If to be on the safer side its better to get an air purifier what kind of technology works best, assuming there are many. My budget would be 20-25k unless something in 30-35k is like state of the art stuff.

EDIT: This looked like a decent product with the amount of features it has but I'm totally unaware of what all to look for in air purifiers.

While you can purify the air in her cabin, every time she opens the door the air will be fouled. In such cases you need an air lock (two doors separated by a short passage) so that the outside air does not have direct access to the room.

In short you have to tackle the air quality in her room as a project
. Airlock for entry
. Air filters - both primary and secondary for bringing outside air to the cabin
. Split AC for the cabin (as the window type will bleed dust into the room)
. Air purifier for cleaning the air in the room.

A stand alone air purifier will have very little effect and will soon be choked if the traffic to and from the room is moderate to heavy.

The primary use is for parents bedroom (14*16 feet) and I hope this helps my asthmatic mom.

Hi Sanjay

does a domestic air filter help clean the air ? My mom is a severe asthma patient and I was thinking of getting one.

I wanted to understand if there's a way to check the air quality before I decide to buy her one of the air purifiers.

I recently bought 2 purifiers, Panasonic F-PXL45A Air Purifier which has a Hepa Filter as well Neo technology. It does have different lights to show the quality of Air as well LCD display in case PPM is high. This cost Rs 21,000.

The second one probably one of best worldwide - IQAir Health Pro 250, during Demo/installation, Panasonic purifier was able to bring 350000 down to 30000 or so maximum but IQ Air within 30 minutes bought levels to less than 1000 Panasonic output side measured at purifier was never less than 2000 whereas IQAir output is Zero. If money is not a concern then should go with IQAir. This model retails around Rs 90,000.

Airlock is out of the question but we do have a split AC installed. In a day I'd say the door would open/close about 30 times at least.

I hear what you're saying, but wouldn't it still better the air quality to a significant extent even if the door opens/closes every 15-20 minutes?

Yes Air Purifier will help, but with so many opening/closing cycles you will be straining the air purifier and the filters will need to be replaced in extremely short time if there is a lot of dust/lint in the air. Your situation is similar to having clean air in a room situation inside a coal mine - most challenging.

The Air purifier is a short term solution, while an airlock is a long term one. Depending on the cost of filters you will recover the cost of constructing an air lock in as little as six months.

The product that I saw didn't need the filter to be replaced, only dusted. Its 2 filters have 10 year warranty each.

Filters that can be cleaned are generally large aperture mesh filters and are of no use for fine particulate matter. Filters that can intercept fine particles are made of special fibre filter material and cannot be cleaned, hence have to be replaced.

An apt comparison is the older type mesh air filters in cars that needed periodic cleaning and modern air filters that need periodic replacement.

Some companies lose you in technical mumbo-jumbo in order to impress you. This looks like one to me. The "nanoe" they are talking about seem some chemical process of breaking down viruses, etc.

For your application I would recommend a standard non-mumbo-jumbo air purifier which has a pre-filter and a HEPA filter. By the way, HEPA filters are used in filtering air supplied to operation theatres.

Wouldn't an air curtain occupy lesser space? The kind that sits on top of the door and blows a stream of air downwards, as seen in malls.

On air filters: I was not aware of this category of products until a few months ago. Now I see this is the most active category of appliances being discussed.

I am curious: What is the driving factor for this in 2016?

Which model did you get, NoMind? Is Aeroguard part of Eureka Forbes? Thanks.

Guys, any feedback on good ceiling fans to go for? This is in Chennai. I need to replace a whole bunch of them at my folks.

Please do let me know. Tons of brands available online.
