Medical-grade units hold a specified oxygen concentration across their full flow range; this one does not, and it should not be used to meet a prescription.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does \"demo model\" mean?\u003c\/strong\u003e\u003cbr\u003eIt is a working unit that has been used for demonstration rather than sold new. Ask us about its running hours and what cover applies before you order.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhy does the purity drop at higher flow?\u003c\/strong\u003e\u003cbr\u003eThe sieve beds inside have a fixed capacity. The faster you pull air through them, the less time they have to separate out the nitrogen, so concentration falls as litres per minute rise.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat maintenance does it need?\u003c\/strong\u003e\u003cbr\u003eRinse and dry the two front filters regularly.
