 Consider Before Buying The Best Air Purifier

Things to Consider Before Buying The Best Air Purifier

1. Main purpose

benefits of buying best air purifier

Allergies: If you are suffering from allergies, you can choose an air purifier that’s specifically designed for allergy relief.

Asthma: If you have asthma, you should choose a purifier that removes odor and other chemical pollutants.

Smoke:  Some air purifiers are specifically designed to filter smoke and fumes that can harm respiratory systems.

Pets: Go for a purifier that can remove animal dander, odor, or hair and keeps air clean and germ-free.

2. Size of Air Purifier

To choose an air purifier based on dimensions; consider the area of the room you want to purify. If you are suffering from breathlessness (asthma) and want a purifier to alleviate the symptoms, you should consider a purifier based on ACH (air change per hour) or the number of times the purifier filters the entire volume of air. 

actual Size of Air Purifier

For asthma or allergy patients, purifiers having an ACH rate equal to 4 is the best as it cleans by removing harmful allergens from the air.

  1. Small:  These purifiers are meant for rooms up to the 299-meter square
  2. Medium: These purifiers are meant for rooms up to 300 to 699-meter square

iii. Large: These purifiers are meant for rooms up to 700 to 1900 meter square.

3. Location of the Air Purifier

In most cases, you are advised to place the air purifier where you spend your maximum time.  You should keep in mind that light purifiers are meant to purify a single room only; it would be better to install additional units for other rooms.

air purifier where you spend your maximum time

In other words, go for a portable purifier that includes wheels and handles so that you can move it from one room to the other.

4. Air Purifier maintenance 

Purifier maintenance involves replacing the air filters.  The maintenance period varies depending on the technology used in developing air purifiers.

  1. Hepa (air) filters:  These filters last about 1 year depending on the usage.  Brands like IQAir HyperHEPA can last for about 4.5 to 5 years.
  2. ii) Carbon (air) filters: Carbon Filters lasts approx 6 months.

iii) Pre-filters: These filters last for about 3 months. Some washable fitters can last for a longer time span.

5. Desirable  Features of Air Purifier

After you have chosen the size and type of air purifier, consider some special features of the air purifier.

  • If you want to save both money and energy; go for purifiers that are rated by the EPA.
  • There are wifi air purifiers as well that you control from your smart-phones.
  • You can include features such as remote controls, portability, and filter change indicators

Types of Air Purifiers

1. Hepa Technology Air purifiers

HEPA stands for High-Efficiency Particulate Air. That means this is highly efficient in trapping microscopic (minute) particles like animal dander, dust, allergens, and other unwanted contaminants.

You should go for a product that is labeled as “Pure Hepa”. Such products must meet all the standards set by the US Department of Energy. The standards ensure that these filters are capable of capturing 99.97 % minute particles.

Hepa Technology Air purifiers

Details of Hepa Technology Air Purifier

Hepa Technology Air Purifiers are high-tech purifiers and are used by asthma doctors to reduce the symptoms of these diseases. 

Due to the quality performance of the air purifiers you need to change the filters often, as the small holes of the size of the filter sheet would increase the airflow cycle and filter life. The more rapid air flows through the filters, the cleaner the room becomes.  

However, these air purifiers will not clean your entire home; it’s better to have a purifier for all the rooms so that the entire home gets cleaned up.

2. Activated Carbon Technology

These are small pieces of carbon available in granular or powdered form.   A large surface area enables these carbon filters to absorb allergens than normal carbon. 

There are several advantages of using activated carbon.  These purifiers enable you to get rid of unwanted impurities and contaminants.  

Activated carbon can be used along with HEPA filters to trap impurities like dust, smoke, lint, and other chemicals

4. Ozone Air Purifier

Hepa or ionic purifiers use electrostatic plates as the means of filtration; they use ozone to remove unpleasant smell/odor. 

Ozone Generators:

These devices produce huge amounts of ozone as they don’t have any other means of filtration. Either they have a small pre-filter for dust or other contaminants or they can’t remove allergens and contaminants.  

Advantages of Ozone

Ozone is a molecule that can react and eliminate strong odors and chemical pollutants. Ozone smells like a crisp air freshener.   The ability to remove unpleasant odors makes it appealing to the customers/users as an air-purifying chemical.

5. UV Air Purifiers

According to doctors and health experts, air free of contaminants and allergens ensure long term health. We are fortunate enough to have an air purification system that deals with harmful microorganisms like virus, bacteria which were not there some years ago.  When the time comes for you to choose from purifiers that ensure clean and germ-free air, filters with UV air purification may be a perfect choice that meets your requirements. 

Basics of UV Air Purification

UV air filtrations use ultra-modern UV light technology to trap dust and other unwanted contaminants to keep bacteria from infecting office, home, and other indoor spaces.  UV Light destroys the genetic materials that prevent the microorganisms from reproducing and spreading diseases. UV air filtration system combines UV lamps with air filters to remove air pollutants and kill germs. 

These are the best UV air purifiers

  • SilverOnyx 5 speed KJ150F-C02
  • GermGuardian AC4825
  • Oransi Finn UV Air Purifiers

6.  Negative Ions

Air Ionizer makes the air clean and germ-air by charging the air molecules. Ions are used to remove allergens and contaminants. Ionizers make the air healthier for people suffering from breathlessness like asthma, allergy, and other respiratory diseases.

What are Ionizers? How do they work? 

The ionizer creates negative ions using electrical energy and releases them into the air. These negative ions get attached to positively charged substances like dust and other contaminants.  These positively charged particles and negatively charged ions combine to create dense particles that cannot float in the air; as a result, these dust particles fall off.
