Since the 80s, the average home size for every American family has been significantly increasing. According to CNN, 
in 1983, a typical American home can be as big as 1,725 square feet. 10 years later, the average home size reached as huge as 2,095 square feet. In 2014, the size even ballooned to 2,598 square feet. These numbers suggest only one thing — American homes will only get bigger and bigger.
This isn’t an issue because it almost certainly means a better socio-economic environment. However, since homes are made more and more comfortable, people also spend more time indoors. Unfortunately, staying indoors isn’t always safe for the family. According to the United States Environmental Protection Agency, the air quality indoors can be five times more polluted than the air in outdoor environments. And the main reasons for this are the way most buildings are built and the different things people bring indoors that can release toxic contaminants in the air.
Then again, even if our homes can be polluted, it doesn’t automatically mean that our health is absolutely doomed. Fortunately, there is a simple and workable solution in order to keep the air you breathe indoors safe and clean, and this is by using an air purifier.
At its core, these air purifiers work by removing all harmful toxins, pollutants, and allergens from the air you breathe, making sure that these substances don’t get to your lungs. Through this, you can enjoy living your life indoors while also making sure that you’re leading the healthiest life possible. 
The only downside is how to find the right home air purifier that can clean bigger spaces. If you have a smaller room, it’s easy to make sure that the same room will be cleaned thoroughly. However, those with respiratory conditions who live in rooms as big as 500 square feet and above, it’s a struggle to purify the air and make sure that it’s safe to breathe. Though smaller air purifiers can clean the said area, it will either take too long to fully get rid of the pollutant, or it won’t be as efficient to kill 99.97% of stubborn viruses and bacteria.
On top of this, there are also so many options claiming to be the best. Some are so convincing that they get people to buy instantaneously, only to regret their decision later on. To add insult to injury, some people find large room air purifiers hard to understand, and this is a valid feeling.
Each and every air purifier utilizes a different air cleaning method. This is the fact that makes it difficult to choose the one that fits your lifestyle, room size, and specific needs. Since we understand this predicament, we decided to round up the best air purifiers for larger rooms for you, along with their respective salient features. Through this product guide, we fervently hope that you can come up with a more informed choice.

Advantages of large room air purifier
Before we run down all the top 15 large room air purifiers that made it to our list, let’s go back to basics. So, what is an air purifier and how does it function? How can it help you?
Simply put, air purifiers clean the air you breathe. It comes with a specialized filtering mechanism that targets and singles out microscopic particles that can be harmful to your health.
If there are lesser harmful particles floating in the air, there is an equally lower chance that you breathe them in. If you don’t have an air purifier filtering your indoor air, you only have to rely on your lungs to filter these airborne contaminants. This is the very reason why people often get sick. And if you have respiratory conditions like asthma or allergies, first-hand airborne irritants can get really painful.
For those who don’t have any respiratory problems, you can still feel a dramatic health improvement if you’re using an air purifier at home. The reason behind this is that high-quality air purifiers can trap almost 100% of air pollutants that can enter one’s lungs and nasal passage. If the air is pre-filtered, much of the stress will be taken off your lungs to make sure that you only breathe fresh, clean air while you’re indoors.
In the case of large room air purifiers, the mechanism is the same, except that it can clean a larger space faster and more efficiently. Here are the more specific benefits and advantages of having a large room air purifier.
Wider capacity in aiding people with allergies
There are more than 50 million people in the US that suffer from respiratory and nasal allergies. These airborne allergens can wreak havoc in one’s immune system, leading to many discomforts and unpleasant symptoms such as painful headaches, sneezing, coughing, and eye irritation. With the use of an air purifier specially made for people with allergies, you can create a home that’s allergen-free. Plus, if you need to also filter the air in your living room, offices, and other bigger spaces, a large room air purifier can take care of the job.
Lessens asthma triggers by providing bigger cleaning coverage
There are over 300 million individuals all around the world who suffer from asthma, the very same disease that accounts for over 14 million yearly doctor visits. The major contributing factor to asthma is having to breathe nasty, polluted air in. Air purifiers can clean indoor airs to help asthmatic individuals stay away from different respiratory issues.
If you’re asthmatic, anything can trigger your allergies. This means that you have to make sure that the environment you stay in is free from allergens that can spur any allergy attack. With this said, you shouldn’t limit your air purifier to your bedroom. Since you also move around the house or office, you need to make sure that everywhere you go is safe and well-sanitized. This is where large room air purifiers can offer so much value. They can filter rooms as huge as 11,000 square feet.
Prevent dust build-up in bigger rooms
Even if you try so hard to keep your house clean, in one way or another, dust will always end up accumulating on every nook and cranny. Unfortunately, these dust will also end up attracting dust mites, something that most people are allergic to. If you’re looking for an excellent way to cut these dust and dust mites down, you can use your air purifier to suck in and trap these particulates before they start collecting in every corner of your home. If you have an air purifier with a bigger purifying capacity, you can make sure that every nook and cranny of your house is dust-free.
