How to Choose the Most Effective Air Purification System

August 12, 2020

Every home harbors some pollutants, but smoke and odors from cooking fumes, cigarettes and firewood are the most common. There are also microscopic airborne allergens such as dust mites, pet dander, bacteria, viruses, mildew, mold and pollen. These pollutants are health hazards that can cause allergic reactions, especially in people with respiratory conditions. To eliminate these allergens, you need to get a good air purification system. Here are some of the things you should keep in mind when shopping for one.

1. Consider What You Intend to Remove

Various air purification systems can remove different impurities from your home. However, effectiveness largely depends on the make and model. It would be best to note down the impurities you intend to eliminate inside your residence. This will aid you when shopping for an air purifier.

2. Decide How Efficient You Want the System to Be

With a wide variety of filter types on the market, the filtration efficiency of air purifiers might vary widely. If you have mild allergies or you’re only seeking significantly cleaner air to breathe, there are many acceptable choices within your budget. The efficiency provided by a HEPA-type purifier might be enough for your needs. However, if you have serious allergies or are sensitive to chemicals, you may wish to invest in something more effective. An air purifier with a HEPA filter can remove up to 99.97% of airborne particulates.

3. Determine the Size of Air Purifier You Need

To select the right size of purifier for your home needs, you must keep in mind the square footage of the space you would like to purify. Air purifiers come in different sizes and air change rates or ACH (air changes per hour). ASHRAE (formerly the American Society of Heating, Refrigerating and Air-Conditioning Engineers) recommends .35 air changes per hour. However, if you have a respiratory condition or allergies, you need an air purifier with a much higher capacity.


With so many air filter types and brands on the market, selecting an air purifier system might seem to be a daunting task. You can use the above points as a guide to help you find an air purifier that will best meet your needs.
