The AIO Series Chemical Free Iron Filter is intended to be an effective and economical way to remove iron from water without the use of messy and dangerous chemicals or expensive pumps or an external venturi. The AIO valve uses a unique process to create an air bubble at the upper portion of the tank to oxidize any ferrous iron prior to being filtered by the media. It can also be used to remove low concentrations of dissolved hydrogen sulfide and manganese from water.
How Does the AIO Series Filter Work?
This filter works by adding oxygen to the incoming water by passing it through a bubble of compressed air. The water is then passed through a special filter bed. The special media not only increases the pH of the water to enhance iron removal but also acts as a physical barrier to trap iron precipitate. As more water passes through this iron filter, the oxygen in the unit is used up, and the media gets loaded with iron. The regeneration process then begins in order to replenish the supply of oxygen, and to backwash the precipitated iron trapped in the media bed. The iron removal efficiency will be more effective with high pH water. The filter is fitted with an inlet check valve to prevent any air from flowing backwards out of the filter tank.

FAQs
The AIO (Air Induction Oxidation) Series filters can remove iron, manganese, and hydrogen sulphide from well water.
Note: There are three different types of AIO Series filters: AIO, AIOM, and AIOC. It is critical to know the water characteristics before determining which unit will best deal with your water issues.
Each of the three BIF Series configurations has different capabilities and operating parameters:
AIO:
Maximum Iron: 30 ppm combined (ferrous + ferric)
Maximum Manganese: 0.0 ppm
Maximum Hydrogen Sulphide: Trace
pH: 7.0 – 8.5
AIOM:
Maximum Iron: 30 ppm combined (ferrous + ferric)
Maximum Manganese: 1.0 ppm
Maximum Hydrogen Sulphide: Trace
pH: < 7.0 ppm
AIOC (Catalytic Carbon):
Maximum Iron: 0.0 ppm combined (ferrous + ferric)
Maximum Manganese: 0.0 ppm
Maximum Hydrogen Sulphide: 5.0 ppm
pH: 6.5 – 8.5
The single-tank AIO Series systems work by adding oxygen to the incoming water by passing it through a bubble of compressed air. The water is then passed through a special filter bed to remove the contaminant(s).
The special media not only increases the pH of the water to enhance iron removal, but also acts as a physical barrier to trap iron precipitate.
No chemicals are used in the entire process making it clean, environmentally-friendly, and low maintenance. No mess!
Yes! The best way to know which AIO Series water filtration you need is to perform a test to know the characteristics of your water. We test it onsite as things like pH and iron parameters can change when exposed to oxygen. Our tests will provide better numbers for those factors than a lab test.

Yes. Like a water softener, the media bed has a certain capacity for removing contaminants. Once that threshold is reached, the media bed needs to be cleaned out of these contaminants so it can go through the cycle again.
Unlike a water softener, the AIO Series will also replenish its supply of oxygen during the regeneration process. Because of the nature of the contaminants being removed, a regeneration will usually occur every three to four days depending upon water usage and the level of contaminants.
Hydrotech, the manufacturer of the AIO Series, has four different valve configurations. As a company, Pristine Water Solutions has elected to exclusively use its top-rated valve—the 89 Series valve.
The 89 Series is Hydrotech’s highest efficiency control valve. Its 80-character touch pad LCD display is simple to use. It has 1″ valve porting and high capacity. It is extremely efficient with its water usage during regeneration (and for salt usage for softeners).
It carries an NSF/ANSI 44 CSA B483.1 certification and a 7-year warranty.
