Sawyer even forgives the mini version a "guarantee, 100,000 million gallons of" water filter. This corresponds to 378 540 l. You'd get along for 50 years with 20 liters a day, right? Who does not, only, the large filters 10 times as much - which can pay off in foreign missions in the Third World, in turn, for example, to leave him at the end kindly there, or humanitarian aid operations. Go this one is certainly due to the lighter weight the better choice. He also has a lot of optional accessories, the connection to a bucket / faucet for stationary use for the down time filtering, with this 540 l of the prescribed maximum amount daily. Can be connected to a pouch, which works well in my case it also with optional adapters. Here, too, I would revert to the small version, as big - in my case, at least - the handling does not make just pleasant.
A pre-filter, possibly nylon o. Ä. Should be already used in roughly verschutztem water, and as it does not filter viruses, should when traveling in hot countries that viral pathogens may contain in the water, where again may survive parasitically viruses, about a dual solution with boiling / chem. Filtering be considered. If the taste of the water to be positively influenced / needs can also be a carbon pre-filter be tinkered, instructions, can be found manifold in the net.
The cleaning is done with the cleaning syringe with clean several times (on the go: already filtered) water are pressed in the direction opposite to the direction filter through the filter. However, this is necessary only after a few days or for very unclean water. On the way you can save the weight of the syringe, and replace it with a smaller syringe or with the big filter through a bottle with a matching cap or Platypus o. Ä.. This works beautifully. For hygiene reasons we can b. Bed. In common use then switch to cups for drinking. The handling is easy, the water flows very fast and has so far been properly. For longer storage, z. B. for wintering, he should present a number of times, for example, dissolved in warm water soda, and be nachgepült with water itself. Otherwise, it does not require maintenance.
The formerly used Kathadyn filter has been replaced in the long run against this here.
This one is absolutely in my opinion, best product on the market, and should really find space due to its compact dimensions in each pocket. Only the beiligende bottle should be replaced before you realize on tour that it was a bad joke. Beyond the above-mentioned Platypus (folding) bottle or with a similar essay for the large version, for this here every X Any replace him. I will pull no point because the product is great, and the bottle only an optional addition which is a freebie from the manufacturer, no part of the system. The filter here is anyway very cheap available and incredibly well compared to everything else.
