I Tested And Reviewed 10 Best Air Purifier For Large Rooms (2023)

After extensive research and consideration, I finally found the perfect air purifier that exceeded my expectations. Upon a friend's recommendation, I decided to give the Levoit air purifier a try, and I couldn't be happier with my choice.

First and foremost, this air purifier operates quietly, providing a peaceful white noise that I find soothing even on higher speeds. It's a great addition to my bedroom, as it ensures a tranquil environment for a good night's sleep. Additionally, accessing and cleaning the filters is a breeze, especially with the cleanable filter that saves me the hassle of constantly buying new ones.

In terms of performance, the Levoit air purifier does an exceptional job at its primary function. As a pet owner with three furry dogs and frequent visitors, I needed a purifier that could effectively tackle the constant shedding and potential allergens. This device exceeded my expectations, effectively removing pet hair and dander from the air.

One aspect I did overlook initially was the importance of regular filter cleaning. Neglecting this maintenance can lead to the second filter becoming dirty, which unfortunately cannot be cleaned. So, it's crucial to establish a routine for filter cleaning to avoid frequent replacements.

The design of this air purifier is also worth mentioning. Its unique airflow system, which draws air in through a continuous slot at the bottom and up both sides, ensures efficient purification throughout the room. Additionally, the device offers various cool features that I haven't fully explored yet, as I'm already highly satisfied with its basic functionality.

In terms of odor elimination, I was initially skeptical about the effectiveness of air purifiers. However, the Levoit air purifier proved me wrong. As a foster cat owner, I constantly battled with the unpleasant smell of litter boxes. Despite my daily cleaning routine, the scent lingered. Upon further research, I discovered that the Levoit air purifier was highly recommended for combating animal smells. I decided to give it a try, and to my delight, the cat smell vanished within 12 hours of continuous use. The auto mode feature, which increases the speed in response to impurities in the air, was particularly effective when the cats used the litter box.

I have been using these air purifier units for quite some time now, and I must say, they have exceeded my expectations. They are still performing exceptionally well, and I am even considering purchasing another one. These units have significantly minimized the dust in my house, and my home always smells fresh. The continuous air circulation feature of these units ensures that the air is constantly filtered, providing me with clean and purified air. I highly recommend these air purifiers.

Moreover, I have set up auto delivery for the filters, which arrive every three months without any hassle. This ensures that I never have to worry about replacing the filters manually, and it keeps the air purifiers running efficiently.

I did come across a minor issue initially, but I quickly figured out the solution. After changing the filter, the machine needs to be reset. To reset it, you simply need to hold down the button on top for 10 seconds, and it will clear the filter change notification.

In terms of performance, these units have been running flawlessly 24/7. They truly live up to their promise of cleaning the air effectively. I regularly change the gray stretch filter, and when the red light indicates that it's time to change the white corrugated filter, I replace it promptly. However, I did encounter a small issue when changing the white filter on one occasion. The red light did not turn blue as it usually does. Although I had changed this filter before without any problems, I am unsure of what caused this issue. I have included pictures for reference.

Before purchasing these air purifiers, I conducted extensive research and read numerous reviews. This model consistently appeared among the top three air purifiers of 2018. After further investigation and reading, I decided to give it a try. I purchased two units of the 411 model, which were delivered on January 9, 2019. I immediately put them to work, and on the first day itself, I noticed a significant difference in the air quality. I have attached a picture of the units on the first day, and I will provide further updates as the filters begin to show signs of use.

The operation of these units is simple and user-friendly. With just a touch of a button on top, you can choose from three speeds – low, medium, and high. The low and medium speeds are extremely quiet, while the high speed is slightly noticeable. I personally prefer running the high speed during the day and switching to low or medium at night for a quieter sleep. The compact size of these units makes them easy to move around from room to room. In fact, I even placed one unit in my office area for the day, and it effectively reduced the dust on my desk shelving.

