Hi, there! As a long-distance hiker, we carried Sawyer Squeeze filters long before I ever found out I had bronchiectasis and MAC. They do require a little hand strength to squeeze the water from the catch bag to through the filter, but they work beautifully.

They do make a filter for attachment to a tap, which would be probably what you would want. We've not personally used it, but I can attest to Sawyer being quality stuff, at least the versions we've used for years on trails.
