6 Things To Consider Before Buying An Air Purifier

Air pollution is a growing concern that's affecting many people worldwide. The presence of pollutants like dust, smoke, and allergens in the air we breathe poses a threat to our health. Fortunately, air purifiers can help improve the air quality in our homes and offices. However, before buying an air purifier, it's crucial to consider several things. In this blog, we'll explore some key factors to keep in mind when making your purchase. By doing so, you'll be able to make an informed decision and enjoy the peace of mind that comes with knowing you've chosen the right air purifier for your health and well-being.

Types of Air Purifiers

Before buying an air purifier, you need to decide first what type of air purifiers are available in the market.

HEPA Air Purifiers

These air purifiers use a High-Efficiency Particulate Air (HEPA) filter to trap particles such as dust, pollen, and pet dander. They are effective in removing airborne allergens and pollutants from the air.

Activated Carbon Air Purifiers

These air purifiers use activated carbon filters to remove odors, smoke, and chemicals from the air. They are especially useful for people who have pets or smoke indoors.

UV-C Air Purifiers

These air purifiers use ultraviolet light to kill bacteria and viruses in the air. They are effective in reducing the spread of illnesses and can be especially helpful during cold and flu seasons.

Ionic Air Purifiers

These air purifiers use negatively charged ions to attract and remove particles from the air. They are effective in removing allergens and pollutants, but they can produce ozone, which can be harmful in large amounts.

Ozone Air Purifiers

These air purifiers generate ozone, which can help eliminate odors and kill bacteria and viruses. However, they can also produce harmful byproducts and are not recommended for use in homes with people or pets.

It's important to note that not all air purifiers are created equal, and some may be more effective than others at removing specific types of pollutants. When choosing an air purifier for your home, consider your specific needs and look for a product that is designed to address those needs.


Room Size and Placement

When buying an air purifier, it's important to consider the size of the room where you will be using it, as well as the placement of the purifier within the room.

Room size

The first thing you need to consider is the size of the room where you will be using the air purifier. Air purifiers are designed to filter the air in a specific size room, so you need to make sure you choose one that is designed for the size of your room. If the purifier is too small for the room, it will not effectively clean the air, and if it's too large, you may be wasting energy and money.


Once you've determined the appropriate size of air purifier for your room, you need to consider where you will place it. The best location for an air purifier is in a central location in the room, away from walls or furniture. This allows for the most efficient circulation of air and the best airflow through the purifier. It's also important to avoid placing the air purifier near any sources of heat or moisture, such as a radiator or humidifier, as this can affect its performance.

Filtration System

When choosing the best air purifier, consider its filtration system. Look for purifiers with HEPA filters, which can capture tiny particles like pollen and dust. Some purifiers also have activated carbon filters, which can remove odors and chemicals from the air. Make sure to check the size of the purifier and the room it can effectively clean.

Noise Level

When choosing an air purifier, it's important to consider the noise level it produces. Most air purifiers make some noise when they're running, but the amount of noise can vary widely. Some air purifiers produce a low humming sound, similar to a refrigerator or a fan. Others may produce a louder sound, more like a vacuum cleaner or a hair dryer. The noise level of an air purifier is typically measured in decibels (dB). A decibel is a unit used to measure sound intensity. The higher the dB level, the louder the sound.

When choosing an air purifier, you'll want to look for one with a noise level that's comfortable for you. If you plan to use the air purifier in a bedroom or other quiet space, you'll want to choose one with a low noise level, around 30 to 50 dB. If you plan to use it in a larger room or a noisy environment, a higher noise level, up to 70 dB, may be acceptable.

Keep in mind that some air purifiers have a "night mode" or "sleep mode" that reduces the noise level while still providing effective air purification. It's also a good idea to read reviews and check the manufacturer's specifications to get an idea of how noisy a particular air purifier is before making a purchase.


Energy Consumption

When buying an air purifier, it is important to take into account its energy consumption. Not only can this impact your monthly electricity bill, but it also affects the overall environmental impact of using the appliance.

One key factor to consider is the wattage of the air purifier. Generally, the higher the wattage, the more energy the appliance will consume. However, it is also important to consider the size of the room in which the air purifier will be used. A larger room will require a higher-wattage air purifier to effectively clean the air, while a smaller room can make do with a lower-wattage appliance.

Another consideration is the type of air purifier technology being used. Some technologies, such as HEPA filters, are more energy-efficient than others, such as ionizers. Some air purifiers may also have energy-saving modes or timers that can help lower the amount of energy they use overall.

Maintenance and Filter Replacement

When choosing an air purifier, it's important to think about how often the filter needs to be cleaned and replaced.


Maintenance refers to the tasks you need to perform to keep your air purifier working effectively. This may include cleaning the unit's exterior, checking the air filter for dirt and debris, and wiping down the fan blades. Most air purifiers come with an instruction manual that outlines the recommended maintenance schedule.

Filter Replacement

Filter replacement refers to the frequency with which you need to replace the air purifier's filter. Over time, air filters become clogged with pollutants and lose their effectiveness. To make sure that your air purifier is removing pollutants from the air well, you should change the filter regularly. Depending on the type of air purifier and what the manufacturer suggests, the time between replacements can vary.

When buying an air purifier, it's important to think about how easy it is to maintain and how often the filters need to be changed. This will help you choose a unit that will keep giving you clean air for years to come.

Frequently Asked Questions

Does the air purifier really work?

Yes, air purifiers can be effective in improving air quality by removing pollutants such as dust, pollen, smoke, and pet dander from the air. However, their effectiveness depends on several factors, such as the type and size of the purifier, the pollutants present in the air, and the size of the room. It is important to choose the right air purifier and use it correctly to get the best results.

Is it good to sleep with an air purifier?

Yes, it can be beneficial to sleep with an air purifier because it can help remove pollutants from the air, which can lead to better indoor air quality and may improve sleep quality for some people. However, it's important to choose an air purifier with a noise level that is comfortable for you and to make sure that it is properly maintained and cleaned to avoid any potential health risks.

Which is better, an air humidifier or a purifier?

Air humidifiers and air purifiers serve different purposes, so it's not a matter of one being better than the other. An air humidifier adds moisture to the air, which can be beneficial for people with respiratory problems, dry skin, or allergies. On the other hand, an air purifier is designed to remove pollutants and allergens from the air, which can improve indoor air quality and may be particularly helpful for people with asthma or allergies.

Do you need an air purifier if you have AC?

An air conditioner can help improve indoor air quality by reducing humidity and filtering out some particles, but it is not designed to disinfect the room and remove all pollutants from the air. If you are concerned about indoor air quality and have specific air quality concerns such as allergies, asthma, or living in a polluted area, an air purifier can be a useful addition to your AC system.

How many hours a day should you leave your air purifier on?

The number of hours you should leave your air purifier on each day depends on several factors, such as the type and size of the purifier, the level of pollutants in your environment, and your individual needs. 

As a general guideline, it's recommended to run your air purifier for at least a few hours each day, particularly during times when indoor air quality may be lower, such as during allergy season or when outdoor pollution levels are high. Many air purifiers have timers or automatic sensors that adjust the settings based on air quality, which can help save energy and prolong the life of the unit.
