Rainy Filters

What Rainy Filters does

Rainy Filters (legally Farmland Rainwater Harvesting System) is a Bengaluru-headquartered, privately held Indian manufacturer founded in 2002 that designs, produces, distributes, and installs rainwater harvesting filters and groundwater recharge systems. The company sells a tiered line of five rooftop filter models — FL-80, FL-150, FL-250, FL-350, and FL-500 — engineered for rooftops ranging from 110 to 500 sq.m, and markets a patented V-Wire Injection Well technology for artificial groundwater recharge on plots of 1 to 8 acres.

The underlying technology is mechanical and physics-based rather than digital. The Dual Intensity filter design operates on cohesive force at low rainfall intensity and centrifugal force at high intensity, delivering 90%+ filtration efficiency without manual adjustment, while a self-cleaning auto-flush mechanism eliminates maintenance. The V-Wire Injection Well uses V-Wire screens with a non-clogging slot structure to percolate 25,000–50,000 litres per 24 hours per well. All products run on gravitational force with no external energy requirement. Manufacturing, R&D, and a hydraulic testing lab are co-located on a 5-acre owned campus at Hadihalli, Chikmagalur.

Rainy makes money primarily through one-time hardware sales of filter units and one-time/multi-year project contracts for turnkey V-Wire installation. Distribution is multi-channel: a 131-dealer network across India, an own e-commerce storefront (shop.rainyfilters.com), Amazon Marketplace listings, and direct enterprise sales for large projects. Customer segments include residential homeowners, industrial and commercial facilities (UltraTech Cement, Bharat Electronics, Life Line Feeds, IFFCO, Roach Life Spaces), government and rural water supply programmes (Karnataka Government, Suvarna Jala, JALA SHAKTHI ABHIYAN), and educational institutions. Exports cover 14 countries. The company has no disclosed external funding and operates as a bootstrapped, founder-led SME.
