Can Air Purifiers Help With Smells?

Can air purifiers help with smells? The market is filled with different types of air purifiers, according to people’s concerns about indoor and outdoor air pollution. Air purifiers are pretty effective and can help reduce airborne viruses, which is why people are willing to buy them, and they’re becoming more popular.

The air filter companies say that their machines can get rid of bad smells and improve air quality. But is this true? Let’s look at the study on air purifiers and see if there is enough proof that they can.

Can Air Purifiers Help With Smells? 

The Environmental Protection Agency (EPA) of the United States says that getting rid of indoor air pollutants can improve air quality, but it does not eliminate all smells. The EPA’s 2018 Consumer Guide to Air Purifiers says that if good ventilation and indoor air filters work together, then the air inside your home can smell better and fresher. So, it is a good sign for a smell-free home.

There is no solid study on air purifiers getting rid of smells. However, some research is about air quality and health effects. For example, in 2021, the Science of The Total Environment Journal published a systematic review of more than 20 studies looking at how well air purifiers worked in schools, homes, and businesses. The review found that air purifiers can improve indoor air quality by 22% to 92%.

Can air purifiers help with smells? A study published in 2020 in the International Journal of Environmental Research and Public Health found that air purifiers could make average homes a little better, but not that better, and that they are literally pollution- and disease-free.

Air filters work by removing particles that can cause smells. The EPA says that no air cleaner or filter can eliminate all the particles that can cause smells. Air purifiers work best and show efficiency in single rooms, so if you want to eliminate bad smells throughout your home, you will need to purchase more than one air purifier. For best performance, the air filter should be bigger than the space it’s supposed to clean. Air purifiers with a high CADR (Clean Air Delivery Rate) can eliminate particles and cover more space.

What Types of Odors Are Eliminated By Air Purifiers?

It might depend on the air cleaner you choose. The EPA says that some air filters can eliminate moldy smells, cooking smells, pet smells, tobacco smoke, and other smells that stick around. Can air purifiers help with smells? Some air purifiers have both a particle filter and an activated carbon filter. This means that they can get rid of gas and chemical smells from things like pesticides, fire retardants, and building materials.

How Air Purifiers Remove Odors?

The fans in air purifiers pull allergens from the air into the air purifiers. The kinds of particles they catch then depend on the type of air purifier you are using. Some air filters use ionization technology that sends negative ions that catch particles. However, the EPA said these air filters can release ozone, which is bad for your health. The California Air Resource Board also says people shouldn’t use air purifiers or other machines that release ozone in their homes as they are bad for health.

But dont worry. Most air purifiers use filtering methods to remove harmful gases and particles from the air. Washable filters in air purifiers can capture pet hair, dander, and other larger particles that can cause respiratory problems. Washing and removing filters can harm humans, so follow the manufacturer’s directions.

High Efficiency Particulate Air (HEPA)

A high-efficiency particulate air (HEPA) filter is the most friendly air purifier technology. It is made up of layers of fiberglass threads and catches the smaller particles that get through the prefilter to make the air even cleaner. The particles are stuck in this high-density net when they are pulled in by the fan.

Remember that not every HEPA filter is a definition of good performance for your home. This means that the quality of products matters. Plus, these filters need to be changed according to manufacturer instructions.

Gas Phase Air Filter

Some air purifiers have an extra gas phase air filter. These filters use sorbent, which soaks up dangerous gases as they pass through them. But do remember that these filters can only get rid of a specific number of gas pollutants.

The EPA says that home air filters should not take in carbon monoxide because it is a dangerous gaseous pollutant. If you have a gas fire, a wood stove, or a kerosene lamp in your house, the air filter can’t get any of the carbon monoxide from the air.

Ultraviolet Light Filters 

Some air filters use ultraviolet light to kill germs, viruses, and allergens like mold spores and pollen. The EPA says that many germs and mold spores need more UV light than this air filters release. This means they as well as their companies say they do.

Where do unpleasant Odors come from?

  • Pet Odor: Pets like cats and dogs can make your home smell bad. Their skin flakes and oils make a smell.
