The list below includes woods whose dust has been identified as being toxic as well as what reactions they illicit and their potency.

Most woodworkers know that dust is a major nuisance in the shop. But how many realize that excessive exposure to wood dust poses a health risk as well?
Frequent exposure to large amounts of wood dust can lead to sinus and lung problems, or worse. And it's the finer dust particles - those smaller than 10 microns - that are the most hazardous. To put that size in perspective, consider that a human hair is about 100 microns thick, while airborne dust particles smaller than 20 microns are invisible to the naked eye.
Wood dust is known to be a human carcinogen…
On December 11th of 2002, wood dust was added to the federal government's list of compounds known to cause cancer in humans. The report is issued every two years by the National Toxicology Program, a division of the U.S. Department of Health and Human Services.

Our lungs have a built-in cleaning system that works efficiently under most conditions to protect delicate tissues from the damage fine dust causes. The trouble starts when your respiratory system must deal with large amounts of "respirable dust" (below 10 microns in size). Heavy exposure to this dust can overwhelm the lung's natural defenses and lead to inflammation and swelling of the airways, which cause symptoms such as shortness of breath, increased sputum and coughing, frequent colds, nosebleeds, sinus trouble, or bronchitis.
Also, wood dust may contain allergens and toxins such as pesticides, fungi (molds), and chemicals which can trigger allergic reactions. Many tropical hardwoods can be especially irritating, and Western red cedar can cause allergic asthma.
Our filters are 3rd party tested. For additional documentation we have our filters sent to accredited ASHRAE test labs.
Our HEPA and Spunbond Filters have no internal obstructions to interfere with cleaning and have a Teflon-like coating to facilitate easy dust release by blowing on the outside of the filter with compressed air. Internal cages and wire supports can trap dust and chips making filters almost impossible to clean.
Please Note: Even with the best filter system, Oneida Air recommends always wearing an OSHA approved NIOSH mask when working with airborne wood dust. For more information see www.cdc.gov/niosh
