Our Maxwell saunas and Wearwell outdoor saunas are equipped with ultra-low EMF heaters, and their EMF readings range from 0.1 to 1.0mG. While other saunas have EMF readings between 10~30mG, there is no need to be concerned about this non-ionizing radiation, as it is comparable to that emitted by electronic devices such as cell phones. This is considerably lower when compared to the levels of 100+ mG often found in many other sauna brands, regardless of the particular model.

A U.S. Patent for an infrared sauna with low electric field and low electromagnetic wave radiation has been registered for our Maxwell infrared heater. Our technology integrates both extremely low frequency (ELF) electric field and low electromagnetic field radiation (EMF) without the use of any shielding material.

The 149F limit is an ETL safety standard built into the control panel. The 149 setting is perfect for prolonged infrared therapy sessions (up to 60 min.) while also taking user safety into account.

The temperature shown on the control panel represents the surface temperature of the infrared heating plate. If it displays 149F, the actual room temperature may have reached 180F. However, this is also dependent on the initial ambient temperature.

Ignoring the environment, the rate at which the sauna heats up is directly related to the power of the heating panels, but inversely related to the room of the sauna space. As a general guideline, it typically takes around 20 minutes to heat up from room temperature to 149F. However, if we consider the current temperature conditions, it will only take 15 minutes on a hot summer day and can take up to 30 minutes on a cold winter day. Additionally, the frequency of opening the door affects the temperature inside the sauna.

A good infrared sauna will not overheat your lungs. Ideally, you go inside when it’s only 25-28C (77-83F) and let the heat slowly rise while you sit inside. That way your body adapts to the rising heat. Once you start sweating, around the 37C mark (98.6F), you only need to stay inside a little while longer. Most people come out between 42-50C (108-122F).

When you choose between the 906MH and 906MB, you will find that the 906MB uses basswood in addition to not having a heated front door. Basswood is the better choice if you want to put the sauna under a patio with a cover. And there is no heater for the front door to prevent moisture. If you don't care about wood, you can choose the 906MH because it has an extra heating panel on the front door to get an all-around sauna experience.

When you are shopping for an outdoor sauna, you will find that we have 4 types of wood: Fir, Basswood, Mahogany and Red cedar. If we rank them in order of durability, the results are as follows: Red cedar = Mahogany > Basswood > Fir. Of course, all saunas are sturdy and can withstand heavy storms and snow directly. Basswood, Mahogany and red cedar are better suited to withstand heat and moisture without warping or cracking.

Fir is a type of softwood but relatively strong and durable. And Fir is lighter in color with small tight knots that give its rustic appearance. It is known for its stability and resistance to decay, making it a popular choice for outdoor construction projects. When used in saunas, fir provides a warm and inviting aesthetic.

On the other hand, basswood is a type of hardwood that is heavier in weight compared to fir. It has a pale yellow to light brown color with a fine and even texture, lack of knot. Ext durability testing conducted by the research and development department has revealed that basswood is both highly stable and cost-effective for long-term use. Moreover, basswood is hypoallergenic, making it an ideal option for individuals with sensitive skin.

Mahogany is a hardwood with a rich, reddish-brown color. It is known for its durability, strength, and resistance to decay and insect damage.

On the other hand, red cedar is also a durable wood with natural oils that provide it with inherent resistance to decay, rot, and insects. It has a distinctive reddish-brown color with a pleasant aroma.

Ultimately, the choice of wood depends on personal preference, budget, aesthetics, and specific needs for the sauna.

Yes, it can, as long as the top and interior don't get wet. You have to pay attention to the absolute rain protection of the top and bottom for an indoor sauna. Because the top panel of indoor sauna has wires, and the bottom has no raised and waterproof base.

Humidity has very little impact on the sauna, and if you can open the sauna weekly and let the heating panels work, this will prevent the moisture from deteriorating the appliances and wood.

While the outdoor sauna has more comprehensive waterproof protection. SalusHEAT outdoor saunas have even less impact because of the added water barrier and the sealant on windows.
