Protect every drop in your home from forever chemicals.
The REN Water Ultimate PFAS Filtration System is a whole-house, point-of-entry solution engineered to reduce PFAS/PFOS (“forever chemicals”), sediment, chlorine, taste, and odor so the water at every faucet, shower, and appliance is cleaner and healthier.
Why it matters
PFAS don’t break down easily and can accumulate over time. This system is specially designed to lower these synthetic compounds in your water, helping bring levels in line with (or better than) the EPA’s recommended guidance. The result is greater peace of mind for drinking, cooking, bathing, and everyday use.
Key protections
- Sediment defense – Captures dirt, sand, rust, and particles down to 5 microns so downstream filters stay effective longer.
- Salt-free scale conditioning – Reduces limescale buildup without salt, protecting pipes, fixtures, water heaters, and appliances from hard-water damage.
- Dual 1-micron PFAS filtration – Two specialized stages target PFAS/PFOS while also improving taste, odor, and clarity and reducing chlorine and other common contaminants.
- High-flow performance – Maintains strong water pressure for homes with up to 6 bathrooms or peak demand around 15 gallons per minute with no noticeable drop in flow.
- Truly low maintenance - No wastewater, no drainage required, and no heavy 40 lb resin bags to haul or dispose of.
- Made in the USA - Built for reliability with straightforward DIY installation.
Enjoy cleaner, better-tasting water throughout your entire home with advanced filtration that is simple to install and built to last.
