Side by Side Comparison of: Kaz vs Honeywell

My daughter has asthma, which we finally figured out is triggered at night by airborne allergies. She would get congested and have breathing problems at night, often needing her emergency inhaler without much relief. Once she got this air purifier in her bedroom and started running it every night on Turbo, her nighttime asthma attacks went away! This is worth it's weight in gold for her. I would highly recommend trying it if you or someone you love has nighttime asthma issues related to dust, ragweed, or other airborne allergies.

We purchased two of these for a larger area (open concept kitchen/dining/living room). We also have two cats and a golden lab and my wife has allergies. Our previous air filters both died after about 10 years.Noise lever is a huge issue for me as I work around fans and equipment all day long. These were selected based on Consumer Reports ratings along with customer reviews on CR and Amazon. We've had them running for two months now and we love them.We ran them on Turbo the first few nights and they are loud. As in no conversation in the room loud. But....the 'germ' mode (low) is fantastic. We can have them both running and they are barely noticeable as far noise level. Our running mode is to put them on 'High' (not Turbo) at night and then either off or 'germ'/low during the day.With the pets, a lot of grandkids that vist, semi-rural property, and wood stove heat, we have a lot of dust, pollen, and animal hair. When you purchase a filter pack, it comes with four pre-filters and three HEPA filters (the unit requires three individual filters). These are roughly projected as needing to be changed every three months and one year respectively. Based on what I see so far I think we'll probably get 2 months for the pre-filters and 9 months for the HEPA filters. I consider that pretty darned good.10/10 would buy again.

Pros:Quiet- whisperEasy to useLight can be dimmedVery pretty (aesthetics)Easy to put together (just unwrap filters and turn on)Light weightCons- none really- great product true heap filter- very inexpensive. You can set it for up to 8 hours on three different levels of filtration. I wish it was up to 12 hours, but it's made a huge difference in my apartment and it's so quiet I love it. The dimmer on the light which can barely be seen to begin with is an added bonus.

My chronic allergies and sinusitis have required that I use HEPA air filters in every room of my home. Over the past 20 years I have owned many different units, almost all of them were manufactured by Honeywell. While all had the same basic functions and worked quite well, this unit is by far the best and quietest air filter that I have ever owned. Consumer Reports rates this air filter very high and with good reason, because it's the best and most affordable unit on the market to date. The unit is very simple and offers double filtration, the extra thick charcoal filter is first, followed by the extra thick HEPA filter. The air is pulled in from the front of the unit where it goes through both filters and then comes out from an air grate on the top of the unit just behind the controls. This makes it a great space saver that can be placed almost anywhere, especially against a wall. There are 4 levels of filtration, #1) GERM, #2) GENERAL CLEAN #3) ALLERGEN and #4) TURBO.The 1st level GERM is virtually silent, I've never owned an air filter that is this quiet - it is the perfect level to use while watching a movie. #2) is a pleasant white noise that is barely audible and offers a great amount of filtration. The 3rd and 4th levels offer superior air flow and are so much quieter than my other Honeywell filters. While I still own multiple Honeywell filters and use them daily throughout my home, I will be replacing them with this unit as my budget allows. In searching for this air filter I looked very closely at comparable units priced as high as $600.- I was searching for an air filter that offered great filtration, but was also quiet so I could use it daily in my home theater room. After looking at almost 20 different units and brands in the $200-$600 price range, checking Consumer Reports as well as the Amazon consumer feedback I was won over by this Honeywell unit because of the price, the basic method of filtration, the very cool control panel, the fact that I could place the unit against a wall, the convenient size of the unit, and finally my positive experience over the past 20 years with Honeywell products. In the end I am very pleased with my purchase and would highly recommend this unit. One final note, the ability to turn the blue light off on the control panel is a welcome upgrade over my other Honeywell units. Thank you Honeywell & Amazon!

