The vast majority of household point-of-use drinking water systems are designed for water that has already been treated initially with either chlorine or chloramines (as well as fluoride) by the municipality, to make it microbiologically safe by killing bacteria and viruses – with these systems’ own filters going on to remove things like residual sediments, tastes, odours, and the added chlorine, chloramines, and fluoride, themselves.
If you’re starting with untreated water to begin with (if it comes from a lake, river, or even some wells, where human or animal waste may enter the water), those systems will not suffice: the water would still need to be boiled, distilled, or sanitized with Ultraviolet light to safeguard against pathogenic bacteria, viruses and parasites (such as protozoa and helminths) and waterborne diseases such as diarrhoea, cholera, dysentery, and typhoid.
But what if you do have a municipally treated water supply, but your local water treatment plant stops operating properly or there’s a water main break en route (which may take some time before that’s discovered and the word gets out to you)? Or what if you suspect that treated water might get contaminated again on the long route from there to your kitchen tap – could there be some sort of backstop for that?
There is: a final Nanofiltration membrane filter, which has pore sizes of just 0.01 microns in diameter to let the water flow through, which can capture both bacteria (which range between 1 to 10 microns in length and from 0.2 to 1 micron in width) and pathogenic viruses (which range from about 0.02 to 0.5 microns in size) which do not fit through those pores. Although it should not be relied indefinitely if there is a water boil advisory issued in your region (you should still heed that warning or combine this with a UV-sterilization unit), it will most likely protect your household from getting sick if you don’t find out about it right away.
The OPUS NANO-2024 produces great tasting water that is free of fluoride, chlorine, lead, heavy metals, MTBE, VOCs and contaminants, while maintaining pH (alkalinity) and dissolved minerals. The system features two activated carbon (granulated and advanced carbon block) filters, one catalytic carbon block chloramines filter, bone char fluoride filtration, as well as 0.5 micron micro-filtration technology that removes 99.5% of mercury, lead, and giardia, cryptosporidium, entamoeba, and toxoplasma cysts, to ensure contaminant-free water.
A special feature of this system is its final .01 micron nanofiltration filter, which blocks protozoa (cryptosporidium, giardia), bacteria (campylobacter, salmonella, shigella, E. coli), viruses (enteric, hepatitis A, norovirus, rotavirus), and 85% of tested pharmaceutical drugs (which sometimes make their way into a water supply via sewage).
The OPUS NANO-2024 uses five advanced filtration components to provide seven filtration stages, using three 10″ vertical filters and two horizontally mounted inline filters. Tubing, a designer faucet, a John Guest quick connect for the faucet and a John Guest type ball valve to allow easy water shut off for filter flushing and future filter changes are all included.
Included Components:
1. Triple filter wall mount housing that can be installed under a sink or in a basement with the 5 micron carbon block sediment filter (Stage 1) and nanofiltration filter (Stage 7) horizontally mounted on the metal frame.
2. Inline horizontally mounted 5 micron carbon block sediment filter (Stage 1).
3. 10″ bone char fluoride adsorption filter (Stage 2).
4. 10″ 1 Micron Catalytic Carbon Chloramines Filter (Stage 3 & 4).
5. 10″ 0.5 micron carbon block microfiltration filter that removes MTBE, VOCs and chlorine, with up to 99.5% removal of lead and mercury (Stage 5 & 6).
6. Inline horizontally mounted nanofiltration filter (Stage 7).
7. Brushed nickel lead-free ceramic disk designer faucet with normal sink installation components, including a John Guest quick connect that is screwed onto the end of the faucet for fast and easy connection of the blue tubing from the output of the system.
8. Quick connects throughout for all ¼” tubing connections, including on the beautiful brushed nickel ceramic disk designer faucet.
9. Two 5 foot lengths of flexible LLDPE ¼” BPA free tubing.
10. John Guest ball valve shut-off valve, to make it easy to shut off water to the system for initial filter flushing and future filter changes, connected to the water input of the horizontally mounted 5 micron sediment filter. A filter wrench is included to enable easy opening of the filter housings for filter changes.
