I have used these filters for years, and they work great.  Recently I bought 8-pack and they were missing the moisture indicators that tell you when they need to be replaced (Typically every 4-6 Months).  I am waiting for reply from seller to see if they will either send me the indicators, or a new pack with indicators. Without indicators, you'd have to just guess when they need replacement. Hoping they come through with good service since I've bought these filters for years.  I am giving 5 star rating because the product has always worked perfectly.  If I get missing parts or replacement/refund so I can get functioning filter moisture indicators (They are flat, small, triangular shaped foil coated pice of paper like material, that slides into the slot that is part of the fridge way in back of top shelf.), I would give them a 5 star rating for customer service which is rare these days
