Select a portable air cleaner with an activated carbon filter or another gas-filtering filter. As far as gas-removing portable air cleaners or filters are concerned, there is no commonly accepted performance rating system. Only particles are rated with the CADR system. If a considerable amount of material is utilized in the filter, activated carbon filters can be effective. With a portable air cleaner equipped with an activated carbon filter, particles and gases can be filtered. In this post, we will give you a guide to choosing a portable air purifier.

Type of removal/air cleaning technology

There are four primary types of air-cleaning technology to choose from:

a. mechanical filtering

b. electrostatic air cleaners

c. ion generators

d. hybrid systems

The goal of each system is primarily the same: clean the air by reducing particles caused by pollution, interior fumes, smoking, dust, pollens, allergens and air-borne irritants.

Type of filter

One of the biggest differences between the purifiers is the type of filter that is used. You will want to be aware of the three types.

HEPA (High-Efficiency Particulate Air):

This filter removes high amounts of dust, as well as animal dander, pollen and dust mites. True HEPA is certified as 99.97% efficient, so look for a model with True HEPA certification. It is important to note that most HEPA filters must be changed annually. Be sure to check on the cost of replacement, or choose a model that can be cleaned and reused

ULPA (Ultra Low Penetration Air, or Ultra HEPA Filter):

This filter removes 99.97% of dust, pollen, mold, bacteria and airborne particles and is best for removing even the smallest particulates

CHARCOAL OR CARBON:

Charcoal or carbon filters work to remove larger particles such as those from smoke and odors. These types of filters are often featured as a pre-filter combined with HEPA or ULPA.

Air change/Efficiency rate (ACH)

The ACH rate, or Air Change per Hour, indicates how many times the air purifier will clean the room's air during the course of one hour. For example, 2 ACH means the air will be cleaned every 30 minutes, while 4 ACH means it will be cleaned every 15 minutes. The highest ACH rate is 6; or six complete cleanses per hour.

Clean Air Delivery Rate (CADR)

Now, while the ACH measures how frequently the air will be cleaned, the CADR, or Clean Air Delivery Rate, indicates the volume and speed at which particles will be filtered. Consider purchasing a purifier with a CADR rating that is at least equal to two-thirds of the room size (i.e., a 120-square-foot room would require a cleaner with a minimum of 80 CADR rating).

Room Size

While CADR gives you a good rating to work with, it is often advisable to select a model that is meant to work in an area slightly larger than the actual room size you will be placing the air purifier.
