What water filter does my fridge use?

Your Samsung fridge's water filter keeps your water crisp and clean. Generally speaking, you should plan to change your fridge's filter every six months or so, depending on usage. Samsung fridges are equipped with an alert to let you know when it's time for a change. But how do you know what type of filter you need? Take a look at your old filter - if it has a circular profile, it's an HAF-CIN, and if it's a square profile, it's an HAF-QIN. Older models may also use HAF-CUI filters. But most importantly, always use official Samsung water filters, not third-party products! Samsung filters can be purchased on Samsung.com and also set up as a subscription option, so you receive a new one every six months!
