Best Air Purifier Buying Guide And Considerations 

Before buying an air purifier, you should consider these important points. 

Type of Air Purifier 

There are two types of air purifiers: Whole-House Air Purifier and Room Air Purifier. The Room air purifier is smaller and more affordable than the Whole House Air Purifier. 

Before you settle with either one of them, you should know the answer to these questions. Where will the air purifier be used? Who will use the air purifier? 

Perhaps, houses that do not have a heating system need a room air purifier more than any type. 

Air Filtration Technology

Each air purifier does not use the same type of air filtration technology. The commonly used air filtration technology in many air purifiers is HEPA technology. 

It is the most preferred option for trapping radioactive molecules in the air. The surfaces of these filters are made specially to hoard air pollutants that are more than 0.3 microns. 

HEPA filters can be regarded as perfect but the downside of using them is that you have to replace them every 12 to 18 months. Other air filtration technologies include activated carbon filter technology and ULPA. 

Air Purifier Size

You will know the size of the air purifier to buy by the Clean Air Delivery Rate (CARD). The efficiency of an air purifier is determined by how high the mark is. The CADR for a particular room or space is gotten by multiplying its footage by 0.75.

Best Air Purifier Features

Every air purifier has a special function that is determined by its brand, size, and model. All purifiers need a fan to suck air into the device. However, the air purifiers without fans work poorly, compared to those with fans. 

One other important feature to take note of is the servicing indicator. It helps to remind you of the due time for replacing the main parts of the air purifier.

Why Ozone-Free Air Purifiers?

Many air purifiers available in the markets produce some quantities of ozone. Ozone has some bad effects on the health of people especially those who suffer from allergies or have asthma. 

Some products are labeled ‘safe’ to show that they produce ozone in small quantities. However, even minute quantities may be bad, especially for children and pets, if the air purifiers are left on every time.

High-Efficiency Particulate Arrestor (HEPA) air purifiers are fitted with a decent mesh filter that traps airborne particles like bacteria, dust mite debris, pollen, pet dander, and even tobacco smell. 

Usually, the mesh is made from smooth glass fiber that can capture all the organisms carried by air, no matter how tiny they are. 

This is why it is recommended by allergy and asthma experts. In fact, the best air purifier for asthma is definitely a HEPA air purifier. Because they remove airborne allergens, you feel relief when you breathe in the air and your health remains in good shape. HEPA air filters are totally safe for home use.

3). Filter Needs To Be Replaced In Time

The filter should be changed every 6 months. The quality of air in the environment and level of use determines how long a filter will last.

Colzer 1556 Air Purifier Review: The FAQ

Do air purifiers emit radiation? 

Air purifiers do not give off ozone if they purify the air with high-efficiency particulate air filters (HEPA filters). However, ionizing air purifiers that have electric charges produce ozone. The ozone can be produced at harmful levels. 

Ozone emission can lead to health problems. Air purifiers that function with filters do not produce any dangerous by-products and even maintain health. They rid the air of allergens and leave only fresh air. But air purifiers that produce ozone are bad choices and potential hazards. 

Can air purifiers cause illness? 

People who are ill or suffer from asthma or allergies find air purifiers to be a lifesaver. This is because they are proven to clear dust, smoke, allergens, and other pollutants that may cause disease, from the air. Basically, air purifiers should not cause any sickness. 

Should my HEPA air cleaner run continuously 24/7?

Yes. Air purifiers are meant to run continuously in order to fulfill their purpose. Some studies have shown that turning off the system will return indoor pollution levels to their pre-filtration stage.
