In our latest guide we have spent numerous hours researching and finding the best quiet air purifiers to review. I guarantee you only the most silent of air purifier will make it onto our list.
The advantages of using an air purifier are hard to overlook. Anyone caring about the purity of the air they breathe and the overall health of household members has considered purchasing such a device at one time or another. For people suffering from respiratory problems and allergies, a high-quality air purifier is a must-have.
Ideally, you should consider installing an air purifier in every room of your home. However, such an approach way too expensive for most of us. So people opt for purchasing just a single unit for the one room they spend the majority of their time in… the bedroom.
Buying A Quiet Air Purifier For Your Bedroom
Breathing fresh air while you sleep can do wonders for fighting insomnia and feeling fresh and rested in the morning. However, all of the above is useless if you can’t fall asleep due to the loud air purifier noise.
While researching the best purifier options, you are bound to come across such a parameter as the noise the appliance makes. Its intensity differs depending on the model and the fan settings.
When attempting to find the most silent air purifier for your bedroom, you should consider the following two factors.
1. Sleep Mode
Sleep mode is an excellent way to keep your air purifier working quietly all through the night. Usually, it involves just the press of a button. The air purifier automatically adjusts the fan to the lowest setting and dims or turns off all the lights on the unit (usually LED display, filter indicators, and the like).
Without a sleep mode, you have to adjust the fan manually. Typically such air purifiers often don’t have the option of switching the light off unfortunately – so watch out for this.
2. Noise Levels
If you are a light sleeper, each little decibel (dB) counts. What I mean is that you have to learn how many decibels are comfortable for you. Each fan setting on an air purifier produces a certain amount of noise. Usually, you can find this parameter in the manual or by reading the reviews.
To have an overall idea of the noise level a purifier produces, take a look at this table.
- 10 dBs – a pin dropping
- 20 dBs – leaves rustling
- 30 dBs – quiet library whispering
- 40 dBs – a computer working
- 50 dBs – refrigerator working/rain falling
- 60 dBs – people talking
- 70 dBs – shower working
Can you sleep when the leaves are rustling? Most likely. Can you fall asleep when people are talking? Probably not.
