Surprisingly Effective
I got this at Target for a bargain price, and while I was initially skeptical, it has proven to be a great addition to my small apartment. I like sleeping with background noise, so the humming on the highest setting is better than the fan I was using before. The ultimate test, though, was getting rid of a 14-year-old's stinky foot odor out of my office. In the past, I've had to open all the windows and spray the room with Febreeze to get rid of the smell (and even then it would linger for quite a while). Now, I just pop this air purifier in, shut the door, wait maybe 15 minutes and the smell is gone! Thanks, Filtrete!

Works great on smoke
I got one...and was not sure whether I was going to use in bedroom or workshop. My spouse smokes in the shop so I put it out there. He turns it on when he smokes. The second hand smoke smell is gone. Air seems much clearer.
And the filter has changed colors. I think it works well, so I bought another for the bedroom. Also got a $[...] rebate. P.S. There was no smell when I first used it as another Amazon client noted.

It is a rather large unit and the filters are $[...] on sale. Supposed to change them every three months.


Update, bought second unit for the bedroom. Nice looking.

Best I've Found
In my opinion, there are few products we consumers are less qualified to judge than air purifiers. The word "seems" keeps coming up- it seems the air is cleaner; it seems that I can sleep better; etc. Really, if you see less dust, for example, does it really make an appreciable difference to your health? Even Consumer Reports, with all the science at their disposal, doesn't do a sample of the population over time to show that one air purifier keeps us healthier than another. I live in a very old, drafty house in Chicago. I was getting sinus infections regularly, and looking back realized they began after big rains or melting snow. An air quality expert determined the culprit was mold. I couldn't afford mold remediation, and he suggested an air purifier in the meantime. We don't have central air, so I needed more than one. I bought a CR-recommended Kenmore. Big and noisy, and blows cold air- not good during our winters, but it SEEMED to make a difference. Then I discovered the 3M Ultra Clean. I will try anything 3M- from tape to home remodelling products, their stuff works best. The Ultra Clean takes up less space, is much less noisy and circulates the air gently and thoroughly. Turning it on I had the immediate impression of "fresh air". I placed it in the TV room, where the mold is the worst and where we spend a lot of (too much!) time. We had lots of snow in Dec., then it got warm and lots of melting snow/rain. The moldy smell and "chokey" feeling is virtually gone. Try it, give it a week or two trial. It has an electronic monitor that tells you when to change the filter. My model, which looks different than the one in the manual (?), has this grapefruit-sized three speed selector knob on top, with swirling green lights (filter ok) that change to yellow (needs changing soon) then red (change the filter). (You might find the lights annoying in a darkened room.) Still green after two monts, but I'll assume it works. On the downside, the knob has a very uncertain feel and you have to play with it until it settles on a speeed. Maybe the model pictured in the manual is an upgrade. If it's a later model, you might want to try and find one of those.

Salvation
I have bad sinuses. I used to get the occasional headache from dust, but I had my last wisdom tooth pulled this year and have graduated to the next level. Here was my problem. I like to sleep in on weekends. If I slept in and had the air conditioner on constantly, life was good. If I turned the A/C off and overslept, I was in that useless sinus headache mode where functioning and concentration are not possible- it's more of a crappy state of consciousness than a hurting pain. I realized I needed an air purifier to make it through the winter. This has worked.

I researched alot of different filters, but what pulled me to this was

a. 3M product- good company that comes out with solid products.
b. Filter experience- 3M has been making furnace filters (which is basically what this is) for decades.
c. Nice looking unit- but if you are sinuses hurt you could care less.
d. Filters are $[...] @ Target

What I like about it since I bought it:

a. It's got a nice white noise to it. The white noise is similar to an air conditioner when on high- if you need super quiet put it on the low speed and most people won't hear it.
b. Absence of smell- this is weird. When you walk into the room there is a wierd 'no smell' smell kinda thing going on. It goes away in a few seconds.
c. It works- I can stay in bed on weekends.

Note: This unit hasn't been around that long compared to others on the market. I have had mine for 3 months and love the thing. Whatever you decide on getting can get very expensive. The heavy duty "Boy In The Bubble" models will cost you over $[...]/year to maintain for the European units- less for the American units. I recommend trying this first because it's cheap. If this doesn't work, then keep going up in $$$ til you hit the remedy. Also, before you try this, if you have central air/heat you should try changing your filters every 60-90 days with the best filtrete filters (which is what this is) and see if that works.

