Types of water filter: which one fits your home?
Choose Faucet-mounted filters for filtered or unfiltered water from the tap; Under-sink systems for larger quantities of water; Point-of-entry systems for situations where the water source poses consistent and significant contamination challenges. The right choice depends on the quantity of water that requires treatment each day and where treated water is needed.
