Filters: 3 things to consider before buying

Before purchasing filters, it's essential to determine what you need them for. Are you looking to improve air quality due to allergies, or do you simply want to maintain a fresh environment? Consider the specific pollutants you wish to target, such as dust, pollen, or smoke. This will help you choose the right type of filters with the appropriate efficiency rating.

Ensure that the filters you select are compatible with your existing air treatment system. Measure the dimensions accurately, noting both width and height in inches, as well as thickness. Many systems require specific sizes or types of filters, so double-check your model's requirements to avoid purchasing an incorrect size.

When selecting filters, think about how often they need replacing and the ease of doing so. Some filters are washable and reusable, while others require regular replacement every few months. Assess your willingness to perform maintenance and factor in the cost of replacements over time. This consideration ensures long-term satisfaction and effective air treatment.
