BEFORE YOU BUY
IS MICROCURRENT THERAPY SAFE?
Yes. Microcurrent therapy uses very low currents (microamperes — about 1,000× weaker than a TENS unit) that are comparable to your body's own nerve impulses. It has been used clinically for over 40 years. No serious adverse events have been reported in the clinical literature for microcurrent at therapeutic levels.
DO I NEED A PRESCRIPTION TO BUY KFH ENERGY OR NOVO?
That depends on where you live.
-
In the European Union, UK, and most of the world: No prescription required. You can order directly.
-
In the United States: Yes, a prescription is required under FDA regulations for this class of device. Please email your prescription to sales@kfhealth.eu — we'll confirm receipt and arrange shipping.
WHEN SHOULD I NOT USE KFHEALTH DEVICES?
Do not use KFH Energy or KFH Novo if you:
- Have a pacemaker or other implanted electronic medical device
- Are pregnant (consult your doctor first)
- Have active cancer (consult your oncologist before use — (read our guidance on cancer)
- Have open wounds or broken skin at the electrode placement site (for KFH Novo, electrodes should be placed around, not on, the wound)
Always consult a healthcare professional if you're uncertain whether microcurrent therapy is right for your condition.
CAN I USE IT WITH MY MEDICATION OR OTHER TREATMENTS?
Yes. KFHealth devices have no known interactions with medication and are designed to complement — not replace — existing treatments like medication, physiotherapy, and wound care. Keep following your healthcare provider's guidance.
WHAT WILL I FEEL DURING TREATMENT?
Most users feel nothing at all. Some report a slight tingling where the electrodes are placed. A small indicator light on the device confirms it's working even if you can't feel it.
IS IT REIMBURSED BY MY HEALTH INSURER?
In certain cases, provided your doctor or therapist has referred you, you may qualify for reimbursement.
USING YOUR DEVICE
WHAT ARE THE KNOW SIDE EFFECTS?
There are no known side effects. There are no reports of side effects, and that is consistent with what we know about M.E.T. Moreover, patients quickly learned how to apply the therapy daily, and there were no problems with the practical application of the device. It turns out to be a safe solution for so many people who are tormented by fatigue, pain and lack of stamina.
WHAT WILL I FEEL WHEN THIS DEVICE IS IN OPERATION?
Many individuals do not feel anything. Some feel a slight tingle at the adhesive electrode. An indicator light on the device signals if the device is functioning or not.
WHAT ARE THE PRECAUTIONS?
- Do not immerse the device in water or any other liquid.
- Never connect the appliance directly to the mains power supply.
- Keep out of reach of children.
If, for any reason, you feel uncomfortable during treatment, you can switch off the device by lightly pressing the on/off area with your finger. As an extra safety measure, the device automatically switches off at the end of the selected treatment time.
HOW SOON WILL I NOTICE RESULTS?
Results depend on your condition. With daily use, some users notice changes within 1-2 weeks; others take several weeks. For chronic conditions, we recommend 8-12 weeks of consistent use before evaluating results. KFHealth is a supportive therapy — results vary by individual.
HOW OFTEN AND HOW LONG SHOULD I USE IT?
Use for at least 60 minutes per session, 5 days a week. More is fine — there's no known upper limit, and daily use is ideal. For best results, be consistent.
WHAT TIME OF DAY IS BEST?
Morning is preferred, especially for KFH Energy, because users may experience increased alertness that can disrupt sleep if used late in the evening.
DO I NEED A REFERRAL FROM MY DOCTOR?
Outside the US, no referral or prescription is required. We do recommend informing your doctor or physiotherapist, especially if you're treating a chronic condition, so they can integrate it into your care plan.
CAN I TRAVEL WITH MY DEVICE?
Yes — KFHealth devices are safe for air travel and can pass through airport security without damage. If asked, a brief explanation that it's a medical device is sufficient. Car, train, and bus travel pose no issues.
ISN'T IT DANGEROUS TO TREAT YOURSELF WITH ELECTRICITY?
No, Microcurrent Electro Therapy (M.E.T.) is a very fine, barely perceptible electrical energy (millionth amperes), comparable to your body’s own nerve impulses.
CAN I JUST LEND SUCH A DEVICE TO SOMEONE ELSE OR IS IT DANGEROUS?
For general use (fatigue, pain and endurance) there is no danger. For other applications it is wise to first seek advice from one of our advisors.
