Best air purifier to buy in 2020 [Updated]

Picking the best air purifier for your needs may be hard if you are not expert with all that advanced technology. There are many different types of air purifiers on the market. Some of them use outdated old technology which still works and cleans the air, but the standard is moving to new advanced technology which can almost remove all air pollutants.

Best air Purifier to buy for home

Picking the right air purifier for your needs is not an easy thing because the needs of people are different. Someone needs a powerful air purifier for large rooms, and someone needs efficient small air purifier for a small room but capable of removing all pollutants.

Technology in air purifiers may be same, and everything may be equal, but the difference is in the brand. Some well-known brands use high-quality materials in making their product while others are looking to make affordable air purifier by using the not that high-quality material.

We are in 2020, and this air is purifying guide will help you make the best choice of the air purifier for your needs. We will talk about the best air purifiers in 2020. If you are buying one or you just want to educate yourself about air purifiers, We promise you that the following text will help you.

Why do I need an air purifier?

Pollution in the air is growing every day. The industry is polluting the air, and the air outside in big cities is not clean. You have probably seen news on the TV about big towns saying to people to stay inside and don’t come out if they don’t need to because the air is not at the best quality. These kinds of news will be standard in the future because the outside air is not getting better.

Because of that, the only thing you can do to breathe a really clean air is to stay at home and turn air purifier on. Air purifiers are capable of keeping the air at the high quality as long as the source of pollution is not present. That means you can close windows and with an air purifier enjoy the clean air in your home.

Many people don’t have problems by breathing bad air, but still, they need an air purifier for a bad smell. A good air purifier has powers to remove bad odors from your house. Because of that air purifiers are very welcome in the homes with pets. Some pets are cleaner than other, for example, a cat is a clean pet compared to a dog. But both of the pets will leave pet dander and urine marks which creates terrible odor in the room. To remove that smell you need to open windows or turn on an air purifier with the ability to remove bad odors. An air purifier can remove bad odors in very short time. Offices, shops and other places where people hang can really use an air purifier with the power to remove bad smell.

You should check if your location has clean air. You can do that by visiting this link:

Here you can see the level of pollution at your location and as well around it. If you are in the polluted area, then you need an air purifier. But even if you are not in the polluted zone it is wise to have an air purifier because these maps are not updated in real time. It is possible that your city maybe gets occasional pollution which may not be measured by the map. But if you are in the polluted zone then you better keep your windows shut and have a strong air purifier or few of them for every room. That is the only way to keep your lungs clean.

What is the best air purifier in 2020?

Technology is advancing and what is best in 2020 is better than the years before. And in this buying guide we are not only focusing on the best air purifier that is out there on the market, but instead, we will focus on the best air purifiers in each category. We will talk about best affordable air purifier, best high-end purifiers, best air purifier for smoke, best air purifier for pets, best air purifier for the car, best air purifier for mold, best air purifier for allergies, best air purifier for a large room and best air purifier for a small room. As you see, we will cover all the sections of the interest. If you don’t find all the needed information on this page, then you are probably looking for something that is not yet made.

Filter Types

There are many different types of filters in modern air purifiers of the year 2020. Most of them are combined in same air purifier because each of the filter is used for a different kind of pollution. HEPA filters are becoming standard, and in 2020 it is wise to look for the filter that is having HEPA certificate.

Ionic filtration is something that is not yet fully safe because of the possibility to emit ozone. But I am sure in near future we will be able to use ion generators without fear of too high levels of ozone in the room.

Charcoal or Active Carbon filters are must have in each air purifier. These filters will remove bad odor from the room. And some strong and large active carbon filters even have the power to remove gases, chemicals and other toxins from the air.

HEPA vs. True HEPA Filters

Both of these filters work on the same principle. They remove a high percentage of airborne particles from the air. But the difference between them is in the price and efficiency.

True HEPA filters are expensive, but for that money, you are getting an air purifier which can filter 99.97% of the airborne particles. True HEPA filters need to be certified and tested, and when you are buying an air purifier, you should read somewhere in the description exact percentage of the efficiency.

Regular HEPA filters are working on the same principle but they are not tested, and the effective power is around 80 to 90% of removing all airborne particles. The difference is not huge considering the numbers, but knowing that the nastiest pollutants are extremely small, you should aim for the True HEPA filter.

best affordable

Best Affordable Air Purifiers

Money is one of the limitations to many people. If you can not afford high-end air purifier, then you just need to buy the best air purifier for the money you have. Thankfully there are many of those on the market, and you can really pick the best one out of many. These affordable air purifiers will do the job, but maybe they will struggle if you put them in too polluted rooms or too large rooms. Because of that read the manual before buying.

Hamilton Beach

Hamilton Beach is one of the most affordable air purifiers on the market. For the low money, you can get HEPA grade filter in this air purifier that is capable of removing 99% of the airborne particles. You need to know that this air purifier has HEPA graded filter and not True HEPA filter with a certificate. But because of that, it is on the affordable list. The air purifier has three speeds, and you can use it vertically or horizontally, and because of that, it can fit any room, any desk, and any office. One more good news for this affordable air purifier is the filter which is permanent. That means you will not need to buy new filters every year and because of that maintenance cost for Hamilton Beach air purifier are low.

