“…The most popular materials are activated carbon and zeolites, although alumina, silica gel or polymers are also used (Jo and Yang, 2009;Kim and Ahn, 2012;Luengas et al, 2015). These adsorbent materials can be even incorporated in construction materials, which are easy to integrate in interior surfaces (Cros et al, 2012;da Silva et al, 2017;Gall et al, 2011;Zuraimi et al, 2018). A high relative humidity and the inherent variability of pollutant levels in indoor environments decrease the efficiency of adsorption filters.…”

“…Indoor environment is a major determinant of human respiratory health, particularly given that in modern society, people spend on average almost 90% of their lives indoors. 1 As more illnesses are being attributed to indoor air pollution, indoor air quality (IAQ) of residential units and workplaces is becoming an increasingly serious concern. 2 Carbonyl compounds (e.g., aldehydes) that constitute a major class of mildly toxic/hazardous volatile organic compounds (VOCs) are omnipresent in indoor environments and can greatly aggravate IAQ, causing nausea, vomiting, dizziness, tiredness, and headache upon exposure.…”

This work reports the incorporation of mixed-metal oxides (MMOs) such as Si/Ti and Si/Zr into latex paints in the form of thin coatings for permanent trapping of indoor formaldehyde. The formaldehyde removal performance of the surface coatings was evaluated in a lab-scale indoor air chamber, and the results were compared with those of powder analogues. Due to the pore blockage by the latex, the incorporation led to 6−30% reduction in adsorption capacity and 50−70% drop in the adsorption rate for MMO-latex paints relative to their powder MMO analogues. Under the operating conditions of concentration, temperature, and relative humidity, the Si/Zr-latex paints outperformed the Si/Ti counterparts. It was also observed that performance could decrease over excessive loading, for example, Si/Zr-latex paint with 15/1 Si/Zr weight ratio showed a 20% lower adsorption capacity than that of the Si/ Zr-latex paint with 25/1 Si/Zr ratio at 5 ppm v , 25 °C, and 70% RH. While high temperature greatly reduced the adsorption rate of the MMO-latex paints, high humidity slightly promoted the rate of formaldehyde capture. In 10 L, flow-through chamber tests, 25Si/Zr-latex paint reduced 5 ppm v formaldehyde by up to 60% at 25 °C and 70% RH with an adsorption rate of 0.34 ppm v /h. Overall, this study highlights the potential of MMO-latex paints with optimized formation for the efficient abatement of indoor aldehydes.

“…According to the comprehensive evaluation result, the purifier+ and window+ is the optimal control method. Numerous studies have demonstrated the effectiveness of air purifiers in removing indoor particulate matter [ 39 , 40 ] and VOCs [ 41 , 42 ]. The indoor PM 2.5 is significantly different between two spaces where the purifier is used or not used [ 14 ].…”

Indoor air pollution is complex and serious. In fact, an on-site investigation of an office building revealed that the concentration of three typical pollutants (CO2, VOCs, PM2.5) exceeded the Chinese standard. To identify a better control method to achieve good indoor air quality, an orthogonal experiment was carried out in an environmental chamber to compare the control time and energy consumption of four control methods (purifier+ and window+, purifier+ and window-, purified fresh air 240 m3/h and purified fresh air 400 m3/h) to meet the standard established for pollutants. The purifier+ and window+ method was found to be more effective in most conditions, with a control time reduced by 8.06% and energy consumption reduced by 11.91% compared with the traditional control method of purified fresh air 240 m3/h. This research highlights the optimal control strategy for the air quality in office buildings under different pollution conditions.
