3Gal/12L/405oz Large Capacity: The 3-gallon/ 12L dog water fountain is ideal for large dogs, cats, and multi-pet households, reducing the need for frequent refills. The water level window allows you to check the water level at a glance, so you don't need to lift the lid as often | No Splashing Deeper Tray: The water tray of this pet water fountain is 1.2 inches deeper, which is more in line with the dog's drinking method. The tilted design of the water tray allows the dog to drink easier without splashing, no matter how big the dog or pet is. The floor is cleaner | Swirling Water Flow & Embedded Water Tray: The low-water outlet and the tilted tray design create two circles of swirlings, which wash away impurities such as hair in the tray, and the flowing water also attracts the attention of pets. The embedded tray is also less likely to be knocked over by your dog | Ultra Silent Design & Multi-Layers Filtration: This pet water fountain operates quietly, with a noise level ＜25 dB, making it barely noticeable in daily life. The fountain features a 4-layer filtration system that includes activated carbon, ion exchange resin, non-woven fabric, and a high-density pump sponge. This combination ensures fresh, clean water. We recommend replacing the filter every 2 weeks for the pet's health | 304 Stainless Steel Material: Crafted from 304 stainless steel, the water tank and tray are safer and more durable than plastic. This material ensures clean, healthy pet water and helps prevent feline acne. Plus, it's suitable for dishwashers below 60 ℃/140 ℉
