Buying Guide: What to Look For

EMF & ELF Levels

EMF (electromagnetic field) exposure is a major concern for health-conscious buyers. Look for saunas with independently tested EMF levels under 3 mG. Clearlight leads with virtually zero EMF, while Sunlighten is acceptably low.

Infrared Spectrum

Full-spectrum saunas (near, mid, far infrared) offer more versatility than far-infrared only. Near IR benefits skin and cells, mid IR helps with inflammation, and far IR penetrates deepest for detox. Premium models offer all three.

Size & Capacity

Measure your space carefully. 1-person saunas need about 4x4 feet, while 2-person models need 5x5 feet or more. Consider ceiling height too—most saunas are 75-77" tall. Corner models save space.

Build Quality

Cedar, basswood, and eucalyptus are the premium wood choices. Avoid particle board or low-quality imports. Look for eco-certified, sustainably harvested wood with antimicrobial properties.

Warranty

A longer warranty indicates manufacturer confidence. Clearlight's lifetime warranty is industry-leading. Most quality brands offer 5-7 years. Avoid anything under 3 years.

Assembly & Electrical

Most infrared saunas use standard 120V outlets. Larger models may need 240V or a dedicated circuit. Assembly typically takes 1-2 hours with buckle or snap-together panels.

Infrared vs Traditional Saunas

Many people wonder whether they should choose an infrared sauna or a traditional Finnish sauna. Here's the key difference:

wavesInfrared Saunas

• Operate at 100-150°F (lower temps)
• Direct infrared heat penetrates 1.5" into body
• More efficient sweating at lower temps
• Easier to install (120V outlet)
• Lower operating costs
• Better for those who can't tolerate high heat

local_fire_departmentTraditional Finnish

• Operate at 170-200°F (high heat)
• Heat the air which heats your body
• Authentic Finnish experience with löyly (steam)
• May require 240V electrical
• Higher operating costs
• Used in most research studies

Our take: For home use, infrared saunas offer the best combination of convenience, safety, and health benefits. Traditional saunas are great if you want the authentic experience and have the space/electrical capacity.
