Best Cheap And Affordable Air Purifier Under 100

How Do We Measure?
Selling price There are plenty of powerful True HEPA air purifiers under $100 you can buy. However, when you are on a tight budget, there is no one size fits all. Most affordable air cleaners prioritize accessible price point over air cleaning efficiency. Some devices focus on portability and others focus on special features such as advanced dust removal or smoke filtration. We will review every device based on the number of features and purification performance it can churn out. The best air purifier for the money is slightly above $100 dollar while the cheapest is around $50. Whatever models you are looking for, this is the place to find great value devices without overpaying or compromise much.
HEPA filter The second most important measurement in our best affordable air purifier hunt. A True HEPA filter will be able to filter out 99.97% of tiny irritants as small as 0.3 microns. Without the allergens lingering around the house, we will breathe easier and less chance of falling sick from a cough or a cold. What we want from the budget air cleaner is to have a workable, HEPA filter. Bonus points will be given to a model that uses a True HEPA filter than a HEPA-type filter as microscopic allergens are much harder to catch.
Carbon filter Our criteria are simple. No carbon/ deodorization filter, no feature in our top-rated air purifier you can buy for less than 100 bucks list. A lot of the budget-friendly air cleaners do not come with a carbon filter due to the price constraint. That would not sit well for us as odor contaminants are equally as irritating as non-gas particles. Breathing in dirty air may result in different health complications. Your allergies could easily be triggered by tobacco smoke, chemical fumes, and pet odors. As a bonus added points, we will test and rate the smoke filtration efficiency of every device in our evaluation.

One of the best inexpensive air purifier to purchase with many pedigrees. Fellowes AeraMax 100 is officially certified as an allergy and asthma-friendly air cleaning device. It is also AHAM/ CARB certified and independently tested to be effective in removing the influenza virus from indoor air. All this is achievable through the 7.3 x 27.3 x 8.5 inch slim tower body and 9.9 lb weight. You can easily carry it to any room that requires air purification. Very useful if you have asthma or hypersensitive to allergies.

Let's touch on Fellowes AeraMax 100 multi-layered PlasmaTRUE air purification:

  • True HEPA Filter - Remove microscopic airborne particles with a 99.97% efficiency rate
  • Carbon filter - Get rid of household smoke and odors via absorption
  • AeraSafe antimicrobial treatment - Inhibit mold and bacteria growth
  • PlasmaTrue technology - Generate ionized field to help pull down airborne pollutants for the filter to capture
  • 100 sq. ft. purifying coverage - Suitable for personalized areas

Unlike a HEPA-type filter, the true HEPA filter can capture 99.97% of the household pollutants as small as 0.3 microns including viral viruses, dust, pollen, mold, and pet dander. At such a bargain of a price, the HEPA filter even comes with an antimicrobial treatment that inhibits odor-causing mold and mildew growth. Next, the standalone carbon filter will trap household fumes, cigarette smoke, and pet odors with relative ease. Completing the filtration is the Fellow's own PlasmaTRUE technology. An ionizer that releases negative ions to merge and pull airborne impurities down so it can be easily captured by the HEPA filter. Surprisingly, there is no dedicated pre-filter for quick dust removal. Rounding up with the 100 to 200 sq. ft. areas, you can practically place AeraMax 100 in any corner of the house.

Fellowes AeraMax 100 provides great value for your money with its top HEPA filtration quality. Changing the HEPA and carbon filter is easy through the back panel and you only have to do it annually. Even though it is the mid-tier model, AeraMax 100 offer cheaper price point yet manage to retain most of its useful features. You have a front air quality indicator that detects and displays how clean the air is in the room. The filter indicator will remind you to replace the filter once it is clogged or worn out. An adjustable 3 fan speed with Aera+ mode (for flu season) and Auto mode that automatically set higher speed when air pollutants are detected. The built-in AeraSmart Sensor is very sensitive in detecting nearby contaminants which is uncommon for an air purifier of this price segment. The quiet operation helps keep noise level down so you can run it all-night during sleep. At around 37 to 51 watts, power consumption is low too despite not having sleep mode. The drawback for AeraMax 100 is the lack of a timer, low CADR return, and weak airflow. Dust CADR is at 65 cfm, Pollen CADR is at 75 cfm, and Smoke CADR is at 68 cfm. Great in cleaning the air in the bedroom probably not the best option for large spaces like the living room.

