yes, you'll find out first hand if you buy a PM2.5 meter and measure locally in your environment. We have a battery powered one we'd take on trips with us and in the car. Buy a Bosch HEPA cabin filter for your car too, it makes a measurable difference.
- neogodless 3y agoSeems like a good meter? I can't find any reliable indicator of which might be worth the trouble.
- jxramos 3y agoyah it's hard to verify whether or not the thing has true absolute accuracy. However once I started experimenting in real world scenarios where I was able to corroborate my own subjective interpretation of my senses the numbers did correlate and scale proportionally as hoped. When it was noticeably smoky outside the numbers registered high, the higher the smoke smell the numbers reflected proportionally so. I would do experiments like vacuuming and seeing what showed up. Cooking with smoke being generated, the numbers would grow. Mine has some VOC mode too, when I took the thing to the gas station that number went way up which was pretty illuminating how much VOCs we breathe in at the pump. Another angle to the experimentation was with and without the HEPA filter being ran. When smoke would infiltrate the indoor numbers would be like 10 or 12. Run the HEPA for say 20 min the numbers get down to 2 or 3. To me that thing was doing what I expected and served us well in the wildfires.
- slaw 3y agoI bought smartmi PM 2.5 meter 6 months ago. It is very simple just power button, brightness and display. I watched YouTube video where it was positively reviewed. https://a.aliexpress.com/_EIjHR2h https://a.aliexpress.com/_EIjHR2h
