I had bags like this back in college and I remember they had a lot more padding and were very well made around the To filter air and capture particles etc. Now these bags are paper thin. I'm not sure if this is the result of better technology or if they're just made very cheaply now. I've lost confidence in them as they are nothing like the ones that came with the vacuum. I think the only sure way to know if you have an allergy is if this bag is important to you then you know for sure. Sorry I can't give better information than this.
