Recommended Smart Air Cleaner for Home-Office (UV-C, HEPA, Ionisator)

Dear Entrepreneurs,

I know the HN Crowd cohorts one of the smartest and most tech-savvy communities. And I want you and me to breathe only the best air. Since, probably most of us are in the home-office, we need to take care of our well-being here too. In the office you have nice air-conditioning, but at home? Most of us, especially in Europe (Germany specifically for me) don't have AC and I think it's first of all too expensive and also very wasteful with electricity.

That's why I'd love to ask you wonderful people what you're using and recommending, when it comes to Air-Filtration/Cleaning systems.

Let's be honest Air conditioning (AC) devices are horribly inefficient. They are chunky, loud and use decades old technology. A "simple" compressor to just "cool" air + optional HEPA filter is not suitable for most of us for multiple reasons. Also it uses so much energy that it's environmentally not acceptable for me to use up 1-6kW/h for just cooling the room temperature.

That's why I'm looking to buy an improvement over a regular Fan. Something that is smart and can be controlled with the smartphone too. But there are so many devices and in such wild price categories that I hope to find an answer with your help for all of us.

Summer is coming and most of us are expecting new heat-waves too, including lots of pollen, dirty air, dust and funghi/viruses/bacteria. I have no connnection with them, but something like https://www.leitz.com/de-de/design--serien/trusens-luftreiniger/ but with smart-home capabilities in an acceptable price-range that most of us can afford would be great!

What are your suggestions for a device that cleans the air in the home-office (15-80 sqm)? Some of us have very little, others generous rooms, but the recommendation should work well with room-sizes up to 80sqm and even better with smaller room sizes.

I think an UV-C lamp killing germs, a HEPA filter for dust and dirt, an ozone-free ionisator to clean the air should be essential. Sorry if this is too naive, I'm a novice in this field, that's why I'm asking for your help.

Best and Thank you so much for your help!!
