Direct peers

• Zehnder Group: Swiss-listed manufacturer of indoor climate systems including decentralized and centralized ventilation with heat recovery. Closest direct peer given overlapping product categories (residential HRV/ERV), target customers (architects, installers, homeowners), and European premium positioning.
• Helios Ventilatoren: German manufacturer of fans, ventilation systems, and air-handling units for residential and commercial applications. Direct competitor in decentralized and small-room ventilation, sharing the same Made-in-Germany positioning and German installer/architect channel.
• Blauberg Ventilatoren: German/European manufacturer of fans, air handling units, and heat recovery ventilation systems for residential and commercial buildings. Competes head-to-head with LUNOS in single-room HRV/ERV and exhaust fan segments across European distribution.
• Maico Ventilatoren: German specialist in ventilation fans and air-handling technology with strong presence in bathroom, kitchen, and decentralized residential ventilation. Direct peer with comparable Made-in-Germany positioning and installer-channel go-to-market.
• Vents (Vents Group): European manufacturer of ventilation equipment (fans, air handling units, heat recovery ventilators) serving residential and light-commercial markets. Overlaps with LUNOS on small-room exhaust and heat-recovery product lines across European channels.
• Aldes: French group manufacturing ventilation, air-to-air heat recovery, and indoor air quality solutions for residential and commercial buildings. Comparable product portfolio (single-room HRV/ERV, exhaust fans, IAQ controls) and similar European distribution model.
• Siegenia-Aubi: German manufacturer of building elements including ventilation systems, smart-home aerators, and window-integrated ventilation units. Overlaps with LUNOS in decentralized residential ventilation and shares German premium positioning and installer/architect channels.

Emerging players

• Duco Ventilation & Sun Control: Belgian manufacturer of demand-controlled mechanical ventilation (MVHR/DMV) for residential applications, with strong presence in low-energy and renovation projects. Comparable decentralized/zone-based residential ventilation proposition, though typically ducted rather than fully room-by-room.

Broad incumbents

• Systemair: Swedish-listed broad HVAC and ventilation manufacturer with extensive residential and commercial product lines including heat recovery units. Larger and broader portfolio than LUNOS, but directly competitive in residential HRV where portfolios overlap.
• Broan-NuTone: North American leader in residential ventilation (bath/kitchen fans, range hoods, ERV/HRV) under multiple brands. Broader incumbent portfolio with overlapping product categories (exhaust fans, residential heat recovery) though different geographic focus.
