Looking to upgrade your home or business's water filtration system? The Delta Clarifi™ and Brizo Pristine™ tankless under-sink reverse osmosis (RO) systems are two of the most advanced options available. These compact systems provide freshly filtered water on demand while saving space and optimizing efficiency. They’re packed with features designed to eliminate common contaminants, simplify maintenance, and elevate the quality of your drinking water.
To help you choose the right option, we’ve revised and clarified important details on their performance, certifications, and noise factors, ensuring you have the clearest, most accurate information to make the best decision for your needs.
Why Tankless Reverse Osmosis Is a Game-Changer
Traditional RO systems often rely on bulky storage tanks that take up significant under-sink space and operate with lower efficiency, wasting large amounts of water. Tankless systems, like the Delta Clarifi™ and Brizo Pristine™, solve these problems. They remove contaminants through multi-stage filtration and offer impressive filtered-to-waste water efficiency ratios, all within a sleek, compact design.
With these systems, you’re not just conserving space - you’re also improving sustainability and gaining access to smarter features like filter-life tracking and optional remineralization for enhanced taste and pH balance.
Reverse Osmosis in a Nutshell
Reverse osmosis purifies water by pushing it through a semi-permeable membrane under high pressure. This process is highly effective at removing impurities, including lead, arsenic, PFAS, microplastics, nitrates, and many other harmful substances. Both the Delta Clarifi™ and Brizo Pristine™ utilize this method, but their differences lie in the details of their performance.
Delta Clarifi™ Tankless RO System Features
The Delta Clarifi™ is designed with convenience and versatility in mind. Here’s what sets it apart:
Advanced Filtration
The Delta Clarifi™ is certified to reduce over 90 contaminants, including chlorine, chloramine, microplastics, PFAS, lead, arsenic, heavy metals, and pharmaceuticals. However, the system does not reduce iron, and there are conflicting reports about its ability to remove bacteria and microorganisms. Some sources suggest 0% bacteria reduction, while others claim some level of efficacy. For this reason, we recommend contacting the manufacturer directly to confirm the system's microbial reduction capabilities.
Impressive Water Efficiency
This system achieves a 78% efficiency rating with a 2:1 filtered-to-waste water ratio, making it up to 87.5% more efficient than traditional systems with a 1:4 ratio. This improves sustainability while reducing water bills over time.
Space-Saving Design
With a tank-free setup about the size of a desktop computer tower, the Delta Clarifi™ saves over 60% of under-sink space compared to bulky tank systems, giving you more storage and flexibility.
Smart Maintenance and Hard Water Tolerance
The system alerts you when filters need replacing, thanks to indicator lights and audible notifications. The carbon and RO filters last for 2 years or 1,320 gallons, while the pre-filter lasts 6 years or 3,960 gallons. Its certification to handle hard water conditions without reducing efficiency is another standout feature, particularly for areas with challenging water profiles.
Optional Remineralization
An optional remineralizer cartridge can be added to reintroduce essential minerals like calcium and magnesium, improving water taste and pH balance for a healthier and more enjoyable experience.
Noise Levels
One user reported a "jarring humming noise and vibrations" during operation and cycling. While this has not been widely confirmed, it could be a consideration for noise-sensitive households.
Brizo Pristine™ Tankless RO System Features
The Brizo Pristine™ takes performance and convenience to another level with its focus on filtration strength and smart features.
Superior Filtration
The Brizo Pristine™ is certified for over 90 contaminants and shines in its ability to reduce more than 99% of bacteria, viruses, and cysts, as well as total PFAS, lead, and heavy metals. This makes it a top choice for households prioritizing maximum microbial protection.
Water Efficiency and Space Optimization
With a 74% efficiency rating and a 2.5:1 filtered-to-waste water ratio, the Brizo Pristine™ offers slightly better sustainability compared to the Delta Clarifi™. The system also features a compact tankless design, saving 60% of under-sink space.
Intelligent Maintenance Features
Filter-life tracking is streamlined with integrated indicator lights (blue for normal, purple for nearing expiration, and red for expired) and audible alerts. The synchronized lifespans for the RO and carbon filters are 2 years or 1,320 gallons, and its pre-filter lasts 6 years or 3,960 gallons, making replacements straightforward and manageable.
Optional Remineralization
Like the Delta system, the Brizo Pristine™ supports an optional remineralizer cartridge for taste and pH enhancement, giving you fresher, better-balanced water.
Noise Levels
The Brizo Pristine™ system has not been associated with notable noise complaints based on available data, making it a potentially quieter option for sensitive environments.
Internal Leak Detection
A built-in leak detection system adds peace of mind, further enhancing its smart, user-friendly design.

Maintenance Made Simple
Both systems benefit from straightforward maintenance schedules. Regularly replacing filters ensures optimal performance and water quality. Replacement is quick and easy—cartridges can be swapped out in less than a minute. For either system, here’s what to keep in mind:
- Pre-Filter – Replace every 6 years or 3,960 gallons.
- RO and Carbon Filters – Replace every 2 years or 1,320 gallons.
- Optional Remineralizer – Replace based on usage.
Considering these schedules not only simplifies upkeep but secures long-term system efficiency, especially important in areas with high total dissolved solids.
