How We Chose the Best Air Purifier for PC Room Dust
To choose the best air purifier for pc room dust, we compared pre-filter, HEPA filter, room-size rating and owner feedback.
To learn how portable air cleaners and HEPA filters work, read the EPA guide to air cleaners and air filters in the home.
Product details in this guide are based on manufacturer specifications and verified owner feedback, not in-house lab testing. Read more on our How We Test page.
Buying Guide: How to Choose the Best Air Purifier for PC Room Dust
Keep these factors in mind when shopping for the best air purifier for pc room dust.
How to size an air purifier
Match the purifier to your room. Look for a True HEPA filter and a clean air delivery rate (CADR) or room-size rating at least as large as your room. Gaming rooms with carpets, pets or a PC pulling in dust benefit from running the purifier on low all day.
Why gaming rooms get hot
A gaming PC and monitor can put out several hundred watts of heat under load, which adds up in a small room with the door shut. Moving air across the room or out of it matters as much as cooling it.
How quiet is quiet?
Around 25 to 35 dB is a whisper and will not bother you in a headset or during sleep. Fans, purifiers and fridges get louder on high settings, so check the noise level for the speed you will actually use.
Ideal humidity for a gaming room
The EPA suggests keeping indoor humidity below 60%, ideally between 30% and 50%. Too dry and your eyes and throat feel scratchy; too damp and you risk mold and musty smells. A cheap hygrometer tells you which device you need.
Air purifier tips
Get cleaner air:
- Run the purifier on low all day instead of on high for an hour.
- Keep it a foot or two away from walls and furniture.
- Close the door so it only has one room to clean.
- Clean or replace the filters on the schedule in the manual.
