Best Air Purifiers of 2018

Everything you need to know about air purifiers.

We have all complained about the diminishing quality of the air we breathe in outdoors. There is industrial pollution, emission from vehicles and smog that have all led to respiratory issues and lung cancer in the most unfortunate cases. This can be largely mitigated from affecting you in the home by regularly replacing your AC filter. Websites such as, allow you to order replacements online, so there’s really no excuse not to. However, did you know that the air inside your homes could be detrimental to your health as well? Didn’t think so!

There are numerous airborne particles that you inhale on an everyday basis which are harmful to your health, especially if you have allergies or asthma problems. If you’re having issues with your air ducts, call out someone like Willard Power Vac air duct cleaning service. Harmful air particles can have disastrous consequences for your health if you don’t sort them quickly. These particles cannot be seen by the naked eye and are, hence, easily ignored. If you have encountered respiratory and nasal issues lately, we recommend you install an air purifier in your home or workplace.

What Is an Air Purifier?

We live in an era when there is a technology-driven solution to almost all problems. When it comes to air pollution within homes, scientists have introduced what we call today ‘air purifiers.’ In the simplest of terms, an air purifier has been designed to remove pollutants and allergens from the air, hence the name. These purifiers tackle the following airborne particles:

  • Pollen
  • Dust
  • Dust mites
  • Smoke
  • Mold
  • Spores
  • Viruses
  • Bacteria
  • Toxins

With the help of an air purifier, these particles are removed from the indoor air, thereby making the air around you clean and safe to inhale. People with HVAC’s will want to consider whether they’re happy with the cleanliness of the duct. If you have any concerns then you should do what is best for your duct and your household by contact professionals who can clean it. This coupled with the air purifier installation, will result in you having fewer breathing issues and an improved immune system. An air purifier is a must-have if you have family members who are more likely to smoke inside the house.

Air purifiers are powered by technology to clean the air by trapping particles. A few purifiers are equipped with more than a single cleaning/filtration technology to ensure reduced air contamination. The different types of air purifiers and their built-in technologies have been discussed in the paragraphs that follow.

Types of Air Purifiers

As far as air purifying technology is concerned, there are five types of air purifiers that you can choose to install. Once you understand how each of these purifiers works, you’ll know which one suits your needs and preferences better. Let’s get down with exploring these different types of air purifiers.

1. HEPA Air Purifiers

HEPA stands for High-Efficiency Particulate Air, a technology that has been highly trusted when it comes to filtering air particles. This technology has been designed to trap 99.97 percent of the particles such as dust, pollen, viruses, mold, and bacteria.

A HEPA filter is made of a fine fiber-like material that resembles the shape of an accordion. This accordion shape makes for a maze that is used to trap the air that passes through it with the help of an air purifier fan. The more the air passes through this filter, the cleaner it becomes and the safer it is to breathe in. Any large particles cannot easily pass through this filter and are easily caught on it.

As for the smaller particles, the HEPA filter comes equipped with three mechanisms to trap these particulates. Mechanism 1 is called interception, where if particles come within one radius of a fiber, they stick to it. Mechanism 2 is called impaction, in which particles collide with fibers and are then embedded into them. Lastly, mechanism 3 is known as diffusion that allows the smallest of air particles to collide with gas molecules.

HEPA air purifiers are considered the most effective for cleaning up contaminated air, but they are not as effective in keeping your house free from odor, chemicals, and gases. Moreover, these filters require frequent replacement and can be costly.

2. UV Air Purifiers

UV technology is also a popular one with air purifiers, but it is used with particulate filter systems as it cannot effectively trap airborne particles. It has been considered the best choice for getting rid of bacteria and viruses, however.

A UV lamp is installed within air purifiers, which is used to destroy microorganisms that come in close contact with the UV radiation emitted from the lamp. UV radiation works to break down the DNA structure of such microorganisms, causing cellular or genetic damage.

A UV air purifier converts oxygen molecules and water into ozone and hydroxyl. The performance of a UV air purifier depends largely on the light wattage and frequency of exposure. The lamp must be closely monitored and replaced on time.

UV air purifiers can kill 99.9 percent of mold spores and can also prevent various illnesses caused via bacteria and virus inhalation, but they produce ozone. Ozone is an unhealthy and harmful pollutant. Moreover, these purifiers do not tackle allergens, dust, smoke, fumes and other harmful gases present in the air.

3. Ionic Air Purifiers

These purifiers use chemical injections or ion emissions to clean the air. Negative ions are made up of oxygen atoms and are useful in magnetically attracting airborne particles including dust and pollen. These negative ions are released into the air to easily bond with positively charged air particles, thereby making the air fresh, clean and healthy.

These purifiers are effective in masking polluted air, but they are not as efficient as HEPA filters at removing contaminants from the air. The fallen particles remain stuck on the surfaces in the room and can easily become part of it again if they loosen up.

