Dust and cold in the bathroom. Will replacing the grille help? Bathroom fans.

Hello,
I hope this is the right section :)

The problem is that the bathroom is very dusty. If I wipe the dust off, it's back the next day. Every time I hang the laundry, a lot of it comes out of the strings. I've cleaned up a bit recently, but it didn't help much. There was a lot of dust on the ventilation grille and inside. Also, it's probably the fault of the ventilation and the dust is flying from the chimney. What's more, it seems to be blowing too cold air out of it. i.e. normally when entering the bathroom it is not very cold, you do not feel it, but only after leaving the shower/bath you can feel the cold and you need to wrap yourself in a warm towel as soon as possible. I know that the reason may be the difference in temperature, but other people, be it family or friends, do not have this problem.

I currently have something like this grille. It has quite large openings.

The bathroom is small, maybe 5 m². There is a Junkers stove inside.
From time to time, the chimney sweeps do a review and so far have not had any comments.
Apartment on the 2nd floor in a 4-story block (supposedly this problem occurs often in apartments on the 2nd floor).

And the question: what to do so that it does not get dusty and is not cold? Will just replacing the grille help?
For example, for those with a sieve http://allegro

The one with the blinds might be good for the cold air coming in?

Oh, and I forgot that the bathroom door has ventilation grilles on the lower wing, through which cold air can also fly. What could I do about it? Can I plug them or will it be too dangerous?

I have one more question about bathroom fans. Would you recommend buying something like this and can I install it at all? I mean the cheaper ones for PLN 30-50.

Or maybe there is no point in playing it and just the grille is enough? Anyway, I don't know if I'll be able to install it anyway, because I'm green in these matters...

I would be very grateful for your help ;)

The strange thing is that air should come out through the grille and not cold enter. Check it with a lighter or candle flame. After applying the flame to the grille, the flame should deviate from the vertical towards the grille, which means that there is a draft to the ventilation duct, if the flame deviates from the grille, it is not good And it probably is, since you can feel the cold air and dust gets into the bathroom. Probably someone has mounted a fan on the grille and is blowing his air into you. If the air is really backing up, call a chimney sweep immediately – this situation is life threatening. The grille remains as it is and the one in the door is not to be covered, otherwise you will suffocate from the carbon monoxide (carbon monoxide) from the furnace. The circulation should be such that the air enters the bathroom through the grille in the door and exits through the grille to the chimney.

It seems that I was mistaken, because when the candle is placed against the grate, the flame deviates towards the grate. So in that case, that cold air must be coming out of the apartment through the grilles in the doors. I understand that the only solution is to close windows :/
What about that dust? Is it really coming from the chimney? There was a lot of dust on the grate and behind it in the chimney, so I thought that's where the dust was coming from. Same in the kitchen. But it turned out that the air does not come from the chimney, so I don't know anymore.

In the kitchen I have a not very aesthetic grate, so I wanted to buy one with a strainer and by the way I would also buy one for the bathroom. If it's dust coming from the chimney, the sieve could stop it, by the way, I wouldn't have to worry about any insects flying up the chimney. So can I install one? Air circulation through this strainer will not suffer?

And is the dust evenly distributed throughout the room or closer to the chimney? Put something under the grate and see if something is really falling from the chimney. I think it's probably dust on the ceiling I don't know if this grille is removable so that it can be reinstalled because they are like that. If the grille can be removed easily, take a vacuum cleaner and thoroughly vacuum everything behind the grille as much as possible

Rather, the entire bathroom is evenly dusty. Well, maybe it gathers the fastest in the bathtub, but that's probably because of the washing. i.e. when he moves the strings or collects the laundry, he flies to the bathtub.
The grille is removable, I also vacuumed the inside.
The ceiling is suspended. It is possible that it is dusty, because when I cleaned the tiles, the cloths were black. In some places I did not finish cleaning, as well as the ceiling.

What about those grilles with strainers? Can I install it without any worries?

I believe that we are dealing here with the so-called secondary sequence. It arises depending on the difference between indoor and outdoor temperatures, humidity, wind and stuff. You probably have a gas boiler creating negative pressure. If you have airtight windows, doors and a styrofoam facade, just use window vents and put a "fireman" on the chimney, it should be enough. Good luck

Suspended ceiling in the bathroom My opinion is a misunderstanding to have a suspended ceiling in the bathroom where there is a pile of damp dark and warm This is an ideal environment for the development of everything possible You probably already have mold or fungus there Better take off some boards and take a good look at it because it's probably mold coming from the ceiling

My colleague has a point.
This happens in buildings with a short chimney, and on the upper floors.
The fact that the candle just leaned out does not mean that it is always like this, on the contrary, most of the ventilation takes place in the opposite direction.
As for the dust, due to significant humidity, dust particles are bound and stuck together, they form such specific tomcats and settle mainly on the ventilation grille and more.

It should also be remembered that when the flush is used frequently, water around +5 degrees can well "air-condition" the bathroom, which should be taken into account in heating.

The use of an extractor fan will probably cause air to enter the kitchen grate or hood.
Most of the problems are caused by too tight windows, which have become fashionable.
Grilles and nets will only improve visually.
You can't close the ventilation with awnings etc because there is a gas junker in the bathroom.

The windows are plastic, sealed, but always open. Even in winter in one room or kitchen is ajar.
The doors, however, are leaky.
I will rather give up the fan, but the grilles with meshes must be installed anyway, because as I wrote earlier, the ones I have are unsightly.
My bathroom door is often open. It is good or bad?
What am I supposed to do now? Should I call a chimney sweep?
Are diffusers necessary? Because it probably costs about PLN 50 for one window... And I don't really understand this 'firefighter'. I don't live in my own house, but in an apartment block.

A fan is always useful, if only to remove moisture and water vapor during the bath.
Mount this fireman.
Door or open, it doesn't matter.

1. Could you explain what this fireman is about? Because I don't know much about it. I thought it was mounted on the roof, on the chimney. And I live in an apartment, so how do I install it?
2. So how about this fan? Because you wrote earlier that the use of a fan will cause air to flow through the grate in the kitchen. Unless you also install it in the kitchen?
3. And if I were to buy a fan for the bathroom, which one would it matter? It can be cheaper, up to PLN 50, or rather something specific? With a moisture sensor or something?
4. Regarding the suspended ceiling, unfortunately, I am not able to remove individual panels. But in the hall, where the gas meter has a hole, I looked through it and there is no mold so far. Maybe put some moisture absorbers in there? Also to the bathroom. There are such products from Humistop or Primacol and apparently they do something.

It is a pipe with a swivel end that adjusts with the wind.
Ask the administration to install it - this is your ventilation duct, but I don't know how it relates to gas regulations.
Match the fan to the hole, there are 100; 125 and various powers, I smoke and have a strong one with a timer.
