I was so excited when my air purifier arrived. I'm familiar with the Honeywell brand, so felt confident that I was getting a quality product. The air purifier was easy to set up and I already had a place in my bedroom picked out. The unit has several  purifier settings: germs, dust and pollen...just tap the on/off button to scroll through.  The unit also has a lighted display to make it easier to see which setting you've chosen.  I've only had it for about 3 weeks, but have already noticed a freshness in the air quality.  I highly recommend!
