When residential water systems first appeared, the market was taken over by reverse osmosis systems, despite the fact that there were also other types of water filters out there. Nevertheless, the reverse osmosis models eliminated most contaminants, which is why they were considered to be the most efficient. For those of you who are unfamiliar with these types of filters, you should know that they feature a very dense membrane which practically filters all contaminants. It sounds very good in theory right? However, reverse osmosis systems had one major problem which eventually caused their downfall: along with the bad contaminants, they also filtered the good minerals. Over the years, other types of filtration systems got better and better until they became just as or even more efficient than the reverse osmosis systems. Furthermore, RO systems even started having a bad reputation due to the fact that they striped the water of all its nutrients. Nevertheless, everything changed with the launch of the Aquasana OptimH2O Reverse Osmosis + Claryum Water Filter. This is probably the most efficient water filtration solution available on the market at the moment. In what follows, you will see exactly what makes this filter so unique.

Design

When it comes to under counter water filters, design is not the most important aspect to consider. Given the fact that these systems are out of sight, their design can’t affect your kitchen’s interior. However, if you have a small kitchen and you also use the space under the sink for storing dishes or cleaning products, you might be looking for a compact water filter which takes little space. If that is the case, we have to say that the Aquasana OptimH2O Reverse Osmosis + Claryum Water Filter is not the most compact under sink filter. Due to the way in which it is designed to function, this water filter features a rather voluminous tank which is unlikely to leave you with any free under sink space. However, as you will see from this unit’s performance features, we think that this is a sacrifice worth making. The filter itself has the following dimensions: 12″ × 4.5″ × 12.5″ (L × W × H). However, you must also consider the tank which is 16 inches tall and has an 11 inch diameter.

Features

Aquasana OptimH2O Reverse Osmosis + Claryum Water Filter takes the best out of the most efficient filtration systems. Overall, this system is certified by the NSf to remove over 74 water contaminants. So far, that is the most impressive performance that we have ever encountered in any water filtration system, not just the under sink models. The unit is also very easy to use. The replacement filters are designed in order to be replaced within a matter of seconds by simply twisting off the Claryum filter housing and replacing them with new ones. We also like the fact that this filter has an impressively fast flow rate which delivers an optimally clean water at 0,8 gallons per minute.

Performance

As we already mentioned, this water filter removes up to 74 water contaminants. This is quite an impressive performance, even for Aquasana as most of their products remove up to 60 contaminants. As such, you might be wondering how this water filter works in order to remove so many contaminants, without also removing the beneficial minerals. Well, for starters, the filter uses a filtering membrane with an above the average density which filters all dissolved solids, even the ones smaller than a micron such as arsenic or fluoride. After being forced through the reverse osmosis membrane, the water is exposed to activated carbon which reduces organic chemicals like VOCs, MTBE, pesticides and herbicides. The next step in the filtration process is the exposure to catalytic carbon which targets chlorine and chloramine. Chlorine and chloramine are normal in tap water because they are used as disinfectants by local water purifying authorities. Nevertheless, this doesn’t mean that they are safe to incest. Chloramine is particularly dangerous as it is a potent respiratory irritant which can lead to severe respiratory problems. After the water is exposed to the catalytic carbon, the ion exchange filters trap its heavy minerals (mercury or lead). The last step of the filtration process is the absolute sub-micron filtration which captures the tiniest of contaminants, even the chlorine resistant cysts like Cryptosporidium or Giardia. After the filtration process is complete, the water goes through a re-mineralization process which puts back the healthy minerals into the water in order to improve the water’s pH balance and alkalinity. As such, this filter manages to remove over 95% of fluoride, over 97% of arsenic, over 99% of lead and asbestos as well as over 70 water contaminants without delivering flat, de-mineralized water.

Other considerations

The overall filter is covered by a 2 year warranty. There are also some separate part warranties that cover the RO membrane for two years, the Claryum filter for 6 months. and the remineralized for one year. In order to convince its customers of its efficiency, this filter comes with a 90 day guarantee. The filter’s capacity can vary depending on usage and water quality. On an average, you shouldn’t have to replace the filter cartridges more often than twice per year.  Last but not least, this water filter can be acquired for $349.99, an impressive price if you consider the fact that this is the most efficient under sink water filter on the market. This price also includes a 1-year capacity remineralizer.
