The Pure Enrichment HUME Max Humidifier is a 1 gallon top fill ultrasonic cool mist humidifier for rooms up to 475 sq ft, with up to 38 hours of runtime on low and a 5 year warranty. For more models, see our Humidifiers page.
Our Verdict
The HUME Max does the basics very well: easy top fill, long runtime on low, simple touch controls and an unusually long warranty for the price.
It has no humidity sensor or app, so you set the mist level yourself. If you want auto mode, look at the HUME Sense.

Design
The 1 gallon tank fills from the top or lifts off for the sink, and the unit comes apart into three pieces for cleaning.
The compact body fits on a desk, side table or nightstand, and a few drops of essential oil can scent the room.
Controls
Three mist levels give up to 38 hours on low, 23 on medium or 15 on high.
Touch controls include three timer settings and an optional night light.
Placement Tips
Set the humidifier on a flat, water-safe surface at least a couple of feet off the floor if you can, and aim the mist into open air rather than at walls, wood furniture, curtains or electronics. Keep it a few feet from the bed or crib so moisture spreads through the room before it reaches you.
Check the room with a hygrometer for the first few days. Most homes feel best between 40 and 60 percent relative humidity, and if windows start to fog or the room smells musty, turn the output down or let the auto mode hold a lower target.
Running Costs and Care
Running costs are low: a humidifier uses far less electricity than a space heater or air conditioner, and the main extras are water, any filters or wicks, and cleaning supplies. Warm mist models use more power than cool mist or evaporative units because they heat the water.
Empty and dry the tank when you can, and clean it at least once a week so bacteria and mold do not build up. Distilled or filtered water reduces white dust from ultrasonic units and slows scale in every type. Before storing it for summer, clean and dry every part.
How It Compares
Against the Levoit Classic 160, the HUME Max holds more water and covers more space, while the Levoit is smaller and cheaper.
Against the Pure Enrichment HUME Sense, the Max lacks a sensor but costs less.
