Save Money: Are Air Purifiers a Waste of Money?

Many wonder if air purifiers are worth the money or just fancy gadgets. The EPA says air purifiers can reduce airborne contaminants, proving their worth.

I’m an HVAC expert with allergies and pets. Recently, I noticed the air quality in my home got worse. My friend Ben, who studies Environmental Science, suggested I buy an air purifier. After using it for three months, I want to share my thoughts.

Studies from the EPA also show that air purifiers can cut indoor pollution but can’t remove everything. This matters a lot if you have pets, smokers, or live in a polluted area. In this article, we’ll find out: Are air purifiers a waste of money, or are they really good for your health and home?

How Does an Air Purifier Work?

An air purifier improves the air in a room by using filters to clean it. What do air purifiers do? They have HEPA filters that capture nearly all tiny harmful particles like dust and pollen, being 99.7% effective. They also use charcoal filters to remove gases and odors. The machine pulls air in, cleans it with these filters, and then sends fresh air back out. However, they don’t remove viruses or gases well. Viruses are often too small, and gases need different methods to clean from the air.

The EPA says air purifiers help but should be used with other methods like good ventilation and source control for best air quality.

Common Pollutants Targeted

Air purifiers work to clear a few main irritants from our air:

  1. Particulate Matter: This term refers to very tiny particles, such as dust, smoke, and pollen. These particles, when breathed in, can harm our hearts and lungs.
  2. VOCs (Volatile Organic Compounds): These are harmful gases and odors from common items like spray cleaners and paints. Air purifiers need activated carbon filters to remove VOCs, as not all can catch these gases.
  3. Allergens: These include things like pet dander and mold that can cause allergies. HEPA filters in air purifiers are great for trapping these particles. Remember, allergens include more than just those, like dust mite debris and some fungal spores.

Benefits of Air Purifiers

Are air purifiers worth it? Think about their role in making air cleaner and how this helps health, especially in homes with lots of pollution or allergens.

Advantages of Using Air Purifiers

Preventing Allergies

About 30% of adults and 40% of kids in the U.S. have allergies. Every year, over 50 million people deal with this issue, making it the sixth most common chronic illness in the country. These allergies cost U.S. healthcare and businesses around $18 billion each year. Source: WebMD.

Air purifiers with HEPA H13 filters are great for stopping allergies. They pull in air and trap tiny bits like pollen, dust, and pet hair. These filters catch about 99.97% of tiny 0.3 micron-sized particles.This makes the air cleaner and helps people with allergies feel better. 

A study in the Yonsei Medical Journal looked at how air purifiers with HEPA filters help adults with allergic rhinitis. They found that using the purifiers for six weeks really helped reduce the need for allergy medicines and dust in homes.

“I used to sneeze a lot because of my allergies. I have pets and tried many things, but only got a little better. Then I bought a big air purifier for my home. It helped a lot! My allergies are not gone, but I feel much better now. From really bad to okay!” — u/ThiccBacon

Reduces Odors

Common smells like cooking, pet odors, or musty rooms can make your home less welcoming. Air purifiers use special filters like activated carbon or charcoal to remove odors and gases from the air. What do air purifiers do in this case?

These filters are great at getting rid of common household smells like those from pets, cooking, and smoke. Breathing clean air cuts down on things that can cause breathing problems, headaches, and allergies. It also reduces harmful chemicals like VOCs in your home, making your space safer and more comfy.

In my home, we have pets, and sometimes the smells can be overwhelming. After getting an air purifier, I noticed a big change. The pet odors were much less noticeable, and the air felt fresher. Even the lingering smell from cooking was reduced.

Improves Sleep

If cigarette smoke or cleaner fumes at night disturb your sleep, a calm bedroom with soft pillows won’t help. These airborne pollutants can disrupt your rest.

At night, when you’re trying to relax, you might start noticing the day’s buildup of cooking smells and cleaning chemicals. Sleeping in a room with these pollutants for over six hours can make it tough for your body to refresh itself, affecting your health and sleep.

