“…For this strategy, the toxic gases are removed also by AC particles, which are fixed by adhesive onto the back of the filter materials. [ 50 ] The third strategy is called source interception, which capture the toxic gases from the top of the surface. This is attractive as it can effectively control the VOCs releasing at the first place.…”

Functionalization of polymer foams by surface coating is of great interest for advanced flow‐interactive materials working with well‐controlled 3D open channels. However, realizing heavy functional coating via a fast and recyclable way remains a big challenge. Here, inspired by the battery electrodes, we propose a scalable mechanic‐assisted heavy coating strategy based on the design of sticky jammed fluid (SJF) to conquer the above challenge. Similar to the electrode slurry, the SJF is dominated by a high concentration of active material (≥20 wt% of active carbon, for instance) uniformly dispersed in a protein binder solution. Due to the sticky and solid‐rich nature of the SJF, one can realize a high coating efficiency of 60 wt% gain per coating. The critical factors controlling the coating processing and quality are further identified and discussed. Furthermore, the functionalized foam is demonstrated as a high‐performance shape‐customizable toxic gas remover, which can absorb formaldehyde very efficiently at different circumstances, including static adsorption, flow‐based filtration, and source interception. Finally, the foam skeleton and the active materials are easily recycled by a facile solvent treatment. This study may inspire new scalable way for fast, heavy, and customizable functionalization of polymeric foams.

“…The result of this study revealed that despite the significant retention of pets' allergens present in the air, effectiveness of air purifiers used was negligible on asthmatic therapy. Another study compared the effectiveness of PM and Volatile Organic Compound (VOC) removal by several home air purifiers with different technologies (Berne P, 2019). The study concluded that air cleaners under showed effective removal of PMs over VOCs.…”

Background: A set of environmental preventive measures involving ventilation control within healthcare facilities is well established. Portable air purifiers have been introduced in recent years as one of alternative technologies used to prevent infection and other respiratory complications in indoor environment. Objective: To asses indoor air quality in pediatric intensive care units at two tertiary hospitals in Riyadh, Saudi Arabia in the presence and absence of portable air purifiers.Method: Fine particles (PM 2.5) and coarse particles (PM10) were obtained using optical particle counter and microbial counts were obtained using Andersen air sampler from outdoor and two patient rooms in pediatric intensive care units. Pollutants levels reduction between outdoor and indoor were calculated and compared using Statistical Package for the Social Sciences software (SPSS Version 27.0. Armonk, NY: IBM Corp) were utilized for statistical analysis. Results: In hospital A and B, non-protective environment room (NPE) had a significantly higher number of fine particles and total bacterial count (TBC) respectively than semi-protective environment room (SPE). Meanwhile, there was significantly higher reductions of fine particles (hospital A) and coarse particles, fine particles and TBC (hospital B) in SPE rooms compared with NPE room. Hospital-A had significantly higher reduction efficacy compared with matched rooms in hospital-B for fine particles, coarse particles, and TBC. Conclusion: This study demonstrated that portable air purifiers have a great impact in the reduction of indoor air pollutants in PICUs including fine particulate matters and TBC in particular. Furthermore, ventilation systems equipped with HEPA filters along with portable air purifiers significantly reduce the levels indoor air pollutants of outdoor sources. Moreover, this study showed that newer and well-maintained HVAC systems play a significant role in controlling the levels of airborne pollutants.
