Question: Is there any plastic inside?
Document: Otherwise the only plastic inside is the lid and filter.
Works well, nice design. Like that you can adjust the temperature, and like that it is all metal inside versus many that are plastic.
This is a much better kettle than what I had expected. It has almost no plastic inside and a temperature control based on tea-type, from green to white to oolong to black. I am pleased with its performance, it heats quickly and so far, consistently.
I bought this as a gift fro my daughter. I have always loved Melita products, but she didn't appreciate the style. Hard to reach inside and hard to read the fill mark, she told me. She likes that it is stainless inside and not plastic. I don't know if she will keep it or not.
The water does not touch this plastic while it's heating up, only while pouring. The water level gauge (just under the handle) is also some sort of plastic, but the water inside the gauge is sort of separate from the water in the main chamber that's being heated. Kind of hard to explain, but the gauge is a separate little chamber and there are just little openings that allow the water into it. The little openings appear to be some kind of rubbery silicone material.
I bought this to use in my office and so far it's terrific. The water boils quickly and it's easy to store in a cupboard. When boiling less than the minimum amount of water (about 0.75 liter) the auto shutoff may not work correctly, but it heats the water so fast that I don't have time to wander off and get distracted. There are two small plastic grommets inside that allow the water into the fill level indicator under the handle.
We use our kettle every day and just don't know how to do without one. When our first one died after years of constant daily service I didn't hesitate to order exactly the same one again. The floor of the inside does discolor with time but it never affected the performance or taste of anything. We had plastic ones from a cheaper bargain store but took it back after the first use! This one is a workhorse. The only thing is I can't see why the dial setting.
Used it once, threw it out! Boiled water smells of heated plastic. The entire purpose to buy a stainless steel kettle is the avoidance of the toxic effects of heated plastic. There are two soft plastic nobs inside that will get in contact with boiling water at every use. The top of the kettle is held together by hard plastic and glue. Also there is a plastic filter inside. The heating plate is entirely made of plastic and looks cheap. The kettle has no holding feature.
I am very happy with this kettle, although I have only had it for a week, so its durability is yet to be tested.It is almost all metal inside, except for the lid, filter and parts of the water-level.
I suppose you'd have to contact the seller to find out, but it's probably safe to assume that if it doesn't say "BPA-free" that it's not. In any case, I think the only ones that are completely metal inside just have one temp (boil).The water heats up really quickly.
Answer: It's all metal inside except for two very small silicone "plugs" where the water level is measured on the outside of the unit. The lid is plastic. I love it!
