How Do Air Purifiers Work?

Have you ever wondered what hidden pollutants might be lurking in the fresh air of your home? EPA research indicates that indoor levels of pollutants may be two to five times — and occasionally more than 100 times — higher than outdoor levels. Given that most people spend about 90 percent of their time indoors, maintaining clean indoor air is essential for our health. So, how do air purifiers protect our family’s well-being? How do they ensure the air we breathe is fresh? Let’s explore how air purifiers help create a fresher, healthier home!

What's an Air Purifier, and What Are Its Benefits?

An air purifier is designed to improve indoor air quality by filtering out pollutants, allergens, and harmful substances, resulting in fresher, more breathable air. The benefits of air purifiers are numerous and significant:

Improved Air Quality: Air purifiers effectively remove dust, pollen, pet dander, and other allergens from the air, enhancing indoor air quality.
Reduced Allergy Symptoms: By filtering out common allergens, air purifiers can help alleviate symptoms like sneezing, runny noses, and itchy skin.
Removal of Harmful Substances: Many air purifiers can capture volatile organic compounds (VOCs), formaldehyde, and other harmful gases, protecting your family from these pollutants.
Elimination of Viruses and Bacteria: High-efficiency filtration systems can help reduce airborne viruses and bacteria, lowering the risk of infection, especially during flu season or pandemics.
Odor Elimination: Air purifiers effectively remove kitchen smoke, pet odors, and other unpleasant smells, providing fresh air throughout your home.
Enhanced Sleep Quality: Clean air improves your sleeping environment, helping you achieve better sleep quality and wake up feeling more refreshed.
Real-Time Air Monitoring: Many modern air purifiers come equipped with sensors that monitor indoor air quality in real-time, providing data feedback to help you understand and improve your home's air conditions.
Health Protection for Family Members: Air purifiers create a safer environment, particularly for homes with children, elderly individuals, or those with weakened immune systems, reducing health risks.
Improved Quality of Life: By creating a fresh and healthy indoor environment, air purifiers can significantly enhance your overall quality of life, making your home more comfortable and enjoyable for your family.

How Does an Air Purifier Operate?

How does the air purifier operate to enhance indoor air quality?

1. Air Intake: The air purifier draws in air from the surrounding environment through its air inlet.

2. Filtration: The incoming air passes through 1 or more filtration systems, such as a 5-stage filtration system:

Fabric Pre-Filter: Captures larger particles such as lint, fibers, hair, and pet fur. This protects the main filter and maximizes its lifespan.
Nylon Pre-Filter: Filters out finer debris and larger particles, such as cotton and small hairs. It pre-filters larger particles, keeping them out of the main filter for easier maintenance.
Main Filter: Deeply filters fine particles like dust, smoke, pollen, and pet dander.
HEPA Filter: Capable of capturing extremely small particles, including smoke, odor sources, and allergens, with a purification efficiency of 99.97% for particles as small as 0.3 μm. Filters out formaldehyde, benzene, ammonia, hydrogen sulfide, and volatile organic compounds (VOCs).
Activated Carbon Filter: Adsorbs gaseous pollutants from pets, kitchens, secondhand smoke, and mold, reducing unpleasant odors in the environment.

3. Air Release: The purified air is pushed back into the room through the air outlet.

4. Monitoring and Maintenance: A PM2.5 sensor monitors air quality and indicates the air quality status through the air quality indicator (Blue-Very Good; Green-Good; Orange-Moderate; Red-Poor).

What is a HEPA Filter?

A HEPA (High-Efficiency Particulate Air) filter is a highly effective air filtration system that captures very small particles from the air. According to international standards, a HEPA filter must be able to remove at least 99.97% of particles that are 0.3 microns in diameter. This makes them very effective at removing dust, pollen, pet dander, smoke, and certain bacteria and viruses.

Key Features of HEPA Filters:

High Efficiency: Capable of capturing extremely small particles, significantly improving air quality.
Dense Structure: Made up of multiple layers of fibers that trap and block airborne particles.
No Chemicals: HEPA filters do not use chemical agents; the filtration process is physical, making them safe for health.
Versatile Applications: Widely used in home air purifiers, vacuum cleaners, hospitals, and laboratories where high cleanliness standards are required.

Do You Really Need an Air Purifier for Home?

Consider the following factors to determine whether you need an air cleaner purifier:

Allergy Symptoms: If you or your family members frequently experience allergy symptoms like sneezing, a runny nose, itchy eyes, or skin irritations—especially at home—it could be a sign of allergens in the air.
Indoor Air Quality: If you notice unpleasant odors or stuffiness indoors, or if there are chemical smells after cooking or cleaning, this may indicate that the air quality is poor air.
Respiratory Issues: If you or your family members have asthma, bronchitis, or other respiratory problems, an air purifier can help filter out irritants and allergens, improving breathing conditions.
Pets: If you have pets, their dander and odors can impact air quality. An air purifier can effectively remove these allergens and smells.
Living in a Polluted Area: If you live in a heavily polluted area or near factories or busy roads, using a good air purifier can help reduce harmful substances in the air.
Seasonal Changes: During pollen season, if you're sensitive to pollen, an air purifier can help filter out pollen particles from the air. In wildfire season, it effectively filters out the fine particles found in smoke and ash caused by wildfires.
Home Sealing: If your home is well-sealed and poorly ventilated, indoor air can easily become polluted. The home purifier can help improve air circulation.
Health Precautions: Even without noticeable symptoms, many people choose to use air purifiers as a preventive measure, especially in homes with infants, elderly individuals, or those with weakened immune systems.

If any of these factors resonate with you, investing in an air cleaner for house may be a wise choice to create a healthier living environment for your family.

Indoor air quality is often overlooked, yet it plays a crucial role in our health and overall well-being. Air purifiers, equipped with advanced filtration systems and smart sensing technology, effectively trap tiny particles, allergens, and pollutants from the air, quietly ensuring that you and your loved ones stay safe and healthy.
