Philips PureProtect Mini 900 Series HEPA NanoProtect Filter FY0910/30

Very happy with it, a breath of fresh air, literally. Works properly and cleans the air well. Installation is quick and easy, and replacing or cleaning the filter is very easy compared to other air purifiers I know. You do notice that the filter needs to be vacuumed a bit more often than the device indicates. I have two birds that spread quite a bit of dust, and you can see that quickly on the filter (which clearly shows that the purifier is doing its job well).

I have the impression that the air is being purified. The device immediately detects impure air.

It works well
