3. Install a new filter cartridge. Position the filter head with the arrow facing the unlocked position, then insert the cartridge. Turn the new cartridge to lock it, and finally turn on the water faucet to see if there is a leak.

What are the common undersink water filter types and how do they work?

Conventional under sink filter
The feed water is sourced from the undersink cold water pipe. It passes through a flexible plastic tube and gets to the water filter. After filtration, it is transported from the filter to the dedicated filter faucet through another flexible plastic tube. The user gets the filtered water from this dedicated faucet right on the top of the sink. The filtration process starts when the user opens the tap, hence the system requires constant pressure to send the water from the cold water pipe to the filter and finally out of the faucet.
Simple under sink water filter
The source water leaves the cold water supply to the filter for filtration and finally dispensed through the regular water sink faucet. The hot water does not undergo filtration. The more common version is one without a distinct ledge as the flexible undersink pipes are easier to use. Unlike the hard copper undersink pipes, the flexible pipes facilitate a simple and cost-effective DIY installation.
Most under counter water filters can deliver excellent filtration performance because they adopt activated carbon filtration, present as advanced carbon block filters. For the Waterdrop replacement filter cartridge for under counter water filter, the filtration is handled by the premium carbon materials sourced from the Sri Lanka coconut shell. This ensures users the filter can always operate under a superior reduction performance.
