The directions on the website were sparse. The part numbers in the manual didn’t match the part numbers on the website. All I need to filter is arsenic, my tap water is from aquifers and is pretty good otherwise, no sediment, rust, or other chemicals. So, I just bought three arsenic filters.
Don’t really need the arsenic filters, the water is just under the standard 10 pbb, but I figured why not? When the filter was new, I paid for a water test of before and after the filter. Before was 8.(something) and after was 0.5ish. So, it made a big difference.
No amount of arsenic is safe, like no amount of alcohol. Same idea, but with water. I’m sure arsenic, even at 8, won’t be the thing that kills me, but again, why not filter it since I can?
I have an under the sink RO system under my sink also. The filters are expensive and are capable of only a slow output. They do work and make my tea taste better.
But I live in a very rural area and need to have my own well. The water is potable as is. But does suffer from extremely high iron and calcium levels. So it’s hard on those filters. They only last half as long as they are supposed to.
