The 5 Best Air Purifiers (Updated Apr. 2018)


Do you live near some busy street in an urban city? Are there times when you simply don’t want to stay “holed” up in your living room as a result of the bad smells and or odor?

If you’re having trouble with room air pollution you are not alone. Many urban dwellers are having this same problem of improving the quality of indoor air.

In fact, studies carried out by the Environmental Protection Agency (EPA) indicate that the indoor air quality in many homes is 2 to 5 times more polluted than outdoor air!

Many try to handle the bad smell and air pollution by simply opening their doors and windows to let out the bad smells while allowing fresh scents from outside to rush in.

Unfortunately, simply airing out your house won’t get rid of odors caused by cigarettes, bacteria, molds, or dirt. Neither will open windows purify the air or kill harmful bacteria and viruses. Ironically, it has been proven that the breeze may actually inflame allergies even more!

But here’s good news: A good air purifier can help you get rid of indoor pollutants and make your home a hygienic place for you and your family.

Air purifiers filter the air and trap particles of dust, pollen and other allergens that could cause health problems for your family so you can enjoy the comfort of your home.

Honeywell 50250-S
Honeywell 50250-S

If you suffer from allergies and you are looking for a good air purifier that will help you ease your pains then the Honeywell 50250-S is what you need.

This air purifier is specifically designed for allergic people and anyone else who wants to remove common household odors and airborne particles like dust, pollen, mold spores, tobacco smoke, and pet dander. It can capture airborne particles 0.3 microns or larger and it’s AHAM Certified with CADR ratings of 250 for smoke, 250 for dust, and 250 for pollen.

To maximize its efficiency, the Honeywell 50250-S uses the patented 360° air intake and discharge. It has a powerful fan motor that draws in room air and releases cleaner air 360°.

When the air is drawn in the activated carbon pre-filter captures large particles and help reduce odors. While this is going on the True HEPA filter captures up to 99.9% of particles as small as 0.3 microns.

This Honeywell model is built using the SurroundSeal® Technology. This helps the system to minimize air leaks. Also, the patented 360° air intake and discharge ensure that the purified air is maximally circulated allowing for placement in every area of the room.

The air purifier also has a filter monitor (Intelli Check®) that will remind you when the filter is due for replacement. The system uses the air that passes through the filter to calculate this.

There is no doubt that the 50250-S is a powerful, inexpensive, easy to maintain and an effective air purifier for allergies. However, one noticeable defect is the fact that it is too noisy. Of course, you can lower this by reducing the fan speed.

Besides the high noise, the Honeywell 50250-S also has a tendency for high power consumption. But apart from these few cons, this air purifier is a great buy.


  1. It is highly efficient.
  2. Has wide cleaning capacity.
  3. Easy maintenance.


  1. This machine is noisy.
  2. High power consumption.
Whirlpool Whispure
Whirlpool Whispure

With a Clean Air Delivery Rate of 315, this air purifier is capable of filtering air in a 500 square feet room at the rate of about 4.8 times an hour. A powerful model, it comes well recommended by user reviews and consumer reports.

Whirlpool assures quality home appliances and this air purifier keeps with their tradition of delivering excellent performance with overall customer satisfaction.

The Whispure, by name, promises a quiet and effective cleaning of indoor air. It achieves that with a combination of clever design and quality materials.

HEPA filters are commonly employed by air purifiers to target a wide range of airborne pollutant particles. While many models promise up to 99% removal of airborne pollutants, only those air purifiers that have true HEPA filters will deliver on their word.

With the Whispure, you can be assured of quality. It features a three-stage filtration system that is made up of a pre-filter, a carbon filter, and a true HEPA filter.

Firstly, the outer grill on the air purifier acts a lasting pre-filter. It captures the larger particles. This ensures better filtration and also protects the inner filters for durability.

The carbon filter, the next line of defense, adsorbs particles that cause unwanted odors in the home. It also works to stop large particles and thus prolongs the life of the HEPA filter.

The HEPA filter delivers maximum filtration by removing up to 99% of particles, even those as small as 0.3 microns. This covers most general airborne pollutants in households. These pollutants (mold and fungi spores, pet dander, dust, pollen, etc.) reduce indoor air quality in your home and aggravate symptoms of allergies and asthma.

An air purifier with an effective true HEPA filter will be your best ally in your efforts to rid your home of these pollutants and allergens.

The unit comes with easy to use electronic controls that can be operated simply. It offers four fan speeds, so you can adjust the cleaning, white noise, and power consumption as per your requirements.

True to its name, it does keep a quieter profile than many others in the category, especially in the sleep mode. Sleep mode lets the user put in a setting for sleeping hours. Here the purifier automatically switches into the lowest fan settings so you can run the unit continuously during sleeping hours.

