Well, I stopped by my local vacuum store yesterday to return a small item at Ann Arbor Vacuum. I spoke to the owner, Adel, who has got to be the most knowledgable guy I ever met when it comes to vacuums and air filtration systems. He sells only products he considers top of the line, and he’s scientific about it.
While we were talking about HEPA filters on Vacuums (which is another topic, but Miele was impressive), somehow we transitioned to air filtration. I was writing my previous blog entry on air filters, specifically a home made filter system for under $25 . I didn’t know he sold air filters, but i one corner he had just one unit. He had considered others. He had travelled the floors at the trade shows. But he most most impressed with the engineering and effectiveness of the IQair health plus air filtration and purification system.
What I liked about Adel is that he was scientific. He had bought a professional air particle counter, and he walked around the room showing me the ambient particle counts in the room, and, most interestingly the HIGHER particle count at the exhaust vent of most vacuums, including those with HEPA Filters. The Miele vacuums were the exception , he said, and sure enough, they barely had any particles coming out–close to 0.
Anyway, he tested the output of the IQair health plus system, and whereas the room had a count of 800,000, the output airstream for this unit had ZERO particles larger than 0.3 microns. He took it apart and showed me the design, and this unit was impressively constructed, with a pre-filter, a charcoal filter (for odors and chemicals that can irritate the respiratory system), and a hyper-HEPA filter after that to catch the smallest of particles. It had several speeds, had a timer, a meter that demonstrated the life expectancy of the various filters. It was simply an awesome unit. One unit on high speed could clean 900 square foot of space (assuming 8 foot ceilings).

The photos shows the pre-HEPA filter (1), the charcoald/chemical filter (2), and the Hyper HEPA fliter (3) . Inside, there are simply NO gaps for air to leak around.
Now this sort of unit is not for everyone . First , it costs about $900. So what would it take for me to buy this? If I had severe allergies, severe asthma, severe chemical sensitivities I’d really consider buying this if I could afford it. I would not buy any unit now, except this one, without seeing the particle counter, or getting some reliable consumer review. This is a lot of money to spend, so if you are going to spend this much, be sure you research your purchase. Based on what I saw, I’d feel comfortable that this does exactly what it professes to do.
I hope this was helpful. Please write to give me feedback.
