I don't take them out. I let them empty, then I rapidly jackhammer the entire dispensor onto my counter. not hard. you don't want like a loud bang. you want to do it light and fast for like 30 seconds

ZeroWater's 5-stage replacement filters are valued for producing very clean-tasting water, and they can be useful in hard-water areas or for plant watering. The main drawback is how quickly they can wear out, with replacement sometimes needed every couple of weeks and the cost adding up fast. Flow problems also come up with the newer tapered design, though shaking the filter, lightly tapping the dispenser, or pouring water directly onto the filter can help restore drainage. These filters are only compatible with ZeroWater systems, not the newer Culligan ZeroWater units.

super expensive but so effective, the filtered water tastes so good... I live in NJ and we needed to replace filter every 1-2 weeks. So we gave up and now drink costco bottled water (I know, micro plastic Big Grin)

$47.59 for me after the 15%, good deal. These are my first refills - I haven't had a zerowater container for long.

I'm still really curious about the one consumer reports test that showed these adding a lot of microplastics into the water, compared to other branded products. I haven't seen anyone else test or verify this claim.

No, these filtering water to be near empty, almost to the extent of distilled water, isn't terrible for you if you're consuming a normal diet. Just don't rely on this if you're doing a lot of strenuous, sweaty work - in that case more food or electrolyte tablets can help, if not also going for straight tap water.

I think Culligan has ruined these already. My last 4 filters have stopped flowing extremely fast and they seem to have a lot of air entrapment. RIP.

Take the filters out and shake them around. I think the filtration beads settle and block the flow. You may have to do this every few weeks, but they should flow like new after a proper shake.

It's right there in the original post. The title has the 5% discount. The description adds the 15% discount.

Oddly ymmv, no coupon on the 6 pack but is on the 8 pack and 12 pack for me(8 pack is 66.71 with Max s&s, 12 is 100.77 coupon worked for 1 of each, not as low a price but I'm now set for quite a while and these have an extended storage life so thanks OP even if I didn't get the mentioned deal 😂.)

I've been using Zero Water for well over a decade. I noticed the trapped air and flow rate issues as soon as they introduced this new design where the bottom of the filters taper inward. I'm still using the older style where the sides come straight down to the bottom. These never create the trapped air issue.

Honestly a good deal for these. I use them to water my plants as I live in a very hard water area. I would not use this for drinking water, it's not good for you (it has 0 particulates so it leeches nutrients out of your body) and would be insanely expensive.
"...leeches nutrients out of your body..."

Huh? Can you please provide links to support this idea? Or is this coming from some social media "influencer"?

Darn, might be more of a YMMV situation. I'm only seeing any coupon on the 3-pack for 37.49.

Same here, bummer. Deal might be dead, or it might be targeted.
