AIRCARE Console MA1201 vs Companion CM330 vs AURORA AUV20
AIRCARE’s Console MA1201, Companion CM330 and AURORA AUV20 are not just three cabinet sizes. The Console and Companion use evaporative wicks; the AURORA makes ultrasonic cool mist. Their water handling and humidity controls differ enough that the room-area claims alone should not decide the choice.
Start with the operating method, not the largest number
The MA1201 is the largest of these examples: AIRCARE lists 3.6 gallons and coverage up to 3,600 square feet. The Companion CM330 models hold 1.6 gallons and are listed up to 1,000 square feet. The AURORA AUV20AWHT holds one gallon and is listed up to 750 square feet. These are manufacturer-stated upper figures, not guarantees for a particular house or a measured claim that rooms will reach the same humidity. Use them to understand relative intended scale, then consider the room layout, doors, refill handling and the control style you actually want.
MA1201 and CM330 move air through a replaceable wick. AUV20 uses an ultrasonic disk and a removable tank with a cap on the underside. That distinction changes routine care: a wick model requires inspection and eventual replacement, whereas the AUV20 does not use a wick but requires its tank, base and oscillator cleaning. The AUV20 manual permits essential oil only on its separate pad; the MA1201 manual prohibits oils, and the CM330 guide also offers no oil route. Do not transfer one model’s add-on instructions to another.
The Console’s capacity is not a quick-pour tank
The MA1201 manual describes a removable water bottle that feeds the base. Fill it at a faucet, let it drain into the base, then repeat the fill to reach the full 3.6 gallons. It is a larger reserve than the other two choices, but the refill steps and handling are still part of the purchase decision. The cabinet measures 20.5 by 21.5 by 14.5 inches and rides on casters. Make sure you can leave room around the floor unit and move it safely where you need it.
By contrast, the CM330’s 1.6-gallon base is filled through its sloped front grille. The AUV20’s smaller one-gallon reservoir lifts off, but the manual directs you to unscrew the bottom cap and invert the tank. So neither the Console’s bottle refill nor the AUV20’s bottom-cap fill is equivalent to a straight top-fill jug or an open pour-in reservoir. If avoiding a particular refill posture matters, the comparison question should be about that posture—not just capacity.
Match controls to the humidity routine
The MA1201 manual documents digital humidity settings from 25% to 65%, a humidistat that turns the fan off at the selected target and an Auto setting that adjusts fan speed. It also says the 65% setting runs continuously. The current page lists four fan speeds and the manual labels the displayed range F1 through F4; high settings are louder, with the guide comparing them to a box fan. That combination offers more target control than the AUV20’s output dial, which has no documented humidity cutoff.
The CM330 controls are smaller-family variants: CM330A uses a variable analog humidity setting, while CM330D uses three humidity presets. Both are evaporative and include their series wick. The MA1201 is the choice among these when the larger reserve, digital target setting and Auto fan behavior outweigh its cabinet size and wick care. The CM330 is a more compact way to get evaporative humidification. Choose the AUV20 if you prefer a smaller ultrasonic model with manual output and a separate oil pad; do not choose it expecting automatic humidity control.
Read the manuals as an ownership plan
For the Console, AIRCARE recommends a level position with two inches of wall clearance around the cord humidistat, and cautions against placing it under a window. The manual describes a central location near a cold-air return for circulation and says a multi-story home should use the bottom floor. Cleaning involves emptying and unplugging, separate bottle and base care, rinsing and full drying. It prohibits essential oils and water softeners. The wick is not a set-and-forget component: its CF code after 720 hours asks you to check the MAF1, not blindly replace it.
For the AUV20, the separate manual details tank, cap, tray, cartridge and oscillator cleaning, including the pad-only oil route. The CM330 manual describes its own small-base refill, humidistat and SGL1040 replacement wick. Each product’s source supports a different answer to “How much maintenance and what kind of refill work can I accept?” Read the long reviews for the Console MA1201, Companion analog, Companion digital and AURORA AUV20 before treating capacity as the main difference.
Evidence: AIRCARE’s current product pages and the exact MA1201, CM330-series and AUV20AWHT owner instructions. Coverage, runtime and capacities are manufacturer statements; room outcomes depend on conditions. Each feature and accessory description is limited to its exact model or family variant.
