Atmospheric pollution
An air pollutant is a substance in the air that can have a harmful effect on humans and the ecosystem.
Health effects of indoor air pollution
Exposure to indoor air pollution has been linked to the development of all types of illnesses, from simple infections to lung cancer and asthma. It can also cause less serious side effects, such as headaches, nasal congestion, nausea, fatigue, and dry eyes. If you already have a lung condition, you run the risk of your symptoms getting worse.
Poor indoor air quality and its causes
Particles related to air pollution can take the form of solids, liquid droplets or gases. Excess particles can accumulate indoors with insufficient ventilation, high temperature or unfavorable humidity levels. In some cases, ventilation may be difficult. Indeed, the levels of indoor pollutants are likely to increase if the quantity of outdoor air brought in is insufficient to dilute the indoor air, but also when outdoor pollutants enter the indoor air and become trapped there.
Health impacts of poor indoor air quality
The American Lung Association's annual 'State of the Air' report says half of Americans still live in counties with clearly harmful levels of ozone or particulate air pollution. The 15th annual national report shows that while, overall, the reduction in particulate pollution continues nationwide, poor air quality remains a major public health concern. One of the major reasons for concern is the increase in ozone (smog) levels, which have progressed since last year's report and remain one of the most potent respiratory irritants and most prevalent air pollutants. in the world.
Key findings from the 2014 State of the Air report:
Nearly half of the people in the United States (147.6 million) live in counties with unhealthy levels of ozone or particulate pollution.
In the United States, more than 27.8 million people (or 8.9% of the population) live in 17 counties whose various levels of the pollutants measured in the report are considered harmful.
In twenty-two of the 25 cities listed in the 2014 report (including Los Angeles, New York and Chicago) as being most affected by ozone pollution, the average number of days when peak ozone was recorded was higher than in 2013.
Conversely, thirteen of the 25 cities known for their alarming annual particulate pollution levels, including Los Angeles, Atlanta, Pittsburgh, and Bakersfield, showed improvement and had their lowest levels.
Who is most at risk:
Infants, children, and the elderly
people with lung diseases such as asthma and COPD
people with heart disease or diabetes
low-income people
people who work or spend a lot of time outdoors
Dangerous levels of air pollution can cause wheezing, coughing, asthma attacks, heart attacks and even premature death.
The balance between indoor and outdoor air
Your best defense against indoor air pollution is to avoid bringing pollutants into your home or office as much as possible. This is what the American Lung Association calls source control. Creating a well-ventilated space that allows fresh, clean air to flow is a good start to keeping your indoor air free from outdoor pollutants. A suitable air purifier can help, but it remains preferable to avoid, upstream, the pollution of indoor air by outdoor air.
Air purifier to fight pollution
If your home or office is prone to indoor air pollution, an air purifier can be helpful in removing harmful particles and improving your air quality. In a house with a high level of particle pollution, such as exhaust gases, dust, and bacteria, the use of a Blueair particle filter is recommended. In a home or office overrun with heavy gaseous pollutants, such as VOCs and smoke, a SmokeStop™ filter is recommended. You could find more information about product air purifier here
When to change the filters of an air purifier?
This criterion depends on the use you make of your air purifier. The more the device operates during the day, the more dirt it will filter and therefore the faster the filters will wear out. On average, it takes between 4 and 6 months before you have to change the filter of your air purifier.
What features should you consider when choosing an air purifier?
An air purifier has features that differ from one model to another. Find below the characteristics to take into account when choosing your air purifier:
The filter system
The filtration system is an essential point when choosing the purifier. Your purifier must be equipped with 3 or 4 levels of purification:
a pre-filter: this pre-filter retains large particles of dust, hair and hair, which will avoid clogging up the following filter levels too quickly;
a HEPA filter: the HEPA filter will allow you to capture fine particles suspended in the air;
an activated carbon filter: this filter allows you to retain gases, volatile organic compounds and odors;
a UV filter: this filter removes all viruses, germs and bacteria.
The maintenance cost of the air purifier and its filters
When you buy an air purifier it is necessary to know the maintenance measures to put in place: the filters are the elements of the purifier that require the most maintenance. It is therefore necessary, for the proper functioning of the purifier, to ensure that the filters are always clean.
The choice of the model according to the room
It is essential to choose the model of the purifier according to the dimensions of the room. It is recommended to choose the model above the size of your room in order to maximize its efficiency.
The sound of the turbine
A purifier is motorized and therefore generates noise. These noises can cause annoyance especially when the purifier is placed in an office where concentration is necessary.
Where should I put my air purifier?
A purifier can be placed in any room where there is a need to purify the ambient air. In order to obtain the best results, the air purifier should be placed in a strategic location: near a source of pollution and ensure that the device does not interact with other devices.
