The primary factor with sinus problems and allergies is the change in mucus consistency. Thick mucus doesn't allow your cilia to do their job of removing bacteria and irritating particles from your nasal passages. Fortunately, nasal irrigation products like the SinuCleanse Neti Pot Nasal Wash System can successfully ease sinus symptoms by thinning out the mucus, especially when it's dry or crusty. In addition, research confirms that antibiotic treatments and products like the SinuCleanse Squeeze Nasal Bottle Wash are highly effective in fighting sinus infections.
