Why Fiber Technology?

Our structured fiber technology is designed for consistent filtration, strong flow, and a longer-lasting filter—so performance stays steady over time.

Add to cart

Beyond Granules

Traditional filters rely on loose granules that shift over time. As water finds the path of least resistance, filtration can become less even—and the media wears out quickly.

Smarter Structure

A dense, fibrous media creates high surface area and more contact time with the water—guiding flow evenly through the filter for smoother, more consistent performance.

Compact Footprint

More available surface area makes high-performance filtration possible in a smaller format. The P1+ is built to fit cleanly and easily into homes, condos, and apartments.

Longevity

Fiber technology is built to remain evenly structured over time and resist channeling—the result: up to 2 years of use when properly sized to your home’s water needs.

Full Flow

The highly permeable fiber membrane allows water to pass through quickly, delivering consistent flow and uninterrupted pressure throughout your home.

Frequently Asked Questions

Everything you need, answered—so choosing cleaner water feels effortless.

Do you offer installation?

We work with a trusted network of plumbing partners across Canada and can help coordinate installation for you. Our partners are familiar with our systems and can ensure the installation is completed smoothly and correctly.

‍

Where available, we handle the coordination process and help connect you with the right installer for your area.

‍

Can I get my own plumber to do the installation?

Absolutely! Any licensed plumber can install the system with ease. It is a straightforward installation that can typically be completed in around one hour, we provide detailed installation guides and manuals to make the process seamless from start to finish.

How are replacements done, and do they require a plumber?

Replacement is designed to be simple and homeowner-friendly. In most cases, cartridge replacements are DIY and can be completed in under five minutes.

‍

A plumber is not required for standard replacement, and we also provide a detailed step-by-step guide to make the process as easy as possible.

‍

How do I know which Defender system is right for my family?

As a general guideline, we typically recommend:

‍

1–2 people: 1-Stage

3–4 people: 2-Stage

5+ people: 4-Stage

‍

This gives us a strong starting point, which we can then tailor based on your home and usage patterns.

‍

How do you determine the replacement cadence?

By using an industry standard formula of 250L per day, per person, multiplied by the number of people in the home. From there, we compare that estimated household usage to the capacity of the system and recommend a system designed to fall within an approximate two-year replacement cadence. If your home or water usage calls for a different timeline, we tailor the recommendation accordingly.

When will I know it’s time to replace my filters?

We will notify you when it is time to replace them. Your replacement cadence is tailored based on your home size, the number of people in the home, and your overall water usage habits, so the timing is aligned with your household’s actual needs.
