“I plugged in all six units I purchased around my house where most needed, especially a dusty bedroom corner (see photo). I haven't had them long enough to tell how well they're working, but will monitor the various locations over time. I have a short-haired dog so there's alot of dog hair as well as dust.”
“Just, finally , received my 3. Have noticed
a change, especially in my bedroom. Less stuffy nose and cough. Will be ordering another for the kitchen.”
