So far, an excellent value, (year three update).
This is my review of the Intex 28431EP PureSpa Plus 85 Inch. First off, the 28431EP at $678 appears to be identical to the 28431E at $1024. I contacted Intex asking the difference and their reply "They are almost the same but the little difference lies in color. And the pool kind is the same but they are different pool sets and would come with different pumps and other maintainence kit. Have a good day." If true, I can't see the colour difference. The pump it came with is labeled 2843100B, and appears and functions the same as the higher priced model. All of the extras, cover, controls, tool kit, appear exactly the same as the model without the P. If there is $300 in less value here, I can't find it. So, about the spa itself. So far so good. Everything was well designed and very easy to set up. The quality appears top notch. Filled water started at 57°f and in 24 hours, was 100°f (my initial setting). The pump/heater is extremely quiet, something I was very surprised and pleased to discover. I have had the small Intex pools before and, as I recall, the filter was rather loud. Of course the air pump is louder but not too bad, about the same level as the bubble noise itself. As for those bubbles, the strength of the massage was completely unexpected. I thought the bubbles were more for appearance, but come to find out, they work exceptionally well. Feels great on the old back. Really glad I got the 85" model, 6 person is a bit of a stretch, but 4 close friends would be doable. For my wife and I, it's perfect. The cover is very well thought out, and looks to do a great job of insulation. The inflatable bladder, give the cover a bit of a dome and should prevent excessive water pooling with rain. My take so far, is save $300 and get the Intex 28431EP PureSpa Plus 85 Inch for $678. Very happy with this purchase. If anything changes, I'll update this review. --Mark Edit: Three weeks of steady, daily, use and the spa is working perfectly. Using the La Crosse Wireless Pool Thermometer, I can see the spa cycles 102° to 104° without any problem. The heating, actually runs less than expected. Consumers tracks my monthly power, so I'll report back with details. I'm old and my back hurts so the biggest problem so far is lifting off the insulated (very effective), cover. The cover that comes with this model, extends to the ground, and is quite heavy. When lifting, the fit is snug, so you're fighting a vacuum to get it off! Easy solution though. When you go to remove the cover, undo the encircling strap, start the air pump, and the cover domes and easily lifts off! 😎 This also allows any rain water to drain off the top. Super easy. I generally take the insulated cover off for a morning soak, leaveing it off all day, using only the inflatable bladder. This seals well and keeps leaves and junk out of the water. Easy on and off makes it simple for a quick soak. I put the cover back on at the end of the day, or if we go away. When I originally fill the tub, I used a garden hose that was a couple years old, and the water was nasty. The hose must have deteriorated. Anyway, took several days and a couple of filter changes, and the pump/filter cleaned the water gin clear. Testing also showed are water was extremely hard. This unit supposedly had some method of softening water, well 8 days in, it tested perfect. With a few other standard pool chemicals, everything balanced out nicely. I check and clean/replace the filters every few days. They clean off well, especially with a bit of compressed air. You should get a fair amount of use before replacement is necessary. I also purchased the Intex 28620EP Handheld Rechargeable Spa Pool Vacuum. Maybe not completely necessary, but makes cleaning extremely easy. I think I read somewhere that the filter/heater timed out after 72 hour, or so. Not the case so far, but I use the spa daily. All said, very pleased with this spa. Stay tuned. Edit: END OF THE SEASON So, it's only mid October, but took advantage of one of the last nice days to store the spa. Read the instructions for storage, and it's pretty simple. Drained with the a hose a instructed and finished up with a wet vac, wiped down and deflated with the air pump. This work really well and collapsed the pool enough that it actually FIT into the provided storage bag! Other parts stored in the original box. Season summary: I used this spa almost daily for just shy of 6 months and enjoyed every minute. One E-90 filter error, when first installed with nasty water from an old hose. New filters and the water cleared up quickly and everything ran perfect all season. At first I was cleaning the filters, to extent there use, but found one one of them really doesn't do anything so just changed them weekly, swapping one with the other at that time. I am guessing the dual filters are a legal requirement, but for a spa this size, not really necessary. My only disappointment is the 104° temperature limit. I understand this is also a legal (or at least industry) requirement, but wish it was just a degree higher. I have a recording temperature gage and the spa consistently cycles between 102° and 104° which is good, but 102° is just a bit low for my taste. My friend has a $44,000 dollar spa and his does the same, so, I guess I can live with it. My electric usage was slightly higher than last year, but not by much. I am sure the spa accounted for some, but too little to put a number on it. As I was storing the spa and components, I had an opportunity to inspect everything. My original hope was to get a couple years out of this. I now suspect I can do much better as everything appears to be in excellent shape. Only a small amount a fading on the dark blue inner wall, otherwise all looks good. It's too bad that Amazon no longer allows replies on product reviews. Would love to compare notes with other spa owners. Summary: Absolutely an excellent value. See you next year, stay warm. Edit: Beginning year three, still good with one problem. At the end of year two, the insulated cover was finished. Started ripping at the seems. Intex does not seem to offer a replacement, so I irer the non-insulated "shorty". Actually, while not as efficient, it sure is easier to deal with. So, as a compromise, I'm happy, (see photo with shorty cover). Otherwise the spa has performed perfectly. Incredibly good deal and a pleasure for daily three (mostly) season use. Recommended.

