no aircon is to make cold air only     the rest depend on other

everytime i on projector, knn i can see tons of dust flying all over my room

i think i get xiaomi and cheap filter from tb and cause if shoppe expensive by how much (if less then $10diff i just in sg)

Daikin Streamer Air Purifier i think the 10yr is up to 10yr, i try search for answer, where does the dust go, cannot magically MIA. it say need to vacuum every 2 week (who on earth too free to do that 2 times per month) to remove surface dust from hepa (deep inside i believe vacuum also cant reach) .so i believe once the dust from the hepa is full, need to replace liao, that 10yr so likely is up to 10yr, might be 3 or 5yr if home lot of dust   how to reuse if cannot use water to clean the dust. the dust is trap inside the fiber i dont see any tech can solved it unless they have new tech dont use fiber to trap dust as such just get xiaomi better, every 6 month or when needed just replace filter
