At 2 oz and 20$, are there any negatives to this filter? Seems like a good way to go.
Just conjecture, but with a smaller surface area on the filter I'd think they would have to be more susceptible to clogging than a larger filter with the same throughput. Not a big deal witha backwashable filter other than carrying the syringe for backwashing. And at that price and weight, you could bring an extra!
I'll definitely be trying one out.
