Solutions for every home.

Flagship offers one premium whole home water filtration solution for all—in six sizes to suit every home.


All models are made to last 10 years and meet or exceed NSF61 standards for potable water. Filtration media is eco-friendly and should be replaced every 10 years. Old media is safe to reuse for landscape composting.


Tank, bottom distributor plate, conditioning chamber, riser, tube, controller head include a 10-year warranty.

Filter Ability

Remove chlorine, volatile organic compounds, herbicides, pesticides, pharmaceuticals, chloramine up to 2ppm and many more hazardous contaminates.
Backwash Cycle: 8-min backwash plus a 4-min rinse, once a week. The amount of water each model uses varies. Backwashed water is clean and free of salt, making it safe for use in landscaping, refilling a swimming pool, or even plumbed into the sewer line.

Carbon Filter Media

Ultra pure catalytic granular coconut shell based activated carbon.

KDF55 Filter Media

High purity copper-zinc formula removes heavy metals like lead and mercury and extends the life of carbon.
