hang on... I'm silly... if I'm screwing one of these onto the tap, it would be processing the softened water... I'm not sure if any of these could go straight onto the garden hose, lol. thoughts?

"Filtering" will not remove salts from the water. They may remove off-odors and particulates from water (assuming those were present in the first place) but will do nothing for the water quality from the orchids' point of view.
For very small amounts of water, something like the zero-water filters (which are actually deionizers) will take minerals out of the water. (Britta filters won't do anything) . For the amount of water it produces, really pricey - small RO units aren't all that expensive, beats killing plants. Or you could buy jugs of distilled water... again you will have to do the math to figure out where the "break even" point with an RO unit is.
