Today I am reviewing the LFF Store Indoor Air Quality Monitor, LFF PM2.5 Detector, Temperature Tester, and Humidity Monitor Meter.
So, one of the reasons why I got this is because my area of California is known for terrible air pollution. When the weather is extremely hot, the emissions from the pollutants by the oil industry and agriculture (especially through burning of brush and cuttings) get trapped in warm air and while things are slowly getting better, but even then, we are having wildfires often that even causes a threat to our air.
So, sometimes it’s good to know how bad things are with a air quality monitor, for outdoor and indoor.
I have an outdoor meter, but I wanted an indoor. So, I gave this LFF Store Indoor Air Quality Monitor, LFF PM2.5 Detector, Temperature Tester, and Humidity Monitor Meter a try.
I was interested in the fact that you get the time, the temperature, the humidity and air quality in colorful VA-LCD color screen.
The device is fairly easy to set. You get three buttons, one on the left to dim the LCD’s, the one on the right to brighten the LCD’s and the center button to turn on/off the unit but a long press to set the time and also if you want 12/24 hr, Fahrenheit or Celsius.
While it does come with a USB connector, which I plug into a power strip with USB ports, it does NOT come with a rechargeable battery. In this day and age where these type of digital meters do have it, I am going to strike with a half a star off just for that. Because each time you want to adjust and even unplug it, you have to reset the time because there is no battery. I didn’t like that at all.
Many meters these days have the temperature and humidity and like many other metering units, they are +/- 5 (no device ever produces the same results, in my experience) and tested it with my CO2 meters and the temperature and humidity for this unit was within range. The temperature was just off by 1 compared to my other CO2 meters but humidity was off by 4-5. But that’s not bad.
So, how to read the PM in air quality.
On a clear day, the average is PM2.5 as shown on the screen and the concentration can be low as 5 ug/m3 or below. If you see the numbers go above 35.4 ug/m3. It’s considered unhealthy. The PM2.5 index is tested every five seconds while the other two is checked every 30 seconds.
So, using this, knowing green is good, yellow is moderate and orange is unhealthy.
My indoor is always at 2 or 3 ug/m3 early in the morning but can get up to 4 or 5 as the day progresses and then back down.
But I do like this meter a lot and I believe if LFF Store can find a way to incorporate a rechargeable battery, it would be much better.
The LFF Store Indoor Air Quality Monitor, LFF PM2.5 Detector, Temperature Tester, and Humidity Monitor Meter is definitely worth having in the home but as mentioned, the lack of a rechargeable battery and having to change the time if the USB cable is accidentally removed or comes unplugged is a pain. But otherwise a very good device!
4.5 stars!
