Pooling our resources – saving together! For homeowners’ associations, we offer exclusive terms on purchasing air filters.
In most countries, resident associations are responsible for maintaining all building services to ensure flawless operation – and servicing ventilation systems is no exception. By collaborating, associations secure better terms from suppliers and contractors.

❓ Did you know many heat-recovery unit manufacturers use exactly the same filters as we do? ❓
Most manufacturers don’t operate their own filter production lines and instead source air filters from third-party suppliers. That means our filters are often identical to the originals — but at a better price. 📦✨
