Any system or method that filters particles and impurities from your water is referred to as a water filtration system. Water filtration is defined as the process of removing any amount of sediment, particles, bacteria, and the chlorine taste from water. It's a filtration system if it has any kind of filter.

Water filters have a reputation for removing pollutants from water. Water softeners are designed to remove minerals from the water that produce hardness and scale, as their name suggests.

Reverse osmosis works by passing water through a semi-permeable membrane with very small pores. Natural minerals, salts, and other organic substances with molecular components bigger than water cannot pass through these pores. As a result, reverse osmosis (RO) is a proven method for eliminating a wide range of pollutants from water.

Lead, asbestos, dissolved organics, radium, and other hazardous heavy metals are examples of such contaminants. Heavyweight volatile organic compounds and chlorinated pesticides are also removed by reverse osmosis.
