Q: Why is the blue light now yellow? Just changed the filter but still yellow.
A: HI there! Thanks for reaching out! The unit doesn't know that the filter has been changed. Press and hold the button down for a solid 15 seconds the light should blink then go back to normal.
A: Hi! The filter for the 411 does indeed come with a layer of activated carbon to handle smoke, odors and VOCs.
Q: Is this product a Hepa A Filter ?
A: No, the filters for the 411, 211+ and the 121 are not HEPA. HEPA is just an acronym for High Efficiency Particulate Absorption and refers to filtering particles from the air via a weave and it generally has a range of 90-98% efficiency as to what it’s taking out of the air. Whereas units in our Classic, Sense and Pro lines do use true HEPA filters 97-98% efficiency, the filters in the Pure Blue line of units are about half as dense and 97% efficient. We’ve done this in order to provide for a compact or beginner version of this line of air purifiers.
A: HI there! Thanks for reaching out! All of our units have small Ionizers in them which cannot be turned off.
A: Hello Kate, we are sorry for the experience you had. It does seem like the light of the 211+ is not functioning as it should. Please try to hold down the power button firmly for up to 45 seconds to a minute. If the problem persists, we suggest arranging for an exchange from the original BestBuy you've purchased from or contact [email protected] and request for a warranty exchange. We'd be very happy to send you a new one under warranty.
Q: Does this come with all filters included or do I have to purchase anything separatly???
A: yes everything you need to start using it is in the box will need replacement filters later
A: Generally, drywall dust will destroy air cleaner and vacuum motors. Especially in high moisture conditions. Think plaster cast on your motor. Consider renting a air scrubber from a tool rental center otherwise plan on throwing it out and going through a filter once a week. Also, consider hanging plastic between room door ways and closing off return air vents where you have construction. This is not ideal for long projects due to static pressure but, you don’t want that dust in your ducts.
A: The Blue comes with two washable fabric pre-filters in black & blue colors. There are 3 other colors for purchase. The main filter is the particle filter which needs replacement every 6 months depending on your use. There is no carbon filter with this unit.
