My allergy symptoms have plagued me for years, and honestly I’ve tried every single thing that one could ever imagine. I’ve tried drugs, over the counter remedies, homeopathic remedies. You name it and I’ve tried it for sure. The only thing that has worked to this date is the Dyson DC25′s built in HEPA filter, which has almost completely irradiated my allergy symptoms and fixed the problem completely. I have to say that this is not only the best upright vacuum, but actually the best product overall for allergy symptom sufferers. I was never able to get through a night without waking up with nasal congestion and throat pain, but ever since I started vacuuming the room with the Dyson DC25, this rarely ever happens anymore and I can honestly say that I’ve finally found peace with my really bad symptoms. Please do yourself a favor and get yourself one of these, because you won’t regret it.
