Honeywell 18155 Air Purifier Review

The 18155 created by Honeywell is a cost-effective, yet middle power – HEPA particle filtration system. 18155s are from the 14-inch circular filtration system family of Honeywells.

What other consumers think?

PRICE = $129 (

Before we talk in depth about the 18155 purifier it is worth checking out what other consumers think of this air cleaner. Overall this purifier has relatively good reviews from other consumers with the majority of reviews coming from

Review Site Rating 4 Stars (99 reviews) 3.5 Stars (2 reviews) 3.5 Stars (2 reviews)
New Egg 3 Stars (3 user reviews)

CADR Rating: 150,150 and 135

Together with a clean air delivery rates (CADR) of a hundred and fifty airborne dirt and dust, a hundred and fifty smoke, 135 plant pollen, and a strong AHAM given of 230 sq . feet space score, we think this small Honeywell is a little bit over rated.

Consumer Reports

Consumer Reports ranked the 18155 as "reasonable" and "weak" for high-speed and lower speed dirt and cigarette smoke elimination, getting ranked 22 out of 30.

What Sized Room?

This particular air purifier is promoted as offering six air changes for each hr within an 11′ x 17′ space. That is 187 square. foot., below the 230 score awarded by AHAM throughout the CADR accreditation.

Space sizing rankings, according to constant high-speed functioning, certainly are a frustration for buyers. The purifiers are not generally silent enough to operate on high along with human activity, particularly sleeping, within the room.

I suggest the 18155 Honeywell for 144 square. foot. areas, a moderate 12 x 12 room, at the most.

Filter Change?

Brand new 18155s possess the "life time" HEPA glass fibre air filters promoted as practically never needing replacing. In any other case, they’re the same as the 18150. The brand new filters are durable enough to get recurrent vacuuming. A few customers state they experience having to replace these types of filters anyway.

Just like numerous reduced price HEPAs, Honeywell 18155s have got filter expense difficulties.The thirteen dollars to $15 pre-filters on it’s own, if adjusted each and every three months as suggested, equal to the first purchase cost of this air purifier in a little more than 24 months. Lifetime is really a filtration system slogan, not really a guarantee


The Honeywell 18155 is not a bad air purifier for the price of $129 but we would suggest the buyers look at spending a little bit more and purchase the Honeywell 50250 which provides more cleaning per $ spent. In the long-term the 50250 will work out cheaper and your house will be cleaner.

Honeywell HEPA 50250-N

This is a review of the Honeywell Enviracaire 50250-N Air purifier.

honeywell 50250 HEPA air purifier

Before we jump it to any specific details about the Honeywell 50250-N, lets first check out what score this purifier achieved on the major internet retailing websites:

Review Site Rating 4 Stars (188 reviews) 4 ½ Stars (16 reviews) 4 Stars (15 reviews) 4 Stars (52 reviews) 4.70 out of 5 (10 user reviews)

Overall, the 50250-N purifier has achieved favourable scores across all the major sites that allow consumer reviews. The next step we need to take is to dip a little deeper and find out what some of the experts think of about this particular air purifier:

1. Air Purifier Power – Written By Ed Sherbenou – URL


Air-Purifier-Power Rating: 80, good


  • Here’s what I find nice about Honeywell air purifier’s durable, basic style. It is made from solid, powerful plastic material, and also sealed closed with a bolt about half inch by 5 in.
  • Quite a few low-cost HEPA air purification products are made of numerous parts, along with splits and seams which leak.


  • Just what is not so great is the noises this Honeywell 50250 creates: it is fairly loud. 50250’s Sound spec is 35/45/57 decibels (A), however that appears understated.
  • Yet I hardly ever utilize it within the bed room, for it is a little loud for me to snooze with, even using the low setting.
  • Not fantastic for light sleepers.

2. URL


Owners and also specialists are usually fond of the Honeywell Enviracaire 50250-N air cleaner


The actual comprehensive agreement is that this particular model is acceptable for the cost that is charged.


First, this particular low-cost air cleaner is not designed for large rooms, and 2nd, it is extremely loud.

CADR Results:

Any CADR, is determined by The Association of Home Appliance Manufacturers, it informs all of us not just the amount of air which is purified, but additionally exactly how well it’s purified. Air purifiers which have been examined by AHAM must have the AHAM Qualified seal and also CADR figures for 3 contaminants: cigarette smoke, plant pollen, and airborne dirt and dust. The larger the CADR score, the more efficient the air cleaner is in opposition to that pollutant.

The Honeywell HEPA 50250-N scored: 250 CADR Ranking

Technology Used:


The Honeywell 50250-N utilizes HEPA technology and has an extremely large filter in comparison to the size and price of the unit. Ed, from air-purifier-power stated that he had seen 18 wheelers with smaller filters!  HEPA filters are able to remove 97.97% of particles bigger than 0.3 microns which removes most air borne dust, pollen and allergens.

