Breathing Clean Air: The Importance and Benefits of HEPA Filters at Home

Publication date:

Submission date:


The massive wildfires raging across numerous locations worldwide are producing a significant amount of smoke, particles, and other air pollutants. As a result, the summer of 2023 has highlighted the critical importance of air quality on health. But the covid pandemic with its highly transmissible airborne virus already taught us that bad air quality leads to bad consequences. The conclusion is clear: Just like clean water, clean air is essential for a healthy life. Yet, in an age where pollution levels are on the rise, it has become increasingly challenging to find clean air, even within the confines of our homes. As we spend more time indoors, it is crucial to prioritize indoor air quality to safeguard our health. One effective solution that can make a significant difference is the use of High Efficiency Particulate Air (HEPA) filters. HEPA filters were designed more than 70 years ago to protect workers from breathing harmful airborne particles. HEPA filters were also used in hospitals for decades to help stop the spread of airborne germs and hazardous particulates. We now see them in so many other places. So, let’s explore the importance and benefits of incorporating HEPA filters into our homes.

Filtering Out Harmful Particles:

HEPA filters are designed to capture and trap microscopic particles that can adversely affect our health, such as dust, pollen, pet dander, mold spores, and even bacteria and viruses carried by aerosols. These filters work by utilizing a dense network of fibers, trapping particles of 0.3 microns size with an impressive efficiency rate of 99.97%. Smaller particles in the air run into and stick to the fibers and are removed as well. By removing these pollutants from the air, HEPA filters significantly reduce the risk of respiratory problems and allergies.

Mitigating Health Risks:

Airborne pollutants can pose severe health risks, particularly for vulnerable groups such as children, the elderly, and those with respiratory issues. By investing in HEPA filters, we can create a safer environment, minimizing the exposure to harmful particles that may trigger or exacerbate respiratory conditions like asthma. Additionally, HEPA filters can play a crucial role in reducing the transmission of airborne viruses, including influenza and the common cold.

Alleviating Allergies and Asthma:

Allergies and asthma have become increasingly prevalent in recent years. HEPA filters offer tangible relief for individuals suffering from these conditions. By effectively capturing allergens like pollen, dust mites, and pet dander, HEPA filters help create an allergen-free space at home. This allows allergy sufferers to breathe easier and reduces the frequency and severity of asthma attacks, leading to a better quality of life.

Enhancing Indoor Air Quality (IAQ):

Indoor air pollution can be as harmful as outdoor pollution, and in some cases, even more so. Fine particles, dust, or aerosols released by common household products, and furniture, can degrade indoor air quality. HEPA filters can remove them, helping to maintain a healthier indoor environment. With cleaner air, we can promote better sleep, improve cognitive function, and reduce the risk of long-term health issues associated with poor air quality. Enhancing IAQ in a house can be done using two types of systems: 1) portable HEPA air cleaners designed to run continuously, and many contain additional filters to neutralize household smells, such as cooking odors and smoke; 2) Whole-house HEPA purifier units in the home’s Heating, Ventilating and Air Conditioning (HVAC) system. The latter are generally more effective at removing airborne particles throughout the home than portable air purifiers, which treat the air in a single room, but they require a larger investment.

Addressing Urban Living Challenges:

In densely populated urban areas, the outdoor air quality is often compromised due to pollution from traffic, industry, and construction. With more home offices for self-employed or remote work, small businesses, or professional spaces at home, and the increasing amount of time at home, improving indoor air quality is getting even more important. HEPA filters act as a protective shield, providing a safe haven within our homes. They effectively trap harmful particles in our living spaces, reducing the health risks associated with exposure to urban pollutants. By investing in HEPA filters, we take control of our indoor environment and create a sanctuary of clean air amidst the challenges of city living.

Affordability and Accessibility:

One of the most remarkable aspects of HEPA filters is their affordability and accessibility. Basic HEPA filters are widely available in the market at relatively low prices. They come in various sizes and can be easily installed in air purifiers, HVAC systems, or standalone units. With a minimal investment, we can significantly improve the air quality in our homes and enhance our overall well-being.

