Our Honeywell air purifiers from Amazon are here!

Update: I've found some deals on eBay which are worth a look.

Earlier, I posted about air purifiers for the haze. I am pleased to report that they arrived in a mere NINE days, using the cheapest shipping option (which isn't at all cheap, by the way). I had ordered them on 13th July, as I did my first post on the topic. They arrived on 22nd July.


I don't know why I had one "gift-wrapped"...
 
Beefed-up (relative to the first one) transformer for the more powerful purifier

Looks a lot nicer than the other one


I only did this update now, as the winds have brought a bit of the haze back to SG. Otherwise, I know most Singaporeans have forgotten the impact and intensity of the 400 PSI haze, and nobody will read this post. Today's haze smells pretty bad but AQI really isn't that bad. It's still in the moderate range, and AQI factors PM2.5 into the equation.

PSI readings are still "good" though. If you believe in placebos, read "the right things" and avoid this website. It sure is cheaper in the short term to take no precautions to protect yourself.
As I mentioned in the previous post, the four purifiers I bought (one from a friend, three from Amazon) were for my family, and my in-laws'. I thought that the haze was gone after Vivian gave that envelope to his Indonesian friend. But after Vivian said that the haze was coming back, I decided to bring home the oldest and lowest capacity Honeywell, the one that I wrote about previously.

I wonder what was in that envelope. Not that I mind, because it seemed to work!

I am happy to report that it works well enough. I cannot say how how efficient the filtration is, but I have been running the purifier overnight for the past week, and closing all our windows in the event the haze snuck up on us. My efforts paid off last night. This morning, I detected a slight haze smell in the rest of the house (I use air con at night), and noticed two Facebook status updates about the hazy smell. There was no smell whatsoever in our bedroom!

The smell outside was far worse. I guess this is largely a "smelly haze", which doesn't affect visibility much and doesn't register too steep a decline in air quality. Sorry for the unscientific description but I guess that's what it is.

So if a rather well-used low-capacity air purifier works, you can be sure that those Amazonian Honeywells will work even better. Those clean a much larger volume of air, but the trade-off is that they are somewhat noisier, and consume more electricity at full blast (90W vs 180W).

video
Here is a video I took of the Honeywell Enviracare HEPA purifier to illustrate the noise level. It's noisier as it emits the air through a much narrower opening, and a lot more air too.

My recommendation is to crank it up once you get home, and turn it down only before you go to bed unless you like this sort of white noise. Given that these things run on transformers, I would NOT recommend that you leave it running when you are not home, in the event of overheating. My friend has tested these to near overload conditions, and his findings are that it auto cuts off due to overheating. Which is good, but no harm playing extra safe.

These things are the same physical size as the Honeywell SilentComfort series that I first got, and am running at my house now. The SilentComfort is designed to be much quieter, mainly by having a much larger exhaust (in this case, exhaust is clean air). The airflow feels deceptively mild, but that's what helps it run silently and effectively.

The Enviracare sucks through a large intake and jets the clean air out through the narrower opening. I could really feel the draught while testing it. Its lowest setting is slightly noisier than the SilentComfort.

Value-for-money wise, just get the Enviracare unless noise is a bigger issue.

You could buy these here and have "after-sales service" and a warranty, but be prepared to pay at least double the price. The good thing is that buying locally-sold sets (from a proper retailer, because I can imagine some people bringing in US-spec sets) will eliminate the need for a transformer. That should save a bit on electricity as well as make the whole setup somewhat safer.

  1. Hi, after 2 about 2 weeks of usage, are you still as happy with new Honeywell air purifier. I am planning to get one but the noise I hear from your video is making me think twice. I read the same issue from reviews at amazon too. As for the SilentComfort model, there are no reviews whatsoever from the link you gave. So I am still waiting for the "perfect" air purifier while my lungs hang in there and suck it up.

    1. Hi Anon,

      The EnviraCare is significantly noisier. In fact it is slightly noisier in the lowest setting than the SilentComfort in the high setting. But I think even if noise is a concern, it's far better to clean the air in the day and switch it off at night if you really can't sleep with it on.

