Bluevua RO100ROPOT-UV Countertop Reverse Osmosis System Review 2026
The Bluevua RO100ROPOT-UV is the best countertop RO system for health-conscious users who want hospital-grade purification without any installation. The UV stage and glass carafe justify the premium over the Lite model.
Overview
The Bluevua RO100ROPOT-UV is designed for people who want the purest possible drinking water without touching their plumbing. This countertop reverse osmosis system combines a 6-stage filtration process with UV-C sterilization and mineral remineralization, delivering hospital-grade purification directly on your kitchen counter. At $317, it sits at the premium end of countertop filters, but the combination of RO, UV, and a glass carafe sets it apart from everything else in this category.
What makes this unit particularly compelling is the glass carafe. Most countertop RO systems store purified water in plastic tanks, which can leach BPA or other chemicals back into the water you just spent time purifying. The RO100ROPOT-UV eliminates that concern entirely. The UV sterilization stage adds another layer of protection, killing 99.99% of bacteria and viruses that might survive the RO membrane — a genuine safety advantage for households with immunocompromised members or those on well water.
The trade-off is speed and space. This unit produces about 0.75 gallons per cycle and takes up a meaningful chunk of counter real estate. If you need instant filtered water for cooking large meals, you will find the batch process limiting. But for daily drinking water, the quality is genuinely outstanding.

The 6-stage process runs water through PP cotton pre-filtration, a carbon block, the RO membrane (0.0001 microns), post-carbon polishing, UV-C sterilization, and finally an alkaline remineralization stage that adds calcium and magnesium back for improved taste and health benefits. The 2:1 pure-to-drain ratio means for every 2 gallons of purified water, only 1 gallon goes to drain — significantly better than the 1:3 ratio common in under-sink RO systems.
Pros & Cons

Performance & Real-World Testing
In testing with municipal tap water averaging 280 TDS, the RO100ROPOT-UV consistently produced water in the 10-20 TDS range — a 93-96% reduction. The UV stage provides an additional safety net, particularly valuable for anyone filtering well water or water from questionable sources. Taste improvement is immediately noticeable: the flat, chemical tang of chlorinated tap water is completely eliminated, replaced by clean, slightly mineralized water from the remineralization stage.
A full cycle takes approximately 15-20 minutes for 0.75 gallons, which means you need to plan ahead rather than expecting on-demand filtered water. The unit operates quietly enough to run in the background during normal kitchen activities — noticeably quieter than a dishwasher. The glass carafe keeps water fresh without any plastic aftertaste, even after sitting for several hours.
Long-term reliability has been solid based on user reports across nearly 2,800 Amazon reviews. The most common complaint involves the drain hose: it needs to be properly positioned in the sink during operation, which can be mildly inconvenient. Some users solve this with a small clip or holder near the faucet.
Value Analysis
At $317, the RO100ROPOT-UV is a significant investment for a countertop filter. However, compared to under-sink RO systems that cost $200-500 plus installation, it offers comparable purification with zero installation expense. Annual filter costs run approximately $60-80, bringing the first-year total cost of ownership to around $380-400. Over three years, the per-gallon cost works out to roughly $0.08-0.10 — far cheaper than bottled water and competitive with under-sink RO on a per-gallon basis.
The UV sterilization and glass carafe are the two features that justify the premium over the Lite UV model at $219. If you are on well water or have specific concerns about bacteria and viruses, the UV stage alone may be worth the $98 difference. If your water source is already chlorinated municipal water, the Lite UV delivers 90% of the performance at 70% of the price.
