HaB

What HaB does

HaB, trading as Lungentrainer and operating lungentrainer.de, is a German online specialty retailer of respiratory training and respiratory therapy devices headquartered in Winsen (Luhe). The company distributes a broad catalog covering inspiratory muscle training (IMT), expiratory muscle training (EMT), positive expiratory pressure (PEP) therapy, sustained maximal inspiration (SMI) devices and electronic biofeedback systems, spanning entry-level accessories (€5.99 Flow-Ball ULTRA), mid-range mechanical IMTs (POWERbreathe Plus/Classic at €50–€77), professional electronic trainers (POWERbreathe K1/K3/K4/K5 from €565–€829) and a medical-grade device (POWERbreathe KH2 at €2,139) bundled with Breathe-Link Medic Live Feedback software. The technical layer rests on third-party IP — most notably POWERbreathe's patented self-optimizing conical flow resistance and intelligent tapering system — plus Bluetooth integration with the ActiBreathe app and PC-based Breathe-Link analysis software.

The customer base spans individual consumers, athletes, musicians (particularly wind/brass players and singers), families, and B2B professional buyers including speech therapists, physiotherapists, pharmacies, sports clubs and music schools. Several SKUs are registered as medical devices and some carry Hilfsmittelnummer designations enabling partial reimbursement by German statutory health insurers. Distribution is primarily direct via the lungentrainer.de e-commerce storefront with phone, email and WhatsApp consultation; Switzerland is served indirectly through a distribution partner, healthmg GmbH. HaB is ISO 9001 certified (most recent certificate dated 2025-04-07), privately held, with 1–10 employees and no publicly disclosed revenue or external funding.

Broad incumbents

• ResMed: Global respiratory and sleep therapy leader producing ventilation, airway clearance, and diagnostic devices. Comparable to HaB because both serve chronic respiratory patients (COPD, asthma, cystic fibrosis) with DME-grade devices, though ResMed operates at global scale across sleep-disordered breathing as well.
• Vitality Medical: Large US online retailer of DME, respiratory therapy, and diagnostics products. Comparable in business model (online DME retailer with B2B/wholesale motion) even though geographic and reimbursement systems differ from HaB's German market.
• Beurer: German health-and-wellness device manufacturer whose nebulizer (e.g., Beurer IH 47) is retailed by HaB. Beurer also sells direct to consumers and through pharmacies, making it both a supplier and a competing channel for overlapping respiratory therapy SKUs.
• Philips Respironics: Respiratory therapy division of Philips selling PEP/oscillatory PEP devices, incentive spirometers, and nebulizers that overlap with HaB's mucus-clearance and inhalation portfolio. Operates broadly across hospital, clinical, and consumer channels — a large incumbent that defines the standard of care HaB's IMT/PEP products compete against.
• CareFusion (BD): BD-owned respiratory portfolio (formerly Vyaire/CareFusion) producing incentive spirometers and PEP devices that compete with HaB's TRI-BALL, COACH 2 plus and Triflo II products. Hospital-channel incumbent that defines clinical procurement HaB's B2B therapists must navigate.

Emerging players

• Airofit: Denmark-based smart respiratory muscle trainer with Bluetooth/app biofeedback — directly comparable to POWERbreathe K-Series products HaB sells, including the same Smart Adapter + app pairing model. Targets athletes and COPD patients via subscription/online channels.
• AirPhysio: Australian D2C brand selling OPEP / lung-expansion devices direct-to-consumer globally, directly competing for the same IMT/PEP customer as HaB. Less catalog depth but similar GTM: education-led content, sports/medical dual-segment marketing, online-first sales.

Direct peers

• POWERbreathe International: UK-based inventor and primary manufacturer of the POWERbreathe IMT/EMT/K-Series product line that HaB retails. HaB is effectively a key German reseller for the same SKUs customers can buy directly from POWERbreathe — making them the most direct comparable for product, brand, and customer overlap.
• RC-Medical (RC-Cornet): German manufacturer of the RC-Cornet and RC-Cornet PLUS NASAL oscillating PEP devices HaB retails. Comparable because it is a focused German respiratory-DME specialist selling similar mucus-clearance devices through prescriptions and online channels.

Others

• Healthmg GmbH: Swiss distribution partner HaB explicitly uses to serve customers it cannot ship to directly. An ecosystem participant rather than direct competitor, but relevant because it is the precedent HaB would extend to expand DACH coverage.
