Review on Cartridges 17 Stage Upgraded WeGuard Universal by Gary Beard

So I had an Aqua Earth 15 stage that I've been using for a few months and I decided to try other brands to see if I got something or a felt difference. Here's the kicker, both cases look exactly the same except for the filter inside. I removed the old unit and installed the new one, turned on the water and waited for the sooty water to filter out. Then I installed the shower head and decided to take a quick shower. The filter seems to work fine, as does the Aqua Earth, but the only difference is the housing, it was leaking. I removed it and reinstalled it with new teflon tape but the leak was still coming out of the case. I had the idea of taking the filter out and putting it in the Aqua Earth case and it worked exactly as intended. So I mostly use Aqua Earth with this 17 stop filter. It would probably be cheaper for me to buy a replacement filter than to buy the whole unit. 1 star for the body and looks like I don't have the oldest Aqua Earth block, this block is quite defective. Assembly. I bought two, the other was actually for my other shower, but I think I'll install the extra filter that came with it (supplied 2, one inside and one spare) on the Aqua Ground and return the 2nd unit to the seller.
