How Do We Measure?
Price and value There are still plenty of hidden gems that offer exceptional values for a mere 50 dollars. During our research and comparison, we will run down the specification, brand reputation, filter availability on every air cleaners we reviewed. Hence, the low price point is not the only determining factor here. The quality of the filtration, airflow delivery rate, add-on features, reliability, and durability will be the main driving factors instead.
HEPA filter A HEPA filter is a must regardless of how cheap the air cleaner is. High Efficiency Particulate Air or HEPA is a mechanical filter that traps fine particles in the air that cannot be seen by our naked eyes. It is proven, safe, and effective in providing clean air to the masses. Doesn't matter if the air cleaner is using a top grade HEPA filter or lower grade HEPA-type filter (99% efficiency/ 2 microns), having a HEPA filter is our minimum criteria.
Carbon filter A great complement to a HEPA filter, a carbon filter can remove smoke and odor particles via chemical absorption. As harmful smoke is a known trigger for allergies and asthma, not having one equipped can undermine an air purifier that costs less than 50 dollars. Extra bonus point will be given to a model that uses a standalone carbon filter than a carbon pre-filter.

Breathe easier and wake up free from nasal congestion with hOmeLabs 4-in-1 Compact HME020020N. A small yet capable air cleaning device that will only cost you under 50 inclusive of filters. Do not underestimate this air cleaner though. hOmeLabs comes with an advanced 4-stage filtration including an optional ion booster. For the low price, you will get a standard 2 fan speeds and a filter changing indicator letting you know when it is time to change the cartridge filter.

Measuring at a boxy 6.7 inches diameter, 7.5 inches height, and a mere 2.9 lb weight, you can fit hOmeLabs HME020020N in any room space. In fact, the compact travel size means you can conveniently bring it to the office during day time and back home during night time. Operating the air purifier is dead easy with air inlet at the front and output at the top. Overall build quality is superb, supported by a 2-year warranty plus an extra 6-months when you sign up on hOmeLabs website.

hOmeLabs HME020020N 4-in-1 is excellent for bedroom and office use with its whisper-quiet operation. At the lowest speed, there is absolutely no noise coming from the machine even when placed right next to you. Power usage is also low due to its airflow output and size. Compared with most kitchen appliances, hOmeLabs will not add any burden to your electric bill.

Let's dive into hOmeLabs 4-in-1 compact air purifier specification:

  • Filtration Type - 4-stage
  • Air Filtration - Pre-filter, HEPA filter, Carbon filter, Ion Booster
  • Noise Level - Silent
  • Warranty - 2 years
  • Coverage Area - 40 sq. ft.

For less than 50 bucks, hOmeLabs HME020020N comes with the game-changing 4-stage filtering system that is not even found in premium models. The first-stage pre-filter blocks large particles mainly dust, hair, and debris while extending the HEPA filter usage life. The HEPA filter will remove 99.97% of fine particles up to 0.3 microns in sizes like pet dander, pollen, mold, and bacteria. The carbon filter reduces smoke fumes, pet smells, kitchen and cigarette odors. Lastly, the ion booster releases 3 million negative ions per cubic centimeter to pull airborne contaminants for the filter to capture. Due to its compact size and small coverage, hOmeLabs 4-in-1 air purifier is best used in a dorm, bathroom, work desk, closet, or bedside table. Enjoy a completely freshen, purified air with just a couple of hours of runtime.

Replacing hOmeLabs HME020020N 4-in-1 air purifier filter is super easy and affordable at only around 26 to 34 dollars annually. Simply detach the bottom cap by rotating counter-clockwise until you hear a click, then swap the used all-in-one filter with a new one. You should change the filter every 700 hours or 6 to 8 months depending on the room air quality.

So what is the downside for such a price-cheap air cleaner? The limited 40 square feet coverage is the most obvious one. You will need to place hOmeLabs HME020020N close to you for optimized air cleaning. Smoke and odor filtration are slightly weak compared with other types of pollutants. Autonomous mode or supporting features are also non-existence either. A common theme you will see in the listing here. Finally, the filter usage life is still short of our 1-year benchmark even though understandably so.

