The under-sink and whole house water filter device by Pentair can be installed either under your kitchen counter or in the main water supply of your home. It includes a faucet, which is placed on the top of the counter and is connected to the device. You turn the distributor and only filtered water runs. The connection fittings it has are 1/4''. The pipe diameter of the device must be the same as that of your home's water supply for proper installation.
