How to Choose the Best Air Purifier
- Consider your needs – if you have pets, you’d most likely want to get rid of foul odours, pet hairs and pet-related dust and particles in the air. Other people who live in a very humid area might be concerned about mould. There are cleaners designed to deal with mould mainly.
- Consider different filters – some filters can be washed and reused, others need to be replaced every 3-6 months, depending on the filter. This will affect your budget, and it requires a lot of maintenance. Make sure to consider this when choosing an air purifier.
- Consider the CADR (clean air delivery rate) rating, the speed at which it cleans air – this will determine how often you’d need to run your air purifier and how much you’ll pay for electricity. Some cleaners have a high CADR score, and you’ll only have to run it for a short amount of time, saving you electricity.
- How frequently would you use the cleaner? If you want the air to be clean only when there’s someone home, you’ll only have to run it a bit before you get home and until you leave again. Some purifiers have settings to turn on and off on a timer, perfect for that scenario.
- Consider the room size – some air purifiers don’t work well in large rooms.
- Consider maintenance level – if you don’t have enough time to maintain it, get one that only needs its filter replaced twice a year or so, otherwise get one whose filter can be reused, for example.
