Debunking the Myths About HEPA Filtration Systems
HEPA (High Efficiency Particulate Air) is a globally recognized efficiency standard for air filters, designed to tackle indoor air pollution. These filtration systems, trusted in hospitals and laboratories for controlling airborne particles, are now making homes and businesses healthier by cleansing and purifying indoor air.
In recent years, HEPA filtration systems have grown in popularity, leading to some common misconceptions. Below, we debunk the top 10 myths about HEPA filters and air purifiers.
1. HEPA Filters Only Capture Particles Larger Than 0.3 Microns
Airborne particles come in all sizes, from visible dust to microscopic pollutants. Contrary to this myth, HEPA filters capture particles both larger and smaller than 0.3 microns, including bacteria, viruses, and fine dust. For perspective, a micron is 1/25,000 of an inch, far smaller than what the naked eye can see.
2. HEPA Technology Is “Outdated”
While HEPA technology was first introduced in the 1940s, it remains a gold standard because it works. Over time, the technology has evolved with new advancements, including the integration of carbon filters for enhanced purification. The proven foundation of HEPA filters ensures reliable performance, even with modern upgrades.
3. Air Purifiers Aren’t Needed in Air-Conditioned Rooms
Air conditioning systems may have basic filters to protect the unit, but they don’t actively purify the air. Older AC systems can even contribute to indoor air pollution by harboring mold and circulating stale air. A HEPA filtration system works alongside your HVAC system to ensure cleaner, healthier indoor air.
4. Air Purifiers Solve All Respiratory Issues
HEPA air purifiers can significantly reduce airborne particles that trigger allergies and asthma symptoms, but they aren’t a cure-all. High-quality HEPA systems can filter out up to 99.95% of pollutants, including pollen, mold, and dust, offering relief for those with respiratory conditions. While they can’t eliminate every symptom, the improvement in air quality can make a noticeable difference.
5. HEPA Filters Need an Antibacterial Coating
HEPA filters are designed to trap airborne particles, including bacteria and viruses, without the need for additional coatings. Made of synthetic, cellulose, or glass fibers, the unique crisscross design effectively captures particles, whether they are alive or inert. Antibacterial coatings are unnecessary for HEPA filters to perform their job.
6. HEPA Air Filters Eliminate Odours
HEPA filters are excellent at removing airborne particles but aren’t designed to tackle odours or gases. For odour elimination, a filtration system with an activated carbon filter is essential. A high-quality HEPA system paired with carbon filtration can effectively address both airborne pollutants and unpleasant smells.
7. Air Purifiers Remove Tobacco Smoke
While HEPA systems can trap some particles from tobacco smoke, they aren’t designed to eliminate the associated odours completely. Specialized systems with carbon-based filters are more effective for removing the smell of tobacco. However, for homes free of tobacco use, a HEPA system works well to improve overall air quality.
8. All Air Purifiers Are the Same
Not all air purifiers are created equal. HEPA filtration systems vary in size, technology, and price. Deluxe systems often include features like carbon filters and greater coverage, making them more effective for whole-home solutions. It’s important to choose a system tailored to your home’s needs and air quality goals.
9. Windows Must Be Closed for Air Purifiers to Work
While keeping windows closed can help reduce the workload on a filtration system, it’s not a strict requirement. Fresh outdoor air can be beneficial in many cases unless there are specific air quality concerns, such as wildfire smoke. HEPA systems will continue to function effectively, even with windows open occasionally.
10. Air Purifiers Eliminate the Need for Dusting
This myth needs some perspective. HEPA systems trap airborne particles but can’t remove settled dust from surfaces. While air purifiers reduce the amount of dust circulating in the air, regular cleaning and dusting are still necessary to maintain a clean home environment.
