4000i Series Air Purifier AC3858/50R1

That’s much too small for 60sqm. I think 4000 Series with 500-600 CADR is fine. This one you can run on speed 1 and it cleans your Appartement. The small ones are ok when you are not there because of the noise.

I use the 4000 series for 30-50sqm rooms.

Yes, I mean Philips. I can't give u informations for the shown device. Be aware that it can get very loud when the device is too small, especially when it´s in your bedroom!

The filters on the 3000i and 4000i are the same FY4440/30. I have the 4000i among other Philips and I recommend it, although keep in mind its measurements since it is a fairly large device. At what price have you seen it?

I have 3 philips 4000i 1 philips 4200 and a coway airmega 50.

We have 2 Philips 3000 series. Filters last about 3 years ( really). Ideal for big rooms and allergies like mine. Unfortunately they stopped producing these. The next gen are smaller but also with 1 year filters.
