Why Fiber Technology?
Our filtration technology delivers stronger performance, better pressure, and longer life than traditional filters. Here’s why:
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.
.avif)
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.
.avif)
Full Flow
The highly permeable fiber membrane allows water to pass through quickly, delivering consistent flow and uninterrupted pressure throughout your home.
.avif)
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.
Which P1+ System is Right For You?
Find your household size for the perfect system. We recommend choosing based on the number of people living in your household for the most accurate filter lifespan.

"Great systems happy to be working with Purely as an installation partner."
"I'm a huge stickler when it comes to the quality of the water I drink. Keanu from Purely was a breeze to deal with and extremely helpful. The device itself was very easy to install and the result speaks for itself. I can honestly say that my tap water has become my favorite hydration source. And the before/after difference is incredible. Definitely recommend!"

"I purchased two shower heads and an under the sink filter and I absolutely love both products. Firstly, the shower head has helped my hair become so much more healthy and shinny, I no longer feel that residue from regular tap water. Secondly, the under the sink filter was so easy to install and I haven’t had to replace my cartridge in over a year! I would highly recommend."
