This category refers to particles that are often thought of as dust, but are often combinations of Dirt, Dust, Dead Skin, Pollen, Building materials and Smoke. Particulate are considered inert, meaning not alive, but living organisms like dust mites can live on those particles. During the course of a year, the average home accumulates approximately 40 lbs of household particulate.
Inert particulate alone usually cause the least amount of health problems, but for some, may become a severe irritant, causing reactions or life threatening illnesses such as cancer and heart disease. An example would be asbestos or cigarette smoke. Most basic HVAC filters are inadequate to cope with the many different sizes and types of particulate.
Heavier particulate is usually removed by vacuuming and dusting. Lighter migratory particulate or dust can be removed by portable or fixed filtration systems. Particulate of under 2.5 microns can infiltrate the lining of our lungs.
Filters are great and a necessity of an airflow system in just about every home. However, (Filtration Alone is Inadequate) to address other airborne agents that are potentially more harmful. Many microscopic organisms can flow through some of the best filters, as do chemicals and viruses (see chart below, HEPA limit is in RED).
Although airborne living organisms (bioaerosols) are often referred to as particulate when determining the total suspended particulate (TSP) or respirable suspended particulate in a building, we have separated this classification into it's own category for explanatory purposes.
Second Wind offers several options for filtration in its All-In-One Solutions for your home. Please see our products section and look at the 9000 & 9200 series.
