The main aim of BUNN filters is to prevent the overflow of grounds into the coffee. They are a quarter of an inch taller than other filters, enabling the quick flow of water into the brew funnel and the required mixing action for an even extraction.

The standard size of a BUNN filter is 8.5 x 8.5 x 3.5 inches.

Although BUNN filters have been made to fit BUNN brewers, they are compatible with other coffee makers.

Why BUNN Filters Are So Popular

BUNN filters are a favorite among coffee makers and coffee lovers. Here are some of the reasons why:

They Are Biodegradable

If you are a stickler for sustainability, you will like that BUNN coffee filters are 100% biodegradable. This means you can enjoy a cup of coffee without contributing to the degradation of the environment.

They Make Excellent Tasting Coffee

The ability of BUNN filters to remove all sediment and coffee grinds yields a coffee of the highest taste caliber. Most people find that their coffee tastes better when they use a filter. However, a BUNN filter enhances the coffee-drinking experience.

Designed With Purpose

BUNN filters are designed to stay in place. This is an integral part of the prevention of coffee ground spillage and overflow.

Traps Oily Substances

Removing coffee grounds from your brew is one thing, but BUNN filters go even further. They are especially effective in trapping diterpenes and other oily substances that can harm your health.

This is an important feature if you are willing to give up nearly everything but coffee to lower your cholesterol content. This is because coffee can contain a great deal of cholesterol. However, if you choose the right filter, you need not worry too much about the impact of your daily brew on your health.

Other Uses For BUNN Filters

People have found a wide variety of other uses for BUNN filters. These include:

Cleaning windows and glasses – Use them to wipe these types of surfaces without leaving lint or smear marks.

Covers for food in the microwave – BUNN filters and other coffee filters are generally safe for use in a microwave. You can use a BUNN filter as a makeshift lid when reheating food to prevent making a mess. Do not, however, put a coffee filter in the oven. It will burn.

Liners for precious china – BUNN filters can be used to protect your valuable china plates from scratches or damage.

Snack holders – When you have people over, you can use BUNN filters as snack holders. They are great for serving chips, cookies, or even cupcakes.
