Top 5 Best Quiet HEPA Air Purifiers

I have discovered the best quiet HEPA air purifiers to keep your home's air clean. These top rated and quiet air purifiers will clean your air of dust, pollen, pet dander, mold spores using high quality HEPA filters. All of these top selling air purifiers have at least one setting that is whisper quiet.

  1. RabbitAir Ultra Quiet HEPA Air Purifier (Top Pick)

  3. Levoit Core 300 HEPA Quiet Air Purifier

What Is A Quiet HEPA Air Purifier?

In my view, a quiet HEPA air purifier is a device that filters your home's interior air using a HEPA filter — and that has at least one setting that is quiet while in operation.

What Is HEPA?

The acronym HEPA stands for high efficiency particulate air and it is a national standard for air filters. According to ASME and the U.S. Department of Energy, a HEPA filter must be able to filter out 99.97% of particles that are 0.3 microns in size.

For comparison, a human hair is about 50 microns in size.

Originally, HEPA was a trademarked term, but now it is a public term for this filtering efficiency standard.

HEPA filters usually have multiple pleats which gives it an accordian shape.

This accordian shape greatly increases the surface area of the HEPA filter so it can catch more particles in the air.

What Is A Quiet?

For an air purifier to be classified as quiet, I think it should have at least one speed setting that is very quiet — in the range of about 25-decibels or less (a whisper measures 30 decibels).

A quiet air purifier shouldn't disrupt your sleep or interfere with a phone conversation. It's not going to be completely inaudible, but it should be a gentle hum in the background.

How Many Layers of Filtration?

These top rated quiet HEPA air filters that I have chosen all have numerous levels of filtration — anywhere from 2-3 filters and up to 6 levels of filtration.

And not all of the filtration levels are necessarily physical filters. There are air purifiers that have negative ion generators that will freshen and clean your air by injecting negative ions into your interior space.

Some air purifiers have UV lights that will kill microbes such as mold spores as it passes by the ultraviolet radiation. Here is my popular guide on the best rated UV air purifiers installed in your HVAC system that will kill mold, viruses, and remove odors throughout your entire home.

What Is A Prefilter?

Almost all of these air purifiers have prefilters. Prefilters will filter out larger particles from the air so that they don't get to the HEPA filter and clog it up.

Having a proper prefilter in your air purifier will seriously extend the life of the HEPA filter.

Also, some prefilters are completely reusable and washable so you can save some money there.  I recently wrote an article on washable furnace filters that will save you some HVAC maintenance costs.

What Is A Charcoal Filter?

Most of these quiet HEPA air purifiers also have charcoal or activated carbon filters.

Activated carbon is basically charcoal that has been processed in way that makes it extremely porous which gives it a large surface area. The very large surface area of the carbon captures odor molecules from the air.

These carbon filters can remove cooking smells, smoke, and other foul odors.

How To Control Your Quiet HEPA Air Purifier?

There is a wide variety of control options for these quiet HEPA air purifiers. Some of them come with remotes while others are only controlled through a knob or button.

One of my top products, the RabbitAir Minus2, can even be controlled through your phone app.

Also, many of these purifiers have certain programs such as auto mode which will automatically adjust the fan speed (or turn the purifier off) as it detects particulates in the air — the "set and forget" mode.

There are also economy modes that will turn the air purifier to off or low when the purifier has detected no particulates or pollution in the air.

My #1 Top Pick: RabbitAir Ultra Quiet HEPA Air Purifier

My top pick for the best super quiet HEPA air purifier goes to the RabbitAir Minus2. Here's why...

#1. WiFi Connected

This is one of the rare air purifiers that is WiFi connected which gives you massive functionality. You can control the Minus2 through your phone or tablet, or just use the remote. You can choose between various programs or make a custom daily schedule. You can also just set the purifier to auto mode and forget about it.

#2. Six Stages of Filtration

The RabbitAir Minus2 has not two or three filters, but it actually has 5 different filters and the 6th stage is a negative ion purifier. Also, the HEPA filter was designed so that it lasts significantly longer than the standard "true HEPA" filters that most purifiers are selling.

#3. Wall Mounted

The RabbitAir can be mounted vertically on the wall to save space, and it just looks way cooler. The whole mounting bracket system comes with the purchase.
