Been using these awhile

The flow is very free, but they do clog in time, so they must be working. Water tastes great, price half of aquasana.

Works well, good filter.

Less expensive, just as good...

So far, so good. Much less expensive than the AQUASANA Mfg. I normally buy for my water filter

Comparable to Aquasana

Works great and fits my aquasana counter top system
