The first thing you need to consider is the noise that comes from the air purifier you choose. You need to keep in mind that the air purifier will be used both during the day and at night.
So, to be on the safe side, you need an air purifier that can perform as needed even while you sleep. An air purifier does not have to make unbearable noise.
Choose an air purifier that provides adequate cleaning power for the size of your room. If you have a large room, you should buy a large air purifier.
The size of an air purifier is measured by the airflow rate. It determines the particles filtered and the speed of filtration.
When choosing an air purifier, we recommend an air purifier with a CADR rating that is more than two-thirds the size of your room.
For example, if your room is 100 square meters, it should have at least a 67 rating.
- Efficiency of air purifiers
Air purifiers operate at different intervals per hour. This is indicated by the air change per hour and varies from 2-6 ACH.
An ACH rate of 2 means that your air is purified every 30 minutes. An ACH of 4 means your air is purified every 10 minutes. An ACH rate of 6 means that purification occurs every 10 minutes.
So, when choosing an air purifier, consider the intervals at which you want to purify your air.
There are three types of air filters: carbon filters, HEPA filters, activated carbon filters, and washable filters.
HEPA filters remove common allergens from the air. These include dust, pollen, and pet dander. Carbon or activated charcoal filters, on the other hand, filter irritants such as cooking odors and smoke. Washable filters, on the other hand, do not need to be replaced. When they become saturated, all you have to do is wash them and reuse them. It's that simple, and you're good to go.
