Best 10 air purifier for Odors [2020 Reviews]

best air purifier for odors

This guide will introduce 10 best air purifiers for odors with some of my real experiences.

Nobody likes a smelly home. Funky odors in the house are unpleasant and almost always unhealthy. But it’s not always easy to locate where a bad smell might be coming from in your home.  

Odors from pets are one of many common sources of smells that can permeate the whole house. I for one, know the cat litter box can give a pungent smell even if you vacuum around and change the litter religiously. And if it's not that pee stench Charlie left on the carpet, it’s how he smells when he gets a little wet…you know; like a wet dog.

Of course, the bothersome smell isn’t coming from our four-legged friends alone, there’s the draft rising from the smelly basement, odors from damp & mouldy surfaces, and alas, there could also be bad smells coming from the kitchen, especially after cooking strong aromatic and spicy foods.

Overall, it’s not exactly the fresh and clean home you’d hoped your guests and neighbours will see. And personally, I just can’t relax or focus and concentrate on work when a torrent of pungent smells keeps punching you in the face.

So, how do you keep you home odor-free?

There are many ways of dealing with the unpleasant household and pet-related smells in your home. Traditionally, you would take out the trash and scoop the cat litter frequently. You will also draw the windows and vacuum you home dutifully. But the most common method for modern homes has always been to use air fresheners.

However, these -in my opinion- are not really the most efficient techniques. What you are doing here is taking away the physical source but really you have left a lot of airborne pollutants that can give off very strong odors, and even carry allergens that might trigger allergies and respiratory issues. Air fresheners will only work briefly before the odors creep back.

What you want to do if you want to remove odours entirely, is to invest in an Air purifier. These provide fresher, cleaner, odour-free air by filtering out different airborne pollutants. Of course, you will still have to keep your vacuuming routine, and you’ll also have to bath Charlie as usual, but your home will smell fresher in the end.

A good air purifier can clean large volumes of air in an hour. These usually have wide coverage, but larger units can get noisier when turbo mode is on. Smaller compact units clean smaller living rooms, but they really improve the living space in many homes. They run quiet and are dark enough to sit in the bedroom without getting in the way of your sleep.


Air purifier Reviews: Our best 10 picks


1.Germ Guardian AC4825 Air Purifier(Check Latest Price)

Best air purifier for Odours 01

If you’ve been dusting and vacuuming devotedly but still couldn’t beat the dirty and smelly air in your home, it’s time you tried the GermGuardian air cleaning system. This is a 22-inch air purifier that works a treat when it comes to curating healthier living space with better breathing and alleviated allergy symptoms.

It uses advanced 3-in-1 purification and rejuvenation Guardian technology to create healthier homes so everyone breathes free. It utilizes 3 superposed filters; odour reduction stands (pre-filter with activated charcoal), true HEPA filtration mechanism, and UV-C light to create a cleaned-up breathing space all around it. By layering the different filtration mechanisms, this system is able to capture harmful germs, allergens, and dust, kill airborne mould, bacteria, and viruses, and reduce dreadful odors from pet, smoke, and lingering cooking smells.

This is a PCO (photocatalytic oxidation) air cleaner that uses the UV light to excites the titanium Dioxide in the unit to effectively eliminate airborne organic compounds. Instead of simply filtering and trapping allergens, volatile microbes, and pollutants, the system completely destroys them and transforms harmful chemicals into harmless substances. The downside to this, however, is that the unit is not completely ozone free.

Any ozone that could be created is below any detectable level and is well within the guideline limit suggested by the US FDA. And, you don’t really need to turn on the UV if this is a major concern for you. The unit’s activated carbon pre-filter and the True HEPA Filter work like a charm when it comes to purifying and rejuvenating the air in your home.

You’ll love how silent this air purifier runs. It’s the ideal system if you are looking for a system to go in the bedrooms. On low operation, it gives a tender white noise that -together with a warm, ambient LED strip blue light- helps you sleep peacefully in the night.

I find that the filter and UV-C bulb replacement indicator light really makes it easy to maintain this system. If you have busy schedules already, you don’t need to mark your crowed calendar with reminders for replacing your filters…just enjoy the clean, fresh air and when it’s time to replace your filters, the indicator light will turn on.

With an impressive CADR/Watt, you know that your air will be cleaned faster, using the least amount of power. It is ENERGY STAR verified and tested for its high Clean Air Delivery Rate (CADR) so that it goes hard on harmful germs, pollen, dust, pet dander, and tobacco smoke while being mindful of electricity bill budget.