You can always power it up into turbo mode for maximum cleaning during other hours. User reviews do give this model a good report on its overall performance and recommend the unit’s energy efficiency as well.


  1. Very reliable and sturdy.
  2. Large room coverage.
  3. Quiet operation.
  4. Doesn’t release ozone into the air.


  1. Generates a little bit of heat.
  2. No air quality sensor.
  3. Costly replacement filters.
Honeywell HFD-120-Q
Honeywell HFD-120-Q

While consumer review camps stand divided on ionizer technology in air purifiers, this model from Honeywell assures the best in ionizer technology and durability. This is a model built for quiet efficiency. It can deliver clean air in rooms of up to 186 square feet.

It also comes with a permanent pre-filter so you can do away with needing to replace filters every now and then. This feature also makes a difference to how this purchase pans out cost-wise in the long run.

The permanent IFD filter can be taken out, washed, vacuumed and put it back in place to continue to do its job. Consumer reviews do welcome the permanent feature as a convenient alternative to the usual filter replacement system on most air purifiers.

This best air purifier also features an electronic filter check indicator. Timely and easy maintenance of the air purifier is simplified with this system.

The ionizer feature of this air purifier targets airborne impurities in a unique way. An ionizer generates charged particles (ions) and sends them out into the air. These ions mix with airborne particles from common household pollutants.

These impurities are then forced to attach themselves to a nearby surface. They can then be cleaned up easily with vacuuming. The process grounds airborne impurities so they can be disposed of simply.

Ion generation technology continues to be debated in consumer forums. While there is no doubt that they are effective in cleaning the air, the feedback from the medical community has been concern over the emission of ozone gas in air purifiers with ion generators. Ozone is a lung irritant and may affect people with chronic lung conditions.

The edge that ionizers have over other methods is that as opposed to drawing the air to get past a filter, this method sends out particles to bring down airborne impurities, quite literally.

Other air purifying methods trap impurities. This method seeks them out and grounds them – this way, users only have to do a bit of easy vacuuming and not worry about replacing filters and the costs.

This Honeywell model also has an oscillating function for increased effectiveness. User reviews also indicate that this air purifier fares really well on the white noise front: it is quieter than others in the category.

Durability and cost-effectiveness are important factors for any home appliance. Honeywell guarantees quality and excellent value. With good consumer feedback on energy usage and operating costs, this air purifier seems to fare greatly in user forums, notwithstanding the debates surrounding ionizers in general.


  1. Low power cost and noise.
  2. Cheap Price.
  3. Good purifier for allergies.


  1. Less effective for larger areas.
Honeywell 17000-S QuietCare
Honeywell 17000-S

Another great performer from Honeywell, this air purifier addresses all key issues for air purifier users: multiple filtrations, reduced operating noise, true HEPA filter that can be vacuumed, easy to use controls and guaranteed high-quality performance. This model can arrest airborne impurities in rooms of up to 168 square feet with ease.

Firstly, the multiple filter system on this model circulates the air continuously at roughly the rate of six times an hour. The powerful intake system ensures that the filters can work intensively to clean the air.

Pollen grains, pet dander, mold, fungi, spores, tobacco smoke, airborne dust mites, bacteria, and viruses are the usual suspects that pollute the home: they don’t stand a chance with this purifier. This super-effective air purifier is a great ally for allergy and asthma sufferers.

The filtrations systems rout 99% of all the airborne impurities that aggravate these conditions. The true HEPA (High-Efficiency Particle Arrester) filter in this model delivers superior purification. It easily traps impure particles even as small as 0.3 microns in size.

Just for scale, your hair is probably around 200 microns in size. HEPA filters are universally appreciated for their effectiveness in fighting airborne pollutants.

Guarding the HEPA filter and doing away with unwanted smells is the job of the activated carbon pre-filter. This filter takes care of larger particles so the HEPA is free to go after the tiny particles that pollute indoor air. It also adsorbs vapors and odor bearing particles so your indoor air is not just clean but fresh as well.

The filters on this model are monitored by Honeywell’s inbuilt Intelli Check system. This intelligent electronic monitor will let you know when your filters need to be cleaned or replaced.

The true HEPA filter on this model can be taken out and vacuumed for an extended life. The durability factor adds greatly to the cost-effectiveness of this model. The carbon filter may need to be changed about once every three months, especially if you’re dealing with strong odors.

The Intelli Check monitoring system allows each filter to be individually monitored. The system will tell you how much life a filter has left and will let you make the necessary replacements or maintenance as and when it is required.


  1. Easy to install and move.
  2. Minimal maintenance required.


  1. This air purifier is noisy.
  2. Minimal coverage.
Winix PlasmaWave 5300
Winix PlasmaWave 5300

Winix air purifiers are noted for combining value with performance. The same goes for this model. It boasts a Clean Air Delivery Rate (CADR) certification that can cover up to 350 square feet. This makes the WAC5300 well suited to large rooms – family living rooms, common indoor spaces or master bedrooms.

