Best Air Purifier for Bedroom Reviews

Medify MA-25 Air Purifier with Dual Air Intake System

1. Best Overall Bedroom Air Purifier: Medify MA-25

If you’re looking for the best air purifier for a bedroom that’s both convenient and efficient, then this is it.

As you’ll see below, this is the best HEPA air purifier for bedroom allergies because it removes the smallest allergens and dust particles that cause breathing problems at night.

It also cleans the air in large rooms up to 500 square feet, so it’s good for every size bedroom in a home or apartment.

As for the air cleaning performance, you get a 3 stage air filtration system that includes:

  • Pre-filter: Room air must first pass through this filter. The pre-filter traps the largest airborne particles and hair. It also extends the life of the other internal filters.
  • H13 True HEPA Filter: This is one of the most powerful filters on market. It’s a medical-grade True HEPA air filter that captures 99.99% of particles down to 0.1 microns. This includes ultrafine dust, allergens, pet dander, mold spores, bacteria, and more so you can breathe easier at night.
  • Activated Carbon Filter: This filter does two things: 1) removes bedroom odors so the room smells fresher, and 2) removes airborne chemicals and gases (commonly known as volatile organic compounds or VOCs). This results in fewer toxic chemicals in the air that can cause headaches, lung irritation, and irritability while you’re sleeping.

The other stand out features of this small and quiet air purifier that you’ll enjoy are:

  • Dual Air Intake System: Unlike other air purifiers that only draw air in from the front of the unit, this air purifier pulls room air in from two sides. This design makes it much more efficient and faster at cleaning particles out of your bedroom.
  • Dimmable Panel Light: The top control panel can be dimmed or turned off so you can use the air purifier as a convenient nightlight or keep the bedroom completely dark while it’s cleaning the air.
  • Compact Size: This air purifier is small, yet powerful. It measures 13.5″ (H) x 8″ (W) x 8″ (D), so it can easily fit on a nightstand or table inside your bedroom. You can also place it on the floor.

All-in-all, if you’re looking for the best HEPA air purifier for a large master bedroom or small bedroom, then you can’t go wrong by choosing this air cleaner.

It’s one of the most popular and affordable air purifiers for its size and performance.

2. Best Value Air Purifier for Bedroom: Levoit LV-PUR131

Another good air purifier for bedrooms is this unit right here.

This unit has thousands of positive reviews from happy customers and does a great job of cleaning the air of harmful contaminants.

It’s very comparable to our #1 bedroom air purifier review and offers excellent value and performance for rooms up to 360 square feet.

What makes it a better deal for some people is that you can choose between two options:

With the smart Wi-Fi model, you can control this quiet air purifier with your smartphone or other mobile devices.

It also allows you to set up personalized air cleaning schedules throughout the week so that you can keep your bedroom air as clean as possible.

With the VeSync app, you also get air filter change alert notifications.

  • Pre-filter: For trapping the largest particles.
  • True HEPA Filter: For capturing 99.97% of particles down to 0.3 microns in size.

This unit also has a fully Automatic Mode that monitors the air quality and adjusts the fan speed to remove airborne particles at the fastest rate.

We recommend this HEPA air purifier for more than just bedrooms because it offers everything you really need in a good air purifier for any room of the home.

But it’s especially good for people who sleep in average size and small bedrooms that need an efficient air purifier for clean air at night.

Levoit Vista 200 Air Purifier with Night Light

3. Best Quiet Air Purifier for Bedroom: Levoit Vista 200

This is another Levoit air purifier that continues to rank high on our list of bedroom air purifier reviews.

We consider it to be the best small and quiet air purifier for bedroom spaces because of the 360-degree air intake system that pulls room air in from every direction. This feature maximizes air cleaning performance.

Most other air purifiers only draw air in from one or two sides which can increase the decibel sound levels as air passes through the HEPA filter.

As for the internal filters, you get the same high-quality air filters as our previous review, but in a smaller size and combined into a single replaceable filter:

  • Pre-filter
  • True HEPA Filter
  • Activated Carbon Filter

Although this unit has one small air filter for a bedroom, it’s still quite powerful. In fact, this air purifier can handle a room up to 170 square feet, making it a good choice for anyone with a smaller bedroom in the home.

