What Does an Air Purifier Do?

Air purifiers help cleanse indoor spaces by eliminating dust, allergens, and dander. Most air purifiers use fans to pull particles into the filter. Then the machine will push purified air back into the room. However, there are other types of air purifiers that remove allergens in different ways.

What is considered a safe air quality?

The air quality index (AQI) is a standard for measuring air quality and safety. To find out more about air quality, we consulted AirNow. According to its website, AirNow is a partnership between a few different government agencies, namely the US Environmental Protection Agency, the National Parks Service and the Center for Disease Control (CDC) to name a few.

AirNow developed a six-tiered, color-coded index as a way to easily understand what is considered a safe air quality. Each color has been assigned a numerical value as well. Generally speaking, a score of 100 or less, or a green or yellow level, is considered “safe.” But I’ll break down the full system below:

  • Green (0-50): The air quality is safe and poses no risk
  • Yellow (51-100): The quality is considered “moderately” safe, and shouldn’t pose much of a risk, except to those with sensitivities to air quality
  • Orange (101-150): The air is considered unsafe to specific groups. People with sensitivities may be affected, while the general population should be safe.
  • Red (151-200): The air is considered unhealthy and members of the general population may start to see negative health outcomes, like difficulty breathing, while those with sensitivities will likely experience more severe issues
  • Purple (201-300): Air has been deemed very unhealthy and many people of the general population will experience health risks if exposed for too long
  • Maroon (300+): The air is considered hazardous and governments will call for a state of emergency. Everyone is like to be affected to some degree

Air purifiers can help keep a safe air quality within your home by eliminating pollutants. Some purifiers on this list, such as the Dyson air purifier, can even gauge the air quality within your home.

Types of Air Purifiers

Which type of air purifier is right for you? Let’s take a look at the different options on the market.

  • HEPA Purifiers, like the Dyson and Honeywell, use special filters that can eliminate 99.97% of dust, mold, and other allergens. 
  • UV Air Purifiers help remove bacteria, pathogens, and viruses with ultraviolet light. 
  • Ionic Air Purifiers help remove smoke, viruses, mold, and other pollutants by emitting negative ions into the air. The ions make pollutants heavier and cause them to fall on surfaces around the room. It’s important to note, however, that ionic air purifiers can’t remove odors.

How Do Air Purifiers Compare to Other Products?

When you’re dealing with annoying allergens, it can be difficult to know which product will best ease the symptoms. To make things a bit easier, we’ll compare air purifiers with other popular products: humidifiers, dehumidifiers, and ionizers.

Air Purifier vs Humidifier

Both products can be helpful for people with allergies, but they serve very different functions. Air purifiers remove pollutants, while humidifiers add moisture into the air.

If you’re congested, a humidifier can hydrate your airways and help you breathe better. Many people place humidifiers next to their beds at night when they have a cold. Air purifiers also help people breathe better, but they do this by removing the pollutants that cause mucus buildup and sinus pressure.

Take a look at our list of the best humidifiers for some great options!

Air Purifier vs Dehumidifier

Dehumidifiers remove excess moisture from the air, which helps eliminate mildew odors and household dust. Air purifiers also help eliminate odors and dust, but they do this by removing the particles from the air.

Dehumidifiers may work better for people who live in humid environments or those who have recently dealt with leaks and floods. We recommend air purifiers for people who are sensitive to pet dander, smoke, dust, and other allergens.

Air Purifier vs Ionizer

Technically, an ionizer is a type of air purifier. It cleanses the air by emitting ions, which causes pollutants to become heavy and fall to surfaces around the room. Traditional air purifiers use fans to pull pollutants into filters, and then they push clean air back into the room.

Many people prefer ionizers because they don’t require air filters. However, ionizers don’t remove odors. And because they pull pollutants toward the surfaces in your house, you will need to clean quite often.

Air Purifier Pros and Cons

Like all products, air purifiers have pros and cons. Let’s take a look:



They can remove over 99% of pollutants, which is particularly helpful for people who have allergies.

They only cover small areas, so you may need to place several air purifiers around your house.

They help eliminate odors from the home.

Air purifiers require frequent maintenance and cleaning.

They are available in a range of prices, from budget-friendly to high-end.

They can be loud, and some people may not like the way they look in their home.

What to Look for in an Air Purifier

When shopping for an air purifier, there are a few key elements to consider:

  • Size – Many small air purifiers, like the Levoit, only cover about 200 square feet. If you need a machine that will work for a large bedroom, you may need to get a bigger air purifier such as the Honeywell.
  • Filters – If you frequently deal with allergies, you may want to get a HEPA air purifier. These machines get rid of the most pollutants from the air.
  • Fan Settings – Some products, like the Winix, have powerful fan settings that can quickly remove dust and dander from the air. If your allergies are particularly troublesome, you may want to opt for an air purifier that can rapidly eliminate the irritant.

How to Use an Air Purifier

All of the air purifiers featured on our list arrive ready to use with filters in place. Simply plug the machine into a wall outlet and choose your desired fan setting. Many products, like the Dyson and Winix, have auto settings that adjust the fan speed depending on the amount of irritants in the air.

Though it may be tempting to tuck your air purifier into a back corner, it’s important that the machine is placed a few inches away from the wall so the fan can efficiently pull pollutants into the filter. You also don’t want to place an air purifier next to a large piece of furniture, because that can disrupt airflow.

How Long to Run an Air Purifier

It’s best to run your air purifier at least 12 hours a day. This allows plenty of time for the machine to gather all of the pollutants that float throughout your home.

Air Purifier Safety Tips

Most air purifiers are completely safe to use on a regular basis. However, some air purifiers contain ozone, which can damage lungs. Ozone-producing air purifiers are banned in many places, so they are not very common.

How to Clean an Air Purifier

Many HEPA filters need to be replaced every 12 months. However, if you have a washable filter, you can soak the filter in warm water for a few hours and then rinse with cold water. If pet hair gets stuck inside the filter, you can gently remove it with a soft brush.

If your machine has a pre-filter, like the Levoit, you may need to clean it every two to four weeks with warm water and a soft brush.

How Many Air Purifiers Do I Need?

Each air purifier’s coverage is slightly different. Some, like the Honeywell, work for rooms up to 500 square feet. Others, like BlueAir, are better suited for small bedrooms and offices.

We recommend placing an air purifier in your bedroom because it can promote a more restful night’s sleep. If you want to remove pesky odors, it can also be beneficial to place a small air purifier near your kitchen or living room. The answer ultimately depends on your individual needs and preferences.
