Consequently, different people need to prioritize different features. If you’re a complete beginner, don’t worry. Here are the things you should be looking at when buying the best room air purifier:
Are you looking for a personal purifying fan or something for the entire family? Keep in mind that one is easy to carry around while the other isn’t. At the same time, the latter is usually larger and more powerful, while the former isn’t as effective. Usually, air purifier sizes are classified as:

- Large (between 300 and 500 square feet)
- Extra Large (above 500 square feet)
Specific Features for Allergies
Secondly, you need to see what type of features the purifier has. For example, if you have pollen allergies, can the purifier detect and filter out pollen specifically? Pollen is very small, so get one with a HEPA filter (as HEPA filters collect fine particles). Similarly, other specific features include:
- Multi-stage filtration (more than one filter)
- Smoke and odor removal
- Air quality checker
- Chemical filtration
- Pet dander filtration
Most people need air purifiers for overnight use. Consequently, energy efficiency is a very important feature or else, air purifiers become a very expensive purchase. To make sure your air purifier is energy-efficient, look at those approved by Energy Star. Almost all the air purifiers in this list have Energy Star certification.
Amount of Maintenance Needed
The thing with air filtration systems is that they need to be cleaned regularly. For example, pre-filters collect large dust particles, pet dander, fur, mold, and hair. These can collect over time and block the air purifier in-vent if not cleaned out frequently.
Luckily, HEPA filters and activated carbon filters don’t require regular cleaning. However, they do need washing and replacement (respectively) after certain intervals.

Simply place your air purifier where the air is easily circulated. It’s best to place air purifiers in the middle of the room. Moreover, placing them on the floor is usually more effective than placing them on a shelf. In essence, you need to stay away from:
