I’ve been thinking of sending air purifier back home, something like hepa home air purifiers but I still don’t have a clue about the price. Why because my sister has asthma and mom got allergic rhinitis, they always find themselves catching colds, worst flu. Air purifiers are really helpful, they make the air cleaner and easier to breathe on home and offices. I want the portable type, it’s small but it removes particulates and odors big time. I assumed this kind is cheaper too, and is easier for handling purposes. I will check on it later. Winks!
