Air Purifiers

My chest really hurts. My landlord had cleaned the mold problem in my room. But I find it hard to breathe in there. But I also went a little crazy cleaning with chemicals such as tilex, a great value disinfectant, and I sprayed perfume because I still smelt mold. I haven’t cleaned the carpet yet or my stuffed animals, could the chemicals and my stuff be the reason why I can’t breathe well? Or is the mold in the walls?
I also have an air purifier with a hepa filter, should I change the filter?
It really hurts to breathe and Ive been in my moms room for now, but I really want to go back to my room.
I have the door open and a fan
still no hope

I live in an older house (about 1100 sq. ft.). We have a terrible mold problem. I’ve been using a HEPA system, but the filters are .00 each, and it takes three of them. I’m interested in hearing from anyone who has experience with the Ionic Pro Turbo air purifier, as to how well it performs, or what is the best, affordable, air purification system.
In the meanwhile, I think I found a better solution. I bought two 20 inch, square, window fans (.85 each). Then, I bought two 20X20 3M Ultra Allergen Filterete furnace filters (.75 each), and simply put them on the back side of the fan.

Man, does it ever filter. It puts out a lot of air, and the filters catch allergenic particles such as mold, and even smoke. So far, it works great. And it sure beats paying 0, for an air purifier, (which is basically just a fan with an allergenic furnace type filter on it anyway), and .00 for replacement filters!
