## Description

Rainy FL - 500 Self-Cleaning + Dual Intensity Rainwater Harvesting Filter Suitable for Area Upto 5400 Square Feet, Black,Installation Kit : desertcart.in: Home & Kitchen

Review: totally worth it once set up properly. - Performs Exactly as Promised I’ve been using the Rainy filter for over two years, and it’s been working great. The key is proper installation — if the outlet slope or pipe angle isn’t right, leaves can get stuck, but once adjusted correctly, the system runs smoothly with no clogs. The 250-micron mesh is actually ideal for Indian rooftops — it prevents choking and still filters out dust, leaves, and debris. For finer filtration, I’ve added a small tank filter, and my water stays very clean.
Review: Save water for future gens - Value for money, good quality plastic body.. no electricity needed,, have to clean ss filter after each rain

### ⭐⭐⭐⭐⭐ Best Rainwater Harvesting Filter in India
*by V***N on 25 October 2025*

I’ve seen a few people mention that Rainy only removes large debris — but that’s not been my experience. It easily filters out leaves, dust, and insects, and the water that reaches my tank looks clean and clear. It’s true that very fine particles or algae can pass through — but that’s common for all first-stage filters, even expensive imported ones. The easy fix is to add a simple sand or tank filter after Rainy, which gives crystal-clear water. That’s what I’ve done, and the water quality has been excellent since. What I really appreciate is how low-maintenance the Rainy system is. The stainless steel filter doesn’t rust, cleaning takes just a minute, and parts are easily available. For the price and long-term reliability, it’s been totally worth it for me.
