How much would it cost to lower the PM 2.5 in his house? Even cut it in half?
I don't know your friend but for some people they can afford air purifiers, running the A/C, and keeping the windows closed, but they feel it's not worth it. It's seen as a wasted expense. Especially true during Covid when many doctors could have retro-fitted their practices with HVAC filters. I think we really need an educational campaign.
- aidenn0 4y ago"running the A/C," presupposes that the house has A/C. When a wildfire is near, I close up the house and run air-filters, but it can hit 100F inside in the afternoons.
- jahewson 4y agoActually it doesn’t have to be A/C. If you have central air then you have a HEPA filter so just run the system’s fan.
- aidenn0 4y agoYes, I have no problems with the particulates, it's the temperature that's the problem with the windows closed.
- schiffern 4y agoOne option is filtering the air immediately before you breathe it in. The active airflow can greatly mitigate common comfort issues with traditional masking. It also gives you some protection outside, which is nice. https://www.amazon.com/BROAD-Rechargeable-Electrical-Purifying-Respirator/dp/B07YWLBVF2/ https://www.amazon.com/BROAD-Rechargeable-Electrical-Purifyi...

In one room, plausibly reduce it by 99% for a one-off $70 air purifier and $30/year of electricity costs and replacement filters: https://dynomight.net/ikea-purifier/ https://dynomight.net/ikea-purifier/
