Wirecutter Best Air Purifier On The Market Of 2022

If you are looking to buy an air purifier, don’t miss the following buying guide.

Many people suffer from respiratory problems, generally derived from allergies and asthma. These reactions and diseases are usually caused by the environment: how it is, what load it carries, temperature, pollution, etc.

H till a few years ago we had to resign to accept the conditions imposed by nature itself, which is also responsible for controlling the atmosphere that reigned in our homes. We spend 90% of our time in closed spaces, so challenging it and controlling the particles suspended inside these spaces is practically indispensable for people suffering from allergies and asthma.

Those responsible for leaving the interior of the rooms of a home pristine are air purifiers. They are a kind of robots, more or less autonomous, that is connected to the electrical outlet are capable of quantifying and manipulating – to the point of eliminating or eradicating – the dirt from the environment that reigns in the room in which they are found.

Buying Guide to Choose The Best Wirecutter Air Purifier

Wirecutter Best Air Purifier in living room

What Air Purifier Should I Buy?

Well, as with everything, there are certain considerations that you should not ignore. On the one hand, we have the part that only affects the air purifier, while on the other there is our real need. We do not have to make the mistake of thinking that because it is more expensive, an air purifier will solve the ballot better than another that costs half; We highly recommend making a deep and sincere reflection on where we are going to use the appliance –which rooms or rooms-, when we are going to do it –at what time of day- and for what purpose –yes, cleaning, but there are levels and levels.

The Importance of The Stay

When we buy an air purifier, we can see that one of its specifications is that of cleaning capacity. It is given in square or cubic meters, depending on the brand. This data indicates the maximum size –in surface area or volume, respectively- of the room to be cleaned so that the result is optimal; that is to say, unbeatable according to the characteristics of the purifier. Cleaning the environment of a 12 square meter room is not the same as that of an 80 square meter room. It makes sense, doesn’t it?

The Importance of Power

The power of an air purifier is closely related to its capacity. The more power we have, the faster it will clean the air in the room of the size indicated by the specifications. If the purifier is located in a larger room, the power will be less relevant data, since although it takes longer to carry out its task, it will not be to leave the perfect room, but to leave it as clean as possible.

If the air purifier is instead located inside a room that is smaller than the instructions dictate, the power can be lowered to do the same job it would do in a larger room: clean the environment thoroughly. The reduction in power entails a reduction in the consumption of light, so it is a fact that we have to take into account without fail, especially in these times.

Suitable Dimensions

What dimensions are suitable? With air purifiers, it happens that, as a general rule, the bigger they are, the more work capacity they usually have. It is not a determining factor in evaluating the quality of an air purifier, but it is in regard to the decoration of our house and the comfort of transportation since sometimes air purifiers exceed 60 centimeters in height and it is completely impossible to camouflage them.

In addition, the larger they are, logic dictates that they will weigh more, making their transfer more difficult. As it is a sophisticated device that entails a certain economic cost for the interested party, the usual thing is that there is one per house, especially if it is of a medium or high range. For this reason, what the person in charge does is move it from one room to another, since even if we leave the air purifier in one room and have all the interior doors of the house open, it will purify the room where it is especially well., while the others will hardly notice the effect. They may get to do it, but it will not be like in the “origin” room. For all these reasons it is necessary to take into account its physical characteristics.


The filter to an air purifier is like an engine to your car. It is what marks its quality, although so far there is not a huge variety as it happens with car engines. The filter par excellence for air purifiers is HEPA. We have to be careful when we read the characteristics provided by advertisers since they often try to confuse us without crossing the line of illegality or fraudulent advertising by saying that the air purifier has a HEPA filter when what we really want is a HEPA filter. That “type” HEPA is not the same, and they say it in terms of effectiveness, which is relatively similar. But for a filter to be HEPA, It must comply with standards previously established by the competent organization, which are none other than trapping, with 99.97% effectiveness, all particles equal to or greater than 0.3 microns. This is the acronym, which comes from the English expression High Efficiency Particulate Air.

As a general rule, what makes an air purifier be considered low-end or mid-range – and high, naturally – is the possession of such a filter. If it is HEPA, we will find a substantial increase in price and, obviously, in the quality of air cleaning. If it is not, the alarms do not have to go off, because the cleaning results can be more than satisfactory for our purposes. On many occasions we are not interested in paying for this type of filter; hence it is so necessary to make a sincere reflection prior to the purchase.


Virtually all models have different operating speeds built in. They serve to regulate how quickly we want our air purifier to act. We usually find ourselves with night mode, with turbo mode, and with intermediate modes. We will not say anything about the intermediates because their name says it all. From the nocturnal, comment that in theory, the purifier works at a minimum performance, drastically reducing – as the theory indicates – noise that it generates normally. This noise can be heard at its peak when choosing the turbo mode, with which the device maximizes its performance and filters the air as quickly as possible. We usually use it if we are in a hurry or for situations in which an inordinate amount of dust enters us through the window that we did not expect when having it open.

Ionizing Function

The ionizing function is also usually present in almost all air purifiers, although there are some low-end that still do not have it. What it does is emanate negatively charged ions, which through chemical bonds bind to positive particles generated by electromagnetic devices, normally the most harmful to our health. With the union, heavier elements are formed, which fall to the ground and cease to be a danger for us, especially for the little ones. They disappear when we do the general cleaning of the house.

Active Carbon Layer

The active carbon layer is responsible for eliminating odoriferous particles. The carbon in this filter is treated with oxygen, which causes the opening of many pores between its atoms. These pores, when the molecules are released, act as absorbents and are responsible for the disappearance of odors, some gases, and liquid pollutants from the environment.


