I relish filling my lungs with Northwest air. I can taste how clean and different our air is from rest parts of the world every time I leave our region. The new summer smoke season makes me appreciate when I can really fill my lungs with the good stuff. Especially during COVID, air awareness has become a greater consideration in rooms and buildings; cross breezes are mapped to minimize sharing your breath with others and we anxiously take a deep breath of unmasked air as soon as we are in our safe zones.
And the summer smoke season really brought home (literally and figuratively) the importance clean air in our homes as the smoke particles found their way in through the tiny cracks and crevices in our walls and windows. What can you do to minimize your chances of breathing viral particles and standing smoke? There are many approaches, including:
- Attaching furnace filters to box fans.
- Window fans blowing outward to expel stale or polluted air.
- Avoid unconditioned spaces.
- Improve central air filtration.
- Ventilation and filtration provided by heating, ventilating, and air-conditioning systems can reduce the airborne concentration of SARS-CoV-2 and thus the risk of transmission through the air WITH the right filtration (that is a whole science on it’s own!)
- Wear a mask, yes even in your home or vehicle.
- And, of course, air purifiers.
While it is easy to see when you need to dust or sweep, it’s a lot harder to see when your air needs cleaning. Air purifiers work by creating finer and finer filters. Purification can be improved by conducting a static electrical charge. Purification efficiency is measured in MERVs, a higher MERV rating means increased filtration from 1-16. Airborne viruses can be caught by any filter MERV 13 or greater.
Many of our design partners consider air quality in their design work and have seen an uptick in demand lately. One of them, Entero Design, has gone as far as to supply some great systems – such as one in which the air is filtered through a proprietary Coconut Carbon/Purafil media for a 99.26% efficiency, capturing particles of .3 microns and larger. The whisper quiet operation is Multi-Function, removing both gases and particles from air. Mighty House had one at our office that now (as that space is abandoned) is much appreciated at our home.
The New York Times Wirecutter article analyzed what they considered the Best Air Purifiers on the market.
Another option for more whole house ventilation and air cleaning is the Lunos HRV System. The system is composed of paired through-wall paired fan units with regenerative heat recovery cores. This captures heat from escaping air and puts it back into incoming air. These take a lot more forethought and finessing to install than a plug-in air purifier though also have a number of additional benefits too. Reach out to us to learn more.
