Far Infrared Sauna Buying Guide

Far infrared is the most common type of infrared heat in home saunas, and for good reason: it is gentle, efficient, and comfortable for long sessions. This buying guide explains what a far infrared sauna is, how to choose one, what it costs to run, and how it compares with full-spectrum cabins, so you can buy with confidence.

What is a far infrared sauna?

A far infrared sauna uses long-wavelength infrared heat to warm your body directly rather than heating the air around you. Because it works at a lower temperature than a traditional sauna, usually 120°F to 140°F, it feels milder while still producing a deep, full-body sweat. Far infrared sits at the long end of the infrared spectrum, which is why it penetrates comfortably and is the wavelength most associated with relaxation and recovery. Most home infrared cabins are far infrared, delivered through carbon or ceramic heating elements. If you want the full near, mid, and far range, see our full-spectrum infrared saunas. The Mayo Clinic reports no harmful effects from infrared sauna use in healthy adults.

How to choose a far infrared sauna

Focus on five things. First, heater type: carbon panels give even, efficient heat, while ceramic warms up faster and hits higher peak intensity. Second, EMF: choose a cabin with published third-party EMF readings, and compare our low-EMF infrared saunas. Third, size: match the cabin to your space and household, from a one-person unit to a three or four-person cabin. Fourth, wood: look for non-toxic kiln-dried cedar or hemlock. Fifth, warranty and support: a strong warranty signals quality. Our full infrared sauna buying guide covers each step in more detail.

Far infrared vs full spectrum

Far infrared gives you comfortable, everyday heat and is usually more affordable. Full spectrum adds near and mid-infrared wavelengths, which some buyers want for skin and recovery goals, at a higher price. If you mainly want relaxation, detox sweat, and a low running cost, far infrared is an excellent choice. If you want the widest wavelength range and are willing to pay more, consider full spectrum. You can read the deeper comparison in our full spectrum vs far infrared guide.

What does a far infrared sauna cost to run?

Running costs are low. Most far infrared cabins draw about 1,500 to 2,500 watts, so a 45 minute session costs only a few cents at average U.S. electricity rates, and a typical household spends well under 10 dollars a month. Far infrared uses roughly 75 percent less electricity than a traditional sauna because it heats your body instead of a large volume of air.

Frequently asked questions

Is far infrared better than full spectrum? Not better, just different. Far infrared is gentle, efficient, and affordable for everyday use. Full spectrum adds near and mid-infrared for a wider wavelength range at a higher cost.

Is far infrared safe? Yes, for most healthy adults used sensibly. Stay hydrated and keep sessions moderate. If you are pregnant, have a heart condition, or take medication, check with your clinician first.

How hot does a far infrared sauna get? Usually 120°F to 140°F, cooler than a traditional sauna, which is why you can enjoy longer, more comfortable sessions.
