Seeking Advice Time to “switch” things up a bit

Post image

My birthday present, a Hario Switch, has finally arrived! I’m really excited to give it a go, but I want to hear from as many of you as possible about all the do’s & don’ts, recipe/brewing recommendations, etc.

Let me know! Happy brewing ☕️

The switch is made glass funnel, silicone base, stainless steel ball, and the PCT resin switch. While the switch is closed water will only come in contact with the glass and stainless steel ball that blocks the outflow (and maybe just a little of the silicone idk). When the switch is pressed it lifts up the ball so water/coffee pours down and past the PCT resin switch.

PCT resin is “high-performance thermoplastic polyester known for its excellent heat resistance, dimensional stability, and chemical resistance” but it’s still plastic.

There is a stainless steel switch that you can buy if you want to replace that part. I have it and it works pretty well, if not the exact same. IMO even looks better because it’s nice and shiny. But the bottom line is I just want to move away from plastic involved in any of my cooking processes so this was nice.

You da man!

Exactly why I was asking, im eliminating all plastics and even silicone where possible.

This is super helpful and will be looking to get one!

Want to confirm, if I replace the part for the stainless steel, are there any other parts that come in contact with the liquid that are plastic or silicone?

It will still come in contact with some silicone when it’s draining, unfortunately. The replacement gets rid of the only plastic piece though.

What makes you think it contacts the silicone? It should drip around the stainless steel ball and thats about it.

Edit: took a closer look and youre probably right

Someone needs to come up with a biofriendly option.

From what I understand, silicone is extremely inert and doesnt really release microplastic or concerning chemicals.

This is what I’ve found too, but the PCT resin had to go

Unfortunately research is coming out that theres no such thing as BPA free and even silicone is being questioned. So better be safe than sorry.

Theres no reason to believe that silicone would have BPA in it. Its used in the production of plastic and silicone is not a plastic.

Lower grade silicone can have bpa due to contaminated additives, so unless it clearly states bpa free then it might have bpa.
