What is a Large Room Air Purifier and Why You Need One 

It’s all about the airborne particulates.

Different air purifiers will target different indoor air quality pollutants. It’s important when shopping for a large room air purifier that you find one that can pull out the pollutants that may be in your home. Then you’ll need to look at the coverage that the air purifier can provide to make sure you can effectively reduce pollutants in your large room.

The type of pollutant matters because each indoor air quality issue has a different size of particulate. If the filter can’t pull out that pollutant, then it will just get pushed back into the air that you breathe by the air purifier. You’ll have wasted your money. Here is a look at the size of some of today’s most common indoor air quality pollutants.

  • Mold: 1-5 microns, up to 20 microns for large colonies.
  • Bacteria: 0.3-3 microns.
  • Dust Mites: 10-40 microns.
  • Plant Spores: 10-70 microns.
  • Pet Dander: 0.3-5 microns.
  • Pollen: 10-100 microns.
  • Fungi: 0.5 – 5 microns.
  • Cigarette Smoke: 0.003-0.04 microns. 

As you can see, some basic air purification can help you eliminate dust mites, some mold spores, and many bothersome pollens. Upgrading to true HEPA filtration can help you to remove bacteria, small pet dander, and fungi contaminants. Cigarette smoke, however, can be difficult to remove for even the best large room air purifiers because this contaminant is so small. 

With the right air purifier, you can limit these pollutants very effectively. The best way to do that is to find a large room air purifier built with the features that can take care of your needs right now. 

The Features of a Large Room Air Purifier 

Every large room air purifier you look at today should focus on one thing: air circulation. This is the biggest struggle that a large room has. Because the space is so open and large, it can be very easy to have ineffective air circulation. Vaulted ceilings and other architectural features can enhance this problem. If the air purifier doesn’t promote air circulation, it will never truly filter the entire indoor environment.

Depending on the contaminants in the large room, you may also wish to shop for an air purifier that is built to be a sealed system. Sealed systems trap the particulates that are filtered out of the air and won’t let them leak back out if you forget to change a filter or the unit runs into a mechanical issue for some reason.

Odors can also be a problem for some large room air purifiers. Removing odors is a little different from removing particulate contaminants. You need to have a feature included with the air purifier that allows for carbon filtration of the air. If all you’re using is a HEPA filter, then the odors are going to pass right through and come back out once the purifier has cycled.

You’ll also want to look for a large room air purifier that is rated for 24/7 use. If it’s not running all day at a constant level, then there will always be pockets of air that get trapped in large rooms that will never be filtered.

Factors to Consider When Shopping for a Large Room Air Purifier

  • Coverage area. You’ll want to make sure that your large room air purifier can actually handle the room you plan to have it operate in. Most manufacturers use an 8 foot ceiling as a guideline for their square footage recommendations, so keep that in mind if your ceilings are higher.
  • ACH. This is the “air changes per hour” rating of the air purifier. The number is a reflection of how many times the air is filtered in the room per hour. A rating of 5 indicates 5 total air changes for each hour of operation.
  • Filter replacement. Even HEPA filters need to be replaced occasionally. Don’t forget to make sure you can access the filter and if replacement filters are available for your preferred air purifier.
  • Noise pollution. Some large room air purifiers are needlessly loud. If you don’t want your ears ringing when you’re in the same room as this machine, then look for whisper-quiet technologies as part of the shopping process.
  • Ozone creation. There are air purifiers that produce high levels of ozone. Some air purifiers only create ozone. It can be a lung irritant, especially for those with asthma issues, so look for models that keep ozone levels down. 

What Are the Prices of the Best Large Room Air Purifiers? 

These aren’t going to be cheap air purifiers. Large room models need to have high levels of output, strong motors and support mechanisms for continuous running, and high coverage ratings. This means you won’t typically find a good large room air purifier for less than $100. Premium models in this category can be over $700 if you need medical-grade components. For $150-$250, most households can find something that will meet their needs.
