House for more than a month, the indoor air is worrying. Tell me how you all purify the air.

I feel the same way. For more than a month, I open the window for a short time every day. My friend recommended me to use panasonic air conditioning, which is said to be a patented nano-water ion effect, which can sterilize and deodorize and deeply clean the air conditioner itself. I searched official website and found that AE/AW series, EN series and HEN series all have this effect. You can study it carefully.
