Riverdale, Nov. 28, 2021 (GLOBE NEWSWIRE) - In today’s eco-conscious atmosphere, it is difficult to find people who do not understand the dangers of breathing polluted air, whether it is chemical fumes from manufacturing plants, wildfire smoke, car exhaust, or nearby buildings The airborne fiber material at the construction site. Everyone knows that polluted air is bad; this is why there are air filters in homes, businesses, hospitals, and indoor gathering places.
But according to new research from Washington State University, some of the most harmful forms of air pollution do not come from where most of us might think. Although there is no doubt that outdoor air quality plays an important role in our overall health, the real threat to indoor air quality (IAQ) is likely to come from items that already exist indoors.
"WSU researchers found," Camfil USA marketing and technical materials manager Mark Davidson explained, "In ordinary American homes and facilities, the levels of pollutants are surprisingly high, including highly toxic substances such as mercury and formaldehyde. Will be expected."
For clean air experts like Camfil USA and the wider American public, the survey results reveal a surprising fact, namely the importance of air filtration and IAQ.
WSU research supports the relationship between external temperature and internal air quality
Researchers set out to study how formaldehyde emissions increase or decrease throughout the day, using selected real American households to protect data. Their most direct discovery is that the emission level increases with the increase in indoor temperature. In some cases, for every 1 degree (C) increase in temperature, the emission level can reach up to five parts per billion.
"Over time, houses have become hotter and hotter, and chemical emissions have increased." Davidson continued. “Researchers’ work has shown that although modern HVAC systems can maintain comfort, the temperature will still rise, and the air filtration components of these systems may not be configured to deal with chemicals emitted by new houses.”
How gypsum wallboard threatens indoor air quality
One of the most surprising findings in the WSU study is that there may be a correlation between the presence of gypsum wallboard in the home and high levels of formaldehyde and mercury emissions. Although this is just a premonition, the researchers took samples of wall panels from the house and heated them in the laboratory, and found that the hotter the wall panels became, the more formaldehyde emissions were detected.
The implication here is that warm days may be enough to increase the chemical emission levels of materials and furniture, not to mention radiation and floor heating.
The most effective indoor air pollution solution
One solution that is becoming more and more popular worldwide is a portable indoor air purifier. These compact particulate and molecular air filtration devices are designed to be used where needed, independent of the air filters in the central HVAC system, and provide effective indoor air quality reduction.
City M air purifier is a typical example of a portable indoor air purifier. It can not only suck out dust and particles in the air (in the process to keep the room clean), but also provide much-needed symptom relief. Caused by the presence of certain chemicals in the air supply of a home or facility.
Why cheap air purifiers are not as effective as they need
Since exposure to chemicals and neurotoxicity in the air is directly related to cognitive impairment, such as reduced thinking and learning ability, home buyers, construction operators, or builders must spend time researching new construction projects of the type of materials that are about to enter. This is especially true when children may live in a facility.
Not all air purifiers are designed to remove particles and chemicals from the air. It requires two different styles of air filters; one is specifically designed to remove particles, usually a HEPA filter, and the other is a so-called molecular filter, sometimes also called a carbon air filter.
The HEPA filter should be tested and certified to prove that it can remove at least 99.995% of particles larger than 0.3 microns. Many air filters are marked as HEPA or advertised as true HEPA, but unless the manufacturer can provide a complete test report to prove the filtration efficiency for 0.3 micron particles, the air filter should not be considered HEPA. If the air purifier contains a molecular or carbon air filter, it should be verified in accordance with ISO 10121 or ASHRAE 145.2.
Spending money on an air purifier cannot prove that its performance is equivalent to these basic performance standards. This may mean that the product purchased is essentially just a very expensive fan that moves the air but cannot purify the air.
Air filter replacement: How often should I replace the air filter?
Asking how often the air filter should be replaced is like asking how often the lawn should be trimmed; it depends on rainfall, weather, and time of year. For HEPA air filters, it depends on the actual efficiency of the air filter (99.995%), the volume of media in the filter and the dust load. Generally speaking, the HEPA air filter in the air purifier can be used for at least 18 months. Air purifiers that guarantee a 5-year or 10-year service life should be carefully evaluated, as this is problematic in a typical environment.
