I need to disperse some CS into the air right away for a coughing dog. Is Walgreen's personal ultrasonic humidifier still the one of choice? In reading through my files on it, it's still unclear as to whether the filter should be left on or off.
We bought a humidifier from Wal-Mart (not Walgreen's) and removed the flat-sheet filter that covers the pan, but nothing's happening. Without the filter, the liquid level doesn't decrease, so I'm thinking that the "filter" is necessary to whisk the liquid up so the fan can disperse the drops into the air. We have to get this straightened out by THIS afternoon, so I appreciate your quick input. Thanks. Nenah
