Review on 🚿 AquaHomeGroup 20 Stage Shower Filter with Vitamin C E: Ultimate Solution for Hard Water Treatment - High Output Shower Water Filter to Eliminate Chlorine and Fluoride - Includes 5 Cartridges for Long-lasting Effectiveness - Ensures Consistent Water Flow with Showerhead Filter by Dustin Miller

We have been using shower filters for many years. We currently have a 12-level filter. Originally the cartridge was 18-gauge, but there are no similar refills. That is the situation with this product. Revain sells the device with 5 cartridges. I haven't seen 20 gang gas stations for sale. Hopefully they'll be available before the bundled ones run out. The water flow is similar to other filters we have used. This product doesn't slow down the flow significantly even after being in the shower for a while. To be fair, this is also true of the earlier versions we've used. The product claims to do the job better and soften the water as well. Whether that's true, I can't say yet. We get water stains on the glass shower door. Time will tell if they go away with this filter. The product is expensive. Works well and nicely packaged. Will be a good housewarming gift.
