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

Who these filters fit

These Melitta #4 filters are sized for cone shaped, or conical, drip coffee makers in the 8 to 12 cup range, and Melitta also notes they work in most single cup pour over cone brewers that take a #4 sized paper. Anyone brewing on a Melitta cone system, or a compatible cone brewer from another brand that uses the same #4 sizing, is the target buyer here. Because this is the Premium line rather than Melitta's standard filter, it suits drinkers who already like Melitta's basic unbleached paper but want a noticeably cleaner cup and are willing to pay more for it. Owners of flat bottom drip machines, which use a different filter shape entirely, should double check their brewer's filter style before buying, since a cone filter will not sit correctly in a flat basket.

What makes this paper different

The Premium filters use what Melitta describes as microfine perforations paired with a double crimp seam, a combination designed to be more burst resistant during brewing while still letting water pass through evenly for extraction. That construction is also meant to trap more of the fine sediment and bitter oils that can otherwise pass into the cup with a thinner or lower grade filter, producing a cleaner tasting brew with less grit at the bottom of the pot. The paper itself is unbleached and left in its natural brown color rather than whitened with chlorine, which appeals to buyers who prefer to avoid bleaching chemicals in something that touches hot water daily. The filters are also certified biodegradable and compostable through both the Forest Stewardship Council and the Biodegradable Products Institute, and Melitta notes they are made in the USA.

Living with it

Day to day, a box of 100 lasts a regular single pot per day household roughly three months, which owners generally find keeps per cup filter cost reasonable despite the higher price than Melitta's standard line. Because the paper is thicker and the crimp sturdier, filters are less likely to tear or collapse mid brew compared with thinner off brand papers, which matters most when brewing a full pot rather than a single cup. The unbleached brown color does not affect taste on its own, but some drinkers do report a very faint paper taste with any new filter batch until the box has been open and used a few times. Storage is simple since the filters are flat and compact, fitting easily in a kitchen drawer near the coffee maker.

Trade offs and how it compares

Compared with Melitta's own standard #4 unbleached filters, which use a simpler single layer construction, this Premium version costs more per box for the added burst resistance and finer filtration, a trade off worth it mainly for drinkers sensitive to sediment or paper taste. Against a brand like If You Care, which also makes unbleached basket style filters, the shapes are not interchangeable since basket and cone filters fit different brewer types, so the right choice depends entirely on your machine rather than brand preference. Buyers using a Natural Brew Basket style filter in an 8 to 12 cup flat bottom machine should note that filter is a different shape from this cone style Melitta paper and the two are not substitutes.

Verdict and who should pick something else

For anyone brewing daily on a cone style Melitta or Melitta compatible drip maker who wants a cleaner cup and does not mind paying a bit more, these Premium unbleached filters are a solid upgrade, matching our score of 8.1 out of 10 for fit and value. The FSC and BPI compostable certifications are a genuine plus for anyone composting kitchen waste. Buyers who own a flat bottom brewer should skip this cone shaped filter entirely and look for a basket style pack instead, and anyone who wants the lowest possible cost per filter and does not mind slightly less burst resistance can stick with Melitta's standard, non Premium #4 line.
