Question: does it come with a filter already in it or do i have to order one along with it?
Document: Had ordered a new shower filter. However, the product I received was clearly a used one- the packing was already open and the filter was dirty w/ scum inside. Trying to pass a used product as new.
Purchased this and installed easily within a few minutes, but when I turned on the water it leaked out the side spraying water everywhere. This filter does not come with a shower head as shown in the picture, you have to use your old one or buy a new one and screw it on to this unit, which for me was no problem as mine was basically new.
No tools required. It took about three minutes, to install it. I bought a new shower head for $6.00 ( it doesn't come with one) The difference in the filtered water, as opposed to city water, is fantastic.
I was worried with the comments about leak and such, but honestly, I feel like those people had a messed up faucet, or just flat out did it wrong.Does not come with a shower head, so make sure you have either a clean one, or (for us) a brand new one (from the hardware store)!
well,i'm pretty sure i would have liked it!i like the concept..however,i ordered a new one,paid for a new one & there is no doubt in my mind this vendor send a used or sent back item.so the vendor gets an F+ for trying to pull that over on me!i'll be calling credit card resolutions hotline and he will not be paid!this is awful!the filters come with paper seals,(and it had none at either end!
Bought 2. Installed the first one, turned on the water and it blew the shower head right off along with the plastic threads. Waited too long before I installed it so no warranty. The other one is sits unused, I'm sure its junk like the first. F -
Oh my water has started to smell bad again! That's because our filter is wearing out - and the difference is very noticeable! Time to re-order...
I found out it does not come with a shower head, it's just the filter. This filter attaches to any showerhead you put it with. So, you can use whatever showerhead you want with it.
I just feel a little drier than I did with the sprit. I also will have to order filters on line.But I think it was worth the switch to stop the leaks with the filter changes.
Very cheaply made. Already unusable. The threads wore out in a few months. Going back to Pur water filters,  worth the extra money. Last Pur filter lasted several years.
Answer: yes
