Mismatching of air purifier and room size would see you literally waste your money. Even if you purchase the best air purifier for 1200 square feet, when placed in a 4000sqft room, its effectiveness becomes minimal. This is because of the mismatch; the room is much bigger than the air purifier.

This article is about on best air purifier reviews, helps you select the best product for your 1200sqft room. Getting down to business, the Coway Airmega 300 is just about everything that you need.

Room sizing and air filtration—what you should know

Room size is virtually the most important factor to put into consideration in air filtration. The larger a room, the more air it most likely contains, and the more the capacity of an air purifier that would be required to clean the air. Mismatching an air purifier and room size would see the air purifier become ineffective if its rating is smaller than the room you put it in.

Also, the larger the air purifier, the more expensive it would be and also potentially noisier too. Note that the capacity of an air purifier does not directly interpret into its cleaning effect. Its cleaning effect is completely dependent on the quality of the filter it possesses.

best air purifier for the price

Filtration

The three stages consist of a pre filter, true hepa filter, and activated carbon filter. The pre filter’s job is to prevent large particles in the air from getting into the unit by trapping them.

After this, the air then flows through the true hepa filter, removing 99.97% of 0.3 sized particles from the air.
Lastly, it flows through the carbon filter before it is released back into the atmosphere. The carbon filter removes gaseous contaminants in the air

Ion cluster technology

For further cleaning, this unit features an ion cluster technology along with its 3 stage filtration system. Ion cluster technology purifies your air at a microscopic level. It releases ions that bond with particles in the air, therefore making them too heavy and consequently falling off. Ion technology removes particles that might escape the HEPA and carbon filters.

Automatic mode and energy efficient

Automatic mode allows the air purifier to run in proportion to your needs. As your air quality gets poorer, the air purifier runs faster, and when the air gets cleaner, it drops in speed. In this mode, the unit both monitors the air and operates itself accordingly. According to the manufacturers, it is also energy efficient.

Air quality and filter replacement indicator

For a better user experience, this air purifier also displays your air’s immediate quality and tells you when it is time to replace its filters. This way, you do not have to worry about keeping yourself updated with those parameters, as they are easily known at a glance.

Capacity

Despite its good qualities, this air purifier falls below the 1200sqft capacity. According to its manufacturers, it should be used in a 1000sqft room size to work best. However, there remains a possibility that it works well in a 1200sqft room too.

best air purifier for the price

Filtration

This Bissell smart air purifier has a 3 stage air filtration system. The three stages consist of a pre filter, activated carbon filter, and hepa filter. When ran in its recommended room size, it does a good job of cleaning the air.

Its pre filter, like every other, is stationed at the outer portion of the unit. It is responsible for removing large sized particles and prolonging the life of the hepa and carbon filters. The carbon filter absorbs gaseous pollutants from the air as it flows through. It is effective against smoke, odors, and other harmful pollutants.

The last stage is its hepa filter. Like a standard hepa filter, this unit’s filter captures 99.97% of particles as small as 0.3 microns in the air. This way, it can confidently meet your domestic needs without much struggle.

Automated CirQulate mode

The automated CirQulate mode is just a fancy name for smart mode or automatic mode.

It also provides you with feedback on your air quality by default (whether it is running in the CirQulate mode or not).

Quiet operation

This air purifier is very quiet while operating. Quietness is not the most common of air purifiers because most of them need to use high capacity fans. Therefore, this quality puts it in the green light if you are on a tight budget.

Capacity

There is not much to say about the capacity of this unit. According to its manufacturers, it stands at 800sqft. Although that number may be good on a normal day, it is way below our 1200sqft consideration.

  • It is designed to filter the air in 800sqft room size once every hour, which is not up to our minimum 1200sqft

Factors to consider in choosing the Best air purifier for 1200 sq ft

Capacity: for this article, our recommended room size is 1200sqft; therefore, units with a low rating is a no go area. Although they might be cheaper, such a unit would lack enough capacity to properly humidify your air. The minimum recommended manufacturer capacity should be 1200sqft.

  • Filtration:

The stage of filtration and quality of filters used is an indication of how effective the unit would be. The air purifier must have a true hepa filter (or better) and an activated carbon filter. Other additions would also beneficial to you. The combination of a true hepa and a carbon filter is the best for dealing with household pollutants. You can also purchase air purifiers with additional filtration layers like ion cleaners and catalyst filters. All units have pre filters.

  • Automatic/ Smart mode:

This mode is there for your convenience. Instead of having to vary your air purifier speed every now and then as the air gets messy, you can simply run it in auto mode. In this mode, the air purifier takes charge and does both monitoring and speed change on your behalf. It makes the unit very convenient to use.

Air inlet and exit channels: firstly, air purifiers with their air outlet (after filtration) at their backside often have air circulation problems. Also, this kind of unit prevents you from placing the air purifier close to a wall. The unit you purchase should rather have its air outlet at the top, and we recommend that it has multiple air inlets too.

  • CADR rating:

The clean air delivery rate measures how quickly the air purifier would cycle the air in your room. The higher the CADR, the faster the air purifier would be in moving air, and consequentially cleaning your room.

  • Noise level:

Air purifiers must generate a certain level of noise because they require a powerful fan to work effectively. However, this sound level should be tolerable if you value your peace of mind. Avoid noisy air purifiers at all costs.

FAQs on the Best Air Purifier for Large Room Reviews

Is 1200 square feet a small house?

We wouldn’t exactly consider a 1200 square feet house small. But when you consider the fact that there are rooms as large as 1500sqft, then we can’t say 1200sqft is large either. Houses of this size are rather medium. However, when you consider it as a room, it is definitely in the large size category.

How many rooms can 1200 square feet make?

This depends on your design. There are rooms as small as 250sqft, and some even go down to 150sqft, although it is not standard. In a house of 1200sqft, you can conveniently make three rooms (if we evenly split it three ways; one sitting room and two bedrooms). Also, you can always play around with each room size to create more space for the other.

Do I need an air purifier for each of the rooms?

If the capacity of the air purifier is good enough, then no, you do not need an air purifier for each room. If you take our recommendation on purchasing the Coway Airmega 300, you can strategically place the unit in your 1200sqft home (the entrance doors open), and it would clean the air across all the rooms.

Can an air purifier be too big for a room?

Yes. An air purifier could be too big for a room when it is rated far above the room. This, however, does not have any negative effect on you or the room itself. The only downside is that you could have spent way less money on a unit that would still get the job done.

Asides from that, running bigger capacity air purifiers in a room even works much faster than an equivalent capacity unit.
In the end, it is always better to err on the side of caution and purchase a bigger air purifier than you need, rather than getting stuck with a smaller and ineffective one.

What is the best air purifier for a large room?

The best air purifier for a large room is the product that matches the capacity of the room. In a 6000sqft room (falls in the large category), the best air purifier would be a unit that is designed for room sizes of up to 6000sqft. In the case of this article, the best air purifier for 1200sqft would be the one that has a capacity of 1200sqft or more.