I have serious allergies. Spend a lot of time in my 14 x 20 office and of late had started to get serious allergic reaction - possibly due to my two cats and three dogs. This is a monstrous HEPA Filter. I have it on my desk right next to a couple computers and it circulates the air just fine. I can feel the difference. When I spend a good saturday morning or pull an all-nighter in the office, I dont have the same symptoms anymore. I have also begun to keep my office door closed to keep the cats and dogs out of late, but again - I've tried that before as well. This is a great unit which has a full-size carbon filter and three air filters that encompass the entire front of the unit. It blows air out of the top. So far, I have no complaints. I might get a couple for the living rooms as the built in air-conditioning filter can only go so far. I did purchase an extra carbon filter and a 3pk filter set which I'm told need to be replaced every 6 months. Will know more this winter. Not the quietest if you are running it in turbo mode or in allergen mode. But it has 4 modes in total and the first or second will suffice if you want to run it all the time.

HUGE problem buying correct filters. I ordered the filters they said I was suppose to order. This machine takes 3 hepa filters- I only got 2, type R This forces you to buy 2 boxes -total $80.. They did NOT last a year. Mine only lasted 3 months. $$$$.This is a keeper. I have tried several clean air purifiers. I expected to have noise as you would with any machine, but the Large Round Honeywell Pure Hepa sounded like a jet engine. I couldn't turn it on high- really loud. Why have anything if I couldn't use to it's highest capability? This machine is quite & great.I wanted to stick with a well known brand that had filters at a good price. I bought the Honeywell 300 through Amazon. The description says it covers 465 sq ft.. It does keep the air fresh and less dust in my 750 sq ft great room- it just takes a little longer to circulate the air. Some clean air machines must be put 2-3 feet away from a wall. This Honeywell can be placed against the wall. This was a huge plus for me, because of space. I am very happy with the Honeywell 300. No more sinus, watery eyes ,or other problems and much less dust. I can barely hear it on low, medium still has a low sound. (especially compared to the big round Honeywell jet engine). Turbo is the loudest and puts out the most air. Be aware the Honeywell goes by two different names: the Honeywell 300 and The Honeywell Allergen....same machine, two names! They have the same model and ISBN number. The Honeywell 300 is my keeper. Prime/Amazon. NOTE: Another company sells this Honeywell on Amazon, same machine, different name. I wanted to make my purchase through Amazon.UPDATE: 5/13/15. The filters do did not last one year. I need the 3 heap filters. I am having a problem finding the real Honeywell filters (not the cheap "knock-off" brands". I ordered more filters, but it says only 2 come in the pack. This machine takes 3 filters. I should get these within 24 hours. I will up-date then & we will see if they are the thinner cheap filters and if I get all 3 filters required. Still, it did work great -till now.Update: I should have updated this sooner. No more problem finding the 3 filters in one box. The new real Honeywell filters are great. I got all three- exactly as I needed. Very happy with this machine.

Pros:Easy to set upNot too loud. Sounds like a small fan is on in the room. I like white noise like that.Circulates air efficiently.Filters air very well.Cons:Expensive air filters (only reason why I took 1 star off the total)Other Comments:The biggest thing I was looking for in an air filter is how much space it would cover. I have a 20'x20' living room with 9' ceilings connected to a kitchen roughly the same size. This keeps the entire 1500 square feet of my upstairs clean.I ran it downstairs where I am doing demolition and BOY does it clean the air up fast when I have it on Turbo. Left it on overnight and it worked like a charm. I can already see the layers of dust in the carbon filter.Sound wise in correspondence with fan speed:Low ( They call it the "Germ" setting ) - sounds like an average fan on lowMedium ( They call it "General Clean" setting) - sounds like a fan on mediumHigh (They call it "Allergen" setting) - starting to get a little loud. Definitely cannot watch a movie in the same room with it onTurbo (They call it "TURBO") - What? What did you say? Oh God! It's sucking everything in!

