Bluevua RO100ROPOT Review: Lab Analysis & Hands-On Testing

Full Analysis of the Bluevua RO100ROPOT

Filtration: 4.50/5.00

The Bluevua ROPOT scored 4.50/5.00 for filtration. How? Most importantly, it achieved excellent results in our 2024 and 2025 lab testing and the filtered water had a clean taste (pleasant mineral taste when using the optional mineral cartridge) and no odor. While this system has extensive 3rd party testing for contaminant removal, at least some was not performed over the full filter life, and it only has 2 pending NSF/ANSI certifications for contaminant reduction.

1. Lab Results: 5.00/5.00 (2025) & 5.00/5.00 (2024)

In our 2024 and 2025 lab tests comparing an unfiltered and a filtered tap water sample, the Bluevua ROPOT could remove 13 undesirable impurities and contaminants to below the minimum detection level (so essentially to 100%): chlorine, bromodichloromethane, bromoform, dibromochloromethane, chloroform, copper, barium, lithium, iron, aluminum, manganese, zinc, and nitrate.

The following substances remained in our water:

• Boron was reduced by a high 90% in 2024 and was completely removed in 2025.
• Strontium was reduced by a very high 98% in 2024 and was completely removed in 2025.
• Fluoride was reduced by a minimum of 76% (solid) and up to 99% (very high) in 2024. This range indicates some fluoride remained in the water but it was so little that the lab couldn’t quantify precisely how much was left. In our 2025 lab test, we used a different and more precise fluoride detection method and fluoride was completely eliminated. This aligns with Bluevua’s own published performance data of 98.57% to >99.38% fluoride reduction. Based on this, we believe the true reduction in 2024 was likely in the high-90% range as well.

Finally, TDS decreased by 91% in 2024 and by 86% in 2025. While TDS should not be interpreted independently, as it does not override inadequate removal of individual contaminants, ≥90% TDS reduction is high and shows that the RO membrane works as intended. ≥85% is still good but not as high as the more effective RO systems. That said, we utilized the optional remineralization cartridge in our 2025 test, which adds beneficial minerals back into the water and increases its TDS. Consequently, the slightly lower amount of TDS removal in 2025 is expected.

Remineralization Results

Using the optional remineralization cartridge in our 2025 lab testing, we measured 4.5 ppm magnesium and 0.404 ppm calcium post-filtration, neither of which were within their respective WHO health guidelines (minimum 10 ppm, optimal 20-30 ppm for magnesium and minimum 20 ppm, optimal ~50 ppm for calcium). While these levels were higher than those observed in the non-remineralized RO systems we tested (average of 0.11123 ppm magnesium and 0.47253 ppm calcium), they still reflect limited mineral restoration.

Post-remineralization pH increased to 9.8 (compared to an average of 6.72 without remineralization), and alkalinity rose to 30 ppm – within the recommended range of 30–400 ppm and substantially higher than the 2.2 ppm average of non-remineralized systems. However, elevated pH in particular should not be interpreted as indicators of adequate mineral content, as direct mineral concentrations remained low.

Overall, the mineral cartridge improved buffering capacity and taste-related parameters but did not meaningfully restore essential minerals to health-recommended levels.

That said, our remineralization lab results represent a standardized, worst-case scenario designed to reflect the shortest possible contact time between purified RO water and remineralization media, ensuring consistency across all tested systems. Additional testing using TDS meters and extended contact times showed considerably higher TDS levels, suggesting increased mineral dissolution under those conditions.

This minimal-contact approach may therefore underrepresent real-world remineralization performance, especially for systems like the Bluevua ROPOT, where the mineral cartridge is positioned in the carafe lid. In this design, water contacts the remineralization media during dispensing and remains in prolonged contact when the carafe is filled, as the cartridge becomes partially submerged. As a result, mineral release during everyday use is likely higher than reflected in our lab measurements, though actual performance can still vary based on contact time, water chemistry, fill level, and usage patterns.

