If you’re like the 50 million Americans who have asthma or suffer from allergies and want relief, then you need an air purifier in your life. Air purifiers can help you breathe better and experience fewer asthma and allergy attacks.
Of course, with literally thousands of air purifiers on the market right now, we don’t blame you for not knowing which one to choose, especially if you have larger rooms in your home. That’s why we’ve put together this list of some of the top models that can help you rid your home of pollutants and dander. Read on for more information about the best HEPA air purifier for large rooms options on the market.
Large Room HEPA Air Purifier Reviews
Bissell Smart Purifier with HEPA & Carbon Filters
First on our list is this smart purifier from Bissell, which comes with both HEPA and carbon filters, and is specially designed to work in larger rooms. It’s excellent at cleansing your rooms of all kinds of pollutants, such as pet dander, smoke, pollen, and more.
Bissell’s smart purifier comes with a three-stage filtration system that provides you with the cleanest air possible. This three-stage system consists of a pre-filter, activated carbon filter, and an H13 HEPA filter that is designed to capture both large and fine particles, pet and home odors, as well as VOCs. Suffice it to say, there’s nothing that can escape the clutches of the Bissell HEPA purifier.
The medical-grade HEPA filter contained within the body of the Bissell captures a whopping 99.97% of particles that are as little as 0.3 microns small, even smaller, when on the lowest fan speed. This helps remove airborne irritants and allergens that can cause asthma and allergy attacks. The filter contains thousands of activated carbon pellets that are specially designed to capture volatile organic compounds – or VOCs – and common household odors.
The great thing about the Bissel purifier is that it has large room coverage and is AHAM certified. It can filter 1,252 square feet of space with one air change per hour, which is a lot more than most other air purifiers can handle. It also uses low energy and is extremely quiet, so you could even place it in a library if you wanted to.
It is Energy Star rated and comes equipped with five different fan speeds for you to choose from, the lowest of which is so quiet you won’t even hear it. The best part is the CirQulate system, which uses a VOC sensor to monitor indoor air quality and provide color-coded feedback while adjusting the fan speed to an appropriate level for continuous clean air.
The only problem with the Bissel is that replacements for the carbon filter can be tough to get your hands on.
- 3-stage filtration system
- Medical-grade HEPA filter
- Activated carbon filter
- Very quiet operation won’t disturb you
- Large room coverage
- Carbon filters can be difficult to replace
RabbitAir MinusA2 Ultra Quiet HEPA Air Purifier
Next on our list is the RabbitAir MinusA2 air purifier which, as the name suggests, is extremely stealthy. Its quiet nature means that you can leave it in your room overnight without disturbing your sleep, even if you have it in a higher setting.
Equipped with wireless capabilities, this air purification unit from RabbitAir allows you to monitor the quality of your home’s air and purify it no matter where you are, whether you’re lounging on the couch or are away from home. This allows you to enjoy an effortless clean air experience with the cutting-edge technology that RabbitAir includes in all of its products.
This purifier does not come with a typical HEPA air purifier, which traps contaminants and allergens, allowing them to accumulate on the filter and interfere with the machine’s efficiency. Instead, it features a BioGS HEPA filter that traps and reduces common allergens to support optimal filter efficiency while also prolonging the filter’s lifespan. It traps particles that are 0.3 microns in size with a 99.97% efficiency rating.
The great thing about the RabbitAir MinusA2 air purifier is that it comes in a range of different options. The standard versions come in black and white variants and WiFi-enabled versions come in the same color. What’s more, there are four purification models to choose from – Germ Defense, Odor Remover, Pet Allergy, and Toxin Absorber.
RabbitAir’s Germ Defense filter effectively traps and reduces airborne bacteria, spores, and mold that can carry viruses.
The Odor Remover filter traps and reduces odors from pets, tobacco, cooking, and mildew. Opting for the Pet Allergy filter allows the machine to trap and reduce pet odor and dander. The Toxin absorber filter traps and reduces VOCs and other harmful chemicals.
One of the only significant drawbacks that we see with this purifier is that you have to choose one specialized filter, so you won’t be able to experience the benefits of all at the same time.
- Wireless capabilities
- Advanced HEPA filter
- Various options available
- Prolonged filter lifespan
- Specialized filters
- Can only have one specialized filter at a time
IQAir HealthPro Plus Air Purifier
Next up is the IQAir HealthPro air purifier, which features a medical-grade H14 HEPA filter for purifying the air in your largest rooms. It’s definitely one of the largest purifiers on this list, and if you’ve got the means, it can be a fantastic option for your larger rooms.
IQAir’s patented HyperHEPA filtration technology is capable of trapping ultrafine particles as small as 0.003 microns, which is 10-times smaller than a virus. Independent testing has also verified that the IQAir HyperHEPA filtration system can trap at least 99.5% of all particles, providing your home with unparalleled protection against fine and ultrafine particles, including viruses and bacteria.
