Rain Filter Plate for Downspout Pre-Filtration: First-Line Defense for Clean Rainwater

A high-quality rain filter plate at the downspout entry is the most cost-effective upgrade for any rainwater system—blocking debris and protecting tanks, pipes, and pumps from clogs or damage.

Project Case — Vancouver Green Roof Community

In 2023, a new residential green roof project in Vancouver installed pre-filtration rain filter plates on every downspout.
Results included:

• 96% reduction in gutter blockages and tank sediment
• Easy seasonal removal/cleaning (less than 2 minutes each)
• Rainwater certified to CSA B128.3 Canadian Rainwater Standard
• SGS Water Quality Testing passed

“Our gutter and tank cleaning costs dropped dramatically after using downspout pre-filter plates.” — Community Manager, Vancouver

Why Use Downspout Pre-Filtration Plates?

Stops Debris at the Source

Captures leaves, seed pods, sand, insects, and large grit before they enter pipes or tanks—prevents expensive overflows and blockages.

Durable, Eco-Friendly, Easy to Install

Plates are made from stainless, composite, or UV-stable polymer—screw-on, snap-in, or drop-in design for all downspout sizes.

Maintains Water Quality

Pre-filtered water is much cleaner—less sediment, fewer bad smells, easier downstream filtration.
