The P1+ Advantage

Compact & Installer-Friendly

Smart surface-area utilization allows the P1+ to deliver high-performance filtration in a more compact system, requiring less space, less complexity, and a cleaner installation.

Proprietary FO Technology

Our proprietary FO Technology is designed to deliver consistently better-balanced water while improving filtration efficiency and reducing material waste compared to traditional filtration media.

Consistency

Fibre helps reduce channeling by creating a more consistent filtration structure, allowing water to make better contact with the media instead of passing through uneven gaps.

Pressure & Flow

Tested through 1,000+ Canadian home installations and laboratory testing, the P1+ is designed to maintain strong water pressure and flow throughout your home.

Strength & Performance

Engineered for durability, the P1+ has been burst-pressure tested up to 20 bar, nearly 5x the pressure of an average Canadian home.

Performance & Taste Guarantee

We’re so confident you’ll notice a difference in your water that if your system does not perform as intended, you can return it within 30 days of purchase.

Purely Benefits

Financing with Affirm

Flexible payment options that make cleaner water easier to access.

Cost Savings

Reduce bottled water spending and lower long-term replacement costs.

Pregnant Women & Children

Cleaner water for the people in your home who need it most.

Better Water Changes Everything

Skincare

Your skincare starts with the water you rinse with. Residue and dryness can disrupt the skin’s surface, making creams, serums, and moisturizers less effective. Better-balanced water helps create a cleaner foundation for your products to perform.

Showers

Your shower water touches your skin, scalp, and hair every day. Water that leaves residue or disrupts the skin barrier can contribute to dryness, irritation, and rougher-feeling hair.

Ice

Ice is concentrated water. Better-balanced water helps create cleaner-tasting ice, improving the flavour of everything it touches, from water and juices to cocktails and smoothies.

Laundry

Hard water and residual chlorine can dull colour and stiffen fabrics over time. Better-balanced water helps preserve the feel and longevity of your clothes, towels, and bedding load after load.

Drinking & Hydration

Your tap is the most direct way water enters your body. Better-balanced water makes your everyday glass taste cleaner and feel lighter, turning consistent hydration into something you actually look forward to.

Coffee & Tea

Water controls the extraction of flavour. Better-balanced water helps improve taste, aroma, and mineral balance, giving coffee and tea a cleaner, smoother, more refined finish.

Cooking

From boiling pasta to washing produce, water is the foundation of almost every recipe. Better-balanced water can help preserve natural flavour and texture in everything you cook.