This Winix model offers a combination of innovations to take on 99% of airborne household pollutants.

The Winix WAC5300 features a 3 Stage Air Cleaning system. Multiple filters combat different airborne polluters.

Pre-filters deal with larger particles like lint and hair. This feature contributes to extending the life of the core HEPA filter. These filters also combat a wide range of odor-carrying particles: this is great for keeping indoor air smelling fresh and clean.

This air purifier comes with a true HEPA filtration system. HEPA filtration systems are essential in the battle to keep airborne allergens at bay.

Many an allergy and asthma sufferer has indicated in their consumer reviews that the effectiveness of air purifiers with HEPA filtration systems exceeds all others.

The average width of the human hair is about 200 microns – true HEPA filters will put away anything as small as 0.3 microns. This covers most common airborne particles in households, including pet dander, fungi spores, mold, dust, etc.

The WAC5300 offers Plasma Wave technology as a key feature. This innovation is what makes it different from others in the category.

Many air purifiers offer ionizers that generate ions. These ions attach themselves to airborne pollutant particles and fall towards a surface-floor, wall or furniture. They then need to be vacuumed.

Plasma Wave technology used in this model is different in that it does not just weight the polluting particles down. It goes on to break apart these particles at the molecular level. Most importantly, it does so without producing harmful ozone.

Ozone is a lung irritant and can be risky for people with chronic lung conditions. Winix’s Plasma Wave technology delivers the result without the risk.

This model also features an Air Quality Sensor with Auto Mode. When the purifier is switched to Auto Mode, the Air Quality Sensor works continuously to monitor the quality of air in the controlled environment.

Any new contaminants will be dealt with by an automatic adjustment of settings to deliver optimal performance in the face of new threats.

This air purifier comes with four fan speed settings. It can go really quiet when you need it to or power up to turbo for when you need to maximize its cleaning abilities. This model also bears an Energy Star label: great for keeping operating costs and energy usage as low as possible.


  1. Very good performance.
  2. Air quality sensor.
  3. Designed to run quietly.


  1. Short warranty time.
  2. Generates ozone.

What Is an Air Purifier?

An air purifier works by cleaning the air in a room from small contaminates, mostly the small particles that float around the air unseen.

Purifiers work by reducing the chances of reactions from allergens, cleaner air to breath can help those with breathing related problems by providing air that is free from air-borne particles.

These can help clean air from many types of bacteria, dust to help asthma sufferers, air-borne viruses like the flu, smog, fumes, and smokers can find these beneficial but the main problem solver is for allergy sufferers, an air purifier will help alleviate allergy symptoms.

Why Does One Would Like an Air Purifier?

Unless you live in a cave, then you have more than likely heard of an air purifier. Now though you may have heard the name or seen it on the world wide web or television, have you ever thought about how it could benefit you if you had an air purifier in your home?

This is why we’re going to go over 4 different reasons on how an air purifier can benefit you and your home. Air purifiers are not always a necessity, but either is that 72-inch flat screen in your living room.

Reason One: They make the air inside that you’re breathing day in and day out cleaner. We have already gone over how certain air purifiers can remove the toxins that are in cigarette smoke, but what about nonsmokers why should they have an air purifier in their home?

Because air purifiers can also clean mold, pollen, mildew, and pet odor as well, making your home cleaner and free of foul odors.

Reason Two: By removing all of these toxins from the air using an air purifier you’re making your home a healthier place to live.

Second-hand smoke is no good for you this has been proven over and over again. Air purifiers also make it healthier for people that have pet allergies, as a lot of people are allergic to cats, air purifiers can help those that have pet allergies.

Reason Three: Air purifiers help people with allergies, as stated above, and they also benefit people that have asthma. It is stated that the air that’s inside a home can be much worse than air that’s outside, especially for people that have allergy problems and breathing problems.

Air purifiers can help keep the air more natural inside of your home like the outside air is helping you breathe in nothing but filtered the air.

Besides your air conditioning or heating unit, there is not much more to filter the air, unless you keep your windows open all of the time. If the weather will let you do this, keeping your windows open is a great way to get some clean air inside your home and also give your air purifier a rest.

Reason Four: Air purifiers are becoming more and more popular, therefore there are more retailers that are out there selling them. More people are also being concerned about their health and the more that we learn about inside home air the more that we learn about all of the pollutants that inside air contains.

Air purifiers are extremely useful to pregnant women, newborn babies or the elderly as their immune systems are not up to par with the average youngster, and more precautions must be taken when it comes to the quality of air that you’re breathing in the day in and day out.

