4 Best Wall-Mounted Air Purifiers: Why Wall Is Best Placement?

Mounted on the wall. That’s the best position for an air purifier. Wall-mounted air purifiers have the best access to indoor air and utilize the existing airflow most thoroughly.

With the best wall-mounted air purifier, you can increase the efficiency of the air purifier by as much as 20% (perfect placement). On top of that, you don’t have to worry about:

  • Air purifier reducing your overall room floor area.
  • Your kid or your dog knocking the air purifier down.
  • Air purifier struggling to generate adequate airflow.
best air purifier that can be mounted on the wall
Here is how a wall-mounted air purifier looks like. Example: #1 Medify MA-35 (check below).

Overall, the wall-mounted air purifiers offer quite a lot of advantages compared to standard floor air purifiers. That’s why it is rather surprising to see a limited portfolio of wall-mounted air purifiers available for residential use.

We have rounded up the best wall-mounted air purifiers on the market, including the best Medify MA-35 and RabbitAir MinusA2 units. You will find the spec-by-spec comparison table of top-rated wall-mounted air purifiers, complete with reviews of each model. You can skip to the comparison table here.

But first, let’s look into why exactly wall-mounted air purifiers have the best placement. Elevating an air purifier 3-5 feet off the ground is a big part of what makes these wall-mounted air purifiers so effective.

Furthermore, we will look what specifications (such as coverage area, CADR rating, filters, noise levels, wattage) you should look for when choosing the best wall-mounted air purifier for your specific situation:

Why Mounting An Air Purifier On The Wall Is So Effective

Most air purifiers are positioned on the floor. It’s the easiest way where to place an air purifier, but it’s not the most effective one.

If you check our article about 7 rules where to place your air purifier, you can see that the #2 rule is ‘Put Air Purifier 3-5 Feet Off The Ground’.

where should i put an air purifier in a room

That’s because you capture both the horizontal and vertical indoor air circulation. At the same time, elevating an air purifier (mounting it on the wall) exposes the unit to the maximum available indoor air allowing it to maximize the indoor airborne particle reduction.

In short, a wall-mounted air purifier is surrounded completely by air from:

  • Up.
  • Below.
  • Both sides.
  • In the front.

With such air purifier placement, the unit can capture the maximum amount of indoor air particulates and increases the indoor air quality very efficiently.

Doesn’t Take Up Floor Or Desk Space

Putting an air purifier on the floor is a bad idea airflow-wise. On top of that, air purifiers do take away your floor space.

An average air purifier will have a length of 15 inches and a width of 10 inches. That’s 150 square inches or a good 1 square foot. It’s not much but if you can find a way you can utilize your wall instead of your floor, why not save yourself some floor space with a wall-mounted air purifier?

kit for installing air purifier on a wall
With most wall-mounted air purifiers, you will get the installation kit included in the package. Example: Medify MA-35 wall kit.

In offices (especially home offices), you will find a lot of personal air purifiers on the desk. That’s a good placement; near to you, 3-5 feet from the ground, you get plenty of access to the indoor air.

However, desktop air purifiers are rather weak in comparison to the best wall-mounted air purifier (below 100 CADR rating, while wall air purifiers can have 200+ CADR rating). On top of that, you don’t want to give away desk space. You might have your laptop there, a cup of coffee, documents, and having a desktop air purifier blowing in your face is not ideal.

That’s why more and more offices are equipped with wall-mounted air purifiers. They are powerful (200+ CADR rating), don’t take away desk space, and can prevent the spread of germs between people as well as reduce indoor air pollutant concentrations.

All in all, wall-mounted air purifiers are quite useful. Let’s look at specific metrics based on which you can tell which wall-mounted air purifier is the best:

5+1 Specs To Check Before You Buy A Wall-Mounted Air Purifier

Air purifiers you mount on the wall are like all others as far as specifications are concerned, with one very important difference (wall installation kit; that’s +1 thing you need to check).

