    Great purifier/humidifier combo

    Excellent purifier/humidifier. Dyson got humidification right by using an evaporator ring instead of mist or ultrasonic which leaves the air sticky. By using evaporation the air holds the moisture naturally and doesn’t leave the air feeling thick. 40% to 60% humidity is perfect for healthy breathing and keeps skin from being dry, this machine accomplishes that perfectly. When humidification isn’t needed that portion either won’t be used or you can turn it off leaving the fan/purification side running and this machine moves more air than the other purifiers.

    I bought this during spring and usually my allergies are the worst during springtime. I decided to make this purchase and after the first day, it purified my room right away. I sleep better, allergies are gone, and breathe better as well. Again, it is pricey, but you pay what you get for.

    Over all a GREAT investment. I wasn’t expecting a fan that actually worked well but to my surprise this one worked wonders. We really needed a purifier because we have pets in the home and my husband gets bad allergies. This not only notifies me when our air quality is low but it lets me customize my settings to help with the process. I do feel that for the price it also came with a heater but I don’t purchase the 3in 1 so I can’t be too upset about that.
