performs very strong, limited programmability generally a very good product. The fans are strong, the ozone generation is very strong, I can't measure how strong the ionizer and bacteria/germs killer is. Leave the ionizer on for too long, and the whole room smells like an aquatic swimming pool. I'd give it 5 stars if it offered more programmability. You can only turn it on and off automatically, you cannot leave it running and then "add" the ionizer at a certain time and "remove" the ionizer at a later time. You can only power it on completely and turn it off completely at a set time. And when you unplug it and move it to another room, it loses the time all over again, it would be better if it also had an internal clock that stores the time when unplugged. Also, the display is not readable, when the unit is on the floor. The remote doesn't show the data of the display, so you always have to bend to read what's in the display. A few things that make it hard or inconvenient to operate, but its cleaning performance is extremely strong.

This "air purifier" is a piece of trash First off, even at the highest (very loud) fan setting, there is minimal air being pulled through the system. I dropped dust directly behind (i.e. less than an inch away from) the filter and none of it even moved towards the system. It all just fell straight down. A month after using this at least 12 hours a day on full blast, I found NOTHING in the pre-filter or HEPA filter. It also doesn't eliminate smells AT ALL unless you put on the O-zone - which the manual admits is bad for you and shouldn't be put on with people in the room. Still, to further test, I lit a candle for 30 minutes in a small room, blew it out, then turned on the purifier to the highest setting, the fan to the highest setting, the ionizer, and the PC filter. I came back an hour later, and it still smelled strongly of the candle smell (only masked a bit by the O-zone).This thing doesn't purify anything. It's a big heavy box with a noisy fan in it. Supposedly the ceramic plate with the metal mesh is supposed to create ozone, that would be an odor similar to the smell after a rain shower, I bought 2 and neither one has that effect, I guess it filters the air ok but is noisy at the higher fan speeds, so much so you have to increase the volume on your tv to be able to hear what you are watching

I was a bit worried about ordering this unit. I had been doing a lot of research and realized quickly that you can spend a little or a LOT!! This unit was a value and after two days ~ it does exactly what it states....smells like air after a rainstorm! Only thing that I wish was different is the ozone setting... I don't have a problem being out of the house for a few hours to run that system, but my pet....well, where is he going to go? I am happy that it states remove pets tho....because their lungs are equally important! Easy to operate, assemble and maintain. This unit works extremely well. The price was great!!!! I'm very pleased with this. My son has had one and his mom in love. It's very pleasant walking into their home. I no longer have the doggy smell when we walk in the door. I would highly suggest this unit. How Intelli-Pro Purifies theThe air first enters the pre-filter, capturing the largest particles, which enhances the durability and performance of the other filters.

Washable Dust Collector Plates. The electrostatically-charged dust collector grid traps particles and pollutants like a magnet. This is similar to Friedrich C-90A, which is Consumer Reports' top-rated air purifier. Unlike the C-90A, the Intelli-Pro has multiple other leading technologies.air purifiers don't work The best type of air filter for trapping chemicals, gases,air purifier made usa odors and cigarette smoke. air purifier gas maskAccording to Penn State Dept. of Aerobiological researchers, carbon filters serve to remove odors, volatile organic compounds (VOCs) and chemicals that other filters cannot. The most effective type of air filter at capturing dust, allergens and other solid particles (including bacteria).

HEPA filters are recommended by the U.S. Department Carbon and HEPA filter are combined into one compact filter The most effective way to destroy micro-organisms, such as germs, viruses, fungi (such as mold) and bacteria. including those that are trapped by the HEPA air filter, preventing them from reproducing and recirculating through the room. recommended by the U.S. Centers of Disease Control. Safe and Effective Ionizer. Circulates trillions of negative ions to neutralize floating pollutantsA Journal of Hygiene study found negative ions to improve efficiency of filter units, and multiple studies (including those by the U.S. Dept. of Agriculture) have found ionizers to be highly effective against dust, bacteria, etc. the Intelli-Pro's ionizer is proven to be safe, producing virtually Clean Air Monitor - Know just how clean or polluted the air really senses just how clean or polluted the air really is, and conveys this

information through the four LED indicator lights. The dirtier the air, the more indicator lights that are lit. For example, if all four indicator lights are lit, the air is very polluted. If only one is lit, the air Saves you money on your electric bill by automatically the Intelli-Pro will automatically adjust the settings of the air purifier according to how clean or polluted the air is. For example, if the air is detected to be polluted, it will run the fan on a higher setting. On the other hand, if the air is determined to be sufficiently clean, it will run the fan on the lowest setting ("Quiet") in order to use less electricity, saving you money on your electric bill. Takes the guesswork out of knowing when Ion/UV Light Indicator - can know the ionizer and UV lamp are working properly. This sensor verifies the ionizer and UV lamp are working properly. it is very difficult to know if UV lamps and ionizers are fully
