ZeroWater4-Pack Replacement Filter Cartridges ZR-004, 4 Count (Pack of 1), Basic pack

The filter works to remove all TDS (dissolved solids) and that was the purpose for me purchasing them along with a pitcher and countertop container. I've tested using calibrated TDS meters and not just the one you get with the unit. I use it primarily for my ice cubes and humidifier. A 4-pack of filters lasts me maybe 3 months total. However, caveat here is that I'm using this in Arizona where my tap water is 770 TDS and it drops it to zero but it will absolutely not last long. Initially using it for drinking but doesn't last long enough for that.

These are the only ones I'll use. I tried the off brands to save money and had to change them in half the time

Always satisfied

I’ve been drinking Zero water for years. It’s the crispest drinking water. I always fill a big water bottle to take with me when I’m not home so I don’t have to resort to plastic bottles.

We can't waste our money on generic filters so we the bought original Zerowater and they are the BEST! Thanks for a good transaction!

It last the same as it normally does and are cheaper and reliable to buy them from these guys on amazon than in store or from the company directly. Hope that helps ! :D

Great filters

Authentic replacement filters are theOnly replacement I recommend these are the only filters I will use in my zero water filter system. These are the only filters that will fit the water system precisely and not leak, I’ve had other replacement filters made by other companies nowhere near as good and therefore the price is sometimes half of the price of the authentic zero water filters. I do not recommend any of those even though the price seems quite handsome. Zero water filters are a little bit more expensive maybe even more expensive but when it comes to the quality of water they are the best quality. I’ve never had an issue with my 40 cup carafe or my water pitcher which I’ve had for I believe six years for the 40 cup carafe and about 10 years for the picture both have performed without a flaw. I recommend either we have to we have the picture in the master bedroom, and the 40 cup carafe in the kitchen both serve well in each environment.If they ever make 100 cup carafe I will definitely buy it just cannot get enough of this zero water maybe someday they’ll make a showerhead. Now that Culligan has purchased zero water we know that they have future plans hopefully a showerhead is in one of them.Thank you very much,D Petokski
