Color: Black Product Dimensions: 75L x 47W x 25H Material: Polyvinyl Chloride (PVC) Shape: Oval Effective Heating and Insulation: The heater pump with a 1350W capacity delivers strong heating power, warming the water from 68℉ to 104℉ (raising the water temperature by 1.8-3.6℉ per hour). Once the desired temperature is reached, the thermostatic system manages energy optimally. The included spa cover helps retain heat, or you can also place a sponge pad on the bottom (not included). Bubble Jets Massage: The inflatable hot tub features 100 air jets that generate thousands of bubbles, providing a gentle massage experience for 1-2 people to comfortably enjoy relaxation and soothing warm hydrotherapy. Superior Filtration System: Equipped with an advanced filtration system, the blow-up hot tub keeps the water clean. Two easily replaceable filter cartridges efficiently capture sand, debris, and hair. After 168 hours of use, the heat pump will prompt you to replace the filter for optimal filtration performance. When the filter loses its filtering function, the control panel will automatically alarm and display FC. Durable PVC Material: The blow-up hot tub boasts super waterproofing and high resilience. PVC material provides resistance to piercing and tearing, against abrasions from sharp rocks, and is tightly linked to the pump to prevent leaks. Warm Tips: The portable hot tub can be easily deflated and folded within minutes, making it easy to store.
