The price was actually $629.59 but with a disount of $59.95, I was able to obtain it for $570.00 using a discount code 421896-disc.
It may be a little pricey but the fact that I don't have to change filters every six month like others makes it unique. I have a peace of mind because the filter was certified by NSF which is an independent organization that tests and approve filters. I did not want to buy a water filter because it's cheaper. I bought a filter that will give me a peace of mind. Also, when I consider how often I have to change filter cartridge, this one is better. It's only once a year.
The filter can remove a wide varieties of contaminants in my water. No more brown or smelly water. Plus, I save money when I don't have to buy bottled water. My family and I have bought bottled water for a long time.
