Being highly allergic, and not wanting to spend hundreds of euros for a smart filter, I decided print one.
Or at least the thing surrounding the filter...

The filter I used is the Xiaomi Smart Air Purifier 4 Compact Filter which I think is perfect as it cost no more than 30$, and blocks basically everything.

As smart module i went for the Sonoff Basic, which is a 220v remote switch compatible with Google/Alexa.

A fan is needed (no air is gonna move otherwise). I choose one from AliExpress which is maybe a little too powerfull (and noisy) | High Air Volume Fan 120mm (Type C). It has the following specs: 4600RPM / 160CFM / 12V / 1.34A.
Again, probably overkill for a small home filter, so choose whatever 120mm fan you like

To connect the switch to the fan i choose the Adogo transformer 60w, 12v, 5A. There are many other with the same dimensions/specs on both amazon and aliexpress.

Below time and material to print each piece

• Base ~11h 109g
• Side ~ 2h 20g
• Top ~11h 106g
• Fan&Power ~14h 145g
• Cover ~ 8h 67g

Inside the Fan&Power and Cover, I have designed holders for the electronic components. I'm including also the 3mf files so you can remove/edit those in case you decide to go for other switch/transformers.
