What is the right coffee filter? Choosing the right coffee filter can be confusing and especially when you have little or no information about the various coffee filters in the market. From metal to bleached filters, you may find yourself unable to pick the right one. But don’t worry because we have you covered. This guide takes you everything you need to know about choosing the right coffee filter. So, make sure to read it to the very end.
Bleached vs. Unbleached
There are many bleached and unbleached coffee filters in the market. But is there a difference between them?
These are papers that have undergone a bleaching process that makes them appear white. Two products are used in the bleaching process. That is oxygen and chlorine.
Chlorine is used to whiten the filters, but it does not do an excellent job compared to oxygen. Using oxygen results in high-quality bleached coffee filters. So, if looking for quality bleached coffee filters, then make sure to look for filters that are bleached using oxygen.
Unfortunately, bleached coffee filters are not friendly to the environment. They can pollute the environment when discarded, even though a small amount of bleach is used.
Oxygen-based tend to be the best as oxygen is much more environmentally friendly compared to chlorine.
Unbleached filters don’t have that bright look bleached filters have. They are a bit dark, more natural, and much more environmentally friendly. These filters don’t undergo any manufacturing process, and this means when they break down, they are not harmful to the environment as bleached filters.
For the best experience with unbleached coffee filters, mainly to avoid the taste of paper in your cup of coffee, consider doing the following:
- Place your filter in your coffee maker.
- Pour a little water into it to wet the entire filter.
- Discard the water you used to wet the filter and brew your coffee.
If you follow these three steps all the time, you won’t be able to tell the difference in a cup of coffee made from a bleached filter and that made in an unbleached filter.
Take into these considerations
- Bleach does not affect taste
While many people believe using bleached or unbleached is likely to hurt the taste of coffee, that is not true. The amount of bleach used is very low to impact the taste of your coffee or cause undesirable side effects.
- Quality is king
The quality of the filters you go for means a lot. You select the right ones, and you are sure to enjoy a delicious cup of coffee. You save on your cents, and you will only have yourself to blame. Often thicker filters, although a bit expensive, are the best because they don’t let water pass through fast. On the other hand, thinner filters are not suitable as they let water through fast hence hurting the brewing process.
Now that you are aware that quality is king, which filters are pocket-friendly? Bleached or unbleached? If you want to save a little money on your filters, the best bet is picking filters bleached using oxygen that are a bit thicker. But if you want to remain environmentally friendly, choose unbleached filters. Keep in mind that you will pay more if you go for unbleached filters.
So, which one is best?
Honestly, there is no clear winner between bleached and unbleached coffee filters. Both are great and will yield a delicious cup of coffee. Bleached filters undergo a manufacturing process, but the bleach in them has no impact on your precious liquid. Unbleached filters, on the other hand, are environmentally friendly.
Basically, if you pick the right size and the correct thickness, you can rest assured to enjoy great cups of delicious coffee all the time.
Paper vs. Metal
Which filter will get the job done? Paper or metal? There is much debate about these two filters in the coffee world. Some recommend paper filters, while others go for metal filters. So, which is the best option? To help you decide which filter is suitable for you, we take you through a few questions.
- Which coffee filters cost more?
Metal filters are a bit expensive compared to paper filters but worth an investment if you are a big coffee drinker. Paper filters are cheap, but you must keep buying them. If you want to save more in the long run, it best to go for metal filters.
- What about the environment?
If you are concerned about mother earth, by all means, go for metal filters. They are not only recyclable but also last longer. Here, metal filters are the obvious winner.
- Which coffee filter is easier to clean?
While this one can be subjective, a paper filter is an obvious winner. Why? You just simply lift the filter out and discard it. When it comes to a metal filter, you must dump it before rinsing it after each pot. Additionally, you have to put it through cleaning cycles in your dishwasher or sink to make sure it is always ready for use.
- Which one is better?
If you are concerned about your health, paper filters are the best. Experts say that they remove cafestol, an oil that is known for raising cholesterol levels.
However, there are some concerns that the bleach in paper filters may get into your coffee. If worried about bleach in your coffee, consider switching to unbleached paper filters.
If you choose metal filters, you don’t have to worry about bleaching agents finding their way to your cup of coffee.
- Will the type of coffee filter affect the taste?
Metal and paper filters will produce coffee that tastes very different from one another. This could impact which one you go for. Metal filters don’t remove as much of the cafestol from coffee as paper filters do. This means more oil end up in your coffee; hence, you get a much bolder and richer coffee compared to what you get with a paper filter. So, if thirsting for a fuller body cup of coffee with a bold flavor, metal filters are a sure bet.
On the other hand, paper filters remove much of the cafestol resulting in a much brighter flavored drink that is much lighter in body. Many drinkers prefer this taste. You may also want to be careful with paper filters as your coffee can taste paper. The best solution to this is rinsing filters with hot water first.
The bottom line, go for metal filters if thirsting for a much bolder cup of coffee and not worried about what is filtered. If worried about what is filtered and prefer a lighter cup of coffee that is much brighter in taste, buy paper filters.
Things to consider
The shape of your filter
The types of filters tend to be the favorite among more dedicated homebrewers. There are available in two basic types. One shaped like a standard cone and the other has a round opening with two sides that taper into a shorter line.
The one shaped like a standard cone is primarily used for manual brewing tools, while the other one is commonly adopted by permanent filters designed for automatic brewers. Both filters get the job done.
Also known as flat-bottom filter or cupcake, these filters are either shaped like buckets with smooth edges or like cupcake liners with a fold around the sides.
Note that the openings at the top basket filters can be larger than the surface area at the bottom, but the difference is not nearly as extreme as conical filters.
Disk filters are commonly used for AeroPresses as a replacement or alternative for the French Press filters. Compared to the other filters, disk filters are a bit smaller and do not follow the standard sizing rules.
Cone vs. Basket
Which is the best option for you?
Cone filters are the obvious winner. Why?
They have a narrow bottom, unlike the basket filters, which have a wide flat bottom. The narrow bottom in cone filters prevents coffee grounds from been spread out, hence guaranteeing even extraction. This means conical filters force hot water to travel through the coffee ground more effectively. For this reason, cone filters tend to be more expensive and worth your money.
What about sizes?
Often bucket filters are sold in 8 – 12 size filters. However, when it comes to conical filter, there are different standards which come in #1, #2, #4 and #6. These numbers represent the tools you can use the filter with. Here is how it works:
- #1 Size Filter: For one-cup coffeemakers (both electric and non-electric)
- #2 Size Filter: For 2 to 6 cup electric coffeemakers or 1-2 non-electric coffeemakers
- #4 Size Filter: For 8-10 cup non-electric coffeemakers or 8-12 cup electric coffeemakers
- #6 Size Filter: For Fits 10+ cup pour-overs/ non-electric coffee maker
Often, #2 and #4 are the most common sizes as they cover the brewing needs of most people.
Your Coffee Brewing Method
Most coffee makers come with coffee filters and in most cases, metal filters. Some let you order one instead of using a paper filter, and there are those that don’t make metal filters for their machines like pour-over systems. Doing your homework in advance can help you avoid such brewers.
Basically, whether you go for a paper filter or metal one, it all depends on your taste. We recommend you try both and then pick one that works best for you.