      The SilentComfort may be the better compromise overall, but the EnviraCare does give you much more Air cleaning capacity for your dollar. No regrets whatsoever

      Now it's easy to say 'hang in there and suck it up'. I hope the air stays like this but I am prepared for it to turn otherwise.

      One event is even more of a given than forest fires, that is the 7th month burnings. I'd use them then.

      Even though my family and I have not had these luxuries before, better late than never, I guess... it's like quitting smoking in a small way IMHO.

  2. Hey NR,

    I was wondering what is your take on using either an EnviraCare or SilentComfort without using an air conditioner at all? Does that mean most, if not all, the clean air would go to waste? (My skin is way, way too dry to use an a/c and my bank account happily is in the same camp of not using more electricity than necessary.)

    1. You have to shut the windows otherwise it is pointless.

      Aircon or not, up to your comfort. It's recirculated air as long as the windows are closed. Of course unless you live in a Tupperware, I'd imagine oxygen and pollutants still diffuse in, and carbon dioxide will diffuse out.

      I run the Aircon because I can't take the heat and humidity. $$$ but I can't have it any other way...

  3. where did you get the transformer? how much does it cost?

    ReplyDelete
  4. You can get it from Sim Lim Tower basement. Not sim lim square ah...

    Cheaper one can be had from about 50+, but get one with more than enough wattage to power your purifier...

    1. I bought spare pre filters but not the HEPA filter. The HEPA element is supposed to last quite a few years with occasional usage

  6. Hi. I think I've deleted the invoices but it works out to about $400 per purifier, with shipping and transformer. You have to check out the prices on Amazon and work it out for yourself.

    Also consider buying from Australia. I don't have any sites to recommend, though I just picked a brand new second hand one for $150 from Gumtree, with spare filters and pre filters included.

    Why buy from Australia (or really, any other country with 240V supply)? Simple. You don't need the hassle and expense of a transformer. Just use a travel adaptor and you are set.

    I do think Amazon has the best deals though.

  7. Thanks for the prompt reply, my sinus is killing me now... Really need a good air purifier to clean the air in my house :(

  8. No problem. In the meantime I guess you could try N95 masks. And see if your air-conditioning system (if you use one) needs a good servicing.

    I tried a servicing once and it seemed to reduce the "old air con smell" somewhat. And they managed to get a lot of crap out of the system as well. I think cleaning the filters only does so much.

    Glad that we have hardly ever had to use the aircon in the six weeks we've been in Melbourne! Even if we have a heatwave here, I'm assuming what.. two weeks of aircon usage in the day time (that's only when we are home...).

    The air is way better over here. I don't think this post on purifiers is such a helpful post because it doesn't address the root of your problem: you being in SG.

  10. Hi do u get waranteed if u get the Honeywell from Amazon ?

    ReplyDelete

    1. Probably. If you send it back to Honeywell USA and they don't know it was run on transformer from 240V supply.

      I was just telling a friend that this things are very simple gadgets. Little more than an air blower encased in a housing which forces the air through filter media.. I would love to have warranty for that but my worry about clean air supersedes any worry over warranty issues.

      Can't remember if i've mentioned it before on NRSC but we are using an Australian Honeywell set in Melbourne, bought used for A$150 off Gumtree. No warranty.

  11. Hi , do u have the link to the set in GumTree because I couldn't find it . Btw that's for the prompt reply . Was deciding if I wanna get it from Amazon or just from best denki n not worry abt the transformer part. But the price difference is really... T.T

    1. Hey Miss Pepper,

      Gumtree is a free classifieds service. The Honeywell ad which I bought mine off is almost certainly deleted by now because the purifier is sitting in my cupboard now. There might be a couple of other suitable HEPA units from other brands if you bother looking.

      If you are willing to make a few overseas calls, you could trawl Gumtree for purifiers and ask if they are willing to have it shipped over. I saw a Blueair basic one in Melbourne going for $150. Not sure if it's still there but I'm not making this my sideline.

