Applied Membranes cleaning cartridges are pre-filled with AMI’s specially formulated proprietary membrane cleaning chemicals for effective, fast and easy membrane cleaning. Simply exchange the pre-filter cartridge in your system with a new cleaning cartridge and run the system to flush the chemical into the membranes. Allow the solution to sit in the system overnight, then flush the chemicals to drain the next morning. We recommend a monthly cleaning to obtain optimum results.

AM-11 Acid RO membrane cleaner is specifically formulated to Calcium Carbonate, Mineral Scale, Hardness, Iron, Barium, Sulfate, and other scaling from RO membranes.

Carbonate scale fouling can be identified by the following symptoms:

  • The RO Membrane will likely exhibit low permeate flow
  • The RO Membrane will likely exhibit low salt rejection
  • The membrane may feel heavier than normal

I started seeing results after one and a half week!
A week and a half after starting this product, together with the serum, I started noticing a brighter and more even tone on my skin. And my sun spots started to fade. It worked for me... and really fast! To give you an idea of how uneven my skin was... when going out, my husband used to tell me to put on some face powder to even out the tone of my skin. Not anymore. I felt it was really gentle, and I have a very sensitive/rosacea prone skin. I combine both the night cream and the serum with my Vanicream skincare regime. I later added a niacinamide serum (I got that tip from Dr. Dray on Youtube) to boost the efficiency of the whole treatment. Be careful with the niacinamide though... some people cannot tolerate it. I think I could tolerate it because I already had my skin repaired with my Vanicream skincare regime. In conclusion, this product is worth every penny!

Great product, it works!
This moisturizer has help me a lot with my sunspots, I see the difference big time. I’m in my 3 bottle I think, and I also use their serum and night cream along with the face soap. Love this line of products and I’m coming from using Lancôme for years (my fave brand in so many products). I’d definitely recommend. I don’t find the creams smelling weird or with a sense at all (like some other people have said) and I have a K9 nose.

Simple but effective
I do like Eucerin products and this night cream is predictably smooth. I haven't noticed any miraculous change in my dark spots but I'm more interested in just keeping my skin soft. A little goes A LONG way so this bottle will last quite a while.

Great for Kids, Smells Nice, and No Harsh Chemicals
Size: 5 Ounce (Pack of 2)
This sunscreen spray is easy to apply, not greasy, and doesn’t leave a sticky residue. The tropical fruit scent is light and pleasant, which makes it easier to convince kids to wear it. I also like that Alba Botanica avoids oxybenzone and other harsh chemicals. It holds up well for swimming and outdoor play. The 2-pack is convenient to keep one at home and one in the beach bag. It is a great deal!
