Answer: Are Air Purifiers a Waste of Money?

In the quest for cleaner and healthier indoor air, many homeowners and consumers are turning to air purifiers as a solution to combat allergens, pollutants, and contaminants. However, the question often arises: are air purifiers a waste of money or truly worth the investment. In this article, we will take a closer look at the effectiveness, benefits, and potential drawbacks of air purifiers to determine whether they are worth the investment or not. 

Are Air Purifiers Worth It? 

According to the EPA, they’re useful since they’re an excellent way to improve the indoor air quality of your Kearney house. Newer homes are well-sealed and heavily insulated, which is beneficial to energy efficiency but not so much to indoor air quality. 

 Here are some factors to consider when making your decision:

• Health considerations: If you have allergies or suffer from asthma, using air purifiers can significantly improve your quality of life and well-being. 
• Environmental factors: Outdoor air pollution stems from various sources such as vehicle emissions, industrial processes, and natural factors. It leads to the infiltration of harmful particles and contaminants into your home or workplace. If you live in an area with poor outdoor air quality, it’s essential to consider the use of air purifiers in your indoor spaces. 

What Can An Air Purifier Do?

Whether you’re a health-conscious individual, a concerned parent, or simply someone curious about the potential of this technology, it’s time to discover why air purifiers can’t be a waste of money but are, in fact, a meaningful addition to our modern lives.

1. Decreases allergy and asthma triggers

Exposure to tiny particles can exacerbate asthma symptoms and increase medication needs. And, childhood exposure to air pollution—both particulate matter and gaseous pollution—may also increase someone’s chance of developing asthma at some point during their life. 

However, air purifiers can help reduce household allergens like dust, pollen, and mold, which can trigger respiratory conditions like hay fever and asthma. Air purifiers equipped with High-Efficiency Particulate Air (HEPA) filters are rated to remove at least 99.97% of pollen, dust, and other airborne particles 0.3 microns in size.

2. Leads to some health problem

Even if allergies or asthma aren’t a concern for you or someone in your household, an air purifier can alleviate other symptoms associated with poor indoor air quality. These include:

• Respiratory discomfort: Poor indoor air quality often leads to respiratory discomfort, including symptoms like a scratchy throat, coughing, and sneezing. Air purifiers with HEPA filters and activated carbon filters can capture and remove airborne irritants responsible for these symptoms.
• Headaches: Airborne pollutants and contaminants can contribute to headaches. By reducing the presence of these substances in the air, air purifiers can help alleviate headaches and improve overall comfort.
• Fatigue: Breathing in polluted air can lead to fatigue and a general feeling of tiredness. Clean, purified air can boost alertness and energy levels, allowing you to feel more refreshed throughout the day.
• Dizziness: Indoor air containing harmful chemicals or volatile organic compounds (VOCs) can sometimes cause dizziness. Air purifiers with VOC-filtering capabilities help reduce the presence of these chemicals, thereby minimizing dizziness.
• Nausea: Exposure to indoor air pollutants, especially in tightly sealed or poorly ventilated spaces, can lead to feelings of nausea. Air purifiers help by continuously filtering the air, reducing the concentration of pollutants and alleviating this discomfort

Actually, it can be tricky to distinguish troubles associated with indoor air quality, since they can be linked to lots of other illnesses. However, if you’re aware that symptoms are better after you leave home, your indoor air quality is likely causing the issue.

3. Removes odors

We see that air purifiers are not only effective at removing airborne particles and allergens but also excel at eliminating unpleasant odors in indoor spaces. Unwanted odors can originate from various sources, including cooking, pets, smoke, or even household chemicals. 

Air purifiers equipped with activated carbon filters or other odor-removing technologies are specifically designed to address this issue. These filters are porous and have a large surface area, allowing them to trap and retain a wide range of volatile organic compounds (VOCs) responsible for odors.

4. Decrease your probability of being sick

An air purifier, when operating under specific airflow conditions, can render certain bacteria and viruses inactive. Therefore, it helps to maintain the well-being of you and your family, especially in the winter season. Here’s how air purifiers contribute to better health and a decreased likelihood of getting sick: 

• Removal of viruses and bacteria: Some air purifiers are equipped with ultraviolet (UV) or UV-C germicidal lamps that can target and neutralize viruses and bacteria in the air. By reducing the concentration of these pathogens, air purifiers help lower the risk of respiratory infections.
• Mitigation of mold spores: Mold spores are common indoor allergens and can also contribute to respiratory issues. Air purifiers can help reduce mold spore concentrations, which is particularly important for those with mold allergies.
• Enhanced sleep quality: Better indoor air quality, achieved through the use of air purifiers, can lead to more restful sleep. Quality sleep is essential for maintaining a strong immune system, making you less susceptible to illness.

