The health care system presents a complex set of environments, with a multiplicity of demanding filtration requirements. Choosing the right filtration system is of critical importance. Waco has over 40 years experience dealing with the filtration requirements of hospitals, clinics, and other health related facilities. The company has a wide variety of filtration products hospitals need to provide an environment thatâ€™s safer and healthier for both patients and hospital employees. Listed below are some of the unhealthful conditions which are addressed by Waco filters:
An operating room or laboratory may be loaded with bacteria even though they appear to be clean. The number of bacteria depends on several factors. Broadly speaking, any indoor space contains a concentration of airborne bacteria that results from the balance between the bacteria released by occupants and the rate of removal by the ventilation-filtration system. If the hospital uses recirculating systems, bacteria must be removed before they reenter the hospital.
Plants release pollen grains as part of the plant reproductive process. Although pollen is not truly pathogenic, it can cause allergic reactions such as eye irritation, sinus inflammation, and asthma. Pollen grains are one of the reproductive cells of plants. Because most pollen grains exceed 15 micrometers in size, it is quite easy to remove pollen from the air with the right filtration media.
Normally dust is not considered a pathogen at moderate levels. It is comprised of soil particles, soot and organic debris. However, dust particles can serve as carriers and sources of nutrition for microorganisms.
Fungi are a serious air pollution concern because they produce airborne spores as part of the reproduction process. There are many hundreds of organisms that are considered fungi and almost all of them are considered allergens. A few fungi can cause serious infection or even death. Fungal spores can be broken down into two categories:
Yeasts remain spherical during reproduction and form colonies of round cells.
Molds reproduce by means of a "mycelium". The gray fuzzy clumps seen on decaying food are an example of mycelium.
Viruses are so small (less than 0.1 micrometer) that filters do not reliably remove them from the air. The best filters for viral capture are HEPA filters but even they are not totally reliable.
