Before we get to the top vacuums with HEPA filters, it’s important to understand what a HEPA filter does. As we’ve mentioned, the HEPA filter’s job is to force air through a mesh of fiberglass. Dust, mould spores, pet dander and other microscopic particles are caught in this mesh and can’t escape.
Some of the benefits of a HEPA filter include:
- Helps reduce the chance of asthma flare-ups. HEPA filters remove smoke and dust from the air, which is important for people with asthma.
- Helps reduce the chance of allergic reactions. By removing pollen, dust and other allergens from the air, allergic reactions are less likely. This is why a HEPA model is sometimes called an allergy vacuum cleaner.
- Improved air quality. Even if you don’t have an allergy or asthma, a HEPA filter reduces contamination in vacuum exhaust air.
It’s worth noting that you can often buy HEPA filters for vacuums that don’t come with one as standard. This may be the cheaper option – but it’s important to choose a filter that does the job properly. You can get a good idea of the quality by looking at test results, factors such as Minimum Efficiency Reporting Value and how buyers have rated the model.
Another thing to remember is that some manufacturers are moving away from HEPA filters in favour of other filtration systems.
Hireavac, for example, is being built with a cylinder system that uses centrifugal forces to remove allergens. For this reason, you may need to buy an older model if you want to get a HEPA filter (although there are still plenty of excellent options).
The rest of this article contains, in our opinion, four of the best HEPA filter vacuum cleaners on the market at the moment (these models all come with a HEPA filter as standard). Each provides excellent value for money and has received high ratings from buyers – but if you feel we’ve missed a great model, let us know in the comments. Let’s get started!
How to Choose a HEPA Filter Vacuum?
When you’re in the market for a vacuum with a HEPA filter, the choices can feel daunting. But with some research and knowing what factors to prioritize, you can simplify the process. Here’s what to keep in mind:
- Rating: Pay attention to the filter’s rating. HEPA filters are graded based on their efficiency in capturing particles of a certain size. Look for filters with a higher rating for better performance.
- Manufacturer’s Recommendations: Follow the manufacturer’s guidelines. Different vacuums may have specific filter requirements for optimal performance. Adhering to these recommendations can ensure the longevity and effectiveness of your vacuum.
- Price: Consider your budget. HEPA filters can vary in price, so weigh the cost against the features and performance you desire. Remember that investing in a quality filter can lead to better air quality and cleaner surfaces in your home.
- Overall Effectiveness: Evaluate the filter’s overall effectiveness. Beyond its rating, consider factors like durability, ease of maintenance, and compatibility with your vacuum model. A filter that effectively traps allergens and pollutants while lasting a long time will provide the best value for your investment.
By taking these factors into account, you can confidently choose a HEPA filter that meets your needs and ensures cleaner air in your home.
Frequently Asked Questions
Are HEPA Filters Washable?
HEPA filters are generally not washable. Washing them can damage the delicate fibres that make up the filter and reduce their effectiveness at capturing particles. Instead, they should be replaced according to the manufacturer’s recommendations to maintain optimal performance. Some filters may have a pre-filter that can be washed or replaced to help extend the life of the HEPA filter itself. Always refer to the specific instructions provided with your HEPA filter for proper maintenance.
When Should I Change a HEPA Filter?
The frequency of changing a HEPA filter depends on several factors such as usage, air quality, and the manufacturer’s recommendations. However, a general guideline is to replace the HEPA filter approximately every 6 to 12 months for optimal performance.
If you notice a decrease in the air purifier’s efficiency or if it’s struggling to maintain air quality, it might be time to replace the filter sooner. Additionally, if you live in an area with high levels of air pollution, or pet dander, or if someone in your household has allergies or respiratory issues, you may need to replace the filter more frequently.
Always refer to the specific instructions provided by the manufacturer for your particular HEPA filter model, as they may have specific recommendations based on their design and intended use.
How Does a HEPA Filter Vacuum Work?
A HEPA filter vacuum works by using a high-efficiency particulate air (HEPA) filter to trap tiny particles such as dust, pollen, pet dander, and other allergens. Here’s how it typically works:
Suction: The vacuum cleaner uses a motor to create suction, which draws in air and debris from the surface being cleaned.
Pre-filtration: Before reaching the HEPA filter, the incoming air usually passes through one or more pre-filters. These pre-filters catch larger particles like hair and debris, preventing them from clogging or damaging the HEPA filter.
HEPA filtration: The air then enters the HEPA filter. HEPA filters are made of densely packed fibers arranged in a random pattern. These fibres create a maze-like structure that traps microscopic particles as small as 0.3 microns with a high degree of efficiency, typically capturing over 99.97% of particles.
Clean air emission: Once the air passes through the HEPA filter, it’s cleaned of most allergens and other contaminants, and then expelled back into the room.
Collection: Meanwhile, the debris collected by the vacuum, both large and small, is stored in a dustbin or a vacuum bag, depending on the vacuum model.
HEPA filter vacuums are particularly beneficial for people with allergies or asthma because they effectively remove allergens from the indoor environment, improving air quality and reducing the risk of respiratory issues.