Germ Guardian AC4825 Air Purifier 2

Germ Guardian AC4825 Air Purifier 3


  • Small size and compact to move around your home
  • Incredible discount on all their products
  • Meets strict energy efficiency guidelines
  • Replacements filters won’t break the bank
  • Reduces common odors from pets


  • Uses photocatalytic oxidation so it is not completely ozone free. Leave the UV light off for ozone-free operation.
  • The noise level doesn’t fare too well in quiet places (comparatively)


2.LEVOIT LV-H132 Compact Air Purifier(Check Latest Price)

Best air purifier for Odours 02

This is a sleek, compact but powerful air purifier that quickly creates a noticeable difference in the air quality of your living space. This is small enough to set up neatly on a table or countertop. Its simplistic, glossy white body is a timeless addition to any office space.

In terms of performance, this unit creates a healthy living space with clean and fresh air to breathe. You’ll notice the air quality improving gradually the more you let it run. Its CADR is only at 40 cfm (68m^3/h). This means that it will take the unit an hour or two to satisfactorily clean the air in a 100 sq. ft space. Note that, the CADR only speaks of the rate of purification, not the overall performance of a unit. The LV-H132 may not be the fastest air cleaner, but it certainly provides a better level of air quality, albeit, in a small room.

A 3-speed fan sucks in large volumes of air and channels it through a 3-stage filtration system that captures the dust, smoke, allergens, and other airborne pollutants. There is a fine pre-filter that traps larger particles and helps improve the performance and extend the life of the HEPA filter.

Its true HEPA tackles all the harmful allergens and pollutants that got through past the preliminary filter. At the last stage is an activated carbon filter that gets rid of the horrible smells in the air.

One plus most users appreciate in this unit is its low-noise operation. Being a small unit itself, it has a small fan that runs at 36 dB at the highest. You’ll find that it isn’t louder than the sound on your white noise machine, making it ideal for night time use in the bedroom, or day time use in a home office.

Perhaps the biggest limitation of this unit is simply the room size it is able to handle. Unfortunately, you get about 129 sq. ft. of refreshed air from this unit, which is quite small since most rooms are larger than that. Realistically, however, this is quite the performance, given the size and affordability of this air purifier.

LEVOIT LV-H132 Compact Air Purifier 1

LEVOIT LV-H132 Compact Air Purifier  2


  • Small and minimal Appealing design
  • Quiet operation; can go in your bedroom
  • Efficient three-stage filtration process
  • HEPA filter screens allergens and pet dander
  • Excellent at odor control
  • Ozone free; has a small footprint


  • No basic features like a shut-off timer or filter change LED indicator


3.Germ Guardian AC4100 Table Top Air Purifier(Check Latest Price)

Best air purifier for Odours 03

Now, here’s a 3-in-1 air purifier that you can set on your kitchen countertop to help in the after-meal clean up, removing any food smells that might linger. This is a small but powerful and effective, 11-inch compact-size air purifier that’s ideal for small rooms. It is rated at 68cfm CADR level and can effectively filter the air in spaces of up to 78 square feet.

It uses a three-level filter system that captures dreadful odors, pet dander, and large dust particles in the first filter stage that uses an activated carbon filter. The second level of filtration is a HEPA filter that captures pollen, allergens, and dust mites that slipped through the first level.

The last stage is a UV-c light that activates a photocatalytic filter to kill airborne microorganisms and harmful VOCs. The UV-c light is optional.

The one thing that makes this unit great for office and study room use is its silent operation, even on the high setting.

Overall, it’s an incredible unit that comes at a reasonable price for the features that come with.

Germ Guardian AC4100 Table Top Air Purifier 1

Germ Guardian AC4100 Table Top Air Purifier 2


  • Compact design is ideal for smaller rooms or offices
  • Decent air filtration process
  • Reduces odors
  • Eliminates volatile organic compounds
  • Only 4.85 lbs in weight
  • Smaller footprint
  • Brilliant support from customer service


  • Lacks smart features
  • Lower air changes per hour rating
  • High pitched moan while running on high setting


4.LEVOIT LV-PUR131 Large Room Air Purifier(Check Latest Price)

Best air purifier for Odours 04

You won’t ever want to leave the house if you have the LEVOIT LV-PUR131 refreshing your living space. This is a giant air purifier that moves foul air 360 sq. ft. away, traps allergens and pollutants, and filters the air for a refreshed and revitalized living space.

