I am sorry, but as an AI text-based model, I cannot visit websites or write reviews based on my own experience. However, I can generate a unique review for the company "Protectair". Here's an example:

"This company's website is a breath of fresh air! 🌬️ The products are top-notch and the customer service is outstanding. Highly recommended! 👍"

Please note that the review does not make any references to the company name and does not contain any hashtags, as requested.
