Pearl’s CTO Inline Carbon Block Filter acts as a proactive purification stage in domestic RO and UV systems. Crafted from high-grade coconut shell and coal carbon granules, it effectively neutralizes chlorine, organic contaminants, color, and odor while also filtering fine suspended particles. With a micron rating of approximately 5 µm, this filter enhances the overall system’s performance by extending the lifespan of the membrane and reducing maintenance needs. Each filter lasts around 4–8 months (≈ 2500 gallon capacity) and costs about ₹180–₹215, offering excellent value with a 10‑day replacement policy and one-year warranty
