Intex PureSpa Bubble Massage Spa models 28409E and 28431E are modifications of one model with slight differences. So, all characteristics will be reflected in one description with the highlight of the differences.
These spas are designed to relax six people with the touch of one button. One control panel adjusts the temperature in the range of 68-104 F, turns on 170 bubble jets, and starts water circulation. With a water circulation system, the built-in hard water treatment system starts to work, making water gentler for the skin. You can lay down in the spa, put your head on the headrest cushion and get an enjoyable refreshing massage from 170 bubble jets; to make the experience more memorable, you can turn on LED lights.
Also, the system allows you to adjust the temperature based on your personal preference. If you want only to dip your feet, the patented Fiber-tech construction system of the walls is strong enough to sit on the walls.
Before using the spa, please check all warnings indicated in the manual. The spas can’t be used at a temperature less than 40 F as water can freeze inside the circulation system. You need to partly inflate/deflate the spa tub walls during cold or hot temperatures as air expands during the midday heat, and the spa is less inflated at colder temperatures.
A detailed manual makes installation, maintenance, and usage processes easy. The spas are designed for a durable flawless relaxing experience. Inside the package, the carry bag is included for transportation and storage while the spa is deflated. The transportation of a full spa with water is not recommended.

Intex 28409e and 28431e are simple in operation hot tubs with easy maintenance; with one push of a button, you can tilt your head back and enjoy the inflated headrests. Please see their face-to-face comparison below to check which models are more enjoyable.
Design and Dimensions
The PureSpa 28409E and 28431E models have a round shape with the same diameter of 85 inches and a height of 28 inches. The inflatable spas have two colors but are colored differently. Both models have navy blue outer walls, while 28409e has white and 28431E has navy blue inner walls; the upper part of the walls and two headrest inflatable cushions are white for both models.
The control base with a pump, heater, blower, and built-in hard water treatment is installed on one side. The navy blue insulated cover is supplied to protect the spa from precipitations and debris and keep the water warm. The cover has an inflatable bladder and buckles with keys that connect the cover and securely protect the spa from kids. On the outer surface of the walls, several grab handles are ensured for spa moving.
verdictAs there are no considerable differences between the models color patterns and the size is the same, this part of the comparison has no winner.
Materials
The PureSpa models are made from puncture-resistant 3-ply laminated material and strengthened by Fiber-Tech construction of 54 beams. The construction is strong enough to sit on the side, dipping your feet in hot water. In addition, the material is durable and easy to maintain. You can purchase a separate Hot Tub Maintenance Kit with a curved brush and mesh skimmer net to collect all debris and scrub the interior wall surface from dirt and grime. In case of rupture, repair patches and swatches are available on the market.
verdictThe material of Intex PureSpa 28409E and 28431E is the same. So, there is no winner.
Filtration system and maintenance
The spa owner of 28409E and 28431E should regularly check the quality of the water. Regularly adding sanitizer or other chemicals to control bacteria and viruses in the water is recommended. Safe, clean water ensures long spa life. All chemicals (including the chlorine dispenser from the package) should be added when the spa is not occupied. The floating chlorine dispenser should be used for one chlorine tablet administration in the spa water.
Most inflatable Intex spa models have a filtration system consisting of two easily replicable filter cartridges (type S1) for cleaning spa water. Filters should be inspected and cleaned once a week and changed once a month. The spa water should be changed every 2-3 months when it becomes cloudy and does not clean anymore by chemicals.
Water is considered safe with the following characteristics:
- pH – 7.2-7.8
- Total Alkalinity – 80-120 ppm
- Free chlorine – 2-4 ppm
- Calcium hardness – 100-350 pp
- Water temperature 68-104 F
If the heating system is activated, the filtration system automatically starts. The particular water filter button is provided on the control panel to start it manually.
The electronic hard water treatment to reduce calcium creation and increase the efficiency of the spa works in conjunction with the filtration system. On the LED screen the water filter icon shows then the system is activated.
verdictAs both models have absolutely the same filtration system and maintenance requirements, there could be no winner in this part of comparison.
Pump
The control unit for these Intex spas is a multi-functional device on one motor: a heater with 1.300 Watts power; a bubble air blower with 800 Watts power; a filter pump with 460 gal/hr flow rate and electric hard water treatment – 10 W. Overall the spa draws 13 AMPS, to prevent any risks of fire the control base should be connected to circuit breaker without extension cords and any other electric consumers. The electric power cord is GFCI/RCD type and should be tested before each use.
