What is an air purifier and how does it help you breathe better?

Air Purifier? How Do They Work?

An air purifier is a device that filters dirty air in order to generate clean, filtered air.

After the dirty air has been purified, the cleaned air is then released into your home or office. Air purifiers can reduce dust mites and allergens, improve indoor air quality, and help prevent the spread of germs.

What Is An Air Purifier

An air purifier is a device that senses the level of air pollution in your home or office and instantly begins to clean your air by removing particulates, smoke, gases and other pollutants.

These pollutants can be produced by various sources such as cooking, cleaning, smoking tobacco products or marijuana. Air purifiers are capable of cleaning the air in homes and offices up to 30 feet away from the appliance.

How Do They Work?

Air purifiers are able to completely eliminate airborne particles such as dust mites by using a series of built-in filters.

You may or may not have all of these on your Air Purifier. If you don't, you can still use your Air Purifier as long as you activate the air purifying filter by plugging it in.

The air purification process begins when power is supplied to the unit by connecting it to a household outlet. The carbon pre-filter will capture particles from the air as they enter the unit. As the pollutants are collected, they will be sent through an electrostatic filter.

This removes large airborne particles before they enter your home or office. The HEPA filter that's built into each air purifier will remove any remaining particles that pass through this first filter.

Where Are They Used?

Air purifiers are used in people's homes as well as in many businesses, such as pet stores, grocery stores, hospitals, doctors offices and grocery stores. These appliances help those who suffer from allergies to pollen or dust mites to breathe clean air.

In addition, the air purifier will make the entire environment safer by creating sanitary conditions for all who visit your place of business or live in your home.

The air purifier and allergies

Allergies are caused by inhaling certain airborne particles known as allergens. These particles can cause itching, sneezing and other symptoms in people that suffer from allergies. If you live with a person that suffers from allergies to dust mites, tar particles, pollen or mold spores, your home may be filled with these allergens. One of the best ways to eliminate airborne allergens is by using an air purifier.

The air purifier and asthma

Asthma is a breathing disorder that causes the respiratory system to work improperly. It is characterized by coughs, wheezing sounds that are usually in short bursts, asthma attacks and reduced lung capacity.

This condition occurs when mucus production in the lungs causes inflammation of the airways which results in an inability of the lungs to effectively get air into or out of the body with enough force to sustain life.

The air purifier and cats

Cats are notorious for creating a large amount of allergens and dust mites in your home on their fur. Since cats groom themselves to remove excess hair, they have a higher likelihood of spreading these allergen-bearing mites while grooming themselves.

Some people have cat allergies as well, so it is important to eliminate all of these allergens from your home. Air purifiers can be used to reduce the amount of these allergens in your home by filtering out the particles that are attached to the cat's hair while cleaning the air.

The air purifier and dogs

Dogs also shed large quantities of allergens and dust mites. They spread these allergens as they move about your home or office. These allergens are also present in pet food, so you may be allergic to your own dog if you have one in the house.

The air purifier and tobacco smoke

Secondhand smoke is harmful to your health because it contains nicotine, tar, carbon monoxide and other harmful chemicals that can cause health issues for you and those around you. The best way to remove all of these pollutants from the air in your business or home is by using an air purifier that will filter out all of these pollutants and destroy them before they can enter your body.

The air purifier and cooking

Cooking food creates particulates in your home that are released into the environment when you cook food on a stove top, use an oven or broil food directly over a flame. These particles can be irritants if you suffer from allergies, so you should use an air purifier when preparing meals for yourself and your family members.

The air purifier and pollution

Pollution is the accumulation of dust, dirt and other particles into the atmosphere caused by wind movements, foot traffic, construction and other activities that stir up dirt. Using an air purifier will prevent these pollutants from accumulating into your home or office.

The air purifier and mold

Mold is a type of fungus that can grow in warm, damp places. It is a common cause of allergy symptoms such as slime, sneezing, rash and headaches. Mold spores are dispersed through the air by many different means, including humidity and wind drafts.

Many people are allergic to mold, which can be a cause of asthma, allergy symptoms and other ailments. Air purifiers will remove the mold and other allergens from your home or office.

The air purifier and cleaning products

Cleaning products are used to get rid of dust, dirt, grime and mold from your home or office. These products can also contain harmful ingredients that may trigger allergic reactions in many people. Some cleaning products are also irritating to your lungs if you have asthma or allergies.

Air purifiers are capable of removing pollutant particles as well as synthetic chemicals when cleaning or polishing surfaces in your house so that allergen-laden particles do not become airborne through the use of these products.

The air purifier and dust

Dust is a common source of allergens. There are many different types of dust, including dust mites, pollen, animal dander and mold spores. The best way to reduce dust in your home is by using an air purifier that will capture the particulate matter in the air before it can accumulate on your walls, furnishings and flooring surfaces.

The air purifier and pollen

Pollen is a common allergen that can cause allergic rhinitis, hay fever and asthma symptoms. Pollen can be present in the air before you even enter your home or office. It is caused by flower blooms released by trees, plants, weeds and grasses that create microscopic plant seeds that float in the air as tiny dust particles. An air purifier will remove allergens before they will cause you to suffer from an allergy attack.

The air purifier and animal dander

Animal dander also known as pet allergens is a type of allergen believed to be responsible for causing allergic rhinitis, eye allergies and asthma symptoms along with other conditions. Animal dander is created by animals including cats, dogs, mice and guinea pigs.

