Houfu Cotton Tea Filter Bags for Loose Leaf Tea

Yes, these are genuinely 100% cotton with no plastic, synthetic fibers, or chemical coatings. They're unbleached and don't have those potentially toxic drawstrings you'll find on some other tea bags. Multiple users specifically chose these because they wanted to avoid microplastics in their tea, and they're happy with the authenticity of the cotton material.

They use a simple fold-over envelope design—you fill the bag, then fold the top over to seal it. It's actually easier than fiddling with a drawstring, and reviewers say it works surprisingly well at keeping the tea contained. The bags are durable enough that they won't tear or leak when you fold them, even with vigorous steeping.

The filtration is excellent—the cotton weave is tight enough to contain even fine tea particles while still allowing water to flow through for proper steeping. Several reviewers specifically mention that nothing leaks out, and the fold-over closure keeps everything secure. Just be aware that the opening is a bit small, so fill carefully to avoid spilling tea before you fold it closed.

They're on the smaller side at 3.7 x 2.8 inches, which is perfect for a single cup or mug. If you like a really strong brew or use bulky tea leaves, you might find them a bit limiting. But for standard loose leaf portions, they work well—just don't overfill them. The compact size actually helps them sink in your cup rather than float on top.

Yes, since they're 100% unbleached cotton with no synthetic materials, they'll break down in compost. Multiple eco-conscious reviewers specifically chose these for their biodegradability. They're also made in Japan, which some users appreciate for quality and manufacturing standards. You're getting 120 bags total (4 sets of 30), so the value is solid if you're looking to reduce waste from commercial tea bags.

These are actually great for beginners. The fold-over design is dead simple—no complicated closures or equipment needed. You fill, fold, steep, and toss. Several reviewers mention they're easy to use right out of the package. The forgiving construction means you don't have to worry about them falling apart, and since they're disposable, there's no learning curve for cleaning reusable infusers.
