Whether you’re awake or asleep, the quality of the air you breathe will impact how you feel. It’s for this reason that running your air purifier at night is just as valuable as during the day. In fact, some will buy an air purifier for the sole purpose of nightly use. This is because our allergies can become more of a nuisance as we sleep — waking us up with itchy throats or blocked noses. With disturbed sleep, this can impact how we feel the following day as well.
Air purifiers are often placed in a corner of the bedroom to run quietly at night while we sleep. You’ll find many models will come with a night mode for this exact purpose. When activated, this setting will lower the fan speed and reduce the noise output, so you can sleep through its operation while still reaping the benefits of clean air. Any lights on the control panel will often dim to help you sleep soundly as well.
Just remember, using an air purifier through the night will require more energy consumption, so this will increase the running costs. Make sure you opt for an Energy Star certified model to keep your bills at a minimum. If your air purifier is working hard at night to clean your air, avoid leaving windows and doors open as well — otherwise, this is counterproductive. Alternate between the two, and only open windows when the pollution levels are low.
