One day , the power go out while i was sleeping. I woke up the subsequent morning coughing up blood, because the filters be Off! They help so much. Good luck, permit me know how it goes. I own allergies and severe asthma.
I've used a HEPA filter without much nouns. Spoke to my allergist who said most aren't worth the money, best option is to use your internal A/C/heat and a good 3M allergy filter that's changed frequently. He said not to bother next to the "ionic" cleaners, they don't actually do much except collect dust equal way your TV does. Hopefully you haven't already spent big $$ on one already! He have some paperwork printed from Consumer Reports, you might check them out if you really want to try one. Good luck!
