I have a Honeywell HAP-16200E in the bedroom which should be good for 20 square meters
At the highest setting, it emits a noise of 53 decibels. The lowest setting is still 45 dB.
I call that terrifying noise. My computer is quieter than that. The thing is off when I go to sleep.
The effect on health has not yet been sufficiently proven except for people with asthma/allergic reactions. It also delivers a great deal of particulate matter whether you live in the middle of the city center or in a small village in Friesland. Also get rid of your gas stove because it produces a lot of particulate matter. Or if this is not possible, at least set the extraction system to maximum and open the window (or ventilation grilles if any) see TNO research (2)
HEPA (High Efficiency Particulate Adsorption) filters can stop virus particles. from SARS‑CoV‑2. Particle size 0.06-0.14 m. A HEPA filter should stop 99.97% of particles between 0.15 to 0.2 µm. The efficiency is greater for larger and smaller particles. For an explanation see (1)
For best results, the machine should run 24 hours and replace the HEPA filter on time. Also make sure there is sufficient air flow (ventilation). The thing also has an ionizer but it produces toxic ozone. The maximum is 0.10 ppm. ARB certified devices are allowed to emit 0.05 ppm of ozone. But a large study concluded that even a dose of 10 PPB (parts per billion) actually has a measurable adverse effect on health. So I will not use this feature.
It is also best not to eat strawberries from the supermarket (3).
