What To Look For In A $50 Air Purifier?

When choosing an air purifier for your home, office or car it is important to understand what the product is designed to do and how it performs those tasks. To help you in your search, we've outlined the most important things to look for in a good air purifier. The following factors should be considered when purchasing an air purifiers. However, for $50 you will not be able to get most of the following:

Ease of Use:

While some air purifiers may require a few minutes to get used to the controls, others may come with easy-to-follow user manuals. If you plan to use your product regularly it is important that the controls are easy to use and don't require any special expertise or skills to operate.

Power settings:

Another key feature of any air purifier is how it adjusts its power settings. The higher the power settings, the faster air is filtered and circulated. However, some purifiers only have a few power settings while others may have a range of options for different situations (such as sleepy time or for more active kids).

Air Cleaner (Fan):

The air cleaner "sweeps" the air through the filter, releasing particles from the air. Power settings and air flow can be controlled with the movable dials on top.

Air Filters:

Air purifiers may use one, two or three filters depending on the type of particle being removed. Different types of filters have different natural materials used to remove different types of particles. Activated carbon/charcoal filters are effective against smog and airborne bacteria, while HEPA filters are used to remove allergens such as dust mites and other harmful particles.


Air purifiers do not replace the need for fresh air, they simply introduce it into your home or office. The amount of ventilation required to properly ventilate your home will vary depending on the size of your space as well as how many people will be occupying it.

Only a few air purifiers include this feature, however these systems are widely used by hotels and other places that require constant temperature control of rooms. Air purifiers with cooling can prevent mold and bacteria growth in closed spaces and some may remove heat from a room that is too warm.

Types of Air Purifier For $50

However, it is also important to know how it collects particles, how many types of particle removal the filter uses and whether or not the product is effective on odors. You may want to keep an eye out for:

True HEPA filters

With true HEPA filters, 99.97% of particles as small as 0.3 microns (or in some cases even smaller than that) are trapped by the filter, compared to only 99% for imitation HEPA filters.

Activated carbon /charcoal filters: are made from a material that absorbs, traps and neutralizes airborne substances such as smoke, pet dander and other odors.


This type of air purifier may have a fan that ionizes the air by releasing negative ions into the room. These ions attach to unwanted particulate in the air and destroy them. The problem with ionizers are that they do not remove particulate matter but only attract it. As a result, these types of purifiers may be more expensive than others because they need to be used in conjunction with another type of filter or sometimes even an ozone generator for odor control.

Ultraviolet (UV) light :

Air purifiers that use UV light are designed to kill microorganisms such as mold, mildew and bacteria. These lights are not safe to use around humans and should only be used in enclosed areas such as a garage or bathroom where there is no need for constant air circulation.

Electrostatic air purifiers :

These types of purifiers are used to remove dust, pollen and other small particles from the air. Electronic particles are neutralized by being attracted to a charged surface and then trapped by a filter. The problem with electrostatic air purifiers is that they don't remove large particles such as pet dander or humidifying pollutants, so they need to be cleaned on a regular basis.

Ozone generators:

Ozone generators create ozone (O3), which kills microorganisms in the air by breaking down cell walls through oxidation. Some experience mild irritation from these types of purifiers, however they can be effective for removing odor or for spaces that require constant temperatures such as hotel rooms.

Type of Pathogen For A $50 Air Purifier

Air Purifiers can keep the following at bay:


Allergens are an airborne particle that has the potential to cause an allergic reaction. Common allergens found in air purifiers include dust mites, pollen and pet dander. The presence of these allergens is especially problematic for people with asthma because they can make their symptoms worse.


Pollen is a type of allergen that is produced by plants and often comes from outdoor environments such as parks, golf courses, forests, etc. Pollen can trigger allergic reactions in people who are susceptible to them due to allergic rhinitis and other conditions. Allergens can also cause asthma symptoms such as shortness of breath and wheezing.

Dust mites

Dust mites may seem unimportant but they are a common indoor allergen. These small insects produce the potent allergen called Dermatophagoides farinae which is toxic to humans and animals alike. They also produce saliva that contains enzymes that break down human skin proteins, causing irritation in sensitive individuals. These allergens can be found in most bedding, furniture and carpets.


Mold is a type of allergen that produces the potent allergen called Histamine. This naturally occurring substance is known to cause allergy symptoms such as increased breathing difficulty (coughing), sneezing, itching, tingling and dry skin. Mold can also trigger asthma symptoms such as shortness of breath and coughing.