Pets have hair follicles that produce allergens which cling to their fur. If you own any pets and suffer from allergies caused by animal dander, it is recommended that you use an air purifier to remove these allergens before they become a problem for you.

The air purifier and birds

Birds that have been kept in cages can produce allergens that cling to their feathers. If you let your birds fly freely in your home or office, they can also create a fine dust that contains feather allergens. This fine dust floats in the air and settles on the walls, furniture and other surfaces. An air purifier will remove these allergens before they cause problems for you.

The air purifier and toxins

Toxins are created by many different means, including pet urine, paint fumes, chemical cleaners and cigarette smoke. Air purifiers are able to remove these toxic particles from your home or office so that you do not inhale them into your lungs.

What To Look For In An Air Purifier

When shopping for an air purifier, there are some important characteristics that you should look for. These include the following:

Ease of Use:

Ease of Use of an air purifier is important. It should be easy to use and simple to install. The instructions should clearly explain how to safely use the air purifier as well as any restrictions that should be followed.

Filter Type:

The filter type that you choose will depend on your home or business needs and the size of your home or office space. This is particularly important if you have a high number of animals or are anticipating a large increase in dust particles in your area. You may need more than one filter depending on the amount of dust that accumulates in your area. Cost:


Cost can be a factor in choosing an air purifier for your home or office. Air purifiers that are higher priced are more effective at removing pollutants from the air. You may want to choose an air purifier that is within your budget or you may want to choose a more expensive model depending on the amount of pollutants that you will need to remove from the air in your home or office space.

Power settings:

It is important for an air purifier to be able to clean the air effectively, but it is also important that you can lower the volume of noise emitted from the purifier. Look for a device that has a built-in power setting or a remote that will allow you to set a quieter setting depending on the noise level in your area.

Air Cleaner (Fan):

The air cleaner in an air purifier is an important feature that will determine how well it will remove particles from the air. Air purifiers typically have either a fan or a HEPA filter designed to remove airborne pollutants.

The more effective and powerful the filters, the better they will be at removing particles. Consider the quality of the filter or filer when you are deciding what type of air purifier to purchase.

Types of Air Purifier

There are many different types of air purifiers out there, and they each have their own advantages and drawbacks. The various types of air purifiers are:

Passive air purifiers

which do not require power to operate quite like a fan. These units are extremely quiet and produce little to no noise. You can find these devices almost anywhere, from hardware stores to electronics stores. They are the most affordable option on the market.

HEPA filters

are a filter that is used in many air purifiers today. This is a filter that traps hair and other large particles from your home or office in order to keep them from entering the air that you breathe. These filters are 99.97% effective at trapping pollutants.

Electrostatic air purifiers

are another type of technology that uses a collection plate. A fan blows air across the plate which traps dust and other particulate matter so you do not breath it into your lungs.

Activated carbon /charcoal filters

These are air purifiers that work in a similar fashion as a smoke removal system. This filter is able to trap the odor molecules in the air so that you do not smell the unpleasant smells from your home or office. These filters are also used to reduce cigarette smoke, pet odors and other unpleasant smells. These units have HEPA filters as well that will remove 99% of airborne particles from your home or office.


Ionizing air purifiers use a small electric fan to fling charged particles toward the plate. The fan will remove odors as well as viruses, bacteria and other microbes. These units are a little more expensive than HEPA filters and electrostatic filters but they are very effective at removing pollutants from the air.

Ultraviolet (UV) light air purifiers:

Ultraviolet light air purifiers use UV lights to kill microorganisms in the air. These microorganisms include mold, mildew and viruses. These units are very effective at killing these microbes and will keep you from breathing them into your lungs. These units are more expensive than other kinds of air purifiers.

Are air purifiers a waste of money?

No, air purifiers are definitely worth the investment. Although air purifiers are not a necessity and you can breathe just fine without one, they do save you money in the long run and help to keep your home or office environment healthy. If you suffer from airborne allergens or pollutants in your home or office, you will have an increase in health issues like asthma.

You may think that you do not need an air purifier and that the air is fine, but when it comes to allergens, chemicals and pollutants everything changes.

How long does it take for an air purifier to clean the air?

30 minutes to 2 hours, this will depend on how big the room is, what is in the room and the size of the Air Purifier.

What is the average lifespan of air purifier filters?

The average life of an air purifier filter is about 6 months, then you will need to buy a new filter. You may notice a decrease in effectiveness of your filter after 6 months or it may be less time than that. The more you use the unit the sooner you will need to replace its filters, this will all depend on how much dust and other pollutants are in your home or office.

Better Overall Health With An Air Purifier

Air purifiers are very useful for people who have asthma, allergies and other breathing conditions. When you use an air purifier, you are able to breathe easier, which is why they can be a necessity in your home or office space. There may be an increase in dust particles and pollutants in your area that you cannot see with the naked eye that can be hazardous to your health and make you uncomfortable.


Air purifiers do work and are very helpful in the long run, this all depends on what kind of pollutants you have in your home or office space. If you have quite a lot of dust particles and other pollutants in your space, you may notice an increase in dust and other airborne particles at times.

You should not rely on a single air purifier but look for multiple units that will work together to help clean the air in your home or office space. In this way you will be able to create more air circulation throughout your home or office which helps to keep it clean.