Get rid of mold and mildew in every corner of your house
It doesn’t need further explanation why mold spores are toxic to one’s health. Unfortunately, even if people knew the harm caused by molds, most of them still end up developing chronic illnesses because they’re exposed to mold for a long time. The good news is you can use specialized large room air purifiers to rid your home or office with mold and bacteria. Since its coverage is wider, you can guarantee everyone’s health while indoors.
Trap pet hair and dander more efficiently
Studies suggest that 40% of children and 30% of adults have developed nasal allergies. And the main culprit behind these allergies is pet dander. Yes, you can take medications to combat pet allergies but this can be quite a hassle in the long run. Plus, it can take a toll on your budget, too. Aside from pet dander, you can also suffer from nasal allergies because of the build-up of pet fur or hair on your rugs, furniture, and other indoor fixtures. You can get rid of all these issues by investing in an air purifier for your living room and other bigger spaces in your house.
Get rid of smoke and its odor in larger room areas
Living with a chronic smoker will not only expose non-smokers to the dangers of secondhand smoking, but it can also expose everyone living in the same house to lingering odors that one would like to get rid of. The best solution for this problem is to invest in a large room air purifier that can detect and get rid of smoke and odor in bigger, wider spaces.

The main types of large room air purifier
Here are the four main types of large room air purifiers and a description of how each one works.
High-Efficiency Particulate Air (HEPA) filtration
When it comes to air purification, the HEPA filtering process is the gold standard. It comes with a highly dense filter that’s made of paper for trapping airborne contaminants. This is also known as the driving mechanism you’ll find in top-tier machines. According to experts, if an air purifier is labeled as a True HEPA filter, then that means that it can get rid of 99.97% of microscopic particles including those that are as minute as 0.3 microns.
Ionic filtration
This particular air purifying technology functions by emitting charged ions specifically targeting the airborne contaminant-latching air. Because of this unique mechanism, the impurities are forced to fall directly onto the floor and surfaces. There are ionic air purifiers that come with an electrostatic plate that actively collects and attracts fallen particles before it removes them from the room. Through this process, ultra-fine particles, those that are 0.01 micron in size can still be eliminated.
Carbon filtration
This filtering system specifically uses a unique kind of activated carbon made up millions of ultra-small absorbent pores. The said pores make a huge surface area that can trap odors, gases, and fumes. This type of filtering system is not designed to eliminate particles causing health problems. Instead, they target those particles that cause foul-smelling.
Ultraviolet (UV) light
This technology uses invisible UV light to attack pollutants. The said light is strategically contained within the air purifier instead of being released inside the room. The main goal of this purifying system is to kill viruses and bacteria inside the room by attacking and destroying its molecular DNA structure. Once done, the room gets cleaned, sterilized, and totally free from any particles that can make one sick.
Features of top notch air purifiers for large rooms
The next phase of the discussion will be centered on the features and characteristics that distinguish the best in class air purifiers for large rooms from the rest. These features in essence constitute the criteria, based on which the subsequent 15 products have been selected. Here’s a rundown of all the crucial features you can look into.
- Pre-filter: This is responsible for capturing larger particles like dirt and hair. Pre-filters also help in furthering the life of the air purifier’s internal filters.
- Antimicrobial treatment: This refers to the coating on your air purifier that prevents the spread and build-up of microorganisms and bacteria on its internal filters. With this mechanism set in place, you can lengthen the lifespan of your filters while also preventing the reintroduction of the trapped germs and particulates back into the air.
- Sensors for air quality: This particular feature will allow you to monitor the air for specific pollutants. Once identified, the device will automatically adjust its air cleaner level to immediately get rid of these particles.
- PlasmaWave technology: This is a safer, alternative air ionization method that stops the emission of negative ions. Instead, it uses water vapor to achieve a similar effect.
- Photocatalytic oxidation: This refers to the advanced filtering mechanism that works hand in hand with the device’s UV light in order to oxidize chemicals and eliminate volatile organic matter, fungi, mold, and bacteria.
- Capacity: To know the size that a particular air purifier can cleanse, you can multiply its Clean Air Delivery Rate (CADR) by 1.55. If your chosen air purifier has a less than 2x Air Changes per Hour rating, pass on it. Go for air purifiers that can purify the air in a space that’s way bigger than your room. This is the only way you can guarantee that it’ll be its optimum function.
- Operational efficiency: There is a specific air purifier for every air cleaning purpose. For example, you want to purify your air from airborne particles that can cause nasal allergies and other respiratory illnesses, go for those with true HEPA filters.On the other hand, if you want to get rid of bacteria on the air, go for air purifiers with UV light. And if you want to get rid of foul odor and smoke, choose air purifiers with activated carbon filters.
- Energy certification: Typically, a standard air purifier that’s continuously operating uses around 550kWh of electricity annually. This number is higher than the energy used by new refrigerators. If you use air purifiers that are Energy Star certified, you can cut down your energy usage by 60% compared to other non-Energy Star certified.This means you’ll be able to save 500 kWh in electricity per year.
