What to look for in air purifier filters

1. Filter Type

There are several types of air purifier filters, including HEPA (High Efficiency Particulate Air), activated carbon, and pre-filters. HEPA filters are highly efficient at removing small particles, while activated carbon filters are best for removing odours and gases.

2. Size Compatibility

The size of the filter should match the size of your air purifier. A mismatched filter will not work effectively and may even damage the device.

3. Filter Life

Different filters have different lifespans. Some may need to be replaced every few months, while others may last a year or more. Always check the manufacturer's recommendations.

4. Air Quality Concerns

Your specific air quality concerns should guide your choice of filter. For example, if you're concerned about allergens, a HEPA filter would be a good choice. If you're dealing with strong odours or smoke, an activated carbon filter might be better.
