Question: Is there a trick to unscrewing the 2 halves to replace the filter (mine seems to be stuck solid!)?
Document: It has now been almost 3 months since the replacement was installed and my hair is sticky once again. This is becoming expensive, to have to replace the filter every 2-3months. It works great when new, and I could understand if it lasted 6 months plus when the claim is really 12 months... but 2-3 months? !
Bad News:Leaked where the two halves screw together. Had to take it to an ACE Hardware store & get a rubber O-Ring to fit. Leak stopped, water pressure went back to normal. Housing cracked after about 2 years. Had to buy another Sprite HOC unit. Different model this time, fits same HOC filter.Good News:Every other claim made by this company is true & it works. I have psoriasis & it helps immensely.
This filter seems to do what it says. I live close to a water tower. When the chlorine is low at the end of the line. They pump up the volume. I truly believe it's working. Cause my shower don't smell like a swimming pool anymore. My hair is softer and so is my skin.I would recommend this product. Hope this review helps someone decide on a their purchase. Cause the reviews of this product helped with mine. There is a plus to this review.
.I bought this to clean up the water from my new irrigation well, so that washing my car wouldn't leave noticeable dried water spots. To that end I also bought a brass reduction fitting to go from 3/4" to 1/2" pipe threads. All for naught. Water pressure from the well pump seems to be low, so it had a difficult time overcoming the reduction in flow caused by the filter. A weak stream of water makes it hard to wash a car.
Just got 2 of these filters last night and popped them into both showers. One worked perfectly, tight as a drum. The other one leaked from the housing itself. We even tried plumber's tape on the housing threads, but nothing. Checked to see that the O-rings were seated properly, but still leaks. lol Looks like a defect in the plastic itself that connects the two halves.Update: Happy to report that we sent that one back and got another one.
I installed this on a European style detachable shower head and it fit perfectly. I attached directly to where the hose meets the faucet instead than to the shower head itself since the weight may just take it down from the holder. Overall so far I can't really tell a noticeable difference on the quality of the water. However, the item seems very well built and solid.
The one problem was water leaking out where the two halves of the filter screw together. It had the appearance of having a place to put a small rubber O-Ring in there & then screw the two halves together, but it did not come with one, nor did the instructions & diagrams show any such thing. Anyway, I took ours to the hardware store & got a rubber O-Ring for this. It worked 100%.
Have used more expensive shower filters and this one seems to perform just as well with the same results. Skin and hair feel better (we live in an area with very hard water) and the price is about 1/3 of what I paid for my original shower filter system.
After cleaning everything out and re-lubricating the rings I put it back together and there were no further leaks. I just wanted to throw this out there in case anyone has leak issues - I know this is pretty obvious to most people. Other than that the filter seems to work great so far.
Instead, I know it needs replacement when my body starts itching again. I replace the filter and the itchiness goes away completely within a few days. You can't argue with results.
Answer: yes
