4 Factors to Consider Before Buying an Air Purifier

Updated: Jun 1

The average Canadian spends more than 90 percent of their time indoors. Therefore, indoor air quality plays a vital role in improving your health and well-being. Air purification systems clean the air by removing pollutants and pathogens, thereby improving the quality of the air you breathe.

Here are four factors to consider before buying an air purifier.

1. Air change per hour (ACH) rate

An ACH rating refers to the number of times an air purifier can filter a room's entire volume of air within an hour. Air purifiers with an ACH rate of four or more are best for people trying to mitigate asthma and allergy symptoms.


2. Size

Stand-alone air purifiers are designed to filter the air in a single room. As a result, they won’t clean the air in your whole home. Large units can clean rooms up to 175 square metres. However, make sure you choose a model that’s designed for an area slightly larger than your actual room size.

You may also want to consider purchasing a whole-home purification system. These units are integrated into your home’s HVAC system to clean the air in your entire home at once.


3. Features

Air purifiers come with a variety of features, including:

  • Smartphone integration

  • Air quality and filter change indicators

  • Portability features such as caster wheels and handles

  • Remote controls

  • Multiple fan speeds

  • Special filters for people who have multiple chemical sensitivities (MCS)

Additionally, you can look for Energy Star-rated units for maximum efficiency.


4. Maintenance

Most air purifiers require regular maintenance. This usually involves replacing or cleaning the unit’s filters. HEPA filters generally last a whole year, while carbon filters last six months and pre-filters about three. Moreover, some air purifiers use heat or UV light to kill bacteria and other pathogens and don’t require any maintenance.
