I’ve been asked about this inexpensive CO2 monitor many times, so I finally decided to pick one up to see if it’s better than the Vitalight (another affordable option). I paid a total of $34 for this, so I’m hoping it’s at least accurate because it could be a compelling budget option!

I’ve been super busy with work, so I haven’t had as much time to write recently, but I am currently working on a full review for the ultra-compact Airspothealth CO2 monitor.

This monitor is so convenient to carry around, and I love it for that reason.

Livegrid is a super cool Tamagotchi-inspired CO2 monitor that allows you to grow fish in a digital aquarium by maintaining good air quality. I'm very excited to review it in the coming weeks!

The AirValent TravelLite is a new CO2 monitor that shares the internals of the AirValent CO2 monitor but has a plastic housing and comes in at a lower price point. Full review coming soon!

Another exciting review is on the horizon! This time for the AirFanta 3Pro.

I'm very excited to give this a try as I’ve heard many good things about it.

If you’ve used one before, I’d love to hear your thoughts!

I've been testing a carbon monoxide monitor over the past month, and it's interesting to see how, even in outdoor air, the concentration can begin to climb. The highest concentration I saw outside was 31 ppm, near a very busy road.
