7 Best Air Purifier For 1200 Sq Ft in 2023

Do you have a large space that needs clean air, but are having trouble finding an air purifier that effectively cleans the air? If so, you are not alone. 

Most air purifiers available on the US market today are not efficient in cleaning spaces larger than 1200 sq. ft. due to their low CADR rating. 

CADR, or Clean Air Delivery Rate, is measured in CFM (cubic feet per minute) and indicates how much of the air has been cleaned of certain airborne pollutants, known as Particulate Matter (PM2.5), which can be captured by HEPA air filters. 

Additionally, some manufacturers exaggerate the real CADR rating and put the airflow number in specs. To assist you in selecting the best air purifier for your needs, we have compiled a list of the top air purifiers for 1200 sq. ft. rooms, homes, basements, offices, and other spaces. 

This article provides guidance on key considerations, expert and user reviews, and features to help you make an informed decision. 

Choosing a reliable and effective air purifier can ensure maximum air cleaning capabilities, allowing you to breathe easy in your large space.

List of Best Air Purifiers For 1200 Sq Ft

We have personally used and extensively researched the IQAir HealthPro Compact air purifier, and we can confidently say that it is an exceptional air purifier with many benefits.

One of the key benefits of the IQAir HealthPro Compact is its ability to clean a room up to 1,200 square feet, making it ideal for extra-large rooms or any other space of that size. 

The device has a powerful filtration process, which includes a HyperHEPA filter that can capture even the smallest particles, including viruses and bacteria.

The device is well-built with the highest quality materials, and it comes with a 5-year warranty. Additionally, the IQAir HealthPro Compact is made in Switzerland and features 3D Ultra Seal technology, which prevents polluted air from escaping the device.

The IQAir HealthPro Compact is also impressively quiet, despite its remarkable technology and fan power. The device has a bottom-to-top air flow structure, which allows for faster air cleaning in 1200 sq. ft. rooms.

One of the drawbacks of the IQAir HealthPro Compact is that it is heavier than other compact air purifiers, and it does not have an activated carbon filter. However, these drawbacks do not compromise its performance in any way.

The IQAir HealthPro Compact takes inspiration from the HealthPro Plus and GC MultiGas models, but it is cheaper than these models. It is a flagship model and offers more performance than expected, making it a good choice for price-conscious, brand-neutral buyers.

The Blueair Classic 605 and AIRMEGA 400S are alternative air purifiers in the same price range, but they do not have the same room coverage as the IQAir HealthPro Compact. The Alen BreatheSmart 75i is an air purifier with a lifetime warranty, but it is not as powerful as the IQAir HealthPro Compact.

The IQAir HealthPro Compact has evolved from previous models, and it shares the same design and structure as the HealthPro Plus. The device is made of stainless steel and has the option of four wheels or casters.

Overall, we consider the IQAir HealthPro Compact to be the best air purifier for 1200 sq ft rooms. It is a well-designed and high-quality product that delivers clean air in spaces of 1200+ square feet.

Our research and analysis have shown that the Alen BreatheSmart 75i is a top-of-the-line air purifier that offers exceptional performance and unparalleled customer service.

One of the standout features of this air purifier is its ability to filter a room up to 1,200 square feet, delivering clean air in spaces of 1200 sq. ft. or more. It does this through its 3-stage air cleaning system, which includes a True HEPA filter that can capture 99.97% of as small as 0.3 microns pollutant particles. 

This means that the device can remove even the smallest bacteria like E. Coli and Staph Bacteria from the air.

The Alen BreatheSmart 75i also comes with four air filter variants: Pure, Fresh, Pet, and Heavy Odor. 

The Fresh filter has an addition of Activated Carbon filter to deal with household odors and chemicals, while the Pet filter uses Alen’s patented Molecular Conversion Powder to ensure heavy pet odors are destroyed at a molecular level. 

The Heavy Odor filter can remove household odors from smelly kids/teenagers, kitchen garbage, and other everyday activities. The device also has a mesh pre-filter to capture large particles and extend the life of the True HEPA filter.

The air flow system of the Alen BreatheSmart 75i is bottom-to-top with a big air filter behind the front panel. Although the air flow is not as good as the 360 Degree air intake in other high-end devices, the device has an outlet air grill that looks different from the previous model. 

The device also has a modern control panel with the exact logo of Alen BreatheSmart 75i. The device is the heaviest in the line of Alen’s devices and weighs 27 lbs, but it comes with a useful handle to move it around.

In terms of its competition, the high-range market is mostly dominated by IQAir HealthPro Plus and Blueair Classic 605. However, the Alen BreatheSmart 75i sets itself apart from its competitors with its exceptional customer service and lifetime warranty. 

The device has evolved from previous models with a more robust construction, a bigger size, and a new plastic filter frame with detachable pre-filter for easy cleaning.

Overall, we highly recommend the Alen BreatheSmart 75i air purifier as the best air purifier for 1200 sq ft rooms. Its top-of-the-line performance, multiple filter options, and advanced features make it a great investment for those looking to improve their indoor air quality. 

With its lifetime warranty and 60-day satisfaction guarantee, the Alen BreatheSmart 75i is a reliable choice for anyone in need of faster air cleaning in 1200 sq. ft. rooms or larger spaces.

However, its size may be a drawback for some as it cannot be hidden from sight without disrupting its airflow.

The Shark HE601 uses a 3-in-1 filter that includes an anti-allergen HEPA filter. This filter is effective in capturing particulate pollutants but lacks odor removing qualities. The air purifier also comes with a range of available replacement filters that can be chosen based on specific needs. 

