The NOdA Gel odour neutraliser is a great new technology utilising sphere gel and a unique liquid formulation to give optimum performance. The product will not develop a crust on the surface as competitor products do, thus ensuring maximum delivery over its life span. Its unique delivery system also offers subtle, even delivery over a longer time span than competitor products. NOdA Gels are consistent day after day and offer peace of mind in the battle against odour! Place in your target area for rapid deployment, you can use a fan over the product or place in an area of airflow such in a run of ducting. To maximise the level of odour control, simply expose more surface area of the gel. One way to do this is to decant small amounts of gel around the targeted area. For maximum even delivery, shake well throughout life span.