In short: Delivers fresh air at fraction of the cost compared with other premium model, Fellowes Aeramax 100/ DX5 fits well in our compact budget criteria. Go with this if you want an affordable 4-stage tower air purifier that is effective yet energy efficiency.

We might be "deceiving" on this one as the price is slightly above $100 after the discount. Regardless, GermGuardian AC5250PT is an air purifier on a budget that somehow manages to fit in a 5-stage filtration. Being the only tower air cleaner listed here, GermGuardian AC5250PT will take up very little of your interior space. The 6.1 x 27.3 x 9.5 in sleek body design and 10.5 lb weight fits well in a tight corner. You can easily carry the AC5250PT to other rooms that require air cleaning. That said, airflow capacity has to take a dip to accommodate its tower form body. Official dust CADR is at 123 cfm, pollen at 128 cfm, and smoke free at 116 cfm. Suitable for people struggling with seasonal allergies.

Let's look into GermGuardian AC5250PT 5-stage filtration:

  • Charcoal pre-filter - Reduce dust, smoke, odor, and other gases coumpounds
  • True HEPA with Pet Pure antimicrobial - Remove microscopic allergens and inhibit the growth of mold
  • UV-C Light - Kill bacteria and viruses
  • TIO2 treatment - Reduce VOCs in the air

The bundled filtration set includes a charcoal pre-filter, True HEPA filter, antimicrobial, and UV-C light. The dual carbon pre-filter would trap large contaminants plus, toxic fumes, and odor. Next, the True HEPA filter will target microscopic particles as small as 0.3 microns with a 99.97% capturing efficiency. UV-C light with TIO2 will eliminate (kill not trap) germs, viruses, and bacteria for good. The Pet Pure treatment aka antimicrobial will inhibits microorganisms' growth. On top of it all, the worry-free 5 years warranty is the perfect cherry on top. Adding all the bundled filtration, the price can easily shoot out to $200 on a competitor's model. GermGuardian AC5250PT Pet Pure can be yours for around $150 including filters. There is no better filtration package you can get at this low price range.

GermGuardian AC5250PT can cover a modest 193 square footage of space while running quietly in the background. There are 5 selectable speeds that you can manually set according to the room air quality. A programmable timer with an informative digital display is also included that lets you set a time to shut off the air cleaner. On the cons, filter cost is on the higher side as there 5 parts required replacing. The lack of built-in sensors and air quality indicator is the most obvious exclusion here. Autonomous operation is nowhere to be found but understandably so as it falls under the entry-level category.

In short: The ideal model to protect you from cough, cold, and other common allergies. GermGuardian AC5250PT is easily one of the best value air purifiers with a complete 5-stage HEPA filtration plus germ-killing UV-light. You do have to fork out a little bit more money for the extra features and long warranty.

The smallest and most affordable HEPA air purifier under $100 (or 50 after discount). GermGuardian AC4100 might not be the new kid on the block, it still manages to squeeze in a respectable 3-in-1 filtration. The speaker alike exterior is pleasing to the eyes and gains the portability perk where you can bring it during travel. You can even run it in a vertical or horizontal position without impeding the airflow. As such, AC4100 can be placed at any location including top shelf, bedside table, or desk. Operational wise, GermGuardian AC4100 is also very easy to use with a dial knob that controls the 3 fan speed and a UV-C light control button. Even running at the highest speed, it will not disturb your sleep. However, there are zero supportive features to enhance the overall usability. It is the most basic form of air cleaner you can get.

