It has 2 water treatment systems installed. The hard water treatment system keeps the water soft, which helps prevent the skin and hair from drying up. It also makes sure the unit remains in tip-top shape by preventing any chemical build ups which may damage it. We believe that this is an important feature, considering that this is a premium inflatable spa.
The jets are the ones that provide the soothing and relaxing hydro massages. To experience a truly unforgettable massage, you have to look for a model that features a large number of jets. A great choice for you is a tub like the SaluSpa Hawaii HydroJet Pro that comes with no less than 120 air jets and 8 hydro jets. It will soothe any muscle or joint pain that you feel due to the impressive number of jets that it comes with, and it will relax you beyond belief when you receive the massage as well.
Of all the inflatable hot tubs we did a review here, this is the only one that has the ability to run more than 1 function at the same time. This functionality is more than enough to convince some people to decide on buying this model, including us. Being able to run your heater while the bubble jets are running is an awesome experience. With bubble jets and the high-pressure massage jets turned on, everyone soaking can experience the massage they want all at the same time, whether light or targeted.
According to the Hot Tub Barn, there are a number of factors that benefit the body when it comes to relaxing in a Jacuzzi. One of the most obvious is the relive of stress, whether that’s after a long day or difficult gym session. Stress can cause muscle tension, headaches, fatigue and soreness. Secondly, it eases the pain of arthritis as it’s an excellent way to apply heat to the joints which can decrease pain and reduce stiffness. Lastly, in clinical studies, patients who used a hot tub lost slightly more weight without any diet or exercise programme. This is caused by the hot water simulating the effects of exercise on the muscles.
Water sanitation is very important. That is why every manufacturer made sure that all their inflatable spas come with a standard filtration system. This system helps keep the water clean by filtering away small debris, hair strands, and chemical residue. This is the part of the portable spa that you need to regularly maintain depending on your usage.
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.

Flimsy construction. Sources agree that inflatable hot tubs aren't very durable. According to the editors of HotTubSpaRatings.com, "as a shell material vinyl is easy to damage, especially if the chemical balance of the water remains out of ideal range for very long." Poor durability is one of the most common complaints about inflatable hot tubs in user reviews, though many also report better experiences. These tubs typically come with a one-year warranty.

The design and structure of the tub is just as important as the materials used to make it. Many manufacturers use a segmented inflatable design, reinforced with a vertical I-beam structure inside. These internal vinyl panels make for a sturdier tub, one that can support users leaning against it or even sitting directly on the outer wall of the spa. Premium portable hot tubs add another level of stability and protection with interlocking panels that surround the inflatable tub. Made of waterproof composite materials, these panels provide a rigid wall that protects and insulates the hot tub.
Welfare: for last, and surely not least, these tubs will offer what all hot tubs are meant to: a pleasant relaxing moment to chill out. While the massaging jet models are much more therapeutic as they can provide the benefits of hydro massage tubs, even the bubble models offer a relaxing and comfortable moment as they sooth the skin smoothly. You share all this with your relatives and friends as hot tubs make some of the best social gathering spots in any season. Who doesn’t love a chat immersed on bubbling hot water?
Small hot tubs that accommodate two adults and are designed for a more intimate experience measure about 3 to 4 feet high by 5 feet across and hold approximately 500 gallons of water. Larger hot tubs measure around 4 to 5 feet high and 6 feet or more in diameter and are built to accommodate up to 8 adults or more. They hold about 850 gallons of water.
Salt systems, for pools or spas, have trouble producing chlorine at low water temperatures. When water temperatures drop into the 60s, very little chlorine output is generated, even though your salt cell is working overtime. Many salt systems will shut down, in a self-protection mode, when low water temps are sensed. This of course, is not a big deal for spas and hot tubs, so long as you keep the water 65° F or higher. Do this, and you’ll have no problems.
Adding enough salt to reach 2,000-3,000 ppm in your spa takes about 2 lbs. per 100 gallons of water. The mineral in the water raises the buffering capacity of the water to resist changes in pH, alkalinity and calcium hardness levels. The addition of salt increases the total dissolved solids of the water, making the water less aggressive and more resistant to water balance fluctuations.
The Bestway SaluSpa Miami Tub is the best option for a good, not soak in the middle of winter. The secret to this tub’s winter worthiness is a rapid water heater that brings the 177 gallons of water up to 104 F. The smaller two-to-four-person size of the tub also lets the heater work quickly when fighting against the outside cold air. An air pump is included for quick inflation.
Considering the fact that this hot tub is inflating, thus easy to deflate and store away, you should not take risks and put it in storage during the cold season when it is not in use. If you do happen to need to use it, simply take it out of its storage place, inflate, and use it. Just do not forget to put it back in its rightful place when you are done using it to avoid any damage being done to its construction.
When you get the AirJet Spa, you can easily set it up by yourself without using any tools. You will just have to fill up the tub, connect it to mains, fill it up to whatever level you want with water, turn the heater ON and enjoy. So now that you know how simple it is to set up the tub, you should also know that even the tub is small, the company states that the tub is capable of up to 4 persons but I recommend you to get only 2 persons in because it isn’t a swimming pool after all.

One of the common gripes about these spa’s is the fact that when you use the bubble massage system you can’t use the heater at the same time. The bubbles have a 30 minute auto shut off and in that time the temperature can drop a few degrees. The bubbles going through the water can make it feel a bit cooler too. To be fair this is an issue with most portable hot tubs with bubble jets. It’s easy to switch the heater back on as soon as the bubbles are finished but the temperature only rises a few degrees an hour.

Maximum Heat Capability It shows what is the maximum temperature that the water can reach. When choosing the products, we made sure that they all feature a maximum heat capacity of around 104°F. This is the ideal temperature for the water to reach, being high enough for the experience of soaking in it to be as pleasant as possible without there being any repercussions.

The downfall would be the amount of time it takes the heat the water, even with the rapid heating system. This is a downfall that almost all of the inflatable tubs are going to have.  In 24 hours, the water will heat up to a maximum of 104 degrees. Some have reported that filling it with hot water to start off will raise the temperate in only six hours, but if you take this route, you’ll be spending more money on hot water.
