Fresca Disruptor is among the few filters that can get rid of bacteria and is among very and very few non RO systems that can filter out viruses.
This is a set of replacement cartridges, all 3 stages.
Stage 1 is pleated polyester sediment filter at 5 micron nominal. This stage is there to mainly protect the next 2 stages of any sediment. It will cut off anything above 5 micron: dirt, dust, rust, stones, sand etc etc.
Stage 2 is a core of the system, stage that does all the heavy lifting. Made with new filter material from Ahlstrom (Finland). In short, it is electroadsorptive technology media able to remove or significantly reduces all of the contaminants on the list above except chlorine and taste/odor.
Stage 3 is high quality coconut activated carbon block. Since stage 2 takes out most of the bad things, what’s remaining is chlorine and so called “smell and taste”. 1 micron high flow carbon block clears it up giving the water a great taste.
