Cannot be recommended for testing, measuring and checking.

Maybe it was just my device, but it was defective. The counter in my bedroom jumped from 35 to over 500 in just a few moments. The airflow hasn't changed either.

Pros
  • Built-in 2600mAh rechargeable lithium battery, after 1 full charge, it can work continuously for 32 hours and 30 days if used 1 hour a day.
Cons
  • Very expensive

Random Number Generator

There is no rhythm or reason behind the results this thing produces. I tested it several times in a closed room with no ventilation or fans and the only thing that was consistent about it was that it always said something different. There was some variation, although the air quality literally couldn't change. I returned it.

Pros
  • Large screen clearly shows the PM2.5 value. Five Level PM2.5 Concentration Indicator with LED Display Meets Excellent/Good/Mild/Moderate/Severe Air Quality
Cons
  • No Auto

Great for home use.

This helped a lot on the trail of the Dixie Fire smoke plume here in California. I have found that no matter what filter I used, my house actually leaks too much for a household filter fan to help! More bad air is sucked in than filtered out, which is why room air filters were needed. It has also helped identify various leaks in my house. The fireplace, air conditioner vents, dryer vent, and bathroom let in enough bad air that my filters couldn't hold. The battery also proved to be a lot more…

Pros
  • K01 is rated for PM2.5 as it is considered one of the most dangerous pollutants for human health due to its large size that can be inhaled and ingested by humans.
Cons
  • Long Shipment
