Review on 🚰 Enhance Water Purity with 5 Stage Reverse Osmosis Filter Replacement Set (RFK-DRO5, Formerly ROFK5) by Kristy Esposo

These correspond to the properties of my original filters, but are significantly cheaper than buying them from the original company. It must be ensured that the connection for the last stage (activated carbon filter) is correct. This last stage filter is a 1/4" quick connect (insert 1/4" hose). To remove the hose, insert the fitting and pull out the hose. This and most others have a small retractable locking ring that keeps the fitting from being pushed in. You can see the fitting type in the picture.
