Best Air Purifiers for 1200 sq ft: 6 Important Considerations!
Before making a purchase decision, there are several factors to consider in choosing the best air purifier for a space as large as 1200 square feet. It will help you find the right product that meets your needs and requirements.

Let’s take a look at some of the most important highlights:
Filtration (Air Quality)
Without proper filtration (absence of activated carbon filter), air purifiers are unable to capture and remove pollutants. This can lead to health issues for you and your family. The first and most important feature to consider is the air quality.
Not all air purifiers are created equal, and it’s crucial to look at the type of filtration system the purifier offers. These are the things that you should look for:
- Filter Types
- Efficiency
- Replacement Frequency
Ionizer
Ionizers are a popular feature found in many air purifiers today.
- They work by releasing negatively charged ions into the air, which attach to and neutralize positively charged particles such as dust and bacteria.
- The air quality is massively improved and there is also a reduction in the number of harmful particles floating around.
Coverage
It is an essential factor to consider before choosing the best large room air purifier that must not be ignored at any cost.
- Air purifiers are designed to clean the air in a specific area, and it’s important to choose one that can effectively cover the size of the room.
- An air purifier with inadequate coverage will not be able to clean the air in the entire room, leaving certain areas with poor air quality.

On the other hand, an air purifier with excessive coverage may not be as energy-efficient and can end up being more expensive than necessary.
Automatic/ Smart mode
An air purifier needs a smart or automatic mode to maintain a consistently clean and healthy environment without requiring manual adjustments.
- By constantly monitoring the air and making necessary adjustments, it can ensure clean air.
- Conserving energy is another advantage of using the automatic or smart mode in an air purifier.
- It only runs when needed, resulting in lower energy bills and a more eco-friendly home.
- It also helps to prolong the life of the air purifier and its filters by avoiding unnecessary use.

CADR Rating
Choosing an air purifier with an appropriate CADR rating is crucial. The air purifier’s ability to filter the air quickly and effectively depends on its CADR rating, which measures the volume of clean air it can deliver in a specific time frame.
- A higher rating means better air purifier performance.
- It’s essential to consider the size of the room where it will be used and choose an air purifier with an appropriate CADR rating.
- Select an air purifier with the appropriate CADR rating that matches the specific room’s square footage.

Noise Level
Air purifiers with high noise levels can be distracting and disrupt activities like reading or sleeping.
- It’s essential to choose an air purifier with a low noise level (32dB), especially if it will be used in a personal space or another quiet area.
- By considering the noise level, you can ensure that the air purifier will not be a source of annoyance or frustration.
- It is important to note that noise levels can vary based on the speed or setting of the air purifier.
So, make sure to first test the noise level in different settings before making a final decision.
