Home air purifiers effective for improving indoor air quality?

Air purifier filter in just 15 days.

How much of our lives are we throwing it away by merely breathing in an Indian city?
This is what we can see that prefilter catches. Pm 2.5 we cant even see easily. So if PM 10 is low and PM2.5 is high then air might look ok but is still bad.
My asthma and allergy symptoms are much better after using AP + regular Vaccum cleaning + regularly wash bed stuff and curtains.
But there is still exposure when i get out and also in air pockets around windows where air is leaking in.

Every city i have been outside India (Canada/US/Israel) has had very clean air and i never had any respiratory issues at all. In India its reverse ..
Also Indian houses don't have hvac type stuff generally, perhaps because temperatures are moderate ( but it can be so cold in winter in north).

Which city are you in? What model purifier? In the Living Room or Bedroom?
Pune.
Xiaomi 4 lite.
Kitchen.

Very true. There's no visual cue for PM2.5 pollution. It perhaps gives a uniform bluish tint (from the sky) to very distant dark shadows on a nice sunny day.

Pune, on most days, has higher PM10 pollution than PM2.5. And, that's what we see on the prefilter.

Do the air purifiers remove second hand bidi/cigarette smoke? Some downstairs neighbour of mine is a chain smoker and if i keep the windows open, all the second hand smoke comes in my home. I just can't stand the smell and have to close the windows immediately. The smell takes long time to go away. Can these air purifiers help in such case?

I doubt any Air Purifier works if you keep Windows/Ventilations/Door etc. Open, as they are meant to work in close door environment, check before you buy.
 
yes, and you will need carbon(gas) filters for smoke (cig/fire). And carbon filters that come with AP usually get used up within a couple of months from what i read.
So maybe something that has much more activated carbon would be better if available.

Just google and see how to filter smoke