The default filter is the anti-allergen HEPA filter with an advanced lock that includes a honeycomb layer and carbon pellets to remove household odors. 

For added convenience, there is also the anti-allergen HEPA filter with advanced lock and fumes that can filter any kind of pollutants or allergens.

The air purifier also has Wi-Fi connectivity, which allows users to control the device remotely through an app. This feature is particularly convenient for people who want to monitor the air quality in their home or office from afar.

One of the drawbacks of the Airmega 300S is that it is slightly larger and heavier than the Airmega 300, which is the standard version of the same air purifier. This means that it cannot be moved around easily without casters, which is something to consider when deciding where to place the device.

Compared to its competitors, the Airmega 300S stands out for its ability to filter a room up to 1,200 square feet and its mid-range to high-range cost with premium features. It also has a stable and solid build that gives it a feeling of quality and reliability.

How to Choose Best Air Purifier for 1200 Square Feet

When it comes to buying an air purifier for a large room, like a 1200 sq ft space, there are several key features to consider to ensure optimal performance. Now, we will provide a buying guide to help you make an informed purchase.

Powerful Filtration System

The first and most important feature to consider is the filtration system. A powerful filtration system is necessary to effectively clean the air in a large room. One way to determine the effectiveness of a filtration system is by checking the Clean Air Delivery Rate (CADR) ratings. 

The higher the CADR rating, the better the machine can clean the air. However, it’s important to ensure that the CADR rating is appropriate for the size of your room. For a 1200 sq ft room, a machine with a CADR rating of 600 is recommended.

Activated Carbon Filter

An activated carbon filter is another important feature to consider when purchasing an air purifier for a large room. It helps to remove harmful chemicals and pollutants from the air, which can cause health problems. 

This filter is also useful in reducing unpleasant odors in the room, especially if you have pets or someone in the family who smokes.

Ionizer

While not necessary, an ionizer can be helpful in reducing the number of airborne particles in the room. It works by emitting negative ions, which attach to the particles and make them heavier, causing them to settle on the ground rather than float in the air.

Budget

Of course, budget is always an important consideration. There are many options available, so it’s possible to find an air purifier that fits within your price range. 

However, it’s important not to sacrifice quality for price. Investing in a good quality air purifier is an investment in your health, and it’s worth spending a little extra to get a machine that will perform well.

Coverage Area

The most crucial consideration when purchasing an air purifier is its coverage area. It’s important to buy a purifier that can effectively clear the air in your room size. Purchasing a smaller air purifier that cannot handle a 1200 sq ft room would be a waste of money.

CADR

The CADR or Clean Air Delivery Rate is the rate at which an air purifier can filter out pollutants, bacteria, and other harmful particles. A higher CADR means that the air is cleaned faster and more effectively. 

Therefore, it’s essential to choose an air purifier with a high CADR rating to clean the air in a short amount of time.

Size and Design

Finally, it’s important to consider the size and design of the air purifier. Large air purifiers can be quite substantial in size, so it’s critical to double-check their dimensions to ensure that they will fit in your space. 

Additionally, choosing an air purifier with a stylish design can enhance the aesthetics of your home or office, so it’s worth considering how it will complement your surroundings.

How Much Square Footage Does An Air Purifier Cover?

They come in various sizes and specifications, and it’s important to select the right size that suits your specific needs. 

Air purifiers are designed to filter the air in a specific area, usually a room or home. The size of the air purifier is crucial in determining how much square footage it can cover.

The coverage area of an air purifier is measured in square footage, and it’s essential to choose an air purifier that covers the specific area where it will be used. 

A small air purifier can cover up to 100 square feet, while a larger unit can cover up to 1200 square feet or more. When selecting an air purifier, consider the size of the unit and the specific needs of your home.

The size of an air purifier is measured in CADR (clean air delivery rate). CADR is divided into three categories: tobacco smoke, pollen, and dust. The CADR is the amount of filtered air that an air purifier produces every minute. 

To find the right size air purifier, look for an air purifier with a CADR rating that meets or exceeds the square footage of the room you want to use it in.

When choosing an air purifier, it’s important to consider the specific needs of your home. For example, if you have allergies, pets, or smokers in your household, you may need an air purifier with a higher CADR rating to effectively remove these airborne contaminants from your indoor air. 

The CADR rating should exceed the room size for optimal performance. Higher CADR ratings indicate better performance in removing airborne particles.

Research the square footage of the room and the specific needs of your home before selecting an air purifier. Choosing the right size air purifier for your needs can help you breathe easier and enjoy cleaner, healthier indoor air. 

The size of the air purifier and the CADR rating are crucial factors in determining the performance and effectiveness of the air purifier.

Final Words

When it comes to choosing the best air purifier for a 1200 sq ft room, two options stand out: the IQAir HealthPro Compact and the Alen BreatheSmart 75i. Both air purifiers are capable of cleaning a coverage area of up to 1200 square feet, making them ideal for extra-large rooms. 

The IQAir HealthPro Compact offers a powerful filtration process that captures even the smallest particles, including viruses and bacteria. 

On the other hand, the Alen BreatheSmart 75i features a 3-stage air cleaning system with a True HEPA filter that can capture 99.97% of particles as small as 0.3 microns, including bacteria. 

Ultimately, the best air purifier for your 1200 sq ft room will depend on your specific needs and preferences, but these two options are definitely worth considering.
