Melitta #4 Cone Coffee Filters, Unbleached Natural Brown, 100 Count Review (2026)

What these filters are

These are Melitta's #4 size cone-shaped paper filters, sized to fit standard 8 to 12 cup drip coffee makers that use a cone-style filter basket, as well as most single-cup cone pour-over drippers of the same size. The natural brown color means the paper is unbleached rather than processed white, which some drinkers prefer for a slightly more neutral filter taste and a more visibly natural product. Each box holds 100 filters, a supply meant to last through months of regular brewing for a typical household rather than a quick top-up pack, making it a practical restock size for anyone who already owns a compatible cone-style brewer.

Material and certifications

The paper is unbleached and natural brown, built with what Melitta calls microfine flavor-enhancing perforations designed to improve filtration, along with a double-crimped seam meant to resist bursting during brewing. The filters carry several third-party certifications: FSC certification from the Forest Stewardship Council for responsibly sourced paper, BPI certification from the Biodegradable Products Institute confirming they are commercially compostable, Kosher certification, and labeling as gluten-free and chlorine-free. The box itself is made from recycled paperboard, extending the sustainability angle beyond the filters themselves and giving buyers who care about packaging waste a small additional reason to choose this option over a plain plastic-wrapped pack.

Brewing performance

As a standard paper filter, these are built for everyday reliability rather than any specialty brewing feature, and Melitta positions the unbleached brown option as functionally equivalent to its bleached white filters in terms of filtration and fit, with the difference coming down to paper color and processing rather than brew strength. Because they are a standard single-ply paper rather than a thicker premium filter, they can feel thinner in hand than some higher-end specialty filter brands, though this does not affect their described compatibility or certified burst resistance during a normal brew cycle. Most home coffee makers will not show a noticeable taste difference between the brown and white versions of the same filter line.

Compatibility to check before buying

The most important thing to confirm before ordering is filter shape. These are cone filters designed for cone-style filter baskets, and they will not fit flat-bottom basket coffee makers, which need a different, flat-bottomed filter shape entirely. Buyers should check their machine's manual or filter basket shape rather than going by cup count alone, since both cone and flat-bottom filters are sold in similar 8 to 12 cup sizing that can look interchangeable at a glance. Getting the shape wrong means the filter will not seat properly and can let grounds spill into the finished pot.

Value and how long a box lasts

At 100 filters per box, this pack is built for households that brew coffee daily rather than occasionally, and buying in this size generally offers a better per-filter cost than smaller boxes of the same product line. For a household brewing one pot a day, a single box can realistically last several months, making it a low-effort item to keep stocked in the pantry rather than something to reorder often. Because the filters are a commodity paper good rather than a specialty item, the main decision points remain size, shape, and whether unbleached brown or bleached white paper is preferred for a given kitchen.
