Review: En Monterrey donde radico estamos teniendo problemas con el aire y aunque llevo 3 años con el producto y funciona bien he investigado la marca y dan información confusa sobre el producto. Tiene un filtro HEPAsilent que no es un filtro HEPA real. La marca engaña con esa información porque hacen creer que si es HEPA real. Solo por eso estoy decepcionado de la marca!

## Questions & Answers

**Q: Went to check the manual for a question and just realized out Blue air did not come with a pre-filter. Wasn't it supposed to?**
A: Hi there, your Blue Pure 211+ Auto comes with one pre-filter in Arctic Trail, which may have come pre-installed on the unit (the grey external fabric).  If this is not the case, please e-mail info@blueair.com and we will be happy to send a replacement.

**Q: From which PM2.5 reading does the air purifier start increasing fan speed?**
A: I have not seen it automatically increase fan speed.  I set it on the 1,2 or 3 setting and forget it.   Maybe it can alter fan speed but if so it's not noticeable to me.

**Q: Where can additional Of the new style Pre-Filters be purchased?**
A: The Blueair website has the pre-filters if you can’t find them here.

**Q: I live in the country, lots of dirt + 3 dogs and 2 cats, how often will I need new filter?**
A: Hi there, our formal recommendation is to change the filter every 6 months of continuous use, but you may check your filter periodically and replace it on an "as needed" basis if you prefer.

### ⭐⭐⭐⭐⭐ Review
*by G***A on 26 August 2023*

This air purifier improved air quality discernably in our 2-bedroom condo during the recent choking wildfire smoke. Glad we bought it. Very quiet in night mode and acceptable during higher settings. The HEPA filters can be replaced easily however they are still okay after about 100 hours of use in the medium speed setting and with closed windows. The touch controls are neatly integrated and unobtrusive however we would prefer simpler ergonomic buttons or nobs located on the side because it is not easy to find the right setting without numerals or idiot dots. Please redesign the controls to earn 5 stars.
