I had seen the air wick scented oil air freshener but had not tried it. I finally gave it a chance and I'm so glad I did. I purchased the adapter separately and installed the Air Wick scented oil in lavender and chamomile which come in a pack of 5. My house smelled amazing and it wasn't strong. I bought a different brand which made my head hurt because of how strong the smell was. I will definitely be purchasing again once the 5 pack is over.