In short: A compact air purifier that can help you live and breathe healthier. For less than 50 dollars, you'll get a complete 4-stage filtration including a HEPA filter and ion booster.

Safety-wise, PARTU BS-03 is FDA, ETL, FCC approved and comes with 2 years manufacturer warranty with lifetime support. A good stamp of assurance on its durability and reliability.

The smaller dimension also means power usage and noise level is on the lower side. Anticipate 38 to 59 dB white noise that is suitable for night use as long as the fan speed is kept low. The energy-efficient 12-watt power output will save you some dollars in the long run. You can leave PARTU BS-03 running silently all-day unattended while you go on with your daily life. Perfect for bathroom table, bedroom, baby room, or work desk that needs fresh air without the noise distraction.

Here's what a small air purifier manages to fit in its specification:

  • Filtration Type - 3-stage
  • Air Filtration - Fine Preliminary Pre-filter, True-HEPA filter, Activated carbon filter
  • Noise Level - 38 - 59 dB
  • Warranty - 2 years
  • Coverage Area - 107 sq. ft.

On the filtration side, PARTU BS-03 is well-supported by a dependable 3-stage HEPA system. Starting with the pre-filter that focuses on collecting dust debris that may clog the HEPA filter from functioning properly. This is closely followed by the must-have HEPA filter that removes 99.97% of smaller PM 2.5 particles that bypassed the pre-filter like dues mite, pet dander, mold, pollen, and germs. Finally, the activated carbon filter will get rid of harmful smoke and odors coming from indoor and outdoor. Adding a mild 107 square feet into the equation, you have yourself a powerful yet inexpensive air cleaner with low upkeeping. Dust, mold, pollen, pet dander, germs, and chemicals will be removed with ease.

For the affordable price tag +- 50, PARTU BS-03 is a bargain that comes with everything you need.

There is also a fragrance design drop slot to insert your favorite essential oil. Choose any fragrance design sponge e.g. Citrus, Honeydew Melon, Quince, Musk, Vanilla, Orris, Vetiver that helps you relax and sleep while PARTU BS-03 purifies the air.

Let's talk about the few negatives of the air cleaner. The airflow circulation is slightly under par thus it can only cover a small room size. The lack of a built-in sensor, timer, and auto/ sleep mode is expected but the inclusion would be nice. The smaller filters also require quarterly change that can be a slight hassle for some, not to mention the extra filter cost to bear. Ignoring the few drawbacks and you will have yourself a solid entry-level air purifier for home use.

In short: At around 50 after the discount, PARTU BS-03 exceeds what a HEPA air cleaner could achieve at its price range. A sensible starter choice for a person that doesn’t want to spend too much money on an air purifying device.

It is very rare you will find a big brand like Levoit air purifier for around 50 dollars. Levoit LV-H128 is exactly that and even comes with a dual top-grade H13 HEPA filter. Out of all of the models listed here, this South California designed air cleaner is perhaps the best to refresh the air in your workspace and home.

At a diameter of 6.7 inches and a height of 10.4 inches, Levoit LV-H128 is small enough for desk use but not portable to bring along for travel. The 3.3 lb weight is light enough to carry it around from room to room. Surrounding the white exterior is the side air inlet with an air outlet at the top. The fitting quality is tight with no trace of harmful gas detected. As with all Levoit air cleaners, LV-H128 has the safety assurance of being ozone-free, AHAM, CARB Certified G-20-206 certified, and UL/ ETL listed. It is also backed by an assuring 2 years warranty with California-based customer service. Suitable for a home with children and pets.

Another highlight of Levoit LV-H128 is the built-in aromatherapy feature. By combining the air cleaning with stimulating fragrances, it can create a clean and comfortable environment for you to work, focus, and relax. Simply remove the aroma cap and add 2 to 3 drops of essential oils to the aroma pad for instant reinvigoration. Choose from Lavender, Peppermint, Citrus, Honeydew Melon, Musk, Vanilla, Orris, Vetiver, to Rosemary.

