From The Manufacturer

These k cup filters are working PERFECTLY in a Keurig coffee maker. They are much easier to use than the k-cup holder that requires you to take the widget out of the coffeemaker first. These are used just like a k-cup–fill and use, then rinse. They are easy to dump the used grounds out and rinse and you’re ready for you’re next cup. Having 4 is a plus so every one in the family can have theirs with out waiting on cleaning the previous one. It comes with four so you can have them at work, at home, for camping and a spare.

What experts liked

This is another great mesh filter option for a cheap price. The reason we like this one so much is that it’s available in 2,4 or 6 pack to get exactly what you need for your home.
- Eco Karma
Compatible with both Keurig 1.0 and 2.0 brewing systems, this four-piece set of reusable K-Cups by Maxware might be the perfect choice for you, especially if everyone in your home has different coffee (or tea) preferences. Now, every member of your family gets to have a dedicated reusable K-Cup filter, which eliminates the cleaning hold-up – and lets you brew your coffee just the way YOU like it.
- Koobie's Coffee
If you’re looking for an inexpensive reusable filter, the Maxware 2 fits that bill. Buy several at once, and it’s an even better deal. Considering the costs of using disposable K-cups, that potentially means cutting the cost of using your Keurig from as much as 50 cents per cup of coffee to pennies.

What experts didn't like

Doesn’t fit every coffee maker. Flimsy. Leaks from the top. Keurig 2.0 doesn’t always recognize it.

An Overview On Reusable K-Cups

If you own a Keurig or other single-cup coffee maker, it’s probably hard to imagine going back to an old drip-style machine. Since the late ’90s, these units have been popular in coffee-loving households for a variety of reasons: They deliver that essential cup of morning joe quickly and easily, with consistent quality thanks to the exact portions of coffee grounds in their K-Cup capsules. And because the capsules are mostly disposable, there’s little to no cleanup.

But for some, these same conveniences are also a liability. No matter how many flavors your pack of K-Cups has, you’re still limited to the same old ones — and none of them will be fresh ground coffee. And then there’s the environmental impact: Drink just a couple cups a day, and all those discarded capsules add up to a lot of waste. Keurig and other top manufacturers did eventually start making their disposable K-Cups out of recyclable plastic, but you still need to go through the trouble of cleaning out your pods before disposing of them — and even then, it’s debatable whether many recycling facilities will be able to process them.

Enter the reusable K-Cup. These empty containers contain filters that you can clean and use again and again, eliminating the need for throwaways. They all contain a lid that you can remove, allowing you to fill the capsule with your choice of coffee, fresh ground or otherwise.

Since you won’t be throwing them away, you won’t need to worry quite as much about their recyclability. Even so, the materials do matter. Most K-Cups in the low-to-middle price range will be made of plastic. Check that the plastic is free of BPA, an industrial chemical that can leach into foods and liquids, potentially affecting your hormone levels. Another chemical to watch out for is DEHP, a possible carcinogen. If the filter portion of the K-Cup is made of metal, make sure that it doesn’t contain lead.

Some K-Cups on the higher end will be made entirely of stainless steel or another metal alloy. Whether that affects the final product or not depends more on the construction of the filter, but you can bet that metal K-Cups will last longer.

K-Cups of both types might include gold plating on their steel filters as a selling point. Studies are mixed on whether that gold allows more antioxidants to drip down into your cup, but that’s the contention. And since gold is chemically inert, it certainly won’t hurt the taste.

Since convenience is why you bought a single-serve coffee maker in the first place, you’ll want K-Cups that are easy to clean. Will a good rinse suffice or can you expect a buildup of residue over time? Are the capsules able to be added to an automatic dishwasher? Those are questions you may want to check the reviews for. Some reusable K-Cups can technically be classified as dishwasher safe, but repeated washings may wear them out faster. Steel K-Cups are typically safe, though.

Finally, triple-check that your K-Cups are compatible with the coffee maker that you use. Keurig makers alone have a ton of different models, and different units will use different sizes of K-Cup.

The Reusable K-Cup Buying Guide

Permanent filters such as those on reusable K-Cups can have one tricky feature that takes some getting used to, especially if you like your coffee ground finely. The filter mesh is designed to be easily cleaned, and that means the holes in it are liable to be bigger — which means coffee grounds in your coffee. Luckily, this can easily be dealt with. Either start getting coffee in a coarser grind, or add a paper filter into the K-Cup. Some brands even come with add-ons that will fit just right, though it will be easy enough to make one from a standard coffee filter.
