I am completely ecstatic with this air purifier.
Design: Very sleek design, with blue light up buttons.
Noise: Unless you can't even stand the hum from a laptop, this purifier is really quiet. Even on the highest setting, you can tune it out very easily. On the lowest setting, you can't hear it at all.
Quality: When we brought it home and hooked it up, we noticed it working almost immediately. We have an old heater, so it still has that musty smell whenever we turn it on, this got rid of the smell so fast. Also, we self-medicate, so this got rid of the smell so quickly-- our apartment smells so pleasant now, and the air feels so clean, I would definitely recommend this product.
Perks: No replacement filter, you simply clean the same one.
- Notification for Filter Cleaning
- replaceable UV light bulb, only needs to be replaced once a year.
- Stand-up design.

i also got this unit for 80 bucks with the coupon at costco. i think it works well. i have very bad allergies and live in a dusty house. i got three of these and now my allergies are much better and the house is much less dusty to the point where friends have noticed. i did not notice the plastic smell mentioned in the other review. however, this fan is very noisy on its highest fan speed which is annoying. also, it makes the house feel like the air conditioner is on which the rest of my family complains about. i leave it on low when people are in the room and when they leave i turn it back to high: problem solved. other than that, this is a good purifier. the filter is easy to clean. i have already cleaned it with my vaccum brush. it claims to remove some bacteria, viruses, and mold from the air which is always good. it didn't impress me in terms of clearing out fumes when i used it for that (after having new windows installed), but for dander, dust, and things of that nature it is a really good machine.

I purchased one of these filters and saw it instantly clean the air. When the sun shines in the window, you could see the dust floating in the air. After using the filter for just a few minutes the dust particles were gone. Due to that, my family purchased two more units to put my our bedrooms. Since then we have noticed that our sinus build up is gone. I sleep better and sneezing in spring is pratically gone.
I highly recommend this unit. We didn't have any smell from the plastic as the other user commented. We also purchased the unit at Costco for $79 with a $40 rebate from Ameren Electric.

Using for 2 months, bought thru coupons@Costco. I did NOT encounter ANY plastic smell, etc. when I started using it, 1st. time. Design wise - very well done and stands solid (does not easily tip over). LCD panel, well lit and buttons are well placed. Weight is very okay and has a handle on top, which is a real good feature. Has a timer, going from 00 to 24 in hour increments, which is useful.
Few things to note: Although no one cares but it's worth while to peruse the manual. My unit wasn't working that great till I figured out to keep AT LEAST 12-inches away from obstructions. Next, in NIGHT mode, all things work as-is except the lights are shut down in LCD panel, which helps me to sleep!
Quality of air cleaning: Takes some time but I believe it's working since I have less dust, my sinus issues have noticeably got better and I was having off and on burning eyes which I don't get anymore. I live in a very old townhouse where when I entered from outside used to get a musky smell, which I don't get anymore. But note: It's designed for 200 sq. ft and thus I use it in my bedroom when I sleep and carry it downstairs to living/dining area when awake ; always at the lowest speed setting and thus it takes a bit of a while but slowly over time things have improved and now at optimal stage. At this price point (I paid $80) I think it's very good value buy. It's removing dust, pollen, mold, mildew and some odors. I don't smoke so can't comment on tobacco smoke.
A good feature is ability to use it only HEPA filter or HEPA + UV and volatile substance filter (odors). UV light's life is 3 years and thus it's good to know it can be switched on/off. Total power consumption is 3W: UV and 60W: purifier fan at highest speed. Based on the CADR published, it seems it's Energy Star qualified.
Negatives - extremely loud at highest speed and it's CADR ratings are to the best of my knowledge is built on the highest speed. Thus, effectively it'll take some time to get things "going", i.e. clean at lower speed. Also, there's no automatic start/stop based on sensing odors or dust or etc., etc. effectively forcing someone to keep it always running. The warranty is ONLY ONE YEAR, which I find to be pretty bad since most of good quality air purifiers I see are around 3 to 5 years warranty. This calls to question the quality of the product, only time will tell.
B4 someone really buys it, remember it's required to clean it monthly. I do it regularly and thus it's working good. Also, it blows cold air like any other purifier. In winter, for some might be an issue. A neat trick I do is actually use it with the inlet vent facing the room and in fact found it to be performing better!
Missing: remote, would have been really good. Also, if it oscillated would have been better. The plastic is cheap.

