Most of the air filters used in residential buildings have fibers with a permanent electrostatic charge, which allows them to capture airborne particles much more efficiently without restricting airflow
English
The particle removal effectiveness of electrostatic air filters may reduce by up to 95% and 75% after they are loaded w/ smoke and dust, respectively.
-- Replace air filters after high-polluted events e.g., wildfire smoke

“Covid is caused by a virus spread nearly entirely indoors in under-ventilated spaces. A key control strategy has been to bring in as much outdoor air as possible. What was once hand-wavy (“bring in more air!”) is now being codified…” hbr.org/2023/01/design…

👍 #aerosol twitter colleagues I am hiring a postdoc for my group starting ASAP - projects include dental aerosols, indoor air quality, environmental justice community based research. @Smogdr @HuffmanLabDU @jljcolorado @CathNoakes @built_envi @etgall @linseymarr @brandonboor

Excited to announce that my proposal was selected for funding by @USDA @USDA_NRCS! Over the next three years, I'll be leading this work in collaboration w/ @Mizzou to study microplastic export by stormwater runoff to urban farms under different weather patterns.

NEW TOOL from Harvard #HealthyBuildings team.
Not sure what size portable air cleaner to get for your room or classroom? (Or, have a portable air cleaner but not sure what room size it works best in?)

@j_g_allen Was on a flight w/o internet so I asked the flight attendant to check if the pilot knows the result! The pilot said he does not want to know it until he gets back home, but suggested waiting until the copilot gets the control and ask him. I heard the results from copilot! LOL

Too many organizations have said 'increase ventilation and filtration' but then shied away from answering the next question - "How much?"
To advance this, our Lancet @Commissioncovid Task Force proposed the following NADRs.

The Science Applications Team of the ASHRAE Epidemic Task Force developed ventilation guidance last winter but ASHRAE never released it.
That guidance finally saw the light of day in our Lancet report on ventilation targets.
Many, many thanks to those scientists for sharing.

Lancet @CovidCommission Task Force on Safe Work, Safe School, and Safe Travel has proposed three approaches to achieve "Good", "Better", and "Best" NADRs:
My personal favorite is the "volumetric flow rate per floor area" approach. :)

A group of experts developed new ventilation targets in terms of non-infectious air delivery rate with outdoor air, filtration, or disinfection:
Good = 4 ACH or 10 L/s/person
Better = 6 ACH or 14 L/s/person
Best = >6 ACH or >14 L/s/person
(area-based targets also available)

Big news — new clean air targets 🌪️ for indoors proposed by experts incl. @j_g_allen @CorsIAQ @linseymarr @drdavidmichaels @ShellyMBoulder @apsmunro, bc current ones too low for safety from viruses/bacteria 🦠 🧫 in air:
Good: 4 per hour
Better: 6 per hour
Best: > 6 per hour
