does use of AC improve indoor air quality ?

Recommended Posts

I read that a very important factor of air quality in Bangkok are the numbers of dust particles in the air.

Does use of air conditioning improve indoor air quality....I do not see dust particles coming out of my AC...

Of course you cannot see dust particles coming out of your AC. They are just too small. And this is what makes them dangerous.

 

Anyway your AC does only filter out the dangerous particles if it has this functionality. An ordinary AC does not filter out PM 2.5 dust particles.

 

In our bedroom we have a Samsung air-conditioner which filters out PM 2.5 dust particles.

 

In the other rooms we have the Hatari purifiers. They are the cheapest yet most effective. We check with a digital meter for PM 2.5 dust particles to make sure.

We have a Panasonic with nanoe G technology. If you accept the claims on their website, it does indeed remove 99% of these pesky little particles that we're all getting so excited about.

 

I can't, with all honesty vouch for their claims because we live in a region with fairly good air quality anyway, but I've no complaints about the unit thus far. You might find this website informative.

No, it makes it worse by concentrating the pollutants in a confined space (the room).

Not as such, BUT if you can close off all windows and doors so that zero outside air enters, and you have a clean room to begin with via say some form of HEPA unit, and you put your system on internal recirculate, all would assist. Remembering these particles are apparently around 3% the dia of a human hair and tend to stay suspended in air for long periods.

If one could set up a stack of sprinklers in the bedroom and give it all a good wash down before bed, then this would have to be an advantage.

Check out the news from Melbourne where the remnants of a dust storm from South Aus descended, and was washed into every crevice of Melbourne via torrential downpours.

Only if filtered. My 3M filters turn disgusting dark gray in a few weeks.

Which Hatari model and how much? Also where did you buy it from?

Bought this 3M filtrete at Homepro and installed on the a/c units in living room and bedroom.  One package 15X48 cm covered all 4 filter panels (2 per a/c unit).  Says it filters out 2.5, have no 2.5 meter, so cannot check, but I feel better ever since installing a few weeks ago

It may not filter out the small deadly particles but you'll feel a hell of a lot more comfortable as you slowly die.

When I switch on the aircon it makes no difference to the PM 2.5 levels. I use a cheap air purifier I got from lazada. It is rated for up to 32sq meters and my room is 35, so it takes 2 hours to bring down the PM 2.5 to reasonable levels. This one:

this has been my experience also.  got an air purifier from lazada a few weeks ago.  having the AC on doesn't seem to improve the PM2.5 levels, nor does it make them worse.  opening the sliding door for an hour tends to double the PM 2.5 level.  as long as i keep the sliding door closed, the PM 2.5 levels stay relatively steady.  they don't increase overnight.  so i only need the purifier when i've let 'fresh' air in.

The aircon will have 2 positive effects. It will clean the air because a lot of things flying around will be removed at the evaporator with the condense water - some have even HEPA filters. The other positive effect will be that you don't smell so much in dry air. In respect of air cleaners you have to be careful especially if it comes to Ions. Normally they are created by a light bow with very high voltage. But not the voltage is the problem (you can touch the area) but the ozone that is created.
