SUMAJU Empty Tea Bags - Disposable Drawstring Filter

Three things matter most: material quality, size, and closure. SUMAJU covers all three well. The material is unbleached and chemical-free, so it won't add off-flavors to your tea. They come in a 3.54 x 2.75 inch size that gives leaves room to expand — crucial for proper steeping. And the drawstring closure holds contents securely without the fussiness of heat-seal bags. Reviewers consistently highlight the sturdy construction and the fact that the bags don't tear or rip during steeping.

SUMAJU's 3.54 x 2.75 inch size works well for most standard single-cup brewing. It gives leaves enough room to expand, which is important for full-leaf teas like oolongs and white teas that unfurl significantly. For larger-volume brewing like cold brew coffee, reviewers use multiple bags rather than overstuffing one. If you're brewing CTC (cut-tear-curl) black teas or finely chopped herbals, you need less space, so this size is more than adequate.

Yes, and reviewers specifically call this out as a great use case. The recommended method from actual buyers: fill 4 bags with coffee grounds, place them in a 2-quart jar of cold water, and steep for 12 hours in the fridge. The bags hold the grounds securely and make cleanup effortless — just pull out the bags and toss them. No messy French press to scrub.

The unbleached, chemical-free material is specifically designed not to add off-flavors. Unlike bleached paper filters that can impart a subtle papery taste, unbleached bags are more neutral. Reviewers don't report any taste interference, and the material allows proper water flow so your tea steeps fully. If you're a purist about flavor, the unbleached material is actually a selling point.

They're actually one of the easiest entry points into loose leaf tea. Reviewers describe them as easy to fill and use, and the 3.54 x 2.75 inch size is forgiving — you don't need to measure precisely. The drawstring closure is straightforward compared to fold-over or heat-seal alternatives. At 300 bags per pack, the per-bag cost is low enough that you can experiment freely without worrying about waste. If you've been curious about loose leaf but intimidated by infusers and gaiwans, these are a great starting point.

Absolutely — reviewers use these for all sorts of things beyond tea. Popular non-tea uses include: cloves, ginger, and turmeric powder for herbal infusions; cold brew coffee (see above); packaging homemade tea blends as gifts; and steeping garden-grown herbs. A few people even use them for spice sachets in cooking. The sturdy construction handles heavier contents like coffee grounds without tearing.

The bags themselves are sturdy enough for repeated steeping — reviewers confirm the construction holds up. Whether you'd want to re-steep depends more on the tea inside. Most loose leaf teas (especially oolongs and pu-erhs) are great for 2-3 steeps. Just leave the bag sealed and steep again with fresh hot water. The drawstring stays secure through multiple uses.

Reusable options are more eco-friendly long-term, but they require cleaning after every use and can retain flavors between different teas. SUMAJU disposable bags trade sustainability for pure convenience — fill, steep, toss, no cleanup. They're also better for fine or powdery ingredients (turmeric, ground spices) that would permanently stain cloth bags. At about a penny per bag with 300 in a pack, the cost is minimal for the convenience you get.

That depends on your brewing habits, but reviewers note that 300 bags go quicker than you'd expect. If you drink 2-3 cups of tea a day, you're looking at roughly 3-4 months. If you're also using them for cold brew coffee or herbal infusions, that number drops further. One thing to note: the packaging is shrink wrap rather than a resealable box, so you'll want to transfer them to a container or zip-lock bag for tidy storage.

Yes — this is one of the unexpected uses reviewers highlight. You can fill the bags with your custom blend, pull the drawstring closed, and they look clean and presentable. The unbleached natural paper has a nice artisanal look that works well for homemade gifts. Just keep in mind the bags are functional, not decorative — you'd want to pair them with nice packaging or a tin for a polished gift presentation.

Reviewers mention occasional drawstring breakage, but describe it as rare. The quality of the drawstring closure is actually one of the more praised features — multiple reviewers highlight it positively. Just pull firmly but don't yank aggressively and you should be fine. With 300 bags in a pack, even if one in fifty has a weak drawstring, it's not a meaningful issue.

The microplastic concern primarily applies to heat-sealed nylon or plastic mesh tea bags — the kind that look silky or pyramid-shaped. Brands using those materials have been flagged in studies. SUMAJU bags are a different product entirely: they're unbleached paper filter bags you fill yourself with loose leaf tea. There's no plastic mesh or heat-sealed plastic involved, so microplastic leaching isn't a concern here.

Honestly, for most people these filter bags replace the need for a strainer entirely. Strainers are great if you want a reusable option, but they require cleaning and don't work as well for fine herbs or powdery ingredients. With 300 bags in a pack, you've got months of daily brewing covered. The one scenario where a strainer still wins: if you're brewing the same tea multiple times in a gaiwan or small teapot and want to do quick successive steeps.

The material is porous enough to let hot water flow freely through it — which is essential for proper steeping — but the weave is tight enough to trap tea leaves, herbs, and particles inside. SUMAJU's unbleached paper material specifically gets called out by reviewers for allowing good water flow while keeping contents contained. Think of it like a tiny, single-serve coffee filter shaped as a bag.

Simple: open the bag, spoon in your loose leaf tea (about 1-2 teaspoons for a standard cup), pull the drawstring to close it tightly, and drop it in your mug of hot water. Steep for your preferred time, then lift out and discard. Reviewers say they're easy to fill and forgiving for beginners. One tip from actual users: make sure you pull that drawstring snug — if it's too loose, you might get a few particles escaping.
