I am heading to Egypt for a month and was planning on using my Sweetwater filter plus SweetWater purifier solution, to avoid having many dozens of plastic water bottles going into the landfill. But I just realized I probably can't take the purifier solution on the plane (as checked baggage) per TSA. Has anyone else tried taking the solution on a plane? Katadyn tablets are a possibility, but get expensive after awhile. Maybe a SteriPEN is a better way to go.

Check first, but I think they recently changed the rules on some liquids in the cabin up to 3oz. You also shouldn't have any problems if you store it in your checked luggage since it's not corrosive, pressurized or flammable . Declare it either way for sure.
