Organic Cotton acts as a natural agent to filter out impurities giving you smoother inhalation. The use of Organic Cotton is very important as conventional cotton is treated with synthetically produced chemicals. To fully benefit from Scientific Inhalations’ breakthrough technology, you should only use Organic Cotton to filter your tobacco products. Each container of Organic Cotton holds approximately 60 cotton filters. In our tests with an Ultra glass filter, we have found that close to 15 inhalations work well before there is the need to change the cotton.
