Reusable metal filters simply are not fine enough to catch everything that is poured into them, meaning they let important elements through the filter and into the cup, such as oils and micro-fines.
Coffee has also been accused of raising cholesterol. Specifically, it's said to raise LDL, "the harmful type of cholesterol," says NBC News' Merritt McKinney. However, it's the oils that sneak through metal filters that are truly to blame.
Micro-fines are tiny granules of coffee that are small enough to slip through the holes of the filter, which give the cup a darker, more cloudy appearance. They also make the flavor of the cup more rich and bold, like coffee brewed in a French press, and settle at the bottom of the cup, leaving a bit of sediment (also like French press coffee).
Metal filters can save you money in the long run, but are a bit more difficult to clean.
Paper filters cost more over time, but are practically mess-free.
Metal filters produce a more robust and visually darker cup of coffee, which contains more oils and sometimes small amounts of sediment.
Paper filters produce a brighter, sweeter cup of coffee with little or no sediment or oils, helping cut out the bad cholesterol found in coffee.

- According to Harvard Health Publications, paper filters are more effective at eliminating diterpenes than permanent or cloth filters.
Other Uses for Filters
"Real Simple" suggests using clean paper coffee filters to clean windows and mirrors for a lint-free finish, and as spacers between fine china to prevent scratches. You can also poke a hole through a coffee filter and slide it onto a popsicle stick or ice-cream cone to prevent messy drips. In the kitchen, use coffee filters to strain wine when a cork has broken into the bottle.

we’re talking about size 4 cone-shaped permanent filters. What does the “4” represent? Just the size of the filter, which is a standard size.
If you are using a paper filter, you should at least rinse it out before using it, just to wash away the dust that can get into your coffee that sticks to the paper

- 12 Health Benefits of Coffee
Coffee boosts your physical performance. Have a cup of black coffee about an hour before workout and your performance can improve by 11-12%. Caffeine increases adrenaline levels in your blood. Adrenaline is your body’s “fight or flight” hormone which helps you to prepare for physical exertion

- Regarding taste the coffee could taste a little less rich with paper filters because it won’t allow the coffee oils through the filter. Since taste is subjective you could see this as an advantage. Some others prefer stronger, full-bodied flavors and thus probably tend to permanent filter

- Paper filters are the most common and best way to brew coffee utilizing the drip method
Paper filters do the most thorough job in removing particulates and thus effectively trap bitter sediments for a smoother less bitter cup of coffee
In addition, paper filters allow you to use any type of grind while permanent filters require courser grinds.
Finer grind coffees have a larger surface area exposed to the water so it provides a richer cup of coffee.
Potentially Healthier -- Scientific studies have indicated that paper coffee filters play a crucial role in eliminating the cholesterol raising factor of coffee. Permanent filters, on the other hand, allow the cholesterol raising oils to filter into the cup.
Environmentally Friendlier-- Paper filters are 100% biodegradable while permanent filters are not.
Cone Vs. Basket
The shape of the filter that you need to use is dictated by the shape of the filter holder within your coffeemaker. There are two different shapes of holders/filters: Cone (round top gradually tapering down to the bottom) and Basket (circular holder/filter with a flat bottom).
In general, cone shaped holders with cone shaped filters are recommended as the design ensures optimal coffee saturation and extraction versus basket shaped holders/filters
#1 Size Filter: Fits 1 cup electric cone coffeemakers
#2 Size Filter: Fits 2 to 6 cup electric and 1 cup pour-over cone coffeemakers
#4 Size Filter: Fits 8 to 12 cup cone coffeemakers
#6 Size Filter: Fits 10 cup pour-over cone coffeemakers
Paper filters also allow you to use any type of grind while permanent filters require coarser grinds
Other benefits of paper filters versus permanent filters include easier clean-up, more sanitary, and more environmentally friendly. In addition, studies have indicated that paper filters play a crucial role in eliminating cholesterol-raising factors from coffee.
Alternative Uses for Coffee Filters

- Ist turns out, it’s all to do with those crimped edges of the filters. Yes, they really are there for a reason – not just to look pretty.
By turning folding these edges over, the filter has extra support when in the machine, meaning it won’t burst when it brews your coffee.

The different types of paper:
Natural brown : In its natural form, all paper is brown colored, so brown filters are completely unprocessed. Other than aesthetics and processing, there are no other differences in color.
White : White paper filters are processed to get that clean, white shade. Chlorine bleaching or natural oxygen bleaching are common methods for whitening paper. Generally, better quality paper ones do not use chlorine bleach.
Bamboo : Bamboo fibers can also be used. Bamboo is a naturally renewing resource that grows much more quickly than the type of tree used for paper pulp.
Permanent Filters
Gold toned : Gold plated filters are made out of stainless steel with gold plating. Especially good-quality gold versions are available plated with real 23-carat gold. The metal mesh lets in very small particles of coffee grounds to the finished product. The oils in the coffee remain, adding additional flavor.
Nylon : Nylon coffee filters are made of the synthetic fabric. They are lower in price and quality when compared to the metal permanent option, and can give off an acidic taste over time.
Cloth Filters
Cloth filters are made of natural cotton, hemp, or muslin fabric. The pores on cotton filters are slightly larger than those on paper filters and smaller than the pores on permanent ones
There are many different sizes available, depending on how much coffee you want to make. Cone filters come in sizes 1, 2, 4, and 6; larger filters for coffee makers are sized to make 4-6 cups or 8-12 cups.

- Depending on the coffeemaker's manufacturer, a cone filter is shaped with a large, round opening that narrows down into a point. This filter type is commonly used with a drip coffeemaker. Hot water drips down into a coffee-filled filter. The hot water moves through the coffee grounds and eventually drips out of the coffeemaker as coffee.
Number 2 size filters work with electric coffeemakers equipped with four to six cups
Number 2 size filters work two-cup non-electric makers.
Number 4 size filters fit electric coffeemakers with eight to 12-cup capacities.
Number 6 size filters work with 10-cup non-electric coffeemakers.
Shape Benefits
The cone shape contributes to quality cups of coffee. Coffee concentrates down at the filter's narrow point. The coffee's density creates more movement from the dripped water across the coffee's surface area. More water saturates through the coffee grounds, as opposed to just slipping in between the individual grounds. As a result, coffee drips downward with more flavor absorbed from the grounds.