You will find all of these specifications in the comparison table of the best wall-mounted air purifiers below. Here is the quick intro to these air purifier specifications to check (we’ll also include some links for more information):

  1. Coverage Area. Buying a small wall-mounted air purifier for a 500+ sq ft room is not a good idea. Always check that the coverage area of the air purifier matches or surpasses the total square footage of the room/s you want to place the air purifier in.
  2. CADR Rating. Most certainly the #1 metric you need to check out. CADR stands for Clean Air Delivery Rate; it measures the capability of a wall-mounted air purifier to actually remove airborne particulates like dust, smoke, pollen, and so forth. The bigger the CADR rating, the better the unit. That’s why the #1 Medify MA-35 unit (check below) is the best wall-mounted air purifier; it has the highest (290) CADR rating.
  3. Filters (especially HEPA filters). The filtration system is responsible to capture airborne particulates like dust, smoke, pollen, and so forth. All wall-mounted air purifiers have several filters. The most important one is the HEPA filter (reduces at least 99.7% of small 0.3-micron in diameter particles). Air purifiers with advanced H13 HEPA filters are the best since they can capture even smaller 0.1-micron in diameter particles with above 99% efficiency.
  4. Noise Levels. Quiet wall-mounted air purifiers are preferred; you should look for units with below 70 dB levels. The noise levels are less important here than for air purifiers that are used in a bedroom, however.
  5. Power Input (Wattage). This is purely to estimate how much does it cost to run an air purifier. Most air purifiers, including the units mounted on the wall, cost less than $1 to run on 100% output. At 40W max. wattage wall-mounted air purifier, for example, will spend about 1 kWh per day; that’s about 13 cents per day if you take the national average electricity rate of $0.1319/kWh into account.

The +1 specification you should check when buying a wall-mounted air purifier is the inclusion of an installation kit. The two best wall air purifiers you can see below come with the installation kit included. Practically, those are the only true wall-mounted air purifiers on the list.

Based on these specifications, we have compiled a list of the best air purifiers that can be mounted on the wall:

1. Overall Best Wall-Mounted Air Purifier: Medify MA-35 (With 290 CADR Rating)

Coverage Area: Up to 640 sq ft
CADR Rating: 290
Filters: Medical-Grade H13 HEPA

Wattage: 40W
Dimensions (LxWxH): 19.7″ x 25.7″ x 6.9″

Medify MA-35 is the best wall-mounted air purifier on the market. It has a simple and sleek design, a record-high 290 CADR rating for a wall-mounted air cleaner, and can cover areas up to 640 sq ft (given 2 air changes per hour).

Medify is known for their superb H13 HEPA filter air purifiers. Medify MA-35 is their wall-mounted model.

It has a simple 3-in-1 stage filtration system. All three filters – pre-filter for larger particulates, H13 HEPA filter for smallest particles, and activated carbon filter for odor removal – are combined in one filter box. That makes it incredibly easy to install and replace filters.

The key here is the H13 HEPA filter. Most air purifiers use H10-H12 HEPA filters that are great at removing 0.3 micron in size particles. Medify’s H13 HEPA filters remove even smaller 0.1 micron in size particles and improve the air quality more efficiently and quickly.

These filters are exactly why Medify MA-35 is capable of achieving a 290 CADR rating. No other wall-mounted air purifier even comes close to it.

On top of that, it has a large 640 sq ft maximum coverage area and runs at most on 40 Watts (quite energy efficient for the size). It’s perfect for home corridors, office walls, and so forth.

The only con are the bit high noise levels of up to 66 dB.

All in all, Medify MA-35 is the Medify’s air purifier that can be mounted on the wall (with the wall installation kit included). It has those superb H13 HEPA filters, achieves the highest CADR rating (290 CADR on testing), and is quite affordable for such a universal (up to 640 sq ft) wall-mounted air purifier:

Medify MA-35 Review

Pros
  • By far the best wall-mounted air purifier
  • Record-high 290 CADR rating (effectively increases indoor air quality in a short time)
  • Up to 640 sq ft coverage is perfect for offices, kitchen, living room, and so forth
  • Has H13 HEPA filters Medify is known for
  • Made by Medify; a reputable company in air purifier industry
Cons
  • The noise levels can reach up to 66 dB on the high fan speed setting (not ideal)

2. Quietest Wall-Mounted Air Purifier: RabbitAir MinusA2 (Below 45.6 dB Noise Levels)

quietest wall mounted air purifier rabbitair
Coverage Area: Up to 700 sq ft
CADR Rating: 200
Filters: 6-Stage Filtration
Noise Levels: 20.8 – 45.6 dB
Wattage: 7W – 47W
Dimensions (LxWxH): 20″ x 21.4″ x “
Price: $$$$
Rating: 4.6 out of 5 stars

If Medify MA-35 might be a bit too loud for you, the only natural choice is the RabbitAir MinusA2 wall-mounted air purifier. These are both the best air purifiers that can be mounted on the wall.

