Monitors pollution levels, pollutant types and filter performance
No more guessing how clean or dirty your air really is
The Clean Air Monitor tells you whether the air in your home or office is clean, filthy, or somewhere in between. There are four indicator lights representing each category of air quality (from left to right): Clean, Some Pollution, Significant Pollution, Severe Pollution.
Know exactly what you are breathing in
The Clean Air Monitor doesn't just tell you 'how much', but it also lets you know 'what'. The lower indicator strip shows the type of pollutant being detected by the sensors, whether it be dust, allergens or odor-causing compounds.
The right amount of power for the right amount of pollutants
When set to Auto Mode, the Intelli-Pro XJ-3800 will automatically adjust settings according to the level of pollution being detected. For instance, if severe pollution levels are detected, it will ramp the unit up to the highest power setting, protecting you from contaminated air. If no pollution is detected, it will lower itself to Quiet mode, minimizing both sound and electricity usage.
- Displays four levels of air quality
- Identifies odors, dust and allergens
- Auto mode automatically adjusts settings based on pollution levels
- Replace filter indicator
- Maintenance Indicator reminds you when to clean the metal dust collector
7 proven air-cleaning stages for virtually every pollutant type
Captures Dust, Allergens, Mold Spores and other Particulate
True HEPA is the most effective type of filter at capturing dust, allergens and other physical particles.
Electrostatic Dust Collector Grid magnetically attracts particles and pollutants to metal plates. This adds another level of dust and allergen protection. Simply wipe clean when dirty--no replacement required.
Pre-Filter removes larger debris, increasing the effectiveness of the high-efficiency filters downstream.
Neutralizes Odors, Chemicals, Bacteria & Cigarette Smoke
Activated Carbon is the most effective filtration type against chemicals and odors.
Photocatalytic Filter takes care of VOC's and bacteria. Photocatalytic filtration has proven to be effective in multiple studies by the U.S. Dept. of Energy.
Produces Negative Ions, which help neutralize dust, allergens, chemicals and bacteria. Negative ions have proven to be both safe and effective in numerous government and university studies.
Destroys Germs and Viruses
Germicidal UV lamp is lethal against harmful micro-organisms. Recommended by the CDC (Centers of Disease Control).

Covers 500 square feet which makes it suitable for large living rooms, dining rooms, family rooms, office areas and basement. Seven leading air purification technologies: Pre-filter, electrostatic dust collector, true HEPA filter, activated carbon filter, photocatalytic filter, germ-killing UV lamp, negative ion generator.
The Intelli-Pro Air Purifier uses comprehensive sensors to automatically monitor and control air quality in your home or office. Featuring seven air-cleaning methods, the Intelli-Pro removes airborne toxins, allergens, dust, and odors to produce a cleaner, healthier environment. The Intelli-Pro features a long-lasting HEPA filter that has a proven 99.97% collection rate, and it has a built-in diagnostic sensor that alerts you when the filter needs replacing.
Quietly purifies air in areas up to 600 square feet. View larger.
Whether you need to remove allergens or odors from your home or office, the Intelli-Pro is up to the task. While other air purifiers use two or three types of filtration, the Intelli-Pro Air Purifier uses seven: a HEPA filter, an activated carbon filter, an ionizer, a photocatalytic (TiO2) filter, a germicidal UV lamp, a washable pre-filter, and an electrostatic dust collector.
The Intelli-Pro's HEPA filter is proven in clinical air chamber tests to remove 99.97% of airborne particles in areas up to 600 square feet. The activated carbon filter is effective against chemicals, odors, and cigarette smoke, and the UV lamp kills bacteria and other microorganisms. The Intelli-Pro's reusable collector grid uses magnetic force to trap pollutants and help lengthen the life of the other filters.
Sensor Technology Removes Guesswork
With the Intelli-Pro, there's no guesswork, just clean air. The Intelli-Pro's unique self-monitoring system gives you instant, easy-to-read feedback about the purifier's performance. A Clean Air Monitor uses indicator lights to let you know how clean or polluted the air is. Additionally, odor, dust, and allergen sensors tell you exactly which pollutants are present in the air, an ideal feature for those with allergies.
And thanks to the Intelli-Pro's Filter Indicators, you'll never have to worry about forgetting to clean or replace the filters. The indicators illuminate when it's time to clean the metal dust collector plate or replace the HEPA filter or activated carbon filter.
