The so-called recent air system extracts the outside air by means of the pipeline and filters by way of the machine to enter the room. On the similar time, the brand new air blower will make the indoor air strain barely bigger than the outside, and the indoor air will slowly leak out by means of the hole to realize the aim of purifying and circulating air.
To make an analogy, automotive air conditioners have two modes: internal circulation and outer circulation. The inside circulation is like an air air purifier, which purifies and circulates indoor air in a confined area. The outer circulation is sort of a recent air system that pulls in and purifies the surface air.
Within the precise use, the air air purifier has a superb purifying impact in a confined area. However when individuals are in a closed setting for a very long time, it’s straightforward to trigger indoor hypoxia and extreme carbon dioxide. If the fog is caught up, it’s unrealistic to open the window. With the recent air system, you’ll be able to full the air flow with out this hassle, eradicating the cockroach on the similar time. As well as, because the indoor air strain is barely larger than the outside, the outside polluted air enters. So these methods are additionally useful to the discharge of dangerous substances akin to formaldehyde.
The disadvantages of the recent air system are excessive value and troublesome set up. The entry-level merchandise are priced over 4 or 5 thousand yuan, whereas the high-end fashions value round tens of hundreds and even a whole lot of hundreds. Furthermore, the upper the merchandise, the upper the set up necessities.
So if summarize the present issues of the recent air system, we will say that they’re costly, have to make a comparatively giant modification of the home, and eat a lot electrical energy.
The time for Xiaomi to enter the empty subject isn’t too brief. Since 2014, a collection of merchandise together with air purifiers, automotive air purifiers, masks, and different air high quality merchandise have been launched.

Due to the robust correlation with the acquisition and the ornament seasons, and the excessive worth, there’s all the time a really small selection of this type of merchandise and it’s principally unique to native tyrants.
The Mijia new fan that we’re reviewing belongs to the class of a single fan. It adopts the wall-mounted design. It solely must be punched on the wall. After set up, it may be related to the facility provide. The set up value is far decrease than the central recent air methods.
Because the place we’ve got skilled has already put in the Mijia new fan, there isn’t any solution to elaborate on the detailed set up course of. In truth, the Mijia new fan is like an enlarged Xiaomi Air purifier Professional, and the official doesn’t present too detailed dimensions. From the visible perspective, the dimensions of the Mijia new fan is just like that of the generally used wall-hung boiler within the residence. So long as there are sufficient distances on each side of the window, it may be put in. As well as, in accordance with the official introduction of Xiaomi, Mijia new fan helps quite a lot of set up strategies together with glass opening, which eliminates the consumer’s affect on the wall to have an effect on the unique inside ornament or property.
Briefly, for almost all of customers, the set up of Mijia new fan won’t be an impediment. You must take note of different issues – is your bed room hanging an identical factor to the fireside? Is it acceptable? Additionally, you need to minimize a gap within the measurement of your bowl in your wall.
Objectively talking, the worth of the Mijia new fan shouldn’t be dangerous, nevertheless it has no particular options in design, and there’s no slot. It’s appropriate for matching ‘cold and modern’ type ornament.
The outer casing is made from the identical engineering plastic because the Xiaomi air air purifier. The matte texture is straightforward to wash. The secret is that it’ll not yellow when used for a very long time.
Beneath the fuselage, there’s a emblem of Mijia. The center a part of the fuselage carries an OLED touchscreen. The air situation might be intuitively understood from the numerical worth and the outer aperture. On the left aspect of the display, there’s the sunshine adjustment button, and the appropriate aspect has the facility change/mode choice button. It’s principally the identical because the operation logic of the Xiaomi air purifier.
On the fitting aspect of the fuselage, there are three sensors of PM2.5, CO2, and temperature/humidity. The Mijia new fan makes use of Swedish imported Senseair’s CO2 sensor and Plantower laser PM2.5 sensor, permitting customers to view indoor air high quality knowledge in actual time by way of the Mijia App anyplace.
For brand spanking new followers, it is rather necessary to vary the filter. In any case, the filter is a consumable. If it isn’t changed recurrently or it isn’t straightforward to wash, it won’t obtain the impact of air flow however could have negative effects.
The Mijia new fan adopts a triple filter construction: anti-mosquito filter, medium-effect filter, and H13 high-efficiency filter. The anti-mosquito filter adopts a mesh field design, which may be washed instantly with water with out changing the consumables.
The second layer is the medium effectivity filter. The official removing price of PM0.four is 80%. Pollen, smoke and so forth shall be blocked by this layer. A lot of the PM2.5 will cease right here.
The final layer is the HEPA13 high-efficiency internet, which may filter PM0.three, together with some micro organism, germs and so forth. After layer filtration, it’s principally assured that the air getting into the room is protected and clear sufficient.
The operation of changing the filter materials can also be quite simple. The three-layer filter display is designed on the entrance of the fuselage.

