The Aquasana AQ-5300+ also known as 5300 Max Flow is much similar to the Aquasana AQ-5300 model but with a slightly larger capacity and faster flow rate.

However, the two models feature 3 filtration stages rather than the 2-stage process of the AQ-5200 model. In other words, the AQ-5300+ is a robust and super effective system as you are going to see below.
Like the AQ-5200 above, the Aquasana AQ-5300+ model utilizes Claryum filtration technology but with an additional stage to make it a 3-stage filtration system.
Stage 1 of the system is fitted with a 20-micron sediment pre-filter which traps silt, dirt, rust and other visible sediments to prevent the following stages from clogging too quickly.
It’s a feature that often misses in most under sink water filters yet it’s really essential particularly in areas where the sediment and silt levels in the water are higher than normal.
Stage 2 and 3 consist of Aquasana’s Claryum filtration technology which is made up of activated carbon filter, catalytic carbon filter, ion exchange, and sub-micron filter.
At first, the water flows through the granular activated carbon filter where a significant amount of both organic and inorganic chemical contaminants that include chlorine herbicides, pesticides, pharmaceuticals and VOCs are removed from it along with unpleasant tastes and odor caused by these chemicals.
From there, the water goes through the catalytic carbon filtration media which is a more powerful carbon filter that clears out 99% of the chlorine and remaining chemical contaminants in the water. It also totally reduces chloramine present in the water, something that most under sink water filters cannot.
After that, the water passes through an Ion exchange filter which features a series of resin beads with large surface area and they work effectively to extract heavy metals like mercury and lead plus other micropollutants that the carbon filters fail to catch.
At the last stage of the filtration process which is the 3rd stage, we have the sub-micron filter which clears out the remaining particles and contaminants from the water down to 0.35 microns. It will capture asbestos, chlorine-resistant cysts like cryptosporidium and giardia, and any other impurities that the earlier two stages couldn’t remove.
These three stages together will eliminate up to 99% of 77 different kinds of contaminants but leave behind healthy minerals to give you a clean, fresh and natural-tasting water.
They will also not remove other total dissolved solids (TDS) and the only microbes they can remove are cysts hence it’s not that effective for bacterial removal which simply means you should only use the unit to filter treated water that’s microbiologically safe. It’s certainly not recommended for use with well water which doesn’t contain chlorine for disinfection.
Capacity and Efficiency
While the AQ-5200 has a filtration capacity of 500 gallons and the AQ-5300 600 gallon, this AQ-5300+ model offers up to 800 gallons before a change of filters is needed.
This slight improvement in the total amount of water it can process is mainly brought about by the larger cartridges it uses and it will allow you to utilize the unit for up to 6 to 8 months before replacing the filters.
The flow rate is equally a bit faster than that of the previous two models. They delivered not more than 0.5 gallons per minute yet the AQ-5300+ provides 0.72 GPM which is not much change but it’s significant enough to ensure you get slightly faster water flow from the faucet.
Installation and Maintenance
Hooking up this Aquasana unit should not pose a problem if you have some basic DIY skills. The installation manual explains the entire process step by step and all the necessary parts are included with the first set of filters already installed in the system.
It won’t take more than an hour to set it up but like the AQ-5200, it comes with its own dedicated faucet that you need to install, so some drilling might be involved.
No much maintenance is required other than occasionally changing the filters at least after every 6 months and cleaning the exterior of the unit.
Another good thing is that this system too comes with a battery-operated alarm/indicator which will beep an audible alert and flash red to remind you when filter replacement is needed.
You can even link the system to your phone via Bluetooth to receive the alerts on your phone. There’s an app from the manufacturer that you can download and install for free, and keep track of the number of gallons of water have been processed.
Unfortunately, this app is only available for iOS devices. The indicator also uses a battery that will require changing with every filter replacement which translates to some additional costs although not very much to cause concern.
From all these wonderful features to the high filtration performance, it’s safe to say that the Aquasana AQ-5300+ is an under sink water filter that’s worth every penny.
For those that prefer Aquasana products and the AQ-5200 model didn’t win them over, this is an alternative you might want to check out.
