This is the first line of defense in the system. Made of polypropylene (PP), the sediment filter traps large physical particles like rust, sand, dirt, silt, and other visible debris. By removing these larger contaminants, it not only improves the water clarity but also protects the more delicate filters that follow, extending their lifespan and ensuring they can work at peak performance.

Water often contains chemicals such as chlorine, pesticides, herbicides, and volatile organic compounds (VOCs) that affect both taste and safety. The pre-carbon filter (often a high-density carbon block) adsorbs these impurities. Think of this stage as a shield against chemical pollutants—it neutralizes chlorine that would otherwise damage the RO membrane, while also eliminating bad tastes and odors that make tap water unpleasant.

This is the heart of the system. The RO membrane uses microscopic pores (as small as 0.0001 microns) to remove up to 99% of over 1,000 contaminants. This includes heavy metals (lead, mercury, arsenic), fluoride, nitrates, pharmaceuticals, and even microplastics. Because it works at such a fine molecular level, the RO membrane ensures that the water is stripped of nearly all harmful pollutants, delivering a level of purification you can’t achieve with standard filters alone.
