I need a really good one and don't mind spending decent money on it but some are very expensive and it would be sad if it was crap!
HEPA, not too noisy, able to deal quickly and effectively with smoke/brewery stench/pollen/allergens, no microphones wifi connectivity nonsense, no ion/ozone emission, preferably with auto air sense and air quality monitor, and we are a bit pushed for space.
Any ideas?
