💧 KENT Grand IoT. RO+UV+UF+Alkaline+Copper+TDS. UV In-Tank. Smart IoT Filter Alerts. 8L. 20 LPH. Delhi NCR.
The KENT Grand IoT is the premium smart water purifier at Mahajan Electronics — 7-stage purification combining RO (dissolved impurities, heavy metals, pesticides), UV (bacteria and viruses), UF (physical particles), TDS Control (essential mineral retention), Copper enrichment (immunity and metabolism support), Alkaline enhancement (pH balance), and UV In-Tank LED (prevents bacterial regrowth in stored water — the feature standard purifiers lack); IoT smart monitoring with real-time filter health, automatic service alerts, and maintenance history on smartphone; Auto Flush RO membrane; Digital Purity Display; 20 LPH flow rate; 8L storage; fully automatic operation; and KENT's 4-year free service network. Compatible with all Delhi NCR water sources — borewell, tanker, municipal, and brackish.
💧 Seven purification stages — each addressing a different water quality dimension
UV In-Tank — the feature standard RO purifiers skip and why it matters for stored water safety
Standard RO+UV purifiers apply UV treatment to water as it flows through the purification column — bacteria and viruses are deactivated during the purification process, and purified water enters the storage tank clean. The problem is what happens after storage: the 8-litre tank that holds purified water between uses is a warm, moist enclosed space — ideal conditions for bacterial regrowth from residual organic matter, biofilm development on tank surfaces, and contamination from tank condensation. Standard purifiers have no mechanism to prevent this regrowth; purified water that has sat in the tank for several hours, particularly overnight, may contain bacteria that weren't present when it was first purified. UV In-Tank addresses this with a UV LED unit mounted inside the storage tank that continuously irradiates the stored water — any bacteria that enter the tank post-purification, or that survive in the tank environment, are continuously deactivated throughout the storage period. For Delhi NCR households where the purifier fills overnight and the first glass of water each morning has been in the tank for 6–8 hours, UV In-Tank ensures that the water dispensed is as clean as water purified seconds ago — not degraded by overnight tank storage conditions.
IoT Smart Monitoring — replacing the "when did I last change the filter?" problem
The most common RO purifier maintenance failure in Indian households is delayed filter replacement — filters are consumables that degrade gradually, producing water that appears clean but has reduced purification efficacy as the membrane and filters age. Without active monitoring, most households replace filters reactively (when flow rate drops noticeably or when the annual service technician visits) rather than proactively at the optimal replacement point. KENT Grand IoT's connected monitoring tracks filter health in real time — the IoT system measures actual filter performance metrics rather than estimating based on calendar time, sends automatic service request alerts directly to KENT's service network when filter replacement is due, notifies the household's smartphone of maintenance requirements before performance degrades, and maintains a complete maintenance history record. For busy households where water purifier maintenance competes with other priorities, IoT monitoring converts a reactive maintenance process (remember to call the service centre) into a proactive automated one (the purifier tells you when action is needed and requests the service visit automatically).
Copper + Alkaline — the health enrichment layer beyond standard RO purification
Standard RO purification removes dissolved impurities but strips the water of both harmful dissolved solids and beneficial minerals. KENT Grand IoT's TDS Control retains the essential minerals (calcium, magnesium, potassium) that RO would otherwise remove. The Copper enrichment stage then adds trace copper ions to the purified water — copper vessels have been used in Indian households for water storage for centuries, with Ayurvedic tradition and modern research both supporting copper-infused water's antimicrobial properties and potential benefits for digestion, immunity, and metabolism. The Alkaline enhancement stage adjusts water pH above neutral (7.0) to approximately 7.5–8.5, reducing the mild acidity that standard RO water can have after mineral stripping. For families making the switch from mineral water bottles — which are typically alkaline and mineral-rich — the KENT Grand IoT produces water with a taste and mineral profile closer to premium bottled water than standard RO purified water, removing one of the common objections to home purifiers from households accustomed to bottled water quality.
TDS Control — why retaining minerals matters for Delhi NCR's municipal water
Delhi NCR's municipal water supply has TDS levels typically ranging from 200–500 ppm — within the acceptable drinking range but with mineral content that standard RO removes entirely. Pure RO water at near-zero TDS tastes flat and slightly acidic; the beneficial minerals (calcium for bone health, magnesium for muscle function, potassium for cardiovascular health) are collateral losses in the purification process. KENT's TDS Control system allows a calibrated proportion of source water to bypass the RO membrane and blend with RO-purified water, restoring the essential mineral content while maintaining the removal of harmful dissolved impurities. The result is purified water that retains approximately 150–200 ppm TDS from beneficial minerals — the range that WHO guidelines identify as optimal for drinking water mineral content — rather than the near-zero TDS that standard RO produces.
Auto Flush RO Membrane
Automatically flushes the RO membrane at regular intervals — preventing the concentration polarisation and scaling that accumulates on membranes in hard water areas (Delhi NCR's 300–600 ppm TDS supply). Scale buildup on RO membranes is the primary cause of membrane performance degradation and premature replacement need; Auto Flush extends membrane life and maintains consistent flow rate and purification efficacy between manual service visits.
Digital Purity Display
Real-time display of water purity status, filter life percentage, RO flow rate, and water quality indicators — visible at a glance without opening the app. The display provides immediate feedback on whether the current water quality meets the purifier's standards and whether any filter element is approaching replacement — the first indication that action is needed before the IoT notification arrives.
All Delhi NCR Water Sources
Compatible with borewell (high TDS, high hardness — common in outer Delhi and Noida), municipal tap (medium TDS, treated but chlorinated — most of central Delhi), tanker water (variable TDS, microbiologically uncertain — common in areas with supply interruptions), and brackish water (high dissolved salts). The 7-stage combination handles the full spectrum of water quality conditions across Delhi NCR's varied supply sources without requiring source-specific configuration.
Fully Automatic Operation
Auto ON/OFF based on tank level — the purifier activates when the storage tank drops below a threshold level and shuts off when full, without manual intervention. For households where water consumption varies (larger loads on weekends, entertaining, cooking-intensive days), automatic operation ensures the tank is always adequately filled without the overflow waste or pump burn-out risk of manual operation.