      If you buy it from Oz, you just need an adaptor head. No need transformer. It's cheap too, if it's used. Way cheaper than what you can get for new in SG.

      But again, no warranty and I don't know how much you trust online sellers.

      I say I'm not making this my sideline because if you add on shipping cost and a small token fee to me for all my time and trouble and petrol cost, probably no one would want to take me up on that. And I sure as heck would not want to deal with any "after sales" issues either.

  12. Hey do you happen to know (or how to know :D) the transformer wattage requirement for the Honeywell SilentComfort Permanent, True HEPA Air Purifier, 18155 ? Its a slightly updated model of the one you purchased. thanks for sharing :)

    1. I also bought Honeywell SilentComfort Permanent, True HEPA Air Purifier, 18155 from amazon and intend to use a 200W voltage converter.
      I am not use if a 200W voltage converter is able to support 8 hrs of usage ? Should I get a 200W voltage converter instead ?

    2. Normally you don't run it on full-power all the time. Full-power is only for the first 15 minutes or so when you first reach home.

      Your numbers don't make sense to me, but just follow the formula I have spoon fed to you guys and you should be fine.

      Remember to duct tape the plug to the transformer so that you don't end up like that other champion here whose family member ran the purifier without transformer and killed it.

  13. You Google the specs (or wait for the purifier to reach your place first), then find out the amps and voltage specs. Voltage should be 120V or 110V.

    Power in watts = Amps x Volts.

  15. Hi thanks for the info that you post. Really helpful. May I know its cmg to 10 months. Does your air purifier & transformer gets overheated or very hot? Thanks.

    ReplyDelete
  16. Hi Chris. Not the air purifier. Transformer felt hot like a cheap Acer power adaptor. If you know what I mean. That's under continuous full blast usage. I wouldn't use it outdoors under the sun but I think it's ok for indoors usage. Anyway if you smell something burning in the house... you know what to do

    Bear in mind I don't use those things anymore as I have a 240V Aussie set here and the air quality here is almost always superb except for a week or so during the most intense bushfires (and when the wind didn't cooperate to disperse pollutants)

  17. Hi,

    I bought this honeywell 50250 from amazon last year and someone in my house accidentally on it without transformer and spoiled now. I don't know where I can repair this in singapore. Does anyone have any idea where I can repair? I have no idea if there is honeywell service center in singapore. i can't find website. appreciate if anyone can reply this. thanks

    1. I think you have to ship it back to US if you want it repaired. Personally, I wouldn't bother.

      I doubt you can get it repaired at a cost which makes it more sensible for repair, than for you to buy another one.

      Next time, duct tape the purifier plug to the transformer so that it cannot be removed easily

    3. Hello! If y'all do see this, please try to help me out! I'm from Singapore too, and I'm hoping to get the same honeywell from Amazon as well! But because it's more than 300$ after shipping, I'm super worried that it'd get lost on the way. I haven't made purchases from Amazon before. Do y'all know if the standard shipping is trackable and if Amazon is responsible for lost items? I'm pretty desperate to get a new honeywell with loud white noise cause the one I have (and is faulty now) is noisy like that and I can't get used to sleeping without the white noise:/

    4. Hi Vivian,

      I'm not sure if standard shipping is trackable. But there should be an upgraded shipping option which would definitely be.

      You have to try to click through to just before the Checkout page, and read the details/ T&C on shipping.

      In all my purchases from various shopping portals (Amazon, eBay, Qoo10, Kogan, Leisurepro, Chain Reaction Cycles, etc etc), even through some 'fly by night' sellers, I've never not received anything. If that ever happens I'd try my luck with the seller. There's feedback avenues and usually they get pretty concerned with negative feedback.

  21. Did you mean gumtree. Did it come with 240V standard? All sites lead back to Amazon of sorts and Amazon does not ship that product to Australia.

    ReplyDelete
  22. I gather it can only be purchased overseas (ie. singapore) where amazon does ship this product to. If you did get one from Aus it was probably brought in same and you fortunate enough to get it?
