I have a household of family who have severe allergies.  I was quite excited to try the Instant Air Purifier.  It's WONDERFUL!!!  The sleek, attractive design makes it a great addition to our home while helping purify the air we are taking in.  During times of heavy pollen, my family was impressed by the Instant Air Purifier and thought it definitely helped.  I'm so glad we gave this air purifier a try!  I'll be purchasing another for another area of our house to ensure my family is covered.
