No, the filter is heated to 200C, not the air. They don’t say what the temperature delta of the air is after passing through.

- joe_the_user 6y agoGood point, though if air continually passing through, the temperature delta would be significant.
- praptak 6y agoThe article says the virus is deactivated at 70C, so the air itself should probably get to 70C plus perhaps a safety margin. Come to think of it, if you coupled that with a heat exchanger, the filtered air could pre-heat the incoming air and get cooled in the process. This way the filter would only have to transfer enough heat to make up for the inefficiency of the exchanger. I'm not sure if this is feasible.
- dTal 6y agoIt's probably perfectly feasible - it's the same working principle as a dehumidifier, except temporarily heating instead of temporarily cooling. Just reverse the polarity and you're set!
- adrianmonk 6y agoA filter might be easier to install in an existing forced air system. The main problem that needs to be solved is how to eliminate the virus between now and when a vaccine is available. So solutions need to be something that can be manufactured quickly and dropped in as a replacement for a component of an existing system.
- sizzle 6y agoWouldn't the filter simply be placed on the air intake side prior to passing through the HVAC coil and being cooled? Why heat the air after it is passed through the coil and is cooled?
