Best filter out there IMO. Not badly priced, as well. Every 6 months or so I replace and find myself astonished at the weight of the old filter! Seems to trap debris within the filter, never getting to my hair or skin.
I’m sure the filter is great, but I ordered the handheld shower head with a free extra filter and they gave me the filter that goes with their other stationary shower head. I cannot use the filter they gave me, hence the 1 star.
