It's the Price i have only been using the filter for a couple of weeks but, as best I can tell from this brief experience, it works as well as the expensive brand recommended by the refrigerator manufacturer at a quarter of the price. (I'll know more in 6 months time.)

My replacement filters At first when my package arrived I was very skeptical on the name Glacier Fresh. I had never heard of this company before, but when we installed both filters, we were pleasantly surprised how easy it was. Not only that, they work terrific and filters both designed to fit perfectly. We are very pleased with this company and the products they offer.

Satisfied customer support experience. I ordered 3 filters for our Fridge. Only one came. I wrote to customer support asking about the rest of the shipment showing the order for 3. They sent 2 more shortly thereafter. Was very glad they delivered as promised. I appreciate companies who respond to the customers communications promptly.

Nice well made product. Poor (non-existent) customer support Here is the exact text sent to Glacier: Today I set up my new GF-RVWS001 which was purchased thru Amazon. I was a disappointed about a couple of things. I noticed the main cap was sitting a bit crooked. After struggling to remove it I found it was cross threaded. Once put on correctly it seems to seal. The 6001 fitting was missing the black O-Ring. I was able to use one I had on hand. The 6002 fitting was missing the small white O-Ring. I was able to repurpose the one from the 6003 fitting. Collectively these deficiencies make me wonder if I am the first owner of this unit. Here is their response: Hello. Sorry, we are an independent website, not Amazon, we suggest you contact the customer service of Amazon store directly, they will help you to deal with the problem, thanks for understanding. When I replied with a screenshot showing Amazon directing me to the Glacier website I received the following response: Hi, In this case,you could contact with the AMAZON front desk for help. Thank you for your understanding. Disappointing, I will reach out to Amazon for further help.

Ordered filters for my refrigerator. Ordered filters for my refrigerator. Although they were back ordered they still arrived quickly and the staff kept me informed throughout and gave me the option to cancel or order an alternate. Very keen price, good service and quick delivery. Definitely will use them for all future orders.
