How Well Purifiers Work

Do air purifiers really work? This is the primary question asked by every potential buyer. Yes, air purifiers really work to a great extent. They filter the air through multiple layers of filtration equipped with modern technology. A good air purifier comes with at least a three-stage filtration system comprising a pre-filter, an activated carbon filter, and a true HEPA (high-efficiency particulate air) filter. if you want to save your money you can buy air purifier with washable filter.

The pre-filter traps comparatively larger particles, the carbon filter removes different odors, and the HEPA filter attracts airborne pollutants and allergens as small as 0.3 microns. Thus, a series of purification processes can remove up to 99.97% of impurities present in the air. So, we can conclude on a positive note that air purifiers work great if they are bought wisely. 

Benefits of Using an Air Purifier

The benefits of having an air purifier are only realized by people who have allergies, respiratory problems, and pets in their homes. Regular people with no pet or health issues will only feel refreshed and healthier after breathing clean air provided by an air purifier, but people with health issues will find it as a lifesaver. Let’s have a close look at the benefits of using an air purifier. 

Fights asthma symptoms

According to a credible study, one in twelve people suffer from asthma in the United States. Asthma patients live with sensitive bronchial tubes. Fine airborne particles like pollen, dust, spores, pet dander, etc are very harmful to them as they cause difficulty in breathing by irritating the airways. Air purifiers effectively remove these pollutants and help relieve symptoms of asthma.

 Removes harmful chemicals

If you live in a roadside house or industrial area, it is highly possible that you are exposed to harmful chemicals like nitrogen dioxide and carbon monoxide. These gases increase the chances of getting affected with many chronic diseases.

Moreover, many household cleaners spread toxic chemicals like phthalates, chlorine, and ammonia. Continuous exposure to such chemicals can cause cancer, tumors, cardiovascular and neurological diseases. A quality air purifier can remove all these ultrafine particles with excellent efficiency.

Reduces unpleasant odors

We use aerosol sprays, air fresheners, body sprays, and have upholstered furniture in our home. All these things contain different VOCs namely benzene, gasoline, formaldehyde, etc, and contribute to making an unpleasant odor. Besides, there are other household odors caused by cooking, smoking, and pets. An air purifier can absorb all these smells and provide a clean and healthy environment for the dwellers.

Eliminates allergens that cause cold and flu

Viruses, bacteria, and different pathogens are present in the air inside our rooms. These airborne pollutants and allergens cause people to get cold and flu. If you are sensitive to allergens, this will make your life miserable in allergy seasons, especially, children and elderly people are more susceptible to these allergens due to their weak immune system. Air purifiers eliminate these allergens to help them fight these allergens. 

Improves sleep

You won’t get a sound sleep if you continuously sneeze and have a runny or congested nose, watery eyes, or sore throat. All these allergic symptoms are common in people who have allergy problems. Bacteria, viruses, dust mites, fungi, etc indoor allergens are responsible for these illnesses. Air purifiers ensure disruption-free nights of sleep by eliminating these allergens. Moreover, most of the purifiers have a night mode to help you get sound sleep while having a purifier switched on at night. 

Removes asbestos particles and radon gas

Different hardware and building materials contain harmful radon gas and asbestos particles. If your wall or roof has cracks and you use low-quality pipes and building materials, chances are high that you may have radon and asbestos particles in your room. Air purifiers can trap these hazardous particles too.  

Ensures healthy air for pets and pet owners

Pets with furs and feathers are prone to produce a good amount of pet dander and hair. Birds, cats, and dogs are the most common pets and all of these are likely to spread dander all over the house. If you have pets but don’t clean your room and furniture regularly, the environment will be unhealthy for both you and your pets. You can buy an air purifier that works best for pet dander to get rid of such problems. 

Things to Consider When Looking for an Air Purifier

The initial step to getting the best out of your purifier lies in making an educated buying decision. You must keep a few things in mind while buying an air purifier that is suitable for your needs and within your budget. You can go for an air purifier under $100 if you have a tight budget. Remember the following factors to make sure you’re not wasting money on a purifier.

Understand Your Needs

One may need air purifiers for different reasons. Some people only need to remove airborne particles and household odors whereas some others may need a medical-grade air purifier or a purifier dedicated to pet owners. So, at first, you must figure out why you need an air purifier. If you buy a purifier as per your needs, it will not be a waste of money for sure.  

Measure the Room

Each air purifier has a maximum coverage area. If you employ a low-capacity purifier for a large room, that will surely be a total waste of money. Measure the room size accurately beforehand and choose a purifier ideal for that particular size. Thus you will be able to make the best use of your money and the filtration will be on point too. 

Check for HEPA filters

HEPA filters have made revolutionary changes in air filtration technology. Always look for a true HEPA filter when making a purchase. At least, go for a HEPA grade filter if you don’t find a true HEPA filter. There are also other types of filters that are effective, but we recommend you look for HEPA filters for guaranteed performance.

Other Important Features

Noise Level

As a purifier runs in the background when you’re asleep, it is important to buy an air purifier that features a night mode option. Air purifiers producing less than 30 decibels sound at a lower speed setting are ideal for people who want disruption-free sleep. Though the level of noise depends on the speed settings. Don’t buy an air purifier that produces more than 55-60 decibels sound when operated at the highest speed. 

CADR Ratings

CADR rating refers to the cleaning ability of an air purifier for particular room sizes. A purifier with CADR 300 cubic feet per minute means that it has the capacity to clean the air of a 300 square feet sized room faster than purifiers having a CADR rating less than 300 cfm. You should choose purifiers with CADR ratings of 300-400 cfm for medium-sized rooms.


The more certificates an air purifier is affiliated with, the better product it is. Search for international certification organizations and awards like Safe Ozone, AHAM, Energy Star, Red Dot, CARB, ETL, G-Mark, Chicago Athenaeum, etc. Especially, the Energy Star label is very important as it means the unit is energy-efficient, consuming low energy. 

Low Maintenance

If your air purifier requires frequent filter replacement and maintenance, it will cost more money than a model that needs less maintenance. Look for a filter that doesn’t require frequent cleaning and filter replacement for at least 6 months. This will save both your time and money. 

Ozone Free

Low-quality filters tend to produce ozone gas which is harmful to both health and the environment. Long term exposure to ozone gas will cause respiratory diseases to the residents. So, look for a unit that is ozone-safe and does not produce a significant amount of ozone gas. 

How to Use a Purifier for the Best Outcome

Only buying a good quality product will do no good if you don’t know how to use it in the right ways. Check the following points. 

  1. Choose the perfect location to get optimal results. Keep it moderately near to the bed, couch, working desk so that you get the best quality air. 
  2. If your purifier circulates air at 360 degrees, you can place it anywhere but most of the purifier has air outlets on the front. So, keep your unit at a corner and keep the front side exposed to the available space. 
  3. Keep the room airtight by closing windows and doors. The filtered air will spread outside If you keep the doors and windows open.
  4. Check the filters after 2-3 months and clean them if needed. 
  5.  Keep an eye on the filter change indicator. Collect a replacement filter before the older one gets completely consumed.

On the basis of the above discussion, we can confidently say that air purifiers aren’t a waste of money. Yes, you need to choose the right filter for the right purpose. Only then it will be worthy of your investment. Wish you all the best on your purchase, and hopefully, you will make a well-informed decision to get the best out of your purifier.
