Indoor air and moist enough to maintain mikroatmosfery use moisturizing devices. However, the devices must regulate microclimate without noise while working. Only quiet humidifier operates around the clock, without compromising the comfort of residents.
Some models humidify and purify the air from the microparticles. Humidifiers for the principle of action can be of three types:
- ultrasonic,
- steam,
- traditional.
All kinds improve the air in the room, and each has its own advantages and disadvantages.
Principle of operation
Type of device depends on the method mikroatmosfery moisture saturation.
Steam
Steam apparatus raise humidity in the building turning water into steam. Consist of:
- water tanks,
- dispenser,
- the evaporation chamber,
- heating element
- humidistat.
In addition, manufacturers of complementary features in its sole discretion. For example, the tray set for the aromatic oil.
Water from the container through the dispenser is fed into the evaporation chamber. The heating element in the chamber brings the fluid to a temperature at which it begins to evaporate. Humidistat controls humidity levels and disables the device to reach the set value.
Benefits:
- koefitsient high efficiency;
- low price.
Disadvantages:
- surface gets very hot, so do not place them in the nursery or in the vicinity of the furniture;
- steam humidifier low noise, but louder other species;
- heating facilities in the warm season brings discomfort.
Traditional
It works on the principle of natural air enrichment cold water evaporation. When using this type moisture level depends on the temperature in the room.
Traditional moisturizer comprises:
- fan,
- water tank,
- pallet,
- cartridges.
Water from the tank, passing through the tray impregnates cartridges. Fan passes through them the air flow. There is a natural evaporation of the cold liquid.
Benefits:
- saturated with indoor air by natural means;
- They operate almost silently;
- a high level of security.
Minus - liquid must be distilled or purified, or cartridges are quickly clogged with salt deposits.
Ultrasonic
Ultrasonic humidifier noiseless, unlike other species. The water turns into steam by means of ultrasonic oscillations of the plate. Consists of:
- fan,
- membrane,
- liquid container.
Liquid from the reservoir is supplied in small portions to the membrane, which creates vibrations with ultrasonic frequency. The oscillations are converted into cold water vapor. The fan distributes the resulting vapor through the room.
Benefits:
- quiet operation;
- small size;
- a variety of designs.
Minus - impurities from water to settle on the surface of the objects in the room and form a white coating.
How to choose a quiet instrument
Before buying a humidifier weigh all the pros and cons, check out reviews. Key selection criteria:
The volume of the liquid container. The larger the tank, the longer operation without refueling.
Noise level. Quiet Humidifier can be used around the clock and he does not interfere with sleep.
degree of safety. The device operates on 220V, so it is best to check the quality certificates.
Automating the process. Selecting the best stop on the automatic control, it will lower your participation in the process.
The best representatives
Below is an overview of three of the most silent models.
Boneco U201A
Ultrasonic humidifier with the reservoir volume of 3.6 liters. It is targeted at the premises of 47 m2. For a power control knob. The maximum noise level of 25 dB.
Pros:
- small size;
- It can be used during sleep.
Minus - fugitive base.
Polaris PUH 5206Di
The large-volume liquid 6 liters at a rate of 350 ml per hour. The humidity level can be programmed.
Plus - Built-in ionizer fills the air with oxygen ions.
Minus - it is necessary to clean the mineral filter.
Royal Clima Sanremo
The most inexpensive ultrasound models. The maximum power consumption of 25 watts per hour.
Pros:
- acceptable price;
- small size;
- lower energy costs.
Minus - small tank 3 l often have to refuel.
Each type of humidifier is helpful, but not ideal. All emit a slight noise during operation, but the quietest models ultrasound.
