Question 1

Does the 411i max have replaceable pre-filters? I says it does on the description but I haven't seen any extras listed on their website.

Accepted Answer

My memory is that I went to Amazon ad searched for filters and got a listing of the filters offered by THE manufacturer and some from others--I opted for a pkg of two filters from an outfit called Yweller and my result was that I was satisfied and saved some money. I do not remember if I had to search around to find Yweller but there were other off brand suppliers.
I cannot remember whether I reviewed these, I think I did.
Here is the info from a search of my past purchases: "weller Blue Pure 411 Replacement Filter Compatible with Blueair Blue Pure 411, 411+ and Mini,2 Pack Premium Foldable HEPA Activated Carbon Filter Part Number "
Hope this helps

Question 2

Does anyone who owns this, smoke cigarette's? and if so, does it get rid of cigarette smoke smell. ( if you do not smoke please don't answer)

Accepted Answer

I do not smoke, but I bought this air purifier because our basement flooded and we had a lot of construction work done, and there was a lot of polluted air during that time and it absolutely shows you when the air is polluted and when it clears up. I would absolutely believe that it would take cigarette smoke out of the air. My son-in-law has the exact same unit and he has it in his kitchen and whenever they cook bacon or fish it pulls at it that Out of the air and cleans it up

Question 3

Does this model hace an auto mode, which sense is the air quality, and when it needs to have a higher speed?

Accepted Answer

yes, it has auto mode, but compared to other air filters I've used in the same space in my house, it doesn't nearly kick-up higher, which concerns me.  My other air purifiers would get very dirty filters, but this one hardly turns on, saying the air-quality is great.  So I just turn on the fan in manual mode.
