Do air purifiers get rid of smells?

A common question for anyone researching air purifiers is ‘do they remove smells?’ – this all depends on the purifier being used and it’s features. Also most models of air purifiers will help with odor removal or tackling smells some are better equipped than others!

Although air purifiers are a great tool in the process of odor removal, there are other factors which need to be consider and actions you can take in your home to limit the impact of unpleasant smells.

It is important to understand what features to look for choosing an air purifier for odor elimination.

The best air purifiers for odor control are those fitted with activated carbon filters as these will work to adsorb smells within the home and remove pollutants from the air.

Purifiers without carbon filters will also remove smells from a home but may be less effective. Purifiers work by removing particles from the air down to 0.3 microns in size (A micron is 1/1,000,000 of a meter). Often these particles are those creating smells so when they are sucked up purifiers and removed from a rooms air they also remove the unwanted odors.


How do air purifiers remove odors and smells

As air purifiers are so quiet, unobtrusive and sleek in design with no visible moving parts it can be difficult to understand or appreciate what is happen with the unit.

Air purifiers are fans which pull air from a room into the device. The speed at which the air is brought into the purification device will depend on fan speed and CADR of the unit.

Once the air enters the device, it is passed through filters to help remove pollutants, odors, VOCs (volatile organic compound) and particles like dust, hair and pet fur.
All of these pollutants are trapped within the devices, true HEPA filter or carbon pre-filter.

Now that offending pollutants and particles have been removed from the air, the new air which is pushed out of the purifier is clean, fresh and much easier to breathe in.

An air purifier can completely cycle or change the air within a room at an incredible rate, ensuring a room is frequently refreshed with new air regularly.

This change rate is known as CADR and the higher the CADR number the better!

Another key tool in the air purifiers arsenal in the tackle against odors is an activated charcoal filter.

Carbon filters work be adsorbing particles which are causing odors. These particles are trapped on the carbon filter as the carbon is an incredibly porous and adsorbent material which has the ability to trap odors and airborne chemicals present effectively.

So, to recap true HEPA filters will capture tiny particles which are releasing doors and purifiers using activated carbon filter will trap particles on the surface of the carbon filter and thus remove the smells from the air of a room.
