How to buy the good air purifier
1, choose to buy channels
When purchasing an air purifier, it is recommended to try to purchase it in formal channels such as shopping malls, electrical stores, brand stores, and mainstream e-commerce websites.
As of 2013, the brand, function, performance, design, and price of air purifiers are all very different, making people dazzled. It is suggested that consumers purchase products according to their actual needs, and not that the more functions, the better. For example, for those who need to protect PM2.5, it is recommended to choose an air purifier with outstanding PM2.5 purification capability. Newly renovated homes can focus on air purifiers with outstanding formaldehyde and toluene removal capabilities.

2, filtration technology
The particulate pollutant filtering technology is mainly HEPA filter. The quality of HEPA filter is uneven. Although some small brands of filters have high filtration efficiency, they have large resistance, low energy efficiency ratio, and they are easy to clog and have a short lifetime. It is generally recommended to use a deep-capacity-dust HEPA filter with an electrostatic electret. Static electret technology enables non-woven fabrics to be charged with positive and negative electricity to effectively trap particles in the air. Many HEPA filters are said to have electrostatic electret technology. However, due to technical reasons, the electret charge of many filters will attenuate quickly in a short period of time, resulting in reduced filtration efficiency. You can choose a commercially available HEPA filter such as 3M static electret, and use the same electrostatic electret technology as the 3M mask to permanently ensure that the electret efficiency does not attenuate.
3, focus on the area or particulate matter clean air (CADR)
The strength of the air purifier’s purification ability is mainly determined by the applicable area and the amount of clean air of the particulate matter (CADR: the rate of supply of clean air). The relationship between the two is: the applicable area = CADR × 0.1. The ability to purify other pollutants should be combined with the applicable area.
4, energy efficiency and energy efficiency rating
Air purifiers are usually used continuously for a long time. The energy efficiency ratio is an important indicator to measure the purification capacity and power consumption of air purifiers and deserves everyone’s attention. The higher the energy efficiency ratio and energy efficiency rating, the more energy-efficient the air purifier and the lower the cost of use.
5, ozone release
Ozone as a strong oxidant has a certain ability to purify, but it is harmful to the human body. The state has mandatory safety requirements for ozone release from air purifiers and is limited to ≤5 x 10-6% (ozone has a fishy smell).

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

图片
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...
