A water filtration system removes impurities such as sediment, chlorine, heavy metals, bacteria, and other contaminants from water. It works by passing water through one or more filters, each designed to target specific pollutants, resulting in cleaner and safer drinking water.

Depending on the system, water filtration can remove chlorine, lead, mercury, pesticides, sediments, bacteria, viruses, and dissolved solids. Advanced systems like RO (Reverse Osmosis) and UV filtration provide higher levels of purification.

Filter replacement frequency depends on the system type, water quality, and usage. Typically, sediment and carbon filters are replaced every 3–6 months, while RO membranes last 2–3 years. Regular maintenance ensures optimal performance.

Choosing the right system depends on your water source, contamination level, usage requirements, and budget. A water quality test can help determine the most suitable filtration solution, whether it’s a whole-house system, under-sink filter, or RO unit.