To fully leverage this benefit, we suggest the use of a UV air purifier. Ultraviolet light disinfection adds an additional level of protection against airborne pathogens.

5. Reduce dust and dust mite accumulation

We additionally realize that continuous exposure to household dust mites can significantly affect your well-being. Symptoms include:

• Runny nose
• Watery eyes
• Sneezing
• Coughing
• Congestion
• Facial discomfort

According to the American Lung Association, dust mite exposure can contribute to asthma. Air purifiers, particularly those equipped with HEPA filters, capture and trap even the smallest airborne particles, including dust and dust mite allergens. By removing these particles from the air, air purifiers significantly reduce dust levels in the environment.

What Can’t An Air Purifier Do?

While these devices have proven themselves as effective tools for improving air quality in many scenarios, we still see their limitations and discern when investing in one may not be the most cost-effective choice. Let’s uncover the reasons why air purifiers are a waste of money and when they might not be the best use of your resources.

1. It can’t keep your home free of all types of viruses

Although an air purifier is effective in eliminating germs from the air, it operates solely within the room where it’s placed. Unfiltered air in other areas of the house may remain unaffected. We can say that air purifiers are just one part of a comprehensive strategy for maintaining a clean and healthy home. It’s important to combine their use with other hygiene practices and preventive measures to minimize the risk of illness, such as:

• Regular hygiene practices (Thorough handwashing, cleaning and disinfecting surfaces)
• Take precautions to prevent the introduction of germs into your home. 

2. It can’t reliably filter out dangerous chemicals

Air purifiers can be effective at removing a wide range of dangerous chemicals from the air, but it’s important to note that they may not be able to filter out all types of chemicals reliably. This is because some chemicals are very small or have a low boiling point, making them difficult to capture. Additionally, some chemicals may react with the filters in an air purifier, reducing the effectiveness of the filtration process.

Chemicals that can be challenging for air purifiers to remove include:

• Volatile organic compounds (VOCs): VOCs are a large group of chemicals that are found in many common household products, such as paint, furniture, aerosol sprays, and cleaning products. VOCs can have a variety of health effects, including irritation of the eyes, nose, and throat, headaches, and nausea. Prolonged exposure to VOCs can also damage the liver and harm the central nervous system.
• Formaldehyde: Formaldehyde is a colorless, flammable gas that is used in a variety of industrial and commercial products, such as plywood, adhesives, and insulation. Formaldehyde is also a known carcinogen.
• Nitrogen dioxide: Nitrogen dioxide is a reddish-brown gas that is produced by the combustion of fossil fuels. Nitrogen dioxide can irritate the lungs and aggravate respiratory conditions such as asthma.

What Kinds of Air Purifiers to Avoid?

While air purifiers can provide benefits, it’s equally important to discern between the effective and the ineffective. Join us as we take a closer look at the types of air purifiers that are a waste of money to buy, helping you make informed choices when it comes to your indoor air quality.

1. Air purifiers with ozone generators

Air purifiers designed for residential or office use and equipped with ozone generation operate based on the principle of corona discharge. In this process, the air purifier emits ozone molecules that bind to other fine particles found in indoor air, leading to their disintegration, a chemical reaction known as oxidation. This process has three significant detrimental effects on indoor air quality, which is:

• Produces ultrafine particles that can enter the bloodstream, cause heart issues and respiratory difficulties, and hinder the growth of young children.
• Is a time-consuming process, taking an extended period to cleanse the air, even in a small room thoroughly.
• Can lead to an excessive accumulation of ozone gas within the room, surpassing recommended safety levels by up to 5-10 times. This can trigger severe health problems, especially for children and pets.

2. Purifiers without activated charcoal bed

H13 HEPA filters are highly effective at eliminating 99.9% of particles like pollen and dust, even down to 0.1 micron. Nevertheless, they are not equipped to handle the removal of chemicals, gasses, or odors. For this purpose, it is imperative to have an air purifier that incorporates an activated charcoal bed filter. When an activated charcoal filter is combined with HEPA filters, it maximizes the removal of particles, chemicals, and odors from the indoor air, thereby enhancing air quality. Additionally, the activated charcoal filter exhibits a greater capacity for trapping harmful particles.

