AIO HYDROGEN SULFIDE REMOVAL SYSTEMS

We Only sell Wholesale | Same day shipping

Get rid of rotten egg smell for good with AIO hydrogen sulfide removal systems from All For Water. Air Injection Oxidation (AIO) filters are one of the most effective chemical-free ways to remove hydrogen sulfide (H2S), iron, and manganese from well water, making them the go-to sulfur water filter for dealers, installers, and water treatment professionals.

How Air Injection Hydrogen Sulfide Filters Work

An AIO system keeps a pocket of compressed air at the top of the mineral tank. As water passes through this air head, dissolved hydrogen sulfide, iron, and manganese are oxidized into solid particles that are captured by the catalytic filter media below. During backwash, the control valve flushes the trapped contaminants to drain and draws in fresh air to recharge the oxidation zone, so the system regenerates itself automatically with no chlorine, hydrogen peroxide, or potassium permanganate.

Benefits of AIO Sulfur Water Filters

Removes hydrogen sulfide (rotten egg odor), iron, and manganese in a single tank
100% chemical-free treatment, with no feed pumps, solution tanks, or refills
Self-regenerating air pocket refreshed with every backwash cycle
Stops black, orange, and brown staining on fixtures and laundry
Protects water softeners, RO membranes, water heaters, and plumbing from fouling
Low maintenance and low operating cost for residential, commercial, and light industrial wells

Choosing the Right Hydrogen Sulfide Removal System

Sizing an AIO filter depends on your hydrogen sulfide, iron, and manganese levels, along with pH, flow rate, and well pump capacity. For best results, test the raw water before selecting a system. AIO filters work best on low to moderate H2S levels; very high concentrations may call for chemical injection or a combined treatment approach. Our technical team can help you size the correct system for your application.

Frequently Asked Questions

What causes the rotten egg smell in well water?

The smell comes from dissolved hydrogen sulfide gas, usually produced by sulfur-reducing bacteria or natural geology in the aquifer. Even very low concentrations are noticeable.

Does an AIO filter need chemicals?

No. AIO systems use oxygen from air to oxidize contaminants, then regenerate automatically through backwashing.

Should an AIO filter go before a water softener?

Yes. Installing the AIO system ahead of a softener or RO system removes sulfur, iron, and manganese first, protecting downstream resin and membranes.

<h2>16" x 65" AIO Hydrogen Sulfide Filter for Well Water</h2>
<p>Get rid of the rotten egg smell for good. The 16x65 AIO is a complete single-tank <strong>air injection hydrogen sulfide filter</strong> that removes sulfur odor, iron, and manganese from well water with no chlorine, peroxide, or potassium permanganate. Its 16" x 65" tank holds the most filter media in our AIO line, making it a commercial-grade sulfur water filter for businesses, farms, multi-family buildings, estates, and other high-demand applications.</p>
<h2>How the AIO Sulfur Filter Works</h2>
<p>The WS1EE control valve maintains a pocket of air at the top of the tank. As water passes through the air head, dissolved hydrogen sulfide (H2S), iron, and manganese are oxidized into solid particles that are trapped by the media bed. During each automatic backwash, the trapped contaminants are flushed to drain and fresh air is drawn in to recharge the oxidation zone, so the system regenerates itself with no chemicals to add.</p>
<h2>Key Features</h2>

<li>Removes hydrogen sulfide (rotten egg odor)</li>
<li>100% chemical-free air injection oxidation</li>
<li>Self-regenerating air pocket recharged on every backwash cycle</li>
<li>WS1EE control valve with automatic, programmable backwash</li>
<li>Stops black, orange, and brown staining on fixtures, laundry, and equipment</li>

<h2>Is the 16x65 the Right Size?</h2>
<p>The 16" x 65" AIO filter is built for commercial, agricultural, and high-demand residential applications. A tank this size requires a substantial backwash flow, so confirm that your well pump can deliver the backwash flow rate the system requires before installing. Also check that your installation area has enough ceiling clearance for the tall 65" tank and control valve. For very large homes with more moderate demand, consider the 14" x 65" model, or browse our full range of <a href="/aio-hydrogen-sulfide-removal-systems">AIO hydrogen sulfide removal systems</a>.</p>
<h2>Frequently Asked Questions</h2>
<h3>Will this filter remove the rotten egg smell from my well water?</h3>
<p>Yes. The air injection process oxidizes hydrogen sulfide gas, the cause of the rotten egg smell, and the media bed filters it out.</p>
<h3>Does an AIO filter use chemicals or salt?</h3>
<p>No. It uses oxygen from air to oxidize contaminants and regenerates automatically by backwashing.</p>
<h3>Does it need electricity?</h3>
<p>Yes. The control valve plugs into a standard outlet to run its automatic backwash schedule.</p>
<h3>Should it be installed before a water softener?</h3>
<p>Yes. Install the AIO filter ahead of a softener or RO system to protect resin and membranes from sulfur, iron, and manganese.</p>
<h3>Is the 16x65 AIO suitable for commercial use?</h3>
<p>Yes. Its large media bed makes it well suited to businesses, farms, multi-family buildings, and other applications with high water demand.</p>
<h3>What is the difference between the 14x65 and 16x65 AIO?</h3>
<p>Both tanks are 65" tall, but the 16x65 is wider and holds more filter media, giving it the most capacity in our AIO line. The 14x65 suits very large homes and needs less backwash flow from the well pump.</p>
