The reason I did not give you five stars is because when I ordered a seven stage replacement set, you sent me six items. I know you people are better than that just based on the quality of your product.
The filter arrived quickly. I purchased to replace once I need to. Haven’t tried the new ones but I expect them to work as well as the ones I previously purchased.
This project is great!
