Dust Window Filter
Outdoor PM2.5 levels are high. Can we still open the windows?
It's generally not recommended to open the windows because PM2.5 can enter indoors.
However, if you have installed the :dc PM2.5 Window Screen filter, you can open the windows with peace of mind and breathe freely.
The :dc dust window filter acts like a mask for your screen, blocking PM2.5 from entering indoors while allowing fresh air to come in.
Most haze screens on the market use electrostatic and weaving methods for haze filtration. They require complete stillness and no wind to have minimal filtering effects; otherwise, PM2.5 particles will be blown indoors by the wind. Although they may advertise a feeling of airflow indoors after installation, in reality, haze particles are extremely small. If there's airflow indoors, haze will also be carried in with the wind.
:dc Dust Window Filter achieves a balance between filtration efficiency and breathability, allowing PM2.5 , smog particles to be blocked outside while still allowing fresh air to enter indoors.
It's DIY Installation,
