We got this to stop my wife and son from snizzing their heads off and it worked great.
"Energy Hog for second-rate cleaning." 2010-05-27
By C. Chiang (Baltimore, MD USA)
I am disappointed for 3 reasons:
1. The Honeywell HHT-081 is an energy hog. I have a Kill-A-Watt(tm) meter that can tell me the wattage and power consumption of anything plugged into it. This air purifier consumes 41 watts on low, 63 watts on medium, and 98 watts on high (ionizer on or off has no measurable effect on wattage). I suppose this means running on high 24/7 will cost about $8.50 per month, but compared to other higher quality air purifiers, a low setting of 41 watts and a high setting of nearly 100 watts is quite shameful. For example, the RabbitAir BioGS SPA-421A consumes between 7-33 watts. Honeywell does not make technical specs of their products available, so I cannot compare air flow rates between the two... But, it's common sense that the HHT-081 probably does not put out 3 times the air of the RabbitAir BioGS SPA-421, even though it's consuming 3 times the energy...
2. The HHT-081 is a hepa-TYPE filter. hepa-TYPE is not TRUE-hepa. Meaning, it's not really hepa, but it's similarly shaped. HEPA-type filters trap only the largest of the range of particles, leaving the smallest ones (presumably also quite problem-causing) to flow through freely. If you only want to clean out visible dust, this isn't a problem. But, if you have allergy problems, HEPA-type filters will not solve your problem. I bought this knowing it wasn't a true HEPA, for cheap extra low-end dust-filtering to support my higher quality unit... But, running at 100 watts, I feel like I'm pouring energy down the drain for third-rate cleaning.
You may say, "but true-HEPA filters are expensive to replace!". It's true that they are expensive. But any decently designed air purifier that has a true HEPA filter will have a washable pre-filter that catches larger dust particles- leaving the only the smallest particles for the HEPA filter. This way, the HEPA filter is not clogged up with large particles of dust. Such designs allow for filter replacement costs between $30-$80 per year - this includes buying both a HEPA filter and an Activated Carbon filter. (such as the Sharp Plasmacluster or any of the RabbitAir models)
3. You have no idea what you're buying. By that, I mean: Honeywell has a suspicious lack of technical specifications for its air purifiers (unless the particular quality is somewhat notable). Any other higher quality manufacturer will have plenty of technical specifications available. How loud is this unit? No technical data. How much energy does it consume? No data. What kind of air flow comes out of it? No data. How large of a room can it clean? Hardly any data. Air changes per hour in a room of a certain size? No luck here. The only thing available is the CADR rating, and I would cation against judging a product by its CADR. CADR measures how fast a model can spew out cleaned air in a 20 minute period. It does not take into account energy efficiency, loudness, long-term durability, ease of use, etc... You wouldn't buy a car based on how well it performed in a drag race, would you?
IN CONCLUSION, while I am only spending $90 for this model, I get energy-expensive second-rate cleaning. Looking back, I would rather have spent a little extra ($160 to be exact) to get a RabbitAir BioGS or something of that quality, because the HHT-081 is nothing but an inefficient fan combined with the pre-filter of a higher quality air purifier.
"air purifier" 2010-02-12

good air purifier. Easy to use. Relatively quiet. But could use a timer.
"I would buy it again. No regrets." 2009-09-02
By K. McCaskey (Los Angeles)
I have severe allergies in September. I think ragweed is what does it and I live in Southern California, so the wildfires that spring up during this time don't help. I use this filter during this time and it helps me so much. I go from having hay fever to just having a stuffy nose. If you have ever had hay fever, then you know stuffy nose is a great improvement. I have used this in an 8x8 office, a 12x12 bedroom and in a 15x20 room. Obviously the smaller the room, the more effective, but I think it helps in the larger room as well. I use it with a portable A/C in the largest room, so that A/C is pushing out air and filtering the inside air as well. Without bringing in new air from outside.
I think it works well and makes a slight humming noise on the lower settings. A bit of a rattle on the highest setting. I can't sleep with it on high. The 2 lower settings are actually great white noise for sleeping. It is light and easily portable.
"Started chattering after a few months" 2009-04-02
By Jim D. Shelton (Santee, CA United States)
Seemed to clean the air pretty well and certainly liked the small-footprint tower design. But after a few months it now chatters loudly and is no longer useable. I didn't see anything obvious but sounds like something has broken internally. Guess I can get it fixed under warranty...if I can find the receipt. Decided to just replace it with a different model. I've good luck with Honeywell before but wouldn't recommend this model.
