What to Consider before Buying the Aquasana AQ 5300 3 Stage Water Filter

Filters and Pollutants Removed

AQ 5300 filters - ACWThis Aquasana under sink water filter integrates three (3) different filtration stages to maximize the pollutants reduction process. This includes:

  • Pre-Filter.
  • Activated Carbon.
  • Catalytic Carbon (Ion Exchange).

The filtration process is as follow:

  1. The first filtration stage is the pre-filter; this is the most important stage as it will remove any dust, rust or particle that can clog the next filters.
  2. Pharmaceutical residues, herbicides, PFOS and PFOAS (a contaminant that is present in fire fighting foams), pesticides, semi-volatile and volatile organic compound and MTBE are removed over the second stage, where the Activated Carbon Filter is located.
  3. Finally, the Aquasana 3 stage Max Flow has a 0.5 sub-micron filter for tiny particles like asbestos or bacteria that may sneak through the chemical filters; it also includes an ion-exchange process that removes heavy metals like lead and mercury.

Operation & Maintenance

Maintenance is also easy. The filter covers screw off and on, and the filters themselves slide on. Changing these filters only takes a couple minutes.

Keep in mind that you will need to ensure a minimum water pressure of 20 PSI and maximum of 80 PSI; this will translate into a flow rate of 0.5 gallons per minute.

A pressure over 80 psi will make your system to leak.

Based on the manufacturer specifications, the filters can last up to six (6) months with a filter capacity of 600 gallons. This time frame will also depend on how much you use the system and the level of “contamination” of your water.

Lastly, check with the supplier (Aquasana preferably) about a possible lifetime warranty over the filters. They have a subscription program where you can receive filters and o-rings overtime (we think, this could be a good think considering that the o-rings could be a problem in the future).


Aquasana AQ 5300+: An Upgraded USWF version

Aquasana AQ 5300+ 3-Stage Max Flow Under sink water filter reviewAquasana has taken the next step and launched the Aquasana AQ5300+. The main changes for the latest under sink water filter is:

  • 800 gallons filtering capacity.
  • 0.72 gallons per minute flow rate and,
  • Comes with Bluetooth connectivity.

There’s also a smartphone app that alerts you when the filters need changing, which is a nice touch.

…..the downside:

Even though, the Bluetooth feature is a great advantage, it is not as great as expected. This connectivity system is capable of telling when the filters need changing only if you indicate the location of the filter and the date and time you installed them all; this means that the app will calculate the lifespan of the filters only by knowing the date and time of installation.


Aquasana AQ 5300: Final Thoughts

With a 0.5 gallons per minute flow rate and a 600 gallons capacity, the filtration system will ensure that you will have clean water anytime you require it.
