    • Absolute no-brainer for newborn or individuals with skin problems.
Style: Pack of 1
10/10. If you have a new baby, this is what you want. Can vouch personally with own baby. Did all the research and personally put to the test with newborn (from first bath to still using @9mo now). Skin has been so much better. Reduced dryness. I use one personally as well when taking occasional bath. Not only does the water feel softer, can smell also the difference in the chlorine in the city water when not using. This is the product you want to trust me. ... show more

    • Peace of mind at bath time
Style: Pack of 2
Great filters that give me peace of mind when bathing my kids. When someone recommended I look into the contaminants in the water where I live I had no idea how extensive the list would be. I knew I needed to do something immediately. I ordered a shower filter and bath filters immediately. The most noticeable improvement the chlorine smell disappeared but then i started noticing our skin wasn’t so dry and our hair felt better. If you aren’t already filtering your water, you need to start now, epecially if you have kids. Our skin is our biggest organ and we’re already exposed to so many toxins, I feel we should limit the exposure where we can. I will definitely be buying more when I run out. ... show more

    • Why you won’t regret buying these
Style: Pack of 1
The filters are easy to install (I had a little bit of a hard time unscrewing the bath ball because the filters last so long, the bath ball stayed closed for a while) Filters seem to work great, last a long time, and reduce the chlorine smell in water! The value is definitely worth the cost.

    • Eczema
Style: Pack of 1
This has really helped with my daughter’s eczema! I haven’t done any tests on the water but I believe it works. This is my second one and I will be buying a third soon

    • Low bath ball volume
Style: Pack of 1
As others have noted, the replacement cartridge does not have as many bath balls as the original cartridge which is disappointing. That being said, I will probably buy again in the future because I live in an area with very hard, heavily chlorinated water and cannot install a whole-house filter. Even with less bath balls in the cartridge, this definitely helps improve the water quality. ... show more

    • who knew filtered water made a difference?
Style: Pack of 1
This is my second purchase. There is a big difference in the health of my hair and seemed to help preserve color treated hair. My son has eczema and I am not sure if it made a difference in his skin but it definitely did not hurt it. Such a simple solution if you feel like your hair or skin is affected by the tap water in your area. I also bought a filter for the shower as well. ... show more
