How to Choose Quiet Air Purifier 

Not all air purifiers are suitable for all pollutants and environments in terms of noise levels. Below are certain factors worth considering when choosing a quiet air purifier for your use. 

Decibel ratings 

Decibels (dB) are used to rate air purifiers’ noise levels. For example, the dB of air purifiers meant for bedrooms differs from those used in offices.

Pollutant types

Air purifiers with HEPA filters are suitable for allergies, smoke, mold, pollen, and dust, while activated carbon filters are well suited to odors and volatile organic compounds (VOCs). 

Fan speed ratings

Fan speed rating determines the efficiency of an air purifier especially filter-based air purifiers. The more the fan speed, the quicker the air purifier cleanses the air. 

Purification technologies

Some quiet air purifiers are made with permanent filters and are better for people with asthma, allergies, dusty areas, and pets. These air purifiers also have long-term economic benefits.

Room sizes

Using a larger air purifier for your room is better than using a smaller one. An ideal air purifier should have a CADR (clean air delivery rate) equal to 2/3 of the room’s area.

Why Whisper Air Purifier Is Essential for Some Conditions
