Are the air purifiers necessary? We don’t think so!
But in some cases they are required. For example, areas with poor air quality, densely populated office areas, or indoors with poor air circulation.
Energy efficient windows and doors are good at keeping pollutants out of your home, but they also trap in a lot of bad stuff.
According to the Environmental Protection Agency(About EPA), the concentration of some pollutants is often two to five times higher indoors than outdoors.
A good air purifier can reduce some pollutants and help you breathe more easily.
When we evaluate air purifiers, we mainly test their price, quality and efficiency (how much bacteria they claim to absorb).
In the end, we got this list of Top5 lists.
5 Best Air Purifiers 2019:
1. Coway AP-1512HH Mighty
One of the keys to Coway’s performance is its manufacturing quality, especially the close cooperation of its pre-filter and HEPA filter.
The pre-filter traps large particles, such as pet hair and fluff, which would otherwise block the HEPA filter and reduce its ability to trap fine particles.
At the same time, HEPA filters can be tightly mounted in Coway’s frame and tightly sealed in a plastic housing.
This prevents air from bypassing the edge filter and ensures that almost all air drawn from the machine is HEPA filtered, a design that is likely to contribute to Coway’s excellent performance.
In addition, Coway has many other features that make it easy to use, which is very important for devices that usually run 24 hours a day and are located in the bedroom, game room or living room.
Finally, Coway can maintain its excellent performance for a long time: we have repeatedly measured its performance for 2 consecutive years, and the effect is the same every time the air is purified.
2. Levoit Core 300
Levoit is currently the most popular air purifier brand in the United States. First of all, they have a lot of high-quality cheap air purifiers, and Levoit Core 300 is the latest device of 2019.
Secondly, they upgrade a new generation of air purifiers every year. The brand is building a very active air purification community.
Their latest product, Levoit Core 300, has an integrated air filter, which consists of the following elements:
- Pre-filter: This good preliminary filter is capable of capturing large particles of contaminants. You need to vacuum this filter regularly because it only works for a short time.
- HEPA filter: it can reduce 99.97% of down to 0.3 microns dust mites allergens, virus particles, pollen, bacteria particles.
- Activated carbon filter: It removes odors and smoke from your home.
There are not many certified HEPA air purifiers in this low-end market. Not only that, the performance of Levoit Core 300 is even 30% better than the previous Levoit LV-H132, and the price is almost the same.
If you have severe allergies and asthma problems, or you just want the best equipment you can afford, this air purifier is best for you.
3. Dyson Pure Cool
If the allergy season makes you live the worst life, then don’t be afraid: Dyson Pure Cool air purifier to save it all.
It can calculate the amount of pollutants in your home and then automatically adjust and filter them out.
When other air purifiers try to catch most allergens and pollutants, Dyson Pure has increased the bet, removing 99.97% of what makes you sneeze and tear.
Therefore, as long as you run Dyson Pure Cool for a period of time, allergies or other discomfort symptoms will obviously improve.
If you want to turn on the air purifier at night, Dyson Pure Cool’s night mode ensures that the purifier is quieter and its LCD screen is dark.
4. Rabbit Air MinusA2
Even after testing more air purifiers, the Rabbit air Minus A2 is one of the most worth buying air purifiers.
Rabbit Air is one of the leaders of American Airlines. Their Rabbit Air Minus A2 is the latest air purifier product and holds a significant share in the mid-range air purifier market.
In order to perfect this product, Rabbit Air has developed a 6-stage purification and deodorization system. Rabbit Air claims that it can produce the cleanest and freshest air in the world.
The ordinary air purifier uses only 2 to 4 filters to purify the air.
Rabbit Air MinusA2 uses not only one filter, but also double pre-filtering.
Most importantly, it improves the efficiency and life of MinusA2’s true HEPA filter, so it can last 2 years.
5. Blueair Blue Pure 211+ Air Purifier
Blueair Blue Pure 211+ air purifier has all the features of a purifier, and it is suitable for rooms below 540 square feet.
It draws in air from all directions, allowing the indoor air to circulate quickly and efficiently.
This process occurs five times per hour. This is a super energy-efficient product that consumes less electricity than a light bulb.
Activated carbon filters remove dust, odors, VOCs, gases, and other lung irritants, while particulate filters trap anything that may cause allergies or asthma symptoms.
In addition, you get two washable pre-filters that slide across the entire exterior of the device while adding a bit of fashion.
After investigation, we learned that most of the users of the device praised its efficient and quiet performance, but a few people said it was noisy.
Many air purifiers are decent. Vanishingly few are truly great.
But a great air purifier can really improve your life.
These machines are powerful enough to clean the air in a large living room or playroom, quiet and dark enough to sleep near in a bedroom, and inexpensive enough that it’s reasonable to have several spread throughout your home.

Can Air Purifiers Help?
The best way to improve indoor air quality is to remove sources of pollution and use clean outdoor air for ventilation.
Air purifiers, also known as air filters, are designed to filter the air in a single room, not the entire room like a HVAC system.
Although they do help reduce indoor pollution, their effects are limited.
Types of Air Purifiers
There are several technologies for air purifiers to address indoor pollution. Some products do better than others. But some products are actually harmful to your health.
- Mechanical filters: This is the type we tested. They used fans to force air through a dense network of fine fibers to trap particles. Can remove larger particles, including dust, pollen, and some mold spores suspended in the air (please pay attention to whether it is a true HEPA filter when buying).
- Activated carbon filters: Unlike mechanical filters, adsorbent filters use activated carbon to adsorb some odor molecules in the air. They may also handle some gases, but they are not particularly effective against formaldehyde, ammonia or nitrogen oxides.
- Ozone generators: These machines produce ozone, a molecule that can react with certain pollutants to change its chemical composition. This can lead to dangerous indoor air quality and we do not recommend them.
- Photocatalytic oxidation: PCO uses ultraviolet radiation and photocatalysts, such as titanium dioxide, to generate hydroxyl radicals that oxidize gaseous pollutants. Depending on the pollutant, this reaction sometimes produces harmful by-products such as ozone, formaldehyde, nitrogen dioxide, and carbon monoxide.
