It's probably no surprise that after the Alen T300 gained such intense popularity with households and consumers, almost all air purifier manufacturers rushed to put a tower design together to grab back a bit of the market share.

Today, we'll be looking at Honeywell's attempt. Is the Honeywell HEPA Tower Air Purifier able to surpass the performance of the T300, or does it fall short?

Honeywell HEPA Tower Air Purifier Specifications & Features

Honeywell HEPA-Type Tower Air Purifier with UV Germ Reduction and Permanent Filter 1 ea List Price: $249.99 Sale Price: $206.20 You save: $43.79 (18%) Availability: Usually ships in 1-2 business days   Eligible for free shipping! 26 new from $206.20

Filtration Functions
Unlike the T300 which only has a HEPA filtration device, the Honeywell HEPA Tower Air Purifier takes things one step further and adds a powerful UV light to the mix, which immediately kills any living particles (such as bacteria, mold, dust mites, etc) which might have been floating around your house.

The exceptional thing about the Honeywell HEPA Tower is that there are no compromises on the HEPA filtration units or the pre-filter, to accommodate this extra feature. The only major visible different is that the machine is slightly wider than the competitor, and resembles more of a squashed face design, rather than a cylindrical one.

Design & Style
As mentioned above, the Honeywell HEPA Tower Air Purifier is not cylindrical. In some ways, the design which has ultimately been decided upon is actually better than a purely cylindrical

Accreditations
The Honeywell HEPA Tower Air Purifier has an HHT rating of 145, which qualifies it very well indeed for use in small and medium sized rooms. The HEPA filter on board is of true status, meaning that it does actually provide the level of protection stated on the box (99.97% of airborne particle elimination).

Effectiveness
This air purifier is arguably even more productive than the T300, as it includes the renowned UV lamp technology to power its way through living organisms which may be unfortunate enough to get sucked in through the air intake (99.97% of such creatures are unfortunate enough every 20 minutes).

Air quality tests back up the claims made by the manufacturer - and as such, this is one of the best air purifiers currently available on the market.

Our Rating of Honeywell HEPA Tower Air Purifier
Anything less than 5 stars for the Honeywell HEPA Tower Air Purifier would be downright unfair. This air purifier provides everything you could possibly want and need to turn your inside air in to a fresh, biologically clean substance, which is very easy on the lungs.

Let's take this opportunity to inspect the Honeywell 18155 SilentComfort Air Purifier inside and out, to see whether you should consider this as a top selection for your next home air purifier.

Honeywell 18155 SilentComfort Air Purifier Specifications & Features

Honeywell 18155 SilentComfort Permanent, True HEPA Air Purifier List Price: $199.99 Sale Price: $129.95 You save: $70.04 (35%) Availability: Usually ships in 1-2 business days   Eligible for free shipping! 31 new from $129.95  6 used from $119.69

Filtration Functions
The Honeywell 18155 SilentComfort Air Purifier essentially has two filtration stages built in. The first is a HEPA filter, and the second is a carbon filter.

The HEPA filter works by trapping extremely fine particles, such as dead skin, dust mite excrement, and pollen. This is achieves by the micro fibers which are used to construct the HEPA filter. These fibres essentially impede the thoroughfare of tiny particles, and permanently stop them from passing through the stage of the machine.

The second filter - the carbon screen, presents a sticky surface which all air must pass over. Remaining particles which were missed by the HEPA filter - such as smoke and chemical residue, stick to this filter, and therefore cannot pass.

Design & Style
We've had varying feedback on the design of the Honeywell 18155 SilentComfort Air Purifier. Some people thought it looked like a clothes rack, whilst others thought it resembled a juice maker. One person even thought it looked like a pool cleaner!

Despite what you may think, it's really the performance of the product which counts, as this machine is small enough to hide away in the corner, or behind the couch.

Accreditations
The HEPA filter on board the Honeywell 18155 SilentComfort Air Purifier is so well designed, that it never needs to be replaced. A simple vacuum of the filter twice a year is all that is required to keep this device in pristine condition.

Effectiveness
The manufacturer states that this air purifier works in areas which are up to 197 square feet in size. Our test room was 240 square feet, which is well over the recommended maximum. We soon found, however, that the air quality analysis on this larger room was exceptional once we turned the machine on.

For that reason, we would go as far as saying that this air purifier can be used in any small to medium sized room with success.

