    My Neoair is getting some rather grotty-looking mould inside it - and has for a few years. It's a 2013 model, used quite a bit. Anyone else had the same? Any suggestions on how to remove it - or prevent it getting worse? My wife's one is going the same way, a 2015 model.
    Thanks,
    Rob

    General rule seems to be to limit how much moisture gets in there, use pump/pumpsack rather than breath.

    Mine is the same, looks a bit manky - has anyone actually determined whether this actually causes a meaningful loss of performance?

    I just avoid holding it up to the light :)

    If its still damp in there then drying it out might prevent things worsening. I've tried a cycle of inflate with pump sac, place near radiator for half an hour, deflate, repeat a few times, which I hoped was drying the inside, though I can't be sure. Perhaps some careful weighing might provide confirmation... I can't really think its feasible to get a fungicide in there.

    I just try not to think about it. Mine must be at least 6 years old, and only ever inflated au naturelle. It's probably a bacteriologist's paradise in there.

    Back home after use, I give it a wipe down, then hang it on the washing line slightly inflated with the valve undone for a while.

    Akin to @Patrick 's approach inflating and deflating several times using clean (dry) air? Might that help disperse the moist/manky stuff? Better still, might there be some kind of harmless gaseous sterilising product which could be introduced at the same time?

    This is my care routine for my Exped inflatable mats - every time I get home.
    Several years on and I haven't detected any mould in any of them.

    Hi all, thanks v much for the helpful replies. Sorry mine is a bit late, been away and horribly busy. The approaches sound sensible, albeit a bit time consuming? How long does it take? Can one connect a pump sac to a NeoAir? Any recommendations?
    Mould and mankiness apart, I do feel the NeoAir is a good bit of kit.
    Thanks again,
    Rob

    I use an Exped Snozzle to inflate my Thermarest Uberlight. It's tight, but it does fit and prevents any mould issues.

    Unless you breathe in the air from the mat, I can’t see it is a problem. Even then, the mould presumably comes from the air from your lungs. You could rinse it out in theory. Milton fluid would probably be the safest to use. I’ve been using the little Thermarest battery pump on my full length X-Lite and there doesn’t appear to any mould in that. My short X-Lite has mould from inflating by mouth. It’s a subject that has popped up on various forums over the years.

    I'm not sure I'd rinse it out - I think it would be really hard to get the inside properly dry again. I've made a few "pump sacs" for my neoairs using a little bit of garden hose with some of the internal laminate stripped out, simply taped into the bottom of a supermarket carrier bag. Works very well, actually. And its very light :D

    Easy to make an inflation bag for a NeoAir using the top section of a wide mouthed pop bottle and a rubber grommet. Add a bin liner and away you go. :)

    I've used the xtherm pump bag to inflate mine, but then give it a couple of breaths to finish it off. I can already see a couple of droplets inside, so thin they are very visible.

    Hi all,
    Many thanks for the replies. Apologies for the slow reply, I wasn't getting notifications and have only just seen them. The electric pump and pumpsac look useful - could use the latter as a drybag. The DIY ones look neat too. People here are so innovative! And helpful too.

    I use the pump bag and it also doubles as a dry sack. With a big hole in it to go over the nozzle:oops:...

    So not very dry really.

    They miss a trick there, my klymit lwd pump sack has a plug, seems to work well.

    Would the Klymit fit the Neoair?

    Na, prob a bit heavier too, but very effective. Revelation to me was learning to gently blow into the pumpsack as you close it, makes a hug difference to how much air you get in there.

    As people have said above and nearly free. My large Xlite takes 3 (Nylofume) bags. No effort whatsover. Been doing this for ages with a Nylofume bag.

    The Vaude pump sack is good, seals much better round the valve than the NeoAir pump sac, and doubles as a dry bag for sleeping bag etc. I marginally prefer it to the NeoAir battery powered mini pump as it requires less 'topping up' with breath to reach full inhalation.

    Any moisture droplets in the Uberlite really show through the fabric, and even when only topping up the inflation with breath I've got moisture droplets inside. Just as well you can't see inside my 10-year old NeoAir, which was inflated by breath exclusively for the first few years...
