Frequently Asked Questions
How do I know which UV system is right for my home’s water usage?
The “GPM flow rate” indicates how much water the system can purify per minute. Check your household’s average water usage to choose a system with an adequate flow rate. Bigger homes usually need higher flow rates.
What does “multi-stage filtration” mean, and is it really necessary?
Multi-stage filtration removes sediment and other particles before UV disinfection. If you have well water or water with a lot of sediment, systems like the Bluonics will perform better. It helps the UV light work effectively by ensuring the water is clear.
How often do I need to replace the UV bulb, and how difficult is the replacement?
Most UV bulbs need replacing every 9,000 hours (about once a year). Some units include alarms to let you know when it’s time. Replacing the bulb is straightforward—like changing a lightbulb—but check guides to be sure.
I’m on a tight budget. Is the cheapest option safe, or should I spend more?
The HQUA offers a basic, safe option at a lower cost, plus it comes with an extra bulb. If your water is pretty clean to begin with, it’s worth considering. If your water is problematic, investing in multi-stage filtration provides better assurance.
I saw some comments about leaks during install. What can I do to avoid this?
Make sure to follow directions closely and to properly tighten all connections. Teflon tape is an easy way to get a better seal.
