My new pure enrichment air filter was a gift from my sister. She has one in her home and she wanted me to experience the good results that she gets from your product. The day she gave me this gift. I was cooking onions and peppers. we turned on the air filter almost immediately with hopes that it would clear the air. By the time we had our dinner, dishes washed and put away, the filter was working and providing cleaner, fresher air than I ever would have thought. I did leave the air freshener on that evening and my morning my air was clean. No smelly residue left in my kitchen and home. So thank you very much. I know I will be using this often.
