HEPA air filter running all day.?
This may be a crazy question, but my HEPA air filter is et to automatically come on as needed, it usually stays at low. Today it has been running high ALL day. othing is different in the house. Could this indicate something dangerous like gas or carbon monoxide? Thanks
Probably not.
You should have a carbon monoxide detector in your house anyways.
They are cheap enough and they work just like a smoke detector.
You can find them at any local home improvement store.
Or call the manufacturer on it.
