★☆☆☆☆
low cost low quality standard is adopted by this product
The executive standard of the product showed online is "GB/T38880-2020"
The executive standard of the actual product I received is "GB/T32610-2016".
There is a big difference: for PM2.5 particle, the minimum filtration efficiency requirement in "GB/T38880-2020" is 90% while the minimum filtration efficiency requirement in "GB/T32610-2016" is only 65%