A fabulous self care item!
I ordered this in 2022! I’m now a 72 year old senior female. When it arrived, I set it up all by myself. I have now enjoyed it for several years. It’s on a covered patio in Palm Springs CA area. It’s so easy to maintain and clean. Just make sure you change the filters when needed and change out water at least once a year. I use a little thing with Bromine tablets in it and shock once a week. I have noticed no electric increase as a result of it and it’s on 24/7. I have to say that I’ve purchased thousands of products on Amazon over the years and this has by far been my greatest investment. I was in it tonight and knew that I had to write a review, which I don’t do. It’s so affordable for the value you get. Good for joints. The bubble jets are powerful and quite frankly, it’s as good as the community hot tub which is right across the street from my house in a 55 plus community. I can’t say enough good things about it. I e not had a single problem with it and I e used it everyday since I got it in 2022. The cover keeps it clean even in our sand storms here in the desert! Thank you @Intex for making such a great product! Please keep the filters affordable for us seniors. PS: When I bought it, I thought it would last two years and here I am, going on 4! And, if you want company, even though it says six, it will fit four comfortably. I use it with cool water in the summer. If you want a portable hot tub, easy, affordable solution to for indoor or out door luxury that keeps it temperature and stays inflated, this is the one to pick!! Sorry for long review but great products deserve it!

Constant e90 errors on new hot tub
We used to have an inexpensive off brand hot tub which had lasted for many years and was great. After moving we purchased this hot tub as it is one of the largest inflatable ones available and we wanted the extra room. Although it's awesome when it's working, we get e90 errors constantly. The e90 error appears as an indication that water flow os restricted which can be from dirty filters or water level being too low. To be fair, we tried purchasing the off-brand filters at first but afyer getting the errors a few times we switched to the intex branded ones to see if that would fix the issue. Even with sufficient water levels and intex branded filters, we get an e90 error daily which, especiallt in the winter, will mean the pump/heat turn off and the temp will drop. The manual suggested unplugging the pump for 30 minutes to clear the code but that didn't resolve the consistent errors either. Minus the pump constantly turning off, it's a great hot tub so maybe we just got a bad pump delivered but for almost $700 I feel like it should be top-of-the-line and shouldn't be shipped with potential issues like this.

Nice Hot Tub for Small Space
This was our entry into the hot tub world. We didn’t want to spend a lot of money and we had limited space. This was perfect. It fit nicely on our patio. It holds about 200 gallons of water, but fills up very fast. The set up time took about an hour. Instructions were very clear and simple. We purchased additional seating, but they are not needed and we rarely use them. The cover is very durable and well made. It holds the heat for a long time. The controls are easy to use. I purchased a 3” chlorine tablet and float ($10) instead of the little 1” tablet it came with. The side are very strong which surprised me. We change the water and replace the cheap paper filter monthly. The light is cheap and dim but we don’t use it anyway (can prob find a replacement on Amazon). It says 6 person tub which translates to 4 adults comfortably with legs crossed. My only complaint is that the jets are full power or off, not adjustable. They are loud so a lower setting would make conversation better.

Nice and big!

This is a really sturdy product. Easy to get operational. I am 5’ 10” and can lie flat. 4 adults could sit in it but you wouldn’t get your legs stretched I imagine. Bubbles are strong and having moved from a real hard sided spa with directional jets I am more than happy. I had an issue with my cover and it was resolved within a weekend by Intex customer service who were great.

Wrong lid can't fill bottom with air pump broken

It was easy to set up. Heated well. But it lacked some quality. One of the fittings was so out of alignment it leaks. This was not because it wasn’t level, it’s because they don’t line up. The fittings are on flex hose so designed to take into account some miss alignment yet it was so out it still didn’t seal. Not that big a deal when I drain it next I’ll just direct connect a piece of hose with hose clamps. Still a little disappointing.

I bought it and received it 20 hours after the purchase. Very easy installation, and i am surprise for the price. Buying an inflatable hot tub my expectations were mid low, but it really is as nice as a 8000$ hot tub. I just don’t know how much time it takes to heat it up, started the water heater at 39F. Recommend the seller and the product.