WHAT KIND OF PAIN CAN/CAN'T I TREAT WITH KFH ENERGY?
In principle, any form of pain is eligible for treatment with KFH ENERGY if it is related to muscle and joint pain and chronic musculoskeletal and nerve disorders such as fibromyalgia and rheumatic disorders.
CAN I ALSO USE THIS THERAPY FOR MY CHILDREN?
You can treat your children from the age of 6 years.
HOW LONG SHOULD I CONTINUE TO TREAT?
In acute cases until the symptoms have disappeared. For chronic conditions it is still necessary to continue to treat regularly, depending on the condition.
DO I HAVE TO KEEP DOING THIS THE REST OF MY LIFE
Most patients do find that maintenance usage is required to maintain their improvement in stamina, fatigue, and pain. This is very much an individual situation; many patients use the device one to three days per week for maintenance. Some less and others more!.
HOW DO I KNOW THAT THE TREATMENT WORKS?
If your pain decreases, if you become more mobile, sleep better, get more energy, if you start to feel more positive and/or calmer. If you clearly notice one of these improvements or a combination of these, the therapy will strike.
DEVICE, BATTERIES & CONSUMABLES
4 × AA batteries, minimum 1700 mAh capacity. For longest runtime, we recommend rechargeable NiMH batteries of 2400-2800 mAh or premium alkaline/lithium AAs. (Avoid cheap zinc-carbon "heavy duty" batteries — they run out quickly.)
WHAT SHOULD I DO IF THE "EMPTY BATTERIES" LIGHT IS ON?
Then replace the batteries. This is easy to do yourself. For more information, refer to the user manual.
The KFHealth units works with standard AA batteries, preferably with alkaline or lithium batteries. You can find them everywhere in the market.
When buying, look at the capacity of the battery. This is expressed in mAh (milliampere hours). Make sure that the capacity is at least 1700 mAh, ideally batteries with a capacity of 2400 or 2800 mAh. These batteries are also called “heavy duty” batteries.
Of course you can also choose to buy rechargeable batteries. The same advice applies for the capacity (ideally 2400 or 2800 mAh). This is cheaper to use and saves our environment.
WHAT SHOULD I DO IF, FOR EXAMPLE, YOU LOSE ADHESIVE ELECTRODES?
You can at any moment order adhesives electro patches on our website.
HOW OFTEN SHOULD I REPLACE THE BATTERIES?
If the light is on, you should replace the batteries. Out of our lab testing we may conclude that new batteries will give you on average 30 hours of treatment time.
HOW CAN YOU KNOW WHEN TO REPLACE THE ADHESIVE ELECTRODES?
It is best to do this when:
- The adhesive electrodes no longer stick to the skin;
- The gloss of the adhesive gel of the electrodes is completely gone.
Do not treat yourself with electrodes that actually need to be replaced, the therapy looses its efficacy, which can negatively affect the results.
WHEN SHOULD I REPLACE THE ADHESIVE ELECTRODES?
When the electrodes no longer stick well to the skin. The transfer of current to the skin is then no longer optimal.
HOW COMPLICATED IS IT TO OPERATE A DEVICE?
Simply by pressing the on/off button and applying the electrodes to your skin.
CAN I TRY IT BEFORE I BUY SUCH A DEVICE?
You can make an appointment with a therapist/advisor to discuss the possibilities. Send us an email and we will refer you to an advisor in your area.
HOW LONG DO BATTERIES LAST?
Lab testing shows approximately 30 hours of treatment time from a fresh set. The low-battery indicator light will come on when it's time to replace them.
HOW OFTEN SHOULD I REPLACE THE ADHESIVE ELECTRODES?
Each pair gives at least 10 treatments — typically around 2 weeks with daily use. Replace sooner if:
- The adhesive gel has lost its shine
- The electrode no longer sticks firmly to the skin
- Treatment feels less effective than usual
Worn electrodes reduce current transfer and therapy effectiveness.
WHAT IS THE END OF LIFE OF THIS DEVICE?
Our lab testing has recorded 7,088+ active hours of use with fewer than 0.04% failures over 3 years. With normal care, your device should serve you reliably for years.
We performed long term testing in our lab where we tested several devices on reliability and its lifetime. A total of 7088 active hours have been recorded on several devices without any recorded failure. We have recorded less then 0,04 failures in 3 years of usage. We stopped testing our devices after they run for 1.000 hours.
