You need a whole-house filter to provide filtered water to your home's faucets. Why? Because the treatment and disinfectant compounds in your water can become airborne when heated in your shower, bath, dishwasher, or laundry.
On average, whole-house water filters will function for Three to Six Months of Pre-Filtering. Carbon Filter: 12 Months. Post-Filter: One Year or Less
The longer water is exposed to a specific water filtration medium, the more contaminants it extracts. This would necessitate a whole-house system to slow down the flow. Your shower, appliances, kitchen basins, and all other faucets would lose water pressure.
The majority of the finest water purifiers in India require filter replacement every 6-8 months. However, the frequency of filter replacement is also determined by the water's quality and consumption. These filters remove various types of contaminants from water at distinct stages.
