Very Useful

I like QP Pro Air Qualify Monitor, the main display is bright and clear so I can see it from the distance. During this cold weather I choose to display humidity level as the main one so I can tell when I should turn on my humidifier. When I have guests I choose to display CO2 level as the main one so I know when I should switch my air purifier to high speed.

I'm very pleased with this monitor. Works well and when comparing it to my purple air appears accurate. I plan to download and analyze the data, which is a plus. The battery life is fairly short but it isn't a major inconvenience. I was going to buy a different monitor earlier this year but I'm happy I waited for this one!

I like it so far

I haven’t had it very long, and I feel as if I’m only starting to familiarize myself with it, but I feel that it was a good purchase. Set-up was effortless, and it seems to be working properly, providing all the data that it was advertised to give. I need to learn more about interpreting some of the numbers. It certainly seems responsive to changing conditions – – when I turn on my gas stove I can see PM 2.5, CO2 and tVOC jump!

Why Measuring PM2.5, tVOC, and CO2 Is So Important

PPM2.5: One of the biggest killers in the world, with 99% of population breathing dangerous levels. Even moderate levels are shown to cause cancer and heart disease. 

tVOC: Dangerous gases can irritate our organs and cause cancer

CO2: High CO2 levels can result in drowsiness, headaches, high blood pressure, and more.

*If levels are high, a combination of HEPA air purifiers and improved ventilation can help lower levels.air large text with an image to give focus to your chosen product, collection or blog post. Add details on availability, style or even provide a review.
