Another question - what kind of thread is saved in MiHome? shows only the current value and everything, although there are some rudiments of the graph.

There are projects on githubs like this:
https://github.com/aholstenson/miio

theoretically, based on them, it is possible to assemble a collector of indicators into the base in a couple of hours, and then attach a web-face to this base. but I'm lazy ;)

* edo1,
There are different levels of filtering and yes, most often they are denoted by numbers, not colors, but even HEPA is of different levels.
In our case, the more expensive the filter, the greater the level of filtration.

asked the sellers - they say that the green filter is better for filtering odors, etc. - there is corny more activated carbon
antibacterial is not at all clear why it is needed (so that all kinds of things would not start in a filter in a tropical climate?)

We animate the topic.

Like I need this device, I'm allergic, including house dust. But I'm afraid to buy, as it is not clear in the future where to get the filters. Develop my fears plez



Taki bought Air Purifier 2. Very interesting thing. I live on a busy street, yesterday I opened the window - it stinks, the cleaner immediately reacted and increased the power. Smells are gone.

In general, the level of pm2.5 is somewhere between 20 and 30, with the window open - 30-40. In the future, mb will write a program to collect statistics based on it

P.S. Zapilite someone navigator on the sale of replacement filters, differences replacement filters. Well, by the device itself, a comparison tablet would not hurt.

At Gearbest, if you take a filter, the cheapest is obtained, and if you also get a package offer (buy it plus this and that) then it is even cheaper.

Purely share your impressions. The device of the first generation, in use two months, the filter is spent for 12%. The level of RM 2.5 on the worst day (cleaning, airing, etc.) did not exceed 75-95, but the device quickly and practically without noise ensured proper comfort and safety))), but "strongly recommended" to increase the humidity level in the room. Humidity in the apartment is really low 17-20% (winter, batteries) there are separate humidity sensors. For this reason, and in honor of the holidays, an ultrasonic humidifier was purchased, stands in the opposite side of the filter from the apartment. It was after this that neponyatki began: sveta: The filter, without any significant changes in the apartment and the environment on the street, began to increase the level of filtering according to the algorithm specified earlier, the noise level increased accordingly. The evidence of the harmful particles rose before the eyes to a critical level for China 700-800, and the noise level began to annoy unpleasantly. Naturally trusting "smart" technology, we put up with noise, and it was during the holidays, all the houses and waited for the filter to save us from harmful particles. Indeed, the filter also gradually reduced speed and the level of particles returned to normal. However, by means of exceptions, and these miracles were repeated with the filter more than once, the source of the “unfavorable” conditions for the filter was revealed - Humidifier !!! As soon as the humidifier ran out of water, the filter reported a decrease in the level of harmful particles. It turned out nonsense! Increasing the level of humidity recommended by the filter and other sensors in the room, the filter assumes this humidity as a high content of pm 2.5, thus trying to "clear the air" from non-existent particles or simply reduce the humidity. The result was a struggle of opposites. A question for practitioners: who have both this gadget (ultrasonic humidifier), how do these two devices coexist? Or in the scenarios to divide the turn-on time of devices? Although what's the point after turning on the filter will detect increased humidity and will still try to deal with it: girl_cray: And no, anticipating the question of too close position of gadgets relative to each other, the filter and the humidifier are located at a considerable distance from each other, more than 4 meters and the fine water from the humidifier can not get to the filter sensor, breaking with the area of ​​the heated floor. Although as an experiment I will try to place the filter next to the bath after the procedures and will add and so long post.

* VladSVL,
Perhaps the water is not perfectly clean and impurities from the water enter the air.
Buy distilled water and try. (For example, in a pharmacy or in an auto shop).

* VladSVL,the same story as you.
It does not depend on the distance. Meter or more. From the ultrasonic humidifier model too. There is also a xiaomi and another.
I have two humidifiers and one of them at a distance of more than five meters and also increases the level of pm.
In general, the PM rises when the humidifier is working up to 300 or more units.
I do not know what to do. As a temporary outlet, my filter does not work when the humidifier is working, after always
the filter is working in the night mode, because in another mode the noise level is too big.

