I used this to replace filters in my reverse osmosis system at home. The flow was so strong after the replacement that I was sure the filters weren't working, just water pouring out of the tap. So I bought a B073713G5F solute meter. The filter actually worked very well, reducing the dissolved solids from 60 mg/l to 5 mg/l! Another test showed that the water was much cleaner. So I highly recommend these filters as they work well and even better than the original filters.
