What this under sink system takes on
- Filtering happens on demand at the tap you choose
- Remineralizer adds back calcium and magnesium
- Best for daily drinking and cooking water
If your household drinks from the tap or fills a pitcher every day, the Aquasana SmartFlow works under the counter to filter water at the source. It is certified to meet several NSF/ANSI drinking water standards and reduces up to 99.99% of contaminants, among them lead, fluoride, PFAS, microplastics and pharmaceuticals. That range is useful when you want one system to handle both everyday chlorine taste and longer term concerns about what's in your water.
We'd consider this a strong fit if you already refill water bottles at home or are tired of hauling cases from the store. Each filter set replaces the equivalent of 2,750 or more plastic bottles, according to Aquasana. The remineralizer restores calcium and magnesium after filtration, which sets it apart from standard RO setups that strip minerals and can leave water tasting flat.
This is a plumbed appliance, not a countertop filter. It needs an under sink footprint and a faucet cutout.
What $214.99 gets you today
At $214.99, this sits $15.50 under the typical price over the last 90 days. That basis matters because it reflects what shoppers have actually paid recently, not a padded list figure, so the discount is modest but real.
The box includes your first filter set, the RO membrane, a storage tank, the faucet and the parts for under counter installation. Replacement filters are the ongoing cost to plan for, so check current cartridge pricing for the model before you commit. Long filter life is one of the claimed benefits of the SmartFlow design.

Fitting it under your sink and keeping it running
Measure the cabinet before you order. You need room for the tank and the filtration unit, plus clearance around your existing plumbing. The brushed nickel faucet matches most kitchen hardware.
Aquasana recommends professional installation, and the included parts are meant for under countertop setups. If you rent or your landlord limits plumbing changes, confirm that first. Cartridge swaps are a twist out, twist in job once the system is in place, which keeps routine care simple.
When this system is not the right call
Skip it if you need cold, filtered water instantly without a tank, since this design stores treated water before it reaches the faucet. A tankless RO or a pitcher filter may suit a smaller kitchen better.
It is also the wrong fit if you are not ready to plumb a dedicated faucet and commit to buying Aquasana cartridges on their schedule. If your main goal is removing chlorine taste from shower water, a whole home or shower filter is the more direct answer.
