FAK).

    I’ve read the BPL thread about the Katadyn BeFree and the problem is silty water or with too much organic matter that is blocking the filter. So, presumably if I made a little parachute nylon sock that slips over the BeFree plastic cage, perhaps held in place with a line of silicone gel on the inner surface, or elastic, then the Teepee pre-filter method for the sawyer would also save the BeFree from blocking?

    Before I get my sewing machine out, have I understood this correctly?

    @dovidola It's just enough, takes a little more effort but it works. It good to get the hole just big enough and with a thick screwcap so you can give it some 'welly'. TBH, I find the syringe pretty average at best and struggle to clear debris with it. Like Rich, I use a tap adaptor and blast it with mains pressure....doing that into a clear glass I can see the extra debris that it's cleared in comparison. I only use the syringe for the bleach and store part.

    @Clare , you could be onto something very good there. Yes, a little sock could be just the ticket. Traditionally, finely woven cotton is used (see Millbank bag), but I found parachute Nylon to be good when I first used a stuff sack to filter out a load of suspended algae.

    Maybe a calandered downproof fabric would be a good try? you can get really fine mesh from ebay for fuel filtration, a microfibre lens cloth.... just maybe a coffee filter could work?

    Useful thread!
    There is a water sports bottle top that matches the Sawyer for flushing, can't remember which ATM.
