How is the flow rate compared to Mini and Squeeze?

Much better than mini and I’d say close to squeeze

Will it thread onto a platypus hydration bag for clean water storage/carry?

The platypus products do not always fit our filters well. Our filters and pouches use the standard 28 mm threading.

Is this the same filter that is on the select systems s1, s2, s3?

It looks like it's the same filter. The bottle the primary and the micro the secondary.

How much does just the filter weigh (dry, before any use)?

On my scale it weighs 1.83 oz out of the box.
