Review on 🚿 Revitalize Your Shower: UBS Vitamin C Cartridge - 5 Pc Pack for Vita-fresh Shower Filter, 8.82 Ounce by Robin Brinks

They are definitely not as good as the 3 cartridges that come with the original shower filter. (amazonDOTcom/gp/product/B00KAMG0S/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1) I'm just in my house and I take a quick 10-minute shower and use a water-saving shower head that allows me to turn off the water with just a trickle while I do it the shower. The original 3 filters lasted me 5 months before I needed replacement filters. It took a few showers before I saw the contents of the original filters begin to dissipate; as if there was a lot of vitamin C in each filter. I ordered this 5-pack in February of this year (2018) and it is already the 5th cartridge. When you shower for the first time, you will immediately see how the contents of the replacement filter are already decomposing and dissolving. This shouldn't happen unless the water is constantly flowing during the 10 minutes I'm in the shower. These replacement filters only last 3 weeks. Of course, they aren't made in the USA, so I don't expect a lot of quality control. Where is the integrity of the companies? I hope I can find a better shower filter.