After using these air purifiers for a month, I have noticed that the filters do not seem to be accumulating much dirt. However, the stretchy filter on the outside of the units does collect a significant amount of dust and requires regular washing. Despite this observation, I have not noticed any visible dirt being drawn into the main filter. I will continue to monitor this and provide further updates.

I recently purchased an air purifier for my common area and larger room/hallway, and I am extremely satisfied with its performance. This air purifier is perfect for my active family, as we have a dog that sheds regularly and we are constantly going in and out after hiking or running. Additionally, I cook a lot, so having a good purifying function for dust and the ability to handle smoke purifying during forest fire season were essential for me.

The air purifier I chose not only met my must-have requirements but also exceeded my expectations. It effectively handles a big area, significantly reducing the dust in my home. Even with a robot vacuum running daily, my house used to be super dusty, but after using this air purifier, I noticed a significant reduction in dust, especially after adding two units – one on the main floor in the middle of the common area and one upstairs in the hallway.

Although I haven't tested its ability to handle smoke purifying during forest fire season yet, I am hopeful that it will perform well. The maintenance of this air purifier is relatively easy. The filters are all in one unit, with a thin pre-filter attached to the carbon and HEPA filter with Velcro. I vacuum the pre-filter every 3-7 days and have also tried washing it. However, I found that washing and drying the pre-filter changed its shape and tension, making it difficult to put back. As a solution, I decided to buy filter packs with extra pre-filters, which are readily available at a reasonable price. This allows me to replace the pre-filter more frequently, considering the dustiness of my house.

In terms of size, the air purifier is compact and doesn't take up much floor space, which is a great advantage for me, considering my open floor plan. Moreover, the white color of the unit effectively hides my white dog hair. While most people prefer quiet air purifiers, I actually appreciate a bit of noise. My dogs are sensitive to sounds outside the house, so I use the air purifiers as noise machines. The middle setting of the air purifier is perfect for maintaining clean air without being too loud during family socializing. However, when I know I will be receiving a milk delivery at night, I turn the setting to the highest level, along with a noise maker by the window closest to my milk cooler. This combination keeps my dogs from barking, and I find it very effective.

I recently purchased the Aroeves air purifier after having a negative experience with a different brand. Let me tell you, the difference is night and day! Within just a couple of hours of using the Aroeves air purifier, I noticed a significant improvement in the air quality in my bedroom, especially as a smoker.

As a smoker, I disliked having to go outside in the frigid temperatures, but I also didn't want my bedroom to smell like smoke. The Aroeves air purifier proved to be a game-changer. I ran an experiment and found that just 15 minutes after smoking, my daughter, who doesn't smoke, couldn't even tell. She described the air in my room as crisp, like when you walk outside on a cold day.

Not only does the Aroeves air purifier effectively remove smoke odor, but it also helps with other allergens and dander. I have three dogs, including a German Shepherd, which is known for having high dander levels. Before using the Aroeves air purifier, I experienced wheezing, puffy face, stuffy nose, and headaches. I was on inhalers, allergy medication, and even steroids. However, within an hour of using the Aroeves air purifier, I noticed a 100% improvement in my symptoms. No inhaler needed and I can breathe normally again.

I appreciate that the Aroeves air purifier comes in different sizes. I purchased the MK04 for downstairs and the smaller ones for the bedrooms. The setup and usage were easy, and the big unit even has a sensor that changes color based on air quality. The price is reasonable, and the noise level is acceptable to me.

While the Aroeves air purifier has greatly improved my air quality, it's important to note that it's not a fix-all solution. I still have to clean and vacuum regularly. I am also planning to change my dogs' diet to whole foods and raw to help with less dander and shedding.

The Jowset Air Purifier Model AP403 has exceeded my expectations and has become a valuable addition to my living space. Right from the unboxing experience, I was impressed with the compact packaging and the careful protection provided by foam inserts and clear plastic wrap. This ensured that the unit arrived in perfect condition.

Inside the package, I found the 24VDC power adapter, remote control, user manual, and warranty registration information card. The power adapter was thoughtfully wrapped in bubble wrap, providing an extra layer of protection during shipping. Installing the filter back into the unit was a simple process, requiring a quick clockwise turn. I recommend consulting the user manual to familiarize yourself with the control functions on the air purifier's top before starting to use it.

