I purchased this in late March of this year for my dog's toilet, so it's still under warranty. I'm putting it up for sale because I'm going to place a large air purifier in the living room and consolidate the air purification there. I didn't mount it on the wall, so the wall-mounting kit is unused. The accessories are also almost all unused and complete. I think it's in very clean condition, with no noticeable scratches or stains. I've disposed of the box, but I plan to wrap it in bubble wrap and put it in a cardboard box, and I will take care to pack it carefully. This is a set of the SUNSTAR QAIS-air- 04 dedicated stand + 04 main unit, "For those who can't wall-mount" QAIS-air- 04A1J-OW OP-W. It's a pet odor eliminator/deodorizer, disinfectant, and photocatalyst air purifier. It doesn't require filter replacement, is quiet, and can be wall-mounted. It's designed for pet toilet odors, urine odors, and provides peace of mind, safety, and comfort. SUNSTAR.
