LG HydroTower Max: a humidifier-purifier for big rooms
LG's new PuriCare HydroTower Max boils water before humidifying, purifies up to 66 m² and adjusts output with AI. How it compares with the original HydroTower.

Quick verdictThe Max is the one for open-plan living rooms: more mist, four times the purifying area and AI control. The original HydroTower still suits a bedroom.

LG Electronics launched the PuriCare HydroTower Max in South Korea on 18 October, as Yonhap reports. It is a bigger sibling of LG's HydroTower humidifier, built for living rooms rather than bedrooms, and it combines humidification and air purification in one tower. LG lists it at 2,390,000 won. The company has not announced plans for other markets.
How it works
The headline feature is hygiene. LG filters the water, heats it to 100°C to sterilise it, then turns it into fine mist with ultrasonic vibration. Air going out passes through the purifier filter first, and after a session the unit pulls back leftover water and dries itself. LG calls this a four-step process: filtration, sterilisation, purification and drying.
New for the Max is what LG calls "space-customised AI humidification": sensors assess the room's size and temperature and set the output automatically, so you don't have to keep adjusting it. Other details from LG's announcement and product page:
- up to 850 cc of mist per hour and a 4.5-litre stainless steel tank, good for up to 18 hours in normal mode at medium fan speed;
- air purification for about 66 m², with a PM1.0 dust sensor; both functions can run together or separately;
- a 26 dB sleep mode, a light sensor that switches the lamps off, three themed mood lights (campfire, aurora, ripples) plus 12 colours;
- hidden wheels and Wi-Fi control through LG's ThinQ app.
HydroTower Max vs HydroTower
| HydroTower Max | HydroTower | |
|---|---|---|
| Product type | Humidifier + air purifier | Humidifier with purifying mode |
| Max humidification | 850 cc/h | 700 cc/h |
| Purifying area | 66 m² | 16.6 m² |
| AI humidification | Yes, room-aware | No, target humidity only |
| Weight / wheels | 21.2 kg, built-in wheels | 18.7 kg, wheels sold separately |
+ Pros
- Boiled, filtered water is a real hygiene advantage over basic ultrasonic units
- Covers a large living room in one device
− Cons
- Expensive, and only announced for South Korea so far
- Heavy at over 21 kg, and the 4.5-litre tank still needs a daily refill
Our verdict
HydroTower Max for big rooms
If you want one device to handle winter dryness and year-round dust in an open-plan space, the Max is the more complete package. For a bedroom, LG itself points buyers to the original HydroTower, or the humidify-only HydroEssential.