Works great, cheaper than the model with a remote
I purchased one of these from Target a few days ago because my apartment smelled like cigarettes from the smokers down the hall. Sure enough, the unit cleaned out the whole bedroom's smell and let me sleep much better overnight. A rather unexpected thing happened as well though. I had read someone else's feedback about an air purifier stopping their snoring. I didn't really think that could happen, but sure enough it did the same for me. Maybe there's some type of allergen in carpetted rooms that causes throat or sinus tissue inflammation or something... I don't know; but it works. I've also read that the filtrete filters used by 3M are not as effective as HEPA filters, and don't disinfect like an ozone-based purifiers, but this guy does the trick for me (and the filters are cheap). Overall, I'm quite happy with it. The funny little purple control knob on the top also grows on you.

Best unit ever
I've had many air filters and cleaners over the years, living in Los Angeles requires that. I miss the days of citrus-scented filters. Oh well. This filter unit, the Holmes HAP242 has been the best ever, and these filters are great.

A breath of fresh air
This is the right replacement for your Bionaire BAP242 Air Purifier, even for the UK model.

for two plus free shipping means it's cheaper here than in the UK.

Bionaire BAPF30
I got these filters for a Bionaire air purifier. Perhaps I should be reviewing the purifier and not the filters, but without them it doesn't work (and viceversa)... so I guess this is a co-review. I noticed a big difference in my son allergies after just 2 days of use. He is just 2 years old and has been sneezing since the day he was born: he gets a stuffy nose, sleeps with his mouth open which dries his throat and makes him cough. I had tried everything else to try to help him. I received the air purifier through a recycling group and decided to try it. I absolutely love it, so much that I'm getting another one. This 2 pack is the most convenient way to get them even if you just need one, because you will have the spare one in case you don't remember to order it on time to replace it. And the price is great: it saves around from buying a single pack and buying it in Amazon.com, you get free shipping.

Great $ value
Glad to find a needed item online that is not always available retail when you need it. Worked out great!

Money well spent
I have a bionaire air purifier which requires replacement filters about once every 4-6 months or so, so I try to look for package deals that contain many of these replacement filters for a less expensive price, and I was glad to have found them! There are 2 replacement filters in one box that's especially made for the filters, which would be very appropriate if you are giving them as a gift. Along with each replacement filter, there is a little bar clip-on thingies included (if you own one of these purifiers, you'll know what I am talking about), which tend to easily be lost if you are changing filters and not paying attention. But since they come with the replacement filters in the box, you have extra ones in case you ever accidentally throw them away! In all, it was a great deal and i bought 2 boxes! I am happy with my purchase, and the delivery was super fast!

Best Item packed in a smaller size
I purchased this product last month and it sure lived up to its hype. I use to see alot of dust flying around in my house. I'm glad to say now its disappeared. My house is more fresher and more alive now more than ever Thanks to the Ionic Pro Therapure 100 now i just keep it near my computer.

Don't Be Fooled! It is NOT an Ionizer, NO filters. Only UV.
First and foremost, don't be deceived! The simple fact that this was listed in the ionizers category is just plain WRONG! Look carefully and the only place you'll notice the word "ION" is in the company name. What a scam!

Long story short: For ten bucks less, grab this even-smaller unit (about 1/3rd the size of this unit) which does the same UV-only purification: http://www.amazon.com/gp/product/B000G2BESO?tag=a52-20&ie=UTF8

With that in mind, does this unit work? Yes and no.
We use it in the cat-duty room... you know, the room where cats do their duty! The room is very dusty and its smell tends to permeate into the surrounding rooms, one of which is the home office. Not good!

So we got this unit and set it up. It did indeed clear up the odor, for the most part, within 24 hours. Odors still lingered in the small room itself, but they no longer traveled into the other rooms nearby.

However, 3 days later, I started hearing a strange noise coming from the room where the purifier was installed. (I was on the other side of the house when I heard it, and the TV was on.) Upon investigating, I discovered that it was the purifier! The fan/motor (on the low speed, mind you) was vibrating so wildly you would have mistaken it for a Deisel Semi-Truck engine!!!

Figuring it just needed to be cleaned, I researched on how to do so. That's when I discovered that the thing wasn't even a real air purifier, moreso jist a glorified disinfectant! What an outrage!!

We decided to keep the unit anyway, since it does work, and have now had it a couple months. I constantly have to clean the fan with canned air, which re-disburses the dust all over the place. How annoying (and I'm a germaphobe...can't standing breathing when I do this, nor in the surrounding rooms afterwards, until the dust settles).