Quiet, Efficient Operation
The Intelli-Pro lets you enjoy purified air without noise pollution. The quiet setting provides nearly silent operation, while the high setting provides boosted performance without a lot of noise.
As efficient as it is quiet, the Intelli-Pro has a low-volume fan and multiple air inlets for maximum airflow. Additionally, sensor technology automatically adjusts the purifier's settings to reduce energy consumption.
The Intelli-Pro comes with a 30-day risk-free guarantee. Within 30 days of purchase, if you're not completely satisfied with the purifier, you may return it for a full refund. If you decide to keep it, the Intelli-Pro is backed by a three-year warranty on defects in materials and workmanship.

Top customer reviews
There was a problem filtering reviews right now. Please try again later.
It arrived a week after purchase in a custom box with the picture and information on the outside describing the product. Inside wrapped in plastic and Styrofoam sat my new Intelligent purifier. Make sure to follow the manual ( which can be kinda vague in set up) upon unboxing to set up the "auto" mode correctly.
"Auto mode" Setup; Unbox, place in room where is will be used. Set on High for a 2-8 hours with windows open if the air is really polluted. After the air has been cleaned to desired quality, turn unit off. Unplug for 30 secs, then plug it back it. All the lights will flash, then power up the unit (which is most likely on High still) the odor light will blink for 3 minutes, taking a baseline odor sensor of the surrounding air. Once "odor" stops blinking it has determined the air around the unit is considered "clean" and will use that as a baseline for odors. Now simply press Flow to "Auto" and its now sniffing the air to determine the fan speed automaticly. Note: Everytime you unplug, (such as cleaning the filters) you will have to reset the memory so the computer will know what clean air is. Also after a day or two, the sensor will get more sensitive.
Besides the unboxing setup, this system is plug and play. Its 4 different fan speeds give you plenty of control to determine noise factor. Even on High Its not a annoying and could continue a conversation 6ft away just fine. The machine is smart, telling you when to clean the Electrostatic Filter as well as the Carbon/Hepa Filter.
After Unboxing for the first time I took the unit apart down to the fan. Other reviews said it was difficult to take apart or clean the filters. If you have 15 minutes, some common sense, read the manual cover to cover, watch a few youtube videos of this unit or the "clones" being cleaned you will have no trouble. Also this machine is interesting with all the air cleaning technologies i just had to check out all the pieces before start-up. Yes it has quite a few pieces with all the different cleaning technologies and will take some maintenance to take care of your investment but I wanted a fully loaded air purifier and I got it.
Performance: The unit does clean the air very well and I am Satisfied with the job it does. It has only been a week but it is exactly what I wanted. I live with a small dog and a stubborn smoker that smokes inside our Two Bedroom (1000sq/ft) Apt. I wanted a premium purifier for my bedroom and to help with the stale air inside. During the day i run the unit at Medium with my door open in my "14x14" bedroom, then Low at night. If i choose to Ill kick it up to High but medium does a great job and the noise is below a quite conversation (High is avg conversion level.)
I place the unit at my door entry, 3 feet away from myself and electronics. Also between me and the smoker in the living room. The Auto sensor is not quite as sensitive as i like it to be, which is why I manually set it and forget it. I found about a 4-6 feet radius around the unit to detect farts and dust. For smoke just has to be in the same room, but i wanted the purifier more in my room so the door entry is middle ground.
The Customer service is great, they answered all my questions. Just shoot them a email or call between 10-2pm mountain time. They sent me out a new odor sensor and board to see if that makes the sensor any more sensitive. All free which is part of the 3 year warranty that you get.
All in all, the product is as described and does what i need it to do. It's a premium air purifier with all the different technologies packed into a knee high unit that doesn't take up a lot of space. Its affordable to operate, can clean the whole unit and filters minus the $35 Carbon/Hepa combo(which could get 3-12months out of depending on use.) For $199.99 + free shipping you can't beat this system that could keep up with $500+ systems. 5 Stars.
