The SimPure Y9A is a countertop reverse osmosis system for people who want a side refill tank and remineralized water. It needs no plumbing, but you should allow 18 in of vertical clearance and account for scheduled filter changes.
The Y9A uses 6-stage filtration, including reverse osmosis and a post-mineralization filter. Its transparent tank sits on the side, so you can check the water level and refill it without moving the unit away from a wall.
What stands out about the SimPure Y9A?
The SimPure Y9A’s main practical difference is its side-mounted refill tank. The mineral stage adds calcium, magnesium and potassium after reverse osmosis, so the finished water is intended to retain some mineral content.
SimPure Y9A UV Alkaline RO: Best for easy side refills
- 6-stage filtration
- Side-mounted refill tank
- Post-mineralization filter
- No plumbing required
A countertop RO unit with a visible, side-mounted tank and a post-mineralization filter. It suits buyers who want to refill without pulling the unit away from the wall.
Pros
- No plumbing required
- Side tank is visible and accessible
- Filter change indicator lights
- Removable drip tray included
Cons
- Needs 18 in vertical clearance
- Requires regular filter replacement
- Mineralization raises TDS after RO filtration
A side tank can simplify refilling when the system sits below a cabinet or against a backsplash. That advantage depends on keeping the tank-facing side clear, so measure the counter and nearby appliances before you choose a spot.
SimPure states a production rate of about 4.4 oz in 10 seconds under conditions of 60 psi and 77°F. The rate varies with inlet pressure and water temperature, so your kitchen may not match that figure.
Who is the SimPure Y9A best for?
The Y9A suits a household that wants countertop RO without plumbing and prefers an attached tank that is easy to see and reach. Its remineralization stage also fits people who prefer water with added minerals after RO filtration.
It can work in apartments, dorms, offices and small kitchens where an outlet and a suitable counter are available. SimPure also names RVs and travel setups, but moving use calls for careful attention to level placement, power and the unit’s storage instructions.
Skip it if you want a glass serving carafe, want near-zero TDS water, or cannot spare the required vertical clearance. The best countertop RO systems guide compares other layouts and priorities.
How should you judge Y9A filtration and remineralization?
The Y9A combines reverse osmosis with a post-mineralization filter. SimPure reports up to 99.88% TDS reduction before minerals are added back, and says the ALK stage can raise the final TDS.
SimPure names PFAS/PFOA/PFOS, lead, chlorine, nitrates and fluoride among the substances measured for reduction. It refers to SGS test results for detailed performance, so review those documents if a particular contaminant is central to your decision.
A TDS meter measures dissolved substances together; it does not identify which ones are present. A higher reading after the ALK filter is expected from remineralization and does not, by itself, show whether a specific contaminant is present.
The Y9A is not the right match if your goal is water with near-zero mineral content. For a clear explanation of how reverse osmosis changes mineral content, read whether countertop RO removes minerals.
Will the Y9A fit on your counter?
The Y9A measures 16 x 9.3 x 14.3 in and needs 18 in of vertical clearance. It uses a standard electrical outlet and does not need a plumbing connection.
Measure the counter depth and the gap between the worktop and upper cabinet. Leave room to remove the side tank, access the controls and handle the feed-water area.
Check the tank-facing side in its intended position. A wall, cabinet panel or another appliance can block the feature that makes refilling convenient.
The Y9A weighs 16.5 lb, so pick a stable place where it can remain set up. If you plan to move it between rooms or take it on a trip, make sure you can drain and handle it according to the manual.

What does daily use and maintenance involve?
Plan to replace the feed water daily and run the built-in flush monthly. SimPure recommends emptying the tank and draining the machine before an absence longer than a week.
PPC and ALK filters are recommended every 6 months, while the RO filter is recommended every 9 months. Indicator lights show when each filter needs replacement, although source-water quality and maintenance can affect filter life.
For an absence longer than 3 months, SimPure’s storage instructions call for draining and drying the unit, wrapping the RO filter in plastic and refrigerating it at 36–41°F. They also say to replace PPC and ALK filters before reuse.
Use the full manual procedure before storing the system. If you expect to be away often, consider whether this storage routine fits your household.
Some water remains because reverse osmosis sends concentrated impurities away from the membrane. SimPure says to replace that water with fresh feed water rather than reuse it.
How does the SimPure Y9A compare with AquaTru and Bluevua?
The best alternative depends on tank access, serving style and the documentation you want. The Y9A has a side tank and mineral stage, Bluevua comes with a glass carafe, and AquaTru emphasizes named IAPMO certifications.
| System | Standout detail | Container or tank | Filter details |
|---|---|---|---|
| SimPure Y9A UV Alkaline RO | Side tank and post-mineralization | Removable side tank | PPC/ALK every 6 months; RO every 9 months |
| AquaTru Classic Countertop RO | IAPMO certification to named NSF/ANSI standards | 2.7-liter dispenser | Filter life varies from 6 months to 2 years |
| Bluevua RO100ROPOT | Borosilicate glass carafe | 12-liter carafe | Filter monitor; stated 12–24 month life |
The Y9A keeps its refill tank attached to the unit. Bluevua instead supplies a separate glass carafe, which may suit a kitchen where you want to pour or serve from a glass container.

Which SimPure Y9A alternative suits your kitchen?
Choose AquaTru if named IAPMO certifications are your main deciding point and its 2.7-liter dispenser suits your routine. Its filter life varies from 6 months to 2 years, so check the filter schedule for each cartridge.
Choose Bluevua if a borosilicate glass carafe is more useful than an attached side tank. Its filter monitor tracks service life and water quality, and the stated filter life ranges from 12 to 24 months.
Choose the Y9A if its visible side refill tank, mineral stage and filter-change indicators match your priorities. The alternatives do not make the Y9A’s fit problem disappear: all three need a sensible place on the counter and power.
What mistakes should you avoid with the SimPure Y9A?
The most common buying mistake is measuring only the machine’s footprint. Check the full height, the 18 in clearance, the tank-removal path and the nearest outlet before ordering.
Don’t expect a zero TDS reading after remineralization. The ALK filter adds minerals after RO, so use the test documents for contaminant-specific questions instead of treating one TDS number as a full water-quality report.
Don’t stretch filter replacement intervals just because the water still tastes fine. Follow the indicator lights and SimPure’s recommended schedule, and use fresh feed water each day.
Don’t leave standing water in the system during a long absence. Follow the manual’s draining, drying and storage directions, especially for absences longer than a week or several months.
Should you buy the SimPure Y9A?
Buy the SimPure Y9A if you want countertop RO, can give it 18 in of vertical clearance, have room to remove its side tank and prefer remineralized water. Its daily refill and scheduled cartridge changes suit people comfortable with routine upkeep.
Skip it if you need a glass carafe, want near-zero TDS water, or cannot reach the tank from the side. Pick Bluevua when the carafe matters most, or AquaTru when its named certification standards matter more.
For a broader view of available layouts, compare countertop RO systems before choosing the setup that fits your counter and daily routine.
Frequently asked questions
Does the SimPure Y9A add minerals back to water?
