There are four fundamental, non-negotiable needs of the human body if we wish to live: These needs are air, water, sleep, and food. Air is the most critical. We are constantly exposed to microparticles in the air. A quality air filtration system can help remove these particles. High-end units can even remove volatile gases. The greatest impact we can make on air quality is to have a filtration unit in the bedroom. Several examples of air filtration units that I use can be found on the Amazon affiliate page, and there are many others.

An added benefit is the white noise these units create, which can help mask outside sounds and improve sleep. Make sure the unit has a night mode without lights to keep your room dark. You will understand the importance of changing the filter on a unit that has been running for a few months. I am always amazed by how much dust the filter has removed from the air.
