lol That's exactly what I asked myself after buying a new filter! So plastic really is (unfortunately) household waste. But it has a metallic net. On the net I only find recommendations for household waste unless it's a large amount. That's all I could find.

Hi, I had a look on the internet out of my own interest. Apparently the dimensions are very similar. This filter has Height: 29.3 cm Width: 20 cm Your original filter for the Air Purifier 4 has Height: 29.3 cm Width: 21 cm It is best to order the M16R-FLP-GL. You are guaranteed that it will fit. LG. Michi

yes

It is a composite filter with activated carbon.

The inner diameter is exactly 14.8 cm. Greetings Rolf

The Mi Air Purifier HEPA Filter does not fit the Xiaomi Smart Air Purifier 4. The Xiaomi Smart Air Purifier 4 uses a specific filter designed for this model and is not compatible with the Mi Air Purifier HEPA Filter. The matching filter for the Xiaomi Smart Air Purifier 4 is the Xiaomi Smart Air Purifier 4 Filter.

No

In the house, quite normal. Unfortunately needs a lot of space 🥲

This filter is compatible with the following devices: Xiaomi Mi Air Purifier 3H, Mi Air Purifier 3C, Mi Air Purifier Pro, Mi Air Purifier 2H, Mi Air Purifier 2C and Mi Air Purifier 2S Unfortunately, it does not seem to be compatible with your air purifier 🙁

I have the same combination, it fits

Original filter replaced

I don't think so, because the Xiaomi Smart Air Purifier 4 Pro filter has different dimensions, see here: Xiaomi Smart Air Purifier 4 Pro Filter

Yes, I bought it myself for a 3C.

Sorry, I don’t know.

According to the manufacturer, it is compatible with the following models: Mi Air Purifier 3C/Mi Air Purifier 3H/Mi Air Purifier Pro.

Yes, it's compatible with 3C/3H devices. I use it for both devices.

No, only the green one can do that.

Yes, it works and has the NFC chip.

I think so

Xorondra's 03.09.2021 "According to the description, violet has an antibacterial effect, the green filter absorbs formaldehyde, which is a solvent used in paints and treated wood panels and is released into the indoor air over time. This filter would be recommended for new buildings and after renovations, for example. The grey HEPA filter is the standard dust filter." I hope I was able to help you with this xD

Yes, I think so, it's the same model.

The Best put it in a Waste Bag and put a Stamp; it is going to the Incineration Plant in Switzerland. NO recycling is done ; there are only COLLECTING and EXPORTING the Household and Industrial- Waste. Most of the used Clothing, Electronic waste , waste Batteries, Tires, Plastics (mostly) are EXPORTED. These regimes export all THEIR Waste to poor countries in Europe (Eastern Europe), Africa or America or even Asia. The Waste management in Europe (and elsewhere) is mostly criminal and subventions from some Rich Governments to their EXPORT Waste to poor Countries !

Hi I do NOT know the model H3 ? However I use it for the model I bougth = Ref. Xiaomi MI Air Purifier Pro H (60m²), delivered in February 2021 by GALAXUS.

According to research, this filter is designed for the XIAOMI MI Air Purifier 2 and Air Purifier 2S.
