According to WIKIPEDIA, the different air-cleaning techniques are Thermodynamic sterilization (TSS), Ultraviolet germicidal irradiation (UVGI), Filter, Activated carbon, Polarized-media electronic air cleaners, Photocatalytic oxidation (PCO), Ionizer purifiers, Ozone generators and Titanium dioxide (TiO2) technology.
The purifying air of the notion has merit, however. You know a house is a source of air contaminants. Generally, it makes the air inside the home is dirtier than the air outside. Mold and mold spore’s developer can be lead by moisture.
#3. What is purified air?
Purified Air means the air free from any kind of disease, dust, and filth and overall any kind of chemical particles. It is a matter of good feelings that a qualified HEPA vacuum cleaner can remove all kinds of heavier particles from the air.

Climatologists consciously warn us to avoid those harmful gaseous particles. Actually, all kinds of dust are not a problem at all. So an air purifier works only for harmful particles.
#5. Careful about Carbon filters and others
According to experts, an air purifier needs to replace Carbon filters every 3-6 months. The safer course: Always you should follow the precautions on the manual of the product. Suppose, don’t use it in non-ventilated spaces.
In the process, they produce ozone as a byproduct. You can also find dedicated ozone-generating devices. The devices produce relatively huge amounts of this gas.

Ozone in the higher atmosphere protects us in the sun’s ultraviolet rays. Ground-level ozone is irritant that will worsen asthma. It spoils your ability to fight asthmatic infections. We believe that home air cleaners that emit even a small amount of ozone are an inadequate choice.
If someone in your residence has pulmonary problems or even allergy symptoms. We also would like to suggest that you should avoid dedicated ozone generators totally.
