I absolutely LOVE this filter!! I had it on medium level while I used to be sleeping and awakened without a sore throat! My nose felt much clearer, although still a touch congested, but clear enough to the purpose that I could still breathe through it. I highly recommend this filter to anyone suffering allergies this season.
