Are Air Purifiers Safe for Your Health? Myths and Facts

It’s true that Air purifiers can cause headaches, sore throats, coughing, asthma, and other problems. But not all of them are dangerous and cause damage. Some of them are good for your health and can help you with many diseases. Are air purifiers safe? How do we know which are good for health and which are not?  We will tell you everything to make sure you know whether air purifiers are safe or not.

What is an Air Purifier?

An air purifier is a machine used to clean the air in a house. It can be used at home or at a business. It has to be connected to the heating, ventilation, and air conditioning (HVAC) system. Are Air Purifiers Safe? The majority of air purifiers are used to remove particles and gases. One air purifier can’t do everything. Many air cleaners have more than one filter. Some have filters for particles, gases, chemicals, and smells. Some other filters are used to remove gases, chemicals, and odors.

How Do Air Purifiers Work?

Most air purifier filters work the same, even though they look different. After filters, there is a built-in air purifier that brings air into the room and passes it through one or more filters. The cleaner air is then circulated back into the room.

There are different weights of air purifiers, but most are light enough to move from room to room. Some can be hung on the wall, and there are also models that you can wear and use on your computer.

Types of Air Purifiers

Let’s talk about different purifiers and discuss the benefits of each. I have grouped them by technology so that you can find the problems and benefits of each and keep those in mind before purchasing an air purifier. These  are the air purifiers according to the technologies:

Ozone Generators: 

These air purifiers create large ozone levels and circulate them around your house. It helps in removing mold, germs, and pets die in huge amounts of ozone, a cleansing gas.

Electronic Air Purifiers: 

These types of air purifiers work in air by electronically charging the air.  Just like static electricity sticks clothes together, air molecules also attach to dust and other particles. With the help of the properties of  Corona Discharge, Electrostatic Precipitation, Ionization, and UV light it cleans the air.

Mechanical Filtration: 

These air purifiers drive air through filters to remove particles. HVAC filters, air purifiers, and ceiling-mounted are some of the types of air purifiers that use this technology.

Are Air Purifiers Safe for Your Health

Some other air purifiers

  • Filtered (capturing airborne pollutants in filters)
  • Electrostatic (creating charged particles to trap particles in filters),
  • UV light (targeting viruses and bacteria).

Are Air Purifiers Safe and Effective?

Yes, air purifiers are safe and effective, but only partially. It depends on these factors:

  • Kinds of household contaminants
  • Cleaning like house ventilation, area size, and filter type and quantity. The air purifier uses the CADR rate.
  • How much can you manage contamination sources
  • Regularity of air purifier use

Airborne particles can stick to furniture, bedding, carpets, and hard surfaces like walls and ceilings. Your housecleaning practices will impact your air purifier’s workload.

Which home contaminants should I worry about?

Particulate matter (PM) surrounds most pollutants. Airborne PMs are characterized as either PM2.5 particles (2.5 microns or less) or PM10 particles (10 microns or less).

  • PM2.5 particles are one-millionth of a meter long. Because of that, they can enter the lung air sacs and airways
  • PM2.5 particles cause the most significant health risks. Air purifiers generally remove OK PM.

Let’s learn more about household pollutants and how air purifiers might assist.

Allergens

Allergens can cause asthma, allergies, and many other respiratory diseases. The Asthma and Allergy Foundation of America reports that 8 out of 10 Americans are exposed to dust mites and 6 out of 10 to cat or dog dander.

Common indoor allergens are:

  • Pollen: These are the outdoor allergens infiltrating rooms through doors, windows, and ventilation.
  • Pet Dander: Cats, dogs, and birds release small skin flakes called pet dander.
  • Rat and mouse dander: This is like a pet dander but is more concentrated and uncontrolled. Studies reveal that 75% to 80% of U.S. houses have mouse allergens.
  • Cockroaches: Shed allergens, chitin, endotoxins, and more.
  • Dust Mite: Microbes called dust mites feed on human shed skin and flourish in humid settings. Research shows that 30% to 60% of asthmatic children come through dust mites, worsening their symptoms.

Mold

Research shows that mold can be dangerous for people with asthma and other lung disorders. Mold grows on moist surfaces and causes moisture issues. Mold reproduces by airborne spores. Mold allergies can result from inhaling or handling these spores. The mold symptoms are sneezing, throat and nasal discomfort, runny nose, and red or irritated eyes.

Smoke

Indoor smoke can originate from several sources, such as:

  • Cigarettes
  • Cigars
  • Marijuana
  • E-cigarettes
  • Vaping
  • Stoves
  • Fires
  • Idle automobiles
  • Buses

Gaseous pollutants

Indoor gaseous pollutants include:

  • Gases such as carbon monoxide, nitrogen dioxide, and ozone
  • VOCs without particles

VOCs are gaseous mixtures from thousands of organic chemical-containing items such as home products. The health consequences of these organic compounds can be harmful to or unknown.

Are air purifiers safe? Use air purifiers that use carbon or other gas-removal filters to remove gases from the air. HEPA filters are one of the most effective, as they remove VOCs, and some air cleaners target specific gases or VOCs.

Benefits of Air Purifiers

Are air purifiers safe? The benefits of an air purifier depend on its filter. These devices use CADR rate, targeted pollutants, and consistency to improve your air quality.

Here are some benefits of air purifiers:

  • Allergies: Air purifiers remove allergy symptoms which is a major health benefit.
  • Asthma: Air purifiers reduce asthma symptoms like dust, smoke, and pollen.
  • Dust: Most HEPA air purifiers can reduce dust particles to 5 microns or less.
  • Pet dander: Your air purifier may minimize pet dander from cats, dogs, and birds.
  • Particulate matter: HEPA air purifiers with high CADR can decrease indoor PM2.5 by 50% or more.
  • Viruses. Some air purifiers remove virus-laden particles. The EPA requires them to eliminate 0.1 to 1 micron particles. According to manufacturers, the air purifiers  “remove 99.9% of particles as small as 0.1 um [or microns].”

Bottom Lines

Are air purifiers safe? Yes, air purifiers work best to clean your home’s air quality, ventilate it, and control the source of contaminants. But before buying an air purifier, you should be clear on what you want it to do in your home. Know the size of the area you want to clean and the contaminants you want to eliminate. Then look at the features and lastly go for a brand new air purifier for your home.

Frequently Asked Questions

Air purifiers clean the air with filters. They pull air in, clean it with these filters, and then send the clean air out into the room. They come in different types but are usually easy to move.

No, air purifiers are different in how they clean the air. Some make ozone, some charge the air with electricity, and some use filters to catch things. Each kind has good points and bad points.

Most air purifiers are safe, but some can cause headaches or worsen asthma if they produce ozone or don’t clean well. You should pick one that suits you and is safe.

Think about what bad air you want to eliminate (like dust, pollen, or smoke), how big the space is, and what the purifier can do. Choose ones with HEPA filters for the best cleaning.

Air purifiers help lower problems from allergies, asthma, dust, pet fur, and germs. They take out bad air parts and make the air better.

For the best air, use your air purifier often. How much depends on how dirty your air is, how you stop bad air from coming in, and how you clean your home.
