I was sceptical at first, but now I'm completely convinced. The air quality has improved greatly. I am amazed how dust and rubbish is in the air in winter. When airing, the number of particles increases significantly. However, the automatic mode still ensures good air.

This is very quiet compare to when running at low setting but gets noisy on high. Make sure you buy the air filter based on 30% of advertised area so you can avoid running the fan high.
The sensor is also more accurate.

There is improvement in maintenance, for example the cover can be removed and the fan can be cleaned. All sensor can be cleaned as well.

However the light cannot be totally turn off at night compare to Pro. Having said that It is not very bright so it is not too bad.

My partner has a dust allergy and due to the shelving and items around the house dust would be visible around the room every 2 days. since i got this i have no seen dust for over a week, my room feels fresh and i dont remember the last time my room smell like food after eating in it.

I originally purchased a couple of these a couple of weeks ago to give our office and print room an extra degree of protection from Covid, but I've also found they have helped remove chemical fumes and gasses from our printing room, and have stopped a niggly dry cough from one of our staff which appears to have been a sensitivity to the chemicals. They arrived promptly, were easy to get going and don't take up much space. Wish I'd got some ages ago.
