You are spot on. Also covering the mouth of the container with a bandana is a big bonus too

Awesome tip ! Thank you

Is food grade silicone another toxin? Won't it saturate the filter?

Thanks Mike. It's nice to talk to end users on the daily. Best way to keep improving something

Thanks Eugenio 🤜🏼🔥🤛🏼 / joe

Very welcome ! 🤜🏼🤛🏼

Your very welcome. Anything at all to help take those bits out is worth it. If it still gets hard to use after that I recommend returning the filter.

Thank you. Sadly, we had to stop selling on our site. Just a lack of time to be able to make sure it all ran smoothly. You can find them at the bushcraft store in the UK or camp craft outdoors, stateside. If that helps

They sell them on Etsy

@@curttomlinson9337thanks for the pointer. My Grayl arrived today and I just ordered the millbank bag off etsy!

Agreed. I think people should draw the distinction between water on the move and stationary water. Things like having time to boil when you set up camp or a big filter at a Bug out location. The grayl sits perfectly in the water on the moves section

Getting sick of dirty water is defin. an issue and replacing the filter is the best solution. Do you think that flushing the Grayl with diluted H2O2 after use and back at home, just to get rid of residual bacteria an prototozoe could be effektive? Do you additionally boil filtered water out of a used Grayl? Would be nice to hear from you, thanks.

Thank you Corley !

All the best brother 🤜🏼🔥🤛🏼

A great question, and I ain't a spokesperson for grayl. I live in sweden, and the temps get pretty vicious. But I have a thick wool cozy for my one. In the viciously colder months (-30c) just strain and boil.

Thanks my friend 🤜🏼🔥🤛🏼

❤ I never thought of that.

A very good tip brother. I use sawyer a heap in the car and such. But as you can imagine this is a commissioned video by grayl.

The sawyer is also much better against cysts and Protozoa than the Grayl

@@seankelleher4222 yes but its ability for microplastics, heavy metals and blood born pathogens etc. is what does it for me. I dont agree there is one filter to rule them all. But there is horses for courses and when I am UL hiking in mountains the sawyer works just fine. For everything else I use the grayl.

@@inforestsandlands it does depend on what the risks are. 3 log removal of cysts and protozoa is inadequate in any source where they are a significant risk. And the amount of things like heavy metal that the Grayl will actually deal with is very uncertain. It’s main advantage is where viruses are a risk - but they can be dealt with by temperature pasturisation. It’s biggest problem though is that there is no genuine way of knowing when that cartridge has run out of umph.

Great question and yes that is entirely possible. As always be careful of any bottle containing boiling water as seals can always go. As I have seen too many times haha

If your filter has the anti backflow silicon insert in it, it should be possible to remove it. Then fill clean cup with clean water while inserted and withdraw out from cup. Might take a few draws, but should backflush grayl if at all possible. Haven't tried it yet. Simple enough principle. The one point however is I normally replace my carbon filters every 9-12 mths. with average use. Irregardless of ceramic filter conditions. Am a zon just had geofilters on sale $23.00 so I picked up couple. I use Millbank bags and have a dozen various sawyer type/form filters which I add bag/tubing/refillable charcoal-filter canister to. The Grayl is good for instant right now water supply. The bag system is a good camp/long term supply system where you have time to set up and treat water supply in volume.

To my knowledge there is no functional difference. The black models were simply made for people who bought the covert edition Geopress and didn't want the aesthetic ruined with a bright orange filter.

Just the color. I use them to help prevent mixing up new vs old filters.

Just the same. It's more about what the various stages of the filter can handle or remove. Legally that's what can be said to he 99.99.99 percent safe.

Wash with warm soapy water, by hand only, the container and never wash in any way the cartridge itself, the cartridge cannot be cleaned.

The filter can be rinsed well had set out to dry in a warm place for 3-4 days for long term storage between uses. Always chech visually and smell rest for mold/mildew growth. Thats why a warm area with air flow is best, avoid cold, stagnent air and high humidity when drying.

Of course, brother. Its the Savotta water bucket.

@@inforestsandlands perfect, thank you for quick reply. Keep up with your content, I really enjoy learning from your videos.

Let it dry out. Thoroughly dry cartridge by performing 1-2 'dry presses' (pressing without any water in the bottle) and empty excess water. Remove cartridge and allow it to air dry completely (depending on humidity it can take 2 - 4 days). Hand wash all other parts with warm, soapy water. Reassemble Grayl filter to create air tight seal for storage. Cartridges can last up to 3 years after opening if cared for properly between uses.

There are instructions with it that say you should dry it out for 1-4 days.

?????

No problem. Are you stateside or Europe?

Backflushing a Grayl may or may not be a great idea. It’s not designed for it. And even if it does unclog it a bit without damage it isn’t doing anything to restore the active carbon so may just be giving a false sense of security.

@@seankelleher4222 Have you ever replaced the filter? Asking for signs of degregation. I have a replacement but the original seems to do fine, despite the heavy use. I’ve relied on it now coming half-year.

@ it’s impossible to tell when the activated carbon is exhausted. That’s an intrinsic problem with activated carbon based systems. That’s why Grayl say to replace the cartridge after x many litres. If it’s been used heavily for 6 months it’s probably all used up and no longer removing pathogens.

@@seankelleher4222 Manufacturer website “An UltraPress cartridge is rated for ~300 cycles (150 liters / 40 gallons); GeoPress cartridge for ~350 (250 liters / 65 gallons)” I’m around 70 gallons minimum. Time to exchange the filter and keep an eye on the volume. Good timing, thanks.

Variose types of collapsable buckets availible online, standard sources. They go back to marine canvas buckets, but now use more modern designs and materials. And their fairly cheap and compact.

If your based in Europe you can buy them from Astro Sweden , Scandinavian outdoors and Friluftsland. Amazon do also have them from time to time.

@@inforestsandlands Thank you! I could not find them anywhere!

Best way to do it

haha " i should call her"
