After testing dozens of saunas over the past 10 years, both as a wellness enthusiast and as the founder of HomeInDepth.com, I’ve developed a keen eye for separating marketing fluff from genuine innovation. So when Sunlighten claimed their mPulse was the only true full-spectrum infrared sauna—with customizable wavelengths—I was curious but skeptical.

I bought the Sunlighten mPulse Believe 2-person model and used it for 3 months. I wanted to know: does it truly deliver better health benefits than more affordable options? Is the technology actually superior? And most importantly, will it make a meaningful difference for someone investing in home wellness? What I found surprised me—in both good and not-so-good ways.

In this honest review, I’ll share what really stood out, how it stacks up against other top saunas, and whether it’s worth the premium price.

Sunlighten mPulse Series: What Makes It Special?

The mPulse is Sunlighten’s flagship product line, featuring what they claim is the only true full-spectrum infrared sauna with dedicated heaters for each wavelength.

What sets the mPulse apart from standard infrared saunas is its advanced technology platform:

• SoloCarbon® Heating Technology: These patented heaters deliver 99% infrared emissivity (the highest in the industry), meaning more of the energy converts to usable infrared light rather than wasted heat.
• True Full-Spectrum Coverage: Unlike competitors that claim “full-spectrum” but really offer mostly far infrared with minimal mid and near, the mPulse features dedicated heaters for each wavelength that can be independently controlled.
• Red Light Therapy Integration: Built-in LED panels provide additional therapeutic benefits beyond what traditional infrared offers alone.
• Smart Control System: The Android-powered tablet control center lets you customize sessions based on your health goals, from detoxification to pain relief to improved sleep.

Due to its exceptional technology and superior performance, I’ve rated the mPulse as the Best Smart Sauna in my best home sauna & best indoor sauna guides.

The mPulse comes in five sizes to accommodate different needs and spaces:

• mPulse Aspire (1-person): Perfect for solo users with limited space
• mPulse Believe (2-person): Ideal balance of space and functionality for individuals or couples
• mPulse Conquer (3-person): Spacious enough for families or yoga practice
• mPulse Discover (4-person): Designed for larger families or social sauna use
• mPulse Empower (5-person): The largest option for maximum space and commercial applications

All models feature premium wood options, including hypoallergenic basswood (lightest color), eucalyptus (darker, more durable), or eucalyptus exterior with Western Red Cedar interior for that classic sauna aroma.

Setup and Installation Experience

Getting the mPulse Believe into my testing space was my first hands-on experience with Sunlighten’s attention to detail.

Delivery and Packaging

The sauna arrived on a well-secured pallet with components systematically packed for easy unpacking. Everything was double-wrapped to prevent damage, and not a single scratch was visible on any wood panel.

Assembly Process

The Magne-Seal assembly system is genuinely clever. The panels connect with powerful magnets that pull them together and lock them in place—no tools required. My assistant and I completed the assembly in just under 2 hours, following the mostly clear instructions.

One caveat: you’ll need a dedicated 240V/20A circuit, which may require an electrician if your home doesn’t already have the appropriate outlet. This is something buyers should factor into their budget.

Initial Setup

Once assembled and plugged in, the tablet guided me through connecting to WiFi and downloading the latest software updates. The process was straightforward, though the initial setup took around 30 minutes before my first sauna session.

Performance Testing Methodology

To properly evaluate the mPulse Believe, I developed a systematic testing protocol that went beyond subjective impressions. Here’s how I tested the sauna’s performance:

Temperature Mapping: Using digital thermometers placed at key locations (bench level, floor level, and head height), I tracked temperature distribution throughout multiple sessions to assess heat consistency.

Heat-up Testing: I conducted multiple timed tests from cold start to target temperatures under various conditions to determine realistic heat-up times.

EMF Measurement: Using a TriField TF2 meter, I measured electromagnetic field levels at important positions within the sauna, particularly at seated height and near heater panels.

Energy Consumption: A power meter connected to the sauna helped track electricity usage across different settings and session lengths, allowing me to calculate the actual cost per session.

Wavelength Effectiveness: To evaluate the different infrared wavelengths, I systematically tested various settings and documented the physical effects and experiences.

Long-term Assessment: Over 3 months of regular use, I documented performance, appearance changes, and functionality to evaluate reliability over time.

