Against the haze, the air purifier is not necessarily to spend expensive!
Various recent haze, many of my friends are buying advice Which air purifier fly. We generally use an air purifier, its working principle is passive. Simply put, it is to draw air into the machine, purified and then released.
If you have the space at home, the appearance is not so sensitive, there are ways to circumvent it slightly higher noise levels, FFU would be a substitute home air purifier affordable choice.
In layman's terms, it is said to be a commercial or industrial type air purifier, it has long been widely used in a variety of clean rooms, clean room and clean factory

在这个过程中，两个因素决定着空气净化的效果。
First, the velocity of the air suction and release, which is the amount of wind.The faster, the amount of air means that you can handle the greater in a given space, the same amount of time to deal with the higher frequency of air.
Second, the level of air filtration.The higher the level of filtering, the fewer pollutants released contained in the air.
Take laundry analogy, then, refers to the first aspect of the day was a wash or wash three days a distinction, it refers to the second aspect of the water or go over carefully rub difference.
Reflected on the air purifier,Are two core components: the fan and filter.Fan is responsible for the intake air, the air filter is responsible for filtering. Of course, both of which also affect each other, the higher the screen size, the greater the drag coefficient, is bound to affect exhaust volume, thereby affecting the efficiency of the fan.

Let's compare the FFU and common household air purifier distinction。
① | wind
FFU can reach 1200-1500 cubic meters per hour, and the air flow home air purifier are generally in the 400-500 cubic meters per hour.
What is this concept? Suppose your home interior area of 1200 square meters, the height of 2.8 meters, FFU air volume of 1200 when, in theory, can be done about every 17 minutes will filter the air in your home all over again. Common household air purifier, again this time is about 3 times.
②| Filtering level
FFU using a HEPA filter, are generally required to achieve even higher levels of H13, home air purifier relatively mixed in this regard, there is a higher level also has a lower level. However, H13 is certainly good enough for home this level.

▲FFUFilters and air purifier filters common household size comparison
Moreover, FFU used screen size is much larger than home air purifier. Large screen also brings a more lasting and effective filtering effect. Nominal filter dust holding capacity is 1000 grams, that is, you can pretend to be under 1 kg of dust, it was converted over, the home environment, the filter replacement cycle can be up to about two years.
Household FFU in use for about a year once again test: wind attenuation, but not obvious, the filtering effect is still no problem, is expected another year should be no problem.
③| price
General FFU priced at 800-1500. High-end home air purifier, the price at every turn five or six thousand, the million is not uncommon.
In addition, the price of home air purifier filters generally have five or six hundred, but as a mature industrial FFU, filters price is only 300 yuan.
In one hour three times indoor air purification standards, storey 2.8 meters, an air volume of the applicable area of 1,200 FFU can reach 142 square meters. That is, in theory, as long as a majority of families FFU enough.
Now we FFU according to the seller also specifically for the home market with a package, in addition to FFU, plus the early effect filters, activated carbon into account network, efficient protection filter diffuser and stainless steel mobile stand. So that the original only in FFU used in commercial appliances as much as possible to the image of truing.

Home air purifiers on the market compared to, FFU advantage of purifying effect is good, cost-effective. However, before we start, small or to remind you carefully consider the following questions.
④| volume
FFU generally available in two sizes, one is 1175mm × 575mm, the other is 575mm × 575mm, as for thickness, will have to install filters and other accessories, as the may be, but generally are not thinner than 230mm, thickness may be obtained It will reach more than 350mm.
The first specification, basically the equivalent of a little dwarf cabinet air conditioners, home when the general vertical, the second specification is more suitable for home when hanging. So, if the family had no space to put such a big guy, or careful consideration.
Now we are developing on the plant size is more suitable for home use FFU, but not the volume of adjustable space, in addition to the issue of special mold cost and other aspects, the most important reason is that, FUU as glass fiber filter material, drag large, the need to use a larger screen size to solve the problem of wind, difficult to do small volume.
⑤| noise
Our FFU distance of one meter, noise test result is minimum 49 db, a maximum of 55 decibels. Others test results are basically concentrated in the 40-60. Fan 2 is equivalent to the sound profile. In fact, it can be equipped with timed outlet.
⑥| Exterior
FFU industrial supplies, general clean in the construction of commercial space will be designed prior to their placement space for the home, we have been working hard.
