AprilAire 80 Replacement Canister for Steam Humidifier - Reliable

In this review the AprilAire 80 replacement canister is evaluated as the direct service part for AprilAire steam humidifier models 800, 801, 865, and 866. The bottom line: this genuine canister is for homeowners who want a straightforward, factory-designed replacement to restore steam output quickly and reliably. Its primary benefit is a perfect fit and proven electrode design that produces steam for whole-home humidification, so anyone using an AprilAire Model 800 or 865 looking to maintain proper humidity should consider it.

Key Features

• Genuine AprilAire construction: The canister is made in the USA to match original equipment tolerances so it installs and fits like the factory part.
• Annual replacement recommendation: Replacing the canister every year helps the humidifier keep producing the expected steam output and maintain consistent humidity control.
• Electrode steam generation: Current runs between electrodes inside the canister to boil water and create steam, supporting up to about 34.6 gallons of moisture per day under continuous use.
• 0.75 gallon tank capacity: The internal tank and electrode design allow roughly 1 to 3 gallons of moisture per hour depending on operating conditions, giving enough output for whole-home systems.
• Includes O-ring for seal: The supplied O-ring helps ensure a leak-proof connection when the canister is installed in the humidifier housing.
• Healthy Air App compatible: The canister works with the Healthy Air App for replacement reminders and humidity guidance, simplifying maintenance.

Who It's For

This canister is aimed at owners of AprilAire steam humidifiers model 800, 801, 865, or 866 who need a direct OEM replacement. It is especially useful for households that prefer factory parts to preserve system performance and compatibility with the AprilAire Healthy Air App for maintenance reminders.

Customers who should look elsewhere include owners of non-AprilAire steam units or anyone seeking an aftermarket redesign; the canister relies on electrode technology and is intended as a like-for-like service part rather than an upgrade or filtration solution.