The silent air cleaning helper. Levoit LV-H128 can help you achieve soundly sleep every night with its low noise output. Noise output is only 24 dB at the lowest speed up to a whispering 36 dB at max speed. Sadly sleep mode is not included so you will have to manually adjust the fan speed before you hit the sack. Power consumption is very low with only 6 watts hourly (low speed). You can safely leave it on the whole day without having to worry about overheating or electrical bills.

Here is the key specification of Levoit LV-H128 air purifier:

  • Filtration Type - 3-stage
  • Air Filtration - Polyester Pre-Filter, H13 True HEPA Filter, Activated Carbon Filter
  • Noise Level - 24–36 dB
  • Warranty - 2 years
  • Coverage Area - 161 sq. ft.

A proven technology has been trusted by 3 million Levoit customers worldwide. Levoit LV-H128 is built around the H13 HEPA filter to collect a variety of household contaminants in the air. The outer polyester pre-filter traps large particles like dust, lint, fibers, hair, and fur. With most particles blocked from proceeding, the H13 True HEPA filter capture 99.97% of dust mites, mold spores, pollen, pet dander, and other fine particles as small as 0.3 micrometers. The activated carbon filter absorbs unwanted smoke and odors from the pet litter box, cooking, tobacco smoke, and VOCs. No fancy ionizer or UV-light can be found here. It is the purest 3-stage filtration system you can get.

Despite its small size, Levoit LV-H128 air purifier has a decent 161 square feet coverage area. Powerful enough to feel the air quality different with 30 minutes of high-speed air circulation. Best used as a desktop in home office, nursery home, studio/ small apartment, basement, and bedroom where you spent the most time in.

There are few common drawbacks for such a price-constraint air cleaner. Besides the standard filter change indicator, the lack of support features is unavoidable in the spec sheet. The smaller filter also means you have to replace it more regularly and the cost could go as high as 40 dollars. The airflow delivery rate is not the greatest either so smoke particles may already settle down before the air cleaner has the chance to capture them. Then again, we are nitpicking on the few notable issues. Treat Levoit LV-H128 as an affordable desktop air purifier and you will be just fine.

In short: Affordable air purifier equipped with dual H13 HEPA filters. Effortlessly remove stubborn household pollutants while also relax your mind through aromatherapy.

The first fine preliminary filter neutralizes dust, hair, and other larger contaminant in the home. Next, the true HEPA filter captures 99.97% of household PM 2.5 as small as 0.3 microns including pet dander, mold spores, pollen, and germs. Activated carbon filter eliminates chemical fumes from cigarettes, cooking smoke, and pet odors.

Combining the efficient 360° air intake and discharge, KOIOS EPI810-A can maximize air circulation in your room.

At less than 2 watts or 0.002 units of power consumption, you can safely leave it running all day at almost no cost to you.

On to the things we don't like. The short 6 months filter lifespan is the norm here for this budget segment. The small airflow delivery rate also translates to limited capacity, particularly against smoke. Besides the filter change indicator that alerts you to replace the filter when time is up, there is nothing going on with KOIOS EPI810-A. We can let go of the timer, but the lack of Auto mode and sleep mode is a big turn-off. Still, this is an entry-level HEPA air purifier that will not cost you more than 50 dollars, what else could you ask for more?

In short: A whisper quiet, energy-saving, True HEPA air purifier for less than 50 dollars. The no-fuss compact design makes it the perfect bedroom and desktop air cleaning machine.

A clean yet functional design with surrounding ventilation and single top button control. Operating Mooka 3-in-1 EPI810 is one of the easier tasks where even children can do it. Just press once to turn on the device and again to cycle the 2 fan speeds. No complicated controls are needed for this simple device.

