Air purifier? - Part 2

[WussRedXLi]

should be. It was recommended for air purifiers to have HEPA. Had been using one with HEPA. my sinus, runny nose now not as many as it was before

Great....another one more up point in the bag for HEPA effectiveness. Most of us have experienced this and read a lot on qoo10 reviews. Though still considered weak/unreliable anecdotal evidence, it's still cool as we can't do randomised clinical trials (RCTs) anyway, which is the gold standard.

BTW, these allergens/"particulate matter" is much larger in size than haze, absolutely no issue even with "unbranded Taobao HEPA". ie really unbranded stuff, not your XM or Mfresh, TCL, Midea filters even.

No qualms from me in running them and changing them twice a year, other than some slight complaints about having a slightly smell, and maybe a bit of formaldehyde outgassing from the glues in the initial few days (just air it good without pax in the room if one is ngeow and raise the temp of the HEPA in the sun as that increases the outgassing rapidly, electrical costs are negligible vs filter savings).

Probably HEPA filtration esp with a high ACH Air change per hour controls this source pollution pretty effectively? Vs dust mite droppings, coz on the beddings they are still somewhat heavy and don't really float that long a distance to be filtered by the AP. So limited in its help.

Just to be extremely clear in my text, anything in the AC has the ability to be airborne recirculated really solidly due to the blower wheel blasting air out of the FCU.....vs our turning on the bed action which disturbs the allergen (house mite droppings on the dirt etc) which is pretty slight only.

So the HEPA can filter the allergens/mold/whatever from the AC much easily and effectively.

Don't think Singapore sells ozone depleting products. It can cause harm to your health too. Not sure for Sharp, they have ionizing feature, but their price is high.

 

[Asakura]

there are. just that the amount are at the safe level.

did a search on xiaomi filters, it seems like they have a new type of filter. The purple colour which is anti-bacterial, not sure how it is compared to the green and blue one

Ya. Saw it too. Seems cheaper than the green. Interesting. Maybe next time can try this. A varieties, mixture.

Tired reading the info about the purple one, didnt see any HEPA words there. The anti bacterial one does not have activated carbon.

Can advise on the shipping fees and the price of the filter? I saw NTUC selling at $49.90.

It has been mentioned and confirmed many many times by me and the others in the taobao thread, 4PX and Simplypost-Ninjavan no volumetric weight in normal circumstances.

It is Ezbuy and some other 3rd party which play pattern in terms of volumetric weight.

I have even shipped pure EVA foam before, no volumetric weight. Lightweight foam/fur carpet, 1.1kg and relatively humongous 25cm x 25cm x 70cm, actual weight.
The only thing that is more volumetric is packing bubbles.


All HEPA, no volumetric weight, is actual. I always weigh them when it reaches......

They are for 300 x 400 x 24mm HEPA filters. Not Xiaomi filters. Just helping him to order and then self-collect, just a $10 service fee for the trouble coz he does not know how to order.
