Honeywell 18155 SilentComfort Permanent, True HEPA Air Purifier

I receive quite a few emails asking for product recommendations. The majority of them come from people who suffer from allergies and are looking in particular for an air purifier that will help them with their ailments. As it happens there is one air purifier, which even though it has been on the market for several years now, is difficult to beat. It is the SilentComfort Permanent True HEPA Air Purifier from Honeywell, otherwise known as the Honeywell 18155.

This air purifier is not just for allergy sufferers either since it is as efficient at removing allergens from the air as it is other airborne particles in addition to general household odors. In spite of the fact that there are many newer models on the market, the Honeywell 18155 SilentComfort is still what I would call the best Air Purifier for the money due to its excellent performance and low price.

I hope you enjoy reading my review. As ever, please leave a comment if you find it useful.

What we really liked about the Honeywell 18155:

  • Easy to maintain and clean
  • Good, robust and safe design
  • Electronic filter clean reminder; quietly cleans the air with no cold exhaust draft.
  • Easy to clean with household vacuum twice a year
  • Uses a True HEPA filter that never needs replacement
  • Removes up to 100-percent of bacteria and germs that pass through
  • Air purifier with HEPA filter for rooms up to 197-square-feet

Honeywell 18155 SilentComfort – You Will Notice the Difference Immediately

This air purifier from Honeywell is as good as any that they have produced so far. In order to see how well it works it is a good idea to read the views of a couple of recent users. These are people who suffered from health problems due to the bad quality of air in their homes. In the first case, the Honeywell HEPA filter allowed the couple to breathe again and to sleep at night. In the next case, the husband’s allergies were causing problems and his doctor actually made the recommendation to buy a HEPA air cleaner. In his case the Honeywell 18155 SilentComfort “has been a miracle worker.” He not only sleeps well but the sleep has allowed him to overcome his lack of energy.

Silent and Effective Performance

There are many features which make this the best air purifier in its class. One of the best is the fact that it is so quiet, even on high it is still quieter than an air conditioning unit and when it is on low, it just emits a gentle white noise at a level similar to a computer fan. With this model you will have no trouble watching the TV or sleeping at night.

It cleans a large volume of air as demonstrated by its CADR (Clean Air Delivery Rate) of 135 to 150, depending on which setting it is on. This is more than sufficient for medium sized rooms of 200 sq ft or so, where it equates to approximately 6 changes of air per hour. In addition to the true HEPA filter, there is also a carbon pre-filter, which keeps larger particles from clogging the HEPA filter. The carbon material also acts to reduce household odors.

This model is easy to transport from room to room due to its light weight.

No Ionizer Means No Ozone

The Honeywell 18155 SilentComfort does not incorporate an ionizer. This really is a good thing as it means there will be no ozone emissions. If ozone builds up in the house it can be bad for the lungs and allergies in general.

True HEPA is the Real McCoy

Many consumers are not aware that some air purifiers use filters that are HEPA-like in their design and others that use so-called True HEPA filters. There is no doubt that for best performance you need True HEPA as used in this air purifier. They promote better air circulation and are guaranteed to filter more particles from the air. Indeed a True HEPA air purifier will remove a minimum of 99.97% of airborne particles down to 0.3 microns from the air.

True HEPA is more efficient. In fact I have seen a Honeywell 18155 SilentComfort air purifier used to clean the air in a 1000 sq ft apartment. While the number of changes of air per hour is lower, it is still sufficient to do a good job on air quality and to remove odors.

The unit seems quite well built, and running on the low setting (which is where I leave it) there is very little noise.

Well Worth the Money!

Sure, there are cheaper air purifiers on the market but there is little point in spending less money if you don’t get a unit that will do the job. The Honeywell SilentComfort True HEPA Air Purifier has the benefit of advanced airflow design providing high speed and yet quiet operation…Buy Honeywell 18155 SilentComfort

Why Do We Even Need Air Purifiers?

Indoor pollution is on the increase. Indeed most people would be surprised to learn that indoor air pollution is actually 3 to 5 times higher than outdoor pollution. This is very important due to the fact that most of our lifestyles mean that we spend the majority of time in our homes.

Inside the home, there are many contaminants including general dirt and dust, mold, detergents and other cleaning agents, mites, pollen, pet hair as well as general household odors. The list of potential allergens goes on and on. For anyone suffering from a breathing problems such as asthma, this can be a serious situation.

The question is then, how do we improve the quality of the air in the home and therefore regain our health? The solution comes in the form of air purifiers. Although we can’t control the pollution in the outside environment, we can certainly control it indoors.

There are many manufacturers of air purifiers and also several different types. The efficiency of each type can vary enormously…Read More

Whirlpool® Whispure 315-CADR Air Purifier with True HEPA Filter, AP51030K

Whirlpool is an air purifier producer that always shows up in the top 3 when it comes to numbers of air purifiers sold. This popularity is borne out of the effectiveness of their products when it comes to allergy sufferers. With the release of their new HEPA air purifier it will be interesting to see if it matches up to the effectiveness and quality of their previous air cleaning products.

The Whirlpool AP51030K Whispure HEPA Air Purifier certainly looks good at first sight and happens to be excellent value for money because of the good value for it online.

