When you’re vacuuming your house, there’s a silent hero that often goes unnoticed: the HEPA filter in vacuum cleaners. While many of us focus on the power and design of the vacuum itself, it’s the HEPA filter that truly sets apart the champions of cleanliness.

But are HEPA filters really just another accessory, a clever marketing trick to make us buy one model over another? 

No. HEPA filters are a necessity for healthier homes and cleaner air. This is especially true in New Zealand where we are a nation of pet owners. We also have an issue with house dust mites in New Zealand, because they thrive mainly in temperate climates where there is high humidity (over 75%) and Auckland’s average for example, is above 80%.

Both Allergy New Zealand and the Asthma Foundation recommend using vacuum cleaners with HEPA filters to get rid of animal fur and dander as well as house dust mites.

 So what is a HEPA Filter?

HEPA is an acronym for High Efficiency Particulate Air. These filters are designed to trap a high percentage of particles that pass through them, including microscopic ones that can’t be seen by the naked eye. Originally developed during World War II to prevent the spread of radioactive contaminants, HEPA filters have since found their way into various applications, including vacuum cleaners.

 Why should you choose HEPA?

 Traps Allergens and Irritants: HEPA filters are incredibly efficient at capturing allergens such as pollen, pet dander, and dust mites, as well as irritants like mould spores and bacteria. For individuals with allergies or respiratory conditions like asthma, this can make a significant difference in their quality of life by reducing triggers in the air.

 Improves Indoor Air Quality: Traditional vacuum cleaners often recirculate small particles back into the air through their exhaust systems. HEPA filters prevent this by trapping particles as small as 0.3 microns with an efficiency of 99.97%. This means cleaner air for you and your family to breathe.

 Enhances Cleaning Performance: While the primary purpose of a vacuum cleaner is to remove visible dirt and debris, the inclusion of a HEPA filter ensures that even the smallest particles are captured, leaving your floors and surfaces truly clean. This is especially beneficial for homes with pets or high levels of foot traffic.

 Reduces Odours: HEPA filters can also help eliminate unpleasant odours by trapping odour-causing particles, leaving your home smelling fresher and cleaner.

Protects Vacuum Components: By capturing particles before they reach the vacuum’s motor and other internal components, HEPA filters can extend the lifespan of your vacuum cleaner and reduce the need for maintenance or repairs.

Making the Right Choice

Brand and brand reputation are very important when choosing a vacuum cleaner with a HEPA filter. After all, if it’s important to the health of you and your family, you need to choose a reputable brand who are leaders in this field. Miele who have been making quality appliances for over 125 years have a range of cannister and stick vacuums with advanced HEPA filters. Miele vacuums also feature a sealed system, which filter the air before it’s released back into the environment. This prevents any particles from escaping and being reintroduced into the air. This ‘sealed’ system is also one recommended for use by people with allergies and asthma.

So when shopping for a vacuum cleaner with a HEPA filter, it’s essential to ensure that the filter meets HEPA standards and is properly sealed within the vacuum to prevent leaks. Additionally, consider factors such as suction power, manoeuvrability, and accessories to find the best option for your needs.

Final Thoughts

While HEPA filters may not be the most glamorous feature of a vacuum cleaner, their impact on indoor air quality and overall cleanliness cannot be overstated. Investing in a vacuum with a HEPA filter is an investment in your health and well-being, providing peace of mind knowing that your home is not only visually clean but also free of harmful particles that can affect your respiratory health. So, the next time you’re in the market for a new vacuum cleaner, remember to prioritize the unsung hero – the HEPA filter. Your lungs will thank you for it.