Our Rating of Honeywell 18155 SilentComfort Air Purifier
Overall, we are proud to award the Honeywell 18155 SilentComfort Air Purifier a 4.5 star rating. This is a decent machine with a good mix of filtration stages (a UV step would have been nice), and a decent air quality profile to back up the results.

This product, with a recommended retail price of just over $200, represents excellent value for money on the surface. But when put to the test, will the performance live up to the high expectations that we already have? Let's find out.

Honeywell HFD-130 Germicidal Air Purifier Specifications & Features

Honeywell HFD-130 Germicidal Tower Air Purifier with Permanent IFD Filter List Price: $219.99 Sale Price: $149.95 You save: $70.04 (32%) Availability: Usually ships in 1-2 business days   Eligible for free shipping! 4 new from $149.95  1 used from $85.00

Filtration Functions
The Honeywell HFD-130 Germicidal Air Purifier utilizes state of the art HEPA and IFD filtration stages, to trap harmful molecules which are freely traveling around in the air. When you breathe these particles in, they can manifest in to things such as allergies, asthma, and eczema for an unfortunate proportion of people.

There is also an on board ionizer on this product, which means that the air will not only be cleaner, it will feel and smell cleaner too.

Design & Style
As we initially stated, the design of the Honeywell HFD-130 Germicidal Air Purifier is very futuristic. It could almost pass for a mini space ship - and your guests will be sure to comment or question what that "interesting" device in the corner is.

Thankfully, Honeywell (the manufacturer) has chosen to use a color scheme which is very pleasant on the senses with this model. There is a brushed silver, curved front, with a black bar and grill at the top and side.

Accreditations
Despite the price of the Honeywell HFD-130 Germicidal Air Purifier, this model has won numerous awards for its performance and efficiency. It has been awarded the energy star rating, as it consumes just 60 watts of energy. There is also a 12 hour timer on the device - which is useful for saving power during the day when no one is home.

Effectiveness
With three power settings on the Honeywell HFD-130 Germicidal Air Purifier - low, medium, and high (not surprisingly) - the machine is able to purify a room which is approximately 200 square feet in size.

In our independent air quality tests, we found that the effectiveness of the machine was second to none - and were impressed by the performance of the HEPA and IFD filters.

Our Rating of Honeywell HFD-130 Germicidal Air Purifier
When summing up the Honeywell HFD-130 Germicidal Air Purifier in terms of filtration, design, and effectiveness - we agreed that nothing less than 5 stars should be awarded to this product. This is an exceptional home appliance, and we were pleased to be able to test it out for ourselves. Home buyers will no doubt be extremely impressed with this machine, and we would highly recommend it to anyone with a need for cleaner home air.

Traditionally, Honeywell have used highly sophisticated technology to rid the air of any nasty particles which may have been floating around. This however, comes at the negligence of style and design in many cases. So - when we ordered the Honeywell HHT-090 Permanent HEPA Air Purifier, we were keen to see whether or not the design department had woken up from their dream state yet, or whether they were still pushing out more "ugly" prototypes.

Honeywell HHT-090 Permanent HEPA Air Purifier Specifications & Features

Honeywell HHT-090 Permanent Hepa Filter Tower Air Purifier List Price: $123.99

Filtration Functions
The Honeywell HHT-090 Permanent HEPA Air Purifier contains a washable HEPA filter - and this is the only source of direct filtration which is employed by the machine. This is to be expected however, because of the design features we will talk about in the next section.

Additionally, this model sports an ionizer - which is a post-filter device capable of charging the remaining particles in the air so that they become sticky. Of course, you won't notice any change in the air quality, but dust particles which were too small for the HEPA filter will stick to anything they come in to contact with - effectively indirectly eliminating them from the air.

Design & Style
This model from Honeywell takes on a "tower" design, whereby air is sucked in one side of the tower and pushed through the machine - eventually coming out the other side. The tower itself is very compact - and there is only one color option here, which is black. This means that the Honeywell HHT-090 Permanent HEPA Air Purifier can basically be placed anywhere you like, as black is the most neutral color to mold in with the surroundings.

Accreditations
Because of the lack of advanced stages of filtration on this machine, there is only one accreditation associated with the Honeywell HHT-090 Permanent HEPA Air Purifier. That is the true HEPA filter guarantee - which provides reassurance that the filtration quality does meet the standards of HEPA filtering.

Effectiveness
The recommended room size for the Honeywell HHT-090 Permanent HEPA Air Purifier is 169 square foot - significantly less than many other home air purifiers. There are a number of reasons for this. Firstly, the design is extremely compact and quiet - meaning that it can only process a certain volume of air at one time.

