Product review (5 stars): Does the job it was supposed to
How to review a water filter? Well, first of all, let's consider what is expected from a filter:
1- Performance: It seems to do a good job. We don't feel the taste of tap water (chlorine) using this filter.
2- Ease of use/installation: If you know how to replace a light bulb, you know how to install this filter.
3- Durability: Except for one bad unit that Amazon kindly refunded me, all filters I got so far lasted 6 to 8 months with regular use, what is within my expectations.
4- Price: A little bit high, but considering its durability and performance, the cost x benefit is positive.

I did not test any non-OEM brands to compare to this one. I am happy with it, so no reason to risk just to save a few bucks.
