Better than venerable Squeeze because
"Better than venerable Squeeze because 1. Closing end caps means they don’t dry out between seasons; no need for any special saline or pre-soak next season 2. Integrity check lets you know when you failed to protect from freezing and need to replace (end caps also mean it won’t dribble into your insulation overnight). 2. 5 backflushing requires no equipment besides a standard thread bottle, and it’s less prone to clogging anyway because pore size is larger, not chasing claims of virus removal irrelevant in most places."