Operating in the pre-determined 169 square foot room, the air will be completely recycled 5 times every hour - which is an excellent rate. Expanding the size of the room obviously slows down this cyclic ability.

Our Rating of Honeywell HHT-090 Permanent HEPA Air Purifier
There is no denying the fact that the Honeywell HHT-090 Permanent HEPA Air Purifier is an excellent air filtration device for a home setting - but it does fall short of an all inclusive air purifier. For the price, which is currently under $200, we can't help but think that consumers are able to score an incredible bargain when buying this product. Overall, 4 stars from us.

This often results in a "draught" feeling, and in many cases, some air in the room never gets cleaned and recycled (called the "air stagnation" effect). Thankfully, the Honeywell 50200 True HEPA Air Purifier is able to solve this problem, as it is a true 360 degree air purifier, sucking air in from all around. This will come as great relief to those who simply haven't been able to get their hands on a decent, comprehensive air purifier.

Honeywell 50200 True HEPA Air Purifier Specifications & Features

Filtration Functions
This is an incredibly compact machine for its ability. The first thing you will notice however is that there is only one type of filtration mechanism inside - the HEPA cell filter. Whilst this is able to suck 99.97% of the matter out of the air, it isn't very effective for tiny bacterium, spores, or other airborne particles which are ultimately less than 0.3 microns in size.

For the price though, you'll be getting an absolute bargain. We have never seen true HEPA filtration (let alone in a standalone home air purifier) at this price before.

Design & Style
If you haven't seen a picture of the Honeywell 50200 True HEPA Air Purifier yet, think of a lettuce shaker. Remember those things we have in our kitchens to get all the water off the lettuce leaves? That's exactly what the Honeywell 50200 True HEPA Air Purifier looks like!

Plain white and relatively light, the Honeywell 50200 is able to be transported between rooms as necessary with absolute ease.

Accreditations
The filters on the Honeywell 50200 True HEPA Air Purifier meet the standard for True HEPA technology. Additionally, there are patents in place for the 360 degree air intake mechanism - which is such a valuable technological addition to this product.

Effectiveness
In our test setting, we let off various airborne particles in a controlled fashion - in an attempt to mimic the quality of indoor air in an average house. These particles included cigarette smoke, animal dander, dust mite excrement, and mold spores. We measured the quality of the air before and after the Honeywell 50200 True HEPA Air Purifier was turned on, to find out whether or not it was effective.

Our test concluded that the 99.97% claim was very close to being accurate, with our measurements calculating that 99.94% of everything we released was indeed picked up by the machine. Not a bad effort - and definitely worthy of a pass mark.

Our Rating of Honeywell 50200 True HEPA Air Purifier
Overall, we are happy to give this model a 5 star rating, due to its ability to significantly reduce the number or irritants and allergens in the air at any one time. This is an excellent product, and owners will undoubtedly notice a difference from the moment the machine is switched on.

But aside from the looks, it there anything else worth jumping up and down for on the Quiet Clear air purifier? We put the machine to the test, and have the results to show you exactly what we think.

Honeywell Quiet Clean Air Purifier Specifications & Features

Honeywell HFD-110 QuietClean Tower Air Purifier with Permanent Filter List Price: $169.99 Sale Price: $142.03 You save: $27.96 (16%) Availability: Usually ships in 24 hours   Eligible for free shipping! 31 new from $142.03  1 used from $99.95

Filtration Functions
Typically, tower design air purifiers are only able to shoot air through one filtration plate (due to the size). This is certainly not the case for the Honeywell Quiet Clean Air Purifier though. Incredibly, whilst maintaining the compact design, the manufacturer has succeeded in incorporating both HEPA technology and a UV light filter in to the same device.

This means that the bacteria, mold, fungi, and toxic spores which are floating around in the air - but too small for the HEPA filter to pick up on - will be instantly killed as they pass the UV filter. This really is a case of true design genius.

Design & Style
The Honeywell Quiet Clean Air Purifier has been designed to be extremely user friendly. An easy to use and intuitive interface at the top of the tower immediately lets the owner know what mode the air purifier is in, how much air is being processed, and what speed the far is on.

There is also a programmable timer on the machine - allowing it to be automatically turned on and off at different times during the day. Furthermore, the motors are padded with special "anti-noise" material, so the machine is exceptionally quiet.

