The article considers the issues of the impact on the environment of the city of pneumatic transportation for the removal of municipal solid waste (MSW). The disadvantages of conventional collection and transportation of MSW (container-garbage truck) are indicated, the main of which is the release of greenhouse gases into the atmosphere of the city...

Rationale: Indoor particulate matter is associated with worse chronic obstructive pulmonary disease (COPD) outcomes. It remains unknown whether reductions of indoor pollutants improve respiratory morbidity. Objectives: To determine whether placement of active portable high-efficiency particulate air cleaners can improve respiratory morbidity in for...
A tower air filtration system was designed in which bead air filters (BAFs) were actively rotated by a fan motor to remove particulate matter (PM) or HCHO gas. Three types of BAF, hydrophilic, hydrophobic, and hybrid, were prepared and compared for the removal of PM and HCHO gas. A tower air filtration system loaded with hybrid BAFs purified 3.73 L...

Positive and negative ions (PAIs and NAIs, respectively) generated by air ionizers curb indoor spread of airborne pathogens through cellular oxidative damage. Thus, here, we asked whether ion exposure of Staphylococcus aureus and Escherichia coli bacteria—either plated on agar or trapped in air filters—would affect their viability and whether this ...

Exposure to particulate matter (PM) is a key public health issue, but effective intervention has not yet been established. A systematic literature review and meta-analysis has been conducted to assess the relationship between the use of air filters, one of the most commonly studied interventions, and respiratory outcomes in patients with chronic re...

The implementation of sustainable solutions for maintaining indoor air quality has become a particular concern to the building community. Research on green technologies for indoor air has highlighted the potential of active botanical biofiltration (ABB) systems, where the air is circulated through the plant root zone as well as the growing medium f...
Tématem bakalářské práce je mikrobiální kontaminace vzduchových filtrů v automobilových kabinových klimatizacích. Mikrobiální kontaminace byla zkoumána na vstupních a výstupních plochách celkem 21 vzduchových filtrů, které byly vyňaty z osobních automobilů při běžných údržbách po jednom roce provozu nebo ujetých 20 000 km. Na obou plochách filtrů b...
Particulate and gaseous air pollutants pose a threat to human health and contribute to climate change. By today, air filters, stationary and portable, are markedly improved and can often provide innocuous air pollution levels. After introducing the classification and standards on air filters, the influence of the processing route and its parameters...
Práce se zabývá teorií suspendovaných znečisťujících částic, zhodnocením využití přenosných čističek vzduchu a aktuálně používanými technologiemi. V praktické části informuje o výsledcích měření s čističkami Daikin MC 707 VM a Ionic Care Triton X6 v reálném prostředí, u kterých posuzuje vybrané výkonnostní stupně a zaměřuje se také na závislost úči...

With rising global concerns over the alarming levels of particulate pollution, a sustainable air quality management is the need of the hour. Air filtration research has gained momentum in recent years. However, the research perspective is still blinkered toward formulating new fiber systems for the energy-intensive electrospinning process to fabric...
