This is a set of two dark gray AirLove 3 Lollipop units. I purchased them from the official website about two years ago and used them only during the summer. They have been stored at home since then. There are some visible stains on the waterproof parts (please check the photos). Since I didn't let my child eat snacks in the stroller (when using the seat), I think they are in relatively clean condition. I will also include two replacement filters (unopened). The fans have been tested and are working. The boxes are not included. - Brand: poled - Model Name: airluv - Filter Type: HEPA filter - Quantity: 2 sets - Color: Dark Gray & White Thank you for looking.
