iPartsPlusMore K-Carafe Reusable Coffee Filter and 3 Reusable Cups Compatible with K-Cup for Keurig 2.0, K200, K250, K300, K350, K400, K450, K460, K500, K550, K560

I don't have any problem with these reusable coffee filters. They seem to be well made and work fine in my Keurig 450. However, I think there is a problem with the strength of the coffee using these compared to the original K-cup version. Perhaps my coffee ( Dunkin Donut original blend) is too coarsely ground to give the full-bodied strength that the Duncan Donut k-cups do. When I use a k-cup, I can dispense 8 ounces of water through the k-cup, lift the Keurig handle, select 6 ounces and dispense that through the same k-cup for a 14- ounce cup of coffee from one k-cup pod that is a very good cup of coffee. To get that same strength of coffee using these reusable coffee filters, I can only dispense 8 ounces of water through the reusable coffee filled pod. The k-cups must have a finer ground coffee that is packed tightly into the k-cup. I guess you could use the carafe-size pod to get a larger cup of coffee, but the amount of coffee you would then use to produce the same result as the k-cups do would make your coffee purchase as costly as purchasing the k-cups. Finally though, these reusable coffee filters work great if you just want an 6- or 8-ounce cup of coffee.

Reading some other reviews, and asking some questions, I almost didn't buy these, as many users said the larger 4 cup filter did not work. Well I did some more homework and decided to try these, and then would try hack my K450 coffeemaker to accept it. Apparently, the coffeemakers are looking for a color and one possible hack is to put a colored round sticker on top of the filter cup. There are others on You tube to watch. Anyway, apparently the red/orange color of the 4 cup filter fooled my coffeemaker, and it brought up the menu. The small one-cups of course work great too. I love these, now that I can grind my own coffee when I just want one large cup for myself instead of making a big pot with the BUNN. For me it was worth the risk of buying, as they work great.

I own the Keurig 2.0 K200 model. I was a little skeptical ordering these because reviewers said the carafe didn't work with their 2.0 models. I had no problems whatsoever with the carafe or the regular size. These are decent little reusable filters. The lid is just a "seal shut" kind of design which only requires you to press down. I know some kinds "click" but these do not. I prefer a stronger cup, so packing these puppies full of my preferred blend gave me a decent cup.

Both the carafe and single cup filters work on my K250 (newer model), without having to install a freedom clip. I bought these to have backups to another set I had purchased before. The only reason I dropped it one star is that these filters do not make a strong enough cup for my tastes. However, it isn't too bad, and the savings you get from buying ground coffee over K-Cups pays for this item in less than a month.

OMG this is the first cup I have brewed with these but it is sooo good. I feel like I haven't had a real cup of coffee in a long time. I used a tablespoon of grounds in the single k-cup but I used it twice to fill a 14oz travel mug. It is delicious! I think since its almost all filter it makes a much stronger brew than the poked hole in the disposable k-cups. I may experiment with using less coffee just to see since there were no directions on how much coffee to use and I don't want to waste. Easy to fill and clean too.

I would love to give this product 5 stars but only the purple cups worked with my keurig. The orange carafe cup kept giving me an error message. I googled and youtubed to see if there was a special way it had to be inserted but to no avail. The purple cups work amazingly well. They brew great every time and produce a delicious cup of coffee; no complaints there. I have a Keurig 2.0 K400 series and the orange carafe cup does not work in it.

I love the resizable factor and saving money. I DO NOT like that emptying these is literally the most tedious task. I don't like the just spray out he used grounds into the sink (nobody wants clogged pipes) so we empty them in the trash. It's a pain in the ass, to put it mildly. I literally have to beat these things on the side of the trash can.

Nice to have a filter that works with the Keurig version 2.0. However, the K-carafe filter broke at the hinge within days. So you must be careful when opening the lid. No extra force was used, just not that well made. The individual filters are an added bonus, but three of them are not necessary. They seem to be better made than the k-carafe size.
