Get a nasal sprayer and ultrasonic nebulizer. That's what I did for my wife! Since she has had these -she uses the nasal sprayer as she feels - filled with CS( Colloidal Silver ), She uses the nebulizer with CS when she thinks/feels/see's that she has an infection starting. If my wife gets an upper resp infection she ends up in the ER or in ICU. So the CS has kept her out of the hosiptal for over two years!! I also use it if I feel something cold/flu comming on. You can get an ultrasonic nebulizer from flea bay that runs on 12VDC. The nasal sprayer can be bought on several sites.
