Join the DMsensors family and enjoy a life where air quality control
is not just effective, but also delightfully simple. With the DN690R, you’re not just buying a monitor -- you’re investing in a healthier, simpler way to live.
The device works great! I used to get more headaches but now every time it tells me the air quality isn't great, I open my window and it helps!
Had this for a few months on my desk and it's always a joy to see that very well designed enclosure holding up such a high contrast screen telling me how poorly insulated my windows are with its precise temperature sensor. The battery life is also a pleasant surprise.
With baby number 2 on the way, we decided to give DN690R a try. Now we sleep peacefully knowing our babies sleep breathing the best air in a perfect temperature room.
I love it so far. It helps me monitor my air quality and stay on top of my health.
