how loud are the different settings? Please compare to other common items.

Hello, we are showing around 50-70 decibels for low to high for Austin Air. Low is similar to a white noise, refrigerator, or moderate rainfall. High is similar to a driving in traffic or a dishwasher. 50 dB(A)@48 cfm on low, 55 dB(A)@180 cfm, and around 66 dB(a)@400 cfm on high. Since high is frequently too loud for many clients with any traditional air purifier, we often recommend running a unit on high only during the time of a new contaminant or for a few hours when you first use a unit. Otherwise, we recommend low or medium and run a unit 24x7 for best results. -- Thank you, Barb Lulay at USAirPurifiers.com, an authorized Austin Air dealer.

Does this purifier filter mold and mycotoxins?

Thank you for your question. Yes! Actually the Standard Healthmate with a straight carbon filter is all you need to eliminate the mold and. The Healthmate Plus has impregnated carbon mixed with straight carbon so it will eliminate the mold and more and that’s why its recommend for wildfire smoke. If you have further questions, please visit AmericanAirPurifiers and we always offer Free Delivery. Thank you,

How long does the filter last?

Depends on how dirty your air is - if you are smoking, or very have very dusty air, cooking odors - it won't last as long. Otherwise, 3-5 years - You do have to take out the foam filter surrounding the inside now and then and shake it out or rinse it. They said you can tell when the big filter needs changing by the air coming out of the machine not smelling good or if you notice odors staying in the air longer than before. I got it mainly to help with my allergies and breathing problems also for any bacteria and viruses. It does filter out 300 different particulates. I use mine 24/7 and it is still doing great almost 2 years later.

Can the wheels be easily detached (so I can place it in a precarious position on a flat base)?

The unit does not have wheels, it has small feet. They cannot be detached but they are rubber-like so they should "stick" to the surface. Hope this helps!
