**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.

Thanks,

iSpring Water Systems, LLC

**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.

### ⭐⭐⭐⭐⭐ Thanks Nick!
*by M***A on September 1, 2025*

Hi Guys:) 🤗 Nitrates in my well water, 😩. Have been using the I spring 6 stage R.O. system for the past 2 years. Really happy with the functionality of this unit. Recently, I got a positive test result for bacteria.... right after I replaced all new filters. I called customer support and spoke to Nick. So helpful and accommodating. Nick offered a resolution and support. Customer service is the key to any product. I am leaning towards purchasing another I spring 6 stage unit instead of sanitizing my current unit, and getting a different plumber to install it. Thanks again to Nick, for all your assistance. Way to go customer service!!!
