Here's a video on How to fix up aerator / diverter of P3200 counter-top water filter to mouth of faucet.
The countertops P3200C (Chrome) or P3200W (White) are simple to install and usually requires NO other accessories except for maybe a light hook to hold up the 1/4" tubing if you do not want it off the counter. There are so many types from the DIY shops. This is what I got from Home-Fix. Do request for a piece from us if you require it, then you do not have to buy the whole pack.
