Why Do You Need an Air Purifier for a Bathroom?

bathroom odors

Most of us are content with exhaust fans and scented candles for our bathrooms. However, if your bathroom doesn’t have ventilation or smells particularly nasty quite often, then air purifiers are your best bet to counter the problem.

They’re the best permanent solution for smelly areas, however odor-absorbing stuff like DampRid can also be used to help with the issue in the meantime. DampRid is pretty popular for its affordable price and easy availability. We’ve covered everything you need to know about this product in our review.

But there’s a far more important reason why you can put an air purifier in a bathroom: mold and mildew. Because bathrooms get wet almost every time we use them and remain that way for long periods, there’s a good chance of mold developing and thriving in the area.

This doesn’t only destroy the walls and cabinets but also poses a health risk by reducing the air quality in your bathroom. To save yourself from allergies and asthma triggers, installing an air purifier with a True HEPA filter is essential.

The Best Bathroom Air Purifier Buying Guide

Every room has its own needs, so here’s what you should look for in a bathroom air purifier.


Pay close attention to the filters used in the air purifier. Are they up to the standards? Will they be enough for your bathroom? At the very least, it should have a true HEPA and a prefilter.

The true HEPA filter will work against bacteria and other pathogens, while the prefilter will trap dust and other larger particles. A prefilter also protects and elongates your primary filter’s lifespan.

Odor Removal

If odors are one of the reasons why you’re investing in an air purifier, then look for a carbon filter in the device. It acts as the primary odor removing component of an air purifier, absorbing smells and keeping them trapped within itself.

If possible, try finding out how dense the carbon filter is. The heavier and denser the carbon layers, the more effective it’ll be.


Air purifiers have come a long way since they were first invented, and advancements in technology have made them readily available for everyone. Hence, you should not be spending more than a hundred bucks on your air purifier, especially if it’s for a bathroom.

This is because bathroom air purifiers are built to cover smaller areas and don’t require smart features such as a remote control or a touch display. This reduces their cost to a great extent.


Size is one of the most important aspects of a bathroom air purifier. You can’t fit in a large device in most bathrooms, especially smaller ones where space is tight.

Hence, an air purifier should be compact and short in height, taking as little space as possible. This will allow you to keep it on top of cabinets or at the corner of the floor, well away from water and chemicals.

CADR Rating

The Clean Air Delivery Rate (CADR) is a measurement of an air purifier’s effectiveness in removing pollutants such as smoke, dust, and pollen. For example, an air purifier with a CADR rating of 100 for smoke means that it is capable of removing smoke from the air at a rate of 100 cubic feet per minute.

Look for an air purifier with a high CADR rating to ensure effective air cleaning.


You’ll likely have to run your bathroom air purifier overnight, and when that’s the case, the unit needs to run quietly.

So always look for a quiet mode on your device, or a noise level between 25 to 50 dB, so you can sleep undisturbed.
