Indoor air quality is critical to overall health and well-being, mainly when most of us spend our maximum time indoors. The discussion over the effectiveness of an air scrubber vs. an air purifier always remains. 

What’s the difference between the two? Which one is better for improving indoor air quality? Let’s delve into the specifics to determine which one to select.

They both remove pollutants from the air and make it clean for breathing. Each has its own set of benefits and drawbacks. Read on to explore how they work and which is the right choice for your space.

Major Differences

Both devices serve the same purpose. However, they differ in the way they work and the results they produce. An air scrubber draws air into itself, filters it, and then expels the cleaned air out. 

Conversely, an air purifier draws in air and passes it through multiple filters to capture and trap impurities such as dust, pollen, smoke, and pet dander. 

Most air purifiers employ HEPA filters  to capture tiny particles (up to 0.3 microns).

Here are some critical factors to account for when choosing between an indoor air pollution scrubber and an air purifier:

Purification Method

  • Air scrubbers and air purifiers use different methods of purification. Air scrubbers produce ionized oxidizers as part of their purification process. 
  • These negatively charged oxidizers attract positively charged pollutants in the air, such as odors, smoke, and other substances. Air scrubber uses a combination of mechanical filtration and ultraviolet light.
  • Air purifiers rely on fans to draw air through one or more filters. It traps harmful impure particles in the filter and prevents them from recirculating back into the air. 
  • Fans promote equal airflow in the room, resulting in evenly-distributed cleaned air. 
  • Air scrubbers work as purifiers can remove odors and smoke from the air to some extent. An air scrubber is your best bet for more fragrant purification.


Size and Capacity

  • Air scrubbers and air purifiers come in various sizes and capacities to suit indoor environments. An air scrubber is typically heavy and more powerful than an air purifier. 
  • It can clean air much faster, up to four times every hour. Its higher and constant air movement handles a greater volume of airborne contaminants. An air scrubber is better suited for large commercial or industrial environments.
  • In contrast, the air purifier is compact and lightweight. It’s more appropriate for use in homes, offices, and other small spaces. 
  • It offers a variety of sizes and capacities, depending on the user’s specific requirements. You can calculate the air purifier size according to your room.


Noise Level

  • Depending on their design, model, and features, air scrubbers and air purifiers can produce varying noise levels. 
  • Generally, an air scrubber tends to be louder than an air purifier due to its larger size and more powerful motors. 
  • However, many modern and advanced air scrubbers are manufactured with noise-reduction features such as insulated housings, variable fan speeds, and quiet mode settings.
  • The air purifier appears thinner and quieter. It comes up with noise levels ranging from barely audible to moderate, depending on the model and technology. The reason is that air purifier fans and air filters are run at a low noise level.


Maintenance and Replacement Cost

  • The air scrubber is usually more expensive to maintain and replace. It requires more frequent inspection and cleaning than an air purifier. 
  • Regular maintenance of air scrubbers’ motors and other components, filter replacement, and air cleaning device’ upkeep can incur high expenses.
  • The air purifier is less complicated and demands minimal maintenance and servicing. This lowers the total cost. Check the filter regularly and replace it if needed to maintain optimal performance. 
  • In most cases, long-lasting filters do not require regular replacement. Additionally, the replacement filters are inexpensive and easy to repair and install.

Which One is More Effective? Air Scrubber or Air Purifier?

The difference between an air scrubber and an air purifier lies in the types of particles they clean. 

Using each device correctly can achieve cleaner and healthier indoor air quality. 

Air scrubbers or air purifiers produce purified air depending on their model, technology, and features. 

It’s essential to consider your specific needs, the space size, and the air filtration level required. Investing in a top-notch air purification system can give you more accessible and safer breathing while fostering a healthier indoor environment.

Aside from the key points discussed above, an air scrubber holds an edge due to its long-lasting durability and deep air cleaning.

Bottom Line

Air purifiers and air scrubbers improve air quality by removing harmful particles from the air. 

Both reduce the risk of respiratory allergies and issues like asthma. An air purifier is helpful for general air cleaning needs. 

An air scrubber is ideal for situations where hazardous particles and odors need to be cleaned. 

Both work splendidly, enabling you to say goodbye to poor indoor air quality and breathe in a safe atmosphere. You can enjoy cleaner and healthier air in your indoor spaces by selecting the right device for your needs and using it properly.

Frequently Asked Questions

Air purifiers equipped with HEPA filters are deemed to be among the safest. They can remove many toxins from the air, including viruses and bacteria. Also, they do not emit ozone and keep your surroundings safe.

The energy consumption of an air scrubber depends on its specific design and usage patterns. If you use it moderately daily, it will not cost you more electricity.

The lifespan of an air scrubber can vary depending on factors such as its usage, maintenance, and the quality of its components. Typically, air scrubbers can last for several years before requiring replacement.
