I Took the Last Plastic Out of My Coffee. Here’s What I Bought.
Almost a year ago I threw out my Keurig.
The reason was simple once I looked at it. A K-Cup is a little plastic cup, and the machine forces water at around 190°F through it under pressure for twenty or thirty seconds. Heat, pressure and direct contact, every single morning. Most K-Cups are polypropylene, and a 2022 comparison found a single plastic-bodied pod can release tens of thousands of microplastic particles per brew. Separate work out of the University of Connecticut found pod systems can leach chemicals including BPA and benzophenone into the cup.
I drink four cups a day. That is not an occasional exposure, it is a daily habit.
So I switched to a drip brewer and felt good about myself for about eleven months.
Then I actually looked at the thing. The reservoir was plastic. The tubing the hot water ran through was plastic. The lid over the basket was plastic. I had removed the pod and kept the problem — just quieter, and out of sight inside the machine instead of sitting in my hand.
So that one is gone too. My coffee setup is now glass, stainless steel and wood. Nothing plastic touches the water at any point in the process.
Here is what I bought, what the research actually says, and an honest answer to the question everybody asks: is it more work?
Why Hot Water and Plastic Is the Worst Combination
Plastic sheds particles. That is not controversial. What matters is heat, pressure and contact time — and a coffee maker is the one appliance in the kitchen that combines all three, for years.
Researchers have been measuring it. A study of plastic drip bags found that a single bag steeped at 95°C for five minutes released more than ten thousand microplastic particles into one cup. The authors calculated that three to four cups a day would put roughly fifty thousand particles into you daily.
Where It Ends Up
The reason I care is what happens next. In March 2024 the New England Journal of Medicine published a study of patients who had plaque removed from their carotid arteries. The ones whose plaque contained microplastics and nanoplastics had a substantially higher risk of heart attack, stroke or death over the follow-up period than the ones whose plaque was clean.
That is an observational finding, not proof that the plastic caused it. Something else about those patients could explain it. But work since then has kept pointing the same direction — higher plastic concentrations in diseased arteries than healthy ones, and plastic turning up in brain tissue.
I am 71 and trying to reach 200. I cannot control the plastic in the rain or the soil. I can control what my hot water runs through at six in the morning.
What I Bought
Four things, about $115 all in.
1. Chemex Pour Over Glass Coffeemaker
About $49
One piece of borosilicate glass with a wood collar and a leather tie. No plastic anywhere on it, nothing to wear out, no electronics to fail. It has been made essentially the same way since 1941.
2. Stainless Steel Pour Over Filter
About $33
Double-layer mesh, wide metal base, fits the Chemex. No paper to buy and nothing to throw away. Read the next section before you buy this one — there is a real trade-off.
3. Bamboo Lid for the Chemex
About $13
Glass loses heat fast. A wooden lid on top keeps the carafe warm for the second, third and fourth cup. Small thing, but it is the difference between a setup you keep using and one you abandon in a month.
4. Electric Warmer
About $20
This one is not about plastic at all. It solves the actual reason people go back to a Keurig: pour-over coffee goes cold in the cup while you are reading. Three temperature settings and a four-hour auto shut-off. My coffee stays hot as long as I want it to.
Why I Use a Metal Filter and Keep the Oils
This part is a deliberate choice, and it is worth explaining because it goes against the standard advice.
A paper filter traps the coffee oils. A metal mesh lets them through. I want them through.
Those oils carry two compounds called cafestol and kahweol, and the laboratory work on them is genuinely interesting — antioxidant activity, anti-inflammatory activity, and some encouraging anticancer signals in cell and animal studies. Paper filtering throws all of that in the bin every morning. I would rather keep it.
Now the other side, because you deserve it. Cafestol also reduces how much LDL your liver clears from your blood, so unfiltered coffee raises LDL cholesterol. That effect is measured in humans, repeatedly, and it scales with how much you drink. A Norwegian study that followed around 500,000 people for two decades found filtered coffee associated with lower mortality than unfiltered. The benefits are mostly cell and animal work; the LDL effect is human work. That is a fair thing to weigh.
