Shopping for air purifiers and air cleaners in Canada? Staples is here to help. The major difference between air purifiers and air cleaners is that air cleaners are built to filter the air, while air purifiers can also sanitize the air by emitting negative ions and ozone control and may utilize heat in the process by using UV or UVC lamps. By doing so, air purifiers will remove contaminants from the air and zap impurities with Ultraviolet germicidal lamps. For some, this may be the preferred choice as air purifiers can create cleaner, healthier air –– which may be especially important for those living in busy industrial cities or landscapes. How to Choose the Best Air Purifier or Cleaner for Your Home If you’re less worried about pollutants and contaminants an air cleaner can be a great option as air cleaners will filter the air to collect dust, pollen, and pet dander, but many systems do so by using a fan that may contribute to more internal noise pollution than the standard purifier. That said, air cleaners can often filter larger spaces than the standard air purifier (which will often only be effective in one room at a time) and remove dust and dander that would go unnoticed by most air purifiers. To ensure you’re finding the right air cleaner, pay attention to the clean air delivery rate number or number of exchanges by hour. When shopping for an air purifier, look for the device’s air change per hour rate (ACH). This number refers to the number of times an air purifier can filter the entire volume of air (square footage may differ from product to product) in one space per hour.
