I know my posts will pop up hours late as it will be approved by mods and then posted and a new post also will end up somewhere in second page of New Posts .

but still nobody has used any ionizers in their cars?

[knp]

^^ I am using the same one bought from DealExtreme.
I don't really see any difference and don't think that these things really work!

[1self]

The ones which finetuning talked about are for 725$ on the net! So obviously these cheap ones will not work. I have had a similar one for a year now...do not see any difference.

Here is my car air purifier.I purchased it from a Mumbai dealer costing Rs 2500/-.Its manufactured by Crompton Greaves.Very effective removing bad odour and during long journey with ac on consistantly.I hardly feel to roll down window for fresh air during long journey.

[1self]

finetuning, where in mumbai can i buy this? I really do want one?

[Prowler]

You can also buy cheap Chinese made Negative ion generators from electronics shop. I saw one such unit selling for rs.550/- in Richie street in Madras.

I have used similar one. ($6 from US)
It worked for almost a year, then stopped working.
I could feel some difference while using it.
The dust settles down fast.


Some of the domestic Air Conditioners are having ionic air purifiers in-built to it. The manufacturers claim that it delivers fresh air.
Anybody thought of using the same concept integrated with the car AC?
Or is there any such thing already available?

So i was window shopping for car air purifiers as i stay in Delhi NCR and came across HEPA cabin filters by bosch. However there is no information on their sizing etc on the website. Why are more manufacturers not offering such filters for Indian cars? These will be much cheaper and better than having another device in car as the car AC anyway recirculates air with a dust filter but adding a hepa filter will make them a good option to get cleaner air free for PM particles.

HEPA filters, the originals have to meet certain specifications and they are used in vacuum cleaners to biomedical equipment (been seeing them from childhood since my mom runs a lab) .

When it comes to cars,

1. Some cars come factory fitted with HEPA-looking cabin filters.
2. Some have a slot for it but does not come with it installed. ( yep)
3. Some come factory fitted with HEPA-looking filter and the aftersales guys may replace it with something cheaper that is washable :(
4. Some cars come with washable filters, you cannot use HEPA here, as HEPA needs more space.
5. Very rarely do cars come with filters with HEPA standards.

As per Bosch website it meets a certain standard which has nothing to do with HEPA/MERV and it is a standard that is no longer in practice.

HEPA being an abbreviation can be used by air filter manufacturers to mislead you, Bosch included.

So what should you do? Use a manufacturer recommended Purolator filter, works well and keeps your AC in good health.

If you want HEPA in car, buy a portable air purifier with a proper HEPA filter.

Hope this helps.

I've been using this Bosch HEPA cabin air filter -- bought from the US -- in my Civic for over 2 years now, and it works great. The filter is supposed to fit the Civic. Today, I decided to change it to another piece of the same brand and I was running without a filter for half a day. The difference was noticeable and I can still smell exhaust fumes in my breath.

I don't understand the argument you are making. Car air purifiers have HEPA filters within them. So, what's the difference if you put in a HEPA filter as your cabin air filter?

Sure, happy to help!

HEPA is a loose term and the test protocol which Bosch mentions is defunct , it is just marketing as I see it. But if your observation is different and it works for you, I think you should go for it.

Interesting. But it's still better than a filter that is not HEPA rated, isn't it?

Are the protocols for the air purifiers any better? And, what's the details of the protocols one needs to look for which is the most stringent? Thanks.
