HEPA filters are designed to remove 99.97 percent of all particles of 0.3 microns in diameter from the air without producing ozone. These filters are not effective against odors, VOCs or other gaseous pollutants, but they do not produce ozone. Ozone production is a legitimate concern in the case of air ionizers, especially for those with pre-existing respiratory problems. Fortunately, there are high-quality air purifiers that do not contain ozone. An air purifier with a high-quality HEPA filter system can effectively remove particulates from the air without producing ozone.
A built-in fan sends room air through the mechanical HEPA filter, trapping dirt, dust, and other particles. These filters also keep those particles in place, so you don't have to worry about dust or particles ending up all over your furniture and floor. Most ionizers have a fan to suck in air, so the particles settle on a collection plate instead of on chairs and tables. Let's take a closer look at ozone, how it might affect the body, and whether it's safe to use an air ionizer. Instead of running air through a filter to trap contaminants, ionizers emit negatively charged ions that attach to positively charged particles suspended in the air.
The CADR, or Clean Air Supply Index, measures how quickly an air purifier can circulate air from a given space through its filters every hour. For example, a unit with an air quality sensor automatically adjusts the fan speed after detecting a change in the air quality of a room. This function allows the air purifier to control and clean the air accordingly, ensuring that it is never left unprotected against bad environmental conditions. In addition, studies have indicated that ozone from indoor air ionizers may be even more dangerous than the same level of ozone outdoors due to direct exposure. With built-in air quality sensors and an app that provides real-time information about your home's air, you can track pollutants and act quickly to remove any harmful particles.
Therefore, it is extremely important to consider whether the ozone produced by a typical household air ionizer is acceptable for long-term exposure. Many of the ionizers used by companies such as Blueair, Coway, and others use mild ionization functions to improve the air cleaning performance of the HEPA filter. As for the air quality indicator, it works with the automatic mode which allows the fan speed to increase or decrease depending on the current air quality and as a result works automatically. A recent review of several studies revealed that HEPA portable air purifiers could significantly remove airborne SARS-CoV2 particles from the air. When it comes to protecting your family from airborne pollutants and allergens, it is important to choose an air purifier that does not produce ozone. Ozone can be harmful to your health if you are exposed to it for long periods of time.
Fortunately, there are many high-quality HEPA filter systems available that do not produce ozone and can effectively remove particulates from your home's air without any risk of exposure. When shopping for an air purifier, make sure you look for one with a high-quality HEPA filter system and an automatic mode that adjusts fan speed based on changes in your home's air quality. Additionally, look for an app that provides real-time information about your home's air quality so you can track pollutants and act quickly to remove any harmful particles.
