The standard BottlePro refill is brilliant for everyday tap water. But if you're travelling abroad, hiking, or anywhere you can't vouch for the water supply, you need the Ahlstrom refill.
Originally developed by the Argonide Corporation for NASA space exploration, Ahlstrom Disruptor technology works differently to a conventional carbon filter. Rather than mechanically blocking contaminants by pore size, it removes submicron particles through electroadhesion and ion exchange — meaning it can tackle bacteria, viruses, and pathogens that a standard filter simply can't catch. The result is 99.99% pathogen removal, making it suitable for water sources that would otherwise be undrinkable.
If you're heading somewhere with uncertain water quality — parts of Asia, Latin America, Africa, or remote areas — this is the refill you want in your bottle.
What the Ahlstrom refill removes
- 99.99% of bacteria and viruses
- Submicron particulates
- Heavy metals
- Organic acids
- Chlorine and chemical contaminants
- Cysts and cell debris
- Trace pharmaceuticals
- 80+ substances in total
How to change the cartridge
- Unscrew the cap from the BottlePro bottle
- Unscrew the inner piece that connects the refill to the straw
- Unscrew the old refill and insert the new Ahlstrom cartridge
- Rinse under running water for 30–60 seconds before first use
- Fill from your water source, drink through the straw
Note: due to the smaller pore size of Ahlstrom technology, the flow rate is slightly lower than the standard refill — a little more suction is normal.