Bacteria are microscopic organisms that cause diseases and respiratory illness in humans. Common types of bacteria that may be found inside a home or office are E. Coli and Salmonella. Studies have shown that these microorganisms can cause symptoms such as asthma, bronchitis and pneumonia.

Fungal spores. Fungal spores are the most problematic type of pathogen found in air purifiers due to their thriving ability outside of a host organism. These microscopic spores are often found in carpeting, furniture, insulation and air ducts which makes them an ideal area to start an infestation of fungal spores.


Smoke is a type of allergen that comes from cigarettes, cigars, wood burning stoves and other sources of combustion. The smoke may contain carbon monoxide which is toxic to humans and can cause severe respiratory illnesses such as obstructive lung disease or acute bronchitis.


Viruses are infectious agents that are split into two sub-groups: RNA or DNA viruses. These viruses often enter the body through the mucous membranes in the mouth through inhalation or direct contact with infected blood. Viruses can cause illness symptoms such as fever, cough, nausea and vomiting when inhaled into the lungs.

Pet Odor

Pet Odor is a type of pathogen that can cause illnesses and exacerbation of asthma symptoms. Pet dander is the airborne particles of dead skin cells and hair from animals. Pet dander can cause allergic rhinitis, exacerbating allergic asthma symptoms and causing respiratory symptoms such as coughing, wheezing, shortness of breath and shortness of sleep.


Odors are also a type of allergen which can be produced by food spoilage and smoking in the environment. The smell may be caused by bacteria growing in mold or by chemical reactions between sulfur compounds in various materials such as wood, lavatories, synthetic materials or other substances found around the home such as plastic bags or carpet padding.

Better Overall Health With A $50 Air Purifier

Getting a $50 Air Purifier can still be a money-saver and can be a good choice to make. However, you still want it to be the best it can be. Cleaning is the key to that, and making sure you have a deep clean is something that you will want to do periodically. The filters can be costly, so I recommend you get one that will last you at least a year, or 2-3 years if you are more of a heavy user.

The best way to go is with the regular disposable filter every 6 months, though it may be more cost effective to purchase a reusable filter and replace them often. You'll save money on replacement costs in the long run. For those people with very heavy usage of air purifiers, do take note that the lifespan for them is not always guaranteed.


Choosing the best air purifier can be confusing at first, and there are a ton of them out there. You can find cheap ones, but they won't always work as well, so you may end up spending more in the long run because you have to replace it. It's better to get something with a great warranty, and something that will be able to run 24/7 if needed.

There are quiet models too so that won't interfere with your family and neighbors. Whatever you choose, make sure you take the time to research the brand, and find out what's available. You don't want to be stuck with something that will have you throwing it away in a few months.

Other Questions

Do we need air purifier at home?

When at home , it is best to have a 2 in 1 air purifier and fan. These will help with the changes you feel that cause your asthma. They will also help in air quality, which is an important part of the breathing process, as well as cleaning the air for those who are sensitive to molds or dust.

It really can't hurt to have one of these at home, especially if it's not having any negative impact on your health, like allergies or mold.

Should I leave my air purifier on all the time?

If you are using an air purifier, it is best to leave it on when you are awake and at home. It will help you breathe better. However, if you need to be asleep and your air purifier is loud, I recommend turning it off. You can always turn if back on in the morning before you get out of bed.

Are Air Purifiers Safe?

Air purifiers are just as safe as any other appliance in your home. You don't want to put it anywhere that kids can reach or tamper with, but they won't hurt them at all once they have turned into an adult. Air purifiers have so many uses outside of your home, too.

You can use them to help clean the air before or after a pool party, or in any situation where you want to leave your house and enjoy the fresh scent of the air. Just make sure that you are purchasing one that is reputable and will last you a long time so that it isn't getting rid of so much dust, mold, bacteria and anything else that could lead to asthma symptoms.

Air purifiers work best on high traffic areas where everyone is constantly in and out or in an environment where there are open windows for fresh air to circulate.

Should I buy only an air purifier?

If you have a need for a complete cleaning solution, it would be wise to purchase an air cleaner. They are designed to help clean all the air in your home on a daily basis and help you breathe better as well.

However, if you are just looking to have a problem with house dust or molds due to someone being sick and carrying germs in your home, they can be beneficial for that as well. An air purifier will remove some of the things that cause allergies but will not remove all of them from your home or office so should only be used when necessary.