Ultrasonic humidifier may not be compatible with the filter?

* trx900, the humidifier sprays small droplets of water that hang in small particles in the air, the filter cannot distinguish these drops from dust and cleans the air.
He does everything right.

In the filter there is not a particle analyzer, but a laser that detects the presence of any particles in the air. Steam is water in the air. For him, it is pollution.

* tribal2008,well yes! laser?
I do not even know how to respond to such a statement.

* monte1977,and this is all clear.

The nature of the phenomenon has been clarified.
The question is: how to operate together an air filter and an ultrasonic humidifier?

* trx900, together in any way.
Air enrichment is possible due to evaporation through the air washing will work, but I can not guarantee, we need tests or someone else will say.

Thanks for the comments, especially constructive. However, the question to the manufacturer remained. If Xiaomi positions its products as a “system”, then the filter and the humidifier, as representatives of this system should complement each other, well, not how not to fight each other. After two days of trial and error, a pattern was found that the filter begins to “struggle” with humidity after 30-35% of the average in the room. At the same time, the humidity should grow very slowly, that is, the evaporation process (disintegration into small molecules (size 0.30 nm) of fine water from the ultrasonic humidifier should take place until the water dust reaches the gas analyzer built into the filter, which in turn detects particles 2.5 nm in size. And it cannot determine the molecule itself because of its insignificant size. I expose the first intensity level so far. Nowhere does Xiaomi have any restrictions (instructions) on sharing a filter and a humidifier, then there is a theory that co-dispersed water can a priori capture (bind) harmful particles smaller than itself (2.5 nm.) by binding them and precipitating, thereby also fighting for the cleanliness of the air, it has long been known that there are less harmful particles in humid air. In theory, xiaomi engineers could not do not know and, as an option, do not impose restrictions on the operation of the filter and humidifier, because they, in theory, complement or, alternatively, enhance the ability to clean the room through various methods of dealing with dust! Then it is clear the distinction between filtering elements and antibacterial (for humid (tropical areas) or rooms with high humidity), ordinary and improved (with greater odor absorption). Or am I wrong?

Purely for the sake of curiosity - buy 5L of distilled water in Auchan and pour it into a humidifier. Well, what if :)

* monte1977, There is an air wash with natural evaporation and a Xiaomi analyzer. There are no problems, they work together.

* VladSVL,I fully agree with you in terms of the additions of devices in a smart home, and not "fighting with myself."
More than that, on all the pictures in the advertisement, these two devices stand side by side, literally complementing each other.
VladSVL @ 03/13/18, 18:10*

A good idea, of course, is to try, but the sensor in the filter is not in the cartridge, so I think that the filter will react equally as independent
from any of the three types of cartridges installed in it.

Wash, yes, it should work differently, I ordered such a new one from xiaomi that it came out recently, but it will not be soon, and this will not solve the problems of our discussion.
And the air wash, it does not so much moisten the air as an ultrasonic humidifier. All the same, different devices on the principle of action.

I did not reveal the dependence on water quality. Poured water from both the tap and from two different filters, one of which in new cartridges, is guaranteed to remove everything.

No, it's not about the sensor in the filter, but about the users who operate the devices. They must decide on the choice of filter for the room where and with what in a pair it will be used. But the fine water from the ultrasonic humidifier clearly affects and no matter what sources it is from. This is so to say a kind of air wash. That's just our speculation, or there is some kind of manual from the Chinese.

To decide this, yes, but how to exploit it in such a noise? What are we missing, only to understand what?

I suggest not to guess, but to write in support of Xiaomi. It is better to duplicate letters to the European address and to the Chinese. You need to write in Ingl. well, or Chinese, if you know. Describe the problem. They answer in different ways, but they didn’t answer me from the European department, but Shanghai answered (addressed to the Miband account). Chinese bastards answer))