The perfect desktop and bedstand air cleaning machine for everyday use. At a familiar cylinder 6.9 inches in diameter, 7.5 inches in height, and under 3 lb in weight, portability will never be an issue. You can bring it to your work desk during the morning session and bring it to your room at night time. Like most conventional 3-in-1 air cleaner that does not rely on ionizer, Mooka EPI810 is 100% ozone-free as certified by CARB. It also achieved all the safety standards from Erl, FCC, and CE. To put the icing on the cake, there is a standard 3-years warranty that covers all manufacturing defects. This should end all doubts that an air purifier the costs less than 50 is unreliable.

Here's is what you get for the price you paid:

  • Filtration Type - 3-stage
  • Air Filtration - Pre-filter, True HEPA filter, Activated Carbon filter
  • Noise Level - <35 dB
  • Warranty - 3 years
  • Coverage Area - 156 sq. ft.

The workhouse 3-in-1 HEPA air filtration existed for a few decades. When dirty air is pulled inside the air purifier, the preliminary filter will capture visible contaminants like dust, hair, and debris from the air. With most dirty particles captured, the True HEPA filter traps non-smoke allergens up to 99.97% efficiency as small as 0.3 microns. Activated carbon filter removes gas particles such as pet odor, cigarette smoke, and cooking smell around your living space area.

Supporting the 3-in-1 purification is the 360° air intake that can take out pollutants at all angles. At full speed, the air purifier can cover up to 156 square feet of space like a bedroom, storeroom, studio, and small apartment. With no harmful byproduct produced, Mooka EPI810 3-in-1 air cleaner is suitable for the elderly, pregnant women, children, and those suffering from chronic diseases.

Most of you would probably leave Mooka 3-in-1 EPI810 in the bedroom as that's where we spend the most time in. With less than 35 dB in noise output, we would agree that Mooka EPI810 is fitted to do so. To top off the silent purification, there is a built-in night light that added a sense of comfort and security, particularly for children. It can also help you navigate through the dark and avoid hitting on objects when you are trying to head to the bathroom middle of the night.

For power consumption, Mooka 3-in-1 EPI810 is one of the most energy-efficient home appliances out there. It only uses between 2 to 8 watts of electricity hourly. We recommend disabling the night light and leave it running 24x7 for a comprehensive air cleaning.

Let's quickly touch on the cons as we are repeating ourselves. You have to settle with the cheap but short filter cartridge life. The limited airflow does not bold well in removing toxic fumes. Mooka EPI810 also lacks cleaning features other than the filter change indicator. These are the few setbacks you just have to contend with at this price range.

In short: For less than 50 dollars, Mooka EPI810 ticks all the bills as a 3-in-1 HEPA air purifier. It may not have an outstanding airflow distribution, but for home use other than the living hall, it will fit in just fine.

For just around 30 to 40 dollars, JINPUS GL-2103 HEPA air purifier can help improve indoor air quality for you and your family member. Capable of running it through a USB port, the extended 1.5 Meters USB cord allows you to run it further away from the power source. A rare but useful feature that is hardly seen in an air cleaner.

One of the perks of a compact air purifier is easy to use one-touch control. Press once to turn on the device, twice to activate Sleep mode, and again to turn it off. At a compact 4.9 diameter, 7.6 inches height, and 1.2 pounds in weight, this compact air purifier will fit into your home décor without being too cumbersome. The plain white body has a minimalist touch with soft decorative blue light. By no means the design feel premium though. Durability should be good as it only houses basic functionality. Like RIGOGLIOSO, it is CE RoHS certified with no harmful byproducts produced.

Here are the impressive features of JINPUS GL-2103 air purifier:

  • Filtration Type - 4-stage
  • Air Filtration - Fine Preliminary Filter, True HEPA filter, Activated Carbon filter, Negative Ion Generator
  • Noise Level - ≤30 dB
  • Warranty - 1 year
  • Coverage Area - 107 sq. ft.

Despite its compact size, JINPUS GL-2103 comes with a quadruple filtration that is not even found in a full-sized console air purifier. Upfront, you have the standard fine preliminary filter that blocks larger particles and protects the HEPA filter. The True HEPA filter will target finer particles to capture like mold, pollen, dust mite, pet dander. The activated carbon filter will remove common sources of smoke e.g. food smell or cigarette odor puffed out while you're working. The negative ion generator will release millions of ions that merge and pull down airborne impurities for the filter to capture. It is safe and will definitely help curb down your allergies from triggering due to poor air quality.

