Water filter for hot water?

can I use a regular water filter to filter the hot water in my kitchen sink? For some reason I am getting settlement in my hot water to the kitchen which causes the faucet to clog..It does not bother in the bath and washer machine...I want to put a filter of some type in the line..It is not like the hot water will be running through it all the time..Only when doing a few dishs or what ever...I am getting tired of tearing the thing apart all the time..Myself,it seems like a regular filter will work but the Home Depot man said the PVC will not hold up..Please help me here...Thanks......Oh and the water is filtered before the water heater....