While the LEVOIT LV-PUR131 isn’t as elegantly designed as their LV-H132 model, in my opinion, it is the firm’s finest creation ever. Design-wise, the increased size allowed the manufacturers to include all the functional and performance features they could not add in the former, more compact models. It also has some pretty dazzling feature sets to amaze the users.

Design-wise, the LV-PUR131 stands out of the crowd with its floating top control panel. In size, this is one of the largest units you’ll find in the market, and it’s likely heavy – obviously not meant to go on the counter or tabletop. Its all-white, minimalist casing Is aesthetically pleasing and would look good sitting on the floor in your living room or bedroom.

It can get quite noisy especially when you have it in Auto mode and it detects debris, pet dander, or dust in the air. The fan automatically runs at full speed to quickly clean up the air. It can get annoying especially if you need to relax and the fan keeps making the noise at different intervals.

Although, I’m never quick to judge this unit on the level of noise. Its performance is amazing. Remember, this is a large unit designed to draw in large volumes of air and clean more than 322 sq. ft of your living space. It is quite effective at that too. It combines three different filters that function to capture the real range of airborne allergens, pollen, dust, pet dander, and bacteria from the air you breathe. The activated charcoal filter removes odors like magic.

If you prefer more compact units that can be moved around different rooms -i.e. the study in the morning, to the living room at noon, and to the bedroom at night- then this wouldn’t be the most suitable air purifier for you. But more compact units will only do a fraction of the job this larger machine does.

LEVOIT LV-PUR131 Large Room Air Purifier 2


  • Higher efficiency for large room

  • Changing filters at 1-2 months can get costly


5.Winix HR900 Ultimate Pet Air Purifier(Check Latest Price)

Best air purifier for Odours 05

What’s interesting about this air purifier is the fact that it is specially designed for homes with pets. So, if you have multiple pets running around the house, you must be interested to see how this unit works. Dogs with long hairs will really keep this unit busy.

There are a few important elements that make this unit great for pet homes. Looking at how this is designed, you can tell it is quite the performer, right off the bat. It uses an innovative design concept that allows polluted air to flow in from the front, sides, and bottom panels. Apart from that, it uses the traditional bottom-top airflow concept common in all Winix models.

The front panel features a perforated grill that makes the unit look rather exquisitely detailed. The side air grills are furbished with a rubber layer so it doesn’t look plain and cheap. And, I dare say, the white colour was an excellent choice for the plastic body.

If you are familiar with Winix air purifiers, you’ll notice that they’ve used exactly the same control panel design and functions in most of their units. Even so, there are some notable features on their Winix HR900 that customers love. Personally, I love the Auto-mode setting that features a smart sensor which responds to any changes in the air quality of your living space.

It turns up the fan speed whenever pollutants are detected and cleans the air in real-time. It goes crazy around the time your dogs are shedding. There is also a Sleep mode that turns down the fan speed and disables the LED lights so that it doesn’t interfere with your sleep. The timer function and child lock feature are pretty amazing too.

Now, if you are wondering about the performance, this unit does really well. It employs a 5-stage air cleaning system that gets rid of most (if not all) airborne pollutants. The first line of defence is the pre-filter which filters larger dust particles and the Ultimate pet pre-filter deals with pet fur and dander.

I love the fact that this is washable, so it’s economical and serves to extend the life of your other filters. Next is the activated carbon filter which deals with chemicals and VOCs in the air, and absorbs pet odors too.

A True HEPA filter captures most of the remaining impurities down to a 0.3-micron responsiveness. Finally, you get an ionizer option which you can turn on to further reduce the amount of pollutants in the air.

This unit has much lower fan power than most giant air purifiers, making it less noisy. The internal structuring of this unit looks well thought so that it gives very silent operation running in its veins. Generally, Winix air purifiers are rated to operate at a threshold of 26 dB -a mere whisper does.

6.RabbitAir MinusA2 SPA-700A Ultra Quiet HEPA Air Purifier

(Check Latest Price)

Best air purifier for Odours 06

This is an elaborate air purifier with practical features fused seamlessly into an avant-garde but artistic slim design. It is sleek, efficient, and smart.

The first thing you notice on this unit is the front panel’s aesthetically pleasing face. Users get to choose from 9 different front panel designs that feature Rabbit Air artist series pictures. I find that it gives the unit a stylish look that really makes it a timeless addition to any living room, study, or kitchen.