Nevertheless the main issue is precisely how effective is this model when it comes to helping people with allergies? Please take time to read through my review. I hope you find it useful.

Whirlpool AP51030K review highlights:

  • For large rooms up to 500 square feet (filters the air 4.8 times per hour)
  • Clean Air Delivery Rate (CADR) of 315
  • True HEPA filter captures 99.97% of microscopic particles as small as 0.3 microns
  • Manufactured by a trusted brand
  • Simple to use electronic controls with 4 fan speeds and Turbo/Sleep modes
  • Use the quietest and highest efficiency air purifier filter technology

Extremely Effective Air Cleaner

Although touted as an air purifier for allergy sufferers, the Whirlpool AP51030K is equally adept at performing basic air cleaning. From removing airborne particles to zapping unwanted aromas, this air purifier really does do the job. If you have never used an air purifier you will experience the way the air feels fresher and ‘smells’ cleaner. You will also notice how there is no dust flying through the air, especially in sunlight.

The Whirlpool AP5103K really does help allergy sufferers. I hear many stories of people who formerly had to use their asthma inhaler regularly at night and can now do without it after running this air purifier overnight. The combination of the charcoal pre-filter and main HEPA filter in this air purifier work together to remove airborne allergens including pollen, dust, tobacco smoke, pet dander, mold spores and fabric fibers.

CADR Ratings With Regards to Allergies

The Clean Air Delivery Rate (CADR) for an air purifier is the result of tests done by the Association of Home Appliance Manufacturers - AHAM. It specifies the amount of particle-free air being delivered into the room, in other words the volume of air that is cleaned by an air purifier. As you would expect, a higher the CADR and larger room sizes go hand-in-hand.

The CADR is useful in determining the size of room that a unit can be used in without losing its effectiveness. The room area is roughly 1.5 times the CADR. The CADR for this Whirlpool unit is 315 and this means that it can cope with rooms up to 500 sq. ft. You need to be careful because some manufacturers specify large room areas without taking into account the CADR.

So what does this all mean for allergy sufferers? Well it depends on the type and severity of your allergy. The CADR and quoted room areas are really for people who have no health problems. If you have an allergy then you need to reduce the room area to two thirds or so. This means that the Whirlpool AP5103K can be used effectively for most allergy sufferers in rooms up to about 360 sq. ft. which is still a good area.

Runs Quietly

When reviewing any products it is important to look at both the pros and cons. Well one thing that seems to have crept into some user comments is the noise of the Whirlpool AP51030K. While the volume and frequency of sounds and noises affect different people in different ways, I would certainly say that this air purifier runs quietly. I say this not only from the noise that this air purifier makes but also from the perspective of comparing it against other units on the market.

If you turn it on Turbo right out of the box then you will be amazed at how little noise this makes. In fact I heard of someone who was worried it was not running properly due to the fact that it was so quietly. You only need to feel the breeze of air flowing out of the top of this air purifier to know that it really is shifting a lot of air. I can’t imagine anyone having problems sleeping with this air purifier operating in their bedroom. In fact they have even provided a Sleep Mode that ensures that you have an undisturbed night as well as saving energy.

Plenty of Options that are Simple to Use

This air purifier is easy to operate and the options for fan speed for example are intuitive and straightforward. The Turbo mode is a very good feature and many people use this when they are out of the home so that the air in the room is perfectly clean when returning. There are indicators which let you know if the carbon pre-filter or the regular filter needs replacing.

The Whirlpool AP51030K is nice and light, which makes it a truly portable unit that is easy to move from room to room. You might want to place it in the bedroom every night and the ease of transporting it saves the need to buy two units. It is also unobtrusive and can operate without anyone noticing it.

Ideal Air Purifier for Rooms up to 500 Square Feet!

This air purifier has the power to purify the air in rooms up to 500 sq. ft. It uses a true HEPA filter that is guaranteed to capture at least 99.97% of airborne particles as small as 0.3 microns. In addition to the HEPA filter, it contains a charcoal pre-filter that pre-cleans the air and also acts to trap unwanted odors. The unique Quiet Partner® System provides the highest possible efficiency air purifier technology.

The Whirlpool AP51030K HEPA air purifier is an Energy Star qualified unit and certainly merits a 5 star rating…Buy Whirlpool AP51030K NOW

The Benefits of HEPA Air Purifiers

Air purifiers differ gratly in their efficiency. Even though air purifiers you will see in shop come in all shapes and sizes, it is the filter or filters contained within it that are important. HEPA air purifiers provide many benefits such lasting longer and capturing more pollutants than any of the other types.

HEPA (High Efficiency Particulate Arresting) air purifiers were invented by the U. S. Atomic Energy Commission. They capture the smallest particles down to 0.3 microns, even including bacteria. This means that chronic allergies such as asthma are alleviated because the filters trap the particles responsible for allergies such as pollen, mildew, dust mites, dander, mold and chemicals from various common household products such as soap and detergents.

While it is possible to install HEPA purifiers directly into your heating or air conditioning systems, it can be expensive and you can’t take them with you when you move. A portable HEPA air purifier provides all the benefits mentioned above as well as the ability to place it in the position where it is most helpful…Read More
