User Experience

When I first started using this product, I noticed a significant improvement in air quality and a reduction in allergens in my home. The built-in automatic air sensors are sensitive and efficient, adjusting the speed of filtration as needed. However, I have experienced an irritating, high-pitched humming noise coming from the unit, which can be disruptive in an otherwise quiet room. Despite this downside, the product effectively cleans the air with its HEPA filter and airflow volume, making it a worthwhile investment for those seeking better indoor air quality.

Elechomes Air Purifier With True HEPA Filter

Best Air Purifier for Smoke

Smoking indoors can cause odors to linger, as smoke smell clings to your furniture and carpets. There are also much higher levels of respirable suspended particles, such as nicotine, in smokers’ houses than in non-smokers’ houses.

Thankfully, this air purifier is fitted with an ozone-free three-stage filtration process. It can filter 99.97 percent of pollutants in the air.

Its process includes a true HEPA filter that targets the tiniest airborne particles. On the other hand, the carbon filter helps eliminate odors, creating fresher air for smokers.

  • Aromatherapy function allows you to add essential oils.
  • Compact size so you can pop it on a desk or table.

Personal Perspective

My experience with this air purifier has been a mix of positive and negative aspects. On one hand, it's compact and unobtrusive, fitting nicely in various locations around the house, and works well in spaces like my office or living room with free roaming bunnies. It's also relatively quiet, allowing for undisrupted sleep when used in the bedroom. However, I've found the filters to be quite pricey, almost reaching the cost of the device itself, which makes me question its overall value. Despite this drawback, the air purifier effectively cleans the air and even allows for the use of essential oils to add a pleasant scent.

Jinpus Air Purifier

Best Budget Air Purifier

If you’re looking for an effective air purifier that won’t send you running to the bank, look no further.

The Jinpus air purifier has a HEPA filter, which removes airborne pollutants such as pet dander, pollen, and bacteria. This powerful air purifier boasts an almost silent operation (around 30 decibels) for quiet cleaning.

  • Highly efficient, 360-degree air purification.

  • LED light may disturb sleep as it cannot be completely switched off.

My experience with this mini air purifier has been quite positive overall. As someone who lives with a smoker, I've noticed a significant improvement in air quality and reduced odors in my room. The device is small, quiet, and emits a calming blue light, which doubles as a nightlight. While I can't say for certain that it has reduced mold particles, I have experienced fewer headaches since using it. Although it doesn't come with a plug and the nightlight feature can't be turned off completely, I still highly recommend this purifier for its effective performance and budget-friendly price.

Enoch Car Air Purifier

As a frequent driver, I appreciate how it removes unwanted odors, such as smoke, quickly and efficiently. The built-in charger is a nice bonus, although I do wish it had fast or rapid USB ports for my daily charging needs.

Why Buy an Air Purifier? (Buying Guide)

Is it worth spending money on something that will just sit quietly in the corner of your room?

Air purifiers are good for your health. They remove airborne particles of dust and mites, mold, allergens, and smoke from your indoor air. Besides these, they also eliminate other nasty microscopic pieces you might be unknowingly inhaling (2).

For instance, an air purifier may be a good investment if you or someone in your household is prone to getting sick. These can trap bacteria and viruses that cause illness.

Types of Air Purifiers

There are various types of air purifiers to choose from:

Ultraviolet Air Purifiers

UV air purifiers remove harmful viruses, bacteria, and pathogens from the air using ultraviolet light (3). They can remove 99 percent of microorganisms present in the air, such as mold spores.

This type of air purifier is inspired by the medical use of UV light in hospitals to disinfect laboratories and patient rooms.


  • Kill germs, viruses, bacteria, and mold, which cause illness.
  • Less maintenance than filtered purifiers.
  • Use less electricity compared to other purifying systems.


  • Bulbs must be replaced frequently, depending on the frequency of use.
  • Dust can decrease the efficiency of bulbs.

HEPA Air Purifiers

HEPA (high-efficiency particulate air) air purifiers have a dense HEPA filter.

It traps up to 99.99 percent of particles (over 0.3 microns) in the air.

These include pollen, dust, and mold.

They are designed to tackle volatile organic compounds (VOCs). Some will also work alongside HEPA filters that will remove other particles from the air.


  • Effectively remove odors, smoke, and other chemicals in the air.
  • Particularly useful for those sensitive to smells.
  • A great power combo when combined with a HEPA filter.


  • Ineffective for the elimination of pollen, dust, and mold.

  • Able to remove anything (except odors) from the air.
  • There aren’t any filters you need to clean or replace.


