 "Mostly Ineffective, Expensive to Maintain" 2010-08-22
By Robyn L. Brown (Upstate New York)
How does HEPA - and the companies who design products that rely on their filters - stay in business, if not for us desperate allergy sufferers who need a cheap air purifier and fast? But the long-term (and by long-term, I mean 3-6 months) cost doesn't justify the moderate to minor help these HEPA-style purifiers provide. It seems like a good investment, doesn't it? Under $50 and all. But wait, in 3-6 months comes the time you need to replace that HEPA filter that's been meticulously designed to be unwashable, no matter how innovative you try to be in extending its life. That new filter you need will be around $25 (at least at all the stores near me - or get them cheaper online but pay shipping). So will the next one you'll need a few months after that. The larger, tower version of this model requires TWO filters. Easy math - up to $50 to refresh that machine.



The logical person quickly figures out it's cheaper to throw the machine away and buy a new one rather than replace those filters more than once or twice. What crap. Companies need to stop encouraging this "disposable" mentality. Stop manipulating consumers and forcing them to increase the mass of waste in landfills. Stop treating us like idiots, offering low-cost machines that require expensive parts that need to be constantly replaced. We all need to stop putting up with this.



OK, but how well does it work? I once had an electrostatic air purifier. (It was from a wonderful company called EnviroResearch, that sadly isn't around anymore. I got that model for around $80. Oreck has since apparently stolen or "adopted" the same design and now sells a very similar machine for $349! But the EnviroResearch one brought me almost immediate relief from my allergy symptoms. I use that as my comparison.) I can see the filters in this purifier are trapping a lot of particles and dust. Yet for some reason, I experience no alleviation of my symptoms when closed up in a room with one of these. No reduction in dust building up around the room it's in, either. Time to break out the HEPA-filtered vacuum for the 7th time this week. I am a clean person, so it's pretty easy for me to determine how quickly dust is accumulating and these filters don't seem to slow that one bit. They just, as one reviewer cleverly pointed out, seem like a placebo.



One other thing. They cause drafts. The air doesn't come out straight out the front, but at what seems to be 45-degree angles on either side of the front. So it makes it hard to position these units anywhere where you're not getting a direct line of air blowing on you. Nice in summer maybe, but not so nice in winter.

 "Great product for small area" 2010-03-15

Works extremely well. Highest setting can be a bit loud, but mid settingis very quiet. Compact and un-noticeable. I would definitely recommend.

 "gotta love the placebo effect" 2010-02-26
By CAM
first off let me start out by saying that i've been using this 'purifier' in a 10x10 room for about 2 weeks now. i was looking for something that would help increase fresh air in the room while i partake in my 'herbal medicine' smoking. unfortunately, it didn't meet my standards. while it did, over time, decrease the odor of smoke somewhat, it was hard to really notice a difference unless i left the room and came back a half an hour or more later and by then the odor would have dissipated on its own anyways just as it did before i had purchased this product.



furthermore, even when there was no smoking going on in the room, when this thing was running with the door and window closed all day (which from what i've read in other reviews is apparently the only way it will work anyways) the room had a 'stuffy smell' when i entered it for the first time, again exactly as it would have before i even purchased this product. while i did notice *some* buildup on the filter after 2 weeks, indicating that at least a little bit of impurities were being filtered out of the air, it just wasn't enough to make any legit difference for me. this made me come to the conclusion that this thing is basically just an overpriced swanky looking small personal fan.



unfortunately i think most of the people reviewing this product are victims of the 'placebo effect'.. if you try hard enough to convince yourself that something is actually working, it's very easy to be misled. i have an extremely hard time believing that reviewers who state "i noticed an immediate difference!" actually experienced cleaner air. the product will be returned.

 "It's ok, but the filters too expensive." 2010-02-22
By daedelus7 (California)
I've used this for about 6 months now and it does a decent job, with a noticeable change in the smell of the room (this is due to the ionizer i think). Hasn't eliminated dust buildup on surfaces but dust buildup has reduced as far as I can tell.



However, now it is time to change the filter and I'm considering just getting a different purifier. Right now, a 2 pack of filters for the HAP412 are going for about $31. Considering that's almost the cost of the purifier (with 1 filter included), I'd suggest trying a purifier with a reusable/washable filter.



It's quiet enough on the lowest setting and seems to do an OK job purifying but ultimately the filters are way too expensive.

By S. Han
Works great in my room; especially in the desert of Iraq. Noisy at first, but after a few minutes, it quieted down.
