The Philips air humidifier can be attributed to solutions of the middle price segment. The model works on the principle of air washing, is characterized by relatively small dimensions (34x25x25 cm) and is notable for the simplest maintenance. It is recommended to use it in relatively small rooms - up to 25 m². The Philips HU4803 humidifier supports proprietary NanoCloud technology, that is, it is equipped with a special humidifying filter that also performs antibacterial treatment, that is, it cleans the air from pathogens. Unlike most competitors, such an element is a consumable, which is recommended to be changed every six months, instead of doing time-consuming cleaning. The model also provides a built-in hygrostat with three automatic modes of operation - maintaining humidity at around...40, 50 or 60%. Performance can be adjusted manually, while the maximum water flow will be 200 ml per hour. The liquid reservoir holds 2 liters, so without refueling the device will work for at least 8 hours (conditionally all night). Among other features, it is worth highlighting the touch control with a display that shows the current humidity, helps to set the night mode or set the timer.

Model overview based on user reviews  
The Philips HU4803 humidifier is praised for its quiet operation, stylish design, and ease of use, featuring functions like night mode, humidity indicator, and automatic shutdown when water is low. However, some users express dissatisfaction with its humidification performance, noting that it does not significantly increase humidity even in small rooms, and the built-in hygrometer may not be accurate. While it slightly cleans the air and allows for aroma oil use, the device's 2-liter water tank and filter design are criticized, with some users feeling it doesn't meet the advertised specifications. Overall, while it has some appealing features, its effectiveness in humidifying larger spaces is questioned.

Alenause Philips HU4803 week i recommend it should buy
A bucket with a fan for 11,000 rubles. Do not buy it, do not repeat my mistakes!
7 December 2015 
Hello, dear ladies and gentlemen! I bought this technical marvel, aka nano cloud, at Media Markt for 11,000 rubles. Basically, it's just a bucket with a fan. (structurally made incorrectly - for some reason, there are holes in the middle of the bucket, couldn't they make them higher to at least have a 5-liter volume ???) The volume is only 2 liters. The filter is a piece of cut paper (costs 600 rubles, if you decide to replace it, you still have to search for it thoroughly in stores). It raises the humidity by 5-10% per day, and that's with completely closed plastic windows and a closed door in a 12.5 sq.m room. That is, it doesn't meet the declared specifications at all. To be of any use to a child, you need to put it right under the child's nose. The built-in hygrometer lies, overstates by 10-20%. Accordingly, if it reaches 60%, it turns off, but in reality, in the corner of the room, other hygrometers show 40%!!! In other words, it doesn't cope with its main function - humidification - at all. It slightly cleans the air, plus you can add aroma oil there, it will be like an inhaler. That's all the pluses. Overall, I didn't think Avent makes such crap...
Beautiful design, quiet at 1st speed. Slightly cleans the air in the room.
DOES NOT MOISTURIZE AT ALL!!!
use Philips HU4803 week i recommend it don't buy
For a small room, yak is not aired, you can take it for a larger holiday.

It will not fully humidify a 12m room; it's a bit weak for maintaining humidity.
Price is normal.
Glitch in auto mode does not raise humidity to the indicated level.
use Philips HU4803 less than month
