Factors In Buying The Best Silent Air Purifier

All the best quality air purifiers come with HEPA filters (High-Efficiency Particulate Air) as these are the most efficient filters in clearing the air of almost 99.97% of particles that are 0.3 microns.

Some air purifiers are also equipped with activated carbon filters that are proven to eliminate all odors and chemicals from the surrounding air.

They remove smoke from cigarettes, fumes from the fireplace, pet odors, or kitchen odors.

Pre-filters are extremely useful when you need to extend the time of your filters before you have to change them. They are also great for maintaining the air purifier’s functionality and efficiency. They trap the large particles before they reach the main filters.

You should change filters regularly every 6 or 8 months. 

CADR (Clean Air Delivery Rate)

It is always best to look into the CADR of any air purifier you are looking to buy. It is a measure of how fast an air purifier can clean a particular volume of air around you in the most effective manner. CADR also varies on different sizes and brands of air purifiers.

You can watch this video to learn more about the importance of CADR:

Noise Level

It is best to choose an air purifier that has adjustable speed controls. Make sure you look at the noise level at the lowest setting and the highest to understand what is the best noise level for your use.

Any quietest air purifier that will have a noise level less than 60 dB at the high setting is perfect for your use. Any noise level above 60dB is not the best choice for an air purifier because it will not be silent at all.


The maintenance cost varies from one air purifier to the other. Pre-filters air purifiers might not need any filter change up to 8 months, and others might need changing every 3-4 months. Some models have permanent air filters too but they might be a heavy investment in the pocket.