An air purifier with a HEPA filter can clear the room of smoke and chemical fumes, improving your sleep. Research shows that HEPA filters increase total sleep time by about 12 minutes per night and enhance air quality.

Can Increase Life Expectancy

According to a University of Chicago report, air pollution reduces global life expectancy by 2.3 years. Another study shows indoor air pollution cut life expectancy by 0.7 years in 2019.

Air purifiers help us live longer by cleaning our air. They take out bad stuff like smoke, dust, and fumes. This means less breathing trouble and other health issues from dirty air. Clean air can make you healthier and help you live a longer life.

Key Features in Air Purifiers

There are some essential factors that need to be considered when buying an air purifier. They are: 

CADR Rating: CADR – Clean Air Delivery Rate , It’s very important because it shows how quickly an air purifier can remove dust, smoke, and pollen from the air. A higher CADR rating means the purifier is better for larger rooms, as it can clean more air faster.

Filter Types: Air purifiers have different filters for different jobs. HEPA filters are super at catching tiny things you can’t see, and activated carbon filters are champs at soaking up smells and gases. It’s like having a special cleaning tool for every kind of mess in your house.

Size: Make sure the air purifier fits the room. A small one won’t do much in a big space, similar to how a small fan can’t cool a large room well. 

Noise Level: Since you’ll likely use it in places where you relax or sleep, think about how loud it is. Some are so quiet you hardly know they’re there, while others can be pretty noisy.

Personal Experience

When I was shopping for an air purifier, I looked at the CADR rating first. I needed one that could handle my living room, which is pretty big. I also made sure it had a HEPA filter because of my allergies. The noise level was a big deal for me too. I found one that was super quiet, so it didn’t disturb my sleep. This made a huge difference in my home’s air quality and my overall comfort.

Drawbacks of Air Purifiers

Air purifiers have many benefits but also some downsides. Here are the main cons:

  • Cost of Air Purifier: Air purifiers can be costly. Basic ones start at around $100, and high-end models can cost over $800. Yearly, replacing filters might add $20 to $100 to your expenses. This makes them a bigger investment over time. When I bought my first air purifier, I was surprised by the ongoing costs. The initial price was high, and replacing filters added up quickly.
  • Noise of Air Purifier: Air purifiers make some noise. The quietest ones sound like a whisper, and the louder ones sound like a busy office. This noise can be around 30 to 70 decibels. Sometimes, the noise bothered me, especially at night. I had to move it further from my bed to sleep well.
  • Ozone Production: Some air purifiers release ozone, which can irritate your lungs and is harmful to your health. This happens especially with ionizers and ozone generators. I learned that my ionizer model produced ozone, which wasn’t good for my allergies.
  • Limited Range: Air purifiers usually only work well in one room. They can clean spaces from 100 to 1,500 square feet, depending on their design. For a whole house, you might need more than one. I found out that one purifier wasn’t enough for my whole house, so I had to buy another one for the living room.

Despite these downsides, the cleaner air made it worth the effort and expense.

Ineffective Air Purifiers

When considering ways to improve our homes and make the air cleaner, air purifiers often come up. It’s helpful to know when an air purifier might not be useful or even necessary. An air purifier might be considered a waste of money in a few situations:

  • Well-Ventilated and Low Pollution Areas: If the air around you is pretty clean and your home gets plenty of fresh air, an air purifier might not make a big difference. Fresh air from outside can naturally make indoor air better by pushing out bad air. I live in a clean area with lots of windows, so sometimes, just opening them makes the air feel fresh without needing an air purifier.
  • Misjudging the Purifier’s Capacity: Buying an air purifier that’s too small won’t clean your air well. And if it’s too big, it could use up more electricity without doing much more for you. I once bought a small purifier for my large living room and noticed no difference. I had to upgrade to a bigger one, which cost more but worked better.
  • Overestimating Capabilities: Thinking an air purifier will remove all odors and particles may disappoint you. These devices are made to reduce, not completely clear, pollutants. I thought my purifier would get rid of all cooking smells, but some still lingered. It did help a lot, but it wasn’t perfect.
