While it is capable of removing 99.5% of the airborne particles as small as 0.1 microns in diameter and not as excellent as the H13 grade (which is up to 99.97%), the overall performance is enough for areas with mild air pollution or people who don't suffer allergies or asthma.
Not saying that H11 HEPA filters are lower in the upfront cost. Particularly with this model, the filters are removable to be cleaned of hair and buildup with ease.

How To Choose The Quietest HEPA Air Purifier?
Noise Level
The noise of air purifiers is emitted from the fans, which means the lower the fan speeds, the quieter the unit
The noise ranges of air purifiers are from 17 to 67 decibels (dB). Therein, standard air purifiers work at 36 decibels and an ideally quiet model is at 32 decibels. If you place the unit next to you while sleeping or working, a whispering air purifier at 20 decibels will be your best bet.
But noise is not the sole element when considering an air purifier, performance does matter, too. And, the fans play a huge role in the unit’s functionality. The more powerful the fans, the better the air purifying capability.
To neutralize between operation noise and performance, it is recommended choosing a model with a variety of speed options.
Low speed settings are for sleep, work, or energy-saving while the higher ones are for a shorter cleaning time or higher levels of air pollution.
CADR Rating
CADR stands for Clean Air Delivery Rate, which tells you the efficiency levels of an air purifier at eliminating certain pollutants from the indoor air. So, the higher the CADR rating, the more efficient the unit.
A good CADR rating should be equal to at least 2/3 of the space’s area. HEPA air purifiers commonly achieve the highest CADR rating.
Coverage
Each air purifier is specifically designed to work well in rooms within specific dimensions which are expressed in either cubic foot (cu. Ft.) or square inches (in2).
Picking the wrong model for your space could result in overworking or inefficient, which leads to many consequences like shortened lifespan, steep energy bills, and exposure to harmful airborne molecules.
Larger models generally provide more coverage area than smaller ones, but it’s still recommended checking the coverage area of your intended unit to be certain.