Let's look at GermGuardian AC4100 air purifier filtration bundled:

  • Charcoal + PCO Filter - Capture dust, hair, light smoke, and odors
  • HEPA filter - Remove up to 99.97% of airborne allergens down to 0.3 microns
  • UV-C Light - Eradicate germs and viruses
  • TIO2 treatment - Combines well with the UV-C to reduce VOCs
  • 78 sq. ft. purifying coverage - For desktop, bedside use

Despite the small 6.5 x 11 x 7.5 in body and 4.85 lb weight, you’ll get HEPA filter, charcoal + PCO filter, and UV-C technology as standard. Yes, UV-C light is included that specializes in killing bacteria and viruses in the air. Dual function charcoal pre-filter will reduce household dust, hair, cigarette smoke, and VOCs. The main HEPA-filter will get rid of 99% of illness-causing allergens in the air. The maximum of 78 square feet coverage is very restricted for close-range purifying but can still reduce allergic reactions linked with bad air. Not bad for a small air purifier that is supposed to cut costs at every corner.

For the low price you paid, GermGuardian AC4100 is a great deal but it can only do so much. The small body means you have to compromise on a few things, mainly the filter size and performance. A HEPA-type filter is not the same as a True HEPA filter. The airflow delivery rate is also limited but in-return is a noiseless operation with low power and noise output. You can easily bypass the drawbacks we mentioned with other more premium models in this list.

In short: Cheapest 4-stage HEPA air purifier that costs even less than some air cleaners' filter. For around 50 dollars, GermGuardian AC4100 is still an ideal model that is dirt cheap and doesn't mind the small purifying area.

Need a budget-friendly air purifier as you don't have any cash to spare? In comes Hamilton Beach TrueAir Compact Pet 04384. A small and simple device with the sole purpose of circulating clean air into your room. Like AC4100, both models have many similarities including the pet focus setup, low-noise operation, and low filter cost. You only have to pay around 10 dollars annually on the carbon filter replacement cost. At 8.1 x 16.4 x 10.8 inches in size and 6.3 pounds, you can run Hamilton Beach TrueAir in a horizontal or vertical position without disrupting the airflow. Perfect if you intend to place it in a tight spot and nighttime without having to afraid that the air cleaner will accidentally tip-over by your pets.

Moving on to the specification, here's what you will get with the 3-stage filtration:

  • Pre-filter - First-stage filtration that collect dust contaminants and protect the inner filters
  • HEPA-grade filter - Reusable and washable filter that remove non-smoke particles
  • Carbon zeolite filters - Traps light smoke, odors, and gaseous impurities
  • 140 sq. ft. purifying coverage - For small room use

The main highlight is obviously the permanent filter. The permanent HEPA-grade filter that has a 99% efficiency in removing PM2.5 impurities in the air. The best bit of all, you can vacuum out the captured pollutants and reuse the HEPA filter for many years to come. Given the low base price and size constraint, Hamilton TrueAir pet still comes with 2 carbon zeolite filters. An optional filter that offers better smoke and odor filtration without adding much to the cost. Setting it to max speed, Hamilton TrueAir pet will effortlessly eliminate airborne irritants within its 140 square feet purifying range.

Let's get the usual cons out of the way for air purifier in this budget category. It has a weak HEPA-type filtration, limited coverage, and basic features. Besides the filter change indicator, there is no auto mode, sleep mode, timer, or air quality indicator. However, at around $60 price points including a set of carbon filters, Hamilton Beach TrueAir is an absolute bargain and a great deal for a first-time buyer. You can even wash the HEPA-type filter to extend the filter lifespan and save the money for something else. If for some reason you think Hamilton Beach TrueAir is still too expensive, here are two more affordable options from the series you could opt for. If you are willing to give up on the carbon zeolite filters, no doubt the cheaper TrueAir models would better suit your budget.

