Condition: Like NEW, my dogs never drank from it…I did install the 1 filter it came with and had the bowl connected/running for a few days. The bowl is fully sanitized and cleaned✔️ Size: 7L- Large bowl (designed for medium to large dogs) **Continuous flowing water to encourage pet hydration. Durable stainless steel construction which blocks 99.9% of bacteria! Easy to refill and clean. Quiet pump operation for calm use. When filter needs to be replaced (filter lasts about a month or so), you can purchase them on the Selene website or on Amazon✔️ 🔶Accepting any “Reasonable Offers”🔶
