Air treatment

Does anyone know what the difference is between the different HEPA filters from Xiaomi? They don't all cost the same and all have a different colour. https://www.digitec.ch/de...

Hello. I'm looking for a dehumidifier that can be connected for continuous water output AND a thaw function. The reason is simple: I currently have an appliance whose tank I have to empty very regularly, and whose plate regularly freezes, leading not only to inefficiency but also to a nice puddle of water under the appliance. Despite the 522 products on offer, it's hard to find what I'm looking for. For continuous output, it's pretty clear. The problem is the thaw function... several appliances have this function, but when you look at the instructions, you find for example (Albert Little appliance): "Thaw function: If the room temperature is below 5°C, the dehumidifier will automatically operate in defrost mode". Great: either the description is a load of rubbish, or the function is useless: it doesn't often get below 5°C in the laundry room... Others say 10°C (same problem). Finally, I found the Blaupunkt ADH601 model. But it seems to be the only one in the range of 522 products (and here, the description is, with a home-made translation: the instructions have 14 languages, but not French...): "When the internal temperature of the cold plate reaches a temperature close to 0°C, the appliance automatically starts the defrost mode". Hallelujah! But the choice is limited to 1 appliance... Have other internet users bought or found other models that have the 2 functions requested?

Hello, Due to a weakening of my immune system, I currently need to protect myself against viruses, and I would also like to do something about my mite allergy (I also have a pollen allergy in spring). I am therefore looking for an air filter for my practice room (approx. 15m2) and possibly also for my bedroom or office at home (also approx. 15m2 in each case). Which device is particularly good against viruses and mites/pollen? I look forward to tips!

Hello everyone I am looking for one or more air filters against pollen. The situation: I have 2 rooms (bedroom and office) of approx. 20m2 each and my workplace is more than 100m2 and there is movement in the air. I have looked at the following articles: https://www.galaxus.ch/de/s2/product/xiaomi-smart-air-purifier-4-compact-27-m-luftreiniger-22862906 https://www.galaxus.ch/de/s2/product/xiaomi-smart-air-purifier-4-48-m-luftreiniger-19112333 https://www.galaxus.ch/de/s2/product/ible-airvida-m1-luftreiniger-15234078 What do you think, would the Compact be sufficient in the 2 rooms and is the Airvida something for my workplace? Unfortunately you can find quite a lot of good and bad things about all the articles.

I'm looking for a fairly fast dehumidifier for my office/bedroom (around 20 litres/24 hours). It should be at least reasonably economical and quiet. It would be nice if it also had something like a hepa filter and if it also switched off automatically overnight (with its own timer or alternatively via an external timer or app, it doesn't matter) Is there such a dehumidifier? My previous fan was the Stadler Form Albert, which dehumidifies quickly and has a built-in timer, but it gets dirty inside very quickly and it keeps restarting, even when the humidity is already much lower than set

I only want to run the dehumidifier with excess solar power and therefore plan to connect it to my home automation system. How can I see if a device starts automatically as soon as it is supplied with power? Is that standard?