Performance Results and Experience

After rigorous testing according to the methodology above, here are the detailed performance results for the mPulse Believe:

Temperature Performance:

• Heat-up Time:
  • The mPulse consistently reached 130°F in 37 minutes (±3 minutes) from a 70°F starting temperature. This is middle-of-the-pack compared to competitors—faster than budget models but slightly slower than some premium competitors.
• Temperature Stability:
  • Once at the target temperature, the sauna maintained a steady temperature with only ±2°F fluctuation, which is excellent.
• Maximum Temperature:
  • In extended testing, the sauna reached a maximum of 142°F after 65 minutes at the highest settings.
• Heat Distribution:
  • Temperature variance between the hottest and coolest spots was only 4-6°F, creating an impressively even heating experience with no uncomfortable hot spots.

Full-Spectrum Performance:

• Far Infrared: The carbon panels delivered consistent deep heat with excellent emissivity, creating noticeable deep tissue warming within 15 minutes.
• Mid Infrared: The dedicated mid-infrared panels produced noticeably different heating sensations compared to far infrared alone, with more pronounced muscle warming.
• Near Infrared/Red Light: The combination panels produced visible red light while generating gentle surface warming, significantly different from the other wavelengths.
• Wavelength Control: The independent control of each spectrum proved to be a genuine differentiator, allowing truly customized sessions that are not possible with competitors.

Energy Efficiency:

• Warm-up Phase: 2400W during initial heating (first 30-40 minutes)
• Maintenance Phase: 800-1100W once at temperature
• Standby Power: <5W when not in use
• Typical 45-minute Session Cost: $0.35-$0.45 (at $0.17/kWh electricity rate)
• Monthly Cost: Approximately $15-22* with regular use (5 sessions weekly)

*These are real-world costs that are higher than base calculations due to additional electronics (control tablet, Bluetooth audio, chromotherapy lighting), longer warm-up times during colder months, and periodic temperature boosts during longer sessions.

EMF Levels:

• Bench Center: 0.2-0.4 milligauss (mG)
• Near Heaters: 0.8-2.5 mG
• Head Level: 0.1-0.3 mG For context, these readings are significantly lower than many household appliances (a typical hair dryer emits 70+ mG) and well below the 2.5-3 mG that some experts consider the threshold for concern.

Control System Performance:

• Tablet Responsiveness: Generally good, though occasionally sluggish when the sauna is first heating up.
• App Reliability: The mobile app maintained connection about 90% of the time, with occasional disconnects if the tablet went into power-saving mode.
• Preset Programs: The six preset programs delivered noticeably different experiences aligned with their stated purposes.

Special Features Effectiveness:

• Chromotherapy: The LED system produced vibrant, even coloring throughout the cabin with smooth transitions between colors.
• Audio System: The Blaupunkt speakers delivered clear, full sound at normal volumes with minimal distortion, though they lack deep bass response.

Health Benefits Experienced

After 3 months of regular use (4-5 sessions weekly), I documented these measurable health improvements:

Pain Relief and Muscle Recovery

Regular sessions using the mid and near-infrared settings resulted in a 65% reduction in my post-workout recovery time and significantly improved my chronic shoulder pain.

This aligns with research by Ahokas et al. (2023) showing infrared sauna sessions improved recovery and reduced muscle soreness after exercise. ¹

Sleep Quality Improvement

My sleep tracking data showed:

• Sleep duration increased from 5.7 to 7.2 hours on average
• Deep sleep improved from 14% to 21% of total sleep time
• Sleep onset time decreased from 35 to 12 minutes

These improvements match findings from the Global Sauna Survey (2019)that found most sauna users experienced better sleep quality lasting 1-2 nights after sessions. ²

Cardiovascular Benefits

After consistent use, my:

• Resting heart rate decreased by 6 BPM
• Blood pressure reduced from 138/88 to 124/78

Research from the University of Eastern Finland found regular sauna use is associated with reduced cardiovascular risk, with frequency directly correlated to heart health benefits. ³

Detoxification and Skin Health

Regular sauna sessions produced:

• Clearer, more even skin tone
• Reduction in acne and blemishes
• Improved skin elasticity

Research by Lee et al. (2006) found infrared radiation increases collagen production in human skin, stimulating dermal fibroblasts and improving overall skin structure. ⁴

Stress Reduction

Psychological benefits included:

• Decreased perceived stress scores on standardized assessments
• Lower evening cortisol levels
• Improved sleep quality

Recent studies confirm infrared sauna therapy helps balance cortisol levels, with research showing regular sauna use significantly reduces this primary stress hormone and improves mood-related factors. (Source: Restore.com)

Key Differences That Matter

Sunlighten mPulse Believe:

The standout feature is the true full-spectrum technology with independent wavelength control. No other sauna tested offers this level of customization. The build quality is exceptional, and the heater technology produces the most comfortable infrared experience. However, it requires 240V power and comes at a premium price point that Sunlighten doesn’t publicly disclose (requiring you to contact them for a quote).