So there are some good reasons that you should think about getting an air purifier for your household. You must also take into consideration that there are several types of air purifiers that are specifically designed to eliminate specific kinds of pollutants that are in the air.

If you have a pet you’ll want to do research on an air purifier that is designed just for that, removing pet dander.

The most popular would probably be how to remove cigarette smoke, so make sure that you do the proper research on to what kind of air purifier that’ll benefit you the most and don’t just throw your money at the cheapest one that’s on sale that you see first.

Types of Air Purifiers:

If you have been conducting any looking around at all on air purifiers you’ve probably heard of HEPA air purifiers and ionic air purifiers, which seem to be some of the more popular types of air purifiers on the market today.

We will go over them both but we will also cover a handful of other types that you may be in the dark about.

  • HEPA Air Purifiers:

These types of air purifiers will need air filters in most cases, and depending on how dirty the air is in your home will decide on how often the air filter will have to be changed.

If you’re concerned about pollen, dust, mold spores, then this kind of air purifier will surely benefit you. HEPA air purifiers can remove 99% of the particles that are .3 microns or bigger. While these are sufficient for removing pollutants out of the air, they are not designed to get rid of odors such as tobacco smoke and pet dander.

  • Ionize Air Purifiers:

Get rid of particles from the air by “ionizing” them, particles .1 microns and up, a little different but a quite effective method of removing particles.

The majority of people will pick these types of air purifiers over the HEPA ones for a couple of reasons. For they’re a lot less noisy than HEPA air purifiers, this can be a huge deal to some people that are do not like the noise from a fan.

The other is they don’t need filter replacement, which in some situations can get pretty damn expensive. Like the HEPA air purifier, ionizers are not very effective in getting rid of foul smells from inside of your home, although there are some Ionizing air purifiers that are out there that are designed to get rid of tobacco smoke from the air.

  • Carbon Air Purifiers:

These are great for removing odors from the air. They use filters also, which depending on what exact model you have will determine how and when you must change the filter along with how much a filter replacement will be.

So if you’re the kind of individual someone that wants the air in your home to be odorless, then this will be the best air purifier for you, if you’re looking to remove allergens from the air, this is not for you.

  • UV Air Purifiers:

There are eliminating microorganisms that can cause diseases and viruses. They can also sterilize germs, bacteria, and mold. Not the best for allergens and odors though.

  • Hydroxyl Radical Purifiers:

If you’re looking for an air purifier that can do it all, or nearly do it all, then this is the type of air purifier that you’ll want to do a tiny research on. The only downfall is Biozone is the only one who uses hydroxyl purifying technology at the moment.

Biozone air purifiers won’t blow a hole in your budget either, they are not cheap but they’re not super pricey either. Based on consumer reviews, Biozone makes the best air purifiers.

With this, you should have a little bit of a better clue on what air purifier will suit you the best.

“Do Air Purifiers Work?”

How to Choose the Best Air Purifier for Your Home?

When choosing a home air purifier there are a few things you need to take into consideration. These include how effective they are able to remove airborne particles in your home and how quietly they operate. Here’s a simple guide:

  • Functionality:

This is definitely the first thing you want to look out for. What is the ability of the home air purifier to clean the air?

To determine this, you should check for the purifier’s Clean Air Delivery Rate (CADR) which is an indication of how efficient the air purifier is in eliminating tobacco smoke, dust, and pollen from the air. The CADR of an air purifier is measured in cubic feet per minute (CFM).

Large air purifiers can perform four air changes per hour so if the place you want the air purifier to cover is large getting the right size is necessary. However, you must understand that the larger the system the louder the noise they make.

So, to balance the appeal of a quiet machine as against the functionality of a noisier one you look for a quiet system with the highest air-movement volume.

  • Features:

Next to functionality you should also look out for how convenient it is to use the air purifier. A feature that makes it easy for you to know when the removable filter needs changing is something you will want to consider as this can help in a number of ways.

Besides, a purifier with a timer or sleep mode is also great as it can make it easy to program the filter to run or shut off by simply adjust the settings.

There are air purifier models that have air-quality sensors and will adjust the fan speed based on the number of particles the sensor detects in the air. So, when shopping for an air purifier carefully check the features of the brand.

  • Safety and Certifications:

Buying an air purifier that has some independent certifications is a sure stamp of how effective that purifier is. Some of the independent certifications you should look out for are the Edison Testing Laboratories (ETL) or Underwriters Laboratories (UL) certifications. These certifications ensure that your purifier meets North American safety standards.

  • Help and Support:

Though most air purifiers are easy to operate having an easy access to help from the manufacturer in case something goes wrong is necessary.

It is ideal therefore that when buying an air purifier you should check if there is a customer support. Is there a warranty or online technical support? How about FAQs, downloadable user manuals, online chat, etc? One or all of these should be available as they will come handy at some time.

“Air Purifier Buying Guide”
