Hanging Ear Drip Coffee Filter Bags - 50 Pack
Quick answer: Ridgebrew Hanging Ear Drip Filter Bags are food-grade, oxygen-bleached paper filters that hold up to 10g of ground coffee and brew directly into any mug up to 90mm wide — no dripper required. Backpackers and minimalist campers who want zero-cleanup pour-over coffee without carrying extra hardware will find these the lightest disposable option at 2g per filter.

Why disposable ear-drip filters outperform reusable camp setups
Reusable camp drippers add 60–120g of hardware to your pack and require wet grounds to be packed out or buried — both friction points on a multi-day route. These filters are self-contained: the paper holds the grounds, the crimped ears span the mug rim, and the whole unit goes into a fire pit or trash bag when you're done. Outdoor coffee consumption rose 27% from 2020 to 2024 (Outdoor Foundation Participation Report), which means more campers are demanding a real brew method, not instant powder.
The oxygen-bleaching process removes chlorine compounds from the paper pulp, which eliminates the papery off-taste that unbleached filters can introduce. Each batch is hand-tested for seal integrity before shipping, so grounds stay in the filter rather than settling into your mug. The Specialty Coffee Association Brewing Standards recommend a 1:18 coffee-to-water ratio and a total brew time of 4–6 minutes — parameters these filters are sized to support with a standard 200ml pour at 195–205°F.

How to brew
- Grind your coffee to a medium-coarse consistency — roughly the texture of coarse sea salt. Add up to 10g per filter (a standard single-serve dose).
- Unfold the ear hooks and hang them over your mug rim. The double-fold crimp supports mugs up to 90mm wide; confirm the filter hangs centered before pouring.
- Heat water to 195–205°F (just off a rolling boil). Per Specialty Coffee Association Brewing Standards, this range extracts soluble compounds evenly without scorching the grounds.
- Bloom first: pour 20–30ml of water over the grounds and wait 30 seconds. This releases CO2 and improves extraction uniformity.
- Pour the remaining water in slow, steady circles — target 200ml total over 3–4 minutes. Remove the filter, fold the ears inward to contain the grounds, and dispose in a fire pit or pack it out per Leave No Trace Center pack-out guidelines.
Care & longevity
- Store unused filters in a dry location away from direct sunlight; moisture can weaken the paper seal and compromise the ear-hook crimp before use.
- The paper is food-grade and free of chlorine residues due to the oxygen-bleaching process. No food-contact chemical standards equivalent to NSF/ANSI 51 apply to single-use paper, but the material meets food-safe paper manufacturing requirements.
- Used filters containing grounds are compostable in most municipal systems; confirm local guidelines before composting in the field. For backcountry use, pack out spent filters in a sealed bag or burn completely in an established fire pit.
- Ridgebrew guarantees seal integrity on every filter in this pack. If any filter in your order arrives with a compromised seal or structural defect, contact Ridgebrew for a replacement — no return shipment required.
Frequently asked
- Q: Are these filters safe to use over an open campfire?
- The filters are not placed over a flame — they hang on the mug rim while you pour hot water through them. Water temperature up to 205°F is within the design range. Do not submerge the filter in boiling water or place it directly over a heat source.
- Q: What mug sizes are compatible?
- The ear hooks span rims up to 90mm wide. Most standard 12–16oz camp mugs, enamel cups, and wide-mouth tumblers fall within this range. Measure your mug's outer rim diameter before use if you are unsure.
- Q: How much coffee should I use per filter?
- Each filter holds up to 10g of ground coffee. For a 180–200ml brew, 10g aligns with the Specialty Coffee Association's recommended 1:18 ratio. Reduce to 8g for a lighter cup.
- Q: How do these compare to Kuju Pour Over Pocket bags?
- Kuju bags come pre-filled with ground coffee at roughly $2.50 per brew — useful if you are not carrying a grinder. Ridgebrew filters cost $0.20 each and let you use any coffee you choose, which matters on trips longer than a day or two.
- Q: Can I compost the used filters?
- Yes. The oxygen-bleached paper is compostable in most municipal systems. In the backcountry, follow Leave No Trace Center pack-out standards: seal spent filters in a waste bag or burn them completely in an established fire pit.
- Q: What is included in the 50-pack?
- The pack contains 50 individual hanging ear drip filter bags. Coffee is not included. Total pack weight is 100g. No additional hardware, dripper, or stand is needed.