A few other features you’ll also like include:

  • Night Light: This is a good option for any bedroom and it comes with two brightness levels to ensure that you get a better night’s sleep.
  • Timer: This can be set for 2, 4, or 8 hours, and will shut the unit off automatically when the time runs out.
  • 3 Fan Speeds: Low, medium, and high so you can tune the air purifier to your desired noise level and air cleaning needs.

Although it’s ranked as #4 on our list, it should actually be our #1 bedroom air purifier review as it’s certified by the Asthma and Allergy Foundation of America.

The reason we didn’t list it first is that many people are looking for a small air purifier for bedroom and this unit has enough power to clean the air in the largest rooms.

What makes this air purifier so good is the fact that it uses a 6 stage air purification and deodorization system.

In fact, it’s the top leader in the industry for cleaning the most pollutants from your indoor air. So if you’re serious about getting the best air purifier for sleeping, then you should highly consider this unit.

  4. Customized Filter: (See details below)
  5. Activated Carbon Filter: For reducing bedroom odors and volatile organic compounds.
  6. Ionizer: For revitalizing the air and making it easier for the internal air filters to trap particulates like dust, allergens, mold spores, and other pollutants.

With all of those air cleaning technologies combined, there are no particles that this air purifier can’t remove inside your bedroom.

The customized filter option also allows you to fine-tune this air purifier even more, including:

  • Germ Defense Filter: Reduces airborne bacteria, mold spores, and particles that carry viruses.
  • Pet Allergy Filter: Reduces pet dander, pet allergens, and pet hair.
  • Toxin Absorber Filter: Reduces heavy volatile organic compounds (VOCs) and other chemicals.
  • Odor Remover Filter: Reduces odors from pets, cigarettes and cigars, cooking, and mildew.

Another top feature for this bedroom air purifier is that it can be wall-mounted or stand alone as a floor unit. That gives you plenty of options for where to place it in your room.

The front panel comes in two color choices and multiple designs.

A Wi-Fi enabled version is also available if you want total control from your iOS or Android device regardless if you use it as a floor unit or mount it on the wall.

Best of all, this super quiet air purifier for a bedroom can clean the air in a room between 700 to 815 square feet. That makes it a good choice for big master bedrooms and basement bedrooms.

However, this unit also works extremely well in small bedrooms too, especially if you’re looking for a top air purifier for bedroom allergies.

All-in-all, this is the most advanced air purifier you can buy today for your bedroom.

  • True HEPA Filter: For capturing 99.97% of microscopic particles that cause respiratory issues in children.
  • Activated Carbon Filter: For eliminating harmful volatile organic compounds (VOCs) and child room odors (i.e. diaper pail).
  • UV-C Light: For safely destroying microorganisms that are known to make children sick (bacteria, viruses, and fungi). The UV-C light destroys the DNA makeup of microorganisms and pathogens.

GermGuardian AC5350 Air Purifier (2 colors)

7. Best Air Purifier for Bedroom Germs: GermGuardian AC5350

If you liked the idea of our previous bedroom air purifier review, but wanted something that could save a bit more floor space, then you’ll want to consider this unit here.

This GermGuardian air purifier comes in two colors: black and white.

It also has all of the same powerful air cleaning technologies as the PureZone unit:

  • True HEPA Filter
  • Activated Carbon Filter
  • UV-C Light

The GermGuardian brand is well-known for its germ-destroying capabilities and every air purifier designed by this company includes a powerful UV-C light.

And because this air purifier includes a UV-C light to kill off bacteria, viruses, and mold spores, we recommend it as the best air purifier for bedroom germs in rooms up to 167 square feet.

If you have a large bedroom, then you should consider using two or more units to cover the space. This is especially true for basement bedrooms.

Having a UV-C light is essential for bedrooms in the basement because mold and bacteria growth is common in that area of the home.

But having an air purifier that can eliminate those types of particles from the air is good for any level of the house, and can reduce musty smells and damp odors so your home smells fresh.

Blueair Blue Pure 411 Air Purifier with HEPA Filter

8. Best Rated Air Purifier for Small Bedrooms: Blueair Blue Pure 411

According to Consumer Reports, Blueair makes one of the best air purifiers that’s rated as “excellent” for particle removal at both the high- and low fan speed settings.

The model they’re referring to in that review is the Blueair Blue Pure 211 air purifier.

