Product review (5 stars): Excellent water filter
We live in an area where the water comes out of the faucet tasting like dirt and minerals.  Since we bought our new refrigerator we have been drinking the water after it has been passed through the PUR PBSS filter.  It tastes much cleaner and is noticeably cleaner without floating particles and without cloudiness.

The filter lasts ~4-5 months at our usage which is about 1-2 liters per day and slightly higher on the weekends.

It is extremely easy to install and I bought it on Amazon subscribe and save, with a setting of every 5 months.  The discount is great, and the filter arrives just about the time that the refrigerator starts to request a new filter.
