As long as there is water, many organisms can survive. For example, some fungi and bugs. So eliminating the moisture can kill any fungus that may already be present and will prevent fungal attacks in the future as long as the wood remains dry. Properly drying the wood also kills any insects and eggs that may be in the wood. Most insects require moisture content above 10% in order to survive in the wood. This is why the wood used to make furniture must be dried. The moisture content of wood used to make furniture is generally 6%-8%.

Timber can be dried to any desired low moisture content by conventional or solar kiln drying, but in air drying, moisture contents of less than 18% are difficult to attain for most locations. The inside of the wood cannot be fully dried, and there is still a risk of insect eggs eating into the wood.

Using a high frequency vacuum wood drying machine, you can use high frequency heating technology to dry from the inside out, forcing out moisture and allowing the wood to be thoroughly dried.