However, the Blue Pure 211 is designed for rooms up to 540 square feet which is larger than most bedrooms.

Therefore, the Blue Pure 411 is the next best HEPA air purifier for bedroom locations.

This air purifier covers up to 185 square feet—making it a good air filter for small bedrooms.

This unit also includes the same high-quality air cleaning capabilities as the larger Blue Pure 411 unit:

  • Fabric Pre-filter: This is a machine-washable stocking that slips over the bottom half of the air purifier and comes in six color choices. The pre-filter captures the largest particles like dust, dirt, and hair, thus prolonging the life of the main HEPA filter.
  • HEPA Filter: This captures microscopic pollutants down to 0.1 microns in size. (See below for how it works.)
  • Activated Carbon Filter: This reduces odors and airborne chemicals and gases.

While the HEPA filter in this air purifier is not the True HEPA type, it actually captures smaller particles that other air purifier units.

It does so by using HEPASilent filtration technology which is equal in efficiency to True HEPA filters while using less energy and less noise.

And according to Blueair, “Airborne particles are charged before they reach the filter. This makes the particles adhere to the polypropylene fibers in the filter more easily due to electrostatic forces, which allows the use of a less dense filter, so more air can be pushed through with less noise and less energy. The lower filter density allowed by the stickiness of the charged particles also reduces clogging. Filtration remains at peak performance levels longer, with high efficiency and longer-lasting performance.”

So if you want an industry-leading HEPA air purifier for your bedroom that can remove dust, allergens, mold spores, smoke, and other particulates from the air, then this is a top choice for you to consider.

Dyson Pure Cool Me Air Purifier with 360-Degree HEPA Filter

9. Best Air Purifier Fan: Dyson Pure Cool Me

As you probably already know, Dyson is a top brand for household appliances.

And this air purifier is no exception.

While it’s one of the more expensive air purifiers for bedrooms, it does come with an added bonus that you won’t find on other air cleaning units: a cooling function.

This air purifier doubles as a fan and delivers a stream of purified air and cool air while you sleep. And for many people, that’s more than enough reason for buying it.

However, this air purifier also comes with some more advanced features:

  • 360-Degree HEPA Filter: Captures 99.97% of allergens and pollutants that are found in bedrooms.
  • Core Flow Technology: This allows you to precisely adjust airflow to deliver personal cooling with purified air. By adjusting the dome’s position, you can change the airflow angle of the air purifier.
  • 70-Degrees of Oscillation: This rotates the unit from side to side to deliver purified and cooled air more efficiently.
  • Night-Time Mode: This mode puts the air purifier in a quieter setting with a dimmed display while still automatically monitoring the air quality in the bedroom.
  • LCD Display: This shows airflow speed, modes, and filter life.

It’s also one of the best air purifiers for bedroom allergies because it has been certified by the Asthma and Allergy Foundation of America.

So if you’re looking for a dual-unit: one that can cool you down and clean the air in a bedroom, then this is a good choice for medium size rooms up to 290 square feet.

Bedroom Air Purifier Buying Guide

If you need more information on what does an air purifier do, then this section can help.

Below you’ll find out more about each type of air filter for bedrooms as well as get answers to common questions people have about these devices.

Air Filter Types

Air purifiers contain various types of air filters to clean the air.

Here’s how each one works:

