Pure water window cleaning only works while the water is actually pure. The IPC Eagle BD500409 filter set is the replacement pair for the HydroTube water-fed pole system: one carbon/sediment filter and one DI filter that together turn ordinary tap water into deionized water that dries spot-free, with no squeegee and no detailing.
Use Cases
Route window cleaners. Keeping a fresh set on the truck means a rising TDS reading in the middle of a route never turns into a callback for spotted glass.
Facility and campus crews. In-house teams cleaning storefronts, entryways, and low-rise glass from the ground keep their HydroTube producing pure water for pennies per gallon - IPC Eagle rates the system at under 3 cents per gallon with fresh filters.

Frequently Asked Questions
How often should HydroTube filters be replaced?
Replace the DI filter when your TDS meter starts reading above 0 to 10 ppm at the pole, because spotting begins as dissolved solids climb. The carbon/sediment filter is typically changed with the DI filter to protect the fresh resin.
What does each filter in the set do?
The carbon/sediment filter strips chlorine and particulate from tap water, protecting the DI stage. The DI filter then removes the remaining dissolved minerals, producing the pure water that dries spot-free on glass.
Does this set fit anything besides the HydroTube?
Yes. The BD500409 set is also used on the IPC Eagle Hydro Cart Compact pure water system.
Why do windows spot even though I am using pure water?
Spotting almost always means the DI resin is exhausted. Check the outlet TDS; if it reads more than about 10 ppm, install a fresh filter set before the next job.