Eight Months of Unfiltered Coffee: My Actual Numbers
Here is the part I like about doing this in public. I do not have to argue about it — I already ran the experiment.
My previous machine used a metal filter too, and I drank four cups a day through it for about eight months. I have bloodwork from both ends of that window. Straight from my test and stats page:
- LDL cholesterol: 82 → 89 mg/dL (target under 100)
- Total cholesterol: 135 → 147 mg/dL (target under 200)
- HDL: 40 → 45 mg/dL — up, which is the direction you want
- Triglycerides: 47 → 44 mg/dL — excellent and holding
- ApoB: 69 mg/dL (target under 90)
Every one of those is in range, and ApoB — which many cardiologists now consider the most predictive single number on the panel — came in comfortably under target at 69.
Eight months of full-oil coffee did not wreck my lipids. It nudged LDL up seven points inside a healthy range while HDL improved and triglycerides stayed excellent. If the oils were doing real damage at four cups a day, eight months is long enough that I would expect to see it.
What I Am Watching in January
One set of markers I want a second look at. My advanced lipid panel showed LDL particle number and small-dense LDL running above the reference range, with a pattern B reading. Those happen to be exactly the markers unfiltered coffee is supposed to influence, and I only have one reading of them — so I cannot tell you yet whether coffee moved them, whether they were always there, or whether they are drifting down.
So my January panel is going to repeat the full subfraction workup, not just the basic lipids. Then I will have a real before-and-after on the exact numbers this argument turns on, and I will publish whatever comes back.
That is the honest version: I keep the oils on purpose, my basic lipids say that is working fine, and I have one more set of numbers to check in January before I would call it settled. If your own LDL is high, talk to your doctor before copying me — paper filters in the same Chemex are just as plastic-free and would cut the cafestol by more than 90 percent.
Is It Actually More Work?
Yes. And less than you think.
A Keurig is about thirty seconds of your attention. The Chemex is about four minutes. The routine: boil water in a kettle, put the filter in, add the coffee grounds, pour a little water to wet them, wait thirty seconds, then pour the rest in a slow circle. Walk away.
The first week it felt like a chore because I was thinking about it. By the second week it was just what I do while the rest of the morning gets going. It has become one of the few parts of my day where I stand still and do one thing, which at 71 I have decided is not a cost at all.
The other honest difference is cleanup. You rinse a metal filter and a glass carafe instead of tossing a pod in the trash. Thirty seconds at the sink.
What This Actually Buys You
I want to be careful here, because this is the part where most people overpromise.
Nobody has run a trial where they took plastic out of one group’s coffee routine and measured whether they lived longer. That study does not exist. What exists is: plastic sheds into hot liquid, plastic accumulates in human tissue, and people with more plastic in their arteries have worse cardiovascular outcomes.
That chain has a gap in it and I am not going to pretend otherwise. But the fix costs about $115 once, adds three minutes to my morning, and makes better coffee. I do not need certainty to take a deal like that.
The Rest of the Plastic
Coffee was the obvious one because of the heat. The others I have dealt with: no plastic cutting boards, no reheating anything in plastic, glass storage containers, and a hard rule about never leaving a plastic water bottle in a hot car. I am not fanatical about it. I am just not paying to run hot water through plastic anymore.
If you want the full picture of what I actually drink every morning, I wrote up my four-cup coffee protocol — what goes in each cup and why.
The beans matter as much as the brewer. I drink Danger Coffee, which is tested for mold and mycotoxins and remineralized — because there is not much point taking the plastic out of the water if the grounds bring their own problems.
Video Coming
I am going to film this setup and walk through the whole morning routine start to finish, because it is a lot easier to show than to describe. I will drop the video in here when it is up.
If you want to see what else I am doing, my full daily regimen is in my protocols, the training side is under fitness, and every number I track is in test and stats.
