hi all, im in search of air purifier that works well in improving air quality
have pets in home and 1 kid that allergic to dust hence in some day he will sneeze non stop
does different of hepa filter has different function?

Get ionizer.

air purifier with ionizer? how does it different from common air purifier?
btw read across that there is air purifier that able to destroy formaldehyde
what does it mean? would like to hear opinion on it too

HEPA comes with a standard, however so long your filter met with the minimum requirement, you can call the filter HEPA. So most good filters actually have standards better than HEPA to filter smaller dust particles and even virus.

Since your kid is allergic, suggest you go to
https://www.allergyuk.org/get-help/products...ifiers#products

click on the filter to see what are the products recommended able to filter off the allergens you're facing

So far I think the only one that can get rid of everything is Amway Atmosphere Sky

Am using one, and I can attest to its performance.

PM if you wanna know more

Ionizer uses an electrical charge to remove dust particles, but cannot filter gas and odor.

Mechanical filter still better in being all rounded.

Also after dust particles are ionized, they are not being trapped at the filter, hence will feel that floors are dustier.

thank you for sharing your experience
when I ask ppl around, quite few of them using dyson air purifier and said able to capture virus and pollutants
any feedback about it? able to destroy influenza and formaldehyde which sounds alright to me
of course im open to any suggestion and feedback...would like to compare before decide which to get

You need to buy few units to place in different places.

Other than air purifier, you need to get rid of carpets, avoid fabric sofas, wash curtains, bed sheets, pillows and air cond filters frequently,

if want to test, can get mi air purifier as it is quite cheap for few hundreds RM

difference of their model is the coverage area

Set your spending range then we can give suggestion what you can look at it. Otherwise, if u just concern about dust, currently in market there are rm300 - rm800 airpurifer with hepa filter can work well too.

thanks for the tips shared and been constantly changing, cleaning it
no carpets in house, been eyeing on some brand
currently planning to get one and see how effective it is before buying more to place in few spots

that's sound alright for cost efficiency,,,are u using it too?
what do u think about dyson? don't mind to spend more if it is a good product
they pop oout whn i search for air purifier...seems like they have new model release

noted with your suggestion...not setting a budget but if it is a product worth to buy, not mind at all
since kid always sneeze, will be great if the purifier can reduce airborne virus or pollutants
different hepa filter has different function?

Myself suffering from sinus since i was kid, yet my current air purifier do help me solve this problem after one month i use it.... and until now already around 2 years, no more sinus in the morning like those days.........

According to WHO, only hepa filter able to filter viruses.........

Usually, in the market.... most HEPA filter are with 0.3 micron filtration.
But..... viruses are usually 0.1 micron or smaller than that.... so common air purifier with 0.3 micron dont really can filter viruses.

Would recommend you can try the air purifier i use currently, it's HEPA+, which is 125x better than HEPA.

am using Coway Lombok 2, can notice the fur of dog blocked at filter side, no issue on its fur so cant tell whether got any difference.

u mean TP09? looks good and able to filter formaldehyde, can wait for more reviews if wan more confirm
if budget and maintenance fee is not a problem just go ahead

additional info for filtering virus via air purifier
https://www.vaniman.com/do-hepa-air-purifie...covid-19-virus/

thank you for sharing ur experience...yeah virus usually smaller
that's also reason why im eyeing on dyson new air purifier since it can filter ultra fine dust, pollutant as small as 0.1
if want to get one, don't mind to get a more expensive one so can use at ease

yeah the new tp09...whn ask some of my fren, not many actually aware of formaldehyde
believe what u pay what u get, so thought to get a better model so can solve all issue which is why tp09 is one of my choice
ohh ya many would actually diy with the filter

atmosphere sky able to filter down to 0.0024 micron, Formaldehyde is in the list of contaminants as well, and black and white listed all 327 airborne contaminants.

you can refer this website, for all certified air purifier that can filter formaldehyde, actually only 5
