Air purifier? - Part 2

[sehsuan]

The catch is it's not $176.
It's $218.

TB still cheaper

does that mean, add a filter (since the image shows NONE) and you'd have to add 50 SGD more for 267 sgd?

come come, like that i can do another MO liao haha

 

[testerjp]

The QnA below says it come with just one.

So the $50 is for extra.

 

[WussRedXLi]

Doh.....always forget to choose below options.

Thanks for sharing.

I just wonder how Poiema can make an air purifier so different. (@@! 60 patented technologies..omg)

Now I am waiting for my delivery of P800. Maybe I can give a review also.

However, haze is really in singapore now. I can feel it when I am driving.

Hope it won't be too serious this year.

Why would anyone care if patented or nt.. We also not scientist.. Main thing is whether its value for money and works

Not really, according to my screenshot.

Total price is $218 with delivery.

I think he cunningly reduce the selling price of the item to appear $176 and add the $16 shipping fee. The low selling price as you can see earlier makes people thought it's a good deal.

Overall not that bad price but i got it for $184 with 65DG, maybe this may arrive a few days faster.

Some geek talk :

BTW, I think some of you might have seen the slight argument over at the $279 Xiaomi Air Purifier thread regarding someone asking for folks to go for Blueair as it's certified by so and so and also US Embassies/Consulates are using Blueair (?? not sure if this is true, never google, i'll take it as it is true) simply because they can filter Anthrax.

I really don't wanna continue that kinda conversation and discussion over there already.
But I think you folks here know better. These risks are nearly non-existent in Singapore.

Just the facts here :

Facts
1. HEPA was and is still is recommended for radioactive fallout and biological biohazard stuff like anthrax. HEPA was actually developed due to this radioactive and biological risks way back then in the 40s or 50s.
The internet is full of this info, HEPA tests for radioactive ask is all over the youtube. I cannot lie with regards to this.

Anyway some links : This is what CDC has to say regarding Anthrax
HEPA/Vaccine Plan for Indoor Anthrax Remediation
http://wwwnc.cdc.gov/eid/article/11/1/04-0635_article

To advance the analysis of these recovery options, we propose and evaluate a very simple HEPA/vaccine plan, where HEPA air cleaners continuously clean the indoor air and Hazmat workers use HEPA vacuums to clean the floors, walls, ceilings, and room contents on a twice-a-day basis; HEPA filters are 99.97% effective for 0.3-μm particles (3), which are 5–10 times smaller than a typical anthrax spore.

^^^^^

So ultimately in the end, what matters is still CADR airflow.

And yes, technically, the Xiaomi AP with the H11 nearly H12 filter would still be able to handle stuff like Anthrax, piece of cake.

GVGT.

This is the 3M Filtrete furnace filter. I don't think it's the best MPR2200 version (MERV-13). That one is H10.

Absolutely no issue with radon gas decayed products (Polonium 218 and Polonium 214, they impart the greatest alpha radiation to your lung lining cells epithelium) sticking to dust particles/smog haze/air pollutants or whatever shiat stuff that might have brought in by the wind. Eg, Fukushima and USA/Canada via the Jetstream.

But no worries, say no to fear-mongering. We don't have such issues here for HDBs, not at a high level vs other countries. But it's interesting information that's good to know.

ONLY SMOKERS GET LUNG CANCER


Fact: Anyone can develop this disease, though current and former smokers are at a higher risk.

As many as 20 per cent of the people who die of lung cancer do not smoke or use any other form of tobacco. Some of the other risk factors include:

Radon gas: This gas occurs naturally outdoors in harmless amounts, but it can get trapped in houses and buildings. Studies have found that lung cancer risk is higher in those who have lived for many years in a radon-contaminated house.

As radon gas is an odourless gas that cannot be seen, the only way to know whether it is a problem in one's home is to test for it. Unfortunately, we do not have data on radon levels in Singapore.

Second-hand smoke: Each year, an estimated 7,000 adults die of lung cancer as a result of breathing in second-hand smoke. Laws that ban smoking in public places have helped to reduce this danger.

Cancer-causing agents at work: Some workplaces can expose one to carcinogens or cancer-causing agents, like asbestos and diesel exhaust. If you work around these agents, you should limit your exposure whenever possible.

Air pollution: It has long been known that both indoor and outdoor air pollution contribute to lung cancer. In 2013, the World Health Organisation classified outdoor air pollution as a carcinogen.

PS. It is not only haze that increases the risk of lung cancer (very very low), but rather the annual PM2.5 exposure. The risk for heart attacks, heart diseases like ischemic stroke is relatively much much higher vs lung cancer for the levels we experience here. (you gotta go to Indonesian cities like Palembang/Palangkaraya to have a good spike in risk for lung cancer). But do not compare Singapore's biomass haze vs China's smog, concentration ug/m3 for ug/m3, China's smog is much higher risk due to heavy metals found there like arsenic, cadmium etc.


PPS. EPA has done a big study with regards to cancer risk of wood smoke vs diesel exhaust smoke. The lung cancer risk is 3X that of wood smoke at the same concentration. Fortunately, at present we don't have a big issue with diesel exhaust smoke due to the latest Euro standards (other countries are Euroless or Euro II at best). But maybe you'd still take note if you live beside an expressway, eg Sims Drive just 40m from PIE.

Radon test kit from Amazon. Eligible for free ship to SG.

May be useful for landed property owners esp those without good ventilation? I have been to a few houses which are super jialet in ventilation (the buggers don't even open the windows, maybe due to inconvenience or bugs). I don't know man.....

Tokyo > 100,000 Bq/kg in the dust via Cesium 137 as detected by gamma spectroscopy

 

[testerjp]

That's why i am concern about VOC and wondering where can i find a kit to test efficiently

 

[WussRedXLi]

Well, for one, Radon is not a VOC. It's a gas. The lucky thing is that the resultant cancerous dust that carries the the Polonium-214 decayed daughter products is filtered by HEPA. Also, I don't think we have much of an issue in Singapore, definitely not for HDB units that are above 3rd sty.

For landed, I really don't know. As noted, I noticed some landed property folks like to keep their ground sty windows shut all the time, they do many more windows than the typical HDB I guess + various other factors. Do note that there has not been a single study done here. For other countries like in UK (Europe) and USA/Canada, they do map out the country in terms of radon risk. But they do have a much higher percentage of landed property kind of houses there instead of apartments vs SG - it's probably a more critical issue for them.

Secondly, we usually do not have VOCs in the house unless if it's new (not always also and most times not hazardous range) so rest easy. Some new furniture in the room like cabinet may release formaldehyde as well.

So don't really have to waste your money. Just leave a slight gap of 5mm at your windows will do, so that together with the door gap at the bottom there is a mini circulation going on, it works for CO2 too (I have a CO2 meter). 2 pax in those small BTO bedrooms with closed doors and windows eg aircon room can spike the CO2 levels to over 1000ppm within 30 mins and can hit 4000 ppm over the course of 1 night, which is quite high. This is not only my measurement/findings, but also by others on the net like in China/USA as well.

CO2 - 8hrs avg

If my house very old, furniture above five years, still need to worry about VOC?

 

[testerjp]

Those ordering from taobao the cheap hepa for ax40.
The seller says order nine can fit just nice to one medium size carton.

My ax40 from qoo just arrived, the first one bought from this seller call daiso.
The Goni seller haven even ship yet.

So I can stick it close to the wall?
The backside where the filter is exposed will do?
Should place close to air con or window?

There will only be a wee bit.
