What to Look for in the Best Reusable K-cups

When it comes to k-cups, although they are relatively simple products, you still need to know exactly what you’re looking for. Here’s what you need to know about your options for the best reusable k-cup.

Materials

Most reusable k-cups are made of sturdy plastic and have a metal mesh filter built into the cup. Some plastic k-cups don’t have the mesh and use a paper filter to produce the best brew if you don’t like trying to wash out the tiny mesh filters. 

On the other hand, you can also buy stainless steel cups that are free of plastic, if you prefer. The one issue with stainless steel k-cups is that they may be quite hot if you need to take them out of the coffee machine right away, so be careful! Your best bet with plastic k-cups, which are the most common reusable k-cups, is to find some that are BPA-free. 

Pros and Cons: Plastic vs Metal

As mentioned before, one con about metal k-cups is that they can be HOT right out of the coffee machine. However, if you’re anything like most people, you leave your cup in the machine for longer than five minutes, so the heat may not be an issue for you. 

Another common complaint about stainless steel k-cups is that they don’t brew as strong of coffee due to the larger holes that create a filter. So, if you want to find the best reusable k-cup for stronger coffee, plastic may be the way for you to go. Either that or you can buy mini paper filters to help you make the perfect cup of joe. 

The issue with plastic k-cups (with a mesh filter) is that some struggle to clean out the mesh with ease. Always read reviews to make sure people have an easy time cleaning their k-cups, because some are easier to clean than others, depending on the quality of the product. 

And now we come to plastic k-cups, which use a paper filter. These are very easy to clean, but if you don’t want to have to buy paper filters, these are not for you!

In Conclusion…

No matter your preferences or needs, there is a reusable k-cup out there for you, possibly in this list! 

So, find your perfect k-cup and get brewing!
