Viqua PRO20
#2 in Over 12 GPMFull review
The certified pick for a large home or a small business on a private well. It costs a lot, but the dose is measured and certified.

2.7/5
A large home unit with a published Class A dose flow and a 3 year controller warranty, for less than Viqua’s monitored models. Add a sensor if no one tests the water.

Pros
- 16 GPM at the full 40 mJ/cm² dose, enough for a large home
- Colour screen shows lamp life, errors and a QR code to the lamp change video
- Ports for a UV sensor or shutoff valve can be added later
- Rated to 150 psi, more headroom than most
Cons
- No UV sensor as sold; that needs the LB6 version or an add on sensor
- A genuine RL-850 lamp costs about $133 on Amazon every year
- The 36 in chamber needs wall length plus room to pull the lamp
- Not NSF certified

Viqua VH410M
#3 in Over 12 GPMFull review
