How do you ensure that your home has a steady supply of safe, filtered water without investing in a complex new plumbing system? Now there’s a simple, easy-to-install solution that filters your water right at the source: the Brio Premium Single Housing Filtration System.
This unit combines exceptional filtration with a compact, convenient style. It’s one of the only home filtration systems on the market that’s certified to NSF International’s Standard 53, protecting against lead, mercury, chlorine, and forever chemicals. And this sleek, under-sink unit connects directly to your cold water line with just a few twists of a wrench, making it easier than ever to trust your home’s water supply.
What is a Single Housing Filtration System?

Brio’s Premium Single Housing Filtration System is a high-quality, high-performing filtration system for your home that takes up much less space than most conventional under-sink units. Building on the popularity of our existing single housing filtration systems, this model offers NSF-certified performance with a premium aesthetic.
Crafted with a durable aluminum alloy housing that gives it an upscale build compared to a typical plastic model, this unit installs under your sink using basic tools, like a Phillips screwdriver and adjustable wrench—no complex plumbing required.
After installation, the cartridge becomes a low-maintenance addition to your household that requires only occasional filter changes. The cartridge lets you know when it’s time to replace these filters, which are available directly from Brio.
Once you’ve installed the cartridge, the system provides cleaner, safer water that meets NSF-certified standards—either directly from your existing faucet or through a dedicated secondary faucet.
This 2-stage filtration system is a major step up from basic filters, thanks to its combination of sediment filtration and enhanced carbon block capability. A reverse osmosis (RO) system is a more thorough way to filter water, but it can represent a significant additional cost.
What Problems Does a Single Housing Filtration System Address?
Consumers are becoming less trusting of municipal water quality. Brio’s Premium Single House Filtration helps restore that trust and provides safe, delicious water that encourages you to stay hydrated without relying on single-use plastic water bottles.
Unfiltered water may taste or smell unpleasant due to contaminants, such as disinfection byproducts and heavy metals like lead. Asbestos and Giardia cysts may also be present. These and other contaminants are associated with a range of health concerns, which may lead homeowners to avoid drinking tap water.
The Premium Single Housing Filtration System is engineered for your peace of mind. This unit features:
- Certification that meets international NSF/ANSI Standards 42 and 53, indicating a significant reduction in potential contaminants
- Certification to the NSF/ANSI Standard 372, a standard that shows lead-free compliance
- Certification that this filtration system reduces PFAS, also known as forever chemicals
It’s a simple way to make your tap water safer.
Who Benefits From This Type of System?

If you’ve been thinking about an easy upgrade to your existing home water filtration system, this unit is compact, stylish, and easy to install.
It’s also ideal for adding extra filtration in utility spaces or other small rooms that include a sink, where filtered water would be beneficial. RV users can take one on the road with them, never having to worry about hooking up to a poor-quality water source again.
The faucet-free option is particularly useful if you’re short on time or want a simpler installation experience. Simply connect the cartridge and its system to your cold water line and enjoy filtered water straight from your existing faucet.
When Should You Choose Single Housing Systems vs. Multi-Stage/RO?
Multi-stage filtration and RO systems are more complex and expensive than single housing options. They offer additional filtration, but they can be trickier to install and take up more space in your home. Brio offers a simpler solution that addresses the most pressing concerns about water safety and taste without complex installation requirements.
Opt for the Brio Premium Single Housing Filtration cartridge system if:
- You want a simple, single-cartridge undersink system
- You want to avoid complex plumbing or installation
- You want reliable, NSF-certified filtration without a full-house system
- You have particular concerns about lead or PFAS contamination
- You need to upgrade your older, plastic single housing system to a smarter, more durable aluminum option
You can even complement an existing multi-stage or RO filter with the Premium Single Housing Filtration System. Adding extra filtration at the cold water line reduces strain on existing systems and could increase their lifespan. That means fewer filter changes and the potential to save money over time.
