Dozens Pick Up Free Air Purifiers Amid Martinez Refinery Fire Concerns

Unless your house is hermetically sealed,,good luck and a waste of resources,,,placebo!

Will the refinery pay for the filters’ operation… Perhaps the Company should just go door to door and make sure All have them… and take responsibility..

Most likely the air purifiers plus the advertising plus staffing for this program were paid for by our tax dollars. The idea likely got an assist from PG&E to encourage more electricity use.

Most homes are not 100% sealed meaning air drifts in and out. This is by design to discourage the growth of mold and dry rot. You can test this by starting bathroom and kitchen fans that exhaust to the outside. Use your hand or a piece of paper to get a sense of how much suction and airflow you are getting at each vent. If your home is 100% sealed then the airflow will soon stop as you reach the limits of how much pressure the fans can generate. With 99% of the homes you will discover they air keeps flowing out through the exhaust vents. If you are in the 1% of homes where the airflow stops then try to open door that leads outside. If the door opens to the inside then it will pop open on you. If it leads outside you may not be able to open the door without a fair amount of pushing as the relative vacuum would hold the doors closed. If you end up stuck inside then turn the fans off and the pressure will quickly equalize as air comes back in through the vents.

This seems like the typical knee-jerk reaction since most of the smoke was blown east of the refinery and not directly into the local neighborhoods. People will always show up for freebees.
