My son has allergic rhinitis. It gets aggrevated when he gets exposed to dust or a dusty environment. But because of technological advancement, more and more things that can make people's lives easier are getting invented each day. Gone are the days when we still have to rack our brains how to install a security camera, there are now brands that offer wireless security cameras.
And people suffering from allergies need not worry about dust from electric fans anymore because bladeless fans are now available in the market. Since its fairly new, it is still very expensive. I first saw it on a deal site, still hard on the pocket even when it's already on sale. Maybe when the hype about it has subsided, it will be more affordable.