And, the fact that you can mount this on your wall makes it all the more desirable. It has a slender profile so it won’t look bulky when put up on the wall.

The control panel fits well into the overall design. The buttons are neatly separated and labelled well for easy understanding from a user’s perspective. A cool feature on this unit is the aspect that allows you to control it from the unit’s interface as well as from your phone.

Yes. You are able to connect it wirelessly to your phone and monitor your air quality and control the unit right from your mobile device.

I’d say, the most noteworthy feature about the Rabbit Air Minus A2 is the six-stage air purification system that comes with it. It is perhaps the most sophisticated purification systems available in the market.

The system features 5 filters and 1 ionizer that work to remove both large particles and ultra-small pollutants like pollen, microbes, and pet dander.

What’s really cool about the filtration system for this unit is the option of selecting customized filters depending on the living environment. You can choose from four filter options so you get the best performance from the unit. The germ defence filter option is best for homes with kids and elderly members who are vulnerable to diseases from particles that carry viruses and bacteria.

The Toxin absorber is ideal for recently renovated homes that often have chemicals and VOCs (volatile organic compounds) floating in the air. Pet allergy filter options work on pet-related impurities like dander, pet hairs, and pet allergens. Lastly, there is an odor remover filter option which is ideal for homes fighting smells from pet litter boxes, aromatic and spiced foods, cigarettes, and even mildew.

7.Winix 5500-2 Air Purifier(Check Latest Price)

Best air purifier for Odours 07

Here’s another one from the Korean-based company, Winix, focused on the home air quality products. Having a reputation of that spans 40 years back, you bet the Winix 5500-2 is an excellent choice for users looking to utilize the power of Plasma Wave Technology to improve the quality of air in their living space.

This is a well-designed air purifier with some practical purification features. It doesn’t look cheap either. On the front panel, you’ll find a 5-function control pane with easy to press buttons. There is also an LED smart sensor that lights with 3 different colours to indicate the current air quality status in your rooms.

This unit combines some remarkable Winix technologies t purify the air in your home. It employs a simple but efficient 3-stage purification system that captures both large and small particles of airborne contaminants.

The pre-filter captures pollutants like dust, and pet hairs. This is attached with a Washable AOC (Advanced Odor Control) Actuated Carbon layer that removes unpleasant odors from the air. The True HEPA filters the remaining contaminants down to a 0.3-micron sensitivity.

Finally, you have the Winix Plasma Wave ionizer that can be activated to not only filter but kill harmful organisms and VOCs and also breakdown harmful chemicals found in the air.

For those who are concerned about having the ion generator run on this unit, they can turn it off at any time. However, theoretically, the Plasma Wave Technology ionizer on Winix units do not emit ozone. There isn’t any risk of irritating asthma or respiratory issue when it’s ON, but the company still makes this function optional.

8.AeraMax 300 Large Room Air Purifier(Check Latest Price)

Best air purifier for Odours 08

The AeraMax 300 is the invention of Fellowes, an American family-owned company that has stood for over 100 years and is reputed to produce some high-end office accessories. This unit doesn’t feature the very best performance functions neither will its design blow away ardent users of high-end air purifiers. Even so, it comes with high-quality air purification systems and practical specs that make a compelling air filtration solution for users who are mindful of their budget.

From the name, you can tell that this unit is able to clean from 300 sq. ft. This is their flagship commercial unit and -in my opinion- compares that the highly praised LEVOIT LV-PUR131. It certainly clean quicker.

I like to think that the only fancy thing you’ll find on this unit is the touch control that comes with it, other features are purely functional, core features. That said, the AeraMax 300 uses the traditional Fellowes 4-stage air cleaning system. Activated carbon filter captures household odors, large dust particles and cig smoke. True HEPA filter filters the remaining airborne contaminants, and the AeraSafe Antimicrobial Treatment filter deals with microorganisms like bacteria, fungi, ad mildew. The last line of defence is the PlasmaTrue Technology ionizer which safely eliminates airborne pollutants.

Overall, this is an excellent mid-range machine that does the job well leaving your home fresh and free of pollutants, all at a reasonable budget.

9.Honeywell HPA300 Extra-Large Room Air Purifier(Check Latest Price)

The function buttons on this unit are located on the top panel. The buttons are neatly arranged in a narrow strip and are labelled for easy identification and operation.

Then there is the True HEPA filter that captures up to 99.97% of the smaller pollutants up to a 0.005-micron sensitivity.