Best Air Purifier For Car

Best Air Purifier for Car

An air purifier for the car is a device that will keep your car fresh. There is no need for a whole air purification system with carbon filters, HEPA filters or whatever. You can bring fresh air to the car by opening all windows. But if the bad smell is already in the car and is strong and caught on seats then only opening windows won’t help you much. Then the only solution is to clean your car with deep cleaning or turn on the air purifier.

You need to be careful with this kind of negative ion generators because they produce ozone. Even if it says on the device that is not producing ozone, you must know that the technology behind it work may produce ozone after all. Because of that, I suggest leaving ion generator to work while you are outside the car. Once it is done just open car doors for some time and your car will have utterly fresh air.

FRiEQ Car Air

FRiEQ is one of the manufacturers that made an exciting and easy to use air purifier for the car. This device is extremely affordable, and everyone should have one.

Best Air Purifier For Large Room

Best Air Purifier for Large Room

For a large room, you will need a sturdy air purifier. I have already mentioned few of the powerful ones that can be good for the large rooms. Simply for the large room, you will need large size air purifier with the large ventilation system. It should have large HEPA filter because if it has a small HEPA filter, then that filter may get dirty too fast. And for odor removing active carbon filter needs to be large enough to cover the whole room. Why buy two small air purifiers if you can have one large and powerful to remove all unwanted things from the air on its own.

You only need to plug it in the wall, and air purifier will work from the there. It will take zero space in the room.

GG1000 is using UV-C technology to remove airborne particles, and there are no filters. That means you will not need to spend extra cash for replacement filters. But there are some concerns that UV-C light cannot remove all airborne particles and is not effective like the True HEPA filters. This may be true, but for a small room, this model can be enough.

GG1000 will not only remove bacteria, viruses, mold spores and other things that can be removed with UV-C light technology, but it will also remove odor, smoke and other bad smells from your small room.

What to Consider When Buying an Air Purifier

By reading this list, you are one step closer to the best air purifier for your needs. But you should consider some stuff before you make the ultimate decision. You need to think about various things:

Room Size

Room size is critical when you are buying an air purifier. Some air purifiers are just too small and too weak for large rooms, and some of the big and powerful air purifiers will just be overkill if you have a small room. Because of that you always need to know what room you have and then search for the air purifier that fits closely to your room size. All of the air purifiers have a label that says for what size of the room they are a perfect choice.


Not many air purifiers have the power to remove allergens. Some of them will just remove the bigger ones, and the small ones like mold spores or even pollen may go away, and you will still have allergic reactions. Because of that if you truly need an ultimate air purifier against allergens then you need to buy the most expensive device on the market. That device is used as a professional device, and some hospitals use this kind of air purifiers. They use patented HEPA filters which cost lots of money. But if you are in need of that the money should not be limiting factor.


Some air purifiers need lots of maintenance, and some of them will require a handyman to do the maintenance, and this only brings more cost to your pocket. When you are picking the air purifier you need to consider these elements as well; maybe it is better to add more cash at the initial buying than to spend every few months additional money on keeping the air purifier clean and at the best performance. All True HEPA filters need to be replaced with time, some of them last longer and some of them last shorter but in the end, you will need to replace them if you wish to have an air purifier that is working at maximum velocity.

Also, there are air purifiers without HEPA filters, I mentioned some of them on the list, and they have zero maintenance costs because they don’t need filter replacement. Maybe you will need to wipe them here and there, but that is all.

Filter Type

We always recommend to the buyers to buy an air purifier with True HEPA filter or the patented HEPA filtration systems. I know these air purifiers are costing more than the conventional HEPA grade filters air purifiers, but you will, in the end, have a 100% working air purifier instead of always having the question on your mind if the air purifier is actually working.

Other than HEPA filters there are electrostatic systems and ion generators. Both f these systems are good to use, and they will do a good job in cleaning the air in the room, but they are not even close to the True HEPA filters or even to the HEPA graded filters.

Features and Options

You should always consider these offers because some fancy option which you maybe don’t need may lift the air purifier price and that is not the best buying tactic then. You should carefully consider what you get for the money you pay. There are many features that air purifying companies offer. For example, consider a fan type, do you need strong ventilation system or maybe the fans need to be as silent as possible, it will all depend on the room. For a sleeping room, you should look for low noise fans. Some air purifying companies offer android apps which are great for the people that use smartphones, but if you are not using a smartphone or you have trouble with using it, then you should definitely look an air purifier without this option. You should also consider about the indicators on the air purifier, the ones that only have a button to turn it on and off are of course more affordable than the ones with the real time air pollution level indicator. But I still recommend an air purifier with filter indicator. This feature is very handy when you need to replace the filter, and with that indicator, you will know when air purifier needs replacement, and you will never replace the filters blindly or too late.
