Best Air Purifiers For Large Rooms in 2022

Several different types of particles exist within the air in your home. These include, but are not limited to, dust, dander, germs, smoke, and allergens. Other pollutants can make their way in as well, and potentially affect the health of your household. The seemingly obvious answer to this problem is to vacuum, which can help to reduce dust. The remaining problem is then the too-small particles that cannot be picked up by a vacuum. The only way to eliminate these particles is to introduce an air purifier.
Air purifiers work by drawing air in (including the unwanted pollutants that affect your health), then removing and cleansing the air of particles you won’t want to be breathing in. They are unlike humidifiers, which add beneficial particles (water vapor) to the air, and function more as air “processors.” Most air purifiers you will encounter contain a filtration system to trap particles as the air moves through them, but some air purifiers are still able to neutralize these particles without requiring a filter.

3) BLUE PURE 121
It is not unusual to see more than one product from Blueair in a guide for air purifiers, particularly when it comes to those best for large rooms! This is because the company puts an emphasis on high fan power. The Blue Pure 121 lists a suggested room size of 620 square feet, but we are confident that it can handle a much larger room with ease.
BLUE PURE 121
Blue Pure 121 features the exclusive Blueair air purification system as below:
Pre-filter – The pre-filter of Blue Pure 121 is situated outside the appliances itself, and acts as a means to catch the larger particles in the air. This pre-filter is washable, but can also be vacuumed when in a pinch.
Particle filter – The Blue Pure 121 uses polypropylene fiber filters, as opposed to True HEPA filters. Regardless, the polypropylene filter is able to remove 99% of allergens in the air, including dust, dander, and pollen.
Activated Carbon Filter – The activated carbon filter is housed inside the particle filter and effective against smoke, odors, gases and VOCs.
What the Blue Pure 121 lacks in smart features, it makes up for in power. This simple air purifier is the most powerful one available for less than $500, as confirmed by several different reviewers across the web. Additionally, the Association of Home Appliance Manufacturers (AHAM) gave this air purifier a CADR (Clean Air Delivery Rate) rating of 400 cubic feet per minute.

2) ALEN BREATHESMART 75I
Alen is a bit of an anomaly in that it is the first air purifier to offer a Forever Warranty. This policy provides excellent protection to the customer, but also reflects an impressive amount of confidence in the product. After years of manufacturing HEPA-type devices, the BreatheSmart 75i is the true HEPA flagship from Alen.
ALEN BREATHESMART 75I
The BreatheSmart 75i has a coverage of 1300 square feet, making it the best air purifier for large rooms from Alen. It is also worth noting that the fan power of this model outperforms its predecessors, with a CADR rating of 347 cfm and an air exchange rate of five times per hour.
Now, Alen BreatheSmart 75i can boast about its powerful 3-stage air cleaning system, with the core of a great True HEPA filter. Like its predecessors, the Alen BreatheSmart 75i combines its mechanical filters with the ionizer to push the limit of trapping 99.97% of allergens as small as 0.3 microns. There are 4 different True HEPA filters to select from, varying in specialty:
Pure: This is the standard True HEPA filter of Alen BreatheSmart 75i, which is able to capture 99.97% of pollutant particles as small as 0.3 microns such as dust, dust mites and pollen.
Fresh: The next level HEPA filter is an improvement upon the Pure, with the addition of Activated Carbon filter. This addition helps with the eradication of household odors and chemicals. This air filter can be an important component for those that are sensitive to VOCs.
Pet: This filter does not include the Activated Carbon filter, but instead uses Alen’s patented Molecular Conversion Powder to break down and remove heavy pet odors at the molecular level.
Heavy Odor: Alen made a few modifications to the Molecular Conversion Powder in the Pet air filter to make the new Heavy Odor filter. This filter is better suited to the removal of household odors from smelly kids and teenagers, kitchen garbage, and other everyday activities.
This air purifier features WhisperMax technology, making it extremely quiet. With this technology, the BreatheSmart 75i produces pink noise, which is similar to a low hum. For this reason, this air purifier is also a great choice for bedrooms, as the sound is not disruptive to sleep.

1) AIRMEGA 400S
As the current flagship in 2022 of Coway, we have high expectations for the AIRMEGA 400S. Indeed, this air purifier still manages to measure up with its impressive performance and features.
AIRMEGA 400S
With a coverage of up to 1560 square feet, the AIRMEGA 400S is ideal for large rooms. The CADR, usually provided by the AHAM, is not included in the manual for this air purifier, but through many tests, Breathe Quality determined an underrated CADR of 340 dust/ 350 smoke/ 400 pollen. These results do not reflect sufficient specs for large room coverage.
Just like Blueair, Coway is now combining their air filters for more streamlined installation. The AIRMEGA 400S machine contains:
Pre-filter – A powerful washable pre-filter is available to act as the “frontline” so to speak, and capture large particles/contaminants.
Max2 filter – This filter combines both the Activated Carbon Filter and True HEPA filter. The Max2 can capture up to 99.97% of airborne particles that are at least 0.3 microns, as well as reduce more than 99 percent of volatile organic compounds and reduces fumes such as ammonia and acetaldehyde.
The AIRMEGA 400s comes equipped with the Smart Enabled feature, making it the top rated smart air purifier available currently. The brand also features a unique Eco Mode, which changes the fan speed depending on air quality, and ultimately saves energy.

