Bedroom air purifier considerations

Noise levels – quiet or white noise
Make sure you select a purifier which is quiet when running at various fan speeds and has a dedicated sleep or night mode. If desirable, look for a purifier which has a white noise or pink noise feature. As this can greatly improve the quality of sleep, you will experience at night.

Sleep mode features
Find a purifier which has a specific night or sleep mode and relevant sleep features like white noise creation, night light, dimmed controls when being used at night or auto light level detection.
If one of the key reasons for buying a purifier is to use it at night, then make sure it is specifically tailored to this use and up to the job!

Night light
Not all purifiers feature lights or night lights, so if this is a feature you are looking for make sure the purifiers you are researching have this feature.
Some purifiers designed for kids and babies even have light shows or changing night light colours which can be very relaxing when trying to get to sleep.

White / pink noise – sound generator
If you think ambient background noise will help you sleep, then look out for a purifier which has a white or pink noise function. This tends to trigger when purifiers are set to night or sleep mode.
Even if a purifier doesn’t have a specific noise creating feature, the low fan speed setting can provide a soothing sound at night.

This may not be a factor for everyone but once you buy a purifier for use in the bedroom, you may love it so much that you want to use it in other areas of the home. So make sure you choose a purifier which is portable – if this is a desired need.

Ideally a purifier should be placed well away from any walls to allow for sufficient ventilation and above the floor level to enable the purifier to capture dust in the air not just ground level.

Often it makes sense to place a purifier in the bedroom on a bedside table as this will mean the purifier is off the ground and has enough clearance from walls.
