What am I allergic to in my own home?!

What am I allergic to in my own home?

I consider myself to be an intelligent individual, however, I have no idea what is causing my allergies to act up mainly when I am at home. I live in an apartment in an urban environment. I clean. I dust almost everyday or so it seems...yet my allergies acts up the majority of the time only when I am at home.

During the months of August-April, I am gone 14-16 hrs of the day so I am not at home that much and my allergies do not effect me that much...but when I am home from April-July, when I am home everyday, they wreak havoc on me. I also realize that is springtime...hence more pollen.

I have tried various types of air filters..with no luck. Needless to say, my medicine cabinet has much benadryl.

What am I missing that could cause my allergies to flare up when I am at home? Is there a specific type of air filter I should buy? What are some suggestions?

My sister in law had the same problem except she had headaches. they removed all the carpet in their home an put down hardwood flooring. Her headaches immediately stopped. The carpet eventhough it was clean trapps lots of dirt an allergens under it and in it. If you dont want to remove your carpet try having it professionally cleaned