Registering the air purifier is highly recommended as it grants an additional year of warranty coverage, providing peace of mind for the user.

Setting up the air purifier was a breeze. All I had to do was plug the power adapter into a nearby wall outlet and connect the small end to the air purifier unit. By tapping the "power" button on the front control panel or using the remote, the unit started and went through a short cycle to assess the air quality and adjust its mode accordingly. The color indicator and PM2.5 count on the front panel provided real-time information about the air quality, and the fan speed adjusted automatically to optimize air purification.

Using the control panel or remote, I was able to adjust various settings, including the countdown timer ranging from 1 to 12 hours or continuous operation, fan speed options from 1 to 4 or automatic, and night mode for quieter operation in the bedroom. The "change filter" indicator served as a useful reminder to replace the H13 HEPA filter, which I recommend purchasing directly from Jowset for compatibility.

The air purifier also features a child lock, adding an extra layer of safety when young children are around, preventing accidental button presses.

Since incorporating the Jowset Air Purifier into my living space, I have noticed a significant improvement in air quality. The automatic mode efficiently maintains clean air, reducing my allergy symptoms. While not completely silent, the unit's sound is barely noticeable amidst other ambient noises in my home, easily blending into the background.

Considering its reasonable price and impressive performance, I am contemplating purchasing additional Jowset air purifiers for other areas of my home. Overall, I highly recommend the Jowset Air Purifier Model AP403 to anyone looking for cleaner indoor air and relief from allergy-related discomfort.

I recently purchased this air cleaner and I must say, it has exceeded my expectations. I have a medium-haired cat and a Shepard mix dog, so I wanted to ensure that my mom, who visited for the weekend, wouldn't be bothered by the hair and fur. Thankfully, she had no issues during her stay.

The filter is incredibly easy to check and after a couple of weeks of use, it still looks pretty good. The best part is that the air cleaner operates silently, except for when it's on Medium or High settings. I leave it on 24/7 and have noticed a significant improvement in air quality.

I highly recommend this air cleaner, especially considering its quality and the fact that it was on sale. Although it doesn't come with a remote, adjusting the settings is a breeze thanks to the high sensitivity buttons.

Another user also shared their positive experience with this air cleaner. They mentioned that it is incredibly quiet when running and has made a noticeable difference in the air quality of their home. With multiple cats and litter boxes, their house is prone to dust and dander, but the air cleaner has effectively cleared the air and improved the overall smell of their home.

They were so impressed with the results that they purchased a second unit for another room in their house. By running these two units, they have noticed a significant reduction in dust and have experienced easier breathing. According to them, the air cleaner is definitely worth the investment.

Another reviewer shared their concerns about air quality in their 1-bedroom apartment, particularly due to having two cats. They were pleased to find that the air cleaner effectively filters the air and operates quietly. They even included a picture to demonstrate the effectiveness of the filter on the lowest setting.

Lastly, a user mentioned that they had a mold issue in their home and used this air cleaner in other rooms to ensure safe air for their family. After two months of use, they checked the filter weekly and were pleased to find that the air test results showed an improvement in air quality. They initially had doubts but the results proved that this air cleaner is indeed effective.

I have been using the Honeywell Hepa Air Purifiers for almost 4 years now, and I am still amazed by their performance. I currently own three of these machines, having replaced all three of my round Honeywell air filters. With regular maintenance and filter changes, these air purifiers continue to do an excellent job of filtering the air in my home.

Even with two cats in my home and my asthma worsening with age, these Honeywell Hepa Air Filters have proven to be incredibly effective. The replacement filters are reasonably priced, and the machines operate silently, especially in the lowest setting.

– Tom F. from Chicago, IL

As someone who has struggled with chronic allergies and sinusitis, I have used HEPA air filters in every room of my home for the past 20 years. Among the various units I have owned, most of them manufactured by Honeywell, this particular unit stands out as the best and quietest air filter I have ever experienced.

