What is an Air Purifier? Learn Its Functions and Benefits

Given rising air pollution, maintaining indoor air quality is essential. Using an air purifier is an effective solution to protect your home.

An air purifier is an electronic device that filters out harmful particles and pollutants and releases them back into the fresh air.

Are you familiar with this device? This article will thoroughly inform you about air purifiers, from their definition, working methods, functions, benefits, and the comparison between humidifier and dehumidifier.

What is an Air Purifier?

An air purifier is an electronic device designed to filter and purify air that has been contaminated with harmful particles and pollutants.

The device works by drawing in the air in the room, then filtering it with multiple filters and expelling it back into the room in the form of clean air, resulting in better air quality.

The main focus of the appliance’s work is on providing a gradually better quality of clean air to be breathed indoors.

How Does it Work?

Simply put, an air purifier works by drawing air in, then filtering it with multiple filters, and expelling clean air back out. Here’s how it works in detail:

• Draws in air: The fan on the device pulls dirty air into the filtration system.
• Filtering process: The air will pass through several types of filters that will capture different types of contaminants.
• Discharges clean air: The filtered air is expelled back into the room in the form of clean air.

The Types 

Air purifiers are equipped with several filters with different functions depending on the type of contaminant. Here are some of the types of filters commonly found in the appliance:

• Pre-filter: Captures large particles such as dust and hair as the first layer of filtration.
• High-Efficiency Particulate Air (HEPA) filter: Removes small particles such as dust, pollen, pet dander, and even some types of bacteria and viruses.
• Activated carbon filter: Removes unpleasant odors, gases, and harmful chemicals such as cooking odors, pet odors, or cigarette smoke.
• UV-C filter: Kills bacteria, viruses, and mold with ultraviolet light.
• Electrostatic filter: Attracts and traps harmful particles from the air using an electric field.
• Ionizer filter: Works to remove positively charged particles by releasing negative ions into the air.

The Benefits 

Using an air purifier regularly will provide many benefits, especially for those of you who have certain health problems. Here are some of the main benefits:

1. Ward off outdoor pollution

One of the benefits of an air purifier is its ability to ward off outdoor pollution. This device can be an added protection against exposure to dirty air for those of you who live in pollution-prone big cities or near industrial areas.

2. Reduces indoor smoke

3. Eliminates unpleasant odors

The activated carbon filter in the air purifier is able to help eliminate unpleasant odors. So that odors such as cigarette smoke, cooking odors, pet odors, or odors from the surrounding environment to be filtered properly.

4. Reduces the risk of allergies and asthma

Reducing the risk of allergies and asthma is another benefit of an air purifier. It reduces the risk of allergy flare-ups and helps provide fresh air for asthma sufferers with its ability to filter allergens from the air.

5. Improves sleep quality

Air Purifier vs Humidifier vs Dehumidifier: What are the Differences?

True air purifiers, humidifiers, and dehumidifiers have different functions. You will know the difference by knowing the definition of humidifiers and dehumidifiers first.

What is a Humidifier?

A humidifier is a device that works to add moisture to the air in a room by spraying water vapor into the air. This tool is often referred to as a humidifier and is useful for overcoming dry air that can irritate the skin, lips, and throat, and even worsen the symptoms of respiratory diseases.

What is a Dehumidifier?

Humidifiers may be more familiar than dehumidifiers. They work in opposite ways, with a humidifier adding moisture to a room that is too dry, while a dehumidifier reduces moisture in a room that is too humid.

Mold, unpleasant odors, and health problems can arise from air that is too humid. This is where a dehumidifier comes in, which collects moisture and releases it in the form of water.

The Difference

1. Main function 

• Air purifier: Designed to filter the air from harmful particles such as fine dust, cigarette smoke, pet dander, mold spores, and allergens.
• Humidifier: Designed to increase the humidity of indoor air so that it feels moist and comfortable, especially during the dry season.
• Dehumidifier: Designed to decrease the humidity of indoor air so that it feels dry and comfortable, especially during the wet season.

2. How they work

• Air purifier: Works by sucking in the surrounding air, filtering it with several layers of filters, then blowing back clean air.
• Humidifier: Works by evaporating water from the tank into the air to moisturize the air in the room.
• Dehumidifier: It works by extracting water vapor from overly humid air and collecting it in a container that periodically needs to be removed when full.

3. Purpose of use

• Air purifier: Aims to treat indoor air pollution.
• Humidifier: Aims to moisturize air that is too dry.
• Dehumidifier: Aims to reduce excess air humidity.

4. Location of placement

• Air purifier: Can be placed anywhere as long as the room is not open.
• Humidifier: Suitable for dry and less humid rooms.
• Dehumidifier: Suitable for humid and less dry rooms.

5. Water requirements

• Air purifier: Does not require water as it filters dirty air.
• Humidifier: Requires large amounts of water, up to 3 liters.
• Dehumidifier: Does not require water, extracting water vapor from the air.

6. Benefits

• Air purifier: Helps prevent and reduce allergies, asthma, and respiratory problems for long-term indoor wellness.
• Humidifier: Helps moisturize dry skin, chapped lips, sore throat, and flu symptoms due to dry air.
• Dehumidifier: Helps prevent mold growth, reduces musty odors, and helps with respiratory problems caused by too much humidity.

Matching Appliances to Your Environment

Choosing between an air purifier, humidifier, or dehumidifier can’t be based solely on general preference. You need to know whether the problem in your room is related to smoke or improving air quality.

If your issue is urban smog, airborne allergens, or smoke from household activities, an air purifier will protect your respiratory health. If the air in your living space is too dry, a humidifier will prevent skin irritation and discomfort in your mucous membranes. If your living space suffers from excessive dampness, heavy condensation, or persistent mold risk, a dehumidifier is the ideal solution.

Once you know whether your home is dealing with particulate pollution or excessive humidity, you can choose the right device. This will help you invest in technology to create a healthy and comfortable living environment.
