I live in a studio apartment with a 3.3m ceiling and was wondering if the upper air pocket would mix better with vertical outflow?

The 3200 has horizontal airflow, and I'm not sure if that would work well?

Has anyone tested the differences in rooms with higher ceilings?

Basic info:

- Country: Belgium, EU

- Bedroom: 4 x 3.5 x 3.3

- Living room: 5 x 4 x 3.3

- Filtration: pollen, dust, odors (mold?)

- Budget: 270eur for air purifier, 70eur per filter, 53 Watt on highest speed, 15 Watt on highest speed below 45dB

Extra info:

- Pets: 2 shorthair cats, 1 shorthaired dog

- Current devices: Winix Zero S and Philips 900

- Insulation: no door between the 2 rooms. Bad insulation, windows and the door have gaps

- Pollution: quite a lot of cars and a busy bus stop + big park nearby

- Ventilation: my bedroom especially gets very musty when I close the windows, so I prefer them open (and so do the cats), but close them when my allergies act up.

- Noise: I prefer to run purifiers at below 45dB for sound comfort, especially in the evening and at night.

Does anyone have any experience with both? I currently have the Winix Zero S for the living room and a Philips 900 for the bedroom. I like keeping windows open whenever possible for fresh air because my bedroom gets musty . I live in a medium-polluted city in Belgium and have 2 cats and a dog. I'm allergic to dust (mites), pollen and more.

I'm not satisfied with the Philips 900 and would like to replace it, but was wondering how often I would have to replace the filters. When counting costs, 2 filters per year would make Philips 3200 more expensive.

For 6 air changes per hour for my bedroom, I need at least 140CFM. 12x3.3m²

Winix Zero S basically has higher electricity costs, but very cheap and accessible 3rd party filters priced from 21eur and upwards with tons of carbon (too much??)

Philips 3200 is quieter, a lot more efficient (169CFM vs 134CFM) at -45dB, has allergy sleep mode, no ionizer, adjustable lights and a better app.
