HigherDOSE Infrared Sauna Blanket
Reader ratings
A zip-up infrared blanket from a brand with an ETL listing for models OWV4 and OWV4_XL and no recall. The page claims detox and EMF benefits we do not back and does not name the model or the inner material. We are asking about both.
Best for People who want a low-cost way to try infrared heat at home and accept that it is a lying-down, lower-evidence alternative to a sauna.

How we evaluated it
Why we chose it What put it on our list
- A safety listing exists for the brand’s blanket. Intertek’s ETL directory lists HigherDOSE LLC infrared sauna blankets, models OWV4 and OWV4_XL, to UL 964 for electrically heated bedding (and CSA C22.2 No. 101 for Canada). The product page names no model, so we are asking HigherDOSE which one this is.
- Other brands’ blankets have been recalled for overheating: Lifepro Bioremedy (about 78,000 units, 32 burn injuries, October 2025) and Tzumi SLF (about 3,600 units, May 2026). A CPSC search on 2026-10-22 found no recall naming HigherDOSE.
- It states a heat range and power: up to 175 °F (about 79 °C) on a 1 to 9 level display, 350 to 420 W, with a 1-hour timer. The maker names its main material as waterproof polyurethane.
- One-year limited warranty, and the site banner advertises a 120-day money-back guarantee (check the terms).
Trade-offs What to weigh before you buy
- The page says the blanket will “accelerate detoxification” and “trigger all the same processes as a hard workout”, and lists “Deep detox + calorie burn”. Those are the maker’s words. Our detox page says metals show up in sweat, but no trial shows a lower body burden. The category guide lists detox claims as a red flag.
- EMF claims are unsupported. The maker says “Low EMF” and that a charcoal layer mitigates EMF and ELF, with no measurement. See our page on EMF-blocking products. The page also describes a “magnetic strip to ground the body” and a crystal layer that makes negative ions, with no evidence given.
- Two basics are unstated. The listed models are OWV4 and OWV4_XL, and the page does not say whether the current blanket is one of them. The maker says the blanket is “non-toxic, waterproof polyurethane that exceeds VOC safety standards” without naming the standard, and does not say what the body-side layer is or whether PVC is absent.
- A blanket warms you while you lie down, mostly at the skin. It has no long-term outcome research like the Finnish sauna studies (see our infrared vs traditional page). Two other brands’ blankets were recalled for overheating, so follow the manual.
What to know Details worth knowing first
A sauna blanket is a heated, zip-up wrap you lie in, sold as a low-cost stand-in for an infrared cabin. Intertek, an outside tester, lists a HigherDOSE infrared sauna blanket to the heated-bedding standard, UL 964, under model numbers OWV4 and OWV4_XL. That matters because two other brands’ sauna blankets, including a 78,000-unit Lifepro recall, were recalled in the past year for overheating. HigherDOSE’s page does not name its model, so we cannot yet say the listing covers the blanket on sale.
The other caveats are about claims. The page promises detox benefits and EMF reduction from a charcoal layer, and it gives no test for either. Our detox page is cautious about what sweating does, and our EMF-blocking page finds no support for shielding layers. The page also does not say what the body-side layer is made of, or whether PVC is used.
We are asking HigherDOSE for the model number that matches its listing, the inner-layer material and the measurements behind “Low EMF”, as the notice above says. If you try a blanket, follow the manual and ask a doctor first if you have a heart condition or are pregnant. For the evidence on infrared, see infrared vs traditional.
Quality & testing How it measures up against our checklist
| What we checked | What we found |
|---|---|
| Heat that matches the research Maker’s claim | Up to 175 °F (about 79 °C), per the maker, measured as the blanket’s setting rather than as air in a room. The Finnish studies used hot air at about 80 °C in a room. We have no independent temperature test. |
| Safety certification Not verified | Intertek’s ETL directory lists HigherDOSE LLC, trade name HIGHERDOSE, “Infrared Sauna Blanket”, models OWV4 and OWV4_XL, under UL 964 (ETL Listed) and CSA C22.2 No. 101 (cETL Listed). The product page names no model, so we could not confirm that this blanket is one of them. |
| Materials that hold up to heat Not verified | The FAQ says the blanket is “crafted from non-toxic, waterproof polyurethane that exceeds VOC safety standards”, with layers of heating elements, charcoal, clay, magnets and crystals. The standard is not named, the inner body-side layer is not described and PVC is not mentioned. Not verified. |
| Electric and magnetic field claims Not verified | “Low EMF”, and a charcoal layer to “mitigate EMF and ELF”. No measurement, distance or lab is given. Not verified. |
| Marketing claims Maker’s claim | The page makes detox and calorie-burn claims (“accelerate detoxification”, “Deep detox + calorie burn”) and quotes a survey of 1,044 users for relaxation results. |
| Recalls Verified | A search of the US Consumer Product Safety Commission recall database on 2026-10-22 found no recall naming HigherDOSE. It did find recalls of Lifepro and Tzumi sauna blankets. |
What the labels mean
- Verified We opened an independent record that confirms it: a certifier’s listing, a regulator’s list or a lab report. It is linked under Sources.
- Maker’s claim The maker says so on its own page or label. We read it but found no independent record.
- Not verified We looked and could not confirm it, or the maker does not say. Treat it as unknown.

Alternatives Other options to compare
- An infrared cabin with a model-matched ETL listing About $1,974 and larger than a blanket. Comes with a plain safety listing but no EMF figure.
- A wood-fired portable sauna tent Reaches traditional sauna heat (the maker says 200 °F and up), from about $1,500, but needs a fire and has its own safety questions.
- Cheaper blankets from Amazon or big-box stores Lifepro and Tzumi blankets sold at $130 to $199 have been recalled. Check cpsc.gov before buying any blanket.
