Ratings that Affected the Ranking

When we started writing this article, we had to establish certain rating criteria to help us separate the best from the rest. Also, after finding the best products on the market, we had to rank them according to their quality. In this section of the article, we will show you how we rated the infrared sauna slim belts, thus offering you a better understanding of why our top looks the way it does.

  • Recommended Maximum Waist Size

  • When we ranked the best sauna slimmer belts on the market, we wanted to make sure that they would cater to the needs of all people. Thus, we had to pay attention to the maximum waist size that is recommended for each model so that as many people as possible can wear the belts. When it came to this rating criteria, the model that received the most points was the HealthyLine Healing Belt with Photon Lights as it can be used by people who have a maximum waist size of 52 inches.

  • Wave Length Range

  • The wave length of the infrared rays shows how safe the product is for the wearer’s health. Thus, we made it a point for all of the infrared belts in this top to boast small wave length ranges in order to not exist any dangers when wearing them. As you can see, the maximum wave length of most of our models is 14 µm, which is extremely low.

  • Build Quality

  • Obviously, we had to deliver belts that boast a high-quality construction to ensure that they will be in a perfect shape even after years of intense daily use. From this point of view, all of the models featured in our top have received high ratings as the materials that they’re made from are durable and they ensure the safety of the wearer.

  • Adjustable Temperature

  • For the belts to suit everyone’s preferences when it came to heat tolerance, we made it a point for all of them to feature adjustable temperatures. Therefore, regardless of what infrared belt we’re talking about featured in the top, you will notice that there is the possibility to adjust the temperature according to your preference for the experience of wearing it to be pleasant and comfortable.

  • Timer

  • As we have already said, the timer is by far the most important feature when it comes infrared sauna slim belts. The reason why it’s so important is that it ensures that an accidental overuse that might lead to the wearer getting hurt won’t occur. All of the models featured in our top come with timers that the users can set for as long as they like in order to ensure a safe and successful operation.

  • Warranty Length

  • The length of the warranty is another criteria that affected the ranking system as it shows a lot about the quality of the product and how much the manufacturer trusts it. Not only this, but the warranty shows for how long the belt will be replaced or repaired free of charge. The only model that received a negative feedback when it came to this aspect was the Under the Sun Sauna Belt Far Infrared as it is backed up by the manufacturer for only 90 days, a lot less when compared to the 1-year warranty of the other models.

Buying Guide

Want to make sure that the infrared sauna slim belt you invest in will surely be of an exceptional quality not only when it comes to the materials that go into its manufacturing but to the quality of its performance as well? Then read this useful buying guide to know what are the elements that you must look into when making the purchase.

  • It Must Have the Appropriate Length for You

  • The most important spec that you have to look into when making such a purchase is for the length of the belt to suit the length of your waist. What’s preferable is for this length to be bigger than the size of your waist to ensure a good fit. Seeing how most of these products tend to be compatible even with the waist size of overweight and obese people, you won’t have a hard time finding the right one for you either in case you’re on the heavier side.

  • Possibility to Adjust the Belt’s Length

  • Another crucial feature to look into is whether the length of the belt is adjustable or not. As time passes and you make it a routine to wear the belt, you will lose weight. Thus, your waist will become smaller, a moment when you need to adjust its length so that it may offer a comfortable, snug fit. Also, most people who buy sauna belts buy the products not only for them but for other household members to use. Thus, it’s important for the size of the length to be adjustable so that more people can use it without a problem.

  • It Should Feature the Timer Function

  • By far, the most important feature that the wearable must come with is the timer. Not only does it make wearing the belt more convenient, but it raises the belt’s safety in use as well. The timer makes the operation more convenient as it automatically shuts the sauna belt off when the operational time that you have set passes. When it comes to increasing safety in use, it helps as it ensures you won’t overuse the product accidentally by not paying attention to how much time has passed since you put it on.

  • The Temperature Range Should Suit Your Preference

  • Although we write last about the temperature range that the sauna belt boasts, this doesn’t take away from the importance of the spec. The truth is that some people have a higher tolerance to heat while other can’t really stand high temperatures. Depending on which category you fall, you should buy a belt that suits your preferences. In case you don’t plan on using it alone but rather share it with other household members, make sure that the infrared belt boasts a generous temperature range in order to suit everyone’s personal needs.
