Offline gadgets that I'm interested in? There are a few. Closest to my heart are those that promise cleaner air. I came to appreciate them since I live in the city center where we pray for the rain to wash the dust and noxae. I have tested in the past and Venta, that are rather good for humidification, or something from Philips which does the same thing. Both make and filtering but they do not come close to the status of a purifier. Let me explain.
We are now testing a PerfectAir ProClinic, an air purifier, pay attention, not an air filter. It looks like a radio from the 60`, I know, but like our grandparents radio, it is made to last and probably our grandchildren will inherit it. I will therefore insist on what it does not on what it looks like. And I brought into the studio for testing a special testing device to convince us if that the 99% filtration is true or it's just a cheap advertising.
Breifly, Perfect Air Pro Clinic purifies the air in the room, even four times in an hour. That is if you have an apartment smaller than 70 square meters. Yes, it based on filters also, but much better, and also a UV lamp that destroys any viruses or bacteria that could have escaped from the HEPA filters. Let's open it and see what it's capable of.
