No — a properly made, certified electric kettle does not cause cancer. Modern kettles are built from food-grade, heat-resistant materials that meet strict international safety standards. When used correctly, they are completely safe for boiling water and daily use.
However, concerns about electric kettles and cancer usually come from misuse, low-quality manufacturing, or unsafe materials, especially when boiling water in cheap plastic models. Let’s separate the facts from the myths and see how Shenbao ensures product safety through advanced design and certified materials.
People worry about electric kettles causing cancer mainly because of:
Poor-quality plastics that may release chemicals like BPA or phthalates when heated.
Unregulated metal components that might leach small amounts of nickel, lead, or other heavy metals into water.
Repeated re-boiling or improper cleaning, which could lead to scale buildup or contamination.
These risks are associated only with non-certified, low-quality kettles that use cheap materials. Reputable brands like Shenbao follow international health and safety standards that eliminate these dangers.
| Material | Safety | Description |
|---|---|---|
| 304/316 Stainless Steel | ✅ Safe | Food-grade, corrosion-resistant, and non-reactive; used in Shenbao’s interiors. |
| Borosilicate Glass | ✅ Safe | Chemically inert, doesn’t release toxins even at high temperatures. |
| BPA-Free Plastic | ✅ Safe | Used for outer housing or handles; does not contact boiling water. |
| Silicone Seals (Food-Grade) | ✅ Safe | Prevents leakage without releasing harmful compounds. |
When boiling water in a stainless-steel or Glass Kettle, there is no leaching of harmful substances, and thus no cancer risk.
Older or cheaper plastic kettles sometimes contained bisphenol A (BPA) — a chemical used to harden plastics that can leach into liquids when exposed to heat. BPA has been linked to hormonal imbalance and other health concerns, though not directly to cancer in small amounts.
Modern electric kettles, including all Shenbao plastic components, are BPA-free, meaning they are made from polypropylene (PP) or other certified food-grade plastics safe for hot-water contact.
Another misconception is that metal kettles release dangerous metals into water.
In reality, high-grade stainless steel (like 304 or 316) is non-reactive and corrosion-resistant. It doesn’t leach harmful elements even at boiling temperatures.
Low-quality or uncoated metal kettles might rust over time, but reputable brands ensure the use of certified stainless-steel alloys to prevent this.
To be sold internationally, electric kettles must meet stringent safety certifications proving that their materials are non-toxic and durable under heat.
Shenbao kettles comply with:
CE / GS (Europe) — Electrical and material safety
CB (IEC System) — International conformity standard
LFGB (Germany) — Food contact safety
RoHS / REACH (EU) — Restriction of hazardous substances
These certifications guarantee that no harmful substances will migrate into water during use.
Even with a safe kettle, proper use and maintenance are important for long-term health:
| Tip | Why It Matters |
|---|---|
| Boil only water | Milk or soup can burn and leave residue that affects taste and safety. |
| Avoid re-boiling multiple times | Repeated boiling concentrates minerals but doesn’t create toxins. |
| Clean monthly with vinegar or lemon | Removes scale buildup that could trap impurities. |
| Never leave water sitting for days | Prevents bacterial growth and odor. |
| Check for certification labels before purchase | Ensures safety-tested materials. |
Following these practices guarantees that your kettle remains clean, efficient, and safe.
Shenbao designs electric kettles with health and safety as top priorities.
Full stainless-steel interior — No plastic parts touch the water.
Concealed heating plate — Prevents corrosion and residue buildup.
Automatic shut-off and boil-dry protection — Prevent overheating and contamination.
Double-wall insulation — Keeps the exterior cool while preserving internal purity.
Certified BPA-free and LFGB-approved materials — Guarantee water safety and taste quality.
These innovations make Shenbao kettles ideal for homes, hotels, and offices where daily boiling is part of life.
A high-quality electric kettle does not cause cancer. Health concerns arise only from cheap, uncertified models that use unsafe plastics or untested metals.
By choosing a stainless-steel or glass kettle from a certified manufacturer like Shenbao, you ensure your appliance is safe, hygienic, and toxin-free — giving you pure boiling water every time.
Healthy materials. Trusted safety. Everyday confidence — that’s Shenbao.
