Because of their recent rise in popularity, the market for air purifiers has been flooded with hundreds of models. Check out this detailed buyer’s guide for some tips and things to look for when searching for the right air purifier for your specific needs.
Air purifiers come in many different shapes and sizes, from smaller models that plug into the wall to larger versions that can clean the air in a whole house.
When choosing an air purifier, you should think about the rooms you want to clean the air in — or you can go for a portable unit that you can use all over your house. Once you have the measurements of your area, you can choose an air purifier that takes up the right amount of space.
Most high-quality air purifiers have three or five-stage filtration systems that can get rid of all kinds of air pollutants. We recommend getting an air purifier with at least a pre-filter, a HEPA filter, and a carbon filter for the right amount of air filtration.
The pre-filter gets rid of bigger, more obvious pollutants that can hurt the fine-filtration layers inside. The air then goes through a HEPA filter, which catches the smaller particles. Last, the carbon filter soaks up the gaseous molecules that can cause different smells to linger in a room.
ACH is the number of times in an hour that an air purifier can clean and change all of the air in a room. The higher this number is, the more efficient an air purifier is. Try to get an air purifier that can change the air at least four times an hour.
CADR is the amount of air that an air purifier can clean at its highest speed. The rate of cleaning the air is faster when the CADR is higher.
You should know that an air purifier can be a loud household appliance. While the noise won’t bother you much during the day, it can keep you from sleeping well at night.
So, if you want to use an air purifier at night, make sure to get one that doesn’t make a lot of noise. Look for a model that has a sleep mode or makes a noise at less than 40 decibels.
Here are a few tips to help you get the most out of your air purifier:
