Basket infuser vs strainer vs fill-your-own filter bag
Three ways of keeping leaf out of the cup, and they differ on the one variable that decides how strong the tea gets: how much room the leaf has while it steeps. A confined leaf cannot circulate, and most of its surface never meets water.

What is being compared
Why these get confused
Filter bags are read as ‘teabags’ and dismissed for it. The bag was never the variable — cut leaf was — and a filter bag holds whatever leaf you put in it.
Point by point
| Aspect | Mug infuser basket | Tea strainer | Empty filter bag |
|---|---|---|---|
| Where the leaf steeps | Inside the basket, which is usually smaller than the wet leaf needs. | Free in the pot or mug. The strainer only acts on the way out. | Inside the bag, which should be filled no more than half full. |
| Room to expand | Depends entirely on basket size, and most are too small. | Unlimited. This is the whole argument for the method. | Limited, and the limit is easy to exceed because the bag looks empty. |
| Fine leaf and dust | Passes the mesh and settles in the mug. | Caught, which is what a strainer is for with broken leaf. | Caught completely — paper is the finest filter of the three. |
| Reusable | Yes, indefinitely. | Yes, indefinitely. | No. Single use. |
| What you wash | Fine mesh, immediately, or dried leaf blocks the flow. | Fine mesh, immediately, same problem. | Nothing. |
| Portability | Awkward — the wet basket needs somewhere to go. | Awkward for the same reason, plus a pot. | The strongest case for it: nothing to carry back. |
| Best use | Everyday desk brewing, provided the basket is large. | Any pot where the leaf brews loose, and gongfu, where the leaf must be free to move. | Travel, offices, and demonstrating that the bag was never the problem — the leaf grade inside it was. |
The short answer
If loose leaf has been tasting weak, the ranking here is straightforward: loose in the vessel with a strainer beats a large basket, which beats a small basket, which beats a half-stuffed filter bag. Nothing about that ordering depends on the tea.
