Best Air Purifiers for Dust of 2020

You deserve cleaner air — your lungs will thank you.

It can sometimes feel like no matter how much you clean, there’s still dust in the air. This can irritate your eyes, throat, and even trigger allergies. Dust isn’t always visible and, therefore, is tricky to deal with.

Using the best air purifiers for dust can make a significant difference inside your house. But how can you find a suitable unit? There’s a range of air purifiers available on the market in different sizes and price ranges.

Why You Need an Air Purifier for Dust

“A little bit of dust never hurt anyone” is probably a phrase we’ve all used once in a while. However, the truth is that dust can actually harm you and your family members.

There are various sources of dust — the most common being the erosion of sand and soil. However, particles such as pollen and dander are also considered dust.

Human-made dust, though, is what can cause the most trouble. This is usually due to different activities such as gardening and various industrial ventures.

Dust exposure can have varying effects depending on our personal health. But often, people with allergies or asthma will have more severe reactions.

Common dust-related issues include:

  • Coughing.
  • Asthma attacks.
  • Eye irritation.
  • Sneezing.
  • Hayfever.

If you have young children or infants, getting an air purifier can help to reduce the risks of them inhaling dust (1).

What Makes the Best Air Purifiers for Dust?

Air purifiers are manufactured with various purposes in mind. For instance, some are best at removing allergens. Others, on the other hand, focus more on pet dander (skin sheds of pets, rodents, and birds).

You will find that the majority mention good effectiveness in most areas. However, there are still a few things to look for when your issues are specifically dust and dust mites.

1. Filter Stages

Dust particles come in different sizes and can vary from large and visible, to tiny and invisible. However, dust can cause quite a lot of trouble whether you’re dealing with allergies or not.

A good place to start is by considering the number of filtration stages the unit utilizes. Effective air purifiers for dust will have a pre-filter that catches large particles and a true HEPA filter that catches tiny particles.

2. True HEPA Filter

True HEPA filters are one of the most effective filters on the market. They can be found in vacuum cleaners, cars, and air purifiers.

There are a few variants of HEPA filters. They include HEPA-type and HEPA-grade. It’s essential to distinguish between these since they aren’t as effective as a true HEPA.

True HEPA filters will catch up to 99.97 percent of all particles as tiny as 0.3 microns. HEPA-type filters, though, will only capture up to 99 percent at the size of 2 microns. This means that they will still do well with dust, but small particles might escape (2).

3. Consider an Ionizer

Some air purifiers are fitted with an ionizer fan. These use ions to purify the air. It creates negative ions that attach to positive ions (dust, bacteria, smoke). When negative and positive ions bond, they become heavy and fall to the ground (3).

Take Note

This does require more frequent cleaning, so avoid this feature if you’re not up for that. Also, if you have severe allergies or asthma, an ionizer is not the right choice. Instead, opt for a strong air purifier to remove all of the dust particles.

The Best Air Purifiers for Dust of 2020

If you’re having trouble keeping dust at bay, an air purifier will help. We’ve sought out the best true HEPA filters and pre-filters that would eliminate as much dust as possible. After our expert team researched products and customer feedback, we created our list of the best air purifiers for dust.

1. Whirlpool Whispure True HEPA Air Purifier

Best High-End Purifier for Dust

Check Price

Our all-time favorite air purifier for dust is the Whirlpool Whispure. The sleek look combined with the True HEPA filter makes this a hard one to beat.

It might be a compact device, but it can cover large rooms and areas. There are four fan speeds to choose between. You can also choose to set it to auto mode and it will adjust the fan speed to the room.

You might be worried about how loud the Whispure is but think again. It’s surprisingly quiet and can be used during the night when you’re sound asleep.

Why We Love It

High-Quality Filters

For this air purifier to be as effective as it is, Whirlpool has equipped it with an active carbon filter and a true HEPA filter. The carbon filter removes odors such as smoke, cooking and pet smells. Then, the HEPA filter removes up to 99.97 percent of allergens such as dust.

A true HEPA filter removes particles as tiny as 0.3 microns. This includes pollen, mold spores and pet dander. So you and your family get to enjoy much cleaner air.

Auto Mode

You get four fan speeds to play around with. These include low, medium, high and turbo. The low and medium speeds are quiet enough to use at night while you’re sleeping.

