I often use nasal sprays with salt solution to help clear my nasal passages when I have colds or bouts of allergic rhinitis (like now, arrrgh!!!). But I just received an email about SaltAire Nasal Wash and wondered if they're any better than the other generic salt solutions I get from the drugstore. From their website:

Now available over-the-counter at drug stores across the nation, SaltAire Sinus Relief gently washes away dust, mold and pollens as well as the other inhaled allergens and pollutants that can cause nasal congestion, allergies and sinus infection. SaltAire's smooth, non-irritating formula and its award-winning, patented dispenser make nasal cleansing pleasant and quick, taking less than a minute each day.

Has anybody used them? Would appreciate feedback!