(UPDATE: After after 3 weeks of having the unit running, I am still happy with it. I got in touch with the customer service again to check on my free replacement dust + odor sensor + motherboard. They are shipping it out monday because they had to tear another unit apart to send me a replacement fan blower wheel. Mine is slightly off center and I will be opening up the whole unit to replace the odor sensor and motherboard combo. Makes sense to replace the blower as well. All free and under warranty but still has been 5 business days to send it out. But I understand and their honoring the warranty so I can wait just fine. As for performance, its still doing a good job and the air is way cleaner that's for sure. I looked at the pre-filter through the face plate and its getting full of pollution. I run on Medium through the day and Low @ night when im sleeping in the bedroom. I love having 4 very different fan speeds plus Automatic detection. I live with a smoker and you have to place the machine very close to the odor or pollution. About a 4-6 radius around the unit for farts and dust, smoker has to be in the same room. But that's the point of the replacement sensors ill be receiving soon, to see if those are more sensitive. I'll update again after install.
You do have to be careful when cleaning the unit, like other reviewers have said, the Tabs on the face plate are plastic and have to be take care opening and cleaning the unit. Its pretty standard plastic and construction from anything made in china though. Just take your time when coming in contact with the unit such as cleaning it. Don't be in a rush and don't force anything. I've taken mine apart once a week so far just to see dust and also curious on how the gusts are doing after 24/7 use. But for the $200 price tag i think you get what you pay for and more. The performace is of a $500+ machine but that comes with some budgeting else where like the tabs on the face plate represent a $200 budget air cleaner. If you take care of the delicate parts youll get 5 years out of it at least.
Also Did AMP draws on the unit for each setting and it could be energy star certified.
HIGH - 0.44 Amps
MED - 0.34 AMPS
LOW - 0.27 AMPS
QUIET - 0.21 AMPS
AUTO - 0.18 AMPS
To figure out how much your devices cost to run, see these formula:
Watts = Amps * Volts
Kilowatts = Watts/1000
Kilowatt-hours = kilowatts * Hours used
Cost = kilowatt-hours * cost per kilowatt-hour
Cost = (((Amps * Volts)/1000) * Hours Used) * Cost per Kilowatt
You could also do like I did and split an old extension cord (so you can clamp on to a single wire), then plug one end into the wall, and your device into the other end. Then you can measure the draw of just that device.
Running this unit on HIGH in my local area @ $0.12 cents a KWH , only cost me $4.56 to run 24/7 per MONTH. LESS THAN $5 IN POWER TO HAVE CLEAN AIR per month. Sounds good to me. END. )
(Update 2 : I Received replacement parts in the mail. The packaging was the same before.They also sent me the whole back chassis w/ blower motor. I installed a new odor sensor + motherboard, Dust sensor, and replaced the back chassis + blower wheel. It was very easy with a simple standard Phillips and flat screwdriver, just make sure their dedicated tools( no multi bits, The two screws on top are embedded a few inches down and no multi drives will fit.) After resembling and following start up protocol, I switched the unit into "Auto" mode. Waited for my roommate to smoke in the living room, that connects to my bedroom where the unit spends its time. Sure enough "Dust" and "Odor" LEDS light up to kick the fan into "Medium". I really like how they designed the unit to go to Medium and transition down to "Quiet". Fan Speed is still in "Quiet" even when in ''Auto" just the LED turns to "Auto". Going to HI setting automatically every time would not be comfortable noise level, Say at night when your sleeping. Replacement sensors solved my problem and it works like a charm now.
The new Blower wheel was attached to a new chassis for easy install. All I had to do was drop the guts of the old unit and place them into the new chassis when i put the motherboard. Though once reassembled the new motor or wheel was off balance, which gave the unit a wobble. So i just unscrewed the six screws to drop the guts back into the old chassis with original blower. My original one is off slightly but its only to the eye looking at it spin. It is still silent and has zero vibration. I was just going to try to prevent a problem down the road.
Besides that the unit is operating as it should and I'm still happy with the purchase. The 3 year warranty they give you covered all the replacement parts I had them send me. Customer service was helpful the whole way. I recommend this product based of my experience so far. )

When I look at reviews to buy a product, I don't read all the 4 and 5 star reviews because I'm thinking most people are too proud to admit they bought something that doesn't work... you feel better about your $200 purchase when you tell everyone else, "It's wonderful!" No, what I do is click the sort button to show me the 1 and 2 star reviews because I want to hear what the unhappy buyers have to say. For this product, the 1 and 2 star reviews represent about 15 percent of the total number of reviews, and 78% represent 4 and 5 star reviews. Apparently, not a bad product according to customer reviews.