  • Generate ozone, which is potentially harmful.

Electronic Air Cleaners

Electronic air cleaners are equipped with HEPA filters and positively charged ions. These work with your air conditioner to remove almost all allergens in the air.

Electronic cleaners ensure that the air that travels through your home’s HVAC system passes through filters, which trap larger particles. The smaller particles are then caught by electrically charged filters, which prevent them from circulating in your home.


  • Effectively remove dust, bacteria, viruses, fumes, and smoke from the air.
  • Able to catch the smallest of particles.

  • Efficient at removing small particles such as pollen and dust.
  • Limits the impact of allergies and viruses on your health.
  • Extend your air conditioner’s lifespan by filtering out particles that affect its functionality.


  • Require professional installation.
  • Costly, ranging into the thousands.

Air-To-Air Exchangers

Air-to-air exchangers provide ventilation throughout your home by replacing stale air with fresh air. They use energy recovery ventilators (5). This means that, for instance, in cold weather, the air-to-air exchanger will trap heat in the air. Whereas, during warmer seasons, the air-to-air exchanger will cool the clean outside air entering your home.


  • Regulate temperature and humidity within the home.
  • Reduce the presence of mold in the air, which can prevent illness.
  • Improves the air quality inside a building or home.
  • Flushes out odors and indoor pollutants.


  • Expensive to install and run since it uses electricity often.
  • Maintenance is ongoing, time-consuming, and expensive.

Choosing Your Air Purifier

True HEPA Filter

These filters catch 99.97 percent of the smallest particles in the air, including dust, pollen, and pet dander (6).

Reusable Pre-filters

Reusable pre-filters trap large particles in the air and prolong the primary filter’s lifespan in your air purifier. You can also wash them, allowing you to save money on replacement filters.

UV Light

UV light eliminates bacteria, viruses, and germs that cause illness, helping to create a clean and sterile living space.

Filter Change Indicator

This indicator means you don’t have to guess when the filter in your air purifier needs to be changed; the indicator will tell you.

Air Quality Sensor

This allows for a ‘hands-free’ system, as it regulates the air quality by identifying toxins. Then it automatically adjusts the fan speed to eliminate them quickly and restores its regular operation.

Energy Star Label

This label distinguishes air purifiers that are environmentally friendly, have low operating costs, and greater efficiency levels.

Remote Control

This provides an element of convenience. Air purifiers with a remote control feature allow you to control the settings from anywhere in the room. You no longer have to fiddle around with the buttons on the purifier itself.

How Do I Detect an Indoor Air Quality Problem?

Pay close attention to your allergies. Note the appearance of new symptoms, such as coughing or sneezing. If you frequently suffer from bronchitis or pneumonia, it may result from pollutants contaminating your indoor air.

Consider your external environment. Is there construction happening near you? Or has there been a fire nearby? Residual smoke and dust can contaminate your indoor air quality (10).

How Can You Improve Indoor Air Quality?

Besides investing in an air purifier, there are several things you can do to improve the air quality in your home.

  • Change your air conditioning filter regularly, especially if you live in a polluted area.
  • Use cooking vents in your kitchen to limit fumes and odors.
  • Clean as often as possible and vacuum your rugs and carpets regularly to limit dust accumulation around your furniture.
  • Allow fresh air in whenever possible (11).

What Are CADR Ratings?

CADR stands for Clean Air Delivery Rate. The higher the CADR rating of an air purifier in cubic feet per minute, the more air it cleans. Different particle sizes (smoke, pollen, and dust) should be given their own rating.

You can use CADR ratings to compare the performance of different air purifiers. It indicates how fast an air purifier can clean the air in a particular room.

Do Larger Air Purifiers Have Better CADR Ratings?

The size of the air purifier may not always determine its CADR rating. High CADR ratings come from an air purifier’s high fan power, filter surface area, and ability to cover the air in an ample space.

Where Should I Place My Air Purifier?

Small air purifiers are handy as they can be moved from room to room as needed. When deciding where to place your air purifier, choose the room(s) you spend the most time in. It may also be wise to choose the room(s) you think are most affected by air pollutants.

The ideal location for an air purifier is in the middle of a room, with no objects blocking it and preventing the air from reaching it. However, this may cause a tripping hazard. So try to aim for at least 3 feet of space between the device and a wall or piece of furniture (12).

What is the Best Air Purifier at a Reasonable Price?

The best air purifier at a reasonable price is the Coway Airmega AP. It costs almost half the price of other models, and yet it has four-stage filtration, built-in smart features, and sensors to take away the guesswork.
