Frequently Asked Questions
What does “GPM” mean, and how do I know what size system I need?
“GPM” stands for Gallons Per Minute. It measures the water flow rate that the UV system can handle. To choose the right size, think about how many faucets and appliances you might use at the same time. A smaller home can be fine with 11-12 GPM, while larger homes need 24 GPM or more.
Will these UV systems remove sediment or chemicals from my water?
Most UV systems primarily remove pathogens from your water. The Bluonics system also includes multi-stage filters that help with sediment and some chemicals. If sediment is a concern, additional pre-filters ahead of any other UV system is suggested. None of these systems reduce TDS.
How often do I need to replace the UV bulb, and how difficult is it?
Bulb replacement varies by models. The iSpring’s bulb last for 9,000- hours. Some include extra bulbs as well. Replacements for most systems is straightforward, and is similar to changing a lightbulb. Always disconnect power before beginning installation, or bulb replacement.
What does the “30 mJ/cm² UV dose” mean on the Solapur system, and why is it important?
The “30 mJ/cm² UV dose” refers to the amount of UV light that your water is exposed to. This dosage is important because it ensures very thorough disinfection for pathogens in your water. Check with local guidelines to find out what UV dose you may need.
Are these UV systems difficult to install? Do I need a plumber?
Many people can install the HQUA-OWS-121 or Geekpure UV models by themselves using the setup instructions. Other than that, professional installation may be needed. If you’re not comfortable working with plumbing, ask a license professional for help.
