That is why we have compiled the following list of the best air purifiers for extra-large rooms that are more than 1200 square feet in size. Considering that only the best large-capacity air purifiers made the top 3, take a look at what we discovered.

Best for Overnight: Alen BreatheSmart 75i Air Purifier

Alen BreatheSmart 75i Air Purifier

It is the most powerful air purifier in the BreatheSmart lineup, with a coverage area of up to 1,300 square feet, making it the most versatile. However, despite having the greatest room coverage, it only consumes 45watts when in use, making it the second lowest power draw in the BreatheSmart class. It also has the longest filter life, requiring replacement every 12 to 15 months. It is the most expensive. As most air purifier filters need to be replaced every 6 months, this will result in significant savings over time.
The BreatheSmart 75i is available in eight different colour options, including the standard black and white, as well as faux-wood finishes in maple, oak, and rosewood, among other options.

Using a True HEPA H13 filter, this will capture 99.99 percent of all contaminants larger than.1 microns, which is an extremely high rate. Dust, dander, allergens, pet fur, and a variety of odours are all examples of what can be found here. This model includes a laser Smart Sensor that detects airborne particles and a colour changing panel that automatically adjusts to show you the air quality in your home, providing you with greater assurance that it is cleaning your air. Each level has a different colour and will be displayed in a range from Blue to Red.

The power to clean a 1300 square foot room every 30 minutes would be expected to be quite loud, as would the noise generated by this. It does, however, have a very quiet fan, with noise levels ranging from 25 dB to 49 dB. In addition to being ideal for overnight use, the low fan speed generates “pink noise,” which has been shown to aid in the promotion of more restful sleep.

Pros
  • Cleans up to 1300 square feet
  • Very quiet at only 25dB
  • Great for overnight use, fan sound is “pink noise” which promotes restful sleep
  • Only draws 45watts
  • Filters last 12-15 months
  • 8 color options
  • Has an Air-Quality Sensor
Cons
  • Does not have a remote control or phone app

The Results of the Trial


We put the BreatheSmart 75i through its paces in a three-car garage that smelled like must and mildew. There was a noticeable difference in the smell after it had been left running overnight. We played it at the slowest possible speed, and the sound faded quickly into the background. The use of this would be excellent for overnight use in a bedroom. Aside from providing peace of mind, having the air-quality sensor was also beneficial.

Best Value: Coway Airmega 300 Air Purifier

Coway Airmega 300 Air Purifier

In spite of its small size, this air purifier packs a powerful 3-stage filtration system that provides the most powerful cleaning power of any air purifier on our list. This air purifier is capable of filtering a room up to 1,256 square feet and will remove up to 99.999 percent of airborne particles as small as.01 microns in size. That is ten times smaller than the majority of air purifiers you will find on the market.

They are able to achieve such remarkable results by combining the Coway Green True HELA filter with the Coway Activated Carbon filter. The HEPA filter removes harmful gases, volatile organic compounds (VOCs), dust, pet hair, dander, allergens, mould, viruses, and bacteria from the air you breathe.

The use of a clean filter is ensured by the presence of an air filter indicator that indicates when the filter should be replaced. Coway Airmega 300 also includes real-time air quality monitoring, which is accomplished through the use of a pollution sensor and a 4-color system, allowing you to easily determine the level of air pollution in your home.

The Auto-Mode feature will automatically adjust the fan speed in accordance with the current air quality in the room, saving you time and money. This will help you save money on operating costs while also extending the life of your filters. Furthermore, a sleep mode reduces the fan speed to its lowest setting, filtering the air without disturbing you while you’re trying to sleep.

The noise level produced by this device is comparable to that of the other devices on our list, ranging between 22dB and 52dB on average, depending on fan speed.

The Results of the Trial


When we were hit by two consecutive wildfires in our area in the span of two months, we decided it was time to invest in an air purifier. The room in which we left the Coway Airmega was 800 square feet in size and was completely closed off from the rest of the house. Wildfire smoke permeated the air, and after running the machine on high for an hour, the smell was completely gone. Using auto-mode, we can now let the device decide what the best fan setting is for the situation. Normally, it stays between a 2 and a 3, with our air quality always being in the blue, unless we leave the front door open for an extended period of time.

Pros
  • Warranty covers malfunctions for a year and electrical problems for 5 years
  • Has an air-quality sensor
  • Auto-mode and sleep-mode reduce costs with automatic fan settings
  • Removes air contaminants as small as .001 microns
Cons
  • This model is not WI-FI or phone app enabled and does not have a remote
  • Replacement filters are expensive

Best Performance: IQAir HealthPro Compact Air Purifier

IQAir HealthPro Compact Air Purifier

A more compact version of the HealthPro Plus, the IQAir HealthPro Compact is an excellent addition to our list of compact air purifiers. With a weight of only 25 pounds and dimensions of 24 inches tall by 16 inches wide, this is a device that is particularly useful for those who have a limited amount of available workspace. Although it is smaller than the HealthPro Plus, it uses the same HyperHEPA filter, with the exception of the odour and smoke trapping V5 Cell filter, which is not included in the compact version.

Using the IQAir exclusive HyperHEPA filter, this will trap ultra fine particles as small as.003 microns, allowing you to breathe cleaner air. Pet hair and dander, mould, allergens, dust, bacteria, and viruses are all covered under this policy. This is an excellent device for people who suffer from asthma and allergies, and it has received numerous 5-star reviews from people who claim that it has completely alleviated their symptoms.

While most air purifiers use a standard HEPA filter, the IQAir models use a HyperHEPA filter, which performs 100 times better than conventional HEPA filters. This model, which is known to promote better quality sleep, less snoring, and cleaner air, is slightly less expensive than the HealthPro Plus. As a result of its small size, it is easier to move around the house, especially when using the integrated handle.

The Results of the Trial


Anyone suffering from allergies will find themselves becoming best friends with the IQAir HealthPro Compact. This air purifier makes a remarkable difference in how you feel when you’re outside and how you feel when you’re in a room with this air purifier. Within a few hours, we were all able to take a deep breath again, with no itchy eyes or sneezing. It was not difficult to move it around the house due to its light weight and compact design. If it weren’t for the fact that it’s such an expensive (but absolutely worthwhile) investment, we’d buy two, one for each floor. Because it is quite noisy at higher fan speeds, we allowed it to run for a few hours at its maximum speed before switching to fan levels 1 and 3. When the noise reaches these levels, it simply fades into the background and ceases to be noticeable.

Pros
  • Lighter and smaller
  • The frame is very well built
  • Powerful fan
Cons
  • Expensive filter replacements
  • Higher fan levels are too loud for prolonged use

WHERE SHOULD I SETUP MY AIR PURIFICATION SYSTEM?
Make certain that it has at least 6 inches of clearance on all sides from any wall or obstruction before putting it in place. As a result, maximum efficiency and effectiveness will be achieved because airflow will not be restricted.

What is the average time it takes for an air purifier to clean a room?
After only a half hour, the majority of models show a discernible improvement. Nevertheless, some require two hours of continuous operation.
