Questions before you choose?
See all questionsDoes HALO 5 need salt or replacement cartridges?
HALO 5 uses salt-free scale conditioning and a backwashing media tank. There are no disposable cartridges to change. The control valve needs power and the backwash needs a drain. Confirm the service plan for your water and model with the installer.
Can I use a HALO system on well water?
Start with a current laboratory report. HALO asks to review that report before recommending a system and conditions applicable warranty coverage on that review. Confirm the exact model and its written terms before installation.
Should I add reverse osmosis at my kitchen sink?
A whole-home system treats the water at the main line. An under-sink RO unit targets specific drinking-water concerns at one outlet. Look at your water report and the model’s performance data to decide whether you need both.
What affects the price of a system?
A quote depends on the equipment, water test results, pipe size, household flow and installation conditions. Check the space near the main line and tell the installer whether it has power and an accessible drain.