It seems like they are working but I wanted to wait a little bit more to see if I can tell. But my son says that his little one for his room - which is the same Honeywell but the smaller version on it.The only thing that I don't like is it is so loud.You have to keep it on this high if you have allergies. The rest of the settings are for general cleaning. There are 3 settings and if your using it like I have to then your using the highest setting which is loud.The replacement filters are very expensive also.I did ask out allergist about hepa air purifiers and she stated that you don't need to spend over $100.00 for an air purifier as they should do the same thing and work the same way but just make sure you get on that has a hepa in it.

Filters air quickly and effectively. Filer replacement cost is expensive, but expect to only change filters one time a year. A true HEPA system, that creates a noticeable difference in any room it is placed. Extremely quiet operation on lowest setting, Turbo mode is fast and effective for air cleaning, with a bit more noise than desirable. Dimmer setting is greatly appreciated for light elimination. Easy to understand and use controls allow operation even in the dark with little effort.

The Honeywell True HEPA Allergen Remover met my expectations. People have complained about the front panel falling off. I have moved this purifier throughout my whole house several times a day in order to purify the whole house. 98% of the time. It never comes off. When it does, all I do is push the little two buttons and is back in place. Over the last month and a half I have ran the unit for between four and 12 hours a day. The filters appeared to be collecting dirt, dust, and are living up to expectations. I live in a forced air furnace house so dust is constantly blown around the house. The unit has reduced the amount. Once I turned my forced air furnace in the next two weeks. The real test will be do I see any dust in the air. The fan on the unit is somewhat loud on turbo. On the lowest setting, it is quieter than my furnace. It will be interesting this summer to use the unit along with my central air-conditioning. I'm expecting it to complement the air conditioner in moving the air throughout the house and house actually been cooler and more comfortable and cheaper to cool than in prior years. That test is still to come.

This item was exactly what I wanted. I am tempted to buy a second unit in the future for my lower level. I am not a big fan of switching the filters so often, but that is something i can get used to. I wish the different functions had separate buttons for because the unit seems big enough to accommodate this--however it is alright. My most favorite option is the timer. I have an older and smaller Honeywell HEPA and It is wonderful when you do not want to remember to turn it off at a later time or only want it on for a short period of time. My boyfriend and I who are both allergic to our pets agree that we started feeling better about air quality quickly. I also did not have a bad odor issue that some people previously mentioned. The noise is pretty loud, but if it gets the job done, I am not complaining! It also becomes white-noise after you train yourself to think "oh it's just the machine".

Seems to capture a lot of dust. Photo ofFirst filter with cover open

Only issue I have is now that I went to product tag to make sure I buy the right replacement filter I see HPA200...Fool me once...Paid for 300...seems for 2 months its been a 200 all along. Im sure was just a packaging mistake in China but...double check what data plate says (do not trust the box or just by looks).

nice machine, works well. The front cover sucks, for the price Honeywell should be ashamed of their engineering people. The cover falls off all of the time, I now have tape on a brand new machine. Would have given 5+ stars if the cover was worth a darn.

Work well ,but the replacement filters are $30 a piece. Not cheap, one of the units I bought has 3 filters. Fan noise on high for the allergen feature is loud.

The door is very loose, My filter buttons don't work at all. The timer buttons barely work. I didn't notice this until I needed to use those specific functions. It has cleared the air in our home as we live in a 2 story house, and my upstairs neighbors all smoke. It seeps through the vents and walls and I am allergic. Doesn't completely eliminate it but it does a thorough job. Foods that have a potent smell? Same. It does an ok job doesn't completely clear it up.

I needed a second air purifier, and was deciding between buying another Whispure 510 and buying the Honeywell. I have some buyers remorse because Honeywell does NOT sell pre-cut pre-filters. In an effort to save money, Honeywell created a "universal" pre filter that you have to fit and trim yourself. Maybe not a big deal for many people, but it's an annoyance for me.There is one Amazon seller that has pre-cut pre-filters, but they're pricey.If I had to do this over again, I'd buy another Whispure.

