Question 1

At low speeds i hear a ticking or clicking sound, not quite a rattle, coming from the motor. Might be motor noise. Is this common? It's pretty loud.

Accepted Answer

I hear the noise too. I received mine today, and the noise doesn't really bother me. I'll see how it goes. If I can't tolerate it, I'll return the product. It sits in my living room, next to my couch. So usually the TV will drown out any clicking/ticking/rattling. Plus the fans/air kinda mask the noise. I don't really expect it to be a problem. It's likely the motor. I bet all units sounds the same.

Question 2

Fan/motor noise mentioned in numerous ratings.  This suggests cheap bearing(s) - probably sleeve type, not ball bearing. Anyone have fan/motor seize?

Accepted Answer

I heard Levoit will be releasing quieter 600S models in the future to address the motor noise. The older 600S models are already being phased out. I talked with Levoit customer support myself.

Question 3

For a 1400 sqft two story house, is one of these enough, or is it better to have a smaller one per room, or one per floor?

Accepted Answer

I have a condo, about 800 SQFT. I have a 600S in the living room that cleans the whole condo, if I leave all the interior doors open. I put a smaller 200S in my bedroom, so I can still have purified air while the door is shut. So, incase you want to live with all interior doors open, you'll need to buy smaller units for rooms where you regularly close the door for extended periods of time.

Question 4

For the everest air model, which of the sensors pm1,pm 2.5,pm10 will tell you that  you may have mold in the air?

Accepted Answer

The PM value (1.0, 2.5, or 10) refers to particulate matter (PM) less than or equal to 1, 2.5, or 10 microns in size. Please note that mold can vary in size and the sensor cannot distinguish different types of particles.