Consumer Reports rates this air filter highly, and it's easy to see why. Not only is it affordable, but it also offers double filtration with an extra thick charcoal filter followed by an extra thick HEPA filter. The air is pulled in from the front of the unit, passes through both filters, and is then released through an air grate on the top of the unit, making it a space-saving option that can be placed anywhere, including against a wall.

With four levels of filtration, this air filter provides options for different needs. The first level, GERM, operates silently, making it perfect for watching movies. The second level, GENERAL CLEAN, produces a pleasant white noise while offering efficient filtration. The third and fourth levels, ALLERGEN and TURBO, provide superior air flow while remaining quieter than other Honeywell filters.

Although I still own multiple Honeywell filters and use them daily throughout my home, I plan to replace them with this unit as my budget allows. When searching for an air filter, I compared it to units priced as high as $600. After evaluating almost 20 different units and brands in the $200-$600 price range, considering Consumer Reports and Amazon consumer feedback, I was convinced that this Honeywell unit was the best choice. Its price, filtration method, attractive control panel, ability to be placed against a wall, compact size, and my positive experience with Honeywell products over the years made it the perfect fit.

I am extremely satisfied with my purchase of the Honeywell Hepa Air Purifier and highly recommend it to others. The ability to turn off the blue light on the control panel is also a welcome upgrade compared to my other Honeywell units. Thank you, Honeywell and Amazon, for providing such a reliable and efficient air purifier.

I recently had the opportunity to test this device against a larger and well-reviewed air purifier, the Coway Airmega. To my surprise, this device outperformed the Coway Airmega in terms of air filtration. I initially tested it in a small office with an AQI (Air Quality Index) of 70. Within minutes, it was able to reduce the AQI to 23. Impressed by its performance, I decided to move it to a small bedroom. Once again, it quickly improved the air quality, reducing the AQI from 50 to 6 and the PM2.5 levels from 25 to 1.5. I used a Temtop air quality tester, which displayed consistent readings with the iPhone weather app showing an AQI of 70 outside. Overall, this device proved to be highly effective in improving air quality within a short period of time.

Setting up this cleaner was a breeze. Contrary to the product description claiming it can clean a very large room, it is actually quite compact. However, it does not compromise on performance. I work in a hospital and have a large office space. I set it up on Monday and left it running on the #2 setting throughout the day and night. The noise level on this setting was minimal, and it didn't bother me at all. The high setting, on the other hand, was a bit loud, but I simply adjusted it to a lower setting. When I walked into my office the next morning, I immediately noticed the fresh smell in the air. The dust seemed to have dissipated, and the overall air quality felt cleaner. I'm hopeful that this unit will last a long time, although I did have some difficulty finding replacement filters. It claims to have a lifetime of 2000 hours, but I'm concerned that it might require a new filter sooner. However, given its affordable price, this machine is definitely worth considering. I'm also unsure if the blue light is functional or purely decorative.

On a side note, I did purchase an extended warranty from Amazon as I couldn't find a manufacturer's warranty. I will update if any issues arise. Despite this concern, based on my experience so far, I would give this device a 5-star rating. Its performance and effectiveness in improving air quality are impressive.

I have been on the hunt for a new air purifier for quite some time now, and after extensive research, I finally stumbled upon the Winix 5500-2. This unit ticks off all the boxes on my checklist – it's suitable for larger rooms, comes with an auto feature, has reasonably priced replacement filters, and boasts a sleek design that complements my home decor.

Upon receiving the unit, I was impressed with how quickly and easily I was able to set it up. The body of the purifier is made of a durable matte black plastic, giving it a sturdy feel. The front panel is easily removable, secured by a clever magnetic clasp that allows for easy access to the prefilter for regular cleaning and replacement of the hepa/carbon filters. The filters fit snugly inside the filter chamber and are held in place by the prefilter, which snaps firmly into place.

