Review: Best Air Purifiers
Indoor air pollution exists, and it can be the same - if not worse - compared to the air outdoors. For healthier air indoors, an air purifier is the easiest place to start. There are many air purifiers on the market offering different types of air purification, such as HEPA, ionization, UV, or a combination of purification types, along with additional filters to remove odors from the home. When looking for the best air purifier in 2021, take into consideration the amount of space the purifier is rated for, the type of purification it offers, the cost of replacement filters, and its ease of use.

Top Picks for Best Air Purifier
The Blue Pure 211+ has a three-tier particle and carbon filtering system which clears up to 99% of common airborne contaminants. The device boasts extremely low noise levels (32-56 dB, depending on the speed level). As the largest model offered by Blueair, the Blue Pure 211+ can filter air from spaces of about 540 square feet. This is wide enough to cover a large office, master bedroom, or family room. At around $300, the Blue Pure 211+ is a more expensive option comapred to others on this list, but it is certainly one of the best air purifiers money can buy.
Out of the plethora of affordable air purifiers on the market today, Okaysou's AirMax 8L caught our attention based on its features and capabilities. Though the external design takes no risks, it houses a total of 5 filters along with a large, vertically-aligned fan set directly against the filters for maximum output. The filter assemblies are separated into two distinct units - the first cartridge contains a pre-filter, HEPA filter, and an antimicrobial filter. The second cartridge carries a honeycomb-style activated carbon matrix for odor control, along with a cold catalyst mesh that neutralizes VOCs and airborne chemical substances. The lowest of the three fan speeds is whisper-quiet; even at the fastest setting, the AirMax 8L is no louder than a typical house fan. At $120, it's priced right too - the cheaper alternatives won't offer this much filtration or air circulation capacity, while higher performers cost three times as much. The 5-year warranty is unheard of in this category, though it requires registration to activate. For the money, there's nothing that comes close.
This compact tower model air purifier is suited for rooms of small-to-medium size. The Germ Guardian AC4825 uses a true HEPA filter to remove up to 99.97 percent of allergens commonly found in the air, while an activated carbon filter simultaneously reduces odors caused by cooking, smoking, and pets. A UV light effectively kills airborne viruses and bacteria, resulting in cleaner, fresher, and healthier air. This air purifier makes a noticeable difference in air quality while being quiet enough to be unobtrusive. Although the HEPA filter does need semi-regular replacement, it can be gently vacuumed to extend its life. For a smaller-to-medium space, this is an excellent choice.
Coway Air Purifier
Coway’s AP-1512HH air purifier remains one of the best purifiers on the market. In tests performed by other publications, it outperformed the competition costing twice as much when cleaning a roughly 300 sq-ft room. With a 3-stage filtration system (pre-filter, odor filter, and true HEPA filter) plus ionizer, it's easily capable of cleaning and recirculating the air in most spaces. On the top panel, an air quality indicator light shows you in real-time what the current air status is. Switch it over to auto mode, and it will clean the air when it senses pollution. The AP-1512HH also comes with a timer and Eco Mode; for the latter, the fan will shut off automatically if no indoor pollution is detected for 30 minutes, and will reactivate when it detects pollution again. Unfortunately the only downsides are the need to replace the odor and HEPA filters instead of being able to wash them, along with the lack of a dedicated low-light/noise night mode. Beyond the two minor downsides, the Coway AP-1512HH is the best air purifier overall on the market.
This best-selling model from Honeywell has a unique round design which allows for 360-degree airflow. This allows the 50250-S to be well-suited for use in large rooms, while still remaining relatively inexpensive to purchase. The 50250-S uses a true HEPA filter to remove up to 99.97 percent of allergens such as pet dander, dust, and pollen. The carbon pre-filter removes larger particles from the air, as well as reducing odors from sources such as smoking, pets, or cooking. This air purifier has three speeds to choose from, and a built-in filter life indicator to eliminate the guesswork in routine maintenance. The Honeywell 50250-S is capable of purifying air in a large space, is easy to maintain, and is an excellent value choice overall.
Mold, dust, pet dander, smoking, and other pollutants are all removed to 99.98 percent with the P500 air filter.

No matter how fancy-looking your home or apartment maybe, if it’s situated in an urban environment, it’s bound to build up dust and dirt over time. Even worse, you may even experience smoke getting in on a regular basis. With air pollution becoming more of a problem every year, it may be a good time to start investing in an air purifier for your home.