  • Pre-Filter: This filter acts as the first line of defense on an air cleaner. It’s a mesh filter that’s washable. As room air passes through this pre-filter, it traps the largest particles, such as dust, dirt, and hair. By collecting those larger contaminants on the pre-filter, the other internal air filters can work more efficiently at removing the finer pollutants.
  • HEPA Filter: This is an essential filter for every good air purifier. The True HEPA type is the best kind of air filter you can get. That’s why every best bedroom air purifier we recommend on this page has it. To be classified as a True HEPA filter, the air filter must be certified to capture 99.97% of particles down to 0.3 microns in size. This includes the most common pollutants found in a bedroom, such as ultrafine dust, allergens, mold spores, bacteria, etc. Some air purifiers, like Blueair and IQAir, use a variation of a HEPA filter to maximize efficiency. While they’re not technically “True” HEPA filters, those alternatives are still superior to standard HEPA filter air purifiers.
  • Activated Carbon Filter: If you want to reduce bedroom odors or toxic volatile organic compounds (VOCs) that are commonly found in the air, then this filter is your only defense. It contains millions of tiny pores that cause airborne gases and chemicals to stick to the surface as air passes through the filter.
  • UV-C Light: One aspect that all large and small air filters for bedrooms lack is the ability to kill airborne bacteria and viruses. A HEPA filter can trap bacteria but virus particles are too small and therefore pass right through it. A UV-C light is a powerful technology to have on an air purifier in a bedroom because it can destroy airborne microorganisms and pathogens. As air passes by the light while filtering through the air purifier, the UV-C light disrupts the DNA structure of these particles, and thus, renders them harmless to your health. If you want the best air purifier for bedroom that eliminates particles that can make you sick, then look for this feature.
  • Ionizer: This is a handy feature to have on any air purifier because it helps the unit to work more efficiently. Ionizers emit charged ions into the air that latch onto particles like dust, allergens, smoke, and mold spores, and this bond causes those pollutants to become heavy. As these particles increase in weight, they’re more easily pulled into the air purifier’s filters. It also causes some of these contaminants to cling to surrounding surfaces so that they don’t float around in your bedroom air.

Common Questions About Air Purifiers and Bedrooms

Best air purifier for bedroom

What is the Best Air Purifier for a Bedroom?

The best air purifier for a bedroom is the Medify MA-25. It offers the highest quality HEPA filter, user features, and room size coverage of 500 square feet; making it good for every size bedroom.

The Medify MA-25 also comes in two color choices: black and white, to better match your existing bedroom décor.

The most notable features in addition to the powerful air filtration are the tempered glass panel, 3 fan speeds, 8 hour timer, night mode, and child lock.

You won’t find a better deal on a good bedroom air purifier with high efficiency and a low price than the Medify MA-25.

What is the Best Air Purifier for Bedroom Allergies?

Best air purifier for bedroom allergies

The best air purifier for bedroom allergies is the Rabbit Air MinusA2. It is certified by the Asthma and Allergy Foundation of America to get rid of airborne allergens and other particles that trigger allergies and asthma to occur.

The Rabbit Air MinusA2 offers a number of customizations as well. It comes in multiple colors and designs, can be wall mounted, and allows you to choose between four customized filters to get the best air filtration for your bedroom needs.

You can also choose a Wi-Fi version for wireless control.

This unit is best used in large rooms between 700 to 815 square feet but is good for practically any bedroom of any size. If it’s used in a smaller bedroom, then it will become even more efficient at cleaning the air and filtering out airborne pollutants.

We consider it to be the best HEPA air purifier for allergies.

What is the Best Location for an Air Purifier in a Bedroom?

The best location for a bedroom air purifier is about 6 to 10 feet from the head of your bed. You also want the purified air flow to be pointed toward your head. This position will allow you to receive the most benefits of breathing filtered air.

The closer you can get the air purifier to your immediate breathing zone, the less concerned you have to be with the question, “what size air purifier do I need?”. However, it’s always good to get the right air purifier room size so that the entire bedroom air can be filtered.

Do Air Purifiers Help You Sleep Better?

Air purifiers can help you sleep better by removing airborne particles like dust, pollen, allergens, mold spores, smoke, and pet dander that cause congestion and irritate your lungs at night. When you use an air purifier in your bedroom, you can sleep better and wake up feeling more refreshed.

According to this double-blind randomized cross-trial on patients with perennial allergic asthma, “clean air, administered directly to the breathing zone during sleep, can have a positive effect on bronchial inflammation and quality of life in patients”.

The study discovered that by decreasing allergen exposure in the room where a person was sleeping, bronchial inflammation lowered during the treatment period.

Participants in the research enjoy more uninterrupted sleep which lead to a better quality of life. Therefore, the positive effects of using an air purifier in the bedroom can be achieved by people with perennial allergic asthma by minimizing the exposure to inhalant allergens.

If you have asthma, then any of the air purifiers reviewed on this page are a good choice. You can also check out our best asthma air purifier guide for more options.

Additionally, several research articles indicate a link between cardiovascular diseases and sleep deprivation. These interactions can manifest as a number of issues, including hypertension, myocardial infarction, and congestive heart failure.