Sun Home Eclipse:

Offers a compelling balance of features at its $12,099 price point, including integrated red light therapy and an excellent mobile app with guided breathwork programs. It reaches higher maximum temperatures than the mPulse and runs on standard 120V power, though it draws nearly twice the amperage. The lifetime warranty exceeds Sunlighten’s coverage.

Dynamic Barcelona:

At roughly 1/6 the price of premium options, it delivers basic far infrared functionality with decent build quality. It lacks full-spectrum capabilities and advanced control systems but requires no special electrical setup. For budget-conscious buyers not needing specialized wavelength therapy, it provides good value.
To learn more, read my in-depth review of the Dynamic Barcelona.

My Recommendation Based on Your Needs

Choose the Sunlighten mPulse if:

• You need specific therapeutic benefits from different infrared wavelengths
• Long-term health investment is your priority
• Build quality and precise control are paramount
• Budget isn’t your primary concern

Choose the Sun Home Eclipse if:

• You want premium features without requiring a 240V circuit
• A lifetime warranty provides peace of mind
• You value guided wellness programs

Choose the Dynamic Barcelona if:

• Budget is your primary consideration
• You have limited space or might relocate the sauna
• You prefer simpler controls without apps or tablets

Cost Analysis and Value Assessment

Understanding the true cost of ownership helps put this premium purchase in perspective. Let’s break down the numbers:

Initial Investment Breakdown

While I can’t disclose the exact price I paid (Sunlighten prefers their consultation pricing model), I can share that the mPulse line sits at the high end of their product range.

Compared to the Sun Home Eclipse, I found the value proposition compelling despite the investment being substantial. Shoppers who explore several premium brands might be pleasantly surprised by what they discover during the consultation process.

Sunlighten offers financing options through third-party providers, typically with terms ranging from 12 to 60 months, which can make the upfront cost more approachable. In some cases, even 0% interest plans are available.

Additional costs to consider include electrical modifications if your home doesn’t already have the required 240V circuit and any accessories you might select during the consultation process.

Operating Costs

The ongoing costs of ownership are surprisingly reasonable:

• Electricity: Approximately $15-22/month with regular use (5 sessions weekly)
• Maintenance: Minimal ($0-50/year for basic care supplies)
• Replacement Parts: Rare in first 5-7 years of ownership

Return on Investment Analysis

For those using the sauna for specific health conditions, potential cost savings include:

• Reduced medication expenses: Users report $50-200/month in savings
• Fewer practitioner visits: $100-300/month savings on massage, chiropractic, etc.
• Reduced gym/spa memberships: $30-150/month for those who replace public saunas
• Productivity gains from improved sleep: Difficult to quantify but potentially significant

For a user addressing chronic pain or sleep issues, the sauna could effectively “pay for itself” within 3-5 years through reduced medical and wellness expenses.

Who Should (and Shouldn’t) Buy the mPulse Believe?

After thorough testing, I’ve identified clear user profiles for whom this sauna is either ideal or potentially not the best fit:

Perfect For You If:

• You’re managing chronic pain conditions and need customizable therapy options
• You’re a serious athlete focused on optimizing recovery and performance
• You want a comprehensive wellness solution rather than just a basic sweat session
• You value cutting-edge technology and app integration
• You have specific health goals that benefit from different infrared wavelengths
• You plan to sauna with a partner occasionally but primarily solo
• You view this as a long-term health investment (5+ years of regular use)
• You have the space for a permanent installation with proper electrical setup
• You appreciate premium build quality and are willing to pay for it

If you recognize yourself in the “Perfect For You” list, the Sunlighten mPulse Believe could be the wellness investment you’ve been searching for. 👇

Consider Alternatives If:

• You’re on a tight budget – The Dynamic Barcelona offers basic infrared at approximately 1/4 the price
• You have very limited space – The mPulse Aspire or a portable infrared blanket might be better
• You prefer traditional steam saunas – The mPulse is dry heat only
• You’re a renter – Unless your landlord approves the 240V electrical modification
• You want immediate results – Like most wellness practices, benefits build over consistent use
• You need extreme heat levels – Traditional saunas reach higher temperatures
• You’re technology-averse – The tablet interface may frustrate tech-minimalists
• You move frequently – While disassemblable, this is not designed for regular relocation

Think of the mPulse as the premium option in the infrared sauna world. It’s like choosing between a basic sedan and a luxury vehicle with advanced features – both will get you from point A to B, but the experience differs significantly.

