This sounds like advertising to me.
Has bumped up an old post and recommended 'IQAir air purifier in the Asthma Magazine'. Their profile includes a website AllergyCosmos.co.uk which if I remember correctly is a no-no like including email addresses? On first look, I suspect this may be bordering on advertising commercial products or services. Profile also says Likes/Dislikes: Non medical asthma and allergy relief solutions.
Haven't looked any further at this time of night after a rather erm interesting day but will look afresh tomorrow. What do you think in the meantime?
