Collection: Filters & Diverters

Clean water begins at the point of capture. The efficiency and longevity of any water reuse system depend entirely on the quality of primary filtration. Our collection of rainwater filters and diverters provides high-tech solutions to intercept and purify runoff before it enters your Rainwater Harvesting system, protecting your pumps and irrigation nozzles from sediment and organic debris.

From downspout diverters for residential rain barrels to high-capacity in-line filters for commercial underground tanks, these components are engineered to withstand extreme UV exposure and the harsh freeze-thaw cycles of the Canada.

Advanced Filtration Technologies

Self-Cleaning Cascade Filters: Utilizing stainless steel mesh to separate organic matter (leaves, needles, moss) from the flow. These rainwater harvesting filters direct clean water to the tank while flushing debris to the storm drain.
First-Flush Diverter Systems: Automated technology that isolates the initial, most contaminated runoff—washing away roof dust and pollutants before they reach your clean water storage.
Winter Bypass Engineering: Specialized downspout diverters equipped with a seasonal switch. One click redirects water away from the tank during winter to prevent ice expansion damage.
High-Flow Capacity: Engineered to maintain up to 95% hydraulic efficiency, ensuring maximum water capture even during intense North American storm events.

The Role of Primary Filtration in System Longevity

Primary treatment is a biological insurance policy for your Complete Rainwater System. By preventing organic matter from entering the "quiet zone" of your reservoir, you eliminate the source of bacterial growth and anaerobic odors.

Self-Cleaning Mechanisms

Modern cyclonic and cascade filters use water velocity to scrub the filter screen. This reduces maintenance and protects your submerged pumps from abrasive particles that can wear down impellers or clog drip irrigation emitters.

First-Flush Diversion: The Cleanest Capture

A First-Flush Diverter is essential for properties with asphalt or bitumen roofs. It captures the initial "wash-off," allowing only the purified secondary flow into your tank. This significantly extends the lifespan of your secondary fine filtration units and maintains water quality in your stormwater management system.

Pro-Perspective: Maintenance in High-Debris Zones

If your property is surrounded by heavy foliage (pines or deciduous trees), we recommend a dual-stage approach. Combine a leaf-beater downspout screen with an in-line filter. This prevents large debris from reaching the fine mesh, reducing your cleaning frequency to once or twice per year.

Frequently Asked Questions About Rainwater Filters & Diverters

Can I integrate filters with my existing pond auto-fill system?

Yes. Integrating primary rainwater filtration ensures that the water used for your pond auto-fill is free of organic debris and roof pollutants. This protects your pond's biological balance and prevents fine sediment from clogging delicate mechanical valves and auto-fill sensors.

What is the best filter for a residential rain barrel?

For residential applications, a self-cleaning downspout diverter is the most efficient choice. These units are designed to remove large debris while automatically managing overflow prevention; once the barrel is full, the diverter redirects excess water back into the downspout to protect your foundation.

How often should I clean my rainwater filter?

We recommend a full cleaning twice a year—during spring startup and fall shutdown. However, if your catchment area is under heavy tree cover (high pine needle or leaf fall), a quarterly visual inspection is advised to maintain maximum flow rates and filtration efficiency.