In the bad reviews I read things like,
"...it gives off a foul burning plastic smell when you first turn it on...", or
"...the 'AUTO' mode doesn't do anything when I shake a bunch of dust in front of the intake vents...", or
"...the 'clean metal grid' and 'replace filter' lights come on much faster than hoped or advertised", or
"...I am a senior citizen and I broke the metal wires trying to clean them...".
And then there were those who warned that you'd be sorry if you bought the item because all the positive reviews fail to tell you certain things which are important about this horrible product (in their opinion)!
I just about decided not to buy the XJ-3800 Intelli-Pro based on what I was reading, but in all fairness I scoured through the 4 and 5 star reviews. I wanted to see if there were enough people giving intelligently informed opinions rather than just stating that they loved it and that it has a bunch of bells and whistles that seem to indicate that it's working. After much reading, I allowed the positive reviews to help me overcome my skepticism and purchased the unit.
My unit arrived in less than a week. Upon unpacking the unit, I remembered that almost everyone expressed a little bit of surprise with the size of it. With me, I'm thinking, if this unit is going to take care of a 20 by 30 room (600 sq. ft.) and be able to do so quietly and efficiently, it's going to have to be larger than your typical bookshelf speaker; otherwise it's just not going to be efficient or fast enough at cleaning up the air when contaminants are introduced (smoking, odors, pollen, mold, etc). Now engineering physics tell you that you can do the same job with a smaller sized unit, but then you have to have a faster fan speed to move the same volume of air. Faster fan speed would translate into more fan noise, so I guess the trade off here was to go a little larger in size and opt for quieter operation. I'm good with that.
For the operating display, the unit has a power button, and an airflow control switch which can be set to AUTO, QUIET, LOW, MED, and HI speed. The AUTO mode allows the unit's sensors to determine the necessary fan speed based on the quality of the air in the room. The sensors are suppose to throttle the fan speed up and down accordingly as needed to clean up the air. The display also has a 4-light indicator labeled, "Clean Air Monitor" which is interpreted as follows: 1 light on - no pollution detected; 2 lights - some pollution detected; 3 lights - moderate pollution detected; 4 lights - severe pollution detected. Next there is a UV/Negative Ion indicator lamp which just simply tells you the UV lamp is working. This UV indicator light is suppose to cycle faintly between dim and bright. Many people have complained that the light is an eye sore and cover it with black tape if it is being used in the bedroom where they sleep. Personally, I found it no more obtrusive than a very dim night light or the LEDs on your cable or satellite DVR. The light oscillations were very faint such that you really don't notice it unless you intensely stare at it. Next it has sensor lights for ODOR detection, DUST detection, and ALLERGEN detection - pretty straight forward. It also has a Power ON timer, which can be set to 1 Hr, 2 Hrs, or 8 Hrs. I think I would have rather seen 2, 8, and 12 hour timer choices for my needs. And finally, there are indicator lights that tell you when to clean the metal grid filter and when to replace the HEPA filter. No doubt this is a thoroughly designed unit if everything works properly.
I have had the unit now for about 2 weeks, and the following are my impressions after using the air purifier during this short amount of time:
First, the instructions clearly say to place the unit in a large room initially where you can create outside fresh air exchange by opening windows and doors assuming the outside air is relatively clean. You are to operate the unit for several hours in that room before using it in its intended space. I suppose this is to help alleviate any potential smells from the unit while it is new and freshly unpacked. But the interesting thing is that the unit I received did not seem to have any objectionable odors during initial operation, even when I bent down and sniffed the purified air exhaust in the back of the unit. Well that's all good, but why are other buyers saying different? My presumption is that probably 5% of the units sold have a problem due to quality control, in assembling or packaging resulting in unusual off-gassing. Asking for a new replacement unit immediately if this occurs would solve that problem and that is where Amazon shines.
During initial operation in "AUTO" mode, I began to worry that this unit was more of a conversation piece rather than an air cleaner because of all the pretty lights, buttons and futuristic looks. I worried that the unit was doing nothing more than acting like a small air blower. So I decided to get out our 12 year old vacuum cleaner and started vacuuming in the area near the purifier. Within less than a minute, the "DUST" light came on, the clean air monitor indicator moved to 4 lights (indicating severe pollution detected) and the fan speed immediately shifted into "HI". The fan noise was not objectionable; in fact not even near as loud as a normal oscillating house fan running at a moderately high speed. With bright sunlight light coming in thru the large living room window, I could see particulate dust matter floating around in the area where I had just run the vacuum. Within about 5 to 8 minutes, the particulate matter had cleared and the unit began to cycle back down to "MED", then "LOW", and then the "QUIET" fan speed. At that point I was thinking, hmm, nice!"
