Air. We breathe it without thinking. Keeping it that way in the modern, airtight home calls for class-leading ventilation performance – which you’ll find in every product in the Itho range. Whether you need continuous mechanical extract (CVE), mechanical ventilation with heat recovery (MVHR) or a fully automatic ventilation system (DemandFlow) requiring no user effort, Itho has a solution for every code level – and every budget. There’s also Itho’s leading Advance – so efficient it led to the creation of a new SAP Appendix Q category – and Itho’s unique range of HR cooker hoods.