This HEPA filters used are lifetime versions so you will be able to vacuum the filter rather than just throwing it away and replacing it. However, don’t expect this lifetime filter to last till your 80 as it still degrades over time.

NOTE! Watch out for the old 50250 without the N at the end. These older purifiers do not come with the lifetime HEPA filters and will require changing far more frequently.

Power Consumption

Air purifiers will often be required to be used for a large proportion of the day so energy costs both ecologically and economically should be taken into account. The 50250-N uses the following power settings:

  • Low = 50 Watts
  • Medium = 120 Watts
  • High = 170 Watts

Leaving this purifier on the high rating 24 hours a day will cost the same as leaving on two non-energy saving light bulbs

Addressing the Sound Problem

Many reviewers note that the 50250-N purifier is very loud on the highest setting. To give you an idea of how loud, we have put together a video + sounds that show the 50250 purifier running at its highest setting. Ed @ air-purifier-power states that he won’t use this purifier in his bedroom because of the sound.

Personally I think this purifier is too loud for my bedroom but would not be a problem in my kitchen or dining room area.


This is a solid purifier and is very good value for money. I personally would not recommend this purifier for usage in the bedroom (at night) but its a very cheap way to clean a small kitchen, dining area or any other small room.

It would not make economic sense to spend $900 on an IQair Healthpro plus for every room of your house – so i recommend using a the Honeywell 50250 in smaller rooms that require clean air. I give this purifier from Honeywell a 5 star rating and itnow  ranks at the top of my list for budget purifiers ($100-$200.)

Panasonic Air Purifier Review

Panasonic F-P15HU2 Air Purifier

The top selling Panasonic purifier from is the Panasonic FP20HU1 Air Purifier which sells for $140.

Panasonic FP20HU1 Air Purifier

The upgrade on the previous purifier is called the Panasonic F-P15HU2 which sells for $299

These Panasonic purifiers are clearly budget purifiers but it seems that they do a very good job for such a small price tag.

The FP20HU1 gets 4 stars from for 7 reviews and the FP20HU2 gets 5 stars for 7 reviews. Review by A Customer

The FP20HU1 purifier got one review that gave it only 1 star so its worth looking to see what this customer thought about the product: review

Worthless expensive Product and Horrible Customer Service”

I am always wary of really negative or super positive reviews.

“In addition,it will dry up your room and your eyes will get dried and even turn red. It did not work, when my room was dusty. I bought this because I was allergic to mite and dust but it did not work for me at all. I recommend Sharper Image Ionic Breeze, if you want better air quality.”

Now, I can’t see any reason why an air purifier would dry the air unless they had a dehumidifier function which this purifier lacks. This reviewer has many negative points and shows no positive aspects. Its very rare that we totally hate a product completely so i am already starting to disbelieve this product review.

Now when this reviewer mentions a particularly awful product – The Ionic Breeze, we should discount what this person says completely. This is a perfect example someone submitting false reviews to make people buy their product.

With this review discounted both Panasonic purifier score 5 stars which is impressive as Amazon customers can be very critical.

Clean Air Delivery

In the clean air delivery test the Panasonic F-P15HU2 was quoted as providing a CADR of 150 which is amazing considering the price of this unit.

Size of Room

Both purifier are capable of cleaning rooms up to the size 12 feet by 18 feet. So this purifier is for use in smaller rooms which is to be expected for a unit of this price.

Cost of Filer Replacements

The Panasonic purifier filters for both models cost just under $45 and are called the Panasonic FY120XT filter replacements.

The Panasonic HEPA filters are able to block 99.97% of particles bigger than 0.3microns which is true HEPA standard. The filters used for the Panasonic are actually vacuum-able so the manufacturer says they wont need replacing for at least 3 years. In my experience, you will find probably find that you will need to replace these filters more often than 3 years. However as the filters are quite inexpensive this is not too much of a problem.

Both of these Panasonic air cleaners come with activated charcoal filters that will need to be replaced every year if you want to cut down odour smells. The Panasonic FY-520XT Charcoal filters cost $35 which again is inexpensive when compared with other charcoal filter replacements.


For such a small price tag the Panasonic range of air purifier perform exceptionally well. There are many happy customers on and we fully recommend this air purifier for customers on a tight budget.


IQAir Health Pro Air Purifier Video Review

This is the next video in our series of reviews and this time we reviewed the IQair Healthpro air purifier.

With this video, i was able to use PowerPoint to help use images to put my point across. We followed the main points about why the IQair healthpro purifier is so much better than the majority of air purifiers out there. I was able to use a screen capture program to film this so in future we should be able to make videos of this quality and higher.

