There are many ways for people to beat the haze but the best is to stay indoors with the air-con on and all doors & windows closed as tightly as possible. OK fine, I just want to know the cheapest & fastest way to purify my air!
I recommend using the air-con as your MAIN air purifier for 2 simple reasons. It’s the most efficient and fastest mover of air in the house, and it’s also very quiet (typically 25dB on Auto). BUT, obviously the filters in your air-con are not actually very good. Some air-cons have UV and Plasma technology. UV kills virus & bacteria so it only sterilize the air, not filter dust.
SO, the best solution is to introduce another filter behind your air-con filter.
I recommend the 3M Filtrete Room Air Cleaning Filter with Carbon. http://solutions.3m.com.sg/wps/portal/3M/en_SG/Air_Water_Filtration/Filtrete/Products/Air/?PC_7_RJH9U52308OF00IUFJUDQU1025000000_nid=XK72KFCZWDbeR5DTNSR8KWgl
It’s an electrically-charged membrane filter with carbon so it’s able to filter particle down to 0.3 micron + the carbon will help to absorb harmful chemicals & odour. It’s not as efficient as a HEPA filter but because the air-con is pushing so much more air through the filter per minute, the result is still very good with noticeably cleaner & neutral smelling air in 10 minutes.
It’s recommended to cover up to 70% of the air-con filter to allow good air-flow so the air-con cooling power is not compromised. Each box contains 2 pieces of 60 x 30cm filter, which is enough to last an air-con blower unit 18 months if you change it every 2 months. For less than $30 per air-con unit per year, I’d say that’s VERY cheap!
Lastly, for you people who are lazy, you can install the 3M filter OVER the air-con filter so you don’t even need to wash the filter in future.
