Best Bedroom Air Purifier Review Guide

If you’re having trouble sleeping it could be down to the air quality in your bedroom.

Unseen to the naked eye there are tons of microscopic pollutants drifting through the air, including dust mites, pet dander, mold spores, and even viruses.

All of these pollutants can be detrimental to our health, especially those who suffer from allergies or any respiratory problems.

The good news is there are steps you can take to improve the air you breathe inside your bedroom. One of which is investing in a good air purifier.

According to the National Association of Home Builders the average bedroom measures between 309 and 481 square feet. What this means is that you don’t need a super-powerful, nor expensive air purifier to effectively clean the air in your bedroom.

In many cases, a compact model that’s inexpensive and good at what it does can do just fine. That being said, you don’t want to sell yourself short when purchasing an air purifier. At the end of the day, it’s your health you’re improving and how can you put a price on that?

So, before you rush out and buy the first model that you come to, take a few moments to consider what it is you actually need from an air purifier.

Here are a few things to bear in mind:

  • Noise level –  Having an air purifier in the bedroom is great in terms of all the clean air you get to breathe as you snooze. However, some models can be pretty noisy. And, unless you’re someone who’s an extremely deep sleeper and hears nothing in their sleep, this needs to be a top consideration. Most air purifiers operate at a noise level that’s somewhere between 21 decibels and 70 decibels.  The good news is that a majority of high efficiency air purifiers available do have a variety of fan speeds to choose from which will affect the noise output and so can be adjusted to a level to suit. This means you should ideally you invest in one that’s noise level can be set low enough to not disrupt your sleeping.
  • Room size – You need to get the dimensions of your bedroom to ensure you buy the most efficient air purifier you can. Buying one that’s too powerful for the room you’re in, will clean the air just fine, but is a waste of money. On the flip side, buying an air purifier that’s too small for the bedroom it’s going in will have minimal effect on the improving of the air you breathe. Many of the brands that produce purifiers measure in cubic feet coverage and that is likely to be a metric you see mentioned. In this guide we focus on air purifiers specifically aimed at bedrooms but some of the devices reviewed can also be used as a portable air purifier and just as easily used in a living room as your bedroom.
  • Space –  Another consideration to think about is where you’re going to place the air purifier. You need to make sure it has enough room to operate properly, yet you don’t really want to place it somewhere it will become a trip hazard. Some models are wall mountable too. So, if you are lacking in floor space, one of these models might be better for you.

These are the main considerations to think about before you make your final choice. Another factor to consider is if you have pets, you may want to get one that’s aimed specifically at tackling pet dander and pet hair. Or, if you suffer from any kind of breathing problem, such as asthma, you may want to opt for the one that cleans air the fastest.

Either way, the following list contains both. Keep reading to see which model will best suit your needs.
