The main issue against saltwater hot tubs is that salt causes corrosion. At levels of 2,000-3,000 ppm, there should be no worry about damage to finishes and pool equipment. There is one material in particular that doesn’t like salt, that being Buna rubber, which some pump shaft seals are made of. Again, at normal levels, there should be no concern. But if your pump seal begins to leak, we do have pump shaft seal made for high salt or ozone conditions.
Water Filtration System Another important element that we have based our top on is the presence of a quality water filtration system. The reason why it is important is more than obvious as this is the system which ensures the water you sit in will be free of impurities and contaminants.

Of the 3 main inflatable hot tub brands, this hot tub is the largest and has the most bubble jets (140). With an 85-inch diameter and 290 gallon capacity, this Intex model provides more personal relaxation space than any other. More room means it is easier to stretch out and easier to sink down so that bubbling water is lapping around your shoulders. That said we think 4 people is the comfortable max.
Saltwater hot tubs are still using chlorine, but it’s not your father’s chlorine! It’s pure chlorine, or hypochlorous acid, and it can’t be compared to the tablet type. I love the salt system in my spa. I’ve had it installed for nearly a year now, and other than add some replacement salt, I haven’t had to touch it. I still test the water and shock the spa weekly. But my water balance is more steady, and the water feels and smells great! The best part? There’s no corrosion damage!
When fully inflated the hot tub has a diameter of 77-inches (note: there's a 85-in option) which gives its bathers a good seating position and enough legroom. The beauty of this feature is that it doesn’t consume much space compared to larger inflatable and non-portable hot tubs. As such you can place it even in your patio or a patch of grass in your backyard.

All top rated models come with a water filtration system to ensure that the water remains clean and fresh. This system is able to eliminate sediments and debris, making the use of the hot tub a safe experience. Also, it saves you time and money because tubs that do not come with this feature require you to change the water more often. Therefore, do not underestimate the importance of a water filtration system when you look for the best model to go with because it is mandatory for your health and well-being.
It isn’t designed to be left running 24/7, and will automatically shut off after around 48hrs. If you intend to make regular use of a hot tub and don’t want to have to keep waiting for the water to get back up to temperature, then a portable hot tub may not be the be the most efficient choice. If, however, you are simply looking for something to enhance your weekends, a portable spa is definitely the answer,

It is also a relief to know ahead of time the return policy and the manufacturer’s warranties. After all, this is an investment, and you don’t want to throw away your hard-earned money on something that will cause you more stress. You want a nice hot tub to de-stress in after a hard days work, and a reliable product will go a long way in assuring your relaxing time. The Coleman brand is leading the way in portable spas.
