Air purifiers come in different variants, so you might be asking, “what size air purifier do I need?”. We’re hoping to answer your question in this article, as we list down some fast facts on how to look for the just-right air purifier for your needs, as well as suggestions.
Not all air purifiers will work for all room sizes and that’s why they have a specified coverage area (in square feet). By knowing this room rating, you will have an effective air purifier at hand that isn’t too overkill or too weak for your room size.
When choosing an air purifier, one of the most crucial points is to know if the air purifier’s rated size is just right for your room.
Can an air purifier be too big for a room?
A large air purifier will work in a small room but it still depends on its rated coverage area. We think it’s best to just use an air purifier that’s just right for the room and leave the bigger air purifier to do the job in larger rooms instead.
With that said, we handpicked some air purifiers you might want to check out depending on your room size. After all, Amazon’s air purifiers are among the best since they have good shipping, handling, and warranty policies – your unit will be in utmost care when it arrives at your doorstep.
1. Small Rooms: Germ Guardian AC4300BPTCA Air Purifier
For small spaces – at around 153 square feet, this air purifier will do the trick. It has a 5-filter system, which includes a pre-filter, a charcoal filter, a true HEPA filter, UV-C light, and an antimicrobial agent.
You can choose from 3 different speeds depending on your needs plus you can turn off the UV-C light when not needed. There’s also a filter change indicator to eliminate guesswork when performing maintenance on the unit. We also like how it has a slim design that will fit most small spaces.
2. Medium-Sized Rooms: LEVOIT Vital 100 Air Purifier for Home
If you want the best air purifier for homes that are sized up to 300 square feet, this air purifier is a decent choice. It also has activated carbon to target bad smells while the H13 true HEPA filter is a medical-grade one that will get rid of even the smallest airborne particles as much as 0.3 microns.
Due to the built-in handle, easily transporting it from one room to another is a breeze. This would be useful if you have multiple rooms that need air purifying. It also has a noise level of 23 dB on the lowest setting to help you sleep soundly. You can also turn off the LED screen to avoid getting distracted while you rest.
3. Large Rooms: MOOKA True HEPA+ Air Purifier
Are you looking for an air purifier for a large space? This one might be for you – it is ideal for rooms that are 540 square feet in size. This air purifier features 6 filtering steps, which include a pre-filter, true HEPA, activated carbon, VOC absorber, UV sterilizer, and negative ionizer.

4. Extra Large Rooms: Bissell air220 2609A Smart Purifier
This air purifier is good for rooms up to 800 square feet, allowing you to clean up the dust from really big areas around the house. It has a 3-stage filtration system, which includes an activated carbon filter, a HEPA filter, and a fabric pre-filter. The Automated CirQulate System is helpful so you don’t have to work with the settings since it already determines the best fan speed depending on the air pollution levels.
What we like in this unit is the discreet cord wrap, which makes it pleasing to the eyes and less of a hazard for pets and family members. Because accessing the filter is easy using the front panel, you can place it on the wall and maintain the filter as necessary without having to move the unit.
Do air purifiers use a lot of electricity?
No, air purifiers are low in consumption as compared to standard home appliances. Most will have 80 to 200 watts depending on the brand and its coverage area (as mentioned above). Bigger air purifiers that are meant for larger rooms will surely use more electricity, but it’s the same concept as buying an air conditioner that’s rated for large rooms, anyway.
How do you size an air purifier?
Knowing the rated size of an air purifier depends on these factors:
| CADR or clean air delivery rate | Different pollution concerns have different CADR for an air purifier. CADR measurements vary and are measured under the AHAM (Association of Home Appliance Manufacturers) standards. It is how airflow is measured on an air purifier or a similar device.
For example, the: Germ Guardian AC4300BPTCA Air Purifier has the following CADR:
|
| Room size | This is measured in square feet and is often indicated in the air purifier itself. It will also tell you a different room size rating depending on how long you keep the air purifier on. |
Is an air purifier worth buying?
Yes, an air purifier is worth buying, especially in today’s time when we need air sanitation the most. These home appliances might look expensive but in the long run, they will save your lungs from excessive coughing and sneezing that will result in irritation or some other health problem.
Conclusion
In the long run, it’s better to choose an air purifier that’s just right for your room size. When you pick a unit that’s overkill, you might end up paying more for your electric bill. On the other hand, if it’s too weak for your room, you’d have to abuse the highest speed, which will also cost electricity, can strain the motor, and also cause noise. By choosing an appropriately-sized air purifier, you’re saving bucks and time.