In short: A simple and capable air purifier under $100 with a permanent HEPA filter to keep cost low. Fits a small budget requirement and works well in small areas. Dirt cheap to maintain if you don't mind the lack of supportive features.

For a 100% ozone-free and AHAM certified model, this is a phenomenon considering the number of emerging air cleaners released. At 8.7 x 14.2 x 8.7 in and 8.8 lb size, LEVOIT Core 300 is not the smallest air purifier here, but portability will never be an issue. The same story with the noise level and power consumption, LEVOIT Core 300 will operate silently at 24 dB to 50 dB white noise that can even help you sleep better. Besides the bedroom, you can also run LEVOIT Core 300 efficiently in the kitchen, living hall, and office room. Being an Energy Star rated unit, expect an average of 45 W power usage hourly.

  • Activated carbon filter - Remove unhealthy gaseous compounds and household odors

The pre-filter will trap the biggest particles in the air while extending the life of the other main filters. LEVOIT Core 300 does not use a cheaper HEPA-type filter like most small and affordable air purifiers. It uses a True HEPA filter that can remove 99.97% of dust, dust mites, mold, pollen, pet dander, fungi in the air. The High-Efficiency activated carbon filter can neutralize smoke and odors that you will typically find in a household. You can even choose to upgrade the all-in-one filter with a Pet Allergy Filter that is super effective against pet odors, diapers, and cooking smells. Toxin Absorber Filter specializes in air pollution like ciggy smoke, vehicle exhaust, and volatile organic compounds (VOCs).MB Filter that neutralizes germs and impedes regrowth of mold on the filter. Removing harmful contaminants would be a piece of cake.

LEVOIT Core 300 is not shy about features too. You have an auto-off timer and a mid-range purifying radius that covers up to 219 square footage of an area. It is also backed by a 5 years warranty that alleviates any fears of the device from breaking down. The handy child lock is also present while you can lock the controls to prevent children from filling with the buttons. No surprise that LEVOIT Core 300 has built its own fan base and rightly calls for a spot here. Nitpicking on a few tiny problems, the small filters have a short 6-8 months of lifespan. Expect to pay 20-40 dollars on the filter replacement cost. Auto mode is also not present here. So if you plan to move up from the stable line in the near future, you know what to look out for.

In short: Affordable HEPA air purifier with decent airflow performance and backed by a 5 years warranty. Upgradable filter for a household that is dealing with specific types of pollutants.

The phrase what you paid is what you get does not apply to Levoit LV-132. A budget-friendly air purifier with the deal clincher nightlight. The nightlight is very useful so you don't trip over objects while trying to navigate through the dark. If you have toddlers at home, the nightlight will help the little ones sleep comfortably at night while the air cleaner restores the freshness of the air. With 2 adjustable brightness settings, you can reduce the light intensity or turn it off during day time. This will help save energy and extend the lightbulb usage lifespan. Another highlight of Levoit LV-132 is the low 43 dB noise output at max speeds. The 3 selectable speed is very easy to use despite the lack of Auto mode. As expected, the filter change indicator and 2 years warranty are standard with all Levoit models.

Levoit LV-132 offers a competitive specification that is no easy pushover as such:

  • Fine preliminary filter - Trap large particles like dust while protecting the inner filter
  • True HEPA filter- Performs well in capturing microscopic particles at 0.3 microns and 99.97% efficiency
  • Activated carbon filter - Remove gaseous compounds and odors from cooking, pets, cigarette, and detergent
  • 129 sq. ft. purifying coverage - Ideal for small spaces

Here's the reason why this is the best air purifier for smoke under $100. Powering the machine is a 100% ozone-free, 3-stage purification that includes a fine preliminary, mandatory HEPA, and carbon filter. The fine preliminary filter AKA pre-filter will trap only dust, hair, and debris. The well-protected True HEPA filter will focus on removing microbes and allergens that cannot be seen through our naked eyes including dust mite, dander, pollen, mold, and bacteria. The last-stage carbon filter will focus on trapping light smoke particles and odors that we might not realize it is degrading our indoor air. Ammonia, radon, VOCs, CO, CO2 are some of the toxic gases that will be removed by the air cleaner. Completing the filtration is a decent 129 square feet coverage that is perfect for bedroom, kitchen, or baby changing room. The compact 9.7 x 14.6 x 9.8 in size and 6.6 lb lightweight cylinder shape body means moving from room to room is not an issue.

