Are you considering buying an air purifier for your home? Great choice! There are many reasons why you may choose to purchase a home air purifier.

How does an air purifier work?

An air purifier, also called an indoor air cleaner, functions by pulling in polluted air, treating that air inside the device with various filtration technologies, then recirculating the purified air back into your space.

Home air purifiers can vary greatly depending upon what they are designed to filter. The following are some examples of filtration technologies that may be used in an air purifier:

These devices should not be confused with dehumidifiers or ionisers commonly used in homes. As listed above, some, but not all, air purifiers for your home do come equipped with dual purification and ionisation technologies. Eoleaf’s air purification devices come equipped with 8 of the above technologies, making them capable of combatting nearly all airborne contaminants.

The advantages of having an air purifier in the home

In-home air purification devices can serve many purposes and can be beneficial to anyone. Some of the main reasons that people look to buy home air purifiers are to improve indoor air quality, eliminate indoor odours, reduce the risk of illness, and/or improve sleep quality.

Improve indoor air quality

Did you know that indoor air is 5-7 times more polluted than outdoor air? With new buildings now being designed with energy efficiency in mind, this can create an airtight effect. Stale air becomes trapped indoors and is unable to circulate properly. Pollutants from the outdoors, especially in urban environments, can enter the home and have no way of escaping. Pollutants generated from products used indoors, like paint and solvents containing volatile organic compounds (VOCs) or pesticides, can also be quite problematic. Mould and dust in the home also damage your indoor air quality

Air purifiers with high-quality home air filters can eliminate a multitude of contaminants from your indoor air including:

Remove bad odours

Another benefit of purchasing a home air purifier is their capacity to remove bad odours at home, such as cigarette smoke, air pollutants, cooking, or pets can take a significant toll on our well-being.

In addition to emitting an unpleasant smoky odour in your home, cigarette smoke (first-hand, second-hand, and third-hand) can increase our risk of almost every type of cancer, respiratory illness, heart and lung disease, stroke, pregnancy complications, decreased fertility, and diabetes. Furthermore, tobacco is ten times more polluting to our breathing air than diesel trucks1, and its residue can last on surfaces for years.

Reduce the risk of illness

An air purifier can help ward off epidemics or pandemics (like COVID-19) by reducing viral and bacterial spread. The COVID-19 pandemic inspired widespread use of air purifiers in public settings like schools, hospitals and other medical practices, hair salons, and restaurants.

These devices can also help ease symptoms of pre-existing conditions, providing relief to sufferers of asthma or COPD who are highly sensitive to air pollutants. A recent study showed that air purifiers equipped with HEPA filters can reduce PM2.5 levels by up to two thirds compared to low-quality filters, leading to a 73% increase in respiratory elasticity and, thus, improved breathing quality2.

The best home air purifiers can also improve your allergies! Most allergens, like pollen, measure about 2.5 µm in size, and air purifiers for the home that are equipped with HEPA filters can remove all airborne particles down to a size of 0.01 µm. It also helps eliminate airborne dust mites from your home.

Improve sleep quality

Removing pollutants from your breathing air can help improve your sleep quality. As a result of insufficient ventilation, stale air containing contaminants (including build-up of carbon dioxide in your home), pollutants, allergens (especially dust and dust mites in your home), chemicals, humidity, and/or pathogens may all negatively impact your ability to get a full night’s rest.

How to choose the best home air purifier?

Due to the extensive variety of products available on today’s market, multiple factors must be considered before purchasing your air purifier.

Filter types

As seen above in the paragraph on how air purifiers work, there are many different filtration technologies. Be sure to select the ones that match your needs and your sources of pollution. At Eoleaf, we recommend at least a medical-grade H13 HEPA filter and a UVC lamp.


Air purifiers generally come with two costs to consider: 1) the initial purchase of the device and 2) maintenance costs. Devices that come equipped with more features and filtration technologies (medical-grade HEPA filters versus non-HEPA filters, for example) will likely be more expensive than your basic air purifier.

Regarding maintenance costs, some air purifiers require regular filter changes (usually for cheaper filters), whereas higher-quality filters, like Eoleaf’s, need to be changed once annually.

Energy consumption also varies between devices: devices sized for larger spaces will consume more energy than those sized for smaller spaces. When choosing your device, ensure that you search for one that is energy-efficient since air purifiers are most effective when they are left running on a regular  basis. To provide an example, Eoleaf’s AEROPRO 40 consumes only 49W/h on Speed 4, its highest setting.


Depending upon where you plan to place your air purifier in your home, noise will be a consideration. If planning to put your device in your bedroom, it is important to find a device that is powerful but quiet. Some devices, like Eoleaf’s, come equipped with a Night Mode setting that turns off all indicator lights and keeps your air purifier running at a low speed so as not to disturb your sleep.

The size and location of your space

Air purifiers are built to purify the air in spaces of a maximum size. It is important to choose an air purifier that is properly sized for the room in which you plan to install it; if your device is not properly sized, the air in the room may not be properly filtered.

Once you’ve chosen your ideal air purifier, make sure to install it in a location that has the highest concentration of pollutants and has the most air flow. Some common places to install a home air purifier are in the kitchen, the living room, and the bedroom.
