Wanted a thinner, flatter profile air hose for your BedJet setup? Or having trouble with an unusual bed frame where your existing round hose doesn’t bend tightly enough? This optional upgrade item replaces the round air hose that comes standard in the BedJet box. The flat air hose has a special, thinner rectangular shape that is lower profile against your bed and bends much more tightly than the factory standard round hose included with every BedJet. Simply unplug the standard round air hose (3.5" diameter) that came with your BedJet, and click-snap the flat hose (2.5" wide) onto your existing BedJet instead, so you can route airflow to your desired location more easily and discreetly. Works with all BedJet models including V1, V2 and BedJet 3 and existing air hose extensions. NOT COMPATIBLE WITH BEDJET AROMATHERAPY ACCESSORY. Verified Reviews from Real BedJetters
