Has anyone used a UV light for killing dust mites, viruses, and bacteria to help alleviate allergies

My 2 1/2 year old daughter has terrible allergies, she has been suffering since she was 5 months old. She had 12 sinus infections and 3 ear infections in her first 2 years alone. We started her on Flonase 6 months ago, which really helped teh infections, but since September 1st she has had a lot of congestion again, and has been coughing for at least 2 hours each night due to drainage. We had a Sharper Image UV air purifier, but it has broken 2 weeks ago and we are getting it replaced, not having the unit may be making her allergies worse, we are not sure. We tried Claritin syrup for the past 2 weeks but it does not agree with her stomach. Would a portable UV lamp wand help with some of her symptoms? Has anyone tried the UV wands for dust mites, bacteria, and viruses? The one I see on-line costs nearly $300, would a small aquarium UV light work in the same way for a lot less? ($50?) What is your opinion on UV light alleviating dust mite allergies, do you think it is worth it?

Your daughter would benefit more from a regular HEPA air purifier. The Sharper Image ones are better than none at all, but they do not do the job that a normal air purifier does. There is no substitute for one as you are finding out. It does not take dust, pollen, danders out of the air like a HEPA does. If you're ready to spend $300. on her health, it would be a good idea if you purchase a HEPA air purifier as they are the only ones that would be able to help her breathing.
