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.
The bottom line The best-populated specification among the press bottles here, with a coarser pore figure than the rest and a hedge in front of it. Both facts are the maker’s, and both are worth reading.
What this listing puts on record
A 500 ml bottle, a hollow-fibre membrane with an activated carbon filter, a filtration accuracy of up to 0.2 µm, a cartridge capacity of 1500 L, a Selfpress mechanism the maker describes as a first of its kind, and an all-in-one construction stated to need no extra components.
Four columns filled
Volume, pore size, element type and cartridge life all appear. On this shelf that counts as a full sheet, and it is more than several listings here manage between them.
The two words in front of the pore size
Up to 0.2 µm. Two things are worth separating. The figure itself is the coarsest of the six filters here that publish one — three state 0.01 micron and two state 0.1 micron. And the phrase carries a hedge, which is the maker’s own and is reproduced rather than removed.
What the listing omits
Flow and weight. Ready within a few seconds is about getting the bottle working, not about how fast water moves through the element. No weight appears anywhere, and on a press bottle carried in a hand or a belt that is a figure people look for.
How the maker’s claims are written here
The bullets name bacteria, protozoa and other pathogens against a 99.99 % figure. That sentence belongs to the maker and keeps its author here: the maker states 99.99 % of bacteria, along with the other organisms it names. This page does not say what the filtered water may be used for. The maker’s instructions and the local authority wherever you fill are what govern that.
Before ordering
Half a litre is the number to think about before the microns. If your usual walk has one water source in it, a 500 ml press bottle is a refill point rather than a supply.

What it does well, and where it gives way
Strengths
Publishes four of the seven columns compared here — volume, pore size, element type and cartridge life
Names the element as a hollow-fibre membrane with activated carbon rather than leaving it as a filter
Stated as all-in-one with no additional components, which on this shelf means no syringe and no separate bag to lose
Compromises
The pore size is quoted as up to 0.2 µm, which is both the coarsest figure among the six here that give one and a phrase with a hedge built into it
No flow rate: ready in a few seconds describes assembly, not litres per minute
500 ml is a short carry, and no weight is published to set against it
Specifications
Micron rating
Up to 0.2 micron — stated as a filtration accuracy of up to 0.2 µm

Hollow-fibre membrane with an activated carbon filter — stated
Stated flow rate
Not published on the listing — the maker states it is ready to use within a few seconds, which describes setup rather than flow
Cartridge life
1500 litres — stated
Weight
Not published on the listing
Format
All-in-one press-through bottle of 500 ml, stated to need no additional components
Bottle thread compatibility
Not published on the listing — the element is part of the bottle, and no thread size is published

What people ask before buying
Does up to 0.2 micron mean 0.2 micron?
Up to is the maker’s wording and it is worth reading as written. A pore rating quoted with a hedge is a different claim from one quoted flat, and the difference is exactly why this hub prints the maker’s own phrasing rather than tidying it up.
What does all-in-one mean in practice?
That the maker states no additional components are needed — no separate housing, no bag, no syringe. Fewer parts is fewer things to lose, and it also means the element and the bottle are replaced as one system rather than separately.
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.
Foldable filter bottle · 750 ml · three-stage element · 200 litre cartridge · no pore size given
A rollable 750 ml filter bottle that publishes its volume and a 200 litre cartridge life, and gives no pore size at all — the shortest stated cartridge figure on this shelf with the least said about the element behind it.
Best for: Occasional use where the bottle folding flat matters more than the specification behind the element.