Breathing in clean air will bring many health benefits and Levoit LV-132 is a well-rounded product at this price range. Even though pricing is slightly higher compared to other entry-level air cleaners, it is still below the $100 benchmark and a unique feature that no others could offer. We appreciate the inclusion of a True HEPA filter and a dedicated carbon filter despite the limited space. Speaking of limitation, the small filter size and 6 months lifespan are unavoidable given its compactness. The 110 cfm CADR is not great but workable for a small purifying area with no major indoor pollution concern. Levoit LV-132 is ideal for a person that has breathing difficulty or allergies.

In short: A capable true HEPA air purifier with a low price tag and match with a lower filter replacement cost. Odor removal may not be its strong suit, the all-around purification will make up for it. This is also the only model here that comes with a dimmable nightlight feature.

Additional Information

What Can A Cheap Air Purifier Do?

You don’t have to spend a fortune on an air purifying device. "Cheap" is a very loose term that would have a whole new interpretation for different sets of people. Let it be an air purifier under 200, 100, 50, or a heavily discounted model, there a lot of things an air cleaner can do. Most importantly, it can provide clean air despite having a low price tag. Breathing in purified air can relieve allergic reactions like sinus, itchy skin, dry cough, sore throat, watery eyes, and nausea. It can also prevent seasonal allergies like viral flu and asthma from triggering. In long-run it can protect you from sickness like COPD, pneumonia, bronchitis, dementia, and heart disease. Another thing a lot of didn't realize that air cleaner can brighten your mood, reduce stress, help you sleep better, and lower blood pressure. The only key differences between cheap (poor quality) and price cheap are the end result. The best budget air purifier can still provide exceptional value within its capacity. As a matter of fact, many of the best-selling models are typically in the entry-level segment.

Are Cheap Air Purifiers A Waste Of Money?

An affordable air cleaner won't be a waste of money as long as it can improve air quality by removing airborne pollutants, allergens, and toxic gases. Even if the air purifying device that costs less than 50 dollars, it can still prevent respiratory illnesses, slow down dust build-up, and stop mold/ mildew from spreading. An air cleaner will also make the room smell fresher after cooking or cigarette break. That said, purifying effectiveness can be subjective depending on the types of air purifiers.

Cheap VS Expensive Air Purifier

Pricing, room size coverage, types of filtration, and performance are the differences between cheap and expensive HEPA air cleaner. Starting with the pricing, most top-selling, affordable air purifiers will cost $100 or less and still perform remarkably well. Inexpensive models are between $100 to $200 while expensive air purifiers will start from $200 all the way up to thousands. Most low budget air purifiers will cover a smaller room between 60 to 350 square feet depending on the size of the device. Expensive air purifying device can handle a wider amount of room space starting from 300 square feet at 2 air changes per hour.

Having multiple filtrations can help capture all types of airborne allergens, smoke, and odors. There are some air purifiers that come with a single-stage filtration. Avoid those. Instead, go with multi-stage filtration air cleaners that maximize the performance and guarantee your money’s worth. A HEPA-type filter can be found in the lower-range model while True HEPA filter is typically used in more premium models. As for the frequency of filter replacement, anticipate a shorter filter lifespan between 3 to 12 months. Premium air cleaners filter will typically last a year or higher depending on the filter quality.

In general, the pricier the air cleaner, the better specification and filters. That is the rule of thumb although they are a few exceptional cases. If you can extend your budget, go for a higher tier model. As an air purifier is a long term investment, make sure you are making the right decision regardless of the price point.

