The filter is one of the last things that touches your coffee before it reaches your cup. It affects flavor, body, and even the health profile of what you drink. Paper filters produce a clean, bright cup. Metal filters produce a fuller-bodied, richer cup with more sediment. Cloth filters sit between the two.
The right choice depends on what kind of cup you want, how much you care about convenience, and whether cafestol is a concern for you. For more on how brewing method affects cup character, see our coffee brewing methods guide.
Filter Comparison at a Glance
| Factor | Paper Filter | Metal Filter | Cloth Filter |
|---|---|---|---|
| Cup character | Clean, bright, light body | Rich, full-bodied, some sediment | Clean with body, sweet notes |
| Oil removal | Removes nearly all oils | Lets oils pass through | Removes most oils |
| Cafestol | Removes cafestol | Cafestol passes through | Removes most cafestol |
| Reusable | No — single use | Yes — rinse after each use | Yes — wash and dry after use |
| Cost | Low per unit, ongoing | Higher upfront, no ongoing cost | Moderate upfront, no ongoing cost |
| Cleanup | Easy — discard with grounds | Quick rinse | Thorough rinse required |
Paper Filters
Paper filters trap coffee oils and fine particles as the brewed coffee passes through. The result is a clean, clear cup with light body, bright acidity, and no sediment. The paper absorbs the oils that carry cafestol, a compound linked to higher LDL cholesterol levels. If cholesterol is a concern, paper-filtered coffee is the lower-risk option for daily drinking.
Bleached paper filters are white and go through a chlorine or oxygen bleaching process during manufacturing. Some drinkers notice a faint paper taste from bleached filters. The fix is simple: rinse the filter thoroughly with hot water before adding coffee. Unbleached paper filters are brown and skip the bleaching process entirely. They are the safer choice if you are concerned about any residue from the bleaching process.
Paper filters are brewer-specific. A Hario V60 filter does not fit a Chemex. Buy the filter designed for your brewer. For more on pour over brewing and which brewer suits you, see our pour over coffee makers comparison.
Metal Filters
Metal filters use a fine mesh to stop grounds while letting coffee oils and fine particles pass through. The result is a fuller, heavier-bodied cup with more richness, visible oils on the surface, and a small amount of sediment. This is the character French press delivers. Metal-filter pour over drinkers often prefer it for the same reason.
Because metal filters let cafestol through, daily metal-filtered coffee may have a measurable effect on LDL cholesterol over time. For most healthy adults drinking one to two cups per day, this effect is modest. For anyone with existing cholesterol concerns or drinking four or more cups per day, it is worth discussing with a doctor. Metal filters are reusable indefinitely. Rinse them immediately after use. A weekly soak with espresso cleaning powder removes oil buildup. For more on espresso machine maintenance and cleaning, see our espresso machine maintenance guide.
Cloth Filters
Cloth filters remove more oils than metal but fewer than paper, producing a cup that is cleaner than metal-filtered coffee but with more body and sweetness than paper-filtered coffee. They are reusable and biodegradable. The trade-off is maintenance. After each use, the filter needs a thorough rinse to remove all grounds from the fabric. Grounds left in a cloth filter ferment quickly and affect the flavor of subsequent brews.
Which Filter Is Right for You?
Choose paper if: You want the cleanest, brightest cup with no sediment, you are concerned about cholesterol, or you value easy cleanup over cost savings.
Choose metal if: You prefer a full-bodied, rich cup with more oil and flavor intensity, you want to stop buying filters, and you are comfortable with occasional sediment.
Choose cloth if: You want a middle-ground cup with more body than paper but cleaner than metal, and you are willing to maintain the filter carefully after each use.
All three produce excellent coffee from quality beans. The filter shapes the cup. The bean determines what is in it.

Frequently Asked Questions About Coffee Filters
What is the difference between paper and metal coffee filters?
Paper filters trap coffee oils and fine particles, producing a clean, bright cup with light body and no sediment. They also remove cafestol, a coffee oil linked to higher LDL cholesterol levels. Metal filters let coffee oils and fine particles pass through, producing a fuller-bodied, richer cup with more intensity and some sediment at the bottom. Metal filters are reusable. Paper filters are single-use. The choice comes down to what kind of cup you prefer and whether cafestol is a concern for you.
Are metal coffee filters healthier or less healthy than paper?
Paper filters remove cafestol, a compound found in coffee oils that has been linked to higher LDL cholesterol levels in some studies. Metal filters let cafestol pass through into the cup. For most healthy adults drinking one to two cups per day, the difference is modest. For anyone with existing cholesterol concerns or who drinks coffee heavily throughout the day, paper-filtered coffee reduces cafestol exposure. Unbleached paper filters avoid any potential residue from the bleaching process and are the choice recommended by most health-conscious drinkers who use paper.
Does the type of coffee filter affect taste?
Yes, significantly. Paper filters remove coffee oils that carry a lot of the body, richness, and aromatic depth of the brew. The result is a clean, bright, light-bodied cup. Metal filters let these oils through, producing a heavier, richer cup with more intensity. If you switch from paper to metal in the same brewer with the same coffee, the cup tastes noticeably different. Neither is better overall. Paper suits drinkers who prefer clarity and brightness. Metal suits drinkers who prefer body and richness.
Do I need to rinse a paper coffee filter before using it?
Yes. Rinsing a paper filter with hot water before adding coffee removes the papery taste that some drinkers notice, particularly with bleached white filters. Place the filter in your dripper, pour hot water through it into your mug or server, discard the rinse water, and then add your ground coffee. This also pre-warms the dripper, which helps maintain brewing temperature. The rinse takes about 20 seconds and noticeably improves the cleanliness of the cup.
How do you clean a metal coffee filter?
Rinse the metal filter immediately after use under hot running water to remove the coffee grounds before they dry. A soft brush helps dislodge grounds caught in the mesh. Once a week, soak the filter for 10 to 15 minutes in hot water with a small amount of espresso machine cleaning powder or baking soda to dissolve the coffee oil buildup that accumulates in the mesh over time. Rinse thoroughly after soaking. A metal filter that is not cleaned regularly becomes coated in oxidized coffee oils that produce a bitter, stale taste in subsequent brews.
