Not every site needs a programmable dispenser, and complexity is how units end up set wrong or switched off. The Bioion RX900 LED is the deliberately simple option: three simple setting steps and three spray time intervals, and that is the entire interface. Any staff member can set one correctly on the first try, which is what makes it the practical choice when you are rolling out dozens of units across floors, branches or franchise sites. It is battery-operated on AA alkaline cells, so it mounts anywhere without wiring — living halls, bedrooms, offices, lobbies, pantries and washrooms. Pair it with Bioion Air Purifier aerosol for Ambience in any of up to nine fragrances. For scheduling control by minute, hour and day, choose the RX900 LCD instead. Corporate and bulk supply available from the official Philippine distributor of Bioion®.
