The Aquasana AQ-5200 is amongst the top performing under sink water filter systems on the market and the main reason behind this is the fact it’s one of the few models that have the most contaminant certifications. Here is an outlook of its major highlights and setbacks.

Filtration Performance

The AQ-5200 utilizes Aquasana’s panted and NSF certified Claryum filtration technology which is a 2-stage high-performance filtration process designed to remove over 60 common water contaminants.

In fact, it’s only a tiny handful of filters on the market that use this filtration technology which consists of activated carbon media, a catalytic carbon filter media, and ion exchange.

The activated carbon filtration adsorbs organic chemicals in the water such as VOCs, MTB, herbicides, and pesticides as well as pharmaceuticals like ibuprofen and estrone.

From there, the water goes through a catalytic carbon filter where it isolates and eliminates chlorine and chloramines thereby improving the taste and color of the water.

The next filtration phase involves an Ion exchange which takes care of the heavy metals like mercury, lead, and arsenic. The system is also equipped with absolute sub-micron mechanical filtration (ASMF) which helps capture asbestos plus chlorine-resistant cysts such as giardia and cryptosporidium.

The use of these different filtration technologies significantly enhances the unit’s performance compared to its competitors allowing it to remove over 97% of the contaminants in the water.

In addition to this, the AQ-5200 is certified as well to remove PFPA and PFOS, and the filtration process itself is selective hence retains the naturally beneficial minerals resulting in filtered water that’s cleaner, healthy and tastes great.

Capacity and Efficiency

Filtration capacity is the area that the Aquasana AQ-5200 slightly falls short because it’s only capable of processing up to 500 gallons of water before requiring changing.

This is the lowest capacity on our list, but if you use the filter to process around 2 to 3 gallons every day, it will likely last up to 6 months which fairly good.

Water flow rate is another area that this unit doesn’t really do well in as it can deliver just 0.5 gallons per minute. This only translates to a 25% increase in the flow rate compared to normal tap and as such, you may experience a slightly slow pour but the unit is efficient.

No water is wasted and the unit can handle a maximum working pressure of 80 psi and a minimum working pressure of 20 psi.

Installation and Maintenance

You will need no plumber to set up this AQ-5200 system if you are a handy person because it’s designed for easy DIY installation with everything you require to get the job done included in the package. It comes with a separate dedicated faucet, so you will have to do some drilling if you don’t already have an extra mounting hole drilled into your sink.

Changing the filters is a snap too. No disconnecting hoses or water lines. All it takes is a simple twist to unscrew the filter housing, remove the old cartridge and insert the new one.

You only toss the filter cartridge and keep the housing which makes the replacement a bit less costly considering that the filter lasts up to 6 months.

The amazing thing about this Aquasana unit is that it’s fitted with a performance indicator which is a smart-tech system that will show the efficiency of the filter and notify you when the filter requires to be changed.

Therefore, no need to keep checking or guessing when to replace the old filters which is a big plus in terms of ensuring the system remains effective throughout in filtering out contaminants.

To sum it all, while the capacity and flow rate are on the lower end, the AQ-5200 is a solid under sink water filter system with a reliable filtration technology.

The low capacity may be a deal-breaker for some but if your regular water usage is not that high and you want a unit with great filtration power that will deliver healthy clean water, then this is an option you can absolutely consider.
