Common questions
Toppen systems do not create wastewater. High flow, no pressure loss, pharmaceutical-grade filtration down to 20 nm — including PFAS, pathogens, parasites and microplastics.
Choose WW or MW when you order. If you have a water test, our engineers can tune the system. Residential units run 5–10, 10–20, or 20–40 GPM (Gallons per Minute).
Most applications: one change per year. Filter kits stay with the matching Toppen system. Sign up for a reminder at 10–11 months on the contact page.
Toppen products cover your water main entry and under-sink units. We suggest under sink because pipes inside have lead solder and can have contaminants from past use. This creates a double barrier, entry and point-of-use (POU). Vollara products are mainly CleanAir products, except the pH dialer — LivingWater Machine. Choose what pH CleanWater you want at your tap.