I had remembered reading one fella's review who wrote that when he expelled some personal gas near the purifier, he laughed when the "ODOR" light came on. I thought, funny, but naaaah. So I went to take a shower while the unit was in its initial operation for several hours. When I got out, I decided to take my roll-on deodorant and apply it to my underarms while near the purifier. Sure enough, the "ODOR" light comes on (I assume from the deodorant `cuz I'm not gettin' back in the shower, lol), the fan speed ramped up, and stayed this way after I had left the room and gotten dressed. When I came back 15 minutes later, the odor light was still on but I ignored it and left the room again. Came back about 2 or 3 minutes later as I was leaving the house and the "ODOR" light was now off and the fan speed was back to "QUIET".
Now just to give you a little heads up, neither my wife or I are smokers, and we don't have any inside pets, but we do live in an area of the country where outdoor mold spores and pollen counts can rise moderately high at times. Our home is only about 12 years old, and we mostly use a propane ventless space heater to heat our lower basement office areas in the winter. This is where I spend most of my days and where I want to use the purifier.
Well after initial operation, the instructions say to unplug the unit from the wall in order to reset the sensor data memory and move it to the space of intended use for normal operation. I did this. After plugging the unit back in and powering up, the unit shifted into "MED" speed and the clean air monitor lights went to Defcon 2, lol. I guess it was finding that my office space had contaminated air. As an interesting contrast on the odor detector, my wife decided to do her fingernails one evening in the room next to my office. The chemical was that strong smell of acetone fingernail polish remover, which permeated the whole downstairs. I closed my office door and looked over at the XJ-3800 Intelli-Pro and it had already ramped up to the next to highest fan speed, with 4 lights showing on the Clean Air Monitor, and the ODOR light was on. It took the unit about 10 minutes to clean up the air in my 15 by 15 office with the door closed. When I again opened my office door, the unit ramped up again to clean the rest of the air in the basement area. It finished that area in another 30 minutes.
I have to say that I am pleased with this unit and would buy it again with the short experience I have with it. I am not sure what kind of life I'll get out of the UV lamp, HEPA filter, or "wires" that will eventually need to be cleaned, but the instructions give you step by step procedures with pictures so I am not too worried. Now what about all the other good folks out there who have not had a positive experience? Well the discernment that I believe is needed here would include the following:
* Do you have a highly contaminated interior area that includes, frequent smoking, indoor pets, damp and musty basement areas, older construction homes (20 plus years), carpet or upholstered furniture that has not been replaced in more than 10 years, wood burning fire places where ashes and soot can become airborne, inadequate outdoor air exchange rates (ASHRAE codes recommend a complete fresh air exchange through mechanical ventilation every 3 hours, minimum)? All of these can create an interior space that will require an air purifier to work harder and longer, and shorten the life of the filtering system.
* If your home is naturally ventilated from open windows, screen doors, loose door and window seals, etc. then your home will experience 3 to 5 air changes per hour or more. If you have high mold spore and pollen counts outdoors, high humidity levels, high industrial or transportation pollution nearby, and windy conditions, this can be bad for the inside of your home and can shorten the life of your purifier's filters.
* Some people (and I really should say most people) don't like to read instructions. They unpack a product, plug it in, and then throw their hands up in the air when it doesn't work the way they had hoped. A good manufacturer includes helpful instructions to make sure you have a successful experience with their product. They know that if the unit works properly, you will tell your friends and you will buy another. Therefore, they go to great lengths to tell you how to get the best operating experience out of their product. Read the instructions before turning the unit on. I think this may be the downfall to some, not all, who experience disappointment with this unit.
* And finally, some of these units probably are lemons out of the box. Based on the reviews, and taking exception for operator error, I am guessing the lemon rate may be as high as 5 percent. That's probably 4 percent too high. But even with this high of a faulty rate, Amazon will be your ace in the hold to insure your satisfaction.
Therefore, I have given this product a 5 star review and would recommend all to buy it from an Amazon sponsored dealer in order to protect your purchase.
