# Piexo — Nanotechnology Air Freshener Dispensing System > Piezoelectric air freshener dispensing system by Draco Hygienic Products. No propellant, no VOCs, no metal cans. Commercial and residential air care. Made and filled in USA. Based in Montclair, California. ## What is Piexo? Piexo uses piezoelectric nanotechnology to atomize liquid fragrance into an ultra-fine 6-micron mist without aerosol propellant or heated gel. The droplets stay airborne for up to 2 hours. No metal cans to dispose of, no volatile organic compounds released. Greener, safer, more efficient than traditional aerosol air fresheners. The name "Piexo" is derived from "piezoelectric" — the technology discovered by Pierre Curie in the 18th century. A piezo disk generates voltage when deformed by force, which Piexo harnesses to atomize liquid fragrance. ## Two Formulations - **AIR FRESH**: 12 fragrance scents for restrooms, lobbies, HVAC systems, and scent marketing - **AIR CLEAN**: 2 odor-neutralizing formulations for hospitals, hotel guest rooms, and airports ## Dispensers | Model | Type | Refill | Coverage | Battery | Features | |-------|------|--------|----------|---------|----------| | SPXO 3-2 | Programmable | 120ml | 6,000 cu ft | 4×AA (up to 120 days) | LCD display, real-time clock, 5/7-day scheduling, 1-60 min intervals, spray counter | | SPXO 3-7 | Simple | 120ml | 6,000 cu ft | 4×AA | Set-and-forget 30 or 60-day setting | | HPXO 3-2 | HVAC Large | 330ml | 8,000 cu ft | 4×C-cell | Programmable, for large HVAC systems and multi-room coverage | ## Refill Fragrances ### 120ml Refills (for SPXO dispensers) — 14 scents Pure (PXO-000), Zero (PXO-001), Vanilla Mint (PXO-002), Rain (PXO-003), Raspberry Delight (PXO-004), Mango (PXO-005), Green Tea (PXO-006), Linen (PXO-007), Cucumber Melon (PXO-008), Grapefruit (PXO-009), Apple (PXO-010), Aqua (PXO-011), White Tea (PXO-012), Titan (PXO-013) ### 330ml HVAC Refills (for HPXO dispensers) — 3 scents White Tea (PXO-012H), Titan (PXO-013H), Gem (PXO-014H) ## Performance Stats - **6-micron droplets**: Ultra-fine mist stays airborne for up to 2 hours - **6,000 sprays** per 120ml refill (0.02ml per spray) - **Up to 24,000 cu ft** coverage with proper ventilation ## Key Differentiators vs Aerosol | Feature | Piexo | Traditional Aerosol | |---------|-------|-------------------| | Propellant | None — piezoelectric atomization | Compressed propellant gas | | VOCs | No added VOCs | Emits volatile organic compounds | | Container | Recyclable plastic refill | Metal aerosol can (landfill waste) | | Scheduling | LCD programmable (5/7 day, 1-60 min) | Fixed interval or manual | | Spray size | 6 microns (stays airborne 2 hrs) | Larger droplets, shorter airtime | | Made in | USA | Varies | ## Why Piexo Exists — 3 Reasons 1. **No Metal Cans**: Full plastic construction reduces landfill waste from conventional metal aerosol cans 2. **No Added VOCs**: Safer chemical formulations improve indoor air quality 3. **No Propellant Gas**: More product per refill, simpler manufacturing, lower energy use and cost ## Pages - [Home](https://piexo.com/): Brand overview and product introduction - [The System](https://piexo.com/#system): How piezoelectric atomization works - [Performance](https://piexo.com/#performance): 6-micron mist, 6,000 sprays, 24,000 cu ft coverage - [The Benefits](https://piexo.com/#benefits): No metal cans, no VOCs, no propellant - [Hardware & Refills](https://piexo.com/#hardware): SPXO and HPXO dispensers, 17 refill SKUs - [Fragrances](https://piexo.com/#fragrances): All 14 + 3 scent options - [Contact](https://piexo.com/#contact): Reach the Draco team ## Contact - Website: [piexo.com](https://piexo.com) - Email: [info@draco.com](mailto:info@draco.com) (US) / [ehsu@draco.com](mailto:ehsu@draco.com) (International) - Phone: 909.447.2300 - Fax: 909.447.2305 - Address: 4655 Brooks Street, Montclair, California 91763, USA - Parent company: Draco Hygienic Products Inc. — OEM manufacturer since 1995