2. NSF/ANSI Certifications and Other Test Data

The Bluevua ROPOT only has 2 pending NSF/ANSI certifications for contaminant reduction (for TDS and chromium 3) against NSF/ANSI standard 58. However, these certifications have been pending since 2024, and as of February 2026, they are still not listed in the WQA database.

This system does have 3rd party testing for ~90 contaminants but it doesn’t reference NSF/ANSI standards for most; plus, some of this testing appears to have been performed at the start of the filter life rather than throughout the entire filter life.

Reported reduction rates include:

• Several organics, including VOCs, pesticides, and herbicides (90.00-99.99%+)
• TDS (91.24%)
• Chromium 3 (99.30%)
• Chromium 6 (>96.04%)
• PFOA (>97.36%)
• PFOS (>99.25%)
• coli (>99.99%)
• Total coliforms (>99.99%)
• Barium (>99.79%)
• Beryllium (>99.96%)
• Fluoride (>99.38%)
• Aluminum (>95.93%)
• Arsenic (>99.69%)
• Iron (>99.02%)
• Lead (>99.99%)
• Manganese (>99.89%)
• Mercury (>98.04%)
• Thallium (>99.88%)
• Cyanide (>97.96%)
• Nitrate (>91.28%)
• Free chlorine residual (>98.97%)

Reduction rates are per Bluevua’s third-party test reports.

3. Filtration Process

We have 4 filter cartridges which comprise 4 filtration stages, plus an optional fifth remineralization cartridge.

• Stage 1 is performed by a 5-micron PP sediment pre-filter. The polypropylene sediment filter is mechanical filtration – it acts like a sieve to remove solid, undissolved particulates such as dirt or rust.
• Stage 2 is a 0.5-micron coconut-shell carbon block pre-filter. Activated carbon removes things like bad tastes and odors, chlorine/chloramine, disinfection byproducts and other organics, as well as certain metals. By removing chlorine and other contaminants, this pre-filter protects the RO membrane from damage. In addition, the block structure provides fine mechanical filtration due to its smaller pore size compared to granular carbon.
• Stage 3 is performed by the RO membrane, which uses reverse osmosis to effectively remove the vast majority of contaminants and minerals.
• Stage 4 is a 0.1-micron coconut-shell carbon block post-filter, which acts as a “polishing” filter to remove lingering bad tastes/odors, VOCs, and fine particulate matter.
• Optional: the remineralization post-filter restores minerals like calcium, sodium, magnesium, potassium, and zinc, raises the pH to prevent acidity and boosts the water’s flavor.

4. Taste and Odor Tests

In our 2024 and 2025 tests, the filtered water was odorless and had a perfectly clean taste. The optional remineralization filter (2025) adds a nice, light mineral taste.

Usability: 4.61/5.00

The Bluevua ROPOT achieved a usability score of 4.61/5.00, based on its performance in the following categories:

1. Initial system assembly including filter priming (0.80/0.80)
2. Everyday use (3.31/3.70)
3. Filter replacements (0.50/0.50)

1. Initial Setup: 0.80/0.80

Assembling the Bluevua ROPOT is easy. In addition to clear, illustrated directions in the user manual, there is a tutorial video on YouTube.

Here’s a quick breakdown of the setup procedure:

1. Wash the feed tank and carafe with soap and rinse.
2. Plug the power adapter into the power outlet and into the port on the back of the machine, then turn the power switch to “on.”
3. Fill the feed tank with tap water up to the MAX fill line. Install feed tank and carafe into the unit.
4. Press the water volume button to choose preferred volume (~0.13, ~0.26, or ~0.45 gal); the carafe icons on the display panel flash to indicate the selected volume.
5. Press the water-making button to begin filtering. When filtering is complete, discard the wastewater remaining in the feed tank and the water in the carafe.
6. Repeat steps 3 through 5 five times to flush out the protective liquid in the filters before drinking. The water is NOT drinkable during the flushing process.
7. During the first 1-2 filtration cycles, the water in the feed tank will automatically fill the filters, and there may be no clean water produced. For cycles 3-5, it is normal for the filtered water to appear black or grey due to the activated carbon particles released by flushing the filters.
8. Now your Bluevua ROPOT is ready to use.

