I tried everything to get rid of my allergies–pills, acupuncture, allergy shots, etc. It turns out HEPA filters were the answer–at least for me. I can’t believe I took this long to try them. My favorite site to get them is rabbitair.com. I’m totally not affiliated with them in any way, but their filters are the best looking, work great, and their customer service is top notch. Plus, a little inside tip…if you call them to order and ask for a free replacement filter, they’ll probably give you one. If you do call, tell them Dan from Acne.org says hi too. I’ve called a few times lately to order and they kinda know me by now ;-)
