Questions & Answers
Is this whole house iron water filter environmentally friendly?
Yes. The Iron-OX5 doesn’t use chemicals during the filtration process. Instead, it relies on natural interactions between oxygen and iron to help filter your water. That means this iron filter for home use may be more environmentally friendly than other potential solutions.
How does this system filter iron from water?
Instead of relying on chemicals, the Iron-OX5 uses an environmentally friendly process called aeration. The aeration process oxidizes dissolved iron, turning it into filterable particles. The media in the tank acts as a catalyst to enhance the reaction between the oxygen and iron. A second layer of Culligan G-50 media ensures efficient filtration of the iron particles.
How long does this iron water filter system last?
The lifespan of any iron filter for well and city water depends on various factors, including your water usage, iron levels and more. However, this system has a durable design that improves its longevity, including a sturdy fiberglass media tank with a filament-wound exterior and non-permeable inner tank shell designed for years of continual service.
Is the Aquasential Select Plus Series Iron-OX5 Water Filter a good choice for well water?
Yes. The Iron-OX5 is designed to target and address iron content in tap water — a particularly common issue for homes with wells. Iron is a naturally occurring element in soil, rocks, minerals and even the Earth’s crust. That means it can easily find its way into groundwater — the source of many private wells. As a result, well water may frequently cause rust-like stains, reduced appliance lifespan and efficiency, plumbing clogs and other frustrations. The Iron-OX5 addresses all these problems and more.