With the official airflow delivery rate of 51-150 m³/h, JINPUS GL-2103 is best used in small room spaces like office room, bedroom, washroom, or kitchen. Even if you are not a hypersensitive person, you can truly benefit from the air purifier.

JINPUS GL-2103 HEPA air purifier comes with a low noise output of 30 dB. In Sleep mode, it is whispering quiet even if you place it next to use while you work. You can also use it in the bedroom as it will not disturb your sleep. The only annoying thing is the light does not dim down enough which can be annoying for some.

For power consumption, GL-2103 is very energy-friendly as it uses less than 2.5 watts of electricity hourly. Given it can be powered by a USB, you don't have to worry about any incurring cost other than the filter replacement.

Surely there are some negatives associated with a USB-powered air purifier that we should not overlook. First, the filtration performance is not that great given its size. At high speed, the purifying coverage can only go as high as 107 square feet at low air changes per hour. The sleep mode function comes with an annoying 8 hours countdown timer and does not completely turn off the indicator light. The filter quality and size could do better particularly against chemical fumes like ammonia, formaldehyde, and benzene. The only saving grace is the all-in-one filter cost 28 dollars annually even if you need to replace it twice a year.

In short: A very compact 4-stage USB air purifier with a True HEPA filter. For around 30 dollars, it comes with a negative ion generator and night light but at a trade-off in performance.

RIGOGLIOSO is the perfect gift under 50 for your parents, office mates, and friends as everybody could do with cleaner air. It comes with a full set of filters plus a night light function that creates a chilling atmosphere. At a total 1.5 pounds weight plus small 4.9 diameter and 7.6 inches in height, it is very lightweight and portable where you can bring it anywhere with your laptop. The design may not look as grand as others, it is still very durable despite the plasticky built. There is no harmful byproduct released from the case as certified by CE RoHS.

Moving to controls, the one-touch switch is very easy to use and surrounded by a delicate blue LED light. Press once to turn on the device, twice to activate Sleep mode that will also dim the light, and third time to turn off the unit. Another thing to boost RIGOGLIOSO usability is the long 1.5 Meters USB cord to power the air purifying machine. You hardly see this feature in an air cleaner, let alone a True HEPA air purifier.

There are plenty of things you will get for the price you paid:

  • Filtration Type - 4-stage
  • Air Filtration - Fine Preliminary Filter, True HEPA filter, Activated Carbon filter, Negative Ion Generator
  • Noise Level - ≤30 dB
  • Warranty - 1 year
  • Coverage Area - 107 sq. ft.

It's hard to believe that RIGOGLIOSO portable Ionizer air purifier manages to include a 4-stage filtration that works seamlessly together in providing clean air. First, you have a fine preliminary filter that blocks dust, hair, and other big particles. The inner true HEPA filter will trap common allergens like mold, pollen, pet dander, bacteria up to 99.97% efficiency. The activated carbon filter will remove close-range smoke and odor like cigarette or smelly washroom. Lastly, the anion sterilization will discharge negative ions to will merge with positive ions pollutants in the air. The merged ions will fall due to the increased weight allowing the air cleaner filter to capture it all.

RIGOGLIOSO Ionizer True HEPA air purifier can cover up to 107 square feet at high speed. Not the greatest output but it will do well in small room sizes like offices and bedrooms. We recommend getting one in your workplace if you are an asthmatic person as an air purifier can make a big difference.

RIGOGLIOSO ionizer air purifier is very quiet at less than 30 dB noise output. That's bordering the sound of whispering so no problem plugging it next to your laptop while you work. The soft nightlight function also works great in the bedroom that provides sleeper added comfort and security. We only wish you can turn off the night light completely during the day time. Power usage is very low at less than 2.5 watts with a DC5 voltage. Great for all-day use and friendly to the electric bill.

