Rated 5 out of 5 by from First time hot tub owners We're loving our HL 8.5 and use it every day. Each seating position offers a different variety of jets and massage areas. I find myself moving from seat to seat to experience them all. My wife works outdoors and really enjoys a hot soak after a day out in the cold. We're looking forward to watching the snow fall around us while we soak in hot, steaming water this winter! The tub is top quality and our dealer service has been excellent. Installation was easy and I'm getting a handle on water maintenance. We are very happy with our Master Spa and highly recommend the brand.

Rated 5 out of 5 by from Love it! We love our hot tub and use it almost every day. We have had it 7 weeks and I am very happy. I have drained it twice already for cleaning. Finding the happy medium for chemicals is tough but I think I’m getting a handle on it. Draining is easy but I wish the drain wasn’t under the outside panel. I think using a sup pump will be better. The jets are great. I love how I can adjust each one. It stays warm so it is always ready to get in. I love not having to wait to heat it up. I’m very happy with the cover lift. It is easy to use. Our electric bill went up about $35. It is well worth the $35. I thought it would be a lot more. I waited many years for my tub and it was worth the wait. We love it!

Rated 2 out of 5 by from Nice but not for the South We have had this new spa for 1 1/2 years now. We had a previous spa for 15 years so we are not new to spas. When we bought this one we knew we wanted the continuous pump circulation for continuous filtering and that is what we bought. However, we have been trying to figure out why the water in this spa seems to be always dirty. Our old spa stayed clean with that feature. Come to find out if you set the temperature down 3 degrees or more below the actual water temperature the continuous filter pump shuts off for 30 minutes to let it cool off. So if your in the South and set it way down to make sure the heat doesn't come on in the summer the filter doesn't ever run and your water gets nastier and nastier. There is certainly a programming flaw that doesn't provide for Southern cool water use. Beware.

Rated 5 out of 5 by from I love my hot tub! We are extremely happy wi5 our HL 8.5! It has great power and it’s so comfortable! We love that we can turn each individual jet on or off and that the jets are interchangeable. We can really customize each seat in the tub and it really makes the experience unique. We really like that Master Spa had 4 different lines to choose from because it gave us variety and a lot of choice. Didn’t feel like we we pigeonhole to one type. Just an overall great experience so far.

Rated 5 out of 5 by from Great tub...just what we were looking for After looking at 5 or 6 hot tub suppiers, we found the HL 8.5 was the perfect fit and our local provider was a geat team to work with.

Rated 5 out of 5 by from Love, Love, Love my Health & Leisure Spa! This spa is exactly what my family was looking for. The variety of jets in each of the four corners lets us customize any sore target areas. Some days we have to say "everybody switch!" every 10 minutes so we can all experience its goodness. This spa is very easy to maintain and customer service and representatives are top notch.

What is the ecopure filter replacement for this model? I can't seem to find that info anywhere.

Asked by: Darren
Hi Darren! It depends on the year of the spa and what type of filters you are using. We would currently use the X268532 Eco-Pur filter with the X268548 Outer White Filter. If you don't have a 2019 spa, please feel free to email customerservice@masterspas.com with the year of your spa and they can get double check those filter numbers for you. Hope this helps!

I keep getting heater flo fail error code. Temp. drops until I press aux. jet button or reset the temp. then it runs properly again temporarily. I replaced filters and still gett the error code. Why?

Asked by: dsperle
The first thing you need check is if you still get the error code with no filters in the spa. Check to make sure that there is nothing big in the spa that could get sucked down into the circulation system then remove the filters and clear the error code. If you are still getting the error code, then you will need to call us at (800) 860-7727 and we can walk through possible causes and get someone to service your spa. If there error code does not appear, that would indicate that the filters are dirty. We recommend that you clean your filters at least once a month in a filter cleaner solution that is carried by most spa stores. If your filters are constantly clogging than there is probably a water chemistry issue that we would need to discuss.
