Should You Buy An Air Purifier and How To Choose The Right One?

Have you decided to buy an air purifier? You've probably realized that you need it as you no longer want to think about what kind of air you breathe in your home. It doesn't matter what time of year it is, whether it's winter or summer, the necessity of this device is no longer in question. The quality of the air we breathe must be good, and an air purifier can meet all your needs. What you need to have in mind when buying is whether it will be enough for the surface of your home. We will show you how to make sure that the purifier you've chosen is suitable for the space you have.

Choosing the Right Capacity

The main thing to think about when buying this appliance is the quality of the filter and the ability of proper airflow. A quality device can clean almost 99% of all air pollutants, of course, depending on the types of filters it has. Before buying, it's very important to pay attention to how big surface a purifier can cover. It's good to know the square footage of the room in which the device will be located and decide on the best solution depending on its dimensions. This way you will avoid making two mistakes. If you plan to put the purifier in a small room, you will not need to buy a too strong and too large appliance that is intended for large rooms, which also costs more. If you intend to keep the appliance in a large room, you should not opt for a low-capacity purifier because you will not have a satisfactory effect. Air freshness will not be according to the standards and the air in that room will still be polluted, so in that case, you will be throwing your money away.

To avoid these errors, it is best to pay attention to the following factors:

The size of the room where the air needs to be purified
Purification capacity (cu ft/min) and (cu ft/h)
Air purification rate (CADR) cu ft/h
You will know based on these parameters whether an air purifier is suitable for the room for which you intended it. It's recommended that you find information on the recommended size of the room for a certain type of appliance, as well as the purification capacity, among the characteristics of the selected device.

What is CADR?

When choosing an air purifier, you need to pay attention to another detail - whether the device is marked CADR (Clean Air Delivery Rate). Most modern appliances have it, and thanks to this label, it will be easier for you to decide whether a certain purifier meets your needs. This mark indicates the capacity of the purified air. Simply, it shows you how much air inside a room of a certain size can a certain model of appliance purify. If a device has a very high filter efficiency, but low airflow, CADR helps to balance these two. CADR is measured when the air purifier is running at maximum fan speed. To measure the efficiency of removing particles of different sizes, three types of particles are tested - smoke, pollen, and dust.
Purifiers with this label are controlled by the Association of Home Appliance Manufacturers (AHAM). Products are randomly selected and independently tested to verify that they continue to meet the performance stated on the product. Another factor to consider is the ACH (Air Changes Per Hour) label. It shows how many times an air purifier can purify the air in a certain room in 60 minutes

The label is usually marked with 4x, 5x, and 6x. This means that a 6x label would represent that the air in the room is filtered 6 times in one hour. So, the higher this number, the higher the efficiency of the device. With the above-mentioned, it's clear how important it is for the selected device to be the right size and capacity - as such, it will provide you with reliable air purification at home, efficiency, and the results you expect. Therefore, depending on the size of the space where you plan to use the purifier, there are several different sizes of these appliances:

Small - suitable for smaller rooms and rooms up to 200-250 sq ft.
Medium - great for the space from 250 to 650 sq ft.
Large - for all rooms from 650 to 1200 sq ft.
Household purifiers - suitable for purifying the air in any room.

At, we offer a wide range of air purifiers, where you will find a large selection of these devices from various brands from all over the world. Most of them offer models intended for different sizes of rooms, so you have a chance to choose the one that will suit your needs.

Too Big or Too Small

As we've already mentioned, you should buy a purifier proportional to the size of the room for which it is intended in order to get the maximum effect. It should be neither bigger nor smaller than what you need - of course, smaller variations won't be making a huge difference. To purify the air in more rooms, add up the square footage of those rooms or simply decide on one of the rooms where you will use it. With upstairs houses, one appliance most likely won't be able to cover the entire space. If you want, we suggest that you consider separate units for each floor so that the effect is as you wanted. However, whether it’s an apartment or a house, it all depends on your space and, more importantly, the layout of the room. If it's divided into several units, it would be more efficient to have more devices - it's best to have a device in the rooms where you stay the most. Think about all these factors, consult and make the right choice.

Where to Place It?

When buying this appliance, there's another very important question - Where to place it in your home. If you have a portable device, you can move it depending on where you are and where you need it the most. However, if a purifier is larger and heavy or the one that hangs on the wall, it's recommended that you place it where you spend most of your time. Here are some options:

Kitchen and rooms - If your biggest problems are odors, then this is the right place for the device. It's known that the storage of food from the kitchen spreads various odors - if that bothers you, a kitchen is an ideal place for your purifier. However, be careful with a purifier in this room, due to the high degree of humidity in the air, higher power purifiers are recommended. If you have a problem with dust and the smell of your pet, then the living room is the ideal place for the appliance. In a situation where you want to breathe clean air while sleeping, put it in the bedroom. However, be careful to place it at least 2 meters away from your head, as air should not go directly into your face.
Odor source - For the best effect, the appliance should be placed near the odor source. That way, the odors will not spread to other rooms.
Entrance door - In case you have pets or the circulation of people is large, the best place for this device is near the front door. That way, the air purifier will have a protecting role as it will prevent the entry of dust and pollution.

Unlike these locations in the apartment, there are places where an air purifier should never be placed:

Corners - These appliances work best when they have free airflow. So never put them in tight spaces and corners because then they won't be as efficient.
Furniture - The space under or behind some piece of furniture is a very bad position for the appliance as an air purifier won’t be able to suck the air from the room and purify it. The effect will be almost the same as if you didn't have this appliance at all.
After all, there is another dilemma about the position of the device in someone's home. Whether to place it on the floor or it should be hung on the wall. The advice is to pay attention to the instructions for use. The manufacturer usually specifies the place where you can keep it. If it's advised to hang it on the wall and if its design lets you, do so because that way you will achieve maximum effect.
