What is a HEPA Filter Air Purifier? Benefits of Owning One

A HEPA filter air purifier is a device that can be used to clean the air in your home. It does this by filtering out dust, pollen, mold spores and other airborne particles. You may be wondering if this is something you should get for your home? The answer depends on what kind of environment you live in and how sensitive you are to allergens or pollutants. We will go over the pros and cons of owning one so that you can decide whether it’s right for you!

What is HEPA Filter Air Purifier?

HEPA stands for “High Efficiency Particulate Air” and is a type of air filter that captures particles at least 0.3 microns in size. HEPA filters are used in many industries, such as hospitals and laboratories, to purify the air from germs or other harmful bacteria.

They work by trapping pollen, dust, spores and other microscopic allergens before they can escape into the air.

These filters use a dense weave of fibers that capture particles that are invisible to the naked eye before they have an opportunity to enter your home’s living space where you spend most of your time.

They also trap larger particle matter like pet dander so you won’t be breathing them in either!

Pros and Cons of HEPA Filter Air Purifiers


HEPA air filters are not expensive and they last a very long time.

If you live in a no or low VOC area, this could be the perfect tool to help you breathe easy.

You may also end up with less allergy symptoms if you are sensitive to pet dander or dust.

HEPA air purifiers can increase your home’s air quality by 10-20% by doing away with particles that would otherwise circulate through the air.

The increased concentration of negatively charged ions from the purifier can also benefit those who suffer from asthma and other respiratory conditions.


Some people find that HEPA air purifiers do not offer enough relief for allergy sufferers as they are not 100% effective.

They also do not get rid of odors or chemical based pollutants like smoke, VOCs and gases from paint or other household chemicals so you may still have some respiratory issues even with a filter that is working properly.

It’s important to note that these filters cannot trap mold spores which can be harmful to those who suffer from asthma or allergies.

You will also need a separate filter for pet hair as these filters do not remove it.


Are HEPA filters harmful?

No, they are not harmful. The latest scientific studies have shown that HEPA filters are safe to use and don’t cause any issues.

Do I need a separate filter for pet hair or odors?

No, you do not need a separate filter as this is included in most models. You may want to check whether it is washable though as not all HEPA air purifiers are.

How long do HEPA filters last?

A HEPA filter typically has a lifespan of three years. Some filters can last longer but it all depends on the manufacturer and how often you use them as some models are more durable than others..

Can mold grow on HEPA filters?

Yes, mold can grow on HEPA filters. This is why it’s important to clean them regularly and properly maintain them in order for the filter to be effective.
