Are Air Purifiers A Waste Of Money?

If you have landed on this page, you may have second thoughts on what an air purifier can do and is a waste of money. While there is zero doubt an air purifier is an excellent device that most households would need, is it worth spending hundreds of dollars on it? Perhaps more importantly, can you clean the air without relying on one? Find out the answer below.
Short answer
No, it is not.


An air purifier is not a waste of money as it can improve indoor air quality by removing harmful airborne particles. It works very well in providing clean air to the home and are worth every penny you spend on it. Without the harmful allergens in the air, allergies like cough, sinus, itchiness, dry eyes, a headache will go away, and you will live happier and healthier.

Air purifiers are recommended by doctors and can often be found in hospitals, nursery homes, schools, factories, or anywhere that needs air cleaning.

How Do Air Purifiers Work?

Air purifiers are designed to clean the air in a single room or area. HEPA air purifiers come with an internal fan that pulls air into its multi-stage filtration before circulates back clean air out. The outer Pre-filter captures large particles like dust, hair while protecting the other filter’s life. True HEPA filter traps airborne contaminants e.g. dust mite, hair, pet fur, pet dander, pollen, mold, bacteria, and viruses as small as 0.3 microns. Toxic fumes, smoke, and odors will be absorbed by an activated carbon filter instead. While an air purifier can make a big difference in the air quality, the filter will get clogged after some time. You will have to either clean or replace it according to the manufacturer’s guideline.

What Air Purifier You Should Avoid

An air purifier is the real deal, as proven time and time again. However, some models like ozone generators are downright awful and can be harmful to health. Ozonator or ozone generators produce ozone that can irritate your lungs even at a low concentration of level. Air cleaner that does not come with a HEPA filter should not be on your consideration list as well. It is not the best to deal with airborne contaminants regardless of what manufacturers are pushing.

Getting The Best Out Of Your Air Purifier

EPA does not certify or recommend a specific model, so choosing the wrong air purifier can seriously damper the air cleaning progress and make you feel it is not doing anything at all. So to ensure you are getting the best bang for the buck based on your situation, here are some quick tips when buying the RIGHT air purifier.

  • Understanding your needs - Different types of air purifiers will serve different purposes. A HEPA filter is needed if you want to reduce dust, mold, and pollen in your home. If you want to get rid of smoke, make sure the air purifier comes with an activated carbon filter. If you are an asthmatic person, you will need a more powerful asthma air purifier. Simple as that.
  • Get the right size air purifier - A very important measurement that many neglected. If the air purifier could not cope with the room size, you may not see any positive results. If you need to purify the air in a room space of 300 square feet, go for a model with that capacity. Vice versa, if you only need to purify a small area with only 100 square feet of space, go with a smaller model that is much cheaper and portable.
  • Features you are looking for - Auto mode, Sleep mode, Wi-Fi, remote control, timer just to name a few. Most of these features are more towards convenience and usability rather than performance.
  • Look at the CADR Ratings - Clean Air Delivery Rate is the official benchmark of AHAM on how much volume of the air can be clean in a controlled room. While not every manufacturer will participate in this test. We recommend air purifiers with at least 200 cfm of output.
  • Put it close to the pollution sources - For example, if you have trouble sleeping at night, place it in the bedroom. If you are allergic to your pets, place them in the area where your pets roam. Remember to leave some distance between the wall and furniture to avoid airflow disruption.
  • Energy-efficient unit - If you are worried about the cost of electricity, look for an Energy Star certified model.

What An Air Purifier Cannot Do

When the air purifier does not live up to the expectation, you will feel being cheated or let down by it. This is because of the many misconceptions and misleading advertisements circulating on the internet that set unrealistic expectations. To remedy that, let's address the common myths why some people would think an air purifier is a waste of money.

  • There is no longer the need to dust - An air purifier can only handle airborne particulates. You will still need to clean and vacuum the house to remove settled dust on the ground or wall.
  • My home will be 100% germ-free - There is no 100% guarantee as an air cleaner can only deal with bacteria and viruses in the air. It will not prevent germs spread from person to person through coughing, sneezing, or talking.
  • I can smoke indoors with an air purifier next to me - No, you can't. It can only remove secondhand smoke, NOT thirdhand smoke that has stained the wall, shirt, and floor.
  • All my allergies go away - Not all allergies are caused by airborne particles. Food, animal, and an unhealthy lifestyle are also some of the main triggers for allergy.
  • HEPA filter can trap all kinds of allergens - HEPA filter can only trap non-smoke particles (non-odor). Also, not all HEPA filters are created equal. A true HEPA filter can trap allergens as small as 0.3 microns, while a HEPA-type filter can trap down to 2 microns.