3. Personal air purifiers

One of the primary drawbacks of personal air purifiers is their limited capacity. These devices are typically small, often resembling a pendant or a small handheld fan, and they are only capable of purifying a small volume of air. This means that they can only clean the air immediately surrounding the user, within a very limited radius. In other words, personal air purifiers are only effective at cleaning the air you directly breathe in, and they are unable to address the air quality in larger spaces, such as homes or offices.

4. Air purifiers with UV-C light

One of the primary concerns with UV-C air purifiers is the potential harm they can pose to your health if you are exposed to the UV-C light directly. Prolonged exposure to UV-C radiation can be harmful to your eyes and skin, causing damage and increasing the risk of skin cancer and cataracts. 

Another concern associated with UV-C air purifiers is the potential production of ozone. Some UV-C purifiers, when not designed correctly, can generate small amounts of ozone as a byproduct. Ozone can be detrimental to respiratory health, especially for individuals with asthma or other respiratory conditions. 

4 Vital Things to Consider When Buying Air Purifiers

Now, you have the answer to the question: are air purifiers a waste of money or not? It’s time to consider how to choose the right one.  We will explore the four vital aspects that you must take into account when purchasing an air purifier: 

1. Air circulation and filtration

Air circulation and filtration are both important for air purifiers to work effectively, so you need to look at these factors thoroughly before buying. Let us explain more specifically about each factor:

• Air circulation: Proper air circulation is a key factor in the effectiveness of an air purifier. Adequate air circulation allows the purifier to capture and remove a broader range of pollutants from the room.Thereby, it is critical to:
  • Look for air purifiers with multiple air intake and outflow vents, as this ensures a more thorough circulation. 
  • The device should have a fan or blower that can effectively move air through its filtration system.
• Filtration technology: Different air purifiers employ various filtration methods to target specific pollutants. The filtration system should align with your specific needs and concerns. Common filtration technologies include:
  • HEPA (High-Efficiency Particulate Air) Filters: Highly effective at removing small particles like dust, pollen, and pet dander.
  • Activated carbon filters: Ideal for eliminating odors, gasses, and volatile organic compounds (VOCs).
  • UV-C Light: Effective at neutralizing bacteria and viruses.
  • Electrostatic precipitators: Use electric charges to attract and capture particles.

We encourage you to consider your specific requirements when selecting a purifier’s filtration technology. For example, if you suffer from allergies, a HEPA filter might be a priority. For odors and chemicals, activated carbon is essential.

2. Size and coverage

Opting for an air purifier that is undersized for a room will result in the air remaining unrefreshed and inadequately filtered. Conversely, selecting an air purifier that exceeds the room’s needs will lead to unnecessary energy consumption and occupy surplus space, necessitating careful consideration of its placement.

Many air purifiers are assessed based on their Clean Air Delivery Rate (CADR), a standardized metric maintained by the Association of Home Appliance Manufacturers. The CADR quantifies, in cubic feet, the volume of specific airborne particles like dust, pollen, or smoke that the purifier can effectively remove from the air. Essentially, it serves as an indicator of an air purifier’s efficiency in cleansing the air within a given room, with larger rooms requiring air purifiers with higher CADR ratings.

3. Features and maintenance

The features of an air purifier can greatly enhance its performance and convenience. Here are some key features to consider:

• Filter change Indicators: These indicators alert you when it’s time to replace the air filters, ensuring that your air purifier operates at its best. This feature helps you maintain optimal air quality.
• Programmable timers: Timers allow you to set specific operating schedules for your air purifier, saving energy when you don’t need it and ensuring it’s running when you do.
• Air quality sensors: Air purifiers equipped with sensors can automatically adjust their performance based on the detected air quality. This feature is especially useful for maintaining consistent air quality without constant manual adjustments.
• Quiet mode: If you plan to use the air purifier in a bedroom or a quiet workspace, a quiet mode can be invaluable. It reduces noise levels for a peaceful environment.

Besides, the filters need to be replaced periodically, so it is important to:

• Ensure that the air purifier you choose has readily available and reasonably priced replacement filters.
• Check if the device provides filter replacement indicators or reminders to help you stay on top of maintenance.

4. Your specific needs

Suppose you or your family members suffer from allergies or have sensitivities to airborne allergens like pollen, pet dander, or dust mites. In that case, you’ll want an air purifier with a High-Efficiency Particulate Air (HEPA) filter. HEPA filters are highly effective at capturing even the tiniest allergenic particles, providing significant relief from allergy symptoms.

However, for situations where smoke and odors are a concern, such as cooking odors, cigarette smoke, or pet smells, consider an air purifier equipped with an activated carbon filter. These filters excel at adsorbing and neutralizing odorous particles and chemicals, leaving your indoor air smelling fresh.