The length of the cord is 25 feet. The filter pump allows twice spa water circulation for one hour. The motor works quietly, it will hardly disturb you while the tub is bubbling.
verdictThe essential part of each spa – the control unit with a motor and a pump – is the same for these Intex spas. Again, there is no winner in this part of the comparison.
Control panel
The control panel on 28409e is lifted for better accessibility to the level of the human eyes while sitting in the tub. On 28431e, the control panel is integrated into the control base. Both control panels are protected with a plastic lid.
The number of buttons on both panels is the same: temperature regulations (up and down), power button, temperature switch from Celsius to Fahrenheit, and separate control buttons for heating, water circulation, and bubbling. You can see the current temperature and working mode on the LED display.
verdictThe control panel’s location influences only the spa’s usability. In this comparison, the solution in the 28409e model looks more preferable, so it is the winner.
Temperature
Both hot tubs are designed for working only at safe temperatures between 68 – 104 F. The start temperature should be at least 50 F for the outdoor installed spa to achieve maximum temperature. The heater raises the temperature by 1-2 F/ hour. If you use the spa constantly, you can keep the heater always on and close the cover. As a result, the water will be warmer for a longer time. The initial heating can take up to 12 hours and depends on the ambient and initial water temperatures.
verdictOnce more, there is no winner as these hot tubs are designed to work at the same healthy temperatures and equipped with the same heater to warm the water.
Bubble jets
On the interior wall of 28409E and 28431E models near the bottom, 170 little holes are located. Through these holes, powerful bubble jets are created. You can turn on and off the bubbles from the control panel using only one button for all. Also, when you make chemical treatment of the spa, it is recommended to turn on the bubble mode (automatically turns off after 30 minutes) for the quicker dissolution of chemicals. A bubbling system should be used while the spa is covered, as air can accumulate inside the spa and damage it.
verdictThe bubbles for both models are produced with the same powerful bubble air blower in the control unit. The number of jets is the same so this section could be no winner.
Draining
There is no difference in the draining system of Intex 28409e vs. 28431e either. The drain valve cap is on the bottom of the spa near the inlets for the control base. You should attach the garden hose and point the other end to a suitable draining area. Another drain valve cap should be opened inside the spa tub after setting the hose to start water flowing out. The bubble button should be pressed while the control unit is disconnected from drying out the piping system. Before storing the spa, all accessories and the piping system should be drained.
verdictAs there is no difference in the draining system, there is no winner.
Assembling
There is no procedure or time difference in assembling Intex 28409e vs. 28431e. For spa installation, only one person is required for 20 minutes.
The setup process has several stages:
- Open the carton boxes and take out all details.
- Move the spa tub to the desired installation place. Set there the control unit and the tub on the insulated cloth.
- Connect the control unit to the electricity. Inflate the spa tub walls and spa cover air bladder using an inflation hose.
- Connect the spa unit to the spa tub. Attach two filter assemblies—close bottom drain valve cups.
- Fill the spa with water. You may use a garden hose.
- Press the button to heat the water. After the water achieves a comfortable temperature, you may enjoy the spa.
Some requirements for spa installation (check them before purchase):
- Both tubs should be set up on a leveled, flat surface capable of handling the spa’s weight with water and six adults (around 6000 lbs or 2700 kg).
- The floor should be water-resistant and non-slippery.
- The spa could be installed indoors or outdoors with enough space around to execute proper maintenance. If you install the spa indoors, the room should be adequately ventilated to prevent excess humidity. If you install the spa outdoors, the spa should not be placed under direct sun for an extended time.
- There should be no sharp objects under and around the spa.
- All electrical devices and metal surfaces should be at least 5 feet away to prevent electric shock.
- The power cord should be plugged without extensions into a grounded electrical socket.
- The spa should be installed on an insulated ground cloth to prevent heat loss.
verdictThe installation process of Intex 28409e and. 28431e is super easy and consists of the same steps. There is no winner.
Accessories
In the package of both models, Intex 28409e vs. 28431e, 1 multi-colored LED light (4 colors) is included creating a unique ambiance. The lights work from 3 AAA batteries that should be purchased separately. Two buttons control it on the light itself.
Intex 28409e also comes with two attachable cup holders and refreshment trays. However, for 28431e, you need to purchase them separately.
Also, you can purchase for both models slip-resistant spa seats that can raise a person’s height for 3 or 5 7/8 inches to sit more comfortably.
verdictIntex 28409e is the winner in this comparison, as two cup holders are included in the package.
