"I just wanted to put pen to paper to confirm how good the portable air sterile unit is. As a high-end boutique hotel it is extremely important for us to maintain high hygiene standards throughout the property, and the unit really helps us to achieve this. I must admit I was a bit sceptical at first, but it’s really proved its worth – it helps to remove odours from bedrooms where guests have smoked, or we have painted the room, or there has been an accident – instead of keeping the room off, we can re-instate it much quicker and sell it – it pays for itself! I am really impressed with it – thanks for convincing me!"