My Thera Pure air cleaner which worked for only 7 days!!!! It has a one year warranty - to exercise the warranty I MUST pay $29.95 and they will ship me a new machine and then I MUST ship the old machine back - which will cost an additional $20-30 by UPS or FEDEX - The machine cost $98.99 - so to exercise the warranty I must pay about 50% MORE money to get a working machine. My Thera Pure cost more than $14 per use. The company is devoid of integrity and DOES NOT STAND BEHIND THEIR PRODUCT - they also employ persons who speak English so poorly that it is nearly impossible to understand them. When I asked to speak to a supervisor to lodge my complaint - they refused to connect me to one. Avoid products from this company.

I bought this at Walmart and had it running for less than a month. It developed a squeak which gradually grew louder until one evening, I couldn't get it to turn on. I read some other reviews and decided not to bother going after the company for a replacement, but I will say I'm not happy with the prouct. Save your money.

I also bought 3 from Costco. I am taking them back. I didn't realize until I got them home that it actually says "HEPA-type" filtration and not HEPA filters. I've used them on the highest settings for 3 weeks and allergies are a TON worse! I thought maybe it was just me, but I pulled the filters off and there is very little cat hair on them and they don't look dirty at all. For that amount of time in this household, I should have been able to see the dust (we live in a horribly dusty area). I feel like the fans were just blowing dust and pollens around the house. We started sneezing the day we turned them on, and not one of us has stopped since. These are all going back to Costco. We'll try a true HEPA this time.

i bought this from Costco for $79.99 with $20 discounts on Jan. 24, 2014. On March 18, 2014, the signal "clean the filter" turned on in red. I cleaned the filter in accordance with the instruction. After cleaning the filter and returned the grill back, the air
purifier won't turn on, will return to Costco for refund.

I got this unit from costco (eighty dollars with a coupon, a hundred without). Its model number, Therapure 240, seems to be a customized version for wholesale clubs as it is not sold directly thorough the Envion web site. Visually, at first glance, the unit makes very good impression. It has a beautiful design and is whisper quite on the slow fan speed. It is a little noisier at medium fan speed, but tolerably so. At the third, highest fan speed it is fairly noisy and annoying. Which is a problem, because air purifiers are rated based on the volume of air which they can pump though the filter in a minute. This particular one is rated to purify air in a 200 sq. feet room. It is my understanding that it can do it at the highest (noisy) fan setting. At the tolerable middle setting it will likely be good enough just for about 100 sq. feet, and at whisper quite lowest setting I suppose it will will be able to purify air just a tiny 50 sq. feet area.
Back to the positives in design: it has several mechanisms for purification of air: permanent HEPA filter, UV light, and ionic filter. THere were reports that permanent HEPA filters are worse than replaceable, but for people who are not too sensitive to airborne contaminants permanent filter is adequate. It does remove some dust and it is cheap to operate. UV light kills bacteria and germs, and ionic filter is supposed to remove smells from the air. UV light and ionic filter can be turned on or off separately. The blue light at the top of the filter shows that UV lamp is working. The unit has a reasonable size which enables one to put it almost anywhere in a room. It is energy efficient: The UV lamp is 3 W, the fan consumes up to 55 W at its highest speed. The manufacturer recommends that UV light be replaced once every year, HEPA filter is permanent and requires only occasional vacuuming.
Returning back to negatives: it is built of cheap stinky plastic. When you turn it on, the room quickly fills with chemical smell. Initially I thought it was ozone from the UV lamp, but later it turned out that it smells almost the same even when it is turned off. It is enough to get close to the unit and smell anywhere around its plastic parts to figure out the source of the smell. My wife says she can't seat within 5 feet of it because of its smell even when it is switched off. Even a week after it was unpacked the smell does not seem to be getting weaker. Our whole family was getting headaches from the pastic smell when it was operating. Ionic filter was of no help, which makes one think that is is not efficient at all.
AS it turned out that negative factors by far outweigh the positives, I ended up returning it to the store.
Five stars for the design, zero for performance. Beautiful junk.
It is interesting that Costco removed this unit from their web site a week after I got it.

Box is deceptive, doesn't mention the UV light has to be replaced after a year of continuous use. Otherwise, it seems to be working for me so far.
