I pre-purchased the filter and only found out it had the wrong label a year after purchase and can't return it. The label says CL10ROT33-B (1/4"), but it's actually CL10ROT33-A (1/8"). I have uploaded photos showing the old filter that I removed and the replacement. They have the same item numbers and markings, but different fitting sizes. I contacted Omnipure and they said they are not responsible because they sell to suppliers and the suppliers do what they want. And they said that there are counterfeiters too. So you have no idea what you're getting when you buy Omnipure. I will never buy this brand again. Mine was going to the bin (I bought 2) and I just ordered a different brand filter from Filters Fast. More expensive in theory, but the last two Omnipure filters were a waste of money. And who knows if they are real Omnipurs.