2. Day-to-Day Use: 3.31/3.70

2.1 Speed & Water Capacity: 1.01/1.40

The Bluevua ROPOT is well-suited for daily use. Firstly, its good-sized carafe stores plenty of water for later – up to ~8 cups (~0.5 gal) after filtering a full feed tank (0.95 gal). Consequently, you can fill a 40-oz bottle on a single refill all in one pour – no need to perform multiple feed tank refills or wait for additional cycles of water processing.

More specifically and based on a single feed tank, in our test the system could dispense 63 oz (one full carafe) of ambient water in one continuous pour. This is slightly more than the estimated ~60 oz (7.2 cup) maximum volume advertised by the manufacturer. Rounding up, we estimate 4 or 5 daily refills for the average US and US-family households, respectively – more than the average countertop RO.

In addition, the Bluevua filters fast enough to meet the daily water needs of the average-sized US households, and it can handle thirst bursts. In our ambient water speed tests, it could dispense 1 or 4 cups instantly when the water was pre-processed, meaning the feed tank was filled and allowed to fully filter all its water first. This is because we are pouring directly from a full carafe – no wait time for water processing needed. Upon refilling, it took 3:28 min to dispense 4 cups of water.

2.2 Dispensing: 1.00/1.00

Dispensing water is easy using the front panel’s two buttons: the first for selecting water volume – ~0.13, ~0.26, or ~0.45 gal – and the other to start filtration.

The carafe has a comfortable handle, slides in and out of the base easily, and provides a smooth stream without splashing, even when pouring fast.

If you use the optional mineral cartridge, it is placed inside the carafe lid. Filtered water passes through the cartridge as it is dispensed into the carafe. After dispensing, the water remains in contact with the minerals as long as the carafe is full and the cartridge stays submerged. The result: water from a full carafe that sits for longer periods before pouring can have a higher mineral content.

2.3 Refilling & Size: 0.70/0.70

Refilling the Bluevua ROPOT is straightforward. The very accessible feed water tank sits on the back corner of the unit, rather than completely behind it, making it easy to remove, refill, and place back on its base.

We also appreciate the simplicity of refilling: one full feed tank produces one carafe of water in about 10-15 minutes. You simply discard the feed tank’s wastewater and refill after each full cycle. However, if there is still some water left in the carafe when you initiate a new filtration cycle, it might fill up before the entire feed tank has processed.

The Bluevua ROPOT does not have a standard water shortage/change indicator light on its LED display for instances like these. However, once the feed water goes below a threshold level, specifically below the white cylinder inside the tank, the machine will emit a beeping sound and the filtering process will stop to control the concentration of the RO wastewater. In addition, the system enters a lock mode if it detects that the feed tank has not been removed for emptying wastewater after filtration.

Measuring 10.9″x15.4″x14.3″ (WxHxD), the Bluevua fits under standard height (18”) kitchen cabinets, and at 22 lb, it’s heavier than the average countertop RO systems we tested. It has a larger-than-average footprint compared to the other tested systems as well, occupying 155.87 in² (~1.08 ft²), and at almost 11” wide it is not streamlined enough to fit in narrow spaces.

2.3 Other: 0.60/0.60

The carafe fits in the fridge for chilling and has markers to help you meet your hydration goals.

This system also offers automatic TDS monitoring of both the feed and filtered water, which provides insight into the current state of your RO membrane and can be used along with the filter replacement indicators to determine the ideal time to change your filters. In our testing, we found the measurements to be consistently within 15-20 ppb using a separate meter so reasonably accurate.

3. Filter Replacements: 0.50/0.50

Filter replacements are easy as the filters are easily accessible through the side panel and quickly twist in/out.

