Are Air Purifiers A Waste of Money?

KeyTake Aways:

  • Air purifiers may not remove 100% of all harmful particles from your indoor environment, but they can significantly reduce the presence of these particles.

Are Air Purifiers A Waste of Money?

The Environmental Protection Agency (EPA) says air purifiers can make a big difference in your home air. And science agrees! But not all air purifiers are created equal, so watch out for the ones with flimsy mesh filters. Do your research and choose wisely before you buy, so you can breathe easy knowing you got a great deal.

To determine whether air purifiers work, you need to understand how they work.

Strictly speaking, air purifiers clear (sanitize) the air of substances like toxins, pollutants, and allergens.

Unlike humidifiers or diffusers, purifiers take away particles from your indoor air.  

Additionally, some types of air purifiers filter sanitize your air by trapping the particles in their filter.

Another type of purifier is the negative ion air purifier, which attracts positive ion particles to neutralize them.

Now that we know how air purifiers function, let’s discuss whether air purifiers are effective at clearing the air. 

The truth is most air purifiers are pretty effective at purifying the air inside the confines of your home. But it’s unlikely that any purifier will remove 100% of all detrimental particles from your environment. 

This has less to do with the purifier’s efficacy and more with how particles can stick to multiple home surfaces, like bedding, carpets, walls, etc. 

However, the good news is that an air purifier can significantly reduce the aggravating particles in your living space.

In fact, purifiers can go a long way in prolonging allergy attacks and alleviating allergy and asthma symptoms.

Type Of Particles Air Purifiers Work Best For:

1. Mold

Dampness can give birth to mold particles that harm people with lung conditions or asthma.

Air purifiers with HEPA filters work best to remove airborne mold particles. 

2. Allergens

Anyone suffering from pollen allergies will tell you that allergens are no laughing matter.

Simply put, allergens are substances that can cause immune reactions like asthma or allergies.

An air purifier combined with a HEPA filter effectively removes airborne allergens. 

3. Toxins

Items such as household cleaning products or even personal care products can be the source of indoor toxins. 

Inhaling these particles can be harmful to your health and immunity. Air purifiers work to trap indoor toxins and make your private supply of air that much safer.

Perks Of An Air Purifier


Purified Air Quality: Air purifiers help eliminate pollutants, allergens, and other damaging particles from the air, which results in a cleaner and healthier indoor environment.

Healthier Breathing: By reducing exposure to pollutants and allergens, air purifiers can improve respiratory health and ease symptoms associated with asthma and allergies.

Sturdier Immunity: A purified indoor air atmosphere can strengthen your immune system, allowing you to quickly fend off illness and diseases.

Better sleep: Air purifiers can enhance the quality of your sleep by getting rid of irritants such as pet dander, mold, and dust from the air.

Less Exposure to Harmful Chemicals: Air purifiers can also minimize exposure to dangerous chemicals like volatile organic compounds (VOCs), often found in household items.

Protection from Second-hand Smoke Hazards: Air purifiers help safeguard non-smokers from the harmful effects of second-hand smoke by filtering out tobacco smoke from the air.

How Much Do Air Purifiers Cost & What Maintenance Do They Need?

Because there’s a variety of purifiers available for sale, each with its own set of features, the price of purifiers can vary.

However, if you’re searching for a ballpark range, air purifiers can cost anywhere between $70 to $1000 plus, depending on their strength and specifications. 

Maintenance-wise, air purifiers need regular filter replacement once every 3 to 6 months.

However, this figure may change depending on your usage of the product.

Also, when it comes to replacement, the type of filter the air purifier also matters. For example, usually, carbon-activated filters need to be changed more often than the primary filters.

Are Air Purifiers Worth It? What People Are Saying

As a consumer, one of the primary disadvantages of an air purifier can be the additional cost related to filter replacements.

Furthermore, if you want your purifier to function efficiently, you can’t overlook replacing its filters.

Another problem users can face in relation to purifiers is a slight impact on their energy bill.

Although, despite some popular misconceptions, purifiers can be used daily for up to 12 hours without too much power consumption. 

As a matter of fact, some air purifiers will use the same amount of energy as a light bulb on a low setting.

But, if you’re still concerned about excessive energy consumption, you can always buy an Energy Star-verified purifier that is 40 times more energy-efficient than regular purifiers.

What People Are Saying :

According to Using an air purifier can help reduce fine particles from wildfire smoke in a room and decrease the health risk from indoor air pollution

According to the EPA: Portable air cleaners and upgraded HVAC filters can help to improve indoor air quality.

According to Healthline: HEPA filters are the most effective at filtering particles, while filtered air purifiers are considered the safest type for home use.

According to The New York Times: Air purifiers with HEPA filtration efficiently capture particles.

According to The Washington Post: Because air purifiers filter airborne particles such as dander and pollen, air purifiers might work best for people with animal allergies who own a dog or cat.

Air Purifiers To Stay Away From

Stay Clear of Ozone Producers: Despite their alluring appeal, ozone generators can emit ozone which can be hazardous to inhale and cause irritation to breathing systems.

Steer Clear of Inadequate Devices: Some air purifiers readily available on the market are ineffective in trapping harmful particles. Researching and choosing a top-notch air purifier with a HEPA filter is crucial.

Don’t Fall for Unsubstantiated Claims: Be cautious of air purifiers that make big statements without any scientific backup. Always research the product before purchasing and ensure it has a reputable history of effectively purifying the air.

Avoid Non-Accredited Models: Look for air purifiers sanctioned by organizations such as the Association of Home Appliance Manufacturers (AHAM) and the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) to guarantee their efficiency and safety.

One Size Does Not Fit All: Not all air purifiers are created equal, and not all are intended for every room size. Make sure to pick an air purifier that is ideally suited to your needs.

Final Verdict:

Did you know indoor air can be around three to five times as unclean as outdoor air?

Imagine the impact of breathing dirty air at home and, to an extent, when you step out of your house.

That’s why, according to us, buying an air purifier is worth it because it positively impacts indoor air.

Aside from this, purifiers can be quite beneficial for individuals suffering from conditions like asthma, allergies, or weak lungs. 

There’s no price tag for good health, and if you’re looking to up your overall game regarding wellness, investing in an energy-efficient, top-quality air purifier is a good idea.
