What Is a HEPA Filter: 5 Factors to Help You Buy One

Contrary to what most people believe, your indoor air may be far more polluted than you breathe outside. With most people spending their day indoors, exposure to poor indoor air quality may cause some adverse effects on a person’s health.

Using an air purifier with a HEPA filter air purifier effectively creates cleaner and healthier air in any space. But what are the factors that you need to consider when buying one?

What Should I Look For in a HEPA Filter?

1. Right Filtration System

All air-cleaning devices need air filters to work. So, the better filter you have, the purer the air will become. A few filters highly suit pet owners because of their effectiveness in trapping pet dander. Meanwhile, others are more efficient in eliminating kitchen smoke and other unwanted odours.

Also, there are other features that you might want to consider, such as ozone generators that are highly suited for removing mould, whilst others come with more pre-filters for better absorption of large contaminants.

2. ACH Rating

ACH, otherwise known as air changes per hour, is a measurement used for quantifying an air purifier’s efficiency. It primarily refers to the number of times the device can circulate the air after cleaning it.

The size of the space that you have dictates the machine’s ACH. That is, the bigger the room is, the lower the air changes per hour.

3. Maintenance Cost

Depending on how often you need to use the air purifier or replace its filtration system will also influence how much maintenance effort you need to maintain your device. A few air purifier models have a filter replacement indicator that automatically informs you if your filter needs replacement. It’s an excellent feature, especially for those who forget the replacement date.

4. Noise Level

Another factor that you need to consider is the noise level. Remember that the higher the noise level is, the more uncomfortable it is to use the air purifier throughout the day. So, ensure that you only buy a machine that won’t exceed 40–50 decibels.

5. Features

Modern air purifiers have smart features that make your life easier and comfortable. Examples are air quality monitoring and a programmable timer.

Why Is HEPA Filter Important?

High-efficiency particulate air (HEPA) filters are the primary reason why many establishments install air purifiers in homes, offices, schools and even hospitals. That’s because a HEPA filter can eliminate 99.97% of pathogens in the air, including chemical compounds, dust and even bacteria.

Here are a few more reasons why the HEPA air filter is essential:

‣ Effective at Treating Allergies

For people prone to allergies, experiencing various respiratory complications caused by poor indoor air quality is something they face every day. What’s worse is that other conditions, such as asthma, can worsen with untreated indoor air. 

Using a HEPA air purifier in Australia is an effective way to treat allergies. An air purifier can effectively capture the allergens, which can cause various adverse effects, including a stuffy or runny nose. This effectively eases your symptoms and improves your health.

‣ No Byproducts

What’s great about using a HEPA air filter is that it doesn’t emit any harmful chemicals or byproducts into the air. Unlike other air filters, a HEPA filter has a unique design that works effectively without producing any byproducts. Even more, it’s ecologically friendly, ensuring that you’re not harming the environment when using it.

‣ Easily Accessible

You can also purchase the best HEPA air purifier in Australia at any appliance store. A few devices with this type of feature include vacuum cleaners, humidifiers and many more. However, you need to ensure that you’re buying from a reliable store to guarantee its quality.

‣ Reduces the Impact of Smoking

Does someone smoke in your household? If you do, then having an air filter is a practical choice.

A HEPA filter air purifier effectively eliminates the smoke particles and other harmful contaminants from your indoor air. The risk of developing adverse effects from smoking is high, especially for babies and older people. That’s why it’s essential to get one installed to help get your family protected.

Are There Different Grades of HEPA Filters?

Although there is only a single type of HEPA air filter, this type of filter has grades that range from H10 to H12. So, technically, the higher the grade, the better the filtration.

HEPA filter bunnings H13 up to H14 hold the highest tier of filtration and are often referred to as medical-grade quality. At the same time, H10 up to H12 filters can only effectively trap at least 85 to 99.5% of particles at least 0.1 microns in diameter.

Air purifiers within the H13–H14 bracket are often placed in electronic control rooms and pharmaceutical manufacturing because of their excellent particulate retention rate.

What Is HEPA Filter Housing?

HEPA filter air purifier housing refers to the technique of installing the air purifier directly into the ductwork system to ensure that every room gets a high-quality air supply, especially in areas where it’s required.

Additionally, the HEPA filter housing only allows the air to pass through for a minimal period to collect all the harmful contaminants from the entire house.
