How Loud is the IQAir HealthPro Plus New Edition Air Purifier?

The IQAir HealthPro Plus is the quietest and most effective room air purifier on the market today. How is it able to so effectively clean the air while also being quieter than other air purifiers?

Here are three main reasons:


New Edition Red Label Fan

The New Edition Red Label Fan is the most powerful fan ever used in a residential room air purifier. State-of-the-art aerodynamic 7-blade fan design converts energy into more air and less noise with the highest quality fan motor available. The New Edition Red Label fan has an astonishing 780 cfm rating at 2750 rpm. Because each fan is individually balanced and uses steel ball bearings, it outlasts other fans by years. The IQAir New Edition fan is suspended in a housing unit that isolates the fan from the housing with eight shock absorbers to further reduce noise.


6 Progammable Fan Speeds

With most brands of True HEPA air purifiers, you get a choice of only 3 fan speeds, which means you can either have good air cleaning (and a lot of noise) on high speed, virtually no air cleaning (and low noise) on low speed, or some combination of the two on the middle speed. That one middle speed is really your only hope for a decent level of air cleaning, but if it's too noisy for you, you're out of luck. The IQAir HealthPro Plus has 6 speeds (twice as many as the competition), giving you plenty of flexibility and options. It is very quiet on the lower speeds 1, 2, and 3 (in fact, it's nearly silent on speed 1). We generally recommend running it on speed 2 or 3 for the most part, which provides a good level of cleaning at a very low sound level. You'll barely notice it's even running. Of course you can always turn it up to a higher speed when you need the occasional quick burst of clean air, or when combating a particularly high level of air pollution or odors. And if you are a light sleeper, simply set the programmable timer so that the HealthPro Plus runs on low speed at night while you are sleeping, and set it to automatically change to a higher speed for a couple of hours while you are not home.


Draft-Free 320° Air Exhaust

Most other air cleaners return all of its filtered air into the room through a single small, noisy and drafty outlet. The IQAir HealthPro Plus was designed with 320-degree air delivery to supply more air in more directions without drafts or noise. Other systems create annoying air drafts and restrict the ability of the system to produce fresh, clean air that can fill the room when you need it. The IQAir HealthPro Series boosts system efficiency by evenly returning cleaned air through a large 320-degree EvenFlow™ vented diffuser. And the wide dispersion pattern allows the HealthPro Plus to produce an astounding air delivery rate with very little noise.


That sounds great, but how loud is it really?

The HealthPro Plus New Edition is barely audible (near-silent) on low, comparable to the sound of rustling leaves, or literally a whisper. On speed 3 which is the most commonly used speed, it is about as quiet as a refrigerator or computer. Even on its highest speed 6 which is generally reserved only for occasional quick cleaning of large areas, the HealthPro Plus New Edition makes about as much noise as your dishwasher or shower.

Here are the decibel ratings for each fan speed and the corresponding level of noise each one sounds like:

Speed dB(A) Sounds Like
1 35 Whisper
2 46 Babbling Brook
3 54 Refrigerator
4 60 Conversational Speech
5 64 Conversational Speech
6 69 Dishwasher
