The Therapy Stack
More Than a Single-Therapy Mat
A HealthyLine mat layers up to seven components into one surface — which is why it can replace several single-purpose devices, including a HigherDOSE mat, with one daily routine.
*HealthyLine PEMF intensity varies by model: 8 Gauss across the Jet line, with the Jet 7428 delivering 12 Gauss.

Common Questions
HealthyLine vs Grooni FAQ
Yes — overall, we would choose HealthyLine JET.
Both are genuinely capable multi-therapy mats. Grooni actually offers a wider frequency range and more preset programs, so this is not a one-sided comparison.
Where JET pulls ahead is PEMF strength, red-light coverage, warranty, trial period and price. JET reaches 8 Gauss compared with Grooni’s 3.5 Gauss, includes substantially more integrated photon lights, costs slightly less, and comes with a stronger long-term ownership package.
The biggest difference is where each mat puts its technical emphasis.
Grooni focuses heavily on PEMF frequency programming, manual control and 13 preset programs.
JET operates across 0.25–30 Hz, but reaches a substantially stronger 8-Gauss peak intensity compared with Grooni’s 3.5 Gauss. JET also integrates 132 photon lights compared with Grooni’s 36 red-light LEDs.
Both heat up to 158°F and combine PEMF with FIR, red light, gemstones and negative-ion functionality.
HealthyLine JET has significantly stronger published PEMF output.
JET Series PEMF Mat reaches 8 Gauss, while Grooni publishes a range of 0.5–3.5 Gauss.
That makes JET's peak PEMF output roughly 2.3× higher than Grooni’s published maximum.
Both offer an impressively complete multi-therapy stack.
Both combine:
- PEMF
- Far infrared heat
- Red light
- Gemstones/mineral layers
- Negative ions
But JET Series provides a stronger PEMF output and much denser integrated light coverage, while Grooni’s provides a wider frequency range and larger preset library.
Yes — both include red light, but JET provides significantly more integrated light points.
JET Series PEMF Mats provide 132 integrated photon lights, while Grooni uses 36 LEDs at 660nm.
JET offers the stronger overall value.
For less cost, JET provides:
- Up to 12 Gauss vs 3.5 Gauss
- 132 photon lights vs 36 LEDs
- FIR heat up to 158°F
- Multi-therapy gemstone construction
- Up to a 5-year warranty vs 2 years
- 90-day trial vs 60 days
Grooni gives you more frequency presets, but JET gives you more hardware performance and longer ownership protection for less money.
HealthyLine offers eligible mats with up to a 5-Year Limited Warranty and 90-day trial.
Grooni currently offers a 2-year warranty and 60-day money-back period.
HealthyLine also provides Lifetime Trade-In and Lifetime Upgrade programs for eligible products, extending the ownership value beyond the original warranty period.
Yes. HealthyLine accepts HSA/FSA funds for eligible heated products, including the JET Series.
Eligibility can vary by plan, so confirm your specific requirements before completing your purchase.
Grooni deserves credit for its wider frequency range and 13 presets. But JET costs less while providing more than twice the published peak PEMF strength, considerably more integrated photon lights, longer warranty coverage and a longer trial period.
When the complete package is considered, JET gives you more hardware and long-term value for the money.