The control panel at the top of the unit is intuitive and user-friendly. The buttons are clearly labeled, and visual cues provide a clear understanding of the functions. A stylish indicator light bar runs along the bottom of the control panel, displaying the level of air cleanliness with a three-color scheme – green for clean, orange for okay, and red for bad. The purifier can be manually operated on four fan settings, or you can choose the auto mode, allowing the machine to adjust the settings based on the data collected from the sensor. This hands-off operation is a convenient feature. Additionally, there is a night mode that sets the fan to its lowest setting to reduce noise and dims all lights on the panel. The night mode is activated automatically when the unit is set to auto mode, as a light sensor detects the presence or absence of light in the room. The control panel also features a filter change indicator light, providing a convenient reminder for filter replacements. According to my research, the hepa filter should last approximately one year.

One of the standout features of this air purifier is its exceptional quietness. Even on the highest fan setting, it produces noise levels similar to that of a standing floor fan on high. This was a pleasant surprise, as it ensures a peaceful and undisturbed environment.

In terms of performance, the Winix 5500-2 effectively cleans the air. I have been using it in my 350 sq ft bedroom, and although I don't have the equipment to measure air changes per hour, the manufacturer's claim of at least four air changes per hour seems accurate. I have experienced no lingering smoke smell in the bedroom when running the purifier with the door closed. The difference in air quality between the bedroom and the rest of the house is noticeable after the first night of using the purifier.

I am more than satisfied with this air purifier, as it has exceeded my expectations and fulfilled all my requirements. In fact, I plan on purchasing two more units for my combined kitchen, dining, and living room area, which totals 700 sq ft. With proper placement, I am confident that these units will provide ample coverage. The Winix 5500-2 offers unbeatable value for its price, with low costs for replacement filters and a wide range of features.

Looking at the long-term durability of the purifier, I am happy to report that it has remained in excellent working condition over the years. I have owned it for two years, running it 24/7, often on the highest setting, and it shows no signs of wear. I recently purchased another unit for additional coverage, and after three years of constant use, it is still going strong. This durability is a testament to the quality of Winix's products.

It is worth noting that there have been claims of this device producing harmful amounts of ozone. However, after conducting my own research, I discovered that the Winix 5500-2, along with other devices from Winix, has been tested by the California Air Resource Board and is certified to produce under 0.050 ppm of ozone. This level falls within the safe range. I urge readers to conduct their own research and verify claims made in reviews, as misinformation can be rampant.

I recently purchased this air purifier for my office and I must say, I am extremely satisfied with its performance. I keep it running 24 hours a day to maintain a clean and dust-free environment, and it does a fantastic job. The photo I took during a recent filter change after 4 months clearly shows how many particles it captures, proving its effectiveness.

One of the standout features of this air purifier is its quiet operation. Even when running on high mode, the sound levels are minimal. I usually switch it to medium or low mode when I'm watching TV, and the noise doesn't disturb me at all. The sleep mode is practically silent, but I personally prefer the medium mode at night as it creates a soothing "white noise" that helps me relax.

I appreciate the option to set the running hours, as it automatically shuts down after the desired time. Additionally, the color band around the controls adds a nice touch. If you don't manually choose a color, it streams different colors, creating a pleasant visual effect.

In terms of design, this air purifier is compact and contemporary. It doesn't look tacky in any room and blends well with the decor. I do recommend placing it on a raised surface rather than on the floor for optimal performance.

Considering the price, which was on sale for $55.00, I believe I got great value for my money. I have been using it continuously for two weeks, and the change in color of the filter indicates that it is effectively eliminating dust and impurities. I couldn't be happier with its performance.

I was fortunate to stumble upon this air purifier when there was an additional $30 off coupon available, making the purchase even more affordable. It is not a large unit and fits perfectly just above the power outlet socket. I even provided a video demonstrating the three different speeds, which are all quiet and efficient.

Most importantly, this air purifier has greatly improved my allergy symptoms. After discovering black mold in my living space, I promptly removed it and ordered this air purifier. The difference has been remarkable. The air smells clean, and my nasal passages are clear. I have been sleeping soundly and experiencing relief from allergy symptoms throughout the day.