The filter change indicator lights on the control panel alert you when it is time to change each filter. Rated filter life for the PP sediment pre-filter, carbon block pre-filter, and carbon block post-filter is 538 gal or 12 months; the RO membrane is 1,076 gal or 1-2 years. (The optional remineralization post-filter lasts 260 gal or 6 months.)

Assuming 500 gallons of yearly water consumption for the average household, we predict the frequency of your filter changes will be dictated by filter age rather than water consumption. Therefore, expect to replace the various components every 12-24 months as indicated (every 6 months for the mineral cartridge).

Costs: 4.24/5.00

Based on value for money, the Bluevua RO100ROPOT achieved a cost score of 4.24 out of 5.00, indicating it is relatively inexpensive for what it offers compared to competing systems (a score of 4.00 represents average value). Notably, while its upfront price is slightly above average, its annual filter replacement cost is slightly below average among the countertop RO systems we tested.

1. Upfront Price

As of November 4, 2025, the Bluevua is priced at $389. This is slightly above the $321.89 average across all the countertop RO systems we tested.

2. Long-Term Expenses for Filter Replacements

Based on 500 gallons consumption and a 538-gal or 12-month filter life (PP sediment pre-filter, carbon block pre-filter, and carbon block post-filter) and 1,076-gal or 1 to 2-year RO membrane life we estimate $120 (possibly up to $150) in annual filter replacement costs for the Bluevua ROPOT, which is slightly below the $149.47 average across all the countertop ROs we tested.

Using the optional remineralization post-filter rated at 260 gallons or 6 months adds another $34 yearly.

3. Product Warranty

The system is covered by a 1-year warranty.

4. Other Cost Factors

• The carafe is made from borosilicate glass.
• Built-in TDS meter provides measurements of both the feed and filtered water.

Additional

1. Pure-to-Drain Ratio Tests

We measured a pure-to-drain ratio of ~1:1.03 (2024) and ~1:1.16 (2025), which is high wastewater for a countertop RO system and worse than the average ~1:0.61 ratio across the countertop ROs we tested.

2. Construction

This system feels sturdy and well built, including the glass carafe.

3. Design

The Bluevua ROPOT has a modern yet classic appearance.

4. Simple Maintenance

This system performs automatic flushing for 18 seconds each time it is powered on, before each filtration cycle, and after a power outage, countering TDS creep and extending RO membrane life. In addition, you can manually backflush for 1 minute by pressing the water volume button and water-making button simultaneously, which removes contaminants and dirt deposited on the filters. This is helpful if you want to completely empty the internal clean water tank, or if you want to flush the system after not having used it for a while. However, flushing produces wastewater.

5. Frequent Customer Complaints

We read about issues with leaking from the base, tank seams, and connections. Other customers complained of extremely slow filtration, sometimes stopping mid-cycle.

We did not experience these issues firsthand.

Bottom Line: Runner-Up Countertop RO System If You Want a Glass Carafe (4.47/5.00)

Filtration weighted at 60%, and usability and cost at 20% each, the Bluevua ROPOT scored a final rating of 4.47 out of 5.00.

If you seek a countertop RO system with a glass carafe, the Bluevua ROPOT is among our top picks. It balances highly effective filtration with reasonable costs and user-friendly features.

Importantly, the system achieved a commendable 4.50/5.00 in our filtration analysis. It produced odorless, clean-tasting water and completely removed all contaminants in our 2025 lab tests (nearly all in 2024). However, it only has 2 pending NSF/ANSI certifications for contaminant reduction, and while it has extensive 3^rd party testing for contaminant removal, it may not have been to NSF/ANSI standards and at least some was not done to the full filter life.

The Bluevua ROPOT is also very easy to setup, use, and maintain. With a slightly above-average upfront price but below-average ongoing costs, this system is a great option for effective filtration with the added appeal of a sturdy glass carafe.
