Also known as a Corsi-Rosenthal box, this DIY method of building your own air filter with MERV13 furnace filters and a box fan are an easy and cost-effective way to help clear indoor air from airborne virus particles, wildfire smoke, pollen, dust, and more!
If you can seal a box, you can build one (or 100!) of these!Read More »DIY box fan filters – Corsi-Rosenthal box
When someone in your household needs to quarantine at home, you want them to be isolated from others as much as possible. Remember that the virus transmits predominantly through the air, so sanitizing surfaces is not enough.Read More »Someone in my home has COVID. How do we isolate safely?
SARS-CoV-2, the virus that causes Covid-19, can float in the air like smoke. Aerosolized particles can linger in poorly ventilated indoor spaces, spreading farther than 6 feet from its source. We need to think about controlling the source of the virus indoors, about ventilation (mixing more outdoor air with indoor air), and about air filtration and cleaning devices.Read More »Ventilation
We know that HEPA and MERV13 filters work to remove airborne virus particles. Read all about it from the EPA, CDC, OSHA, and ASHRAE.Read More »Air filters work – EPA, CDC, OSHA, ASHRAE, and more agree.
Choose only air cleaners that have mechanical filtration ( particulate filter media) with MERV 13 or higher or HEPA designation. Watch out for ionizers that can produce hazardous ozone. How to choose? There is help!Read More »Portable Air Cleaner (HEPA filter) buying guide
What are Elastomeric Respirators?
They are tight fitting respirators made of synthetic or natural rubber material, can be
repeatedly used, disinfected, stored, and re-used.
• They are equipped with replaceable filter cartridges or flexible, disc or pancake-style filters,
which are not housed in a cartridge body.
• They may also have sealing surfaces and adjustable straps that accommodate a better fit.