The main points that we talk about in this video is:

1. The Amount of awards won – Consumer reports, Wired magazine…etc

2. Technology uses – 0.03 microns

3. Why Hyper HEPA deals with allergies.

4. Certificate performance – we know that this purifier can perform

5. Silent design

6. Used in Surgery

I still think this video is a bit boring.. and should move a bit faster. Next time we are going to work with music and try and up the tempo a little. I will also get more creative with the flip cam so keep checking the blog.

Aprilaire air cleaner

aprilaire logo

Aprilaire are known for creating high quality whole house air purifiers. The first air cleaner to be released was the 5000 Aprilaire electronic air cleaner which hit the market in July 2000. Now the 5000 model is joined by the 2000 and 4000 range of media air cleaners.

Whole House cleaners are purifiers that are attached to your house furnace system and require a HVAC technician to install them.


Here are some quick plus points of the 5000 Aprilaire Air Cleaner

  • The manufacture says that the house air cleaner can deal with at least 95% of air particles that are bigger than 0.35 microns.  In comparison, some house furnace air cleaners usually only have a 70% efficiency at blocking particle less than 0.35 microns.
  • According to the claims of Aprilaire – the system uses an electronic media filter that will require changing only once a year. This was found to be true by an independent LMS test which puts the Aprilaire at the front of its competitors in this regard.

Test Data Versus Other Whole House Air Cleaners


In an independent test results the Aprilaire was rated second in its ability to remove air particles in comparison with the Carrier Infinity, Trane CleanEffects and the Honeywell F300.  The Aprilaire air cleaner was found to remove at least 90% of all air particles bigger than 0.3 microns.

How Does  Aprilaire Air Cleaner Work?


Unlike a lot of whole house purifiers, the Aprilaire uses a 2 stage process of electronic ionization matched with a micro-fibre filter. The electronic stage charges the surrounding particles which are then picked up by the small fibre filter.

In comparison most of the residential air cleaners use just one technology such as the Honeywell Fx00 range which use only electronic filters. The benefit of using two technologies is that the electronic unit will make it easier for the filter to pick up particles. As particles are charged they are made heavier which means that it will be easier for them to be caught in the filter.

Most electronic air cleaners will require cleaning regularly but with a combined system it seems that you will only have to replace the media system every year. The cost of 2 of these Aprilaire 5000 filter media cost just under $60 on (which is cheap!)

What About The Problems?

Cleaning 90% of particles bigger than 0.35 microns is good but this is only 10% of the air particles in the air! You need a purifier that can stop 95% of particles bigger than 0.03 microns.

Whole house air cleaners sound like the perfect solution but there are many faults with the concept. In brief a whole house air purifier will only clean where the main airflows exist. You can read more about this problem by reading this article: Do Whole House Air Purifiers Work?


As the independent results show the Aprilaire range of air cleaners are some of best whole house air purifiers on the market.

The problem is due to the fact that  this unit is a whole house air purifier. Time and again these house cleaners fail to live up to expectations.

Whilst the Aprilaire air cleaners are the best out of the bunch i would still not recommend them. At a cost of $600, you will get more clean air for your dollar if you choose a portable air purifier.

Iqair Healthpro Plus

I am sure you have already heard of the Iqair Healthpro plus purifier as it has won numerous industry awards. The Iqair plus purifier is the Cadillac of the air purifier world. The reason that the Iqair purifier is so well respected is because of the sheer amount of particles that in can block using its four stage filter system.


The average purifier will be able to stop most particles over 0.3 microns – which is small but in fact 90% of all airborne particles are actually smaller than 0.3 microns! When people complain about their air purifier not working its probably because most purifiers only remove 10% of all the particles in the air. If you suffer from a pollen allergy or asthma, 10% will be useless to you.

The IQair includes a HyperHEPA filter as part of its four stage process which can deal with particles down to 0.003 microns! The guys at IQair actually guarantee that this purifier will remove at least 99.5% of all particles bigger than 0.003 microns.

Finally we have a purifier that can successfully remove enough particles to relieve the symptoms of an allergy sufferer. The IQair plus purifier removes particles that are 100 times smaller than those that are picked up by your average high street air purifier.

Is performance certified?

Yes, whilst most air purifier make wild claims about their machines,  IQair actually test your machine and filters before it is sent to you. Each purifier will come with a 2-page performance certificate that is filled out by hand by an IQair technician.

So how does the IQair Purifier actually work?

IQAir-HealthPro-Plus-InternalFirst Stage: A micro-particle filter that removes the largest particles such as pet dander, spores and pollen particles.

Second Stage: Activated carbon filter that works on removing the odour causing compounds.

Third Stage: Chemisorptions using pellets which is able to remove toxic chemicals that are found in the home such as formaldehyde.

