This is the smallest air purifier we own. But, trust me this works fantastic in the kitchen, laundry room or the bathrooms!! We have an air purifier in every single room of our home. These will make such a difference in the air quality in each room. With this one you can even add a few drops of essential oil and youll enjoy a calming scent in your home. If you think these arent doing anything...just go out for a short period of time and reenter your home. Youll be amazed!!