Is it Safe To Purchase A Cheap Air Purifier?

All air purifiers that use mechanical filters are safe unless it is an Ozonator. An Ozonator or ozone generator will produce harmful ozone that will damage our body's immune system and lung tissue cells. The safest option is to go with a HEPA air cleaner with a built-in motor fan. It will pull in airborne particles, trapped them, and distribute out the purified air.

Do Air Purifiers Use A Lot Of Electricity?

A air purifier will increase your electricity bill by a very thin margin even if you run it every single day. On average of 12 hours daily operation, you will only see an increase of $3 to $5 dollars a month in electricity bills. That's only $36 to $60 dollars annually. For all-day 24 hours operation, just multiply the numbers by 2. The new monthly electricity bill will be $6-$10 or $72-120 annually. Take note that the electricity cost in the United States varies from state to state.

What To Consider When Buying A Cheap Air Purifier

Whether you have a low budget of under 50, 100, 150, or 200, the ultimate goal of an air purifier is to clean the air. Breathing in clean air can alleviate our allergies and pump more oxygen into our lungs. Oxygen can help us being energetic and strengthens our immune system. Any specification or multi-stage filtration should be the drive to achieve the clean air goal. Understanding your needs can ensure you're getting the best out of an air purifier without overpaying it. Be realistic about what you can get within the budget and never compare it with the top tier models. Ready? Here are the tips on how to buy an efficient model with the best possible value return.

  1. Selling price and filter cost - Compare the package you will get with the competitors’ model. Also, account for the replacement filter even if it does not cost much. Consider how many years does it take for the filter price to stack up and match the retail price.
  2. Size and weight - Not a critical factor but it’s worth taking note if you have a very specific dimension. Most models in this segment come in a compact size, therefore, it will not occupy too much of interior space.
  3. Airflow delivery rate and CADR - Clean Air Delivery Rate is the official metric used to measure the purification capacity of an air cleaner. Like airflow delivery rate, it uses CFM (cubic feet per minute) to reflect on the volume of clean air. Look for an air cleaner will the highest airflow or CADR output. The higher the number, the swifter airborne contaminants will be removed..
  4. Room size (Coverage) - Co-relate with the airflow delivery rate. Pick a model that can handle a greater amount of space than the room size you are about to cover. The majority of entry-level models are catered for small room spaces due to the price factor. That doesn’t mean you can’t squeeze the best possible deal out of it. Most recommended room size figures released by the manufacturer are based on 2 air changes per hour. You can determine and measure the square footage of the room by multiplying the width and the length.
  5. Pre-filter - First-stage filtration design to capture large particles like dust and hair. Regardless if is a permanent type or dual carbon pre-filter, it is a must-have filter in our book.
  6. Filtration (HEPA, carbon) - Perhaps the most important feature in the list. Having a good HEPA filter whether in the form of True HEPA (99.97% efficiency/ 0.3 microns) or HEPA type (99% efficiency/ 2 microns) would make a huge difference. carbon deodorization filter is also a necessity in our book. Like HEPA filter, it gives an air cleaner the edge over the others.
  7. UV-light - Ultraviolet technology that requires no cleaning and is effective in killing bacteria and viruses.
  8. Ionizer - Release millions of negative ions into the air to merge with positive ions particles. The extra weight forces the ions to fall for the device to capture.
  9. Additional features - This includes Auto mode, AQ sensors, timer etc. Whatever features the air cleaner can fit in, we’ll take it.
  10. Branding reputation - It’s not easy to find an air cleaner that offers more than 1-year warranty at this price range, so the brand reputation plays a big role here. Do consider the service center location or details of the warranty if repair is needed.
  11. No to ozone production - Never purchase an ozone generator to clean the air in your home. Inhaling to ozone will damage our lung tissue cells, aggravate asthma, and allergies. EPA recommends ozone level not more than 0.08 parts per million at home. So check carefully what technology is used in the air cleaner before making the purchase.
