What this under sink filter handles
- Runs a dedicated drinking-water tap for cooking, bottles, and refills.
- WQA tested against a broad contaminant list, with healthy minerals left in.
- Will not reduce total dissolved solids, so check your water goals first.
We'd consider this Aquasana if you want filtered water from its own tap for cooking, bottles, and daily drinking. The three-stage Claryum design is WQA tested, and Aquasana says it cuts a long list of contaminants that includes chlorine, lead, PFAS, and microplastics, while the minerals stay in your water.
It delivers 0.72 gallons per minute, so filling a pot or bottle involves less waiting than a drip pitcher. Your kit includes the first filter set and the faucet, along with the parts for under-counter installation, and Aquasana designs the setup for DIY. Measure your cabinet first, since the system wants 15.85 inches of height plus clearance.
What the $199.99 price reflects
At $199.99, this system sits $15.82 below the $215.81 typical price over the last 90 days, a 7 percent difference. That's a modest gap, so our advice is to compare the price against the ongoing filter cost and your household's actual water use, not the discount alone.
Aquasana puts running cost below 10 cents per gallon and says a filter set lasts six months or 800 gallons, whichever comes first. Your real spend depends on how much you drink and cook with it, so work out a replacement rhythm that fits your kitchen.

Room fit, replacements, and daily upkeep
Under-sink space drives the decision. The 15.85 inches of height covers the system itself, so leave clearance above and around it and check that a disposal or pipe run won't crowd the cabinet. If your sink base is tight, measure before ordering rather than after.
Filter changes are a twist-off job with certified replacements, which keeps the same contaminant coverage going. The set stands in for thousands of single-use bottles, so decide how often you'll reorder and whether that fits your routine. Before you commit, confirm your faucet setup accepts the included tap and that you're comfortable with the filter schedule.
When this system is the wrong fit
Skip it if lowering total dissolved solids is your goal. This Aquasana leaves healthy minerals in and doesn't touch TDS, so it won't deliver the reading a reverse osmosis unit would. For that job, look at a different type of system.
Also pass if you can't spare the vertical cabinet room or would rather keep things simple with a pitcher. Ask Aquasana support about your faucet and cabinet setup before ordering if either is unusual.
