CLEAR CARECleaning Disinfection Solution Twin Value Pack Multicolor

Where can I buy the replacement filter in the bottom of the case? Or do I have to buy new with every bottle?

Anyone getting residue left on contacts after cleaning?

does anyone know where to get the lense case only without the solution?????

If I leave my lenses in the solution longer, will it make my lenses more moisturized? I opened a pack yesterday, one is perfect, the other is very dry
