Yes, I do notice that now. It seems impossible that so much water pressure can come out of it if the water comes up and around the cartridge and not through it but it does.
Still no improvement on hair or scalp though.

A slightly acidic water is best for the skin.
Lower ph

It does need hole in the bottom
It runs mixes from the top using the propeller….
Water comes in from the top and out the sides
If there was a hole in the bottom the vitaminc would all run out

you will notice over time the vitamin c is being used up

Thanks for the info Mary. Checked out their site and compared to what I could find in the U.S., Aquasmart seems superior.

Canada also has ShowerPure, and it seems comparable to the Aquasmart filters. However, Aquasmart says their filter does not impact water pressure, so I’ll try that one first.

Rosey Glow,
I do not have a shower filter (looking for one), and was tired of putting on lotion with a lot of additives after I shower, so I put almond oil on my skin instead. It is food grade and I found it at my local health food store. I wanted to re-assure you that apart from being cheap and lasting forever because you don’t need to use much, it is not greasy at all, and I can actually use it on my face without breaking out or being as shiny as I used to be with other “facial” moisturizers, even the “oil free” and organic ones. (I used to have a lot of issues with acne). I think using Dr. Bronner’s peppermint soap on my face also helps with the clear skin.

Go for the oil for your dry skin! You won’t regret it 🙂

yes I agree I have done hours of research and the whole hydrochloric acid thing seems to be over exaggerated, on multiple sites it suggest it is safe and is even used for dialysis patients in hospitals, it even explains it on the sonaki website in the faq’s how we even have hydrochloric acid in our own bodies, however my opinion is to use a metal removal filter in conjunction with a secondary vitamin c filter because heavy metals are leaching into our water supplies as well, especially with introduction of chloramines, it seems to degrade metals significantly faster. My choice would be sonaki because it looks better and one can clearly see when its time to change it, but to check when it is time to change any other vitamin c filter all one needs to to do is go to your nearest pool supply store or home depot and buy chlorine/chloramine test strips or drops.

It lowers the shower head by about 2 and 1/2 inches and you can attached a handheld to it. It is great!
