The salt cell used for saltwater hot tubs is a titanium coated electrolytic cell, which will eventually lose enough of its coating to stop producing enough chlorine. Spa salt cells usually last 2-5 years, depending on the model. At that point, you can replace just the cell (not the power supply). Keeping your cell clean (some models are self-cleaning), and not using it for cold spa water (below 60° F), are key to a long cell life.
This Coleman inflatable hot tub as 120 bubble jets installed at the bottom. They are designed to suck in air from the outside and blow through the water. This means turning on the bubble jets can lower the water’s temperature. We advise to heat up the water several degrees higher than your preference before taking a dip to address this shortcoming.
The exterior is made from a specially coated fabric that is suited to withstand the outdoor elements. It is the classic Coleman-brand green. (This is usually their hallmark color for many of their products.) It also comes with a green fabric cover that is lined with aluminum material. The aluminum coating serves to keep the water warm while you’re waiting to jump in.
The Pump in the AirJet is designed at such a place that it becomes easier for you to reach it while still in the tub so that you will not have to be interrupted in the middle. The pump actually has a Heater combined with it to serve Warm Water without making any of extra sound. So as the pump is placed near to you, it was necessary for them to take care of the noise made by the pump and believe me when I say pump makes the least noise possible giving you the best experience.

Cover: if you spot a model that includes the cover, it is a plus, however don’t take the cover of an average model as an advantage just because it has a cover. They are quite important to keep your tub not only hotter for longer but also to protect the water from getting contaminated with sitting dust and any other contaminants from the air, from leaves to insects that may be really looking for water. Most brands that don’t include the cover sell it separately.
One of the problems of this bath tub is the material that is used to manufacture it. As mentioned above, inflatable hot tubs are flexible and easy to carry but it is these same properties that make it vulnerable to various elements. Sharp edged objects lying around the house as well as elements in nature such as thorns and stones pose the risk of damaging the hot tub. Once the hot tub is perforated, there is almost no way of restoring it to its previous glory. Additionally, these bath tubs can only be utilized to a certain extent after which the wear and tear makes it necessary to look for a replacement. The disadvantage of owing an inflatable bath tub is that you have to take utmost care in protecting it from natural elements and climatic factors that might damage it.
They don’t usually use real water jets, but instead use fans to “blow” the air around (also because of the 120 volt outlet), which causes them to cool down much faster than a regular hot tub. This cooling effect is only made worse by the fact that the materials they are made from lose heat much faster than the materials used on a regular hot tub. All in all, you aren’t likely to get more than 15 minutes to a half an hour of good heat out of an inflatable hot tub.
