You may easily clean up dust under the sofa and on the carpet, but it's hard to deal with dust suspended in the air. Inevitably, however, dust particles are suspended in the home air. If someone in your home is vulnerable to dust and you don't know which machine can solve the problem, the right air purifier will help.
The importance of concern for dust in the air.
Dust can irritate your eyes, nose or throat, especially if you have allergies, asthma or other respiratory problems, which is a problem. If your asthma or allergies are made worse by dust, you may have dust allergies. The worry for everyone is that tiny particles of dust often float in the air, and if they are small enough, they enter the lungs and cause health problems.
If the air perifiers is useful for removing dust?
The short answer is yes, most air purifiers on the market are designed to remove large dust particles from the air. Many feature mechanical filtration, which is a method of capturing pollutants on filters. Either the particles are meant to stick to the filter or be trapped within the filter fibers. You have probably heard of a mechanical filter called a HEPA filter, which is designed to trap particles in the air.
Mechanical filters are either pleated like HEPA or flat. Though they are too basic to be used in an air purifier, an example of a flat filter is a simple furnace filter or a filter in your HVAC system, which can trap a small amount of dust in the air (this is your basic throwaway or washable filter). A flat filter could also be electrostatically charged for greater “stickiness” to particles.
What can air purifier do?
An air purifier that features a mechanical filter like HEPA is “good” if it can capture tiny particles within the fibers of the filter. Dust particles usually range from 2.5 and 10 micrometers in size, though some fine particles could be even smaller. If 10 micrometers sounds big to you, this might change your mind–10 micrometers is less than the width of a human hair! Most important to remember is that dust can potentially be small enough to enter the lungs and may cause health problems.
An air purifier that features a HEPA or other mechanical filter is an acceptable option for dust particles. But there is the possibility that mold/bacteria can grow on the filter and be released back into the air. Also, you need to remember to change the filters once they become saturated.
When it comes to electrostatic air filters or ionizers, it is best to avoid them. They can potentially produce an air pollutant themselves in the process–ozone–which can be harmful to you and your family’s health. They may not be as efficient either as a mechanical filter would be.
There is a practical option that is to use a worth filter like HEPA filter, which is designed to remove dust in the air. But the precondition is that you need to chronic replace the filters when they load with particles. dust particles, which are often the root cause of allergies.
You should also be taking preventive measures to keep from tracking dust from the outside, like changing your clothes upon entering the house or wiping pets down before they enter as well. This can reduce the amount of outdoor particles that come inside, such as pollen and mold.