Ionic air purifiers are powered with electrostatic precipitators that require rigorous cleaning on a routine basis to function as intended. Similar to other purifiers that have been mentioned above, ionic purifiers cannot rid your house of odor but are particularly useful against dust, dander, allergens, smoke, viruses, bacteria and fumes. People that work in welding are often exposed to harmful fumes and gases and more often than not will wear a respitory welding mask for their own safety but perhaps an air purifier might also be a good idea for their workshops.

4. Activated Carbon Technology

These purifiers use activated carbon to clean the air of contaminants. Activated carbon has been processed and made porous to be efficiently absorbent. It has long been used to purify water and during WWI, its use as an air purifier was discovered.

Activated carbon filters come equipped with molecular-sized pores that have immense absorption and chemical bonding characteristics. This is why they have been quite effective in capturing pollutants from the air. The pollutants comprise of chemical emissions, gases, tobacco smoke, and odors. The good thing here is that these various forms of air pollutants cannot be released back into the air, hence preventing re-contamination.

These purifiers are recommended for use by individuals who have a sensitivity to odors, smoke, gas and other volatile organic compounds (VOGs) that are a source of irritation for those with asthma and allergies. However, these air purifiers fail to capture pollen, dander, dust, and mold from the air.

5. Ozone Air Purifiers

Ozone air purifiers use ozone to clean the air. Although a popular type, this air purifier has been disregarded by health professionals who claim that constant and prolonged exposure to these purifiers can ignite asthma symptoms and damage the lungs.

Moreover, indoor air particles can take months or even years to react to ozone, making these air purifiers virtually ineffective. Ozone cannot effectively be used to get rid of dust and pollen, making it all the more inefficient.

If you had to make a choice, use HEPA filter technology to create the ideal indoor environment.

What Is a HEPA Filter?

As previously mentioned, HEPA filter air purifiers are considered the most effective when it comes to cleaning indoor air, all thanks to the HEPA filter. A HEPA filter is made from interlaced glass fibers that have been twisted and turned to create a fibrous maze. When air particles come in contact with this web, they are disposed from the air in the following ways:

  • Direct Impaction – The larger contaminants including dust, mold, and pollen are usually traveling in a straight path. When they collide with the fiber, they stick to it.
  • Sieving – Since the particles are larger than the gap between any two fibers, they are effectively entrapped.
  • Interception – Owing to inertia, the particles continue on their path and stick to the sides of the fibers.
  • Diffusion – The smaller particles move more erratically relative to the larger ones and when they hit the fibers, they have no option but to stick to it.

HEPA filters can successfully trap particles as tiny as 0.3 microns, which, according to scientists, is the most penetrating particle size. The American and European HEPA standards vary such that European filters only capture as much as 85 percent of particles, whereas the American standards dictate that for a filter to be HEPA-certified, it must capture 99.97 air particles with a size of 0.3 microns. In America, this filter is often referred to as the following:

  • True HEPA
  • HEPA-type
  • Ultra HEPA

Things to Look For When Buying an Air Purifier

If you are thinking of buying an air purifier, here’s a list of factors you must take into account before making a purchase decision:


This is probably the most important of all. Without an adequate need, you will have no reason to install an air purifier at home. However, you may not be aware of potential health risks that contaminated indoor air poses. In order to find out, keep reading till the end of this article. If you hadn’t thought of a reason to purchase and install an air purifier, you might have one by then.

Possible Allergies

This makes up one of the many reasons that people decide to install an air purifier at home. You could have a dust allergy, allergy from pollen or asthma. All of these require cleaner air to breathe in. You cannot be wearing masks inside the house at all times to avoid inhaling dust and pollen.

Furthermore, if you have pets and there is a family member allergic to dander, you definitely need an air purifier to prevent allergies. Air purifiers can effectively clean up the air and get rid of dander, making it perfectly safe for those with allergies. Thus, you need to identify your and your house member’s allergies and select a purifier that can effectively tackle the air pollutants that are responsible for triggering these allergies.


This is another vital feature that you need to consider when buying an air purifier. Purifiers come in all sizes and either cater to a single-room space or have been designed for industrial use. Whichever purifier you intend to buy will state the square foot coverage that it can accommodate. Measure the room that you are buying it for and match it with the specification given on the air purifier.


In addition to matching the room size, if you have allergies or asthma, look for its ACH (air changes per hour) rate. If it states a high ACH such as 4, this means your air purifier will clean the air in its surroundings at least 4 times on an hourly rate, so you get a more frequent supply of fresh and clean air.


If you are buying a portable air purifier, you can only install it in a bedroom or one-room space. Your purchase decision will depend on where you are planning to keep it. Whole house air purifiers have gained acclaim in the recent times, and these can be kept to provide clean air throughout the house.

If you don’t want to invest in different air purifiers for every room but still need something to cover every space you are in, buy a portable purifier that comes equipped with caster wheels. You may then take your air purifier along with you to every room you go to.


Filters require frequent replacement, and the maintenance costs must be estimated prior to making a purchase decision. HEPA filters are to be changed every year, while activated carbon filters last for 6 months. Take into consideration the maintenance costs of each purifier and purchase one that you feel is manageable. This purchase is not a one-time expense and will cost you money over time, so you need to make an informed decision.