What is an air purifier?
Air purifiers do exactly what their name suggests - they purify the air. The way they do this varies on the type of filter and model used, but they essentially make the air you breathe cleaner and purer. Some purifiers are best-suited for cleaning out larger particles such as dust or smoke, whereas others are best used to get rid of harmful bacteria or viruses that may be floating around in the air.
Why do you need an air purifier?
Air purifiers are more useful than you think. They offer pragmatic health benefits that can really help out people with weak immune systems.
To keep your lungs healthy
One of the biggest contributors to lung-related diseases is smoke. But even if you don’t smoke cigarettes yourself, you can still develop lung problems related to smoking through what’s known as second-hand smoking. Second-hand smoking involves breathing in smoke without directly involving yourself with the smoke through activities such as cigarette smoking. Second-hand smoking is said to be even more deadly than first-hand smoking.
If you live in an area where smoke is more common than normal, you may want to purchase an air purifier. It cleans out the smoke particles in the air so you can breathe with peace of mind.
To prevent diseases
As mentioned earlier, there are certain filters used in air purifiers that can filter out bacteria and viruses. These days, viruses and bacteria are becoming more of a problem due to how easily they can spread. And some people aren’t born with the healthiest immune system, resulting in them receiving worse symptoms than normal. A dedicated air purifier at home can minimize the risk of bacteria and viruses spreading around the home, especially when combined with other safety rmeasures.
To breathe fresh air
Even if you don’t live in a smoke-ridden environment, it’s likely that you aren’t breathing fresh air, especially if you’re living in the city. Urban air is still full of small particles and impurities that make it very different from breathing fresh, pure air. An air purifier can turn your home into a safe haven for breathing, and your lungs will feel a lot lighter with no impurities in the air. It’s an almost therapeutic experience that anybody will enjoy.
Things to consider when buying an air purifier
Before you go and order the fanciest-looking air purifier online, here are a few tips to help you choose one that’s right for you.
The filter used in the air purifier is what does the purifying magic. As such, you’ll want to decide early on the type of filter that you want to use. Do you want to get rid of large particles such as smoke and dust in the air, or do you want to clean it of bacteria and micro-organisms that may get you sick?
Air purifiers aren’t exactly the smallest devices in the world. Sure, small air purifiers exist, but they’re only good for single rooms or small apartments. Bigger homes and larger rooms will benefit greatly from bigger and heavier air purifying devices, and that means you’ll need more space for it to fit in.
The best place for you to put an air purifier in would be by the window or any area where air might flow in. This will help instantly purify any air that tries to get inside your living space. Consider this and find space to put your air purifier by your window. If there isn’t any room by the window to put it in, try placing it as close to the window as possible instead.
Since you ideally want to use your air purifier as much as possible, you’ll want to consider the power usage as well. Some air purifier models are more energy-efficient, which can help you save up quite a bit over time. Of course, these types of devices don’t come cheap, so the upfront cost may be a bit greater, but it’s a worthy investment in the long run.
It’s good to know, however, that air purifiers generally don’t run on a lot of electricity. When compared to modern devices such as televisions and personal computers, air purifiers don’t use up nearly as much power, so you won’t have to worry too much about your electricity bill suddenly going up.
Air purifier price range
Regular-sized air purifiers can be bought for as little as $50. These air purifiers aren’t as big as more industrial-type models, but they are bigger than the small air purifiers that are best suited for portable use. More powerful and larger air purifiers, on the other hand, can cost you $200 or more, especially if they make use of high-quality filters.
How we choose the best air purifiers
Air purifiers are chosen based on the reviews that they receive, the type of material used, as well as the history of the purifier’s brand.
Do air purifiers work against COVID-19?
Air purifiers do work on viruses and bacteria, including COVID-19, but they aren’t enough to keep your home COVID-free, as they can also stay on solid surfaces. Consider employing other safety measures to keep the virus away from your living space. These include the use of alcohol and hand-washing to get rid of the virus from your hands and body.
Do air purifiers cost a lot of electricity to run?
Air purifiers, compared to other devices, run on far less electricity, so don’t expect too large of an uptick in your power bill even if you use it 24/7.
How big are air purifiers?
Depending on the model, some air purifiers can either be as large as a trolley or as small as a water tumbler.