Though it removed most large floating carpet fiber, it still hasn't removed the smaller fibers floating in the air.It is a bit noisy in allergen or turbo mode. Could see the air being pulled in to the filter using the flash light during night time.However, also see the outcoming air still has carpet fibers. Though it has three regular + one odor filter (which need to be changed every 3 months or less depending upon usage) it still doesn't filter 1mm long Carpet fiber dust floating in the air. It doesn't have static filter to attract such floating allergens and no UVA features. Like the touch sensitive simple interface.

Despite the glowing recommendation from Consumer Reports, this unit is very loud. And not just white noise loud. There's a particular high pitched whine that I can only describe as being analogous to coil whine in electronics. Unlike white noise (which I personally find soothing), the high pitched noise emitted by the Honeywell purifier is intermittent, which makes it very distracting, especially if you are sensitive to noise or just have good hearing. I could hear the purifier whine all the way in my kitchen which is at the opposite side of my two bedroom apartment of 750 sq. feet. This was only on the medium setting. High and Turbo settings don't really change the high pitched whine, they only increase the sound of the fan, which is the regular white noise we're all familiar with. That being said, High and Turbo are loud enough that sleeping in the same room as the air purifier would prove to be challenging to most.The other downside is the number of filters. This purifier uses 3 HEPA filters, each of which is quite expensive. While you can opt for a filter pack on Amazon as an option, the pack only contains two filters, leaving you to source a third or buy another two pack.Lastly, the construction itself leaves a lot to be desired. Rough plastic molding marks are visible all over and the front cover is very fragile and can be removed inadvertently with even the slightest pressure.Probably the sole positive of this air purifier is that it does not produce ozone. Ozone is a lung irritant and can be poisonous in (very) large quantities. Ionizers are found on most air purifiers today and help to neutralize smells, but can irritate the lungs of people with asthma who might be purchasing an air purifier with the exact opposite intention. Still, I don't think the absence of a feature, good or bad, make up for the other issues plaguing this air purifier.

Really loud...can't sleep with it on the allergy setting...which is why I purchased it.

The 300 sq feet version is great however this larger version was just too loud. It emitted a high pitched mechanical noise.Returned this for the Whirlpool Whispure 510 which has been perfect.

Doesn't seem to be helping with our allergies. It is too loud to run all the time for allergy control, and although it picks up a lot of stuff in the prefilter we don't feel any relief when using it at lowest speed 24/7. Planning to buy an ALEN from the ALEN direct web site. Cannot return this one because over 60 days old. Should have read the return policy closer.

This HEPA device does work but the housing is poorly made. The parts do not fit together properly. The replacement pre-filters are expensive and cheaply made. You have to cut them to size. They are worth a tenth of the price paid. This is a case of a good product design that so cheaply manufactured it is not worth the purchase price.

the sound is too loud. The latch is crap. the rest works so far. But for the price i expected a better fabricated product.

I bought this item bc my neighbors smoke alot and the smells were seeping into my apartment. The product is lightweight and thats abt the only good thing I can say abt it. There are 3 filters and one carbon pre filter which are expensive IMO to replace. It is a little loud on the highest setting but i wouldn't have minded all of this if it actually did what i needed it to. The plastic was taken off the filters etc. and the sq. footage that it covered was sufficient. After leaving it on all day I would come home to the same smokey smell so i felt like it was a waste of money to keep. I had high hopes for this air purifier but it didn't work for me. Still looking!

45 days old and starting to sound like an outboard motor--I expected a lot better for the price and from Honeywell.

This product is supposed to be for people with allergies. Yet its overpowering plastic smell was so strong after running for an hour, we had to take it outside the house. It caused nose and throat irritation, burning eyes and a severe headache. Amazon gave us credit for its return - thank you Amazon. The Honeywell 62500 we were replacing never had this problem. Although it is over 10 years old, we replaced its Hepa filter and will continue using it instead.

Thought the room would smell fresher, it's run non-stop since the day I turned it on.

This product stopped working after just 2 months. For warranty work, I will have to pay for shipping the 21# air purifier + pay $10 for its return shipping. It was great when it was working but is now a piece of junk.
