A Swiss Company that exists since 1956 with more than half a century of heritage. Boneco Air Washer W300 is one exceptional humidifier build with high-quality components. The entire structure is made with a non-corrosive titanium membrane that guarantees zero leakage. Air vents are nicely secluded from the front with only a simple black dial knob. Instead, you will find it at the side and top of the humidifier. Moving to the back, you have a very large 3.2 gallon transparent water tank that allows days of operation without stopping. There’s even a fragrance container to support the use of essential oils. Overall, the 16.2 x 15.7 x 11 in and 14.1 lb in weight is by no means small, the top-notch fitting of the product will justify its bulkiness.

BONECO W300 Control Panel

Operating BONECO is dead easy with a front simple dial knob. Turn the knob clockwise to switch on the machine, turn it counterclockwise to switch it off. If you see the red LED light lit up, that means the water tank is empty. Either refill it at the kitchen by grabbing on the top handle or just fill it directly without the need to remove the water tank.

Filters And Performance

No fancy UV or ionizer technology here. Through self-regulating evaporation, BONECO Air Washer W300 will humidify and clean your air all at one go. First, the evaporator mat rotates through the water thereby moisturizing the air. As more air is coming in, the filled water will act as a barrier to filters out all the impurities from the air. This includes mineral deposits like dust, mold, smog, pollen, and bacteria. The dry air will then take in the moisture and disperse out as invincible mist. Continuously doing so with help relieve dry skin itchiness, prevent static shock, and provide healthy air for all family members.

^ Replacement filters/ estimated cost
To have a product associated with Swiss, it is not going to be cheap. BONECO W300 Air Washer is a 300 priced product that may seem expensive to many, it is a tag cheaper than some of the models in this category. For the price you paid, basic air purifier functionality is bundled in as well. What can be the deal-breaker though is the costly evaporator mat that requires replacing every quarterly. Unless you are staying in a rather clean environment or you don't mind the filter upkeeping, W300 can be a burden for you.
There are plenty of places you could buy BONECO Air Washer W300 except the official website (not available). Comparing a few different sites, Amazon has the best deal by a stretch with free prime shipping. You can also skip the account registration as by this stage everyone will have an Amazon account. In case you are still pondering, there are the standard no questions asked return policy if you are not happy with the purchase.
