Essential Facts You Should Know Before Buying an Air Purifier

An air purifier for your home

Air purifiers have become essential since the the start of the COVID-19 pandemic. It’s never been more important to keep indoor environments clean than now, and air purifiers have been very useful in this regard.

Before you spend money on an air purifier, however, make sure that you have the information necessary to choose the right one for your home. Shackelford Heating & Cooling, a trusted expert in heating and central air conditioning systems, shares some air purifier facts and tips below.

Air Purifiers: Basic Facts

Air purifiers are helpful in preserving indoor air quality. They sanitize the air by emitting ions or ozone, or by utilizing heat or UV or UVC lamps . They can also reduce odors and get rid of contaminants that could potentially make you sick or trigger allergies.

Air purifiers typically work hand-in-hand with air cleaners, which filter the air flowing inside your home. These air cleaners clean the air and collect dust and other larger particles including pet dander.


Airborne particles that find their way into your home are extremely tiny. Particles of dust, smoke and bacteria can measure around .3 microns or less. When picking out an air purifier for your home, look at its CADR rating, which refers to the efficiency and airflow rate of the device. It basically tells you how effectively an air purifier can filter out specific pollutants.

To determine if your air purifier will be able to provide optimal performance, you can consult an expert. It would be best to enlist central air conditioner maintenance services too.

Tips on Choosing an Air Purifier

Another thing that you should consider when buying an air purifier is the type of filter it uses. Experts recommend getting an air purifier with a HEPA filter, which is the gold standard for indoor air purifiers.

Look at the noise level and bonus features of the air purifier as well. Ideally, you’ll want something that operates quietly. If you prefer a device with app integration, feel free to opt for it.
