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).
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.

Bought this in Amazon during July 2023. Mainly got it for it's ability to remove the pungent burning smoke smell and other bad odours. I felt that it cleaned the air effectively for 100 square feet in a closed room. I replaced the filter once after 4300hrs as the filter replacement light lit up. The cost of the filter is Rs.1200/-.
Highly recommend this one: Philips AC4221 Smart Air Purifier https://amzn.in/d/2tmQ2PB
It has a CADR of 600 m^3/hr which if you put in a bedroom does wonders to clear the air rapidly and silently. Rated for 99.97% purification of 0.003 micron particles.

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 picked up two of these for my and my parents' room. They have done wonders. I wake up with open nostrils, and allergy-related sneezing/coughing has disappeared.
I plan to pick up the regular 4 (non-lite) for the living room.

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

The non-lite version comes with a negative ionizer. In theory, it's great to eradicate mold or that stuffy smell you get from mattress and wardrobe clothes. So you may want to put a non-lite version in the bedroom too.
You are right. But I think it's still better to have an air purifier even with the windows open, rather than no purifier at all.

My room PM2.5 count goes up quickly when windows are open. Depends on cross ventilation/wind too and how much window is open.
Probably if AP is beside you and between you and window, it might help a bit.
I keep AP running 24x7, it hardly uses any power anyway. But i only open windows when needed else it defeats the purpose.
To get outside clean air, we will need filtered intake.
Tulsi plant will be in balcony. What will I do inside the house where there is no sunlight? That guy smokes continuously from 6am till 12am at midnight. I think even plants will die trying to clean the air in my hall. I smell like a smoker even without smoking.

buy pedestal fan, face it toward balcony from where smoke coming in, keep it on and it will partially stop major part of smoke to enter in hall. Out of 4-5 windows panel, just keep open one slide only thus tobacco smoke will not enter in hall from other open slides.Tulsi plant will be in balcony.

if have good/fresh air from kitchen window or bedroom window, install 'outside in' heavy duty exhaust fan and let the fan suck all out side good air inside and pedestal fan in hall will throw that air out of hall.
If already have exhaust fan in kitchen to throw inside air out, add one more fan to bring outside air in and make sure not to use both at same time.
