The technology
Engineered for the cleanest water possible
Three pillars that make Jasonne Kneefel the most advanced home filtration system on the market.
Smart App Monitoring
Track water quality, flow rate, and filter life in real time. Get push notifications before a cartridge needs replacing — never guess again.
Eco-Friendly by Design
Replaceable cartridges made from recycled materials, plus a closed-loop return program. One system replaces ~3,000 single-use bottles a year.

key stages
How it works
Four stages from tap to perfection
Every drop passes through a precision-engineered sequence that strips away the bad and restores the good.
1 · Pre-Filter
Larger particles, rust, and sediment down to 5 microns are captured first to protect the downstream stages.
2 · Activated Carbon
Compressed coconut-shell carbon strips out chlorine, VOCs, and taste/odor compounds.
3 · Reverse Osmosis
A 0.0001-micron membrane removes lead, arsenic, fluoride, PFAS, and dissolved solids.
4 · Remineralization
Healthy calcium and magnesium are added back for crisp, balanced, great-tasting water.
Built for California water
Local water has local problems. We solve them.
From the hard groundwater of the Inland Empire to chloraminated LA aqueduct water, California's supply brings unique challenges. Jasonne Kneefel is engineered and tested against the contaminants actually found in Golden State tap water.
CovinaLos Angeles CountyOrange CountyInland Empire
Proudly serving Southern California from our home base at 780 W Glentana St, Covina \u2014 meeting California SB-1148 and CalEPA drinking water standards.
PFAS & “forever chemicals”
California communities from Covina to the Central Valley have detected PFAS in municipal supplies. Our RO membrane is certified to reduce these persistent chemicals below detection.
Hard water & mineral scale
Southern California groundwater is notoriously hard — averaging 180–300 ppm of calcium carbonate. Our remineralization stage balances hardness instead of leaving chalky scale on fixtures.
Lead & aging service lines
Older homes across the LA basin may still have lead service lines or brass fittings. Our filtration removes lead down to 0.0001 microns, well beyond CA SB-1148 limits.
Drought & recycled water
As California expands recycled and desalinated water, trace contaminants and chloramine byproducts rise. Multi-stage carbon + RO keeps every glass clean regardless of source.

FAQ
Questions, answered
Most cartridges last 6–12 months depending on usage and water quality. Our app tracks real usage and sends a notification when a replacement is due.
No — most customers self-install in under 30 minutes with the included hardware and step-by-step guide. Professional installation is available in select areas.
Our 7-stage system is certified to reduce lead, chlorine, PFAS, microplastics, fluoride, arsenic, VOCs, and bacteria down to 0.0001 microns.
The remineralization stage adds calcium and magnesium back after filtration, so your water stays balanced and great-tasting.
Every system comes with a 60-day risk-free trial. If you're not satisfied, return it for a full refund — no questions asked.
