I saw this philips go-pure portable purifier..can use for both car and small rooms (I believe referring to bedrooms) but rather pricey at 299. Also not sure good or not.

I understand purifier dun work well unless its enclosed area..in tat case living room not very suitable?

Thinking of buying a air purifier in this hazy environment? Get a True HEPA Filter (if stocks still available)

True HEPA aka High Efficiency Particulate Arrestance filtration technology is regarded as the best form of air filtration in the industry.

To qualify it must remove 99.97% of all airborne particles as small as 0.3 micrometers (microns) in diameter.

A particle that is 10 microns or less in size is not visible to the naked human eye.

Airborne particles include pollen, allergens, mold spores, dust mites, viruses, germs, pet dander, cigarette smoke and odors.

True HEPA filter is exclusively used in medical, laboratory and commercial applications where totally clean air environments are required.

Check the specifications before buying.

** Take note there's a difference between HEPA and True HEPA.

EN1822 standards, use the second column as a guide for the filtration %, normally your filter specs will state things like E10

For car, just a cairefresh hepa aircon filter will do. But house is a different matter.

I've read quite a bit over the last 2-3 days on these. i posted my conclusions on FB to my friend earlier so i will repost it here.

This is comparing sharp plasmacluster vs honeywell 17000 (from amazon).
Yes u need a true HEPA filter to effectively get rid of the small particulate matter.

pros and cons to both of these units. I've done my due dilligence. So i'll summarise my findings.
Pros & cons:
1. Technology other than the HEPA filter: Sharp uses ioniser which attaches both +/- ions. Apparently the act of attaching - ions alone creates ozone. And the - ions floating around may be bad for allergy sufferers? Sharp claims that creating both ions negates that effect. And also the ozone produced is negligible.
Honeywell simply uses activated charcoal pre-filters to adsorb larger particles
2. HEPA filters can generally last 1-3 yrs depending on usage. I don't know whether it's easier to find honeywell vs sharp hepa filters. Low end models they don't tend to support well. Problem with honeywell is that the manufacturing of their replacement stuff is sub-coned out. There's varying quality according to the americans on the quality of these filters. Some manufacturers claim it's washable. I highly doubt so.
3. Pre filtration. Very important so that the HEPA filter has good longevity. Honeywell uses activated charcoal, 3 months. Cannot be washed/clean. Some manufacturers claim to have washable carbon filter. Lol i dunno how true is that...
http://wiki.answers....aned_and_reused
The HEPA filter itself is passive. however, it's shelf life depends on pre-filtration of large particles which can clog it. Hence the importance of pre-filtration.
4. Noise. Sharp and other manufacuters have a quieter fan. Honeywell is typical american product. primitive and more noisy. However, bear in mind that the HEPA filter is passive and that the fan has to draw the air through the filter. Stronger fan = more noise is inevitable. Quiet fan may mean that the filter is working but very very slowly...
5. Warranty issues - buy from usa can forget about it. Also need a stepup transformer costing about 20+ dollars (can buy from challenger).

Anyway i bought a honeywell cos' of these issues affecting longevity of the air purifier. But frankly, all these cheap air purifiers have pros and cons...

hi,
could the writer point out which sharp model is the comparison made against ? its like comparing Caltex Petrol vs Shell Vpower, and claiming Caltex no power...
also, there are Sharp models with/without pre-filters before the HEPA.
thanks

Sharp i'm comparing to the local ones. Think its the FU-A28E and FU-Y30E.

U go research lor, like i said it's your own due dilligence.

No pre-filters only means ioniser. So u are relying on your ioniser for bigger particles. Personally i believe in low tech solutions. Creating ions to float around to contact particles to bring them to the ground. Long term health implications i'm bit wary. Charcoal is only an adsorbent. So whatever floats past it can stick to it.
If got pre-filter great. Is it just a filter material? or charcoal? Filter material is like passing through a cloth so can wash. Charcoal from what i posted is not easy to reactivate back...

The more expensive models obviously have more stuff. For sharp, the higher end models have humidifiers Which i don't really want to pay for. especially if the person is using in a non aircon room.

The models i'm interested in are only 100-200 dollars but may have higher running costs over long term (which is what caveat emptor). But i do want to use these things when the haze comes back yearly.

bro i dunno man. There are lot of models out there.
I chose sharp cos it's easily available in singapore. And honeywell cos got a lot of info out there on it from USA users.
There are many good and expensive ones also.

Novita got in singapore, i never hear before.
Europace from europe. In USA, they have many brands and some are pretty high end and should be good. But ease of replacement parts is the major issue to me.

Like my family now has a very old HEPA filter from Philips. I search internet. whole world only 1 english website even list as available to buy the filter replacement. Like that how to buy ... mellow.gif

honestly speaking, i won't mind buying a sharp plasmacluster if it's available in singapore easily but i'm guessing its sold out pretty much when i checked few days ago. stuck at work, no time to go hunting around in the shops...

Amway is MLM, so you get a lot of excellent reviews on the net.

Can't understand why air purifiers in Singapore are so expensive relative to the same model sold in the states, it costs like 3 to 4 times more, incredible.