Being a USB-powered air cleaner, airflow performance has to take a hit. Combining with the small filter size, do not expect the same quality as a console air purifier. The 6 months filter lifespan is standard but can be a hassle to change. The only unique feature that we are annoyed with is the default Sleep mode that has an 8 hours countdown timer. Not only that, it does not completely turn off the indicator light.

In short: A portable USB air purifier that cost around $30-40. Small coverage but works great at desk particularly if you are a smoker.

House in a simple yet functional modern case, Intelabe EP1080 is very portable at a tad above 3.3 pounds in weight.

The debating section that all users should know. Intelabe EP1080 air purifier uses an efficient HEPA filtration system that is very robust for its compact size.

Enhanced by the new brushless, noise-free fan. Intelabe EP1080 is very suitable for sleep, work, or study as the noise level is only between 22 decibels to 49 decibels. Switch it to the lowest speed if you enjoy complete silent or second speed for soothing white noise. The 15 watts power usage is also energy-saving for daily 12 or 24 hours operation depending on your preferences.

Let's address the elephant in the room. Intelabe EP1080 does not come with an activated carbon filter as the brand believes it will volatilize harmful substances back into the air after some time. Like it or not, the lack of a carbon filter does make the air cleaner less compelling than the others. Besides that, you have the typical setbacks found in an air purifier under 50 like the short filter lifespan and no autonomous support. Still, we would whole-heartedly recommend Intelabe EP1080 as it is cheap, functional, and will provide you with clean, fresh air.

In short: A slightly unconventional 3-stage HEPA air purifier without an activated carbon filter. In return, you gain an antibacterial cloth and extra air filter with fragrance sponge.

Why is My Air Purifier Not Working?

If you feel your air purifier is underperforming or barely doing anything, there could be external factors that are causing it. First of all, check if the budget air cleaner has enough capacity to cover the entire room. A small air purifier will not able to clean the air swiftly when placed in a large room. For optimum performance, you should always run at the highest fan speed setting so more pollutants will be removed from the air. Secondly, check if the filters are clogged with trapped particles like dust or hair. An air cleaner with not work efficiently with a dirty filter. Clean or filter replace it from time to time. The third and final mistake most people didn't realize is they left their window open when the air purifier is running. This causes the air purifier to overwork as filtered air will flow out while dirty air will flow in continuously. Always run an air purifier with windows closed.

What To Look For In The Best Air Purifier Under $50

The right air cleaner can bring health and happiness to you simply by purifying the air. We already covered what to expect in an air purifier below 50 price point. You probably have checked out the other air purifiers' in-depth review here. If you are still in the market for an affordable air cleaning machine, here are the key features to look for.

  • Size and quality - All budget air purifiers are lightweight and portable. So instead of just focusing on the dimension, you should look at the build quality, the material used, and the durability. A good quality air cleaner should last you at least a couple of years without fail.
  • Room size - Even though most budget machine purifying coverage is small, there is no harm in picking a model with a higher capacity. In any case, measure your room square footage first and pick an air cleaner that can cover the space at a minimum of 2 air changes per hour.
  • CADR - Clean Air Delivery Rate is an official AHAM to measure the air cleaning capacity of the air cleaner. Most low-priced air purifiers do not participate in this measurement thus it is not an accurate analysis.
  • Air filtration - The better the filtration, the more contaminants will be captured by the air cleaner. Higher priority should be given to a model that comes with a True HEPA filter and an activated carbon filter. There are models that come with advanced cleaning technology like UV-light or ionizer to supplement the standard trio.
  • Filter lifespan - Due to the small filter size, anticipate a filter usage life between 3 to 6 months with 12 hours of daily operation. The longer the filter lasts, the cheaper and fewer maintenance is required.
  • Warranty - The longer the warranty, the better the assurance you will get from the product. Any model that does not come with a minimum 1-year warranty should be ignored. Consider the warranty terms, replacement policy, and after-sale service as well.
  • Addons - Example Auto mode, sleep mode, timer, or night light, or any features that would enhance the usability is appreciated.
