Diana Young –
Used this on a fishing trip and it worked well. The mesh kept out sand and small debris. Easy to rinse and fits nicely in my boat’s storage space.
Sonia Paterson –
Good for filtering water from lakes. The 18 mesh filter caught small particles, but it’s not a replacement for boiling. Works well in practice.
Richard Pullman –
Perfect for boating. Lightweight and the mesh stays clean after use. I’ve used it on several trips and it holds up well.
