If I wanted to use this to clean dishes...
If I wanted to use this to clean dishes or take a shower and I was all paranoid about dirty water (if you've ever been to egypt you'd understand) could i easily hook up my water filter to this? Its a katadyn Hiker.
No, there is no way to attach a filter. Best you could do would be to put the outflow hose into the shower and pump directly from your water source. The top of the pocket shower is just an opening like a stuff sack or dry sack.
