Improving indoor air quality is beneficial for anyone. Indoor air quality is under threat from wafted-in pollutants, allergens, dust particles, candles, open fires, Volatile Organic Compounds (VOCs) from cleaning products and “off-gassing”. They can be especially helpful if you are an allergy or asthma sufferer, an air purifier with a HEPA (High Efficiency Particulate Air) filter may be helpful for you as it will be good at removing fine airborne particles.
There are different types of filter and which do you need? The more stages of filtration, the better, to remove different sized particles.
- HEPA filter – this catches more dust, pollens, other allergens, even bacteria, so you’ll breathe cleaner whether you suffer from pet allergies or hay fever.
- Electrostatic filtration – this charge small particles so that they stick more easily to the filters.
- Active carbon – this is great for very small particles from traffic fumes, cigarette smoke and the Volatile Organic Compounds (VOCs) that carry unpleasant smells. They can even remove viruses from the air.
Finally, no matter which types of filters your air purifier uses, it’s important to replace them regularly. Most filters provide recommended replacement timelines based on how often you run your device. If your filter is dirty or has reached its capacity, your purifier won’t do much good.