While keeping all of these factors in mind, you can also look for a few of the following features when buying an air purifier:

  • Caster wheels
  • Moving handles
  • Remote access
  • Digital controls
  • Adjustable speed of the fan
  • Programmable timers
  • Filter change indicators
  • Air quality sensors

Different brands will have different features that you might like in your choice of the purifier. Choose one that fits perfectly with your needs and specifications.

Impact of Bad Air on One’s Health

If you did not know the health risks associated with poor quality indoor air, you need to give this section a quick read. It’s not just the outdoor air quality that causes health issues, but the indoor air also contains pollutants and particles that can become a source of major health issues, a few of which have been mentioned below.

Short-Term Impact

Poor quality of indoor air can be detrimental to the health of children and adults alike. The various respiratory issues include nasal congestion, nosebleeds, dyspnea, sore throat, wheezing and lung disease.

The possible symptoms will include sore eyes, headaches, sneezing, fatigue, dizziness and dry throat. If you have come across a few of these, you need to have an air purifier installed at home. In healthy adults, poor indoor air can lead to the constriction of blood vessels that can be further translated into lung and heart conditions in the future.

Long-Term Impact

As for the long-term effects of poor quality indoor air, it is essential to mention here that pollutants that come into direct contact with the human body are absorbed by the tissues. These are then added to the blood, causing clogs in the arteries. These pollutants or air particles can also damage brain tissues if too much of them are absorbed into the body. Other long-term effects have been uncovered in the paragraphs that follow:

Effects on the Brain and Nervous System

Harmful air particles can cause alterations in the blood-brain barrier, leading to the degeneration of neurons and white blood cells. Plus, when absorbed by the body, these particles can lead to plagues and deposits that have been found to have caused diseases like Alzheimer’s, dementia and insomnia.

Effects on the Immune and Respiratory Systems

Air pollutants can become a major source of allergies, which is a response of the immune system to bacteria, viruses, and pollen. Prolonged exposure to these indoor pollutants can cause existing allergies to become aggravated. This may eventually lead to asthma and permanent cellular inflammation. Furthermore, these indoor air contaminants can become a source of severe lung disease and dyspnea.

Effects on the Liver and Heart

Air pollutants can lead to liver cancer, liver fibrosis or cirrhosis in case of prolonged exposure to viruses, bacteria, and pollen found in the indoor air. They can also harm the kidneys if these toxins and wastes remain inside. Scientists have discovered a relationship between pollution concentration and chronic kidney disease and failure.

As for the heart, when blood vessels are blocked by these air pollutants, they become prone to exploding and causing a heart attack. Air pollution is also a source of atherosclerosis, high blood pressure, and cardiovascular disease.

Effects on the Eye

Eye irritation is common if you have been breathing in polluted indoor and outdoor air. Poor indoor air quality can cause dry eye syndrome, and these air pollutants can cause alterations on the ocular surface, leading to long-term vision loss.

Polluted air is not bad for only you; it’s equally calamitous for your pets. All of this makes keeping indoor air quality optimal, so an air purifier becomes inevitable!

Air Purifiers – FAQs

Since we are helping you with your air purifier purchase decision, we must address some of the most commonly asked questions regarding air purifiers.

1. What Is Meant by the Term CADR?

CADR is short for Clean Air Delivery Rate, which measures the volume of filtered air that an air purifier delivers. This measurement has been developed by the Association of Home Appliance Manufacturers and comes in three forms: one for pollen, one for tobacco and one for dust. A higher CADR should tell you that your air purifier filters air faster with greater speed efficiency!

2. How Do I Know If the Quality of Air Is Bad?

As per the recommendation of EPA, you must check for potential health problems after a change in surroundings. Thus, if you have moved into a new house or refurbished or remodeled your current house, any resulting health issue may be caused by poor indoor air quality. You must immediately consult a physician.

Another method is to identify mold growth, condensation on the windows or walls, and other odor-causing sources and have them fixed. Better yet, install an air purifier.

3. What Does CFM Stand For?

CFM is an abbreviation used for cubic feet per minute, which represents how much cubic feet of air moves through the unit on a per minute basis. This is something that you need to consider when purchasing an air purifier. Usually, a higher CFM indicates that your air purifier does a better job cleaning the air and keeping its quality ideal for breathing.

CFM is influenced by fan speed, insulation, air flow, furniture, and the concentration of air pollutants in the air where your air purifier is installed.

How Long Should I Run an Air Purifier?

If you need fresh and clean air at all times, the air purifier must run continuously. However, you may set it on high when you are home, but it might be able to turn on low when you are away in order to save energy. Otherwise, it’s all up to you. Make sure to turn it on high when you expect more than usual emissions into the air such as dander or tobacco while keeping it at low at all other times.


Now that we have put together the best 12 air purifiers while covering other essential details regarding your purchase decision, you can confidently go ahead with buying an air purifier. Just make sure you know exactly what features you need to look out for and be mindful of any and all allergies you or your family members could be suffering from!
