Add much-needed moisture to the air in your home with the Equate 1.1 Gallon 250 sq ft Invisible Cool Mist Humidifier. This humidifier features filtered invisible cool mist technology that provides two key benefits: it absorbs water from the water tank to disperse into the air and it helps capture minerals and impurities in the water. The unique design includes an easy-grip handle and large tank opening for easy filling and carrying, and the 1.1-gallon tank provides plenty of water for you to run this humidifier up to 24 hours. Don't forget to purchase replacement filters: Equate Humidifier Filter Replacement, PCWF813 or RWF813. Say goodbye to dry air and hello to your new Equate 1.1 Gallon 250 sq ft Invisible Cool Mist Humidifier. Making the right health decisions can be challenging.