Fourth Stage: This is the nano fiber Hyper HEPA filter that will remove 99.7% of particles under 0.3 microns and 99.5% of particles larger than 0.003 microns. This stage will catch all viruses, bacteria and even particles caused by smoke and automobiles.

If your fed up of using an air purifier that fails to remove enough particles then we suggest you check out this purifier from IQair.

We understand that the IQair healthpro can just be way over budget for some customers so we suggest that they look at getting similar performance for less money with a Sharp air purifier. Whilst the Sharp air purifiers are good, nothing can compare to the IQair healthpro Plus.

Ionizer Air Purifier


Air Purifiers are created to clean the air off problem particles such as dust, pollen and dirt. One of the recent technological advancements are ionizer air purifiers that use ionization cleaning technique. ionizer_air_purifier

To understand how ionizer air purifiers work you need to understand a little bit about the ionization process.

The first thing that happens is that the ionization unit charges the air with a release of electrons that in turn charge the all the particles in the air. Now all the particles including the dust, pollen and bacteria are charged negatively so are heavier and are attracted to the positive plates of the ionization unit.

Negative ions can also provide a feeling of well being and can be compared to the air near a waterfall or on the beach (places where natural air negative ions are high.)


Many air purifiers will combine an ionization air purifier with an other type of filter such as HEPA or Activated Carbon. Ionization units can help to improve the efficiency of other filters as it increases the size of particles and thus makes it easier for them to be caught in the filter.

One of the benefits ionizer only air purifiers is that they do not require expensive filters but will still be required to be cleaner every few days. In our experience air purifiers that only use ionization are not that helpful. Usually for most people they will require this to be matched with a least one type of filters, we recommend HEPA or activated carbon.

If you are only looking to remove basic pollutants from the air such as dust and want to increase your rooms level of negative ions then maybe a ionization only purifier will be perfect for your home.

Overall we think that ionization units are awesome as they help to increase the efficiency of normal air purifiers. We would always recommend going for a purifier that includes some sort of ionization facility.

Sharp Air Purifiers are of often called plasmacluster air purifiers and are manufactured and designed by the global Japanese electronics company – Sharp. Sharp first started producing products in 1912 and went worldwide in 1956. The plasmacluster air purifier was first introduced in 2003 and became a national best seller.

Sharp air purifiers use an ozone free ion-oxidation technology to clean air of pollutants. Sharp air purification technology works via active purification rather than the riskier ozone treatments that other industrial purifiers use.


The Ion technology inside a Sharp purifier releases negative and positive ions to the surrounding air. The charged ions in the air are then attracted to air based pollutants which oxidises and thus eliminates the pollutants.

Sharp Purifiers are perfect for removing mold spores, viruses, fungi, microbes and even bacteria.

The Sharp purifiers are some of the most technological advanced units available with computer chips used for all on-board sensors. With Sharps history of strong research in the field of electronics, the purifiers rarely suffer from any electronic error malfunction.

Unlike cheaper models on the market, the sharp purification system allows for all aspects of the purifier to be controlled manually. Users can modify the noise level, filter usage and energy by optimising the unit via the on board controls.


Sharp Purifiers include both an activated carbon filter for removing odours and gas matched with the plasmacluster ion function. The carbon filter is unique for every sharp purifier in that it can be easily cleaned and then replaced for repeat use.

The only problem with Sharp purifier is that the gaskets and valves are not as tight as i would prefer. However Sharp have used this issue to their advantage as this helps to reduce weight and considerably reducing the sound output to less than a whisper.

I have been using air purifier since 1970’s and i now always have my Sharp air purifier by my side. I will continue to buy more sharp purifiers and will keep recommending them to my customers.

Honeywell Air Purifier with Permanent Filter

The Honeywell tower purifier comes with a permanent HEPA style filter which is able to catch around 99% of pollutants from the air. The one major benefit of the Honeywell air purifier is that it comes with a lifetime filter! With this filter you will never have to go to the shop and buy a filter every again. When the filter is full of particles you just have to pull it out of the purifier and wash it in the washing machine. You can also just vacuum Honeywell HEPA filters to quickly clean them without having to wait to wash them.

We found that the Honeywell purifier was really quiet unlike some other branded purifiers so you can leave it on when you need to work hard.  It comes with a pre-filter which is perfect for picking up large particulates and means that you won’t need to clean the main filter as much. We recommend that you only choose an air purifier that comes with a separate pre-filter.

This Honeywell purifier comes with a 5 year guarantee and Honeywell are a respected manufacturer both online and offline.
We give this purifier the following marks:

  • Tobacco Smoke = 98/100
  • Pollen/Hayfever = 90/100
  • Dust / dust mite allergy  = 90/100

With 3 speeds this purifier will allow for you to customise how fast you need to clean the air.
