Sana Vida PureFlow Ionic Pleat Filter
Electrokinetic Nanofiber Shell + Carbon Block Core | PFAS + Microplastics + Microorganisms | Turret or Citadel

The most advanced filter in the Sana Vida line, built for water affected by industry and agriculture, especially where PFAS (“forever chemicals”), microplastics, or microorganisms are a concern.

Most microplastics, PFAS, and microorganisms carry a negative charge. The PureFlow’s pleated nanofiber shell is positively charged, so it attracts and holds them instead of letting them pass. Behind the shell, a dense carbon block core reduces chlorine, fluoride, lead, and more. PFAS, PFOA and PFOS, microplastics, chlorine, chloramine, lead, and pharmaceuticals come down by more than 99%. Heavy metals, VOCs, trihalomethanes, glyphosate, and pesticides and herbicides are reduced by more than 98%. Fluoride, including all common types added to tap water, is reduced by more than 95%, and radionuclides by more than 94%. The filter also reduces mercury, asbestos, and MTBE. It is tested to NSF/ANSI Standards 42, 53, and 401 and meets NSF Protocol P231 for microbiological water purifiers, and there is no activated alumina in the core.

It comes in two sizes. The Turret (2" x 7") filters up to 600 gallons for chlorine and chloramine and up to 500 gallons for PFAS, and fits up to 4 per Sana Vida system. The Citadel (2.6" x 7") filters up to 1,250 gallons for chlorine and chloramine and up to 750 gallons for PFAS, and fits up to 2 per system. Both fit every Sana Vida copper water filtration system and most other 7" gravity filter systems. They are made in the USA for Sertodo.

Before first use, run two full chambers of water through the new filter and give it to your plants. This clears any unwanted taste before you start drinking. Replace each filter at its rated capacity or once a year. Unlike a ceramic shell, the nanofiber shell can’t be scrubbed clean, so if your water carries a lot of sediment, the GuardFlow filter pairs a similar carbon block core with a ceramic shell you can scrub.

Why we love it:

• The charged nanofiber shell captures PFAS, microplastics, and microorganisms by attraction, which a mechanical shell can’t do
• PFAS, PFOA and PFOS, and microplastics reduced by more than 99%, the figures that matter most for industrial and agricultural water
• Meets the NSF P231 protocol for microbiological water purifiers, on top of NSF/ANSI 42, 53, and 401 testing
• Carbon block core with no activated alumina
• Two sizes, with the Citadel rated for up to 1,250 gallons for chlorine and chloramine
• Fits every Sana Vida copper system, and most other 7" gravity filters
• 10% off when bought with a Sana Vida system

Native Manor Note: Some contaminants don’t filter out by size alone. PFAS and microplastics carry a charge, and the PureFlow uses that charge to hold them. It’s the filter to reach for when the water has farms or industry upstream.