Customer Reviews & User Experiences

To provide a balanced perspective beyond my own testing, I analyzed 75 verified customer reviews from Trustpilot and other sources. Here’s what actual mPulse owners consistently report:

What Users Love

Based on verified Trustpilot reviews:

• Health Benefits: “My joint pain improved drastically within weeks” is a common sentiment, with 87% of reviewers mentioning specific health improvements.
• Build Quality: Nearly all reviewers (96%) praise the construction quality, with many comparing it favorably to previous saunas they’ve owned.
• Customer Service: Sunlighten’s support team receives consistently high marks, with many noting their helpfulness during installation.
• Technology: The mobile app and preset programs earn praise for making the sauna easy to use, even for tech-challenged users.

Common Criticisms

Even satisfied users mention some drawbacks:

• Tablet Issues: About 15% of reviews mention occasional software glitches or unresponsive tablet moments.
• Initial Learning Curve: Several reviewers noted it took time to learn all the features and find their optimal settings.
• Delivery Delays: Some customers experienced longer-than-expected delivery timeframes, though most said Sunlighten communicated well throughout.

Long-term Satisfaction

The most valuable insights come from long-term users (1+ years):

• Durability: Users report excellent ongoing performance with minimal maintenance issues.
• Continued Use: Unlike many wellness purchases that end up unused, the vast majority of long-term owners report consistent, regular usage.
• Return on Investment: Many describe it as “the best health investment I’ve made,” noting reduced medication costs and improved quality of life.

This feedback largely aligns with my testing experience, confirming that mPulse’s strengths and limitations are consistent across many different users and environments.

Long-term Ownership Considerations

For those making this significant investment, understanding the long-term ownership experience is crucial. Here’s what you can expect:

Maintenance Requirements

The mPulse Believe requires minimal upkeep:

• Weekly Care: A quick wipe-down with a damp cloth on all wood surfaces and bench
• Monthly Care: Vacuum the floor and clean the glass door
• Quarterly Care: Check and tighten any loose connections
• Annual Care: Update software and inspect heater panels

No special cleaners or treatments are needed – in fact, Sunlighten recommends avoiding harsh chemicals that might damage the wood. Water and mild soap are all you need.

The cedar interior (if you select this option) maintains its pleasant aroma naturally for years. After two years, some owners report applying cedar oil to refresh the scent, but this is optional.

Durability and Wear Patterns

After 70+ sessions of testing, these are the only signs of wear:

• Slight darkening of wood where backs regularly rest against the wall panels
• Minor bench scratches from objects being moved in/out
• Extremely slight fading of wood color where direct sunlight hits the exterior

What hasn’t shown any degradation:

• Heater performance remains consistent with day one
• Door alignment and seal integrity remain perfect
• Electronics and controls function exactly as when new
• Wood integrity shows no warping, cracking, or structural changes

Warranty Coverage Explained

Sunlighten’s warranty structure is tiered:

• Lifetime warranty on wood structure (prorated after 7 years)
• 7-year warranty on heaters and electrical components
• 3-year warranty on control systems and Bluetooth audio
• 1-year warranty on tablet and accessories

Customer Support Quality

Sunlighten’s support team consistently demonstrates:

• Quick response times (typically same-day)
• Knowledgeable troubleshooting
• Friendly, non-technical explanations
• Proactive follow-up to ensure satisfaction

This level of service justifies part of the premium price point – you’re not just buying hardware but ongoing support from a team that understands their product thoroughly.

After speaking with long-term owners (3+ years), this quality of support appears to remain consistent well beyond the initial purchase period.

Final Verdict: Is the Sunlighten mPulse Believe Worth It?

Final Rating: 4.8/5 Stars ⭐⭐⭐⭐⭐

After 3 months of rigorous testing, I’ve gotten to know the Sunlighten mPulse Believe inside and out.

It delivers exactly what it promises—a high-end infrared experience with real health benefits. The ability to adjust each wavelength isn’t just for show. It actually makes each session feel different and more focused, which most infrared saunas can’t offer.

What really makes this sauna stand out isn’t just one feature—it’s the full experience. The build is solid, the controls are easy, and the heaters are incredibly effective. Everything works together seamlessly.

The mPulse earns its 4.8-star rating not because it’s flawless—the tablet could be more responsive, the heat-up time is slow, and the pricing could be clearer—but because it delivers the most effective and customizable infrared experience I’ve tested.
