Twenty-five dollars more than the aeration Oxi-Gen and a materially more capable machine, which makes the choice between them a question of water chemistry rather than budget. Peroxide oxidises faster and more completely than injected air, so it handles higher iron and, importantly, dissolved sulfide that aeration only partly addresses. Proportional injection is the detail that matters: dosing to actual flow avoids both the underdosing that lets odour through at high demand and the overdosing that wastes chemical at low flow. The ceramic rotary disc valve is a sensible choice for water carrying precipitate. Against that, peroxide is a consumable you will keep buying and the injection pump is a wear item. If a water test shows iron comfortably under 8 ppm and the sulfide is largely particulate, the Oxi-Gen costs less to run and is the better buy.
US Water Systems does not publish enough of this system’s specifications for it to be scored against our eight criteria.
- Peroxide handles higher iron and dissolved sulfide than aeration
- Proportional injection doses to actual flow
- Ceramic rotary disc valve suits precipitate-carrying water
- Only marginally more expensive than the aeration model
- Two tank sizes
- Peroxide is a permanent running cost
- Injection pump is a wear item needing periodic service
- More maintenance than aeration for water that does not need it
- Requires drain line and power
- No system certification stated
- Leak complaints on tank-type units appear in the brand's Trustpilot pool
Hydrogen peroxide injection with a proportional pump that matches dose to flow, followed by an oxidising filter bed. Handles higher iron loads and dissolved hydrogen sulfide that aeration leaves behind. Ceramic rotary disc valve for durability on well water.