One study on particulate air pollution and carotid artery stenosis demonstrated that outdoor fine particulate air pollution (mass concentration of particles <2.5 μm in diameter [PM2.5]) is associated with cardiovascular mortality and ischemic heart disease events. “PM2.5 is independently associated with carotid artery stenosis (CAS), an important risk factor for cerebrovascular disease and stroke. These results support the relationship between fine particle air pollution and prevalent atherosclerosis, and may suggest a pathway through which PM2.5 increases cardiovascular risk.”

Based on these studies as a whole, we can conclude that if you reduce the level of air pollution inside a bedroom, then a reduction in cardiovascular diseases and sleep deprivation can be experienced in some individuals.

If you’re particularly worried about the types of particles in your bedroom air, consider getting an air quality monitor along with a new air purifier. Air quality monitors detect and report the level of pollutants in the air so you know exactly what’s floating around while you sleep.

Our guide on the best home air quality monitors here is a good place to start your research. It includes our expert recommendations and detailed information on how these units work for your benefit.

Can You Sleep with an Air Purifier On?

You can sleep with an air purifier on without any problems. It’s advised that you do sleep with an air purifier running. Sleeping with an air purifier on will keep the air around you clean, which can help you breathe better and experience less congestion.

But are air purifiers good for people of all ages? Yes. Everyone can benefit from the use of an air purifier being on at night, regardless of their age: air purifiers are safe for babies.

Air purifiers can remove dust and dust mites, air purifiers do help with asthma and allergies, and some air purifiers do remove odor, which is good for everyone.

Is it OK to Leave an Air Purifier On All Night?

It is OK to leave an air purifier on all night and you should. The more time an air purifier has to cycle the air at night, the cleaner the room air will become. Air purifiers are designed to run all day and night to maximize their efficiency.

It’s also a good idea to keep the door to the room shut. That way, the air will get recycled over and over again through the HEPA filter until it’s as fresh and clean as possible.

The Centers for Disease Control (CDC) reports that one-third of U.S. adults get less than the recommended amount of sleep, which is 7 to 9 hours. And not getting enough sleep is associated with many chronic diseases and conditions, including type 2 diabetes, heart disease, obesity, and depression.

A good air purifier in the bedroom can help improve your overall sleep habits and it’s best to leave it on all night to feel the most positive effects.

Most of the best home air purifier models include data on the Clean Air Delivery Rate (CADR). This measurement reveals how efficient the air purifier is at cleaning the air in a particular size room.

The CADR rating tells you how effective the air purifier is at removing three types of contaminants: dust, pollen, and smoke. The higher the numbers are for each pollutant, the better the unit’s efficiency.

If you have trouble sleeping at night due to smoke, then it’s best to get a good air purifier for smoke that has a high CADR rating. The same thing is true for people with allergies related to dust or pollen.

Does Every Room Need an Air Purifier?

Not every room needs an air purifier. Each room in your house is used in different ways so you may or may not need it. Most modern air purifiers are easy to move from room to room, so you can move them around as you need. But it’s always good to get the best air purifier type for each room size.

A good rule of thumb is to have an air purifier in the rooms you frequent most. For most people, this includes the bedroom and living room.

The benefits of air purifiers also outweigh the initial cost. By having more than one air purifier in your home, you can make sure that the air you breathe is as clean as possible in the rooms that you’re routinely in. A good air purifier odor remover will also help your rooms smell better. Plus, with multiple units inside the home, you won’t have to carry the air purifier around which can be cumbersome on a daily basis.

So are air purifiers worth it throughout the house? Yes, but you don’t have to go overboard and purchase one for every single room. But if you do, then you may want to consider a top air purifier with reusable filter as a way to save on yearly maintenance costs.

You can also browse through our list of the best cheap air purifiers to see what’s available.

How Long Does it Take an Air Purifier to Clean a Room?

An air purifier can clean the air in a room between 15 minutes to one hour. The rate of air purification depends on three things: 1) the room size, 2) the fan speed, 3) and the efficiency of the air filters.

The ACH rating, short for Air Changes Per Hour, tells you how many times per hour the air purifier filters the air. For example, 2 ACH is two times per hour while 4 ACH is four times per hour. More is better.

On average, most air purifiers can clean the air four times per hour (every 15 minutes). However, no matter how long it takes an air purifier to clean a room, every unit does a more effective job when the door is closed so that the air can be recycled over and over again to remove the pollutants.
