SURVIVO in-line filter for PET threads and reservoirs, 0.01 micron stated review
The one filter on this shelf that treats compatibility as a specification: a standardised PET bottle thread and a stated connection to hydration reservoirs, alongside a 0.01 micron pore size and a 4000 litre cartridge life.
The bottom line The specification sheet this family should be writing: pore size, cartridge life, element type and compatibility, all stated. Only the flow and the weight are missing.
What this listing puts on record
A 0.01 micron ultrafiltration membrane combined with activated carbon, a cartridge life of up to 4000 L, a standardised thread stated to fit commercially available PET bottles, and a stated connection to water bags and drinking systems.
The compatibility line, published for once
Eight of the nine filters in this family describe screwing onto a bottle without saying which. This one names a standardised PET thread and states that it also connects to reservoirs and drinking systems. That is the difference between a filter you can plan around and a filter you find out about when it arrives.
What is still missing is the number. Standardised is a claim about a convention, not a diameter, and if you are matching a soft flask or a particular reservoir fitting it is worth putting the question to the maker first.
The two comparison figures
Both are here and both are repeated: 0.01 micron and 4000 litres. Repetition matters more than it sounds — a figure that appears once in a title and never again is often a figure nobody checked.
How the maker’s claims are written here
The bullets put a 99.99 % figure against bacteria and pathogens. On this site that sentence keeps its author: the maker states 99.99 % of bacteria. Nothing on this page says what the water coming out of the filter may be used for; the maker’s own instructions and the authority local to where you fill are what govern that.
Before ordering
Take the fitting you intend to use it with — the neck of your bottle, or the hose on your reservoir — and put the question to the maker before the parcel arrives. The thread is described here better than anywhere else on the shelf, and it is still not a dimension.
Availability
Selling at about 30 € on the German Amazon store when this page was checked.
Catalogued on the French, Italian and Spanish Amazon stores with nobody selling it: the reference is there, the offer is not.
Nothing came back from the American and British Amazon stores, so the buy link there opens a local search instead of a page that is not there.

What it does well, and where it gives way
Strengths
The only listing on this shelf to make compatibility explicit: a standardised PET thread, and a stated connection to reservoirs and drinking systems
Publishes a 0.01 micron pore size and a 4000 litre cartridge life together, and repeats both rather than mentioning them once
Names the element as activated carbon with an ultrafiltration membrane instead of leaving the type open
Compromises
Standardised is not a number: the thread is described but never given in millimetres
No flow rate, which matters on an in-line filter where the draw runs through a hose
No weight, on a part that is bought to sit in a hydration line

What people ask before buying
What does in-line mean here?
That the filter sits between the water and your mouth on an existing system — screwed to a PET bottle or spliced into a reservoir hose — rather than being a bottle of its own. It is the format that adds the least to a pack you have already built.
Is a standardised thread enough to go on?
It is more than the rest of this shelf publishes, and it is still a word rather than a measurement. PET necks are broadly consistent, but soft flasks and reservoir fittings are not, so the connection you actually intend to make is worth checking against the maker before ordering.
Press filter bottle · 500 ml · 0.2 micron stated · hollow fibre with carbon · 1500 litre cartridge
A 500 ml press bottle that publishes volume, pore size, element type and cartridge life — four of the seven columns this hub compares — and quotes the coarsest micron figure of the six filters here that give one.
Best for: A short walk or a run where one small bottle refilled at the stream is the whole water plan.
Filter and bottle set · 0.1 micron stated · hollow-fibre membrane · 4000 litre cartridge · 0.5 L bottle
A hollow-fibre filter sold with the bottle it screws onto, publishing both a 0.1 micron pore size and a 4000 litre cartridge life — and, because the bottle comes in the box, never needing to say what thread the filter takes.
Best for: A day walk where the water is refilled often and the whole set can live in a hip pocket.
Press bottle · 710 ml · 250 litre replaceable cartridge · no pore size published
A 710 ml press bottle with a replaceable cartridge rated at 250 litres, and the most talkative claim list on this shelf — every one of which is written here as the maker’s claim, because no pore size is published to check any of it against.
Best for: Travel where one bottle is treated at a time and the cartridge is expected to be replaced as a routine cost.
