The Surround Air XJ-3800 Intelli-Pro Air Purifier is among the high end air purifiers that use several sensors to monitor the air quality and make changes to the purification process accordingly. The machine looks futuristic from the front, as it should considering the digital technology it uses but from the side, it is rather bulky as the vents are on the side and top. The XJ-3800 has a great finish to it and it is the type of air purifier that you will want in a minimalistic room or study.
The XJ-3800 features six types of filtration processes at various levels to ensure that the air it sends out is as clean as possible. In fact, this machine can be compared to the clean rooms used in small scale laboratories. The types of filters used here are the pre-filter followed by the activated Carbon filter, which is supported by the HEPA filter. These are all working in tandem with a UV lamp, an ionizer and a dust collection grid. While the first three are common to most lower end air purifiers, the latter three are what really make the difference.
The UV lamp is aimed at killing bacteria and other microorganisms that get away easily. The radiation is dangerous to them but Surround Air XJ-3800 uses only minimal doses so you have nothing to worry about. The ionizer is used to crush the dust particles to smaller pieces to ensure that they can all be eliminated with ease by the dust collection grid that uses electrical potentials to segregate the particles and collect them.
The other notable feature of this machine is the use of various sensors that work all the time to monitor the air for levels of pollutants and the like. Based on this the machine adjusts itself to the right power for optimized cleaning. This can be bypassed by the manual control of the fan speed but it is best to let the gadgets do it for themselves. Moreover, the use of these sensors ensures that the machine uses just the amount of power it needs and nothing more. In addition, there is a display that lets you know exactly how clean your air is. There are also sensors and displays for odors, dust and other allergens too. The most useful indicator is undoubtedly the one that tells you how full your air filter is and when it has to be cleaned. Note that the HEPA filter is permanent and needs vacuuming only about twice a year, which is very economical.
The machine also has a great sleep or quiet mode setting that makes almost no noise. This is ideal for the night especially in the bedroom if you need the air to continue circulation. The fan in the machine is also low volume but this is made up with the number of air inlets. Together they work to reduce the power consumption of your machine and maintain its efficiency.
Surround Air is pretty confident of this machine’s quality that it offers a risk free guarantee of 30 days where it is willing to refund the whole of the amount if you are not happy with the machine. In the testing period, there were no noticeable flaws with the machine but some customers had problems with the UV filtration, which were immediately replaced. However, do check the dimensions of the machine carefully before purchasing as you might get something different from what it looks like in the photos.