Accreditations
These days, energy consumption is becoming a major focus of households, as they battle with the power companies to save as much money on energy as is physically possible. Leaving this machine on 24 hours a day will not hit you in the pocket as much as many other home air purifier products will, as the energy efficiency has been a major focus for the Honeywell engineers.

The UV bulb for example uses only 75watts when it is turned on.

Effectiveness
In a 200 square foot room, the Honeywell Quiet Clean Air Purifier is able to process all of the air at a rate of 5 times per hour. This means that if the product is left on all day, there is absolutely no chance that any airborne particles will survive longer than about 30 minutes (or 2.5 cycles). This makes for an exceptionally clean environment.

Our Rating of Honeywell Quiet Clean Air Purifier
After comprehensively reviewing the abilities of the Honeywell Quiet Clean Air Purifier - we are confident that the machine deserves a 5 star rating. Whilst it's certainly not the bee's knees when it comes to home air purifiers, the price and the size both combine with the performance to make this an incredible model. We have always enjoyed the efficiency of Honeywell products, and continue to see this as a major draw card for the company.

The Honeywell 11520 Envirocare purifier is small, lightweight, and yet packs a huge punch when it comes to on board features and technology. In this review, we'll put the Honeywell 11520 Envirocare Air Purifier to the test, to see how it performs under a number of common household situations.

Honeywell 11520 Envirocare Air Purifier Specifications & Features

Honeywell11520 Envirocare Portable HEPA AirCleaner, White List Price: $109.99

Filtration Functions
The Honeywell 11520 Envirocare has an on board HEPA filter, which provides true HEPA filtration technology. This particular air purifier has a number of other micro filtration devices on board - which clearly differentiate it from other smaller air purifiers on the market. The thing to keep in mind is the CADR rating - which is 160 for this model.

A small amount of research will show you that 160 is an extremely good Clean Air Delivery Rate, and that these additional "secret" alterations to the insides of the machine are definitely playing their part.

Design & Style
We weren't kidding when we said it was small. Weighing less than 17 pounds, this machine will fit almost any spot you pick out for it. Additionally, the machine is quiet, meaning that you can place it in a baby's room, or in the bedroom - even when you are asleep.

Accreditations
Amazingly, the Honeywell 11520 Envirocare is the number one choice for GP's offices and general physician's rooms in America. This is clearly because of its non-intrusive design, and the ability that it has to remove harmful viruses and bacteria from the air.

In addition, the CADR (which stands for Clean Air Delivery Rate) rating is 160 - which is a truly excellent score, and at the top of the industry average.

Effectiveness
The recommended maximum room size for the Honeywell 11520 Envirocare Air Purifier is 12' by 16'. Assuming that you place the air purifier in this sized room, the air will cycle through the machine once every 10 minutes (i.e. a full air change in the room every 10 minutes). That's six times per hour. You can probably now understand why the machine is so popular in doctors' offices around America.

Our Rating of Honeywell 11520 Envirocare Air Purifier
Who would we be to argue with doctors throughout America? The fact of the matter is that indeed, this is an exceptional piece of machinery, and the Honeywell 11520 Envirocare Air Purifier really does deserve every one of the 5 stars that we will award to it.

If you are looking for a non-intrusive, effective air purifier, this is definitely one to put on your list of considerations.

If you answered yes to any of those questions, then the Honeywell HFD-120-Q is yours for the taking.

The Honeywell HFD 135 comes with a multi-stage air purifying and cleaning system. Whenever air comes in, you can be assured that it goes through different filters to get rid of different air impurities. And they work well even at filtering out particles that are as small as 0.3 micron. Dust, pollen, pet dander, and those not-so-friendly particles that are elusive to the eye won't escape the filters of Honeywell HFD-135!

The Honeywell HFD 135 is a highly recommended air purifier!

When it comes to filtration, this air purifying unit is a force to be reckoned with! Its HEPA filter offer 99.97% filtration. Not to mention it has 2 filters - the main filter (which is made of HEPA material) and a prefilter that takes care of other larger particles. That means your main filter will have a longer life than it would if its working all on its own. This is what attracted me to the Honeywell QuietCare 17000. It took me about 6 months before I needed to replace my air purifier's HEPA filter. And replacing it is made easier with the indicator that will tell you when it needs to have a new HEPA filter. No more guesswork!

As for the controls, I'm giving this air purifier another 2 thumbs up. It comes with soft touch buttons that don't make the usual clicking sound when pressed. This makes it an excellent choice for a child's room. You can easily sneak in and change the settings without waking up your little one.