This air purifier features triple-seal technology, eliminating air leakage thanks to the filter media that is sealed into the filter frame. 3D UltraSeal technology is used to seal the filter frame perfectly to the housing, while individual seals ensure that everything is completely airtight. This means that not a molecule of air is going to escape, providing you with pure, clean air.
IQAir also included a completely new fan into this purifier, which can deliver an impressive 300 CFM while only using 27 watts of power at its lowest speed. At its highest speed, the fan uses 215 watts, which is still relatively low, helping keep your power bill on budget while still having clean air.
You’ll find an EvenFlow diffuser that provides 320° air delivery with no noisy air outlets or annoying draft. This provides you with total quiet comfort and super clean air while still being able to enjoy the quiet comfort of your home at night when it’s time to sleep. There are sophisticated controls such as programmable operating options, filter life monitoring, and color-coded lights to indicate when it’s time to change the filter.
This takes all of the guesswork out of maintaining your purifier and makes owning one of these machines a walk in the park. The only real gripe we have with the IQAir purifier is that it’s quite expensive, making it unsuitable for those working on a budget.
- Traps ultrafine particles
- Triple-seal technology
- Low power usage
- No noisy outlets
- Easy to maintain
- Expensive compared to similar options
Blueair Classic 680i Air Purifier
This compact and simple air purifier from Blueair is next, and it’s the perfect option for anyone who’s looking for an air purifier that will get the job done without any clunky, unnecessary features. It comes in a range of different size options, so you’ll be able to choose the one that best suits your room size.
Blueair’s Classic 680i air purifier offers you complete control with the Blueair Friend app, which allows you to monitor your air quality in real-time. Not only that, but the app gives you the option to adjust the fan speed to suit your room or set the whole purifier to auto mode to allow the machine to do all of the work for you.
What’s more, you’re even able to set a timer to suit your schedule, including scheduling night mode where your purifier will emit no light and be quieter than a whisper, allowing you to get a good night’s sleep. The great thing about Blueair Classic air purifiers is that they’re made from a durable steel body, built to stand the test of time. Don’t worry about having to replace this machine any time soon.
Blueair was sure to include an intuitive design on this purifier to make it as easy to use as possible. Using the simple control panel, you’re able to select from three different fan speeds, while a filter change indicator on the panel will let you know when it’s time to change your filter. The great thing about this purifier is that it uses dual protection filters with activated coconut carbon to naturally remove smoke and gaseous pollutants without the need for chemical additives.
It’s also WiFi-enabled, which means that once you’ve hooked the machine up to your WiFi network, you’ll be able to control it from anywhere inside and outside of your home, providing the utmost level of convenience.
Unfortunately, the blue LED lights on the control panel are pretty bright, which can be quite distracting in your darkened room. Other than that, we have no gripes with this machine.
- Real-time air quality monitoring
- Scheduling function
- Durable steel body
- Intuitive design is easy to operate
- 3 different fan speeds
- Blue LEDs are quite bright in dark rooms
Coway Airmega 400 Smart Air Purifier
Finally, we have the Coway Airmega 400 purifier, the most affordable option on this list. It’s an excellent choice for anyone who’s working on a budget, as it provides all of the features you’d need from a purifier without being overly expensive.
The Airmega 400 does an excellent job of cleaning the air and is a wonderfully quiet machine. When it is on its low setting, the only way you’ll be able to tell that it’s running is by putting your hand over the air vent to feel the breeze – from just 4 feet away, the machine is quieter than a computer. It’s even quieter than the average conversation when you crank the fan up to the high setting.
When the purifier’s pollution sensors recognize pollutants in the air, the LED changes from blue to red, and the fan picks up speed, working to cleanse the air of any pollutants. The great thing about the Airmega 400 is that it’s Energy Star-certified and it also features a Smart mode. When activated, this mode will automatically stop after not detecting pollution for more than 10 minutes.
If it detects pollutants again, it will startup automatically until it detects good air quality again, helping you save massively on your electric bills. The cleaning and maintenance of the Airmega 400 is a super simple process. The filter indicator will tell you when to clean the pre-filters, which is a straightforward process and will only need to be done every two weeks.
As for the machine’s appearance, the Airmega 400 is available in white and graphite/silver, so you can pick one that best suits your personal taste and style. The unit is 25 pounds, so it’s not ideal for lugging around the house, but it does come with handles at each side if you want to move it around.
While the initial investment in this purifier is cheaper than others on the market, its maintenance can be a little expensive since the replacement filters cost around $50. However, you only have to place the filters once a year, so this shouldn’t be a significant problem.
- Very quiet operation
- Large coverage area
- Great energy efficiency
- Saves money on power bills
- Attractive design
- Can be pricey to maintain
If you have large rooms in your home that you want to keep pure and clean, be sure to get your hands on one of the HEPA air purifiers mentioned above. They’re excellent for making sure that the air in your home is always safe to breathe.
