MiHIGH vs Reviiv Sauna Blanket: Which Is Better?

Q: Is there any reason to choose Reviiv over MiHIGH at the same price?

At equal prices, no — MiHIGH wins or ties on every dimension compared here, including the decisive independently verified EMF data. Reviiv only becomes a reasonable choice if you find it discounted significantly below MiHIGH's $349, in which case its lower price may offset its weaker documentation.

Q: How much does the 9°F heat difference between MiHIGH (167°F) and Reviiv (158°F) actually matter?

For most users operating in the typical 130–155°F range, the difference is marginal — both blankets comfortably cover that range. The gap matters more for users who specifically want to reach the highest available temperatures, where MiHIGH's extra headroom is the better option.

Q: What does MiHIGH's <3mG EMF rating actually mean in practice?

EMF Analytics, an independent testing laboratory, measured the MiHIGH at less than 3 milligauss (mG) during operation at body-contact distance — within or below typical residential background EMF levels (0.5–2mG). Reviiv has not published an equivalent independent measurement, so there's no comparable third-party figure to weigh against MiHIGH's.

Q: Are either of these blankets going to give me traditional sauna health benefits?

Treat such claims with scepticism for both. The cardiovascular research most often cited (Laukkanen et al. 2018) studied traditional Finnish saunas at 80–100°C of convective heat. Both the MiHIGH and Reviiv use far infrared radiation at lower surface temperatures (158–167°F, roughly 70–75°C) and have not been studied in equivalent cohorts.

Q: Should I consider a more premium blanket instead of either of these?

If independently verified EMF data combined with a higher temperature ceiling and 120-day return policy matters more than price, the HigherDOSE at $699 (ETL certified) is worth considering. For most buyers at the ~$349 price point, though, MiHIGH already provides the strongest available combination of verified safety data and value.

Build & Materials

MiHIGH Infrared Sauna Blanket 4/5

Reviiv Far Infrared Sauna Blanket 4/5

Verdict: Tie

Both use standard mid-range construction — PU or similar exterior with an appropriate inner lining. MiHIGH's PU leather specifically avoids the phthalate plasticizers associated with PVC, a sensible material choice. Reviiv's construction is comparable in quality but without the same explicit material reasoning published. Both are adequate, solid builds for the price tier.

Heat Performance

MiHIGH Infrared Sauna Blanket 4/5

Reviiv Far Infrared Sauna Blanket 3/5

Verdict: MiHIGH Infrared Sauna Blanket

MiHIGH reaches 167°F versus Reviiv's 158°F — a 9°F gap at the same price point. Both are adequate for effective heat therapy sessions in the typical 130–155°F operating range, but MiHIGH's higher ceiling gives it more headroom for users who want more intense sessions.

EMF & Safety

MiHIGH Infrared Sauna Blanket 5/5

Reviiv Far Infrared Sauna Blanket 3/5

Verdict: MiHIGH Infrared Sauna Blanket

This is the decisive gap. MiHIGH has independently tested EMF results at <3mG from EMF Analytics — a third-party laboratory measurement, not a brand claim. Reviiv makes low-EMF claims without publishing equivalent independent verification. At identical prices, MiHIGH's verified data is a meaningful safety-documentation advantage that Reviiv simply doesn't match.

Comfort & Usability

MiHIGH Infrared Sauna Blanket 4/5

Reviiv Far Infrared Sauna Blanket 4/5

Verdict: Tie

Both use the standard lying-down, full-body format with comparable inner linings and session experience. Neither brings a distinctive comfort feature, and both are adequate for the typical 30–45 minute session.

Portability & Storage

MiHIGH Infrared Sauna Blanket 5/5

Reviiv Far Infrared Sauna Blanket 4/5

Verdict: MiHIGH Infrared Sauna Blanket

MiHIGH folds to approximately 8 lbs, slightly lighter and more compact than Reviiv's comparable but marginally bulkier storage footprint. Both fold into a carry bag for home storage, but MiHIGH has a small edge in day-to-day convenience.

Value for Money

MiHIGH Infrared Sauna Blanket 5/5

Reviiv Far Infrared Sauna Blanket 3/5

Verdict: MiHIGH Infrared Sauna Blanket

At identical prices, MiHIGH delivers a higher temperature ceiling, independently verified EMF data, and better portability — there is no dimension where Reviiv pulls ahead. MiHIGH represents the strongest value case of any blanket reviewed in this category; Reviiv at the same price is comparatively weak.

Same Price, Different Documentation

The MiHIGH and Reviiv Far Infrared Sauna Blankets both retail at approximately $349, putting them in direct competition for the same budget. On paper, both are mid-range blankets with standard construction, comparable comfort, and similar form factors. The difference that actually matters is what each brand can prove about its safety claims.

The Decisive Factor: Independent EMF Verification

MiHIGH’s <3mG EMF rating comes from EMF Analytics, an independent testing laboratory — a third party measured the blanket and published the result. Reviiv claims low-EMF construction but does not publish an equivalent independent measurement. At different prices, this might be a minor consideration weighed against other factors. At identical prices, it’s difficult to justify choosing the unverified option.

MiHIGH also edges ahead on heat ceiling (167°F vs 158°F) and portability, while tying on build and comfort — there’s no dimension where Reviiv pulls ahead at this price.

Which Should You Choose?

Choose MiHIGH — at the same price, it wins or ties on every dimension, including the independently verified EMF data that Reviiv lacks.

Choose Reviiv only if you’ve found it meaningfully discounted below MiHIGH’s $349 price, where its lower cost may offset its weaker documentation.

Overall Verdict

At the same approximately $349 price, this isn't a close call. MiHIGH wins on heat performance, EMF documentation, portability, and value, and ties on the rest — it doesn't lose on a single dimension. The independently verified <3mG EMF rating from EMF Analytics is the standout difference: it's the kind of third-party safety data that Reviiv simply doesn't provide at the same price. Reviiv is not a bad blanket, but at equal pricing there is no reason to choose it over MiHIGH. Reviiv only becomes worth considering if found meaningfully discounted below MiHIGH's price.