Despite constantly cleaning this thing, it still raves like a mad lunatic even right after being "cleaned". My wife even made a diaper for it: a home-made filter that she wrapped around the intake vents. We also put a custom-cut circular carbon+hepa filter on the inside to catch any more dust that might have escaped the "diaper" filter. Even so, it still gets dust in the fans and still sounds like a Mac Truck or like a noisy weedwacker on good days, and it goes in and out of its quiet mode. So it's noisy for a good 25-50% of the day, at least.

Lately we've been smacking the unit which seems to be a temporary fix, but the unit really does seem to be just junk. Hope you find one that works better!

Less efficiency
The product is too small to purify air for a small size room. So we had to buy a HEPA air purifier.

Fresh Air At Last!
This is a great air purifier! The uvc light bulb is huge compared to the one in the Germ Guardian GG1000 I have in my bedroom. Both work well. I got the ionic pro because I wanted an air purifier for the dining room and had no wall space for another GG1000. This is a student house and we have our windows closed and sealed for the winter meaning cooking and other smells linger and the air tends to get fusty. Not anymore! I have the fan set on medium with the unit on 24/7 and that is enough to keep the air clean and fresh. Another plus is that the light bulb is replaceable.

Only works one way
I ordered this on the basis of these other reviews thinking this would work for my allergies but after it came I realized that this is just a sanitizer utilizing a UV light. I should have read the product description more closely. To help with allergies, one needs a dust and pollen attractor. This little thing seems to run well otherwise, I suppose, although I have only the manufacturer's claims and no way of knowing if it is killing any germs! It's only about 14 in. high so is very nicely styled and compact.

Really noticeably works!
I bought this on the recommendation of my Doctor of Oriental Medicine, who owns one herself. She thought the wood smoke particulates in my home were bothering my respiratory system and she was right. This unit makes the air feel and smell fresh and clean and within a couple of days I was breathing better and had less respiratory issues bothering me. Well worth it. And small enough that I can move it from room to room easily (and I am 64). Highly recommended. It also came with a free filter, an additional value, which I thought was fabulous.

Quiet, Effective, Fantastic
This is a great air purifier for a single room. I have severe dust and mold allergies, and can now sleep in my old, dusty, moldy house without waking up because I can't breath. I have been running it 24/7 with no noticeable change to my power-bill.

No more coughing and clearing in the morning
This solved my daughters dust mite allergy problem. She had been waking up
every morning too early with minor but persistent coughing and throat clearing
that would start around 4:00 - 5:00 am, and continue so she was not able to
get back to sleep. Getting up and going would stop it until the next morning
when it woke her up again.

We cleaned her room thoroughly many times, but were about ready to replace the
(3 years new) carpet with hardwood in her room because we could not resolve
the problem. But this machine does the trick. Almost no coughing or clearing
anymore in the mornings before she gets out of bed. She slept until 7:00 today.

Any purifier may have fixed this, but this one did it for us so I'm very happy
with it. It was important for our needs that this one filters out very small particles.
It's also very quiet and the blue light acts like a night-lite for her (I would
tape over that if this were in any other bedroom). And it's simple to use: we
turn it on in the late afternoon (a simple dial switch that clicks into four
settings - off, low, med, high fan) and off in the morning.

Doesn't work as described
This item does not work as it claimed. it is very expensive, too. suggest you Winix brand, I had one of that kind too . The winix has a dust sensor and odor sense which automatically turbo the machine when it senses dust.

Blue Air 210B--great product
Got this for my wife allergies and don't know if it helps yet but this unit is the quietest I've heard and seems very nice. The 201 and the 210 are the same excepting the 210B comes with an extra filter

airfilter
this air filter works great for how small it is i have 7 cats and i put the filters in the to rooms with the litter boxes and it cleans the air really good

Great product for the money
The product is worth every dime. It works slowly but surely does get rid of all the odor. Even in a house where spicy food is cooked on a regular basis. The catridge effeciency starts going down after a month of regular usage

excellent!
I love this little air purifier and I love the seller!
These things work perfect for the spring with all the allergies floating around in the air. Sadly, Hamilton will not be producing any more of this model =(

A real piece of junk
Shortest time-to-garage-sale in our recent history. What a piece of junk. Works about as well as plugging in a hair dryer and blowing air around. A real ripoff.

