The use of saline (salt water) irrigations for the nose and sinuses has been shown to be highly effective in improving allergy symptoms and shortening the duration of a sinus infection. Typically, for allergy sufferers, I recommend irrigating the sinuses once every day to every other day with 8 oz of salt water. As there are some data indicating the over irrigating the sinuses can deplete natural immune cells that reside in the mucus of the sinuses, I would not recommend irrigating more than once a day.
