I plan to buy an air purifier for a medium-size (~12 pings) living room. Since the famous Coway AP-1512HH is very hard to find here, I was planning to go with Honeywell HPA-200APTW until I read about their inefficient power consumption. I plan to run my air purifier 24x7 and don’t want to add 200NTD per month to the electricity bill with Honeywell.
Are there any affordable (at most 6000 NTD) and power-efficient air purifiers here with HEPA filters? Where can I find them?
I guess it just depends on what kind of particulates you are looking to filter out. If you just want to get rid of allergens or small particles like PM2.5, then I suppose any air purifier with a HEPA filter sufficient for your room size would do.
If you are also worried about Formaldehyde and VOC being slowly released from your decor and furniture inside your place, then HEPA filers alone aren’t going to cut it.
As for cost, you also need to factor in filter replacement.
By the way, they do sell Coway air purifiers here in Taiwan. Perhaps not that exact model, but I see many Coway models when I go to department stores.
I like how this one shows charts for the effectiveness for different particulates.
There’s air purifier made by a Singaporean company called Poiema that’s spending a lot on promotions lately. It claims that its filters can be washed, and doesn’t require replacement, and its TPA technology can neutralize Formaldehyde and VOC.
There’s a HEPA class too, i.e. not all HEPA are equal. We ended up with a Dyson because at the time we purchased a few years ago, its filter had the finest grade HEPA class. Things have probably changed since then though.
I’m aware of all the classes. The prices can easily go in tens of thousands of NT range if you go for the latest and greatest, so I just wanted a reasonably priced one with a True HEPA filter. The Coway AP-1512HH is super popular in the US and only $150 on Amazon right now, but unfortunately shipping to Taiwan is $170. They aren’t selling this model in Taiwan at the moment.
It’s at Costco guandu. I’ve owned two of these things and they’re pretty good! Costco lets you return if there’s any issues or you just don’t like how it looks. It’s easy to sell it after a year for 5k so it’s practically free. Keep the Costco receipt. Warranty is good for many years unlike some other brands.
If you go there you can grab two chicken pieces for 89 NT from their cafeteria and the free food samples
Also this can create some white noise if you have trouble sleeping or want to drown out some surrounding disturbances. I put it next to my bed when I sleep and I don’t hear the construction downstairs.
The honeywell one OP mentioned (which I have) doesn’t. My A/C units do though. But to measure I imagine it has to be blowing air so it would only be good at telling you when to turn it off and not passively let you know when to turn it on.
The Dyson auto mode does a reasonable job. A couple of times when the AQI has been high outside it automatically spins up high as you would expect. One morning I found it had cranked up after being on zero when we went to bed, I checked the AQI and one of those smog clouds had blown in.