Everyone can benefit from clean air, however, it is particularly important for those with respiratory conditions like asthma or allergies. If you suffer from allergies or have asthma, you will most likely notice a reduction in symptoms if you use your air purifiers frequently, as it will help remove allergens, pet dander, and dust, and other particles that exacerbate your condition.
So which air purifier works best for large rooms? The following guide will help you determine the ideal air purifier for your large room, as well as showcase key features to consider before making a decision. Let’s see how they measure up!
Features To Consider With Air Purifiers For Large Rooms
Size
When shopping for an air purifier for large room use, the size of the appliance itself is also important to consider. Purifiers designed for large rooms can lean on the larger size; however, these machines tend to be more powerful and durable. Design-wise, these air purifiers can be very similar to portable air conditioners. Many air purifiers are designed with the modern home in mind, so even though they may be bulkier, they tend to fit well into most spaces.
If portability between rooms is non-negotiable, consider features like wheels and handles. Additionally, be aware of what a manageable weight is for you to carry easily between rooms.
Noise Level
Noise level is definitely an important feature to consider, particularly if you are shopping for a household with light sleepers or infants, or even an office space. Normal conversation is typically at a volume of about 60dB, which can be a good figure to use as a comparison when shopping for a quieter air purifier.
A whisper is approximately 30 dB and not-so-coincidentally, the majority of air purifiers operate at this level or lower when in sleep mode. Most air purifiers tend to be pretty loud when on their highest setting as the fan needs to move faster to circulate the air quickly; however, lower-speed fan options or sleep mode features can help to ensure a peaceful night’s sleep or a successful meeting with no interruptions from a loud air purifier.
Connectivity
The future is here, and many, if not most, air purifiers available are Wi-Fi enabled. Wi-Fi connectivity allows you to remotely control your air purifier from your smartphone, and usually allows for smart home connectivity as well. This is a great feature if you are on the go frequently and need to be able to adjust and control settings from your phone – it’s also great in case the remote gets lost!
Filters
We’re down to the nitty gritty of features to look for: filters. There are several types of filters available, and it is important to consider to ensure your air quality is at its best. The top air purifiers feature True HEPA air filters. These will remove up to 99.97% of all airborne pollutants as small as 0.3 microns.
HEPA Filter
A HEPA filter is capable of removing up to 99% of particles at least 2 microns. Pre-filters are great for filtering out larger particles, which can increase the efficiency of the main filter. Pre-filters are often washable, so there is no need to purchase replacements – a major plus when it comes to upkeep.
Another filter that is crucial to the quality of an air purifier is an activated carbon filter. These filters combat odors in your home, including both smoke and volatile organic compounds (VOCs). Activated carbon filters are efficient, but you will still require a carbon monoxide detector in order to know the exact level of CO in your house.
Air Quality Monitor
Air quality monitors are a feature that allow you to see the air quality numbers of your home or office in real time. Typically, these figures are displayed in the form of an LED colored ring, with different colors indicating different levels of air quality. Other times, the actual numbers are displayed on a small screen.
Air Quality Monitor
This feature can help to narrow down which household habits are affecting your air quality. And if you are not closely monitoring your air quality, there is usually an “auto mode” to do it for you. With this mode, the air purifier will monitor air cleanliness and adjust its fan speed appropriately. If one is not included, an air quality monitor can be purchased as an addition to your air purifier.
Room Size
Room size may be one of the most important features to consider, as it will drastically affect the effectiveness of your air purifier. All air purifiers you consider will provide information as to how much square footage they cover, so just be aware of the size of your room(s) in order to compare properly. Room size works vertically as well; if your rooms have high ceilings, you may require a more powerful air purifier in order to be effective. For this reason, the clean air delivery rate (CADR), which measures the cubic feet of air filtered every minute, is usually included in the specifications of each product.
Maintenance
Air purifiers are a fairly low maintenance appliance. In order to keep these machines running at peak performance, your primary task will be to keep the filters clean and replace them when necessary. The best air purifiers will provide some kind of indication that filters need to be replaced, so there is no need to obsessively check them.
The primary downside on the maintenance side of things, is that HEPA and activated carbon filters will need replacing many times per year. This is a recurring cost, as well a bit of a chore. Luckily, most pre-filters included in each appliance are washable, and a vacuum or cloth are all that it takes to make them good as new.
Because maintenance is required semi-regularly, access of filters is something to look out for. Ideally you can access your filters without moving the air purifier itself around.
Conclusion
Overall, air purifiers are an incredibly helpful appliance, particularly if you suffer from allergies or have a sensitivity to odors or other airborne particles. Because this is such an important appliance, there are many things to consider when shopping for one. Being aware of your needs and room specifications is crucial to finding the most effective appliance. Additionally, knowing the filters and their functions, as well as the maintenance involved can help give you a better idea of what life with each air purifier will be like. Hopefully this guide provides a good starting point for your search.
