How We Test Air Purifiers?and how to select air purifier?
In Olansi health care Co.,Ltd, all our air-quality testing is conducted in a 12×18-foot sealed room isolated from the rest of our labs. To test how well air purifiers clean the air, we place the air purifier in the center of the room and inject cigarette smoke and dust into the room by using a Venturi tube. We then use a machine that analyzes the particles in the air and measure the change in the air particle concentration over a 15-minute period at both the air purifier’s high and low speeds.
To measure noise, we use a decibel meter at ear level 4 feet in front of the air purifier and record the noise level at high and low speeds for each model. Annual cost is a combination of filter replacement costs and the energy required to run the purifier 24 hours a day for an entire year.
Before you resort to buying an air purifier, try some simple steps to reduce indoor air irritants, including:
Vacuum often and thoroughly using a vacuum with high-efficiency particulate air (HEPA) filtration.
Ban smoking indoors.
Maintain your heating and cooling equipment, and change air filters regularly.
Minimize the use of candles and wood fires.
Use exhaust fans in kitchen, bath, and laundry areas.
Don’t store chemicals, solvents, glues, or pesticides near your living quarters.
If pollen or related allergies keep you from opening windows, run your air conditioner or forced-air cooling system with a clean air filter.

PM2.5 Air Quality Index

PM2.5 Air Quality Index Here provides comparisons of air quality based on factors that have been shown to increase risk from air pollution. These factors can include life stages (children and older adults), specific health conditions (heart or lung disease), and increased likelihood of exposure from being active outdoors. The Air Quality Index (AQI) is the official index for air quality across the United States. The AQI ranges from 0 to 500. The higher the AQI value, the greater the level of air pollution and the greater the health concern. When AQI values are between 101 and 150, or code orange, members of sensitive groups may experience health effects. This is because they are more likely to be affected at lower air quality levels than everyone else. For example, children and older adults, people with lung disease, and people who are active outdoors (outdoor workers) are at greater risk from exposure to ozone. Older adults and children, and people with heart or lung disease ar...
