SimPure Y9A
300 GPD · 6-Stage · UV + ALK Remineralization · NSF/ANSI 58
SimPure's most complete countertop RO — UV and remineralization standard, $20 less than the Y7P-BW
The Y9A has everything most countertop RO buyers want: UV sterilization, alkaline remineralization, 300 GPD production, NSF/ANSI 58 certification, and a perfect 5.0 rating. It costs $20 less than the Y7P-BW and adds the remineralization stage the Y7P-BW doesn't include. The Y7P-BW is more water-efficient (4:1 vs 2.5:1 waste ratio) and has far more reviews. For most buyers the Y9A is the better buy — unless water conservation is a specific priority.
The 6 filtration stages
Pre-filter carbon — removes chlorine, sediment, taste/odor before the membrane. Protects membrane life.
RO membrane, 300 GPD — removes dissolved solids, heavy metals, fluoride, nitrates, PFAS, lead, arsenic. NSF/ANSI 58 certified, SGS test report available.
UV sterilization — 99.99% elimination of bacteria, viruses, and protozoa. Runs after RO filtration. Indicator on control panel shows UV filter status.
Alkaline remineralization — pre-installed — adds calcium and magnesium back into RO-filtered water, raises pH to produce pH-balanced mineral-rich water. This is what the "pH+" label on the tank refers to. Comes pre-installed, not an optional add-on.
Y9A vs Y9T — which variant
Y9A — Remineralized Water (recommended)
ALK remineralization stage included. pH-balanced, mineral-rich output. Better taste for drinking, coffee, and tea.
Y9T — Nearly 0 TDS Water
No remineralization. Nearly pure RO output. Choose for aquariums, laboratory use, steam irons, or any application requiring the lowest possible TDS.

Questions
Yes. The control panel shows UV as a distinct stage indicator alongside PPC, RO, and ALK. UV runs after RO filtration and before the alkaline remineralization stage.
Y9A (Remineralized Water) for better-tasting mineral-balanced drinking water — this is the right choice for most buyers. Y9T (Nearly 0 TDS) if you specifically need nearly pure output for aquariums, laboratories, or low-TDS applications.
The Y9A costs $20 less, adds alkaline remineralization the Y7P-BW lacks, and produces 300 GPD vs 100 GPD — three times faster. The Y7P-BW is more water-efficient (4:1 vs 2.5:1 ratio) and has more reviews (1,240 vs 130). For most buyers the Y9A is the better buy. Choose Y7P-BW if water conservation is a priority or you want the more established product.
No. Countertop only — fill the side feed tank manually, plug in, and run the initial flush. CF, RO, and ALK filters come pre-installed. Setup is about 10 minutes.
Bottom line
$349.99 with UV, remineralization, 300 GPD, NSF/ANSI 58 certification, and a perfect 5.0 rating. The Y9A does more than the Y7P-BW for $20 less. If you've been comparing SimPure's lineup or looking at the Waterdrop K19-SFK, the Y9A deserves to be in that comparison — it's now SimPure's strongest countertop offer.
