Different sizes of Ninja Coffee Maker Filters

Ninja coffee maker filters come in a variety of sizes. Yet, how do they differ? Let us find out.

First, let me say with certainty that Ninja Coffee Machines do not have extra paper filters. That’s correct. They come with a reusable filtration apparatus that collects coffee grounds and keeps them out of your beverage.

This is not to say that these Coffee Machines do not require filters. They have an integrated water filtration system that filters chlorine and other pollutants from the water before it reaches the coffee grinds. This also guarantees that the flavor of your coffee is genuine and original.

But what if you want to make varied volumes of coffee or use different coffee grounds? Your filtering basket may require various additional filter sizes.

Here are three main dimensions:

Standard Filter Size (4 inches) 

This is the most common size that fits most Ninja Coffee Makers models. It has the capacity of 12 tablespoons of coffee grounds and brews up to 12 cups.

Large Filter Size (4.5 inches)

This slightly bigger size fits newer Ninja Coffee Makers models, such as CFP301 and CFP201. This size can keep up to 14 tablespoons of coffee grounds.

Extra Large Filter Size (5 inches)

This is the biggest size that fits some older models and many new ones. It can hold up to 16 tablespoons of coffee grounds and brew up to 16 coffee cups.

Types of Ninja Coffee Maker Filters

Well, as I explained, there are different sizes of filters for Ninja coffee makers. Similarly, there are also other types of these filters.

Water Filter

A water filter can remove chlorine, lead, mercury, and other impurities from your tap water that affect the flavor and aroma of your coffee. These are usually external filters and purify water before entering the coffee maker.

These filters include: 

  • A pitcher filter
  • A faucet filter
  • An under-sink filter 

Paper Filters

Paper filters are one of the most common types of filters. These are disposable. You can use them as a convenient option for a hassle-free cleanup. However, these filters can sometimes leave a papery taste in your coffee.

K-cup Reusable Pod

If you have a Ninja DualBrew Pro System, you can also use K-cup pods to brew single-serve cups of coffee with different varieties and flavors. 

However, you can use reusable ones instead of buying disposable K-cup pods. In this way, you can save waste and some extra money. Moreover, these pods will allow you to fill your machine with more coffee grounds.

Permanent Gold-tone Filter

Another option for brewing coffee with your Ninja coffee maker is a permanent gold-tone filter.

This filter is made of stainless steel mesh coated with gold plating that prevents oxidation and enhances durability.

A gold-tone filter can also improve the taste and quality of your coffee by allowing more oils and flavors to pass through.

Determining the Correct Filter Size for Your Ninja Coffee Maker

As a proud owner of Ninja coffee, I give special consideration to my machine. I know how important these are to keep me up during a tired morning.

Recently, I bought a couple of K-cups and thought of sharing the entire process with you. The way I determine the size and need of my machine – these are the steps that you must follow to find out the correct filter size:

  • Check your coffee maker’s model number and manual. Different models may require different filter sizes.
  • Generally, use a filter size two sizes smaller than your coffee maker’s capacity. For example, if you have a 10-cup Ninja coffee maker, you should use an 8-cup filter.
  • Consider the type and amount of coffee grounds you use. If you like strong, bold coffee, use a larger filter to hold more ground. If you use a fine grind, you may also need a larger filter size to prevent clogging.
  • Experiment with different filter sizes until you find your perfect brew. You can use standard (4 inches), significant (4.5 inches), or extra large (5 inches) filters for your Ninja coffee maker. Just ensure they fit snugly in your machine and don’t cause any spillage.
  • Always read the user manual. Many times the companies are kind enough to send a DIY guide that mentions the correct size of the filter.

Factors to Consider When Choosing a Filter Size

You must consider several factors when selecting the correct filter size for your Ninja Coffee Maker.

Here are some things to keep in mind when choosing a filter size:

Basket Size

The size of your coffee maker’s filter basket will determine your desired filter size. A larger basket will require a larger filter, and vice versa.

Brew Strength

If you like your coffee strong, consider using a smaller filter. A larger filter will result in a weaker brew.

Paper or Reusable

Decide whether you want to use paper or reusable filters. Paper filters are disposable and easy to clean up, while reusable filters are eco-friendly and cost-effective over time.

Brand Compatibility

Make sure your filter size is compatible with your specific model of Ninja Coffee Maker.

The Strength of Your Coffee

Another thing you need to consider is how strongly you like your coffee. If you prefer a mild or medium flavor, stick with the standard filter size (around 4 inches in diameter).

In contrast, opt for a larger or extra-large filter size if you like a bolder flavor. These filters can hold more coffee grounds and give you a richer taste.

The Type of Your Grind 

The type of grind you use for your coffee is also an important thing that you should keep in your mind.

If you are a fan of coarse grinds, such as French press or cold brew, you can go with any filter size without any problem.

However, if you use a fine grind for espresso or drip brew, you should choose a larger or extra-large filter size.

Maintenance and Replacement of Ninja Coffee Maker Filters

Just like you clean yourself daily, your Ninja also needs caring. And it is in the best interest of your machine if you properly maintain and replace its filters regularly. 

Here is how you can do it:

Regular Cleaning

Clean your filter basket regularly to prevent clogging and ensure the best flavor. You can clean the filter basket with warm water and soap or run it through the dishwasher.

Replace Filters Regularly

Ninja Coffee Maker filters should be replaced every 2-3 months or after 60 uses to maintain optimal performance. The same goes for the built-in water filtration systems of the machine.

Use High-quality Filters

Using high-quality filters is necessary for the best flavor and to prevent clogging. Cheap filters may tear or not fit properly, resulting in a stronger or more bitter-tasting coffee.

Check for Wear and Tear

Inspect your filters regularly for signs of wear and tear, such as tears or holes. If you notice any damage, replace the filter immediately.
