Anden Replacement Steam Canister with O-Ring

Replacement Steam Canister and O-Ring for Anden AS35FP Humidifiers

The Anden AS80 Steam Canister is the replacement canister for Anden Model AS35FP electrode steam humidifiers. The canister is the component in which steam is generated: electrical current runs between two electrodes submerged in water, heating it to a boil and releasing steam that is distributed through the humidifier's fan pack.

As the humidifier operates, dissolved minerals remain in the canister after water evaporates into steam. These minerals accumulate on the electrode surfaces and in the water, increasing conductivity and reducing the effective electrode area over time. Replacing the canister at the start of each heating season restores full steam output and efficiency. Made in Madison, Wisconsin. For use with water conductivity above 300 µS/cm — not compatible with RO water or softened water.

Key Features & Benefits

• Genuine Anden Replacement Part — Factory-produced replacement canister designed specifically for the Anden AS35FP humidifier.
• Restores Steam Output — Fresh electrodes restore full steam generation after mineral depletion reduces output.
• Includes O-Ring — Kit includes the replacement canister and a new O-ring for a complete seal.
• Made in Madison, WI, USA — Manufactured at Anden's facility in Madison, Wisconsin.
• Seasonal Replacement Recommended — Replace at the start of each heating season for peak humidifier performance.
• Conductivity Specification — Designed for water with conductivity above 300 µS/cm. Use the AS80LC canister for conductivity under 300 µS/cm.

Who Should Use This Canister

The Anden AS80 is the correct replacement canister for any Anden AS35FP steam humidifier installation using water with conductivity above 300 µS/cm. If your water conductivity is below 300 µS/cm, or if the unit is running at 120VAC, use the Anden AS80LC (DH4480LC) instead. Do not use RO water or softened water with the AS80 canister.

How Electrode Depletion Reduces Steam Output

Electrode steam humidifiers generate steam by passing electrical current through water between two electrodes. As minerals in the water deposit onto the electrode surfaces over time, those areas become electrically insulated and no longer contribute to current flow or steam generation. The effective electrode area shrinks, and steam output decreases. Eventually the canister must be replaced to restore the original electrode surface. Regular seasonal replacement — rather than waiting until output is noticeably reduced — maintains consistent humidification performance throughout the season.

Frequently Asked Questions

What humidifier does the AS80 fit?

The Anden AS80 is designed for the Anden Model AS35FP steam humidifier.

What water conductivity is the AS80 for?

The AS80 is for water conductivity above 300 µS/cm. For water under 300 µS/cm or 120VAC installations, use the AS80LC (DH4480LC).

Can I use RO water or softened water with this canister?

No. Do not use RO water or softened water with the Anden AS80 canister.

How often should the canister be replaced?

Anden recommends replacing the steam canister at the start of each heating season for consistent performance.

What is included in the kit?

The kit includes the AS80 steam canister and one replacement O-ring.
