If there seems to be a continual problem for someone with coughing, sneezing or watery eyes - it could be that you need to investigate fitting some fine dust filters. Fitting fine dust filters can help prevent what can start off as a minor complaint or irritation - developing into a more serious health related issue such as asthma or worse. A dust particle is defined as one that is less than 500 microns in diameter. That means it is less than 500 millionths of a meter in diameter - which individually would be invisible to the naked eye. However, fine dust particles can be as small as one billionth of a meter in diameter, such nano particles can pass through many normal dust filters, which is why specially manufactured fine dust filters should be used.
Of course there is no one source from which fine dust comes from; in fact a bewildering number of things can generate fine dust, and just to add to the confusion another term for fine dust is an aerosol! So, despite often thinking of dust as only being a solid, in fact the term fine dust can also be applied to droplets of liquids. Generally speaking most people accept that dust is minute particles of human skin, earth, plant pollen, or textile and plant fibers that in some way have been shed from their carrier. Quite rightly this leads people into not being too concerned about dust in their home environment, and it never passes our minds that we ought to fit fine dust filters. After all this sort of dust has been around for some time now, but has not done any lasting harm to the human race. That is, of course, true, but in modern times there are many other less natural fine dust particles in the air that have to be treated as pollutants and really should be removed by fine dust filters. Such fine dust particles include: metals and soot not to mention a host of chemical fine dust particles that can be released from the humblest printer toner cartridge through to even slightly radioactive dust - if something like a microwave oven has been incorrectly discarded or damaged.
Our bodies do have natural defense mechanisms against dust getting into our bodies. When breathing through the nose we have a natural filtering system and our respiratory tract has many devices to trap other dust particles. However, fine dust particles are capable of penetrating deep into your lungs, and can then even enter your bloodstream. The only way of preventing this risk, which can lead to all manner of serious illnesses is by having effective fine dust filters to remove such particles from the air. Breathing in toner cartridge dust is one thing, having it enter your blood stream and being a potential cause of cancer is quite another. Fortunately, there are many fine dust filters available over the internet that can be used to either prevent fine dust from entering the air in a room or that can filter all of the air in a room. For example to reduce the risk of toner cartridge dust entering the air in a room you can fit toner cartridge fine dust filters from micronAir Office.
