You need to put pure water in a clean container and then process it in some way to eliminate bacterial contamination. You can process the water with heat just like you do when canning, or use a chemical like chlorine or iodine.
That said, from what you are describing several causes come to mind. They are deviated septum, vasomotor rhinitis or nasal polyps. It sounds like you might have a nasal polyp on the right side of your nose. A nasal polyp is noncancerous, sac-like over-growth of inflamed tissue lining the nose or sinuses that can block nasal airway. Since it is the same side all the time, you might also have a deviated septum that occurs when the thin wall between your nostrils is displaced to one side, making one nasal passage smaller.
If you have frequent nosebleeds, you could have a more serious problem. Dry air is the most common cause of nosebleeds. Living in a dry climate and using a central heating system can dry out the nasal membranes, which are tissues inside the nose.This dryness causes crusting inside the nose.Crusting may itch or become irritated.requent nose blowing is another cause of nosebleeds. Other common causes of nosebleeds include: 1  foreign object stuck in the nose. 2  chemical irritants. 3  allergic reaction. 4  injury to the nose. 5  repeated sneezing. 6  picking the nose.
