Air in my place can give me allergy, it’s mainly from my room, so what I only need is a purifier that works for about 300 sq. ft., but of course I want one that really works well, I know there is one kind that you don’t have to replace the filter, and it  seems like it is really easy to use. Then I found the best purifier that has  different kinds of air cleaner. By this purifier, I can now breath nice air and be allergy free.