And here we come to one of the key points of this guide. It is what is going to determine how annoying an air purifier is, without a doubt. Before buying anything from ourselves, we have to be clear that an air purifier is a mechanical machine, so it will forcefully emit noise. How many? We will have to see it in the specifications and try to inform us by other means if it is high or low data for what we are willing to support.

Inside the market, air purifiers that boast of being noise-free typically don’t go below 30 decibels. We say this as a guide or reference, since this amount may be too high for someone and too low for someone else. One aspect to consider is whether we intend to have the air purifier connected in our bedroom while we are sleeping. If we are very light sleepers we can have problems when it comes to staying asleep, so it is very convenient to consider operating hours. The night mode of the purifiers does not have to deceive us, because the only difference with the standard power is that the noise is partially reduced, but not completely eliminated at all. If you have ever bought an air conditioner, you will know what we are talking about.

The Programing

Curiously, not all devices have a function as simple a priori as programming in advance. It seems to us a most useful application when we have decided to sleep with the air purifier on, as well as when we want the environment to be clean when we get home from work. What we achieve with programming is to tell you when to turn it off without us going to press the button. It is not a determining function to measure the quality of the purifier, since, as we say, there are those that have it and there are those that do not, the fact that the device is low-end, medium, or high-end is indifferent.

Autonomy – The Best of The Best

This is the item that only high-end air purifiers have. It is extremely comfortable because it allows the device to work independently without having to worry about the electricity bill.

The air purifiers autonomous have some sensors capable of measuring dirt in the environment, and inform through some visual element -Lights led, normalmente- the quality of the air. If we activate the independent mode, it acts according to what its indicator marks. It turns on more power, less, consumes more energy, saves, works to the maximum, relaxes for a while … make the right decisions, and the icing on the cake comes when the sunlight begins to go down. The device captures the photons emitted by the star king and identifies if it is dusk, dawn or if you are at a time when the sun is shining like never before. If you decide that it is night, the device is put to a minimum performance, even turning off the led lights so that they do not interfere with our sleep. Being a high-end air purifier, its default night mode is usually quieter than other purifiers, making it easier than ever to sleep with it plugged in.

Other Additional Items

The ones we have just seen are the most typical elements of air purifiers that we can find on the market. In addition to these, we can come across others that can also be decisive when setting the price. This is the case of the remote control, for example: comfortable as possible, although unnecessary depending on in which cases. So are the device openings; that is, where it expels the air. The capacity of cubic meters of filtered air per hour is also often an important indicator of quality and therefore price. Finally, we will have to realize that the finishes will be another factor that, without altering the operation of the purifier in the least, can cause it to skyrocket in price by presenting a more elegant and sophisticated design.

We hope this air purifier buying guide has been useful to you. Feel free to contact us or leave us a comment below if you need more help.

Criteria for Buying a Purifier According to The OCU

According to the Organization of Consumers and Users (OCU), the most efficient purifiers are those that have a HEPA filter, since they are the only ones capable of removing 99.97% of particles down to 0.3 microns.

In especially delicate spaces, such as kitchens, dental clinics, or hospitals, it is advisable to combine the HEPA filter with negative ionization to prevent the appearance and reproduction of fungi and bacteria.

Right on the other side is UV air purifiers, which the OCU defines as “unnecessary and potentially dangerous.”

Purifier Use Guide

Baby Air Purifier is it Harmful?

As you may have already seen, there are many air purifiers that can be found on the market.

While it is true that in principle none should be harmful to babies, it is also true that the safest are those that use a True HEPA filter and an activated carbon filter.

For Allergies And Asthma

The wirecutter best air purifiers for people with allergies or asthma are those that do not use UV or ions and are also ozone free.

To Sleep, is it Suitable?

Yes. Air purifiers are designed to be used in closed rooms during sleeping hours.

In the event that you are a light sleeper, we recommend buying an air purifier that emits no more than 25 dB.

Disadvantages of Air Purifiers

The main drawbacks of air purifiers are:

  • Not all air purifiers are equally effective at neutralizing pollutants.
  • Very few models have the ability to completely renew the air in the room in which they are placed.
  • A good number of models are too loud to sleep next to them.

Frequently Asked Questions To Choose The Wirecutter Best Air Purifier

1. What is Better a Humidifier or an Air Purifier?

These 2 types of products are used to treat air, but their functions are completely different.

Humidifiers are only responsible for regulating the humidity level in dry environments, while purifiers filter and return clean air of pollutants that can be harmful to health.

Therefore, depending on what you need for your home, you will have to decide between a humidifier or a purifier since they are products that, although they may seem similar, have a very different use.

2. How Much Does an Air Purifier With a HEPA Filter Consume?

The consumption of an air purifier depends on the power that each different model has, but in general, it is a very small consumption that will not even be noticed on the electricity bill.

In addition, its consumption is higher when it works at maximum speed and that happens at times when the air is highly loaded with pollutants, but this process does not usually take more than 15/20 minutes.

In normal situations, it is kept at a minimum speed and therefore consumption is very low.

3. Is an Air Purifier Useful to Combat Covid-19?

An air purifier cleans pollutants that are in the air and also removes odors, but by itself, it is not useful to fight the Covid-19 virus.

It can be a supplement that helps, but at no time can it replace the rest of the preventive measures that must be taken against this virus, since what is known about it so far is that it is spread by contact.

4. Are There Air Purifiers For Cars?

Yes, there are currently quite a few different models of car air purifiers.

These models are characterized by being small in size and being able to connect to the cigarette lighter or to a USB.

Even though they are very small, these mini purifiers are highly effective in cleaning pollutants that can be found in the air inside a vehicle (dust, pollen, mites, gases, etc.).