The perfect white noise machine
I'm really sensitive to noise when I'm sleeping and have been relying on this machine for about five years. I use the "Quick Clean" feature because it's louder than the regular option. It drowns out noise and helps me sleep great. It finally died a few days ago, so I'm buying a new one. It actually didn't die, but it's making a really weird noise that's annoying, so I'm throwing it away. You can find a similar one at Target that's made by Febreze called "True Air," but the thing is whisper quiet and therefore completely useless to me.

Very Happy
I just purchased my second Hunter Air Purifier. I gave my old one which I had for about 5-6 years to my mother as I was moving out of state and thought it was a good time to upgrade. (The old one is still working perfectly and I can't believe how old it is!) My new one which is a little bit bigger than the old one has been working wonderfully for the last 3 weeks since it arrived. I've been running it almost continuously, 24 hours a day, and the filter is almost ready to be replaced! I moved from a relatively clean environment to a very polluted one and it has really made a difference. It is practically vacuuming the floors as I am finding bits of feathers and things that were in the carpet in the pre-filter. I'm sure after this initial clean up, the next filter will last a lot longer. (My old filters in my old environment always lasted more than 6 months) My boyfriend and I keep it in the bedroom (on high and with the ionizer on)and we really can tell the air is cleaner and we have been sleeping great. It is quiet (quieter than my old one) and has a soothing sound, yet the wind out of the top is powerful and circulates the air nicely. It's idiot proof to operate. I did a lot of research before purchasing and I don't think you can find a better machine in this price range.

It's working great!
I bought this purifier in order to help clean up my art studio's air. I usually get to feeling a bit off after being there for four hours or so. Now that I have the purifier right next to my workstation, I find I can work longer and with a clearer mind. I don't go home feeling ill anymore! (I'm a bit chemically sensitive and the windows don't open in the studio.) More good news, I only run it when I'm there, so I shouldn't have to replace the filters as quickly, but it still cleans the air well enough to help me stay healthy!

Yesterday I brought it home in an effort to help stymie the sinus migraine that my husband and I were getting after the rain. It worked fabulously and seemed to bring us back to life. We live in Texas and a lot of stuff grows after a storm. So, I expect we'll be buying a few more for the house.

Very happy with mine, give them a decent break-in period
I've read reviews here and on shopping network sites where people complain about the smell. That is a new product smell that dissipates within a day or two. However, the ionizer is what causes it, and it has an on/off switch. So if the smell bothers you don't use it! I have bad allergies and these have helped me tremendously. Also, when you're comparing prices with Amazon and other sites, pay attention to how many items you get. For example, someone stated the filters were really cheap here, but the price is for one, when the "more expensive" site was offering a two-pack.

Good solid product
I purchased this product because I suffer from severe allergies during the pollen season. I would have trouble breathing inside my house because the pollen level in GA reached in 4000s. After starting this purifier I noticed an almost immediate improvement in the air in my room. I definitely can breath much easier. Running it for over an hour in a closed room will totally clean the air and make the environment almost allergen free.

Wonderful Air Purifier but be Prepared for Filter Price Shock!
Absolutely wonderful filter that takes tons of crap out of the air with its double filtering system but Hunter definitely makes their money on the sale of filters and prefilters. Be sure to check the prices of filters for units and remember that they usually need to be changed 3 or 4 times per year. You will quickly find out that a year's worth of filters will cost more than the air purifier unit itself. Good unit though!

Cleans the air!
Does a great job at cleaning the air.
I have pet order and this takes care of the problem!

It's both air cleaner and pet Cylon
Yes, this air filter kinda looks like a Cylon from Battlestar Galactica. The glowing blue UV light is cool looking, especially in a dark room.

I like this filter because it works very well to clear the air and the filters are permanent (no replacement filters!) and said filters can be cleaned easily by the user (if you have a vacuum cleaner).

I can honestly say this filter has helped my allergies. Judging from how much gunk was on the filters when I cleaned them, I think I made a good purchase.

The fan has three speeds, so in the warmer months it makes a great fan as well as an air cleaner.

I think this filter is a bit more noisy than the company claims, at least on the higher fan speeds, but it's pretty quiet overall.

There is a timer you can set so the filter can turn itself off (after up to 18 hours) if you want to filter the air while you're out.

Overall, I'm very pleased I purchased this product (and I got a great deal on Amazon...even better than eBay...and even better than the deal I could have gotten from my friend's mom, who works for Honeywell).

