How to air purifier?

Air purifiers need room to breathe, so make sure they have a few feet of clearance around the top and all four sides for unobstructed air circulation. Point the flow in the right direction. The best way to improve indoor air quality is to eliminate sources of pollutants and ventilate with fresh, clean outdoor air. Room air purifiers can help when those methods are insufficient or not possible.

Multiple studies of room air purifiers show that the use of HEPA filters results in reductions of 50 percent or more in particulate matter. Now more than ever, Americans are looking for ways to improve indoor air quality, and air purifiers are leading the pack in strides to achieve cleaner air.

An air purifier can provide the fresh air you are looking for as long as you have sufficient airflow and the right type and quantity of filter media. Air purifiers filter allergens and air pollutants that the human eye can and cannot see. The California Air Resources Board (CARB) maintains a list of all certified air purifiers that meet ozone standards. As for coronavirus, air purifiers with HEPA filters are capable of capturing the droplets that the virus travels through (when people cough, talk or breathe).

To find an air purifier that works for allergies, you need to look at the effectiveness of the HEPA filter and the quality of the engine. Some air filters on this list include the Air Oasis 3000 Xtreme G3, Alpine Air Living Air Classic and Surround Air Multi-Tech II XJ-3000D. If the filter is a real HEPA (99.97% efficient) and has an airflow of 200 cfm, then the CADR will be at 200 or just below. They usually have a small screen filter that can remove very large dust particles, but not the smaller particles that air purifiers are designed to capture.

Negative ion generators or ionic air purifiers use tiny charged wires or needles to create negatively charged gas molecules or ions that adhere to airborne particles and accumulate in the filter. A negative ion generator can sometimes be the only cleaning element in the air cleaner, or it can work in conjunction with a HEPA filter. An air purifier can act as a supplement to a filter and other strategies to help remove the following particles.
