Electric Smart N95 Haze Mask Anti-Fog Anti-Baacterial PM2.5 Resusable 3 Filter
たいへん良い充電中これから使います
I'm sorry but the power button doesn't work. The fan did not start first. Then I re-connected the power and the fan started. I managed, with the power button to vary the speed. I was unable to turn off the fan. To stop I had to drain the battery. The filter is really poor. I look forward to your reply. Sincerely.
It was very useful in our actual situation, since helps a lot avoiding sofocation, but lasted few weeks before it stop working.
Ziet er prima uit. Ventilator doet het prima. Gaat alleen moeilijk aan en uit.
