Water cooler bottles are commonly made from polyethylene terephthalate (PET) plastic.
While PET is widely used for its affordability and recyclability, it's important to note some concerns regarding its use in water bottles.
Here's a breakdown:
- PET Plastic: This is the most frequent material for the large, blue, reusable water cooler bottles.
- Potential Concerns: Some studies suggest that PET bottles can leach chemicals like BPA or DEHA into the water, especially when exposed to heat or prolonged storage. DEHA is a suspected carcinogen. The leaching of these chemicals is a valid concern regarding potential health risks.
- Alternatives: Other materials used for water bottles include:
- Polycarbonate: Although more durable than PET, polycarbonate contains BPA and is becoming less common.
- Stainless Steel: This is a reusable and safer alternative, as it does not leach chemicals.
- Glass: A highly inert and safe material, though heavier and more fragile.
Therefore, while PET is the standard material for water cooler bottles, it's advisable to be aware of potential chemical leaching. Choosing water stored in alternative materials, such as stainless steel or glass, can mitigate those risks.
