Frequently Asked Questions
How do I know which GPM (gallons per minute) flow rate is right for my home?
Think about how many water-using appliances you might use at the same time. A higher GPM means it can handle more simultaneous use without losing pressure. For a small home with one or two people, an 11 GPM system like the Solapur might be enough. Larger households might need 24 GPM like the Bluonics.
What’s the deal with the different stages of filtration, like in the Bluonics system?
More stages mean finer filtration. The Bluonics uses a four-stage process to remove sediment, chemicals, and other impurities before the UV light disinfects. This helps the UV light work better and extends the life of the system.
How hard is it to maintain these systems, especially changing the UV bulb?
Most systems require annual bulb replacement. Some, like the iSpring, have a lamp that lasts around 9,000 hours. The Geekpure is designed to be easy to maintain. The HQUA-OWS-121 includes a spare! Check the product descriptions for how-to videos and guides.
Do these systems change the taste or odor of my water?
UV systems are great because they don’t add anything to your water. They use UV light to disinfect, so you shouldn’t notice a change in taste or odor. Systems that have a multi-stage filter might even improve taste and reduce odors.
The Solapur system says it targets specific pathogens. What does that mean?
The Solapur system uses a specific wavelength of UV light that the manufacture has proven to kill a range of pathogens, including certain viruses and bacteria. The system alarms let you know everything is working correctly.
