If you regularly brew home-made coffee, then one of the random but important questions you may have is: ‘how often should I change my coffee filter?’

Is a coffee filter actually necessary, what exactly is it used for?

Although there are a few methods of brewing coffee that may not directly involve the use of a filter, still, fact is that the common, easy, and efficient methods of brewing coffee involve the use of filters.

Brewing methods that make use of filters involve pouring of hot water into the grounded coffee beans that must have been poured into the coffee filter which perhaps has been placed on a coffee basket. The hot water runs through the grounded coffee beans dissolving and carrying the soluble components along through the filter and the brewed coffee is gotten in a pot.

The basic purpose of the filter used during the brewing is to hold the insoluble particles of the coffee beans and allow the passage of the dissolved liquid into a container. If the coffee filter is not used, the particles will just pass through along with the water and you’ll just have your coffee with a lot of undesired particles inside.

What determines how often you have to change your coffee filter?

How often you will have to change your coffee filter will depend on a major factor, this will largely determine the frequency of replacing your coffee filter.

Paper filters

These paper filters are usually produced in certain sizes and shapes based on the type of coffee maker basket they are to be used along with. There is the think cone type and the flat -bottomed variety. They can also vary in thickness, the thicker ones are usually more expensive than the thinner ones, the types made of thinner paper will filter less of the coffee oil, while the thicker ones filter out the oils better.

Regardless of what brand or thickness the paper filter is, ideally, it should not be used more than once. Once you have used it to brew your coffee, you remove it from the coffee maker basket and dispose it. Although some people might try to use the paper filters more than once, it is not very okay to do so. Basically they were designed to be used just once. They are inexpensive and they come in multipacks that you can easily buy in stores and use whenever you need to.

It is therefore best to use once, remove and dispose when using paper filters.

Metal filters

These are much more durable than paper filters, they can last for a long time. They are made from finely woven wire mesh, it is commonly stainless steel that is coated with gold plating and they are called ‘gold tone’. Just like the filter papers, they are also produced according to specific sizes and shapes so as to be used along with certain types of coffee makers. They come in cone shapes or flat-bottom shapes. Metal filters usually filter out the grounds but do not filter the oil part out, this makes the coffee brewed using metal filters to be better flavoured retaining the oils.

Nylon filters

They are also non-absorbent like metal filters and they filter the grounds but not the oils since the nylons are not absorbent like paper filters. They also come in cone and flat-bottom styles. One of the advantages of nylon filters is that they are more affordable than metal filters, although not as durable, but can still be used for a long time if they are carefully cleaned and handled.
