Air purifier?

[Pandaeyed]

Was at Westgate just now. Saw abt 4 sets of Sharp Purifiers on sale at Gaincity.. At abt $4xx plus, its the model with the mosquito trap. Just a heads up incase any bros still looking for Sharp.

 

[Akai Ryu]

Yes I agreed.

The world has more than just AX40 albeit it is quite readily available from qoo10.

Based on the figure assuming 99.9% efficiency cadr is 180m3/h at max speed which is pretty decent.

But at such low wattage, I dare to say that the air outlet speed is low and too low to prevent short circuit. Ap must also be powerful enough to circulate the clean air around the room.

The idea for this ap is allow user switch on 247.

The e2f filter is also same as that puny 'amazing air purifier' at qoo10 which state that its washable. But clair only state vacc and need for replacment by 18th month.

I would probably use this at office desk or as hepa ap compliment and put bedside.

Low electricity consumption is good for environment

Hepa will still dominate market...it was afterall developed to filter air in nuclear facility

 

[Akai Ryu]

Same e2f filter in claire but market as e-nano filter here. State washable as well just like that puny 'amazing air purifier' which has different names when i saw it at Qoo, amazon etc

 

[kandinsky]

wtf...if never remove bag and the AP keep throwing out air, never get choke?

So much resistance, surprised the fan motor didn't burn out... AX40 quality must be there

Yeah, to me the figures really look suspect (aka inflated). 5W can get 180m3/h CADR sounds like some kind of sorcery.

Actually how many input were not so important than human healthy.
Get lesser sick you are easily earn back from the medical fee.

Just few watts only if compare to AC just like a peanut wow
Maybe I am wrong

40W AP running 24/7/365

Running cost $81 excluding filters.

Assumption TB filters $40 and ap last 10 years

Life cycle cost 10 years x ($81 + 2 x $40) = $1610

Half cost of running is electricity.

I am particular cos maybe I am poor.

I still dont see the use when the air circulation is bad. Only the localised near the ap will be clean.

In a house with Windows closed, clean air circulation is very poor.

My pm counters do not come with a fan, and they will under report pm count until I shake it or blow air to bring surrounding air.

You will need a fan to assist the AP as Wrx said before, a medium sized fan uses 25-30 W so it defeat the purpose.

Yup which is y i may consider for office desk space. With USB fan and surround with plants. Office no need too good an ap but i wanna use free electricity and not buy replacement filter for office ap

 

[Akai Ryu]

Happened in my office until i opened up to check.

Mine have some ap with missing hepa even so end up the ap just an air circulator

hahaha ya that I agree
I also looking for one in office, desk type one, don't want to spend to buy a big one, that one is for boss to buy.

But I measure the air quality in my office, normalised to nea is only 15u/m3, cleaner than my house with ap on so it's not too bad.

Depends on your office ac i guess...some centralised ac have filter ducts and contractors to clean the ducts. Sigh...ex water minister will say ac is enuff

But not all ac environment good, even if particulates low. Having an ap near u can filter voc, bacteria virus etc meaning u become a better employee who doesnt need to take medical leave as often lol

I knew i am poor too, but just drink less of coffee per daily.

Received my AX40 ordered from HappyMall, going to place in the hall. Took 6 days to reach. Just in time for the hazy.

Anyone can recommend any particle counter?

 

[xyz2006]

Its the same tb seller which alot here custom their hepa for AX40

Is the same TB seller that I PM to you?

I was quite interested in go-clair. I suspect it doesn't have large enough airflow since it's so small, but it will be interesting if you can post some data.

Just saying "tested and not recommend" doesn't help.

Since it uses way lesser energy, like 5W for their flagship model on max speed, plus a 35db, the trade off is exactly that. The best way to test it will be to enclose it inside a room for 24 hours and test it against whichever model you have that's HEPA.

Off the top of my head, since its 5W, it's ideal to run it 24x7, and keep the door closed most of the time to keep optimum. Compared to larger airflow HEPA, it has to be switched on high everytime you are in the room, and ideally 8 to 12 hours.

5W x 24 hours = 120W
35W x 8 hours = 280W

Which is why i also do not agree with the "it doesn't work" comments without data.

Not much point in writing about my flawed tests which was also lacking data and proper tools, so I will just post some B4 values as I have both Go-Clair and B4 on hand. Take it with a pinch of salt.

100~µg/m³ B4 readings at surrounding area, 55~µg/m³ B4 reading (intake facing directly at the output air from go-clair at highest speed (which should be described as a breeze)). Running it the whole day does squat for the PM2.5 concentrations here. The area is probably too big for it.

I yet to see good concentrations of PM2.5 (on the B4) in the living room which runs the Airvax almost 24/7..at most there is a 10~30 difference in the reading...Again the area is probably too big, and too much air leaks in from the closed door and windows.

I suspect what Akai Ryu says about these devices should be right, for running 24/7, but not for cleaning up haze at our current concentrations or to be used in large areas. Probably run a strong AP to clean the air beforehand and leaving this device on in a small room...?

Anyways why don't you ask the companies who produce this thing for numbers rather than myself...

But personally I would avoid using them for our Haze related issue.

Yup was hoping for alternative seller

 

[Akai Ryu]

Not i say one...coy website market it as good 247 ap

Yes possibly good if wanna use "traditional " hepa ap to scrub air to good level and let this static filter ap mantain air quality when not at home.

You are right though, I did PM them on FB and here's what they say :


The e2F filter is a new patented technology, so you will not see any other competitors with the e2F filter. In terms of "scientific review", the best we can do is show the results of our 0.3 um and 0.1 um tests:

cdn.shopify.com/s/files/1/0640/4627/files/0.3um_Test_report_air_cleaning_capacity.pdf

cdn.shopify.com/s/files/1/0640/4627/files/0.1um_Test_report_air_cleaning_capacity.pdf

We do not provide a CADR rating because we do not agree with that rating system. The CADR is flawed in the sense that the way the test is designed inherently favors air purifiers that can push out a large amount of air over air purifiers that can clean the air more efficiently, but with the result of less air volume pushed out by the unit. Our air purifiers put efficiency above all else.

To be frank, almost any manufacturer can get "certified" with the CADR rating as long as they pay the annual fees to the AHAM (Association of Home Appliance Manufacturers). There are other reputable air purifier manufacturers who have taken a similar stance as us and do not provide a CADR.

While we do not have a comparison video (I am not a lawyer, but that could be a bit risky, legally speaking), we do provide a comparison chart, so you can see all the specifications of other air purifiers side by side.

twisted argument about cadr

cadr = flow rate x filter efficiency

480 x 0.85 or 180 x 1.00

which one better so need me to say

and of cos you need money to pay for certification.

what twisted logic

From the PDF: "The flow rate of the specimen was less than 1 m3/min. So four specimens were used for the test."

So in the test they used 4 air purifiers, AND a 'mixing fan', in a sealed ~100 sq feet chamber (assuming a 9 ft ceiling)...

An ideal air purifier should be able to do 5 air changes/hour... (4 of these and an extra fan, in a sealed room) would take ~5 hours to do 1 air change (? based on my sloppy math).

I have one my bedside table. It probably keeps the table slightly less dusty but that's it. If you go on Youtube there's a reason why the demonstrations all put it in a tiny smoke chamber.
