Question: Do I have to purchase the starter kit or can I just purchase the filters alone?
Document: I purchase this filter starter kit to keep the water going through our Keurig as free from sediment and other contaminants as possible.
This product says it is a 6 pack refill. It is not. It is just the starter filter kit with the plastic part and two charcaol filters. The seller refunded my money and asked very kindly if I would send it back. I did but at my own cost.
one star...was very very disappointed to receive my order only to see it was for the filters and not the starter kit...on the other hand i will give 5 star for being able to return the same day and get full credit AND shipping! ty...just be careful to shipper to match order with what was sent...ergo..i give overall a 3 star!
When I purchased this item the photo was a box of the actual filter assembly that came with a couple of starter disposable filters. Instead I received 6 disposable filters and no filter assembly. Be careful you're ordering what you think you're ordering.
Keurig Water Filter Replacement Starter Kit . I have bought for myself Keurig 70B and this was recommended to put in the tank. Yes It does help keep the water clean and tasting good. I would recommend on purchasing this item.
But enough was enough. Time for the filters. Now I got this kit, and my Keurig is running perfectly once again. I had to clean the lines, and was pretty discouraged at first seeing as my B-60 was still showing the Prime error. But eventually it cleared up and I've been &#34;Prime&#34; free for a month. My B-60 is running 100% again. I'll keep getting these going forward.
Helps clean the water and helps filter out contaminants. Makes your Keurig more efficient and coffee better tasting. You don't have to do a complete system clean as often. A lot less descaling needs to be done. Two filters and snap in holder for water tank included.A wise purchase.
This filter unit is an excellent add-on for the Keurig coffee makers. I am well pleased with my purchase and in fact have purchased 4 units.
I purchased this not realizing that a water filter and holder already came with the Keurig unit I had just purchased (I purchased both at the same time.). I decided to keep it in the event I need to replace the provided one at a future date. It is easy to assemble and insert into the coffee maker. A good purchase for a good value.
It,s what I needed for my coffee maker. The charcoal filters cost too much in my book but if they work thats ok.
Answer: If you already have filter holder for filters then you can purchase filters alone