In a world where clean air is increasingly scarce, it is essential to prioritize the air we breathe within our homes. HEPA filters offer a practical and effective solution for improving indoor air quality, mitigating health risks, and enhancing overall well-being. By investing in HEPA filters, which are both affordable and accessible, we actively contribute to creating a healthier environment for ourselves and our loved ones. The affordability and accessibility of basic HEPA filters make it easier for everyone to embrace the benefits of clean air.

But before ordering your first unit, please consider a few hints to help in choosing and using the HEPA system properly:

1) Look for certified HEPA filters (or “True HEPA” labels in some areas): Don’t consider those labeled as “HEPA-type,” “HEPA-like,” or “HEPA-style.” While they may be good filters, they haven’t been tested and certified as meeting HEPA standards.

2) Think of a pre-filter: HEPA filters, being extremely dense, are quickly clogged if the air purifier has no pre-filters to trap larger airborne particles, such as pet fur and dander. So, especially if you have pets, pre-filters lengthen the useful life of HEPA filters and are much cheaper to replace.

3) Keep it running: Air purifiers are designed to run throughout the day and night, and many will increase or decrease power as necessary, so there’s no need to turn them off and on.

4) When you use it for particle filtration (like in wildfires seasons), consider a timer or opt for a sensor: A programmable timer or sensor to monitor the air quality allows you to set a daily operating schedule that automatically turns the air purifier to a quieter sleep mode at bedtime and then turns it back up to full power during the day.

5) Avoid any ionizer or ozone generator: Some HEPA air purifiers also feature ozone generators that claim to produce healthier air by activating negative ions to destroy harmful bacteria in the air, but EPA and other authorities have determined that artificially boosted ozone levels may trigger respiratory symptoms.

6) Evaluate the Clean Air Delivery Rate (CADR): CADR ratings are measures of the volume of clean air that an air purifier can deliver per minute. The higher this rate is, the more pollutants the air purifier will remove from the air in a set period. 

7) Don’t forget room size: When it comes to air purifiers, you don’t need to choose a larger capacity rather than trusting a smaller capacity unit. Air purifiers are labeled by the size of the room (square footage) they are designed to treat. Check how many air changes are specified because one air change per hour is not enough. Target over 6 (air pollution) or even 12 (protection from pathogens) air changes per hour. 

8) Move it away from walls: A natural tendency is to position an air filter near a wall, so it doesn’t interfere with the walk space in the room. However, this can result in the purifier not drawing in enough air to function effectively. Ensure that the machine is placed at least 50 cm from walls, furniture, or any other item that could obstruct airflow.

9) Consider filter cost: HEPA filters can vary in price, so check how much replacement filters cost before buying the unit and check the manufacturer’s suggested replacement period. Also, consider if the filter can be cleaned or not. 

Furthermore, the use of HEPA filters is not limited to specific regions or demographics.The need for clean air is universal, just like clean water. HEPA filters offer a practical solution that can be implemented in any household, regardless of its size or location. With their affordability and ease of installation, they empower individuals and families to take control of their indoor environment and prioritize their health.

In addition to the direct benefits of improved health, investing in HEPA filters also yields long-term advantages. By reducing our exposure to indoor air pollutants, we can potentially prevent chronic health conditions and medical expenses or lost income associated with poor air quality. Moreover, creating a clean and healthy living space contributes to overall well-being, promoting productivity, better sleep, and a higher quality of life for everyone in the household.

However, it’s important to note that while HEPA filters are highly effective in removing particulate matter from the air, they are not a standalone solution for all air quality issues. Regular maintenance, proper ventilation, and reducing the use of chemical-laden products are also important steps in creating a healthier indoor environment. For complex situations, it is recommended to consult with professionals or experts in the field for tailored advice on achieving optimal indoor air quality.

The significance of incorporating HEPA filters into our homes and workplaces cannot be overstated. They represent an easy fix to some of the most urgent indoor air quality issues. These filters offer an affordable and accessible means to improve indoor air quality, mitigate health risks, and create a safe haven for ourselves and our loved ones. Let’s seize the opportunity to prioritize our health by embracing the power of HEPA filters. Together, we can breathe clean air, protect our friends and relatives, and build a healthier future for generations to come.
