Cons
Initial Installation May Be Challenging for Non-DIY Users
While many users successfully install the system on their own, those without prior DIY or basic plumbing experience may find the initial setup slightly challenging. Tasks such as drilling through granite or stone countertops can be intimidating without the right tools or experience. In these cases, professional installation may be preferred, which could add to the initial cost. However, once installed, ongoing maintenance is generally straightforward.
Replacement Filter Costs Can Add Up Over Time
Although the filters are designed to last up to 12 months, some users consider the cost of replacement filters relatively high compared to basic pitcher-style filters. For households with high water usage, annual replacement costs should be factored into the overall ownership expense. That said, the longer filter lifespan and improved water quality often offset the higher upfront replacement cost for many users.
Faucet Installation Can Be Tight in Confined Spaces
Installing the faucet can be somewhat tricky due to limited space beneath the sink. Tightening the faucet nut often requires working in a confined area, and some users report that having an extra pair of hands makes the process easier. While this is a one-time inconvenience, it may be frustrating for those installing the system alone.
Water Flow Rate Depends on Filter Condition
The system provides an adequate flow rate for everyday use, but users may notice a gradual reduction in water flow as the filter approaches the end of its service life. This is a common characteristic of multi-stage filtration systems and serves as a practical indicator that a filter change is needed. Timely replacement helps maintain optimal flow and filtration performance.
Not Designed for Ultra-Low TDS Filtration
For users seeking extremely low Total Dissolved Solids (TDS) levels, this system may not fully meet expectations. Unlike reverse osmosis systems, it is designed to retain beneficial minerals while removing contaminants. As a result, TDS levels remain higher than RO-filtered water, which may not appeal to users who prioritize ultra-purified water over mineral retention.
Faucet Size May Feel Smaller Than Expected
Some users note that the included faucet appears smaller than anticipated. While this can be a drawback for those expecting a more prominent fixture, others appreciate the compact size for its clean, unobtrusive appearance. Ultimately, this point is more subjective and related to personal aesthetic preference rather than functional performance.
Occasional Delays in Replacement Filter Availability
There have been occasional reports of short delays in the availability of replacement filters. While this is not a frequent issue, it may be inconvenient for users who postpone ordering replacements until the last minute. Planning ahead and purchasing filters in advance can help avoid interruptions in filtration performance.
