To this day we know that one of the best strategies to try to prevent COVID infections is the crossed ventilation. It is true that each time they are making it more complicated for us and that with the current incidence any precaution is little, but having the windows permanently open at home and / or at the office it is unpleasant, especially now that the thermometer has returned to winter temperatures.
The carbon dioxide meters They allow us to have a fairly approximate idea of how clean the air we breathe is indoors (also outdoors, but indoors is what interests us in this case). So we can control the closing and opening of windows based on the CO valuetwo that we observe on the monitor. Between 700 and 800 ppm, as a maximum, we should act with the appropriate measures to renew the air of the room in question. Keep in mind that if there is little wind outside, the level of carbon dioxide will be very difficult to lower naturally once it has risen, it is best to always keep it at low levels.
Today the carbon dioxide meter has become a highly demanded device and there are many more options on the market to buy it than a year ago, so we have taken a look at Amazon to show you some of them with different prices and designs. . Starting with this air quality detector that measures COtwo And it has a strap to make it portable and that costs 58.89 euros.

Netatmo also offers a quality control system in the environment that includes measurement of CO levelstwo and it costs 102 euros. The one that is associated with a mobile app may have pros and cons. Personally, for carbon dioxide I prefer that the values appear on the screen of the device itself so that all the people who share a room can see them whenever they want in real time, but control through the mobile can have other advantages.
