It is no secret that air purifiers can be costly, and they are expensive because the air they purify is very different from the air we breathe every day.

But it is often hard to know exactly what is going on inside the air purification equipment you’re using.

A study conducted by a team of scientists at the University of Washington showed that, depending on the air purity of the purifier you are using, there is an increased risk of disease transmission.

The researchers also found that people who use a very low-quality air purifying system have higher rates of air pollution-related deaths.

The study found that air pollution and health impacts were more prevalent among people who were living in areas with high air quality and in areas where air purging equipment was used frequently.

In contrast, people living in poor areas were more likely to report that they lived in areas without air purgers.

The findings of this study are a wake-up call for anyone using air purifications to be aware of their own risk factors for health problems, especially as air purifies rapidly from the start of a workday, so you should be careful with what you put into your air purify, said Dr. Michael Pfeiffer, lead author of the study.

You can also search the U.S. Department of Health and Human Services’ website for more information about air quality.

In addition, the U-M Center for Health Policy Research has a helpful website that shows you how air quality data is collected, collected and reported in the U, and what we can do to help make it better.
