You've taken Claritin but you're still sneezing. Hmm, maybe it's not from pollen, maybe it's from dust all over your house. I know, I haven't thought of that too but I read that it can trigger allergies. That's why I vacuum the beds, yes, I do. I also read that tip somewhere. It sounds weird but it does make sense. I also use pillow covers, it's not pillow cases. It's a cover for your pillow and protects it from sweat and dead skin cells. I also wash that once a week with the sheets. When I vacuum, I vacuum the walls too, using the brush attachment. Along with that, in the bathroom, I also vacuum the bathroom fans and all the doors. You know those noooks and crannies, vacuum really does the job. You can wipe it if you want but I find the vacuum much more efficient, unless the dirt has been there forever and you can't take it off, then you need a heavy duty cleaner and a rag. So it is a good idea to vacuum regularly to keep dust at bay, especially if you have a household member who has allergies.
