Keeping our homes and living spaces clean is important, but the pollutants and germs we can’t see are just as important as the ones we can see. You might consider your home pretty neat, but anyone can still be exposed to pollutants that, when left unchecked, can potentially cause harm to your body, from smoke to odors and other airborne particles. That’s where the best air purifiers for large rooms can come in handy. Here’s what you need to know to find the best air purifier for your home.

What Are the Benefits of an Air Purifier?

Air purifiers remove contaminants from the air with a circulating fan and filter. The fan pulls in the air in the room and pushes it through the filter, where all of the pollutants are then trapped, before expelling the clean air back out into the room. Some air purifiers, like those with a HEPA filter, are more equipped to trap allergens like pollen, dust, and mold, while others can remove denser particles from the air.

The best air purifiers for large rooms are usually outfitted with several filters, allowing them to eliminate multiple pollutants all at once. By consistently running your air purifier and keeping up with the maintenance, such as cleaning or replacing the filter or filters, you can ensure the air in your living space is as clean as possible.

The Best Air Purifier for Large Rooms

From the amount of space your air purifier can reach to how easy it is to maintain, there are a few factors you’ll want to look at before making your purchase.

Size and Coverage: Air purifiers come in many different shapes, sizes, and designs. But for a larger room or living space, you’ll want to invest in a larger device, as opposed to a smaller one intended to sit on a desk or smaller workspace. In this shopping guide, we selected only air purifiers for large rooms that can cover up to 600 feet or above.

Filter: Certain filters can handle certain pollutants. To get the most bang for your buck, invest in an air purifier that has a multi-stage filtration system, including both a HEPA and a carbon filter to not only eliminate dust, mold, and allergens, but any unpleasant odors as well.

Interface: You don’t want to buy an air purifier that’s going to keep you checking the user manual or running to Google to figure out how to use it. Invest in a device that’s relatively easy to use, with additional features to make the experience easier, whether you’re changing the fan speed, switching to night mode, or receiving updates about the air quality via your smartphone.

Maintenance: Be sure to look and see how much work will be needed to maintain your potential air purifier. For example, how often do the filters need to be replaced? Is there any additional cleaning that needs to be done? This becomes especially important if cost is a big factor in your decision-making process.

The Best Air Purifiers for Large Rooms

Below is our list of the best air purifiers for large rooms and living spaces.

1. Turonic PH950 HEPA Air Purifier 


This air purifier from Turonic is powerful enough to cleanse rooms up to 2,500 square feet in two hours. It comes equipped with several different filters: a mesh pre-filter, cotton filter, a true HEPA filter, an activated carbon and cold catalyst filter, as well as a humidifier. That might sound like a lot of man power, but the touch panel and remote control make switching between the eight different fan speeds and exploring all of its capabilities a breeze; automatic and night modes are also available for added ease so you don’t have to think too hard about which speed to choose.

You can also connect the device to your smartphone, in case you leave the remote in the other room or don’t feel like looking for it. There’s also a health indicator that provides readings of the air quality of the space the device is in; the light will turn green (perfect), blue (average), orange (not great), or red (terrible) to give you real-time updates.

Our product editors have tested and reviewed this air purifier for almost a month now, and immediately noticed the difference in air quality after the first week. There’s something to be said for having that peace of mind that the air we’re breathing is clean. We’ve noticed a huge change in seasonal allergy symptoms. Since regularly running the Turonic PH950, we’re not sneezing, itching, or blowing our nose as much as usual.

Coway makes some of the best smart air purifiers, and the 400S is designed to clean rooms up to 1560 square feet (for reference, bedrooms can be as small as 70 square feet) in just 30 minutes flat. Measuring 15 x 15 x 23 inches, the air purifier is compact enough that you can move it to different rooms — even up and down stairs — without any problem.

Coway says its powerful 3-stage filter (which includes a True HEPA and activated carbon filter) works to filter out 99.999% of particles 0.01-microns in the air, including pollen, pollutants and other allergens. It’s even powerful enough to filter out heavy smoke too, with some reviews reporting a “clean” room in as little as ten minutes, even in a large space.

The purifier has six speeds: smart, sleep, eco, low, medium and high, and its fan noise doesn’t distract. We’ve been able to sleep while the purifier was on its highest setting, and can tune it out on its lowest one with no problem. Using the smart mode puts the air purifier to work, as it will automatically detect the air and lighting conditions in your room to adjust settings accordingly.

You can use the IoCare mobile app to monitor your indoor and outdoor air quality, get notifications when you need to change the filter, schedule the machine, and control speed and smart mode. The Coway Airmega can activate with voice controls through Amazon Alexa, making it the smartest choice for high-traffic spaces of your home.
