I did the petri dish challenge. You can clearly see a difference in the before and after. I wasn't expecting the after to have absolutely no growth, but it really didn't! Even if there were some growth in the after, I still would of been happy with any reduction.

I love this air purifier because there's no filters involved and the replacement unit on the system lasts about 3 years if not longer. I have the G3000 large room air purifier and it's solid built, made in the United States of America.

I purchased an AHPCO - 5009 for a AO 5000 Pro. Great unit. as all your products, they are fantastic. shipping was faster than expected. Your prices going up was a bummer, especially with so many people out of work right now but that's how businesses run now.

We have the 5000 in a lounge setting where nine men are "members" of a small cigar club. It's amazing how well and thoroughly this unit helps to keep the area from becoming absolutely disgusting...with typically two to four guys enjoying a cigar at any given time? The area should smell horribly and be rank...yet it is not and stays that way! Remarkable product! Thank you!

I first purchased this system for our grooming shop and loved it so much we bought 2 for our condo!
