Does the job well.

It arrived very quickly. It increased the flow of water compared to my last filter, and the water tastes great. I have a water softener for high iron content in my water but the Aquacrest really makes a difference, I am glad its flowing much better too.

The filter can last up to 6 months or 500 gallons. But the filter life will vary based on your water conditions. Therefore, it is recommended you change your filter every 6 months or 500 gallons when you notice a change in taste, odor, or flow of the water being filtered for optimal performance.
Yes. It is highly recommended you flush the filter before using. Water filters are made from advanced coconut activated carbon, so there are some carbon fines in the filter. You need to flush firstly to remove those carbon fines to get clean water.
Yes, please rest assured that you can use it.
