This BONECO Humidifier Air Washer W300 is a filterless dual-purpose device that works both as a humidifier and a purifier, elegant, easy to use, and safe for kids.

Here you have a system that operates with a disc that is kept wet as long as there is water in its huge 12 liters tank. So this is one of the largest devices of this type and it can operate up to 3 days with one tank. It is formally in the group of cold mist humidifiers.

The mentioned disc rotates through the water that is on the bottom, and at the same time air is sucked in the system. In the case of particles or pollution of any kind in the air, they will be attracted to the wet disc surface and then washed out as it rotates through the water. So they and deposited inside while the clean vapor will leave the device. You have the air washed and humidified at the same time.

In other words, here the water acts as an effective natural filter, so there is no filter replacement ever. This is a self-regulating evaporation design which ensures that the right amount of air humidity is always in the room.

A device of this type can be used in all seasons and in such a system air automatically collects moisture, so you will not have it too much. This is a great option for allergy sufferers, a system with a natural air cleaning principle. This is the same what you have in yet another device presented here in the site, the Venta LW25 Airwasher 2-in-1 Humidifier and Air Purifier.

Other features include two performance levels for the day or night, and the device is also equipped with a LED that lets you know when water needs to be refilled. As for the cleaning, this is easy, you can wash the parts in a dishwasher or washing machine.

This device is essential oils compatible so you have a fragrance container for such a purpose.

You might want to know that Boneco is a Swiss Company and it has been around for more than half a century already. They claim that they use high-quality materials that provide years of service.
