Dylos DC1100 Pro Air Quality Monitor vs Levoit Core 400S

  • Great for testing air quality
  • Easy to use
  • Good value for money
  • Reliable and accurate readings
  • User interface is dated and underwhelming
  • Great for large rooms
  • Works well when the filters are clean but not so good when they are bad
  • It is pretty big, but not heavy enough to be difficult
  • Noise level is pretty quite for the amount of air it moves
  • HEPA units seem to be of nice quality, packaged well

Pollutant Reduction

Dylos DC1100 Pro Air Quality Monitor
Would using a smart outlet to turn off my purifiers when not in use to help extend the life of the filters?
But to do that you need an accurate meter. I've got three purifiers that I rarely need to use based on PM levels. I currently use a Dylos 1100 pro but will soon be testing P. urple Air units. I try to keep pm2.5 levels below 2micro grams/m3 , and find this easy to do with infrequent use of my purifiers.
Levoit Core 400S
I bought a Levoit Core 400S for Mother's Day and just set it up. My mom has been having bad allergies and sometimes has coughing fits, so I thought it could help with that. But apparently our PM2.5 is already very good (5 when I turned it on, then dropped to 1-2 after a while). We don't have any pets and clean the house once a month.

Levoit Core 400S
Outstanding device, smart app wants too much phone access
The noise level is pretty quite for the amount of air it moves. It is pretty big, but not heavy enough to be difficult to move. Does a great job filtering the air. I liked it so much I bought a second one a few days later for my mom when she complained about her allergies. When you unpack it, make s...

Levoit Core 400S
So far so good!
I have owned this product for less than 24 hours as of this writing. More updates as I have more to say/remember to do them. Also, I will be very verbose, the sort of in-depth information I want when I am researching products over $99 for purchase, so you really know what's going on. Hopefully it he...

Allergens

A very useful device for asthma sufferers
I purchased an IQAir Health Pro Plus a few months ago after suffering from a bad bout of bronchitis. I developed a variant of asthma which leads to coughing excessively when the air quality is poor. The IQAir has been a great addition to my home, but it bothered me that I had no scientifically objec...

Levoit Core 400S
Either defective or pointless
I smoked a cigarette and blew it at this and it didn't go up from "5". When I moved it inside, it just blew cigarette smelling air into my room. Right there I knew I was most likely returning this product. The entire time I had it it would just randomly go from 5 to 1... my allergies were the exact ...