When you’re unsure of the air quality, activate the auto mode. Here, the Whispure will monitor the air and adjust to it. The LED light will change color to indicate its current speed.

Good for Large Rooms

Despite being no taller than 25 inches, this air purifier will clean the air of a room up to the size of 508 square feet. Its CADR (Clean Air Delivery Rate) is at a sturdy 328, which means it’s both fast and powerful when it comes to removing dust.

Programmable Timer

One of the smarter features of the Whispure is the programmable timer. This enables you to set the purifier to start automatically whenever needed.

Keep In Mind

Replacement Filters Are Expensive

Overall, we are more than happy with this unit. However, when a replacement is needed, it falls flat. Replacement filters are not only expensive but can be difficult to get your hands on depending on where in the country (or world) you are.

You can effectively clear your living space of VOCs, dust, dust mites, mold and even viruses. If you have pets and are slightly bothered by certain odors such as cat litter, this unit will remove all odors.

The compact device can clean the air of a small to a large-sized room. It should change and replace your air two times per hour. Its prominent features include an air sensor and auto mode. It can even be controlled using a remote.

Why We Love It

Highly Effective

Although this unit isn’t as grand as other air purifiers, it’s still effective and of high quality. The four-stage filtration system includes a nano catalyst filter that removes larger dust particles and chemicals. To remove odors such as smoke and gases, the unit is fitted with an activated charcoal filter.

An anti bacterial filter removes and destroys bacteria, viruses and fungi such as mold. If you’re dealing with allergies, however, the true HEPA filter is the most crucial part. This effectively removes up to 99.97 percent of airborne particles, including pollen, fine dust and mites.

Air Quality Sensor

Most of us might think our indoor air quality is less polluted than outdoors, but this isn’t always the case. This unit will let you know just how polluted or clean your air is. It will monitor the quality and alert you via the changing LED lights.

When in auto mode, the air purifier will adapt the speed of the fan to suit the air quality. This gives you optimal results without having to guess or use more energy unnecessarily.

Super Quiet

If you enjoy purer air while sleeping and appreciate a silent room, this is for you. When in sleep mode, the unit will generate a mere 18 decibels — virtually silent.

Keep In Mind

Vague Instructions

Although this air purifier is top-notch, its instruction manual could do with a few more details. The manual tells you how to set the unit up and how to identify the various parts. But, it won’t tell you the reason behind different light signals that might indicate trouble or filter replacement.

True HEPA Filter

For the best dust and mites trap, you need a true HEPA filter. This one will trap dust particles as small as 0.3 microns. A honeycomb filter will take care of any large particles while the activated charcoal filter will remove odors.

Keep In Mind

The Filter Doesn’t Last for Long

Unfortunately, the filter on this smart unit won’t last for long. Most customers received a replacement notification only after two months of use.

360-Degree Air Consumption

To be even more efficient, the purifier draws air in from every side — it leaves no pollutants free to wreak havoc. You can place it in a large living space of up to 540 square feet for effective results.

Energy Star Certified

Some air purifiers tend to use an immense amount of energy which reflects on your energy bills. However, this unit uses only 60 watts — and that’s on the highest fan speed.


No matter where or when you want pure air, this can be used without causing a headache. The Blue Pure 211+ is fitted with a special polypropylene filter. This filter is finer and, therefore, doesn’t use as much force to clean the air.

On the lowest speed, the Blue Pure 211+ generates 31 decibels — about as loud as a whisper. When using the highest setting, it produces 56 decibels, which is similar to white noise.

Effective Filters

The advanced Swedish-designed filter captures up to 99 percent of airborne pollutants such as bacteria, dust and viruses. Unpleasant odors such as smoke and pet smells are absorbed by the active carbon filter.

You can expect fast results, even in large rooms. The unit has been independently tested and certified by the Association of Home Appliance Manufacturers (AHAM). It filters a room, at the size of 540 square feet, up to five times in an hour.

The Mighty Purifier has a modern design that suits any room without looking bulky or out of place. You also get to choose between two colors to suit your taste.

Why We Love It

Four-Stage Filtration

The four-stage filtration ensures clean air for you and your family. It includes a washable pre-filter that will remove large particles such as hair and dust. An activated charcoal filter will remove odors, and the true HEPA filter will take care of allergens such as tiny dust particles.