Whether it is used constantly, Xiaomi recommends the medium-effect filter to get replaced as soon as each three months, and the high-efficiency filter ought to be changed as soon as each 6 months. The mosquito display might be cleaned based on the state of affairs.
In keeping with the precept of different single air blowers, the Xiaomi recent air system additionally depends on the precept of supplying air into the home and manufacturing indoor micro-positive strain for air change. The impact is equal to opening the window beneath the situation that the outside air is extraordinarily clear, and the air outlet is within the fuselage. On the prime, this operation mode could be very useful for the dissipation of persistent risky gases corresponding to formaldehyde and TVOC. Though conventional activated carbon may also adsorb such substances, as soon as it’s saturated, it loses its impact, and the general impact isn’t on the order of magnitude with the brand new fan. Subsequently, for newly renovated houses, using new followers is extra advantageous than different merchandise.
How concerning the purification impact?
In fact, though the set up is straightforward and handy, an important factor is to truly use the impact. (Word: The following check knowledge is offered by Xiaomi official.)
The setting we examined comes with a complete space of about 100 sq. meters. The Xiaomi recent air system was put in in the main bedroom and the world was about 18 sq. meters.
Air quantity is usually a direct issue affecting the relevant space of recent air, purification velocity and so forth. It’s also one of many efficiency parameters that individuals are most involved about. Popularly talking, it’s the quantity of air measured on the air inlet, which refers back to the quantity of outside recent air getting into the room each hour.

The air quantity of the Mijia new fan is 300, which is a comparatively mainstream degree.
First, let’s check the focus of carbon dioxide. In contrast with PM 2.5, the hurt of carbon dioxide is often simpler to disregard. When the doorways and home windows are closed, the indoor air can’t be replenished, and the carbon dioxide will accumulate slowly and the focus will turn into greater. There’s a set of knowledge right here that feels uncomfortable when the carbon dioxide focus exceeds 1000 ppm.
1. 350~450ppm: similar as the overall outside setting;
2. 350~1000ppm: recent air and clean respiration;
three. 1000~2000ppm: we really feel the air is turbid and begin to really feel drowsy;
four. 2000~5000ppm: Feeling headache, lethargy, sluggishness, lack of ability to pay attention, speedy heartbeat, delicate nausea;
5. Larger than 5000ppm: Might trigger extreme hypoxia, inflicting everlasting mind injury, coma, and even demise.
Via a collection of painstaking operations, the indoor carbon dioxide focus efficiently reached 4646ppm, and the Mijia new fan was opened to the very best degree for 30 minutes, the focus of carbon dioxide was decreased to 471ppm, which was transferred to a very good state.
TVOC can also be very dangerous to the human physique. TVOC is a common time period for indoor risky natural gases aside from carbon monoxide, carbon dioxide, carbonic acid, and carbonate.
From the precise check, at 15:17, the TVOC focus reached three.52 and exceeded the usual. The highest degree was opened, and the rating was lowered to zero.578 at 15:49. The entire course of took about 30 minutes.
It may be seen that the Mijia new fan continues to be very efficient in eradicating TVOC as a result of it’s the simplest solution to cope with this steady volatilization of fuel. So the brand new fan progressively brings TVOC to the surface in indoor and outside air trade. It’s vital to put in a recent air system in a renovated home.

Earlier than opening, the indoor PM2.5 index reached 514.1?g/m3, which was a critical air pollution degree, and dropped to zero.1?g/m3 after 20 minutes.
Is the noise loud? Is it fairly costly?
Noise and energy consumption are additionally essential elements. Within the noise half, if the very best degree is turned on, the noise continues to be very apparent and principally can’t be tolerated.
Nevertheless, the Mijia new fan mechanically adjusts the air provide quantity in line with the indoor air high quality. There’s additionally a sleep and favourite mode.

There’s virtually no noise within the automated mode, which is right for all-weather operation.
The excessive energy consumption of the Mijia new fan is just 35W. After accounting, even whether it is open on the most gear all day, it solely consumes about zero.84 kWh in 24 hours.
Nevertheless, it’s essential to specify that the Mijia new fan is provided with an electrical auxiliary warmth perform of as much as 800W within the third gear. When the electrical auxiliary warmth perform is turned on, the working energy of the Mijia new fan is 335W, 535W, and 835W, respectively. When utilized in winter, the facility consumption continues to be a bit excessive.
The final query is, is it a brand new fan or a air purifier?
- a) Take a look at the world. The recent air system has restricted area for purification. So a small condo or a separate bed room is sweet. A lot of the homes are extra appropriate for purchasing a number of purifiers.
- b) Take a look at the demand. The recent air system is best suited for set up in a newly renovated room, which may shortly and successfully take away dangerous substances of formaldehyde whereas purifying the air. The previous homes differ from individual to individual.
Taking the air high quality drawback as a chance in recent times, the air purifiers have grow to be a well-liked class. In additional households, enterprises and even service locations, we will see many air purifiers. In distinction, recent air merchandise have all the time been tepid out there. Amongst them, the chaotic pricing of 4 or 5 thousand and even almost ten thousand yuan is a vital purpose to maintain consumers out. Just like many industries which are within the lead-in interval, the brand new wind business additionally wants an economical and in style product to really activate the market.
The worth of the Mijia new fan shouldn’t be excessive, the set up is straightforward and handy, and the edge of the recent air system is lowered to some extent. When you have a big inhabitants and ample set up area, the two,000-yuan Mijia new fan is value contemplating.