Works Great!
When I bought this purifier, I don't think my husband, and therefore, myself, had slept through the night in over a month. He has asthma, allergies, and sinuses, and something in our house was giving him fits. We do have carpet, and we got it cleaned around the same time this came in, so I can't contribute the restful nights all to the purifier, but after the first night using it, we could definitely tell a difference. After a week... no more sleepless nights. It works great! It is loud on the high setting, but so is our air conditioner and heater, so it doesn't bother either one of us, but if you're worried about it, you can just put it on low or medium for the night. All in all, highly recommended. Great product for the price!

preschool teacher
I recently discovered that I have severe dust mite allergies. I found this on amazon and noticed good reviews so I purchased it. Everything everyone said about it is true. I notice less dust in the room, it feels cleaner somehow, and I wake up with less eye irritation. The only bummer is that it is fairly loud on the highest setting and it makes the room a little colder. If I could afford it though, I would purchase it for other rooms despite the noise and cold.

Great little workhorse
I owned the Honeywell 17000 for 10 years- since '99- and it finally broke a few months ago. It came reccomended by my allergist-- cost effective and good for a small space. It was a reliable, hard working unit-- I moved 5 times (+?) with it, abused it by not changing the outer filter as requently as it needed and have a cat! I decided to replace the unit with the 17005 as it's programmable with remote. So far, so good...

Yes the 17000 and 17005 create a white noise, air pushing sound, which I like anyway (kills noises for sleeping), but it's not deafening, and if it bothers you throw it in the corner of the room; it will cycle the air the same. I would disagree that it's as loud as an a/c-- those things roar!

Anyway, these two websites might help you make your decision, too.

Instant relief!!
This was such a simple fix to several problems, sinus pressure and difficulty sleeping, and feeling brainless and singing was pure torture. I was using many otc and herbal remedies to little success. What sleep I would get I would not awaken refreshed from. Sinuses would still be sore and I felt listless and thick headed.

Somehow I managed to think of how dirty the air is after 10 months of no rain and gave this unit a try. The first night alone aleviated much of the sinus pressure........then I could sleep better. I find the low setting no problem to sleep to, and I sleep light. After a few days I could sing easily, instead of trying to sing thru the concrete wall of my sinuses..when my voice would jump in my nose or crack in my throat as I had no control.

As I still have to work outside a few hours each day, I sometimes get a bit of sinus pressure so I use Sinus Buster when I feel that.

I wake up with EVERGY starting my outside chorse at 5:30 AM. Before I'd drag until 6-7. I knew it should help, but I had no idea how much.

Honeywell 17000 HEPA QuietCare Air Cleaner
This is the third Honeywell Hepa Air Cleaner that I have purchased. The first was at a regular retail store and the last two were here at Amazon. As a severe allergy and asthma sufferer, I need more than meds, filters on our house heating & air unit and other measures to contain my allergy outbreaks. I keep one of the Honeywell units in the masterbedroom, one in the den and the other is a "floater" for whichever area is needed. The filter is easy to change and I have not yet had to change any hepa filters (the oldest one is several years old!).

I definitely would recommend this product to anyone looking for an Air Cleaner. It does all that it promises and more.

Not as good as i hoped
I currently have a high end ionizer at home i use. that one takes out the orders that are left behind from the previous renter that had cats. so i thought why try one for my truck. I drive 45 minutes to work. Plenty of time i thought to see if this device really works.

pros:

1: if left overnight the next day i can smell the ozone in the car. but it quickly evaporates when the door is open to get in.
2: it took about 1-1/2 hour of constant use while driving to start to notice a difference.

cons:
1: when it worked it showed only minor improvements. i stopped using it because i did not want to wear down the battery leaving it on all the time.
2: i could not tell if it was my imagination or the device working.

conclusion:
personally i wish i would have saved the money and used it on a small air purifier with a 12 / 110 volt converter.. i think it would have help a lot more. a bit unconventional but strapped in the passenger seat i know it would have don't a better job that this had done.

Good Product
It seems to do the trick. I am a smoker and it really does remove the smoke smell from the car.

OK...wait, what?
Hmmmm...hard to tell if this really does anything after almost a year. But then, I do not smoke or own pets. Same amount of dust accumulates on the dash...

Works great
We purchased the Gaiam Auto Ionizer as we had purchased a used car that, while clean inside, held a musty odor. After trying to eliminate the odor with cleaners and air fresheners to no avail, we purchased and installed the Auto Ionizer. The Auto Ionizer ran without a sound and within the first few days we noticed an improvement. Within about two weeks the Auto Ionizer eliminated any trace of lingering odor - not masking it, but eliminating it. We are very pleased with our purchase.

Does not work
I do not feel any difference, there is just a light which is on!!!!!!! that's is the only thing I can get from being on!!!throwing money away
