QuestionWhy does the 100% not change? Had this for two days & it hasn’t changed & I know our open loft log cabin is a dust bowl?
Asked 3 years ago by Mk.
- Answer I've had my Shark 600 series for 3 days, and it never went off of 100%. I questioned this bc I have 3 cats and live off a gravel road. So after reading all I could about the Shark purifiers I tried putting it in the kitchen when I was cooking beacon. It was only a few minutes be for it went red. So I know it's working. Have you tried that?

QuestionThis might be a stupid question but is it just one room it purifies? For example if it’s in my room and the doors closed would it work throughout the house too? Or just the room? Or would you suggest putting it in the living room?
Asked 3 years ago by Customer.
- Answer I have ours centrally located in our apartment. I think that if you are closing doors off it would impact how well it worked. I just keep the room doors open and it has done an outstanding job of keeping the air quality good.

QuestionDoes the HEPA filter help with weed smoke? No one asked so I figured I would get the ball rolling.
Asked 2 years ago by Zoey.
- Answer Yes, it will filter any small particles in the air. It will filter weed smoke by capturing the fine airborne particles in the filter. Some of these particles cause odor which can also be reduced. My daughter lit a candle the other day and I was surprised that our filter detected the extra particles in the air and filtered them. Particles that land and cling to surfaces will not be filtered so it won’t be enough to eliminate odors but will reduce them so it “helps” with weed smoke.

QuestionIs this effective at getting rid of mold spores in the air.
Asked 3 years ago by Mold.
- Answer I perused the questions to seek out this same thing. There are two questions on this subject and Shark hasn't responded to either, although they have responded to other questions within the same time frame. I was very interested in this unit, but this leads me to believe I can't depend on it for helping with the mold issue in my place, which is imperative. For that reason I will need to choose something else as a non answer has to be taken as a negative answer.

QuestionDoes this remove radon from the air

QuestionJust plugged in. It instantly said 100% clean air which I find suspect. We have two dogs and a cat and a doggy door used constantly to a backyard with more dirt than grass. Not to mention a layer of dust on everything. Am I missing something?
Asked 2 years ago by JP.
- Answer I just plugged in mine after buying it today and it showed the same. I’m going to give it a bit to “acclimate” and see what happens.
