You can tell the difference in air quality with this device
I’ve had this for over a year and can attest it excels at removing cooking odors from the kitchen. Recently I burnt food under the broiler which set  off our smoke detectors and left an awful lingering burnt odor. After leaving the germ guardian plugged in for 3 hours the smell dissipated from the lower level of our house. The nifty thing is this unit is small and portable allowing you to move it to whatever space it is needed in. In my home Even though I use it everyday I do not need to keep it continuously on so I have yet to swap out the light. Once you get used to having this around you can definitely tell the difference if you in air quality if you forget to plug it in while cooking.
