White Bathroom Air Purifier on Floor in Bathroom

Bathrooms… They seem to never stay clean no matter how often and how deep you clean. A room that’s the most susceptible to bacteria, odor, and mold is practically screaming for an air cleaning solution. Is using a bathroom air purifier the way to go? In a word, yes. But there are important specs you need to look for and you must know how to operate one efficiently for it to benefit your bathroom at all.

Luckily, here at Home Air Guides, we are professionals in the space. We’ve researched and used more air purifiers than you can believe. Using our expertise and knowledge, we have all of the tips and tricks you need to use a bathroom air purifier correctly and show you some of our favorite ones, including one that we think is best.

How Does a Bathroom Air Purifier Work?

Air purifiers work by pulling in the surrounding air with a fan to be treated inside the machine before being pushed back out. Put most simply, they are designed to clean the air. Everyone knows a bathroom can never be clean enough. This is accomplished by circulating air through a series of filters designed to trap particles.

In addition to the filters, you should look out for the CADR rating, or Clean Air Delivery Rate. It measures how efficiently air purifiers remove pollutants from the air. CADR ratings reflect the air volume in cubic feet per minute (CFM) that the purifier cleans.

HEPA Filter

A HEPA filter, or high efficiency particulate air, is designed to remove dust, pollen, mold, bacteria, and airborne particles with a size of 0.3 microns. They are one of the best types of filters for removing a vast majority of contaminants from the air.

True HEPA filters are designated even further. Tue HEPA filters are the only filters that are certified to remove 99.7% of those particles down to 0.3 microns. 

Activated Carbon Filter

A carbon filter is the only one on this list specially designed to tackle VOCs (volatile organic compounds) in the air. The air is passed through a bed of activated carbon, which combats the VOCs released by common household products. They also can be used to remove odors from the air, like tobacco smoke and cooking smells.

Any effective air purifier will have these two types of filters working together.

Can You Put Air Purifier in Bathroom?

In short, yes, absolutely. And you should! Bathrooms harbor a lot of bacteria and odor, making them the perfect candidate for air cleaning.

Air purifiers work best in enclosed spaces, so smaller rooms with closed doors and windows will let the purifiers work their best. Of all smaller rooms, bathrooms specifically are easy to meet those requirements. 

No matter how much you clean your bathroom, there is always going to be something being used in there that keeps it from staying its most spic and span. A lot of us now know that flushing toilets put bacteria out into the air and circulate it through the room. While we know to keep our toothbrushes out of the open air, there are plenty of other surfaces and airflow that collect that bacteria. 

In bathrooms with baths or showers, there are trials and tribulations that come with keeping that extreme humidity at bay. If a room is not properly circulated, mold can build up easily from the excess moisture and eventually the mold spores will become airborne. Air purifiers will capture airborne mold spores and keep your breathing clean and healthy.

How to Use an Air Purifier

If you do choose to use an air purifier, there are few things you can do to maximize its effectiveness.

First and foremost you’ll want to make sure you have the correct machine for your room size. This is especially easy in smaller spaces like bathrooms. Manufacturers will indicate the square footage that their machines are designed for.

An air purifier is only as good as its filters. So, you need to keep them cleaned or replaced regularly. That time frame depends on the machine and manufacturer.

They will also only be able to fully clean the air in an enclosed space. That means you’ll want to keep the doors and windows closed in the room.

When it comes to placement, don’t block the air flow or try to stick the machine in a corner or behind furniture. Even better if you can, lift it off the ground and onto a tabletop or stand.

Bottom Line

Using a bathroom air purifier is a no-brainer. It’s the room of the home that’s most difficult to keep clean, used frequently and susceptible to air quality issues. Air purifiers in the bathroom help with common issues like bacteria, odor and mold. While there are plenty of options on the market, the VEVA 8000 air purifier is the best choice to combine high performance and an extremely reasonable price point. It can’t be beat!