RabbitAir MinusA2 has two primary advantages over Medify MA-35:

  • It’s a super quiet wall-mounted air purifier. Even at the highest speed, it will generate only 45.6 dB noise levels.
  • It is not exclusively a wall-mounted air purifier; you can also place it on the floor or on a desk.

RabbitAir MinusA2 has an extensive 6-stage filtration system. This includes pre-filter, medium filter, HEPA filter, charcoal-based activated carbon filter, customizable filter (Germ Defence, Toxin Absorber, Pet Allergy, Odor Remover filters – you can choose only one of them), and optional negative ion generator. The whole system gradually removes indoor air pollutants like this:

The design and the filtration system sure seem impressive. However, only a standard HEPA filter and the low noise levels (lower airflow) through the RabbitAir MinusA2 achieved only a 200 CADR rating on testing. That’s not nearly as great as Medify MA-35.

On top of that, while RabbitAir MinusA2 is a superb device, it also has quite a high price (above $500).

It does have a maximum coverage area of 700 sq ft. That means you can mount it on the wall pretty much in any room; kitchen, office, living room, and yes, even in the bedroom due to super-quiet operation.

In short, RabbitAir MinusA2 is one of the two best wall-mounted air purifiers. This is a very quiet yet a bit more expensive one, with great design and a 200 CADR rating achieved in testing:

RabbitAir MinusA2 Review

Pros
  • Quietest wall-mounted air purifier (20.8 – 45.6 dB noise levels)
  • High 700 sq ft coverage area; you can even put it in the bedroom due to low noise levels
  • Aesthetic design
  • It can be mounted on the wall (installation kit included) or placed on the floor or desk
Cons
  • High 200 CADR rating but Medify MA-35 has a higher 290 CADR rating
  • It’s quite expensive ($500+ price tag)

3. Cheapest Wall-Mounted Air Purifier: Webetop HEPA

Webetop wall-mounted air purifier is quite useful. It doesn’t actually need mounting; you just plug it in the outlet. That’s the easy part; the harder part is to get any kind of useful air purification capacity out of it.

Webetop plug-in air purifier does have a 6-stage filtration system, including a HEPA filter. However, the key specification that the testing should show – coverage area, CADR rating, noise levels, even wattage – are missing.

That’s why it’s nearly impossible to review it thoroughly. It does seem like an OK but a small wall-mounted air purifier but its capability to increase the indoor air quality is questionable at best.

Webetop HEPA Review

Pros
  • Plug-in air purifier that can be plugged in wall outlet
  • (Seems) to have an extensive 6-stage filtration system
Cons
  • Specification sheet is missing; we don’t know coverage area, CADR rating, noise levels, wattage
  • Webetop is a no-name brand in the air purifier industry
  • Reviews are ‘mixed’ at best

4. Popular Wall-Mounted Air Purifier: Clarifion

wall mounted Clarifion Filterless air purifier
Coverage Area: Up to 120 sq ft
CADR Rating: N/A
Filters: Negative Ion Generator
Noise Levels: More than 25 dB
Wattage: 1W
Dimensions (LxWxH): 15.4″ x 9.6″ x 2.2″
Price: $$$$
Rating: 0.5 out of 5 stars

Clarifion can be mounted on the wall but it’s not actually an air purifier. It’s a negative ion generator. You can see that it is filterless; it’s hard to make an air purifier without filters.

These negative ion generators usually generate ozone. Now, ozone generator mounted on the wall or not, is either non-effective or plain out harmful as we have thoroughly described in an article about ozone generators.

As such, it should clearly be avoided. Unfortunately, this wall-mounted filterless ‘air purifier’ is quite popular. It seems that quite a lot of people believe that the Clarifion can be used as an air purifier.

The CADR rating – the #1 metric every air purifier should have – is missing from the specification sheet. That’s primarily because Clarifion does not include a HEPA filter and thus cannot effectively reduce the concentration of indoor air pollutants.

This is definitely not a wall-mounted ‘air purifier’ that could increase the indoor air quality in any significant way.

Clarifion Review

Pros
  • Can be mounted on a wall; plugged in an outlet
Cons
  • It’s not an air purifier; it’s a negative ion generator (non-effective or harmful)
  • Has no CADR rating
  • Does not include a HEPA filter
  • Does not increase the quality of indoor air
