When buying an air purifier, it’s important to look for certain features to ensure it serves your needs and does it’s job well.
There are different purifiers for different room sizes, so before selecting one, make sure you know the size of the space you want to purify, or it may not be effective. To get truly purified air, look for HEPA filters, and avoid purifiers that claim to have “HEPA like” filters. If you intend to use the purifier in your bedroom while sleeping, look for a purifier that is effective even when set to a lower setting, so that you can minimize the noise it generates. Some air purifiers generate ozone gas during the filtration process, this can be damaging to your respiratory system, so make sure your choice doesn’t emit ozone gas. You will also need to factor in the maintenance cost of each replacement filter and consider how frequently you will need to replace them. While HEPA air cleaners are energy-efficient, the filters should be changed once every three months if they are used daily.
