We have had this unit for several weeks now and are please ar how quiet it is on the sleep mode. My husband cleaned the unit for the first time and said it was pretty easy to do. He liked being able to get to all the parts and clean them before there's any buildup of "crud" like we had to deal with in our old humidifier. We decided to order another filter so that we could do a trade off with each cleaning, especially as we know in the winter time it will probably take longer than 24 hours for the washed filter to dry and we don't want to be without our humidifier.

I purchased 1 Evaporative Humidifier "HOI" 5 months ago ,and 1 air purifier ,the largest and most expensive .Yes you pay for quality and in this case the power .i am ecstatic on the effectiveness of both products. My only problem is that i wish the humidifier was larger. The air purifiers is important, if you are familiar with the biology of Parasites .Bacteria ,and Virus ,not to mention the chemical trails that we see behind airplanes and unknown aerosols

I purchased the Airdog MOI in March of 2024 to use in the bedroom which becomes very dry at night. This humidifier is perfect as it has a mode that will turn off the lights of the water level and dim the display. In addition, the unit itself is very quiet. My husband suffers from all sorts of allergies and we had both been suffering from how dry our bedroom was over the winter. This device works beautifully! It holds a lot of water and provides the moisture we need for a healthier nights rest. We have our Airdog MOI placed near our window with heavy blackout curtains and the curtains and surrounding area never get wet as our previous humidifier would do. During the day we leave the unit on Smart Mode to help maintain the moisture level. Not only does the Airdog MOI work extremely well, it is also easy to fill and easy to clean.

It will beep at night and wake you up when on "night mode", and you also can't use any of the other higher fanspeeds on night mode. This makes it not work well for a bedroom and seems poorly designed for the price. This is a shame because all other aspects of the unit seem pretty decent.

After the recent Los Angeles fires the air in the air was very bad, I quickly got one of these air dogs and best decisions ever omg thanks for your product we’ll definitely give 5 starts
