It sounds like you're dropping it on the ground. You need to put the purifier in your bar and place it from there.

I just discovered this game yesterday. Liking it a lot so far!
Anyway, here's my raft setup after about 5 hours of play on the save file:
Lots of item nets, lots of chests, lots of water purifiers. The tower on the right has more storage and a walled-off palm tree farming area. I use the hole in the middle of the floor to lure the shark under the raft so I can attack it safely from above. Currently sitting on about 60 cooked shark meat thanks to that hole :P
