Chad, please oh please read the document Stan suggests as it really is knowledge you need to have to prevent serious health problems that can creep up on one without you noticing. The quote below gives the gutze of the article.
Fine dust harms everyone exposed and toxic dust can blindside us quickly. A Google search on PM health risks shows over seventy seven million references. Although these references contain considerable nonsense, the peer reviewed medical research shows every exposure to fine dust causes a measurable loss of respiratory function, some of this loss becomes permanent, and the higher and longer the exposure, the greater the damage. After I installed the top magazine rated cyclone system with upgraded fine filter fine wood dust blindsided me. Like most other small shop dust collection solutions my cyclone created a bad false sense of security. It left a clean looking shop while building dangerously high levels of invisible fine dust. I had no warning or clue that my shop and attached home were dangerously contaminated. Poisonous chemicals in wood cause a range of toxic reactions including irritation, chronic infections, wood related diseases, worsening allergic reactions, nerve damage, poisoning, and even increase our risk of cancer. Less than three months after installing this cyclone a worsening allergic reaction landed me in the hospital, cost 58% of my respiratory capacity, and left me still supplemental oxygen dependent over a decade later. Certified air quality testing three months after I stopped woodworking showed my shop and home contaminated with wood dust particle counts thousands of times higher than considered safe. Many now monitor their own air quality using affordable 0.5-micron Pro Dylos Particle Meters. They consistently find similar problems with almost every dust collector and cyclone system vented inside regardless of fine filter upgrades and vendor advertizing claims. Many report their clean looking shops contain so much fine invisible dust just walking around launches dangerously unhealthy amounts airborne. Many found their meters clearly show when a dog or cat walks through their clean looking shops at night. Sadly, I get about two emails a week from others blindsided by fine dust allergic reactions that forced them to either totally quit woodworking or stop working certain woods.
