User Manual Winix 5500-2 Air Purifier

It will speed up when it is actively trying to clear air. Once it cleans the air, it will go back down to your low preset.

Depends on how you clean it and with what. I use dawn with a cap or 2 of pine sol, warm water and start switching and wringing it out. It might take a couple of times but a little time is less costly.

Depends on your settings. If you have it on Auto the sensor clicks on and off. Turn (Auto) to the off position set everything to high when cooking and dusting and see what happens.

Not unless you go inside if you know what your doing. But there’s a switch that you can turn on and off the plasma unit.

No. Carbon is activated and will lose its charge over time. Washable or not, you need to change them out. There are aftermarket brands selling the filter only but it is not recommended.
