Review: Buy These - I have a pond and to reduce the heavy metals when topping up I use these in my filtration , does the job good quality and the value for money means I can change my filters more often than recommended , easy to use quick delivery 😀😀😀
Review: Excellent - easy to fit and much better tasting water. Great customer service too! - I'm really pleased with it! After a few days for the tiny bubbles (which made the water look cloudly at first) the water is noticeably improved over our tap water supply and it's now my go-to source for drinking water. No more expensive bottled water, no more plastic waste! So good I bought a second one for our office. There was a small broken connector when it arrived but I'm still giving 5 stars as the customer service was excellent and they got me a replacement part very quickly

**Q: Is the water supposed to come out foggy and fizzy?**
A: Hi Ann,

Yes, for a week or two, the water might come out cloudy due to the trapped air bubbles in the system. In time, these will dissipate and your water will begin to clear up. If you have any questions or need additional assistance, please contact us at support@123filter.com or call us at (678) 261-7611.

**Q: Will these cartridges work on an existing Culligan RO system?  How will I know?  Thanks.**
A: If the size of filter is the same and the end deals are the same then, I think they should work.

**Q: Can we use this package for WCC31?**
A: Thanks for the question! You can certainly use this filter pack for the WCC31. We use industry standard filters, so each of the 2.5" x 10" cartridges and filter packs are completely interchangeable with each other.

### ⭐⭐⭐⭐⭐ It wouldn't hurt to try it for 1 year. Might be surprised
*by B***N on 8 December 2025*

No problems with my first set, no problems with my second set all works well. Glass on the left old filter water, glass on the right new filtered water. Without send ending the water to a laboratory for testing i cant say 100% whats been cleaned out. But the orange specs i think is iorn and the black filter who knows but there is a difference with using filters.
