purifier
Britishnoun
Explanation
A purifier is something that filters dangerous contaminants out of water or air. If you bring a good water purifier along on your camping trip, you can safely drink from rivers and streams. Air purifiers are useful for removing dust and other allergens from the air, as well as smoke particles and even viruses and other microscopic germs. People with gas stoves or wood-burning fireplaces in their homes often use air purifiers to ensure that the air they breathe is safe and clean. Purifier comes from the verb purify, or "cleanse," and the Latin root purus, "pure."
