Is the air purifier more effective with high air volume? How to control it when using it?


From a professional point of view, the air volume is only one of the many parameters of the air purifier, and the larger air volume doesn’t mean the more effective it is. The performance evaluation index of the air purifier is CADR (clean air volume) = air volume × one-pass purification efficiency of the purifier. Therefore, the effect of the purifier depends on both the amount of air output and the single pass removal efficiency of the contaminants.
When the concentration of indoor pollutants is high,hihg level wind speed should be turned on. In general, the amount of wind is reduced, and the CADR is also reduced, that is, the purification effect is deteriorated. If the noise is high, you can switch to medium and low air volume to reduce noise when the indoor pollutant concentration is reduced.
The noise is related to several factors. Firstly, the amount of air. The larger the air volume, the louder the noise there will be, because this is the sound of the wind. Secondly, the larger the air volume, the faster the motor speed, the higher noise of the motor is. The third factor is the air duct design . The design problem of the purifier, some products easilly produce noise because of the poor design of the air duct, the wind flow is not smooth.

Development Trend of Water Purification Market 2019 Posted on  May 10, 2019   by  olans228 According to the offline monitoring data of AVC, the development speed of high-throughput products greater than or equal to 200L is fast and increasing. The proportion of high-throughput products is nearly 64% in the first half of the year, while the share of low-throughput products is gradually decreasing. The water purification industry is developing towards the direction of large flux, long life, high water saving, and intelligentization. More consumers have opted for high-throughput reverse OSMOSIS WATER PURIFIERS Reverse osmosis technology  has gradually become the mainstream of the market, in ultrafiltration, activated carbon, nanofiltration, and other technologies ranked first. In the first half of 18 years, reverse OSMOSIS technology products accounted for 90% of the total. Large flow for Reverse osmosis with WIFI will be very hot for the market. Welcome...

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...
