However, this device automatically shuts down as soon as it detects that there are no more pollutants within the air.

The Bad

If you want to buy an air purifier but not sure which features to look for when purchasing one, we are here to help you. This buyer’s guide will help you understand what type of air purifier technology is best for your home.

Types of Air Purifiers

Basically, five types of air purifiers are available on the market. It’s up to you to choose one that meets all your air purifying needs and works perfectly well with the environment you live in. Discussed below are the few kinds of air purifiers that you may consider.

Ozone Generators and Ionizers

Although these air cleaners produce specific molecules, they work similarly to any other air purifier. They introduce charged particles into the air, such as ions or ozone. The unwanted floating particles in the air have a neutral charge; hence, when coming into contact with the ozone or ion particles, they also receive the charge. As a result, these particles stick to walls or other surfaces within the room.

HEPA Filters

These are the most common air purifiers, made of fiberglass, foam, cotton, or any other material that helps to trap the particles floating in the air. You need to change the air filters of these devices once or twice a month, depending on the air quality of your home.

Electrostatic Filters: Just like ozone and ion generators, electrostatic filters also charge the particles. Once charged, these particles are then filtered through the air purifiers. These air purifiers tend to perform seamlessly while killing mold spores and microbes.

Air Purifiers with Activated Carbon Filters

These purifiers are fitted with activated carbon filters. This filter efficiently traps gasses and odors. If you want to remove the unpleasant smells from your home, you can rely on the purifiers having activated carbon filters.

UV Lights

Ultraviolet rays have germicidal properties. Hence, an air purifier that comes with UV light is capable of eradicating microbes and even harmful viruses.


When it comes to the coverage of an air purifier, you need to do a little homework; before buying such a product, make sure to measure the area of your room. To get the square footage, first measure the length and width of the room and then multiply both the figures. In this way, you can get the size of your room.

Now keep this figure in mind when shopping for a suitable air purifier. Usually, manufacturers mention a recommended square foot coverage area on the product. Therefore, purchase only such an air purifier, which is capable of performing well with reference to your room size.

Average Filter Lifetime

The average lifespan of an air filter depends on its type and the environment in which it is working. Therefore, when buying an air cleaner or purifier, consider the quality and type of filter that comes with a particular model. For instance, carbon filters can only last up to six months.

If you need to clean the air and remove microbes, you will need an air purifier that comes with True HEPA filters. These filters can last up to 18 months during normal conditions. However, permanent filters can last much longer and work well unless damaged. You need to clean them once they are full of dander.

Fan Speed and Noise Level

Some other aspects that you need to consider when purchasing an air purifier include the noise level and fan speed. Make sure that the product you are buying has a minimum noise level as you won’t be comfortable when the loud noise of your air purifier continues to bother you all the time.

Besides, the fan speed should be appropriate enough to suck a large amount of air and purify it within less time. If the fan speed is too low, it will take more time to clean the air of an average room. So keep this fact in mind, when choosing the air purifier for your needs.

Easy to Clean

Air purifiers need regular maintenance that involves cleaning the filter and other parts of the device. Therefore, choose an air purifier that is easy to clean and requires less time for its maintenance. Usually, top-quality purifiers have specific design features which make cleaning and airbornepure8-20nt of the air filter much easier.


An air purifier buyer’s guide won’t serve the purpose if it fails to answer some of the frequently asked questions about such a product. Here, are some of the most common questions asked by the air purifier buyers along with their relevant answers.

How do air purifiers work?

Technically, an air purifier consists of two parts, including a fan and the filters. The internal fan sucks the air within your room and forces it through a set of filters. The particles like dust, bacteria, and pollen get stuck into the filters, leaving the air clean and purified. Some air purifiers also come with UV light and ionizers to kill the microbes.

What are the benefits of air purifiers?

If you wonder for what reason you should buy an air purifier, behold, there are plenty of them. Some of these include:

  • Removal of unpleasant odor and dust from the air
  • Helps to reduce the chances of airborne allergies
  • Reducing the risk of triggering an asthma attack
  • Eliminates the growth of mold spores and avoids chronic illnesses
  • Removes pet hair and dander
  • Cleans the air by filtering the smoke

How often to change the air purifier filter?

To maintain the performance of your air purifier, it is essential to replace its filter. The lifespan of a filter depends on the quality of air. You will also need to consider the type of filter installed in your air purifier when scheduling its airbornepure8-20nt.

The following are the different air purifier filters with their overall lifespan.

  • Permanent filters can last longer as they only need to be cleaned when full. These filters need a airbornepure8-20nt once they are damaged or worn out
  • Carbon filters can perform well for up to six months; hence, they need to be replaced after such a period
  • HEPA filters can serve their purpose for 18 months

How long should I keep my air purifier on?

The most obvious answer to this question is to keep your air purifier “on” almost 24 hours a day or when you are at home because air purifiers take some time to clean the air and make it healthy. If you switch off the air purifier occasionally, you will continue to inhale the dust and harmful microbes even after a few hours of switching on the air purifier.

How much electricity does an air purifier use?

Most of the latest air purifiers are energy-efficient. For instance, a True HEPA air purifier may consume up to 200 watts of electricity. Hence, an air purifier won’t cost you a lot when running throughout the day. However, when buying such a product, make sure that it has a good Energy Star rating.


Indoor air may even be more polluted than the outside environment, which means that you will need an air purifier that helps to remove most of the pollutants, dust, and microbes from the air. The decision regarding the purchase of an air purifier depends on the level of air quality you want for your home.

If you need to make your home free from airborne microbes and allergy-causing molecules such as dust mites, pollen, and mold spores, a True HEPA air purifier will be a viable choice. However, if you just want to clean the air, it is possible to take advantage of a less-expensive air purifier for this purpose.
