AIR quality monitor

[yjj1]

Hello all,

I'm thinking to buy an indoor air quality monitor for my house.
Is there any product you want to recommend and share with me a reason?

Thank you

Why?

I want to buy one for my brother and his family.
Do you know any good product?

Do you mean an air purifier that’s good for allergies etc or an actual machine that just measures air quality, which I can’t fathom why you want?
