Tea bags vs loose leaf tea
Do I need to give up tea bags?
The verdict
Loose leaf, and this is the clearest single swap on the site. One nylon or PET pyramid bag released about 11.6 billion microplastic and 3.1 billion nanoplastic particles into a single cup at 95°C. A steel infuser puts no polymer in the water at all.
Stainless steel mesh, glass or ceramic vessel
58% confidence
These carry different evidence grades. Pyramid mesh tea bag is grade A and Loose leaf tea with a stainless steel infuser is grade C. One component of our score is measured release, which only earns points where a laboratory has actually counted particles — so a product nobody has tested scores lower than an identical one that has been. Part of the gap you are looking at is a difference in how much anyone has looked. Why we do it this way →
Where they actually differ
| Pyramid mesh tea bag | Loose leaf tea with a stainless steel infuser | |
|---|---|---|
| Measured release | 11.6 billion micro + 3.1 billion nanoplastic particles per bag | No polymer in the system |
| Evidence grade | A — direct measurement | C — no mechanism to measure |
| What makes it worse | Boiling water, dunking, squeezing the bag | A silicone-rimmed infuser puts a small face back in |
| Middle option | Stapled or stringed paper bags avoid the heat seal | — |
Where this comparison stops being reliable
The 11.6 billion figure is a particle count, not a mass — the total weight of plastic is small. The study measured release into water and followed it no further, so the health consequence at that dose is not established by it or by anything else.
The full picture on each
Does Pyramid mesh tea bag have microplastics?
Yes, and by the largest measured margin of any single item in the food literature. One nylon or PET pyramid bag at 95°C released about 11.6 billion microplastic and 3.1 billion nanoplastic particles into a single cup.

Does Loose leaf tea with a stainless steel infuser have microplastics?
No meaningful source. Steel mesh in a glass or ceramic pot puts no polymer in the water at all, which makes this the clean answer in a category where the alternative holds the record for the largest measured single-item release.

Neither of these is what you own
A comparison is between two product types. The item in your cupboard has its own packaging, its own age and its own condition. Scan it and get the same five-component score for the actual object.
