M: I’ve just found the most useful device at the new outdoor store — a water purifier.
W: A water purifier? You want to carry even more equipment with you on our hiking trip?
M: If it’s light in weight and gave work, yes! And this one fits that description.
W: Really? I’d bet it takes up a lot of room.
M: Not at all. It’s a straw, much like the one you use to drink a soda water or a milkshake.
W: Really? That is small.
M: Yeah, it’s plastic and has a series of mineral and chemical filters that strains harmful microbes from water.
W: It’s fantastic, but can it filter the germs out of the stagnant pond water or water from lakes and streams?
M: Yes,[20]it makes the water entirely germfree.
W: But what about salt or chemical pollutants that might be in the water? Can it clean those out?
M: No, it can’t remove salt and chemicals. But those are not really major concerns when we’re out hiking and camping.
W: Mm. . . How long will a straw last?
M: For about 100 gallons, but don’t worry about measuring that large amount of water. There is a built-in safety device.[21]The mineral and chemical filters become clogged long before the limit is reached and the straw stops drawing water.
W: I think I’ll go to get one for my camping trip this weekend.
19. How does the man describe the water purifier?
